While I love fresh brussels sprouts recipes (like these brussels sprout chips), it definitely takes some time to prep fresh brussels. 

Frozen brussels sprouts can just be put right in the oven without any extra work from me!

how to make roasted frozen brussel sprouts

To make these roasted brussel sprouts, first preheat the oven to 400 degrees.

Place the frozen brussels in a bowl and drizzle with olive oil, garlic powder, onion powder, and salt and pepper.

Stir until the olive oil and spices coat the brussels sprouts.

Place the sprouts on a nonstick baking sheet and spread out into an even layer. 

Roast at 400 degrees for 10 minutes.

At this point, the sprouts should be soft enough to cut through.

Cut each brussel sprout in half, and return to the baking sheet.

Once you are done cutting them all in half, sprinkle the sprouts with freshly grated parmesan cheese and return to the oven to keep cooking.

Roast for around 35 – 45 minutes, checking every 15 minutes to stir the brussels sprouts. 

Towards the end, watch them closely as we want to get those nice browned crispy edges, but avoid burning.

Those crispy parmesan cheese edges are what give these brussel sprouts so much flavor! 

They are a nice texture without being mushy, and those caramelized edges are everything.

When cooked correctly, yes!

It’s important to get the right texture, which we do by roasting them at a high heat and coating in parmesan cheese.

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 :)
