1-First, gather all the ingredients: 3 cups lightly-packed fresh basil leaves, 1/2 cup freshly grated Parmesan cheese, 1/3 cup shelled pistachios, 3 cloves garlic, 1 teaspoon sea salt, 1/2 teaspoon freshly cracked black pepper, and 1/2 cup extra-virgin olive oil. Make sure the basil is washed and dried to keep the flavors bright.

2-Next, add the pistachios, basil leaves, and garlic to a food processor. Pulse a few times until they’re coarsely chopped, which helps release those wonderful nutty and herbal notes.

3-Then, toss in the Parmesan cheese, sea salt, and black pepper. Blend again to mix everything evenly, creating a base that’s full of flavor and texture.

4-With the processor running, slowly pour in the extra-virgin olive oil until the mixture smooths out to your liking. This step binds it all together and gives that classic pesto consistency.

5-Finally, taste your pesto and adjust if needed, maybe adding a bit more salt or a splash of something fresh. Serve it right away or store it for later use in salads or other dishes.
