Ingredient Notes
You just need a few ingredients to make this creamy broccoli pesto pasta!
Pasta - You can use any noodles you prefer for this broccoli pesto pasta! My favorite is rigatoni because it holds a lot of sauce, but you can also use penne, shells, whatever short pasta you prefer!
Broccoli - You need fresh broccoli so that you can use the broccoli stems to make the pesto! However, in a pinch frozen steamed broccoli also works!
Spinach - Fresh spinach helps make up the bulk of the broccoli pesto sauce, but you could also substitute fresh arugula for a more peppery flavor.
Parmesan Cheese - You can substitute your favorite hard Italian cheese. I always use Pecorino Romano instead if I have it on hand.
Pine Nuts - Toasted pine nuts have a soft, almost buttery flavor with a little bit of crunch that makes them a perfect addition to this broccoli pesto pasta! They add a creaminess to the pesto sauce, but I also love garnishing the pasta with extra pine nuts.
Olive Oil - Make sure you use high quality, cold pressed extra virgin olive oil for the best flavor!
Lemon Juice - You need just a little bit of fresh lemon zest and juice to add some brightness to the broccoli stem pasta sauce!
The complete list of ingredients and amounts is located in the recipe card below.
Additions & Substitutions
This broccoli pesto pasta is delicious as is, but you can add in extra protein or veggies if desired!

- Substitute arugula for the spinach
How to Make Broccoli Pesto Pasta
Cook the pasta according to package directions. Make sure you heavily salt the water and cook the pasta for about 1-2 minutes less than the listed time for perfect al dente pasta! Before draining, scoop out about ½ cup of the starchy pasta water and set aside. Then drain the pasta (but do NOT rinse it).
While the pasta is cooking, start on the sauce.
Cut the broccoli florets into bite sized pieces and set aside. Then roughly chop about 1 cup of the remaining broccoli stems.
While the pasta is cooking, you can steam the broccoli over the boiling pasta for 2-3 minutes. Or you can add the broccoli florets to the boiling water with the pasta for the last 2-3 minutes of cooking time.
In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Add in the diced shallots, diced broccoli stems, and garlic and cook for 5-10 minutes, or until the broccoli stems are tender.
Add the sautéed broccoli stems to a blender or food processor along with the shredded parmesan, fresh spinach, fresh basil, pine nuts, olive oil, lemon juice, lemon zest, salt, and pepper.
Then blend until smooth. If the broccoli pesto is too thick, slowly add in about ¼ cup of reserved pasta water. If desired, you can also blend the cooked broccoli florets into the sauce, you'll just need a little extra pasta water to loosen the sauce. Taste and adjust seasonings as needed.
Toss the cooked pasta and steamed broccoli with the broccoli pesto sauce. Garnish with more shredded parmesan and toasted pine nuts and enjoy!
Recipe FAQ's
This pasta is best eaten the same day but will keep in an airtight container in the fridge for up to 3 days. The pasta will soak up the sauce in the fridge, so it's best to reheat on the stove with a little extra water to add more moisture.
Typically it depends on the course. For a light lunch or side dish, typically 2 ounces (55g) per person. For a main course more like 3.5 ounces (100 grams). This broccoli pesto recipe is written for 16 ounces of pasta (1 package) which is 4 large servings or 8 small servings.
Tips for Success!
For best results I always recommend using weight measurements (especially when baking) because it's the most accurate. Kitchen scales are super affordable and also reduce the number of dishes you have to do! However, all my recipes also include US customary measurements for convince. Use this chart to convert measurements for common ingredients!
Substitutions: In all my recipes, I've included substitutions that I know will work, but I cannot guarantee results if you substitute ingredients that I have not recommended. [For example, granulated sugar and honey are indeed both sweeteners but they have very different properties so they can not always be swapped 1:1. Using honey in a cookie recipe that calls for granulated sugar will yield a giant mess.] In the recipe card you'll find links to the specific ingredients/brands that I use.
A note on salt: I almost exclusively use Diamond Crystal Kosher Salt because it's the best all-purpose salt for cooking and baking. If you're not using kosher salt, consult this handy guide for a conversion chart! When in doubt, if you're using table salt just reduce the amount by half for baked goods. When cooking, I prefer to under-salt because you can always add more! If you've over-salted, adding a little bit of acid (like lemon juice) can help.
