Instead of basil, we use broccoli as the base of this broccoli pesto pasta recipe, but it is still made with some basil, as well as toasted walnuts like a classic pesto.
If you don't have a food processor, you can still make this sauce. After all, Italian grandmothers back in the day didn't have one either. You can either use a mortar and pestle to crush down the ingredients in batches, or finely chop it all up by hand.
Food processor or not, the secret to the vibrant color of this broccoli pesto is blanching the broccoli. Don't skip transferring the cooked broccoli from the boiling water to an ice bath; it stops the cooking process and will preserve the vegetable's bright green color.
Learn how to make broccoli pesto pasta. While delicious served warm out of the skillet, this dish can also be eaten as a cold pasta salad for lunch.

Prepare the dish up to two days ahead, then cool, cover, or transfer to an airtight container. When you're ready to serve, you can reheat on the stovetop until hot throughout, adding a splash of water or broth if needed to loosen the texture.

Leftover broccoli pesto pasta can be stored in an airtight container in the refrigerator for up to four days, or frozen for up to three months. Thaw overnight in the refrigerator if frozen before reheating. Reheat in the microwave or on the stovetop, adding a splash of water or broth if needed to adjust the consistency. You can also enjoy the leftovers cold, especially if bringing to a picnic or as a quick lunch item on a hot summer day.
