Why You’ll Love This Best Pistachio Pesto Recipe
This Pistachio Pesto recipe is a game-changer. It’s a delicious twist on a classic that will have everyone asking for more.
Toasting is Key: Toasting the pistachios before adding them to the pesto is the secret. The heat releases the oils and volatile compounds in the pistachios, creating a deeper, more complex, and aromatic taste. The visual appeal of the lightly golden pistachios also adds to the pesto’s allure.
Quick & Easy: You’ll be amazed at how quickly this pesto comes together. It’s ready in minutes, making it perfect for busy weeknights.
Versatile: This pesto is incredibly versatile. Use it on pasta, pizza, sandwiches, grilled vegetables, or as a dip – the possibilities are endless!
Simple Ingredients: You only need a handful of simple, fresh ingredients to create this flavor explosion.
Ingredients Needed
- 3 cups lightly-packed fresh basil leaves
- 1/2 cup freshly grated Parmesan
- 1/3 cup shelled pistachios
- 3 cloves garlic
- 1 teaspoon sea salt
- 1/2 teaspoon freshly-cracked black pepper
- 1/2 cup extra-virgin olive oil
Ingredient Notes & Substitutions
Pistachios: High-quality pistachios are essential for the best flavor. I recommend sourcing pistachios from California, if possible, for their excellent quality. Shelled pistachios are the most convenient option for this recipe, saving you the hassle of shelling them yourself.
Parmesan: Freshly grated Parmesan cheese is best for both flavor and texture. Pecorino Romano offers a flavorful alternative. For a vegan option, substitute 3-5 tablespoons (to taste) of nutritional yeast in place of the Parmesan to make vegan pesto.
Basil: Fresh basil is key! The quality of your basil directly impacts the final flavor. Feel free to experiment with other herbs like baby arugula, spinach, parsley, or cilantro, either in place of basil or mixed with it. For another great salad option, consider a pesto couscous salad.
Olive Oil: Use high-quality extra virgin olive oil for the best flavor. Look for oils with fruity or peppery notes to enhance the pesto. To understand more about the characteristics of good olive oil, you might find this guide from the Olive Oil Times helpful.
Salt: I prefer sea salt for this recipe, as it enhances the other flavors. Kosher salt also works well.
How to Make Pistachio Pesto
Follow these simple steps to create your own vibrant Pistachio Pesto.
Step 1: Toast the Pistachios
Toast the pistachios in a dry pan over medium heat or in the oven at 350°F (175°C) for 5-10 minutes. You’ll smell a rich, nutty aroma when they’re ready and they should be lightly golden.
Step 2: Combine Ingredients
Add the toasted pistachios, fresh basil leaves, Parmesan cheese, garlic cloves, sea salt, and black pepper to your food processor or blender. Pulse until the ingredients are finely chopped, stopping to scrape down the sides as needed.
Step 3: Add Olive Oil
With the food processor running on low speed, slowly drizzle in the extra virgin olive oil until it is completely combined. Pause the food processor and scrape down the sides to ensure everything is evenly mixed. Pulse again until the mixture is smooth and creamy. If your pesto is too thick, feel free to thin it out with a few tablespoons of extra olive oil or water.
Step 4: Taste and Adjust
Taste the pesto and adjust seasonings as needed. Add more salt and pepper to taste. The biggest mistake people make with pesto is not seasoning it enough, so be sure to taste and add more salt and pepper if needed.
Step 5: Serve or Store
Serve immediately. Or refrigerate in a sealed container for up to 3 days, or freeze for up to 3 months. This pesto is delicious on pasta or pizza, and it is also an excellent dip.
Preventing Browning and Oxidation
Basil can oxidize quickly, causing your pesto to turn brown. This is a natural process, but here are some ways to slow it down.
Blanching the basil: Briefly blanching the basil in boiling water before blending can help preserve its color.
Adding lemon juice: A squeeze of lemon juice adds brightness and helps prevent browning due to its acidity.
Covering with olive oil: To prevent browning and also help the pesto last a bit longer, feel free to pour a thin layer of olive oil on top of the pesto to cover its surface. Or alternatively, you can place a piece of plastic wrap directly on top of the surface of the pesto.
Storing in an airtight container: Minimize air exposure by storing your pesto in an airtight container.
