Roasted Broccoli and Cauliflower Recipe

Getting my kids to not only eat veggies but ask for seconds is much easier to do with this amazing oven-roasted broccoli and cauliflower. Everyone just loves it! If you love my parmesan roasted broccoli or my roasted cauliflower, this is especially for you!

It’s a quick and easy way to put together a healthy, gluten-free, and vegan side dish with minimal effort. It doesn’t need any hovering which means you can concentrate on putting together an epic main dish.

I love that you can play around with the seasonings and decide if you want more of the Parmesan cheese crunch or a little bit of extra garlic. Maybe both! Either way, these crispy tender veggies boast so much flavor!

Key Ingredients

  • Cauliflower florets – Pick cauliflower that is white, firm, no brown or black spots, and whose leaves are firm and not wilted. It should feel heavier than it looks when picked up! 
  • Broccoli florets – Same goes for the broccoli, it should be nice and green, no black spots, and it should look fresh overall. 
  • Olive oil – Needed to coat the veggies to allow the seasoning to stick but also to help avoid the veggies sticking to the baking sheet.
  • Seasoning – Salt, black pepper, and garlic powder are all you need. Roasting veggies at high heat gives them a beautiful char and brings out all of their natural flavors.
  • Parmesan cheese – Optional, but I love adding a sprinkle to mine for extra cheesy crispiness. 

TIP: Cut the head of cauliflower and the head of broccoli in half lengthwise so there is a flat side to the florets. It’s easier to lay them flat on the baking sheet this way.

How to Roast Broccoli and Cauliflower

  1. Oil: Lay cut veggies down on a sheet pan lined with parchment paper. Pour olive oil over all of them.
  2. Seasoning: Sprinkle an even amount of seasoning over top and give them a good toss. 
  3. Roast: Cook the vegetables in the preheated oven for 20 minutes before flipping. Add some parmesan cheese if desired and continue to bake for another 5-10 minutes. They should be nice and crispy on the outside edges and fork-tender on the inside.
  4. Serve: Remove them from the oven and sprinkle with salt and pepper to taste. Enjoy this easy side dish while it’s hot!

Recipe Tips

  • Don’t overcrowd the pan. For everything to crisp up nicely, you’ll need to leave room for the air to circulate. Otherwise, you’ll end up with mushy veggies.
  • The above-mentioned note is why it’s important to give the florets a straight edge. There’s less chance they’ll roll around and move.
  • Make sure to dry your florets before seasoning. Again, you don’t want soggy veggies!

Seasoning Variations

If you’re working with the seasonings already listed, feel free to play around with the amount. 


Can I roast broccoli, cauliflower and carrots together?

Absolutely. If you’re looking to add more veggies to your tray you want to make sure you’re roasting veggies that have the same cook time. That way you’re not burning and under baking at the same time. 

Brussels sprouts, potatoes, and sweet potatoes also work, but you may need to start roasting them first and then add your cauliflower and broccoli in after. You can add faster cooking veggies if you want, but you’ll have to time it so they all finish cooking at the same time.

Can you freeze roasted broccoli and cauliflower?

You can! Make sure they’re completely cooled then transfer them to an airtight container or freezer-friendly bag. Keep them frozen for up to 3 months. 

What temperature to roast cauliflower and broccoli?

Roasting anything usually requires high heat. I like to preheat my oven to 400 degrees. I find that always leads to perfectly crispy yet tender roasted vegetables.

What to Serve with Roasted Cauliflower and Broccoli

This is the perfect side dish for simple and casual or a little more elegant. It’s also just as acceptable to eat an entire bowl on its own.  

How to Store and Reheat

Store any leftovers of your roasted broccoli and cauliflower in an airtight container in the refrigerator for up to 3 days.

To reheat, spread in an even layer on a large baking sheet and heat at 350°F for up to 10 minutes or until heated through. You could also reheat in a skillet on medium heat with a drizzle of olive oil or in the microwave until warmed throug.
