Why We Love This Oven Roasted Broccoli and Cauliflower Recipe

This may be an oversimplification, but when it comes to preparing veggies for a simple side dish, I usually rely on one of three rules that always seem to work:

  1. When in doubt, roast them!
  2. Cheese is never a bad idea!
  3. Garlic makes the world go round.

This is one of those Broccoli and Cauliflower Recipes where I have employed not one but two of these tried and true veggie side dish rules (roasting and adding cheese) and the results are amazingly delicious.

Note: If you are hoping for some veggie side dishes with garlic (that follow rule three) you can search through all of the side dishes here. There are tons! Here are a couple of my favorites: Garlic Herb Butternut Squash and this make-ahead Broccoli and Cauliflower Casserole.

In the past I have shared roasted broccoli and roasted cauliflower recipes, but I have never shared one here where they were roasted together on the same sheet pan. So I figured, why not! Then I added on two kinds of cheese and I think from now on the rest will be history!

This simple side dish pairs well with roasted poultry, pork and beef.

Do Broccoli and Cauliflower Go Together?

  • Broccoli and cauliflower cook at roughly the same rate which means they go great in recipes together.
  • Just keep in mind they need to be cut into florets that are roughly the same size and roasted in an even layer.
  • Broccoli and Cauliflower are related, they are both members of the brassica family of plants which means they are cruciferous vegetables. Other members of this family are cabbage and kale.
  • These vegetables are high in antioxidants and vitamins, and may help to prevent cancer.
  • Both vegetables are crisp when raw, and have a balance of sweet and peppery mustard flavor.
  • Note: When cauliflower or broccoli are over cooked they can taste sulfurous.
  • I love to add them to a broccoli and cauliflower casserole or cauliflower macaroni and cheese, but this simple preparation of roasting them together is even easier and I think the best way to prepare them! Roasted Cauliflower and Broccoli Pasta from Two Healthy Kitchens is a way of combining them into a main dish.

Ingredients For Baked Broccoli and Cauliflower

Roasted broccoli and cauliflower with cheese ingredients
  • Fresh Broccoli and Cauliflower Florets – Perfect veggies to roast together because they cook at the same rate and broccoli’s grassy, earthy and slight bitterness complements cauliflower’s sweet nutty flavor.
  • Extra-Virgin Olive Oil – This oil has a smoke point of 450 degrees making it a good choice for roasted vegetables, as it also adds flavor.
  • Kosher Salt and Black Pepper – A delicious combo to enhance the flavor profile of the veggies.
  • Nutmeg and Cayenne – The nutty, sweet warmth of nutmeg and the spicy kick of the cayenne also work to complement and amplify the flavor of the veggies and are two of my favorite seasonings.
  • Cheddar and Parmesan or Romano – The creamy slightly acidic cheddar and the rich nuttiness of the parmesan are delicious with the caramelized flavor of the roasted veggies.

Step By Step Instructions To Make Roasted Broccoli and Cauliflower with Cheese

roasted broccoli and cauliflower with cheese steps 1 and 2

Step 1: Preheat oven and prepare the pan and veggies.

Use a high temperature, 450 degrees is good, to roast broccoli and cauliflower. It will allow it to soften just enough without becoming flabby, and will also brown a bit which gives the broccoli a slightly nutty taste and delicious crispy edges.

Line your cookie sheet with aluminum foil, parchment paper or if you have one a silicone baking mat. That will catch the melted cheese so the clean up will be much easier.

Toss broccoli and cauliflower florets with oil, salt and pepper in a large bowl. And I also liked to add in a generous pinch each of ground nutmeg and cayenne pepper. They go well with the cheese! You can also add in some garlic powder too (see above rules.)

Spread on the prepared baking sheet in a single layer.

Step 2: Roast the veggies.

Roast until the vegetables are browned and softened, about 25 minutes. Once they have softened and browned, then you can add on your cheese! Yay cheese! I used a combo of Vermont Sharp white cheddar and grated Parmesan cheese. Let that melt for about 3 minutes, then you are good to go. Your taste buds will be so happy!

FAQ’s And Expert Tips

Is roasted broccoli good for you?

Yes, because it contains fiber, vitamin C and protein and the olive oil adds beneficial antioxidants.

Do you wash broccoli before roasting?

Wash the broccoli well and make sure to dry very thoroughly by either shaking and patting dry or using a salad spinner. Do not skip the drying because any excess moisture will keep the broccoli from caramelizing and steam it instead.

Do you roast vegetables covered or uncovered?

Roast vegetables uncovered and stir 2-3 times during cooking. Do not cover the vegetables because this will keep them from browning and steam them instead.

Is it okay to roast vegetables with olive oil?

Yes, olive oil is a great option because it stands up well to heat and imparts great flavor.
