Roasted Broccoli Pesto Pasta

If the adult version of me could go back and tell my 10-year-old-self that I would grow up to love broccoli, I never would have believed it.

But yes, broccoli is one of the many vegetables, like brussels sprouts, cauliflower and more, that I adore now. I think part of that is because how much cooking and food has evolved over the last so many years, not to date myself.

These once unappealing veggies have become exciting. I don’t want to call them trendy because they have always been here and been delicious when done right.

Now back to broccoli, and pesto and pasta! (And my enthusiasm for this simple vegetarian dinner.)

Roasting Broccoli For Pesto

In general when I roast broccoli, I prefer to keep things more al dente, similar to how I treat pasta. And that’s true even when I am turning that broccoli into sauce.

Good roasted broccoli is bright green and still maintains some of its snap and bite. That’s why its important to let a food processor do the work to chop and puree the florets along with the other ingredients.

You will find that this pesto is filling and chunkier than traditional basil pesto, but it still has everything we all love about this special sauce.

And even better that peak broccoli season is from fall through spring, so it’s around a lot longer and through the colder months unlike more delicate basil.

The Ingredients

You will need these ingredients to make roasted broccoli pasta:

  • Broccoli: When you are choosing broccoli, the florets should be snuggly packed together. Avoid any crowns that show yellowing because they aren’t as fresh.
  • Penne: My first pick for pasta is penne with ridges, so the chunky pesto will really cling to the noodles.
  • Pine nuts: Make sure to toast the pine nuts before you add them to the pesto. You can do this in the oven on a sheet pan at 350 degrees F for about 5 minutes. Just make sure to watch the nuts, so they don’t get too dark.
  • Garlic: You can’t have pesto without a little garlic!
  • Parmesan: Just like a classic pesto, this one has Parmesan cheese.
  • Lemon: The juice of a lemon adds brightness to the roasted broccoli.
  • Olive oil Definitely use extra virgin olive oil.
  • Salt & pepper: The broccoli should be seasoned when it’s roasted and then the pesto needs salt and pepper too.

How To Make Roasted Broccoli Pesto

  1. Roast the broccoli. Toss the florets on a sheet pan with olive oil, salt and pepper. The broccoli is ready when it is tender and just starting to brown at the edges. Save a half-cup of broccoli to stir into the pasta.
  2. Make the pesto. Mince a garlic clove in a food processor. Then add the roasted broccoli, pine nuts, Parmesan, lemon juice, salt and pepper. Chop the mixture and pour in the olive oil through the feeder tube with the motor running.
  3. Cook the pasta until al dente. Use a slotted spoon to transfer the pasta to a big bowl.
  4. Stir the sauce into the pasta with the reserved roasted broccoli.
  5. Top with grated Parmesan before serving.

How To Serve Roasted Broccoli Pasta

Ready in less than 30 minutes, I think of this broccoli pasta as a busy weeknight vegetarian dinner.

If you want dinner on the table even quicker, you can make the pesto no more than 3 days in advance. Just warm it over low heat in a large saucepan and stir in the cooked pasta.
