Roasted Broccoli and Cauliflower Recipe

You can use this delicious recipe for any roasted vegetables, not just garlic and parmesan roasted cauliflower and broccoli. It is a versatile recipe that can be applied to any veggies that can be roasted.


Broccoli and Cauliflower: Cut them into florets of the same size so they all cook at the same rate. You can even roast frozen broccoli and cauliflower for this recipe. Fresh is generally better, but at certain times of the year, it can be too expensive or not good enough. Either way, you can get great results.

Olive Oil: You can use extra virgin olive oil or avocado oil.

Garlic: To get the best flavor, use fresh garlic cloves, but if you prefer convenience, you can use jarred garlic. If you don’t have them, you can use garlic powder as a substitute for the required cloves in this recipe.

Parmesan Cheese: For optimal results, it is recommended to use grated parmesan cheese instead of shredded. Grated cheese crisps better and ensures every bite of roasted broccoli and cauliflower has a cheesy crunch.

For this recipe, you need the following ingredients:

  • 4 cups Broccoli florets
  • 4 cups Cauliflower florets
  • 1/3 cup Olive oil
  • 6 Garlic cloves
  • 2/3 cup Grated parmesan cheese 
  • Salt and pepper, to taste

To begin, preheat your oven to 400F (204C). Next, line a large baking sheet with foil, or use a high-quality non-stick baking sheet without the need for lining it. If you have two smaller baking sheets that can fit side by side, you can also use those.

In a large bowl, combine the broccoli and cauliflower florets. Pour in the olive oil, garlic, and half of the parmesan cheese. Toss broccoli and cauliflower to coat them thoroughly. Then, add kosher salt or sea salt and black pepper and give it a final toss.

Place the vegetables in a single layer on the prepared baking sheet(s), ensuring they have ample space around them. Bake for 25-30 minutes or until the edges turn brown. For more uniform cooking, it’s recommended you toss them halfway through.

Just before serving, mix in the remaining parmesan cheese, and add more salt and pepper to taste, if desired.

Roasted Broccoli and Cauliflower Recipe Tips and Variations

To roast veggies perfectly, use sufficient oil, thinly layer the pieces on the pan, and set a high temperature. Ensure the florets are coated with a thin layer of oil. Although 1/3 cup of olive oil may seem excessive in this recipe, it is divided among 8 cups of veggies.

For optimal roasting of your broccoli and cauliflower, it’s important to give them sufficient space in the pan. Arrange the florets in a single layer without overlapping, and try leaving some gaps between them. Overcrowding the pan will result in steamed vegetables instead of the crispy roasted texture you desire.

To ensure that your vegetables roast properly and don’t steam, it’s important to use a high oven temperature. A higher temperature will absorb moisture more quickly, preventing steaming. For firmer vegetables like root veggies, an oven temperature as high as 450 degrees may be appropriate. For this roasted broccoli and cauliflower recipe with parmesan cheese, a temperature of 400 degrees is sufficient to avoid burning the outside too quickly or scorching the cheese.

You can make this simple side dish more interesting by using different seasonings.

For an Italian twist, just sprinkle 1-2 teaspoons of Italian seasoning over the broccoli and cauliflower before roasting.

To add a spicy Cajun flavor to roasted vegetables, use 1-2 teaspoons of Cajun seasoning and skip the parmesan cheese.

To add Ranch flavor to your roasted veggies, you can sprinkle 1-2 teaspoons of ranch seasoning and parmesan cheese on them before or after cooking.

To add a tangy flavor, replace the salt and pepper with lemon pepper seasoning. Alternatively, you can also include lemon juice, lemon zest, or both.

How to Store and Reheat Roasted Broccoli and Cauliflower

Store leftover oven-roasted broccoli and cauliflower in the refrigerator for up to 4 days. To freeze, place leftovers in an airtight container and freeze for up to 3 months. If freezing the veggies raw, blanch them in boiling water for a few minutes first to prevent a mushy texture after thawing.

To reheat, use an oven set to 350 degrees for the best results. Microwaving is an option but may result in softer vegetables. Alternatively, reheating in an air fryer will help maintain the original texture.

Frequently Asked Questions

Should I Steam Vegetables Before Roasting Them?

You can roast vegetables without steaming them as roasting alone is enough to cook them perfectly. However, steaming can partially cook denser vegetables like broccoli and cauliflower, reducing the roasting time and ensuring even cooking.

Is Roasting Vegetables Healthier Than Boiling Them?

Roasting vegetables is a healthier way to cook them compared to boiling because it retains more nutrients. Boiling can result in the loss of nutrients in the cooking water which is often thrown away. Moreover, roasting gives vegetables a satisfying texture and flavor, making them more enjoyable to eat.

Does Cauliflower Take Longer to Cook Than Broccoli?

Cauliflower takes more time to cook than broccoli due to its denser and thicker texture. Roasting cauliflower typically takes 20-25 minutes, while broccoli takes only about 15-20 minutes. It’s worth noting that the cooking time may differ depending on the size and thickness of the cuts.
