Do you cringe when you hear the word brussels sprouts? Please don't! They are so yummy. What do brussels sprouts taste like? They are soft and crunchy and have a slightly bitter taste.
I like to think of them as baby cabbages. If you like cabbage, you may love brussels sprouts! You can read about How Brussels Sprouts Can Benefit Your Health here.

How to Make Air Fryer Brussels Sprouts

Air Fryer Temperature
I use 350 degrees for brussels sprouts.

8-10 minutes is a good time for crispy brussels sprouts. You will want to monitor them to ensure they do not overcook. Mine were perfect right at 10 minutes.
How to Make Them From Frozen
In general, fresh brussels sprouts will work so much better. If you use frozen brussels you will have to cook them first (using the same temperature).
After the brussels are no longer frozen, then add the balsamic vinegar and seasonings and place the brussels back into the air fryer. The brussels may need up to 12-minutes to cook, but use your judgment.

Ingredients
- 1 ½ -2 cups fresh brussels sprouts each sliced in half
- ½ cup sliced red onions
- 1 tablespoon balsamic vinegar
- 1 tablespoon olive oil or cooking oil spray
- salt and pepper to taste
Instructions
- Add the brussels sprouts and sliced red onions to a bowl. Drizzle olive oil (or spray cooking oil) and balsamic vinegar throughout.
- Sprinkle salt and pepper to taste. Stir to evenly coat.
- Spray the air fryer basket with cooking oil.
- Add the brussels sprouts and onions. I was able to add the entire amount to the basket without needing to cook in batches. I have the 5 quart Power Air Fryer. Do not overcrowd the basket. Cook in batches if necessary for your air fryer model.
- Cook for 5 minutes on 350 degrees.
- Open the air fryer and shake or toss the veggies with tongs.
- Cook for an additional 3-5 minutes. At 8 minutes mine were slightly charred but still soft. Right at 10 minutes, mine were crisp. Every air fryer brand cooks differently. Use your judgment to assess the optimal cook time.
- Cool before serving.

Can You Air Fry Frozen Brussels Sprouts?

Looks delicious! We love Brussels sprouts and now I'm excited to make them in my air fryer!
Joe says
We enjoyed these yesterday. I like my sprouts a little crispier, so we kept them in there for 12 minutes. Red onion is the perfect addition and the simplicity of this one is a nice touch.
staysnatched says
Simple and delish!
Nicole says
Finally got to use my air fryer and was very pleased with having this be my first recipe. Easy and tasty! Will definitely make again.
staysnatched says
Yay! So glad you enjoyed the recipe.
Taryn says
Just made these for lunch. I omitted the red onion as I didn't have any, but the sprouts came out delicious. I almost took them out around 7 or so minutes but I tried one and they weren't done in the middle. 10 minutes was perfect.
staysnatched says
Awesome! Glad you enjoyed the recipe.
Teresa says
Made these last night...they were DELISH! Not sure why it never crossed my mind to air fry with onion...I don't think I'll ever NOT use onion again! Ha!
staysnatched says
haha! It's a great little trick.
Carli says
Made these tonight and they were delicious. They were crisp but still were soft. I used avocado oil. I personally need to work on the timing but 100% going to use this recipe again
staysnatched says
Glad to hear you will make them again.

Love it when simple and delicious work so well together. The balsamic vinegar combined with the crispy Brussels sprouts and red onion is very tasty. We had these tonight with the Keto Low Carb Chicken Wings (Maple BBQ). A perfect weeknight dinner!
staysnatched says
I'm so glad you enjoyed the recipe.
Jacqueline says
Quick and easy recipe. My new favorite recipe in rotation. I have the ninja air fryer and I cooked mine to 12 minutes since I like them crisper and they were perfect. Don’t skip the onion!
staysnatched says
The onion provides so much flavor!

Had a handful of brussel sprouts looking lonely in my fridge and came right to Brandi because I knew she’d have something easy, quick, and delicious! Hit the spot and helped me choose a healthier side for my dinner.
staysnatched says
I’m glad you enjoyed them!
Shunta says
I had some amazing brussels sprouts at a local restaurant and wanted to recreate them. I knew I could trust coming to Brandi for a recipe and per usual she didn't disappoint! I drizzled with Trader Joe's Hot Honey trying to recreate the sweetness from the restaurant.
staysnatched says
That sounds so good!
