We love quick veggie side dishes in our house and this one is no exception. It’s easy to customize and change up, making your roasted broccoli and cauliflower with Parmesan or even a little lemon. Broccoli and cauliflower are very easy to cook together, making this a regular side dish in our house, especially when we are eating pasta and the best Italian meatballs.

Reader Review

Oh my gosh, people!!! This is by far the BEST roasted veggie recipe that I’ve tried—and I promise you, I have tried soooo many!

How to Make Roasted Broccoli and Cauliflower

Here is a brief overview of how this broccoli and cauliflower recipe comes together. Be sure to scroll to the recipe card at the bottom of the post for the full recipe, including all measurements.

  1. Cut your broccoli and cauliflower into small bite-sized pieces. My kiddos don’t like the stems of the broccoli, so I cut those off and eat them raw while I’m cooking, but you can also throw them away. Line a rimmed baking sheet with parchment paper.
  2. Toss the vegetables with oil. If you are only using olive oil and garlic salt, you can toss the vegetables with the other ingredients right on the baking sheet (as seen in the video). If you are using additional ingredients, or if you have really big heads of broccoli and cauliflower, I would recommend tossing the ingredients in a large bowl and then pouring it all onto a baking sheet.
  3. Bake the veggies. I would start checking on it around 30 minutes so you can see how done you want it. I like mine pretty roasted, so I would edge more towards 40 minutes. Enjoy!

Picking out Broccoli

Choose broccoli that is bright green in color. You want to see a similar shade of green throughout the top of the florets. Avoid bunches that have patches of yellow or brown. Look for plump stems and compact florets.

Choosing Cauliflower

When choosing cauliflower for this recipe, pick a head of cauliflower that is bright white and doesn’t have any brown spots. It should have bright green leaves that are tightly attached.

How to Cut Cauliflower and Broccoli

When preparing your broccoli and cauliflower, you can either break it or cut it to break it up into smaller pieces.

  • Cutting the florets: Start by cutting the cauliflower head in half. Working with one half of the head at a time, make two cuts, each angling into the other, to remove the stem from the florets. Then cut the florets into bite-sized pieces.
  • Breaking the florets: The second way you can do this is by breaking florets off the head. Continue to do this until you have broken off all of the pieces away from the stem and broken them into smaller bite-sized pieces.

Adding Parmesan Cheese

Sprinkle some freshly grated Parmesan cheese over the roasted vegetables once it comes out of the oven. It is always best to use a block of Parmesan and grate it fresh rather than using the pre-grated stuff. It will melt and taste so much better.

Cooking Broccoli and Cauliflower in the Air Fryer

You can also let the air fryer do the roasting and cook the veggies in your air fryer. Prepare them the same way and cook them in your air fryer preheated to 400 degrees Fahrenheit, for 15 to 20 minutes, tossing halfway through.

Storing and Reheating Leftovers

Store any leftover roasted cauliflower and broccoli in an airtight container in the refrigerator for up to three days. Reheat only the portion you plan to eat in the air fryer, microwave, or oven until heated through.

    I make these veggies often too. Sometimes I toss with Sweet thai Chile sauce, add onions, mushrooms ..delish.
    I’ve roasted red peppers with veggies, drizzled with balsamic glaze and parmesan before serving. More yum.
