Broccoli Walnut Pesto Pasta is a fresh, flavorful twist on traditional pesto. Tender broccoli blends with toasted walnuts, garlic, Parmesan, and olive oil to create a creamy, nutty sauce that coats every bite of pasta.

Inspired by classic Pesto alla Genovese but made without pine nuts, this version offers a budget-friendly and equally delicious alternative. Ready in under 30 minutes, it’s a simple vegetarian dinner that’s vibrant, satisfying, and perfect for busy weeknights.

OMGushhhhh!! This is so INCREDIBLY delicious! I couldn’t stop eating spoonfuls out of the blender. We’re using it on Trader Joe’s Cauliflower Gnocchi to increase the veg content. I’m literally counting the minutes until I can make dinner. This delicious, healthy pesto is just sitting here calling my name. THANK YOU!!

There is one extra step in that you need to cook the broccoli first, but the great part is that we’re using that already boiling broccoli cooking liquid to then boil our pasta. Meaning less cleanup, and less time to bring two huge pots of water to a boil.
I think you’re going to love this dish. Especially if you love pesto, but you’re ready to try something a little different flavor wise.
I’m topping it all off with some delicious, crunchy walnuts to make this dish extra delicious and add a heart healthy boost.

How to make it
- Boil the broccoli until just tender.
- If you’re serving the pesto with pasta, remove the broccoli with a slotted spoon and save the boiling water in the pot. Then, add the pasta to the boiling broccoli water and cook to al dente. Reserve some of the pasta cooking water before draining.
- Combine the cooked broccoli with parmesan, basil, garlic, olive oil & lemon juice in a food processor or blender. Process until smooth, scraping the sides of the food processor as needed.
- If desired, toss the pasta with the broccoli pesto, adding reserved pasta cooking liquid as needed to coat evenly.
