Why This Recipe Will Become Your New Favorite

This extraordinary pasta dish was born from a recent culinary revelation at my absolute favorite pasta restaurant. The flavors and textures were so captivating that I immediately knew I had to recreate it, but with my own signature twist. What truly impressed me, and what I’ve painstakingly perfected in this recipe, is the incredible creaminess of the kale walnut pesto. My goal was to develop a pesto that defied the typical rustic, somewhat coarse texture often found in traditional pestos, such as a Busiate with Pesto Trapanese.

The secret to achieving this unparalleled creamy perfection lies in a simple yet revolutionary step: straining the finished kale pesto through a fine mesh sieve. This process removes all the fibrous “ruffage” from the kale, leaving behind only the vibrant, concentrated flavor and a silky-smooth consistency that is utterly divine. You simply won’t find a creamier kale pesto anywhere else – it’s a creation I am incredibly proud of, and one that consistently receives rave reviews.

I find immense joy in culinary experimentation, transforming inspirations like that restaurant pasta into accessible and exciting recipes for families. Just as I created my Cajun Shrimp Scampi, this kale and walnut pesto recipe is designed to ignite passion in your kitchen, making cooking for your loved ones an adventure. It’s about bringing delicious, unique, and family-friendly meals to your table with ease and flair.

Essential Ingredient Notes and Smart Substitutions

Crafting the perfect Kale Walnut Pesto Pasta begins with selecting the right ingredients. Each component plays a vital role in developing the dish’s distinctive flavor and creamy texture. Here’s a closer look at what you’ll need and how to make the best choices:

Ingredients for the recipe.
  • Lacinato Kale: The Foundation of Flavor. We specifically call for Lacinato kale, also known as Tuscan kale or dinosaur kale. This variety is crucial because it is far more tender and boasts a milder, sweeter flavor profile compared to its curly counterpart. It integrates beautifully into the pesto without imparting any bitterness. It’s truly a game-changer! You absolutely CANNOT substitute curly kale in this recipe, as its robust and often bitter flavor, combined with its tougher texture, would fundamentally alter the delicate balance and taste of the dish. Many who claim to dislike kale have simply never experienced the nuanced delight of Lacinato kale. Its less crunchy nature also makes it ideal for fresh applications like our Kale and Cannellini Bean Salad.
  • Sausage: The Savory Heart. My preferred choice for this pasta is ground mild Italian sausage, which adds a wonderful savory depth and a hint of spice without overpowering the pesto. Alternatively, you can create your own custom blend using our Homemade Italian Sausage Seasoning mixed with ground pork. For those seeking a vegetarian option or a lighter side dish, the sausage can be easily omitted, allowing the creamy pesto to shine on its own. If omitting, consider adding a pinch of red pepper flakes to the pasta water for a subtle kick.
  • Walnuts: The Nutty Complement. Walnuts are an exceptional pairing with kale, offering a rich, earthy flavor and a satisfying texture to the pesto. Their slightly bitter notes beautifully enhance the mild sweetness of the Lacinato kale. While walnuts are highly recommended, you can experiment with other nuts like pine nuts for a more classic pesto taste or pistachio nuts for a vibrant green hue and unique flavor. Pistachios, in particular, are excellent for crafting a distinctively creamy Pistachio Pesto.
  • Parmigiano-Reggiano: The Umami Enhancer. Parmigiano-Reggiano is not just for seasoning; it’s a cornerstone of this pesto’s flavor and texture. It contributes significantly to the dish’s saltiness and provides a crucial umami depth that brings out the best in all the other ingredients. It’s essential to add the Parmigiano-Reggiano *after* straining the pesto. This timing allows the cheese to melt into the strained liquid, thickening the sauce and contributing to its velvety creaminess as it’s incorporated back into the warm pasta and sausage. Freshly grated Parmigiano is always superior to pre-shredded varieties, offering a more authentic flavor and better melting quality.
  • Extra Virgin Olive Oil: The Emulsifier. A high-quality extra virgin olive oil is key to achieving a smooth, emulsified pesto. Its fruity notes complement the other ingredients perfectly.
  • Fresh Garlic: The Aromatic Backbone. Fresh garlic cloves provide essential aromatic depth. Adjust the quantity to your preference, but don’t skip it!
  • Kosher Salt: Seasoning to Perfection. Salt is vital for enhancing all the flavors. Remember that Parmigiano-Reggiano is salty, so taste and adjust as needed.
  • Fresh Basil Leaves: A Hint of Sweetness. A few fresh basil leaves add a touch of classic pesto aroma and sweetness, rounding out the flavor profile.
  • Lemon Juice: The Brightening Agent. Fresh lemon juice cuts through the richness of the pesto and sausage, adding a necessary bright, acidic lift that makes the dish pop.

Step-by-Step Guide to Crafting Creamy Kale Walnut Pesto Pasta

Creating this rich and creamy pasta dish is a straightforward process when you follow these detailed steps. Get ready to impress with minimal effort!

Kale leaves removed from stems.

Step 1: Prepare the Kale for Optimal Texture. Begin by preparing your Lacinato kale. Hold the thickest part of the kale stem firmly between your thumb and forefinger. With your opposite hand, create a tight circle with your thumb and forefinger around the stem, then pull downwards to strip off the tender leaves. Discard the tough stems, as they can contribute to bitterness and an undesirable texture in the pesto. This ensures only the most palatable parts of the kale are used.

Boiling and blanching kale.

Step 2: Blanch and Chill the Kale for Vibrant Color. Bring a large pot of water to a rolling boil. Season the boiling water generously with salt – much like you would for pasta, as this helps season the kale. Carefully add the prepared kale leaves and blanch them for a mere 30 seconds, using tongs to turn them frequently to ensure even cooking. Immediately remove the blanched kale and plunge it into a large bowl filled with ice water. This ice bath is critical as it halts the cooking process, preserving the kale’s bright green color and tenderizing it slightly. Once cooled, thoroughly squeeze out as much water as possible from the kale. This step is crucial for preventing a watery pesto, and sets the stage for ultimate creaminess. Set the squeezed kale aside on a plate.

Processing walnuts with fresh garlic, salt, and kale.

Step 3: Begin Pesto Creation in the Food Processor. In the bowl of a food processor, combine the walnuts, peeled garlic cloves, and a teaspoon of kosher salt. Pulse until the walnuts are finely ground, creating a textured base. Next, add the blanched and squeezed kale along with the fresh lemon juice. Process until the mixture is well combined and begins to look like a thick paste.

Oil and pasta water added to pesto and processed.

Step 4: Emulsify the Pesto with Olive Oil. With the food processor running, slowly drizzle in the extra virgin olive oil through the feed tube. Continue processing until the pesto is blended to a smooth, emulsified consistency. This slow addition is key to achieving a stable and creamy pesto. Set this rich, green pesto aside while you prepare the rest of your components.

Step 5: Prepare Your Pasta (Simultaneously for Efficiency). It’s time to get your pasta cooking. Bring a second large pot of generously salted water to a rolling boil. Add your preferred pasta shape and cook according to package directions until it reaches a perfect al dente state. Remember to reserve some of the starchy pasta water before draining!

Frying sausage in a saucepan.

Step 6: Cook the Sweet Italian Sausage. In a large saucepan or deep skillet, heat to medium-high. Add the sweet Italian sausage, breaking it apart with a wooden spoon as it cooks. Allow it to brown and crisp slightly for enhanced flavor. Once fully cooked, drain any excess fat from the pan. Keep the sausage in the pan, ready to combine with the pasta.

Boiling pasta.

Step 7: Boil Pasta to Al Dente. While the sausage cooks, ensure your large pot of water for the pasta is boiling vigorously. Salt the water generously, as this is your only chance to season the pasta from within. Add your chosen pasta shape and cook until it is perfectly al dente, meaning it’s firm to the bite. This usually takes about 8-10 minutes depending on the pasta. Don’t overcook!

Straining kale pesto in a mesh strainer.

Step 8: Achieve Unbeatable Creaminess by Straining the Pesto. This is the crucial step for that signature creamy texture! Take your processed kale pesto and pour it into a fine mesh strainer set over a bowl. Using the back of a spoon or a spatula, press down firmly on the pesto, straining out all the liquid and leaving behind the fibrous kale pulp (the “ruffage”). Squeeze out as much liquid as possible, ensuring you extract every drop of that flavorful, smooth green essence. Discard the solids. Now, to the strained liquid, add the grated Parmigiano-Reggiano and whisk vigorously until thoroughly combined and smooth. This step prevents any grainy texture and ensures a truly luxurious sauce.

Step 9: Combine and Thicken for a Luxurious Sauce. Once your pasta is al dente, drain it, reserving at least ½ cup of the starchy pasta water. Add the drained pasta directly to the saucepan with the cooked sausage. Pour in ½ cup of the reserved pasta water. Mix well, then stir in your beautifully strained and whisked kale pesto. Continue to mix the pasta, sausage, and pesto together over medium-low heat. Keep stirring for approximately 5-8 minutes, allowing the sauce to gently emulsify and thicken, clinging perfectly to the pasta. The starches from the pasta water, combined with the Parmigiano in the pesto, will create an incredibly creamy, cohesive sauce. Finally, grate in a generous extra portion of Parmigiano-Reggiano and combine well for an added layer of flavor and richness.

Serve your exquisite Kale Walnut Pesto Pasta immediately, garnished with a sprinkle of freshly chopped walnuts and more grated Parmigiana for an extra touch of elegance and flavor. This dish is hearty enough to stand alone, but it also pairs wonderfully with complementary proteins like our Cast Iron Boneless Pork Chops or a refined Restaurant-Style Chicken Saltimbocca. Enjoy the vibrant flavors and comforting warmth of this winter pasta masterpiece!

Pro-Tips for Pesto Pasta Perfection

Achieve truly restaurant-quality results with these expert tips:

  1. Master the Blanching Technique for Kale. Blanching the kale is a two-fold genius move. Firstly, it tenderizes the kale, making it easier to process into a smooth pesto. Secondly, and perhaps more importantly, the quick dip in boiling water followed by an immediate ice bath locks in the kale’s vivid green color. This ensures your pesto is not only delicious but also visually stunning and appealing, without any dullness that can sometimes occur with raw kale.
  2. Embrace the Power of Straining Your Pesto. This is the game-changing secret to the unparalleled creaminess of this dish. While traditional pestos often boast a more rustic, textured consistency, straining the kale pesto through a fine mesh strainer meticulously removes all the fibrous plant material. What remains is a concentrated, smooth, and flavorful liquid that carries the essence of kale and walnuts without any “ruffage” that could detract from the silky mouthfeel. You can certainly skip this step if you prefer a more traditional, textured pesto, but for that luxurious, velvety sauce, straining is non-negotiable. A cheesecloth can also be used as an alternative.
  3. Perfect the Sausage Break-Up. The size and texture of your sausage pieces are crucial to how they integrate with the smooth pesto. Breaking the sausage into small, uniform pieces with a wooden spoon while it cooks ensures that each bite of pasta has a balanced distribution of savory sausage. These smaller pieces blend harmoniously with the very smooth pesto, rather than creating large, chunky contrasts that could disrupt the overall creamy experience.
  4. Season Strategically with Parmesan. When it comes to salting, timing is everything. Add the Parmigiano-Reggiano to the *strained* pesto, rather than before. This allows you to accurately taste and adjust the salt levels without the interference of kale fibers. The Parmesan not only contributes its characteristic salty, umami flavor but also aids in emulsification, bringing out the bright, nutty notes of the pesto and ensuring a well-seasoned, vibrant sauce.
  5. Cook the Pesto with the Pasta for Ultimate Creaminess. Don’t just toss the pesto with hot pasta; allow them to cook together briefly. The magical interaction between the starches released from the pasta (especially with the addition of reserved pasta water) and the fats in the pesto, along with the Parmigiano, creates a natural emulsion. Cooking the sauce on medium-low heat for 5-8 minutes lets it gently thicken, transforming into a rich, glossy coating that adheres beautifully to every strand of pasta, delivering an intensely creamy and satisfying finish.

Frequently Asked Questions About Kale Walnut Pesto Pasta

Here are some common questions to help you perfect this delicious dish:

Is it absolutely necessary to strain the pesto?

While not strictly mandatory, straining the pesto is the key to achieving the exceptionally creamy and smooth texture that defines this particular recipe. Without straining, you’ll have a more rustic, slightly fibrous pesto. If you don’t have a fine mesh strainer, a cheesecloth can also be used for straining.

What if my pesto sauce appears too thin after combining everything?

Don’t worry if your sauce seems a bit thin initially. The magic happens as it cooks with the pasta and sausage. Continue to gently cook the mixture over a medium-low heat. The starches from the pasta water and the melting Parmesan will work together to thicken the sauce considerably, making it richer and creamier. Just give it a few more minutes, stirring often.

How can I ensure I add the right amount of salt to my pesto?

The best way to season your pesto perfectly is to taste as you go. After straining the pesto and adding the Parmigiano-Reggiano, taste a small spoonful. Since Parmigiano adds significant saltiness, you can then add additional kosher salt in small increments until the flavor is bright and balanced to your liking.

Can I prepare this creamy kale walnut pesto pasta without the sausage?

Absolutely! The sausage adds a wonderful heartiness and savory depth, but it is entirely optional. If you’re aiming for a lighter, vegetarian dish, or simply prefer to let the creamy kale walnut pesto take center stage, feel free to omit the sausage. The pasta will still be incredibly delicious and satisfying.

What type of pasta works best with this pesto?

Shell pasta is featured in our images, and its curves are great for catching the creamy sauce. However, any pasta shape that holds sauce well, like fusilli, orecchiette, or even a classic spaghetti or fettuccine, would be delightful. Choose your favorite shape!

How can I store leftover pesto or the finished pasta dish?

Leftover pesto can be stored in an airtight container in the refrigerator for up to 5 days, topped with a thin layer of olive oil to prevent oxidation. The finished pasta dish, if sealed properly, can be refrigerated for 2-3 days. Reheat gently on the stovetop with a splash of water or broth to loosen the sauce.

Equipment

  • 1 food processor
  • 1 large saucepan
  • 1 large pot
  • 1 large bowl
  • 1 mesh strainer

Ingredients

  

  • ½ lb pasta
  • ½ lb sweet Italian sausage
  • 1 head lacinato kale
  • ½ cup extra virgin olive oil
  • ¼ cup walnuts
  • 2 cloves garlic
  • 1 teaspoon kosher salt
  • 6 basil leaves
  • ½ cup parmigiana plus extra for serving
  • 2 tablespoon lemon juice

Instructions

 

  • Prepare the kale by removing the stems. Grab the thickest part of the kale stem between your thumb and forefinger. Create a tight circle with your opposite thumb and forefinger around the kale and pull off the leaves.
  • Bring a large pot of water to a boil. Salt the water. Boil the kale for 30 seconds, using tongs to turn often. Remove the kale and place it directly into a large bowl of ice. Turn the kale until it is cooled. Then, squeeze the water out of the kale and set it aside on a plate.
  • In a food processor, combine walnuts, garlic, and salt. Process until walnuts are ground. Then add the kale and lemon juice. Start the processor and slowly drizzle the olive oil into the processor until it is blended smooth. Set aside.
  • In a large saucepan, raise the heat to medium. Add the sausage and let it sit for a few minutes undisturbed until it begins to sear. Then use a wooden spoon to break apart the sausage into small pieces.
  • While searing the sausage, bring a large pot of water to a boil. Salt the water and add the pasta. Boil until al dente.
  • Halfway through boiling the pasta, ladle ½ cup of pasta water into the processor. Blend until combined. Then, pour the pesto into a mesh strainer to strain out all of the kale leaves. Strain the pesto into a bowl squeezing out as much of the liquid as possible. Then add the parmesan and whisk together.
  • Strain the pasta and add it to the sausage along with ½ cup of pasta water. Mix well. Then stir in the strained kale pesto. Mix the pasta, sausage, and pesto together well over medium-low heat until the pesto begins to thicken. It should take about 5-8 minutes. Grate in extra parmesan and combine well.
  • Serve pasta with chopped walnuts and parmigiana.

Notes

  1. Blanching the kale will not only tenderize but keep its bright green color for a beautiful pesto dish.
  2. Straining the pesto from the kale gives you all the delicious flavor but removes all of the kale which can really change the texture of this smooth, creamy pesto. You can leave the kale in but it will be a much more rustic pesto pasta with ruffage.
  3. Breaking up the sausage into small pieces with a wooden spoon is important to the texture of the sauce. The small pieces of sausage combine well with a very smooth pesto.
  4. Salting the pesto with the parmesan after straining the pesto will bring out all the bright and nutty flavors in the dish.
  5. Cook the pesto with the pasta and pasta water to make it extra creamy. Cooking it on low for a few minutes will let the sauce thicken up and really coat the pasta.
