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.

Oven Roasted Brussel Sprouts

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:


  • Fresh Brussel sprouts – See paragraph below for frozen option. Brussels Sprouts are delicious, healthy, and low-carb vegetables.
  • Ultra Virgin olive oil
  • Salt
  • Pepper
  • Garlic powder

Cutting In Halves

First, prepare the vegetable. Wash the sprouts under clean water in a sieve.

Then cut the feet 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 Brussel Sprouts Chips.

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.


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
  • Balsamic Vinegar
  • Soy Sauce

How Long Does It Take To Roast Brussel Sprouts?

Preheat the oven to 400°F (200°C) and line two sheet pans or one large 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 line the Brussel sprouts halves on the tray, face down first.

Bake for 15 minutes, then flip and bake for an extra 10 minutes.

Oven-roasted Brussel sprouts are ready within 25 to 35 minutes.

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 middle but still crunchy.

You should be able to prick a knife in the center of the half easily.

Making Roasted Brussel Sprouts

How To Roast Frozen Brussel Sprouts

Of course, 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
  • Freshly grated parmesan cheese
  • Balsamic vinegar
  • Stir fry sauce – cook the sauce to thicken and drizzle on top of the roasted vegetable

Best Meal To Serve With Brussel Sprouts

This side dish is even more delicious and served with a meat-based dish. Below are some great ideas to serve with this recipe.

  • 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.
