Key Ingredients for Creamy 5 Ingredient Pistachio Pesto Pasta

See recipe card below for full list of measurements, ingredients, and instructions.

Pistachios

These vibrant green nuts are the star of the show, lending a unique sweetness and rich, buttery depth to the pesto. For best results, use shelled, unsalted pistachios so you can control the saltiness. If you're in a pinch, roasted pistachios work too—just skip any with added flavors. Can't find pistachios? Try cashews for a similar creamy texture or classic pine nuts for a different nuance.

Fresh Basil

Basil gives the pesto its iconic herbal aroma and refreshing flavor. Always opt for fresh basil leaves, avoiding dried or wilted stems for the brightest, punchiest taste. If you're feeling adventurous, a mix of basil and baby spinach keeps the sauce green and vibrant, especially when basil is scarce.

Parmesan Cheese

Parmesan provides a savory kick and helps the pesto cling to every strand of pasta. Grate your own for the best flavor and creaminess. For a vegetarian option, use a vegetarian hard cheese or nutritional yeast for a nutty, cheesy vibe.

Olive Oil

A good drizzle of extra-virgin olive oil brings richness and marries all the flavors together. Choose a fruity, high-quality oil for the best taste. If needed, a neutral oil like avocado will work in a pinch, though you'll miss some of the signature peppery notes olive oil provides.

Pasta

Short or long cut pasta both excel here—penne, rigatoni, spaghetti, or linguine all deliver. Pick your favorite based on what you have on hand! For gluten-free needs, use a chickpea or brown rice pasta and cook accordingly.

Instructions for Creamy 5 Ingredient Pistachio Pesto Pasta

See recipe card below for full list of measurements, ingredients, and instructions.

Boil Your Pasta

Bring a large pot of salted water to a rolling boil. Add the pasta and cook just until al dente, according to package directions. Before draining, scoop out at least one cup of pasta water for the sauce—this starchy magic will make everything creamy.

Make the Pistachio Pesto

While the pasta cooks, add pistachios, basil, Parmesan, and 1/2 teaspoon salt to a food processor. Pulse several times until the nuts are finely chopped. With the motor running, slowly stream in the olive oil and a few tablespoons of pasta water, blending until smooth and creamy. If it’s too thick, add a splash more pasta water.

Toss It All Together

Return the drained pasta to the pot. Pour the pesto over the pasta and toss vigorously, adding reserved pasta water a bit at a time until every noodle is glossy and coated. Taste and adjust seasoning with extra salt and black pepper.

Serve and Garnish

Swirl the creamy pasta onto plates or bowls. Top generously with extra Parmesan, more chopped pistachios, and a sprinkle of black pepper. Serve immediately while warm and luscious!

Recipe Variations

Make It Vegan

Swap out the Parmesan for nutritional yeast or your favorite plant-based hard cheese. The pesto stays ultra-creamy with the pistachio base, so you won't miss a thing!

Add Some Citrus Zing

Try blending in the zest of one lemon or a squeeze of juice for a bright, sunny twist. It accentuates the herby flavors and adds a refreshing pop.

Boost the Greens

Mix in a handful of baby spinach, arugula, or even fresh parsley with the basil for a different green pesto flavor. This is a great way to use up leftover greens and add extra nutrients.

Go Gluten-Free

Simply choose your favorite gluten-free pasta, such as brown rice or chickpea. Cook carefully according to package directions, since gluten-free pasta is often more delicate.

Amp It Up With Garlic

For a little extra punch, add a clove of fresh garlic or a sprinkle of garlic powder to the pesto before blending.

Serving Suggestions

For a complete Italian-inspired meal, serve your Creamy 5 Ingredient Pistachio Pesto Pasta with a crisp arugula salad, roasted cherry tomatoes, or grilled vegetables. Top each serving with a shower of Parmesan, extra chopped pistachios, and a few fresh basil leaves for garnish. If you're looking for added protein, pair with grilled chicken, shrimp, or chickpeas on the side.

Storage and Reheating

Store leftover pasta in an airtight container in the refrigerator for up to 3 days. To reheat, add a splash of water or milk to loosen the sauce and gently warm in a skillet over low heat, stirring frequently. The pesto sauce can also be made ahead and stored separately for 4-5 days. For best texture, avoid freezing finished pasta, but the pesto itself can be frozen in a container for up to one month—thaw before tossing with hot pasta.
