You’ll Love Roasting Frozen Brussel Sprouts
Oven roasted frozen brussels sprouts are an easy and tasty dinner side dish.
If you love brussels sprouts, you will love this recipe! Roasting sprouts is the key to getting the right texture which is everything with brussels sprouts.
We love the convenience of frozen vegetables to cut down on prep time. Although brussels sprouts bake best cut in half, we let the oven do the thawing for us. Once they have baked a little bit, we can easily cut them in half and finish cooking.
While I love fresh brussels sprouts recipes (like these roasted brussels sprouts with parmesan and brussels sprout chips), it definitely takes some time to prep fresh brussels. This recipe is a big time saver!
Can you Roast Frozen Brussel Sprouts?
Yes, you can roast brussel sprouts from frozen. It’s important to get the right texture, which we do by roasting them at a high heat and coating in parmesan cheese.
Ingredients you’ll need to Roast Frozen Brussel Sprouts
- Frozen brussels sprouts
- Olive oil
- Salt and pepper
- Garlic powder
- Onion powder
- Grated parmesan cheese
How to Roast Frozen Brussel Sprouts
Step 1: Preheat your oven to 400 degrees. Place the frozen brussels sprouts in a bowl and drizzle with olive oil, garlic powder, onion powder, salt and pepper. Stir to combine.
Step 2: Place the sprouts on a nonstick baking sheet and spread out into an even layer. Roast at 400 degrees for 10 minutes.
Step 3: At this point, the sprouts should be soft enough to cut through. Cut each brussel sprout in half, and return to the baking sheet. The easiest way to do this is by using kitchen scissors.
Step 4: Place the brussels sprouts back in the oven and cook an additional 10 minutes. Stir the brussels, then add the grated parmesan cheese on top.
Step 5: Continue to roast for 10-15 minutes, until the cheese is melted and browning with crispy edges
Storing and Reheating Leftover Frozen Roasted Brussel Sprouts
- How to store: Place any leftover roasted brussels sprouts in an airtight container in the refrigerator for up to 3-4 days.
- How to reheat: Place leftover brussels sprouts on a baking sheet and bake at 375 degrees until hot.
Can you freeze brussel sprouts after roasting?
I would not recommend freezing these brussels sprouts since they were previously frozen. This would result in a very mushy texture once thawed again.

How to Roast Frozen Brussel Sprouts FAQs
– Low heat: make sure to use a high oven temperature when cooking brussel sprouts to help get the crispy texture that you desire.
– Not cut in half: Cutting brussels sprouts in half (even the frozen variety) is very important to achieving a crispy texture instead of a mushy middle.
If your brussels sprouts are tough, you likely used too little oil. The brussels sprouts need to be well coated in olive oil in order to cook properly.

We love Brussels sprouts and I would love to try this recipe since we're staying home and relying on what's in our freezer, but this seems like a really long time in the oven for a food that's technically already cooked. I'm worried they'll be super soft by the time they've been in there almost an hour. Are you starting with frozen raw sprouts? Or the typical cooked and frozen ones? Thanks!

They are raw, and also frozen, which take longer to cook. They are definitely not mushy. I cook them this long so that they get crispy cheese edges! Hope that helps :)
