Ingredients and substitution notes 

  • Broccoli. Fresh broccoli is the main ingredient in this recipe, but you can substitute it with other cruciferous vegetables such as cauliflower or Brussels sprouts.
  • Basil. Fresh basil leaves are a key ingredient in pesto sauce. You can substitute it with other fresh herbs such as parsley, cilantro, or mint.
  • Spinach. Fresh spinach leaves are a great addition to pesto sauce, but you can substitute it with other leafy greens such as kale, arugula, or collard greens.
  • Pine nuts. Pine nuts are a traditional ingredient in pesto sauce, but you can substitute them with other nuts such as almonds, walnuts, or cashews.
  • Garlic. Fresh garlic adds a pungent and aromatic flavor to pesto sauce. You can substitute it with garlic powder.
  • Crushed red pepper. Adds a spicy kick to the pesto sauce. You can adjust the amount of crushed red pepper to your liking or omit it entirely.
  • Nutritional yeast flakes. Nutritional yeast flakes add a cheesy and nutty flavor to the pesto sauce.
  • Lemon juice. Adds acidity and brightness to the pesto sauce. You can substitute it with other citrus juices such as lime.
  • Salt. Enhances the flavor of the pesto sauce. You can adjust the amount of salt to your liking or use a low-sodium alternative.
  • Olive oil. Extra-virgin olive oil is the preferred oil for pesto sauce, but you can substitute it with other oils such as avocado oil or sunflower oil.
  • Use fresh broccoli: Fresh broccoli will roast more evenly and have a better flavor than frozen broccoli. Look for broccoli with tight, dark green florets and firm stems.
  • Cut the broccoli into even-sized florets: Cut the broccoli into evenly sized florets to ensure that they roast evenly.
  • Roast the broccoli until tender and crispy: Roast the broccoli for 20-25 minutes, or until the florets are tender and lightly browned on the outside. Check the broccoli regularly to ensure that it doesn’t burn.
  • Add extra ingredients as desired: Don’t be afraid to experiment with different ingredients and add-ins to customize the recipe to your liking.
  • Serve immediately: Serve the roasted pesto broccoli immediately after tossing it with the sauce to ensure that it stays warm and crispy.

Make ahead of instructions and storage

Freeze the Pesto Sauce:

If you have extra pesto sauce, you can freeze it in an airtight container or freezer bag for up to 3 months. Thaw the sauce in the refrigerator overnight before using.

Don’t freeze the roasted broccoli: Roasted broccoli doesn’t freeze well and can become mushy when thawed.

FAQs

Can I make the pesto sauce without nutritional yeast flakes? 

Yes, you can omit the nutritional yeast flakes if you don’t have them or if you don’t like the flavor. The nutritional yeast flakes add a cheesy and nutty flavor to the sauce, but it will still taste delicious without it.

Can I use a different type of nut instead of pine nuts? 

Yes, you can use any type of nuts you prefer, such as walnuts, almonds, or cashews. They will add a different flavor and texture to the pesto sauce, but it will still be delicious.

Can I use frozen broccoli instead of fresh broccoli? 

While fresh broccoli is recommended for this recipe, you can use frozen broccoli if that’s all you have on hand. However, keep in mind that frozen broccoli may become more watery and not roast as evenly as fresh broccoli.  If using frozen broccoli, thaw it completely and pat it dry with paper towels before roasting.
