GET IT NOWThese Roasted Frozen Brussels Sprouts Are My Last-Minute Time Saver
We’ve all been there: It’s a weeknight and you’re staring into your fridge, realizing that you have no side dish for dinner. If you’ve got frozen brussels sprouts, roasting them from frozen is a quick and tasty solution, requiring almost zero prep. Here’s why I love these roasted frozen brussels sprouts:
- Savory roasted flavor – Roasting brings out a rich, savory taste in sprouts. These deliver all the flavor and crunch of traditional roasted brussels sprouts, except this time I used frozen ones and didn’t even thaw them!
- Charred and crispy outside, tender inside – The key is in the method. If you want roasted frozen brussels sprouts that actually taste good, don’t just roast them whole the entire time. (And definitely don’t steam them like the bag might say!) I get them crispy on the outside with a super easy 5-step process.
- Simple ingredients – With just 4 ingredients, this recipe is easy and straightforward. I tested it using the kind from the freezer aisle at the grocery store, but it would work with fresh ones you freeze yourself, too.
- Hands-off cooking – Unlike stovetop brussels sprouts, you don’t need to keep an eye on these.
- Fast for a frozen veggie – It takes only 30 minutes from freezer to table!
Although I use fresh brussels sprouts when making smashed brussels sprouts, crispy air fryer brussels sprouts, and fried brussels sprouts with bacon, roasted frozen brussels sprouts are ideal for busy nights when you didn’t plan. Make them with me!
“Made these last night and they are delicious. Even my husband liked them. There weren’t any leftover. Will be making them again.”

How To Roast Frozen Brussels Sprouts
I have step-by-step photos here to help you visualize the recipe. For full instructions with amounts and temperatures, see the recipe card.
- Season. Place the frozen brussels sprouts in a large bowl and toss with the avocado oil, sea salt, and black pepper.
- Arrange and bake. Spread out the sprouts on a large sheet pan (this is my favorite and never sticks!) in a single layer. Roast frozen brussels sprouts in the oven, until sprouts thaw and are no longer rock hard.
- Slice and season more. Cut the brussels sprouts in half. Toss with additional oil and sea salt, then spread out on the sheet pan again.
- Bake again. Continue to roast frozen brussels sprouts, until tender.
- Broil. Place them under the broiler on the top rack, flipping to brown both sides.
Tips For Roasting Brussels Sprouts From Frozen
Baking frozen brussels sprouts is pretty straightforward, but here are my tips I discovered when testing this recipe:
- Do not thaw the sprouts. This will just make them mushy and watery. Instead, roast them from frozen.
- Avoid parchment paper if you can. You can line your pan with foil or leave it bare, but parchment paper tends to inhibit browning.
- Use an extra-large rimmed baking sheet. You want the sheet to be bigger than you think you’ll need. That’s because you should…
- Make sure all the sprout halves touch the pan. Giving them plenty of room like this ensures that they brown instead of steaming. This is important with roasting all kinds of veggies, but even more so if they were previously frozen.
- Cut them in half once you can. Frozen brussels sprouts will be too hard to cut open right away, but do so as soon as they’ve softened enough to slice. Unlike some frozen veggies that don’t need additional slicing to cook (like air fried frozen broccoli florets), brussels sprouts benefit from the extra surface area when you slice them.
- Roast at high temperature. This is important to help get rid of any excess moisture that is common with frozen vegetables. 400 degrees F is ideal.
- Broil at the end. It’s a must for that browning and the best flavor! I found that unlike fresh sprouts, frozen ones don’t brown from roasting alone without broiling.

- Tips: Check out my recipe tips to help you make these roasted frozen brussels sprouts crispy, not mushy.
- Store: Keep leftovers in an airtight container in the fridge for up to 3-4 days. They’ll be softer later, but still flavorful. I don’t recommend freezing a second time.
- Reheat: Warm in the oven at 350 degrees F for about 10 minutes, or until hot.
- Leftover ideas: Try them for a cooked version of my brussels sprouts salad, or shred them to make shredded brussels sprout hash.

Recipe Variations
I wrote this as a simple tutorial to teach you my method, but you can easily customize it with different seasonings and add-ins. Here are my favorite upgrades:
- Herbs & spices – 1/2 teaspoon of garlic powder is the spice I add most often! You can also add 2-3 teaspoons of Italian seasoning, or a blend of cumin and coriander for an earthy, warm flavor. You can add these in the beginning, but it works better after the initial baking step.
- Bacon – Toss chopped bacon with the frozen sprouts and let it cook together with them. (This is similar to making fresh brussels sprouts with bacon.) Or if you have leftover oven-baked bacon or air-fried bacon, you can just crumble it over the sprouts at the end.
- Sweet glaze – Coat with honey or maple syrup before the second baking step. They get nice and caramelized! (This works with sugar-free honey or maple syrup, too.)
- Balsamic – Drizzle a bit of balsamic glaze on your sprouts for a tangy flavor boost. It’s a simple way to make them extra special. You can also add 1-2 tablespoons of balsamic vinegar before the second baking step. Or try my roasted balsamic sprouts.
- Crunchy topping – Add chopped almonds or walnuts in the last few minutes of roasting for a crunchy, nutty texture. You could also mix in dried cranberries and pecans, ideal for holiday meals.
- Cheese – Sprinkle them with either shredded or finely grated Parmesan cheese, either in the last few minutes or fresh out of the oven.
Serving Ideas
If you’re like me and haven’t prepped a side, you probably haven’t prepped a main course either. ? So, here are some last-minute easy dinner recipes to serve up with your sprouts:
- Chicken – Head to the freezer and whip up some frozen chicken wings in the air fryer or make some crispy chicken thighs in the Instant Pot.
- Fish – Fish recipes are always quick to thaw and fast to cook! On busy weeknights, I tend to make pan fried cod, buttery pan seared salmon, or zesty pan seared tilapia in lemon butter sauce. If all you have is frozen fish, try my air fryer frozen salmon that you can make without thawing.
- Pork – Air fried pork chops are ready in just 12 minutes, but pork steak is a close second.
- Steak – For the fastest options, make the juiciest sirloin steak in the air fryer or some sirloin steak tips. For a fancier meal, filet mignon is my absolute favorite cut.

0I am so glad you admitted that you tried a few ways to make them taste better until you got the spices. It takes a few times to perfect Brussel sprouts. Of course, they are better with BACON!

0Wow- I love Brussel sprouts and wouldn’t have known that they would turn out so well right from frozen. Thanks for the tips. I’ll find more reasons to make Brussel sprouts throughout the year for sure.
