• Fresh Basil - Sweet, peppery basil adds an oomph of flavor to the pesto while also contributing to the bright green color of the sauce.

• Parmesan Cheese (grated) - Salty, sharp, and tangy parmesan adds umami and texture to the pesto.
• Extra-Virgin Olive Oil - Use the good stuff; pesto is a raw sauce, so the quality of ingredients is essential.
• Garlic (peeled and roughly chopped)
• Lemon Juice & Zest - Every sauce needs an acidic element. Fresh lemon juice and zest assist in the pesto's vibrant flavor and help keep it green.
• Salt
• Ground Black Pepper

How to Make Spinach Pesto Pasta

Expert Tips

1. Once the water is boiling, generously salt it before adding the pasta.
2. Reserve ¼ cup of the starchy pasta water and add it to the pasta when mixing everything together—this will give the pasta an even creamier texture. Add a little bit of water at a time until the desired creaminess has been reached.
3. After washing the basil leaves, toss them in the salad spinner to dry them quickly.
4. Pesto is freezable and great for make-ahead meals. Double or triple the recipe (not including the pasta) and freeze pesto in freezer-safe containers.
