How to Make Roasted Broccoli and Cauliflower

  1. Prepare for roasting: Preheat the oven to 425 degrees Fahrenheit and set out a large rimmed sheet pan. You can use parchment paper, but roasting directly on the pan (or on aluminum foil) will create the most crispy texture.
  2. Prepare and season vegetables: Chop the vegetables and add them to a large bowl. In a separate bowl, stir together lemon juice, olive oil and seasonings. Pour into the bowl with the chopped vegetables and stir until the vegetables are fully coated.
  3. Assemble on a sheet pan: Spread veggies out on a large baking sheet making sure they are in one layer. If using, add lemon slices and grated Parmesan cheese on top.
  4. Roast the vegetables: Cook in the preheated oven for 15 to 20 minutes, until the vegetables are fork tender and begin to brown on the edges. Serve immediately.

If you want extra crispy vegetables, broil them for 1 to 2 minutes at the end of the cooking time.

Expert Tips

  1. Cut the vegetables to roughly the same size. This ensures that they are all finished cooking at the same time.
  2. Layer the vegetables in a thin layer on the sheet pan. No overlapping. This will prevent them from steaming which will make them crispy.
  3. Use two smaller sheet pans instead of one large one, if needed. This helps to prevent overcrowding to ensure even roasting.
  4. Looking for a vegan version? Omit the cheese and use a sprinkle of nutritional yeast instead.

  1. That was delicious. Lemon and garlic uplifted the overall flavor. My family loved it. I will make this recipe again soon. Thanks!

  2. Yumm! I love broccoli but I never know what to do with cauliflower. This is a perfect combo!

  3. Amazing flavor! My kids never want to eat any kind of vegetables plain so I’m always looking for ways to spice them up and this is probably my new favorite recipe. Thank you so much!

  4. I added chicken breast pieces to mine, and followed the recipe perfectly. It was absolutely delicious. I served with wild rice, but next time I think I’ll double the sauce and cook pasta and toss it all together with the extra sauce.  Delicious, thanks for this great recipe I see myself using in so many different ways!
