Why We Love this Recipe

Broccoli and cauliflower are a perfect pair, even better with garlic.

Oven-roasting because it frees you up to prepare other parts of the meal and is great to cook alongside roasted meats.

This dish uses simple ingredients, a splash of oil, garlic, and a few sprinkles of Parmesan cheese! Healthy veggies are on the table in no time.

Ingredients & Variations

This recipe is super simple, and only uses a handful of ingredients!

VEGGIES I used fresh broccoli and cauliflower florets, feel free to add in your favorites like bell peppers or zucchini. Frozen vegetables can be used (more below) but require a different prep.

SEASONINGS Olive oil, minced garlic & parmesan cheese. Feel free to flavor as you’d like… taco seasoning, ranch seasoning, or even Greek seasoning for a flavorful twist!

How to Roast Frozen Broccoli or Cauliflower

Frozen veggies release water as they defrost so be sure to thaw them before cooking. They’ll naturally be softer and won’t have the same tender-crisp texture as fresh vegetables.

  • Season frozen vegetables per recipe below.
  • Roast 12 minutes.
  • Turn oven on to broil and broil 5-7 minutes or until veggies have a bit of color.

How to Roast Broccoli and Cauliflower

Everyone loves an easy and super tasty dish that’s ready in a flash like this one!

  1. Rinse and pat dry broccoli and cauliflower. Cut pieces into uniform sizes.
  2. Toss pieces in oil and minced garlic. Pat shredded Parmesan into crevices of the veggies and bake until tender and lightly browned.
  3. Serve fresh out of the oven or let them cool and serve as a cold snack for dipping!

How to Store Roasted Broccoli and Cauliflower

  • Keep roasted veggies in an airtight container in the refrigerator where they’ll stay fresh for up to 4 days.
  • Crisp them up again by placing them on a baking sheet and putting them under the broiler or in the toaster oven for about 5 minutes.
  • Refresh the flavors with a little salt and pepper and serve again plain or with dipping sauce!
  • Or, add leftovers to casseroles or soups for extra flavor.

  1. tried this recipe and love it. so easy to make and family wants to have this again and again. thanks for sharing.5 stars

  2. The family that used to only like brocolli and cauliflower almost raw or raw – LOVES this recipe.
    I had some that was past its prime and this recipe totally disguised a bit of wilt.
    Very versatile
    It is a staple – tasted great in quick fix pasta bakes, ramen, soup..reheats very well5 stars

  3. Fantastic!! I used less than the amount of veggies and a little more of the olive oil, garlic, and cheese. That gave plenty of room for them to properly roast in my small oven. Very easy. Very tasty. Left-overs? Forget it. There won’t be any.5 stars

  4. Oven temperature and length of roasting are left out. I am reading the instructions, not watching a video. I see that someone says this info is in Step 1, but it is not.3 stars

    1. It’s in step 1 (this recipe doesn’t have a specific video). If you use the jump to recipe button at the top of the post, it will take you directly to the recipe.

      1. Preheat oven to 450°F.

  5. Holly, I have made this twice for my family. We love garlic so I use four minced cloves for four servings. I have not added the parm cheese yet…next time. Excellent recipe.5 stars

  6. Loved this. It was savage. Easy and quick to make and so tasty. I roasted the garlic in the oil and then removed it before tossing veggies in the oil. The few small additions made a standard veggie side into a whopper. Thank you5 stars

  7. I notice on many recipes either the temperature of the oven or time is missing. No temperature for this one and it looks good. I’ll try 4004 stars

  8. This was delicious! My husband told me he didn’t want any vegetables with dinner, so I made this just for me because he does not like broccoli or cauliflower. However, he took one look at it, tried it, and loved it! I will certainly make it again, maybe even this week.
