What is the best way to cook brussel sprouts in the air fryer?

The best way to cook brussel sprouts in the air fryer is to use frozen brussel sprouts! This is because frozen brussel sprouts cook more evenly than fresh, and they don’t require as much attention as cooking fresh brussel sprouts in the air fryer. An added bonus: you don’t have to chop or slice these frozen brussel sprouts.

Fresh brussel sprouts are tough to cook in the air fryer because of all the little leaves at the base of the brussel sprout that pull away from the brussel sprout when cooking. These leaves start to burn and the air fryer basket needs to be shaken often, which can be time consuming.

How to prep brussel sprouts

The beauty of making brussel sprouts is that there is no cutting or prep required! Simply empty the bag of frozen brussel sprouts into the air fryer and turn it on.

See step by step instructions for both air fryer brussel sprouts or oven bake brussel sprouts below.

How to cook frozen brussel sprouts in the air fryer:

Step 1: Open the bag of frozen brussel sprouts directly into the air fryer basket. Turn the air fryer to 390F and set it for 14 minutes.

Step 2: After 9 minutes, take the basket out of the air fryer and spray the brussel sprouts with olive oil or avocado oil and sprinkle with salt. Shake the basket well to distribute the salt. Place the basket back into the running air fryer.

Step 3: After the air fryer turns off, shake the brussel sprouts again and sprinkle with a pinch more salt. Serve hot.

How to cook frozen brussel sprouts in the oven:

Cooking frozen brussel sprouts in the oven is so simple! No need to cut the brussel sprouts in half, just roast them whole.

Step 1: Start by preheating the oven to 450F. Place parchment paper or a silicone liner on a baking sheet. Add the frozen brussel sprouts (at least 2 bags) onto the baking sheet. Put baking sheet in the preheated oven.

Step 2: After 20 minutes of roasting at 450F, take the brussel sprouts out of the oven. Spray them with olive oil or avocado oil and sprinkle with salt. Stir around the pan well to distribute the salt evenly. Place back in the oven for 10 minutes.

Step 3: After 10 minutes of additional cooking, remove the brussel sprouts from the oven and sprinkle again with salt. Serve hot!

Tips for cooking frozen brussel sprouts:

The perfect cooking time for frozen brussel sprouts depends on the size of the brussel sprouts.

For frozen brussel sprouts the size of a dime or nickel, follow the directions above.
For frozen brussel sprouts the size of a quarter or larger, add 1 minute to the air fryer cooking time and 5 minutes to the oven roasting method.

If you want to add even more flavor to the brussel sprouts while cooking, instead of spraying them with olive oil or avocado oil, use a roasted garlic olive oil or roasted garlic avocado oil. You can add flavored olive oil into a spray bottle for easy coverage.

If you really want the inside of the brussel sprouts to get crispy, I would recommend using fresh brussel sprouts and following these instructions to make the best crispy brussel sprouts!

Make a double or triple batch for meal prep! Simply store cooked roasted brussel sprouts in the fridge for up to 4 days. You will want to get an extra large baking sheet if you plan on making more than 3 bags of frozen brussel sprouts at one time!

So excited to try this. The recipe might be clearer if it said “after 9 minutes ....” then I would have understood the total cook time was 14. Took me a bit reading the comments to understand the recipe and timing. Almost fingerfood and I can see dipping sauce possibilities here!!! Whoot!!!

I appreciate you taking the time to make that suggestion Jill! I have updated the instructions per your request! Thank you for making me see that my original instructions were not clear (sometimes you can get tunnel vision when writing these).

I have an instant pot air fryer too, used the small frozen Brussels sprouts bag and the inside was still too mushy :/ The outsides were fine and crispy

I wonder if I should cut them in half - half way through cooking next time

Wednesday 28th of October 2020

That would certainly help if you are finding they are not cooked well enough all the way through! Let me know if you try that!

Amazing! I actually love them. My first attempt, with fresh ones in the oven, was not quite successful. I made a creamy cashew and mustard sauce to go with them!

Great recipe! Thank you. I did Frozen Brussles at 390 for 14 minutes with the instant pot air fryer lid! Worked great. I used the olive oil spray to spray the basket, and then used avocado oil and just coated them with that and some pink salt! Came out very tasty. I used Yumm Sauce as a dipping sauce!
