This easy Oven Roasted Brussel Sprouts recipe will make everyone love Brussel Sprouts!
They are the most crispy Brussel sprouts with delicious soft garlic flavors and are also 100% dairy-free, keto, and vegan.
There are many ways to roast Brussel sprouts. You can air fry, roast in a stir fry pan, or oven roast them!
I prefer oven-roasted sprouts because you can prepare a large batch, and they come out really crispy!
How To Roast Brussel Sprouts
All you need to make quick and easy Brussel sprouts are:
Ingredients
- Fresh Brussel sprouts – See paragraph below for frozen option. Brussels Sprouts are delicious, healthy, and low-carb vegetables.
- Extra Virgin olive oil
- Kosher Salt
- Black Pepper
- Garlic powder
Cutting In Halves
First, prepare the vegetable. Wash the sprouts under clean water in a sieve.
Then cut the stems off each sprout and discard them before slicing the sprouts in halves. There are two ways to cut Brussels Sprouts, find your favorite in my Brussels Sprouts cutting guide.
Some outer leaves will fall out, and you can keep them for later to make Brussels Sprouts Chips. Discard yellow leaves.
Next, prepare the oil mixture. Stir all ingredients together in a small mixing bowl: garlic powder, olive oil, salt, and pepper.
Spread the oil mixture over the halves and massage or stir very well to evenly coat each half with the oil mixture.
Add-Ons And Variations
Of course, you can tweak this recipe by adding some extra flavors to your oil mixture like:
- Red Pepper Flakes – optional, only use some for a touch of spice.
- Maple Syrup – add one or two tablespoons to make maple-roasted Brussel sprouts.
- Lemon Juice – or lemon zest
- Balsamic Vinegar – or balsamic glaze
- Soy Sauce
- Rosemary and melted butter
Roasting Time
Preheat the oven to 400°F (200°C) and line two sheet pans or one large rimmed baking sheet with parchment paper.
You don’t have to use parchment paper, but it makes it much easier to clean the tray later on.
Also, make sure the pans are large enough to spread the batch of vegetables in a single layer, leaving some space between each.
In fact, if they are too close to each other, they won’t crisp as much.
Spray oil over the paper and toss the Brussels sprouts halves on the tray, cut-side face down first.
Bake the Brussels sprouts for 15 minutes, then flip and bake them for an extra 10 minutes.
Oven-roasted Brussels sprouts are ready within 25 to 35 minutes when they start to crisp on the outside.
Depending on the size of each, cooking time vary. It can take a little bit longer.
You know they are ready when the outside is crispy, golden brown, and slightly soft in the inside but still crunchy.
You should be able to prick a knife in the center of the half easily.
Roasting Frozen Brussel Sprouts
If Brussel sprouts are not in season, frozen vegetables are always a great way to add nutrients to your day.
To roast frozen Brussel sprouts, simply follow the recipe below, but roast the frozen sprouts (don’t thaw them) for 15 minutes before adding the olive oil mixture around.
Then cover with olive oil and keep baking for 15 minutes or until crispy.
Note that frozen roasted vegetables never get as crispy as fresh vegetables. They are softer and can be slightly mushy.
Serving Plain
Serve these immediately to enjoy their best crispy texture.
Next, you can use these roasted sprouts plain or add on top some of the below:
- Drizzle of lemon juice or honey
- Freshly grated parmesan cheese and toasted bacon
- Balsamic vinegar
- Stir fry sauce – cook the sauce to thicken and drizzle on top of the roasted vegetable

- Microwave them in a microwave-safe dish for 1-2 minutes or until hot.
- In a nonstick pan over low-medium heat, cover with a lid, and occasionally stir until warm.
- In the air fry, air fry the Brussel sprouts at 300°F (150°C) for 5 minutes or until warm in the center.
