No Funny Business—Just Delicious Roasted Broccoli (that Kids Will Actually Eat.)

We're not necessarily in favor of "sneaking" vegetables into our kids' dinners (although we're not above it, either). Our perpetual goal is to present vegetables to our families in a way that makes them appealing, whatever that entails! And sometimes—when making this broccoli pesto, for example—that means blending the vegetable with herbs, garlic, Parmesan cheese and rivers of golden olive oil. Who wouldn’t want to eat that?

Broccoli Pesto is Five-Ingredient Perfection.

We love the robust flavors of broccoli pesto—it’s the ideal pasta sauce for this liminal moment, when we linger between summer and the start of fall. Basil hints at fresh summer breezes, while roasted broccoli florets root it firmly in the harvest season. Here’s what you’ll need to make this broccoli pesto recipe:

  • Garlic. Always and forever.
  • Broccoli, roughly chopped.
  • Fresh basil.
  • Parmigiano-Reggiano cheese. Yes, you could use pre-grated, but freshly grated will always taste just a little better.
  • Extra virgin olive oil. Pesto is the perfect example of the right moment to use extra virgin olive oil! All of those unctuous, peppery, buttery flavors will sing through the pesto and give it oomph.

The Best Nut-Free Pesto Recipe Ever.

While classic pesto relies on pine nuts for heft and a mildly bitter, toasty note, our broccoli pesto recipe gets all of those same flavors from roasted broccoli! Drizzled with olive oil and roasted until crisp and wilty-tender, broccoli becomes positively addictive. That tell-tale slightly bitter flavor that defines most cruciferous vegetables mellows out and gives way to roasty, deeply flavorful vibrancy. It serves as the backbone of this non-traditional—but no less delightful—pesto sauce recipe.

How To Make Broccoli Pesto

Some broccoli pesto recipes call for steamed broccoli, but we’re not messing around here! Since the broccoli needs to stand in for pine nuts in our nut free pesto recipe, we roast it to give loads of extra flavor. Ready, set, go!

  1. Roast the broccoli at 400°F for 30 minutes, or until it’s lovely and crispy, but before it’s burnt. (Note! If you’re making this broccoli pesto sauce to go with our Baked Chicken Meatballs, and opt to roast the broccoli while you bake the meatballs, you might need to adjust the heat a little. That will change the roasting time a bit, so just keep an eye on the broccoli—taste a floret occasionally, and pull it when it’s done.)
  2. Purée the roasted broccoli, Parmigiano-Reggiano cheese, olive oil, basil and garlic in a food processor or blender (either countertop or immersion blender) until you achieve a consistency you’re happy with. Some people prefer their pesto a little chunkier—traditionally made into a paste using a mortar and pestle, pesto isn’t meant to be silky smooth.
  3. Eat! We love to eat roasted broccoli pesto with bucatini pasta and chicken meatballs, but you can also use it anywhere you’d use regular pesto sauce!
