There are only a few simple ingredients that come together to make this yummy frozen Brussel sprouts air fryer recipe.
Here's everything that you'll need:
Frozen Brussel sprouts
The base of this tasty side dish is 12 oz. of frozen Brussels sprouts.
Frozen vegetables are just as nutritious as fresh vegetables – sometimes even more so because they're frozen as soon as they're harvested rather than sitting in delivery trucks and grocery stores over a couple of weeks.
These frozen sprouts are absolutely scrumptious. Plus, they're low in carbohydrates, making them a great keto-veggie option.
In order to get these air fryer Brussels sprouts perfectly browned and crispy, a bit of olive oil goes a long way.
In addition, olive oil adds great taste, is a source of healthy fats, and prevents your sprouts from sticking to the air fryer basket.
If you don't have it on hand, another neutral oil, like avocado oil, is fine as a substitution.
Simple seasonings, including garlic powder, salt, and pepper, add subtle flavor to this side dish; it doesn't require much to make these sprouts shine!
Some shredded parmesan cheese makes a delicious addition to these air fryer frozen Brussel sprouts; it adds extra flavor and fat content.
Parmesan cheese has a salty, slightly nutty flavor that enhances these Brussels sprouts tenfold!
I also add some chopped bacon to the finished sprouts. Bacon is excellent for a keto diet because it's fatty, low-carb meat; it's the perfect finishing touch to this air fryer Brussel sprouts recipe.
My favorite way to cook bacon is in the oven!

How to make frozen Brussel sprouts in the air fryer
Follow these easy steps for a delicious frozen Brussel sprouts air fryer recipe!
Prep your elements
Begin by preheating your air fryer to 400°F.
You can also take this time to gather your required ingredients and removable pan for ease of cooking.
Dress your sprouts
Next, place your frozen Brussel sprouts in a pan that will fit within your air fryer; this will make cleanup so much easier later on!
Drizzle your Brussels sprouts with olive oil, then pop them in your preheated air fryer for 10 minutes.
Note: No need to let your sprouts thaw; they'll actually crisp up better if you cook frozen Brussel sprouts.
Season and air fry
Remove your tray and sprinkle your Brussels sprouts with garlic powder, salt, and pepper, tossing to combine.
Then, air fry your dish for an additional 10 minutes; you'll know your sprouts are done when they are tender on the inside and crispy on the outside.
Add toppings and enjoy
Finally, when serving, sprinkle your air-fried Brussel sprouts with bacon and with parmesan cheese.
How to serve
These Brussel sprouts make a great side dish because they're tasty on their own but subtle enough to pair with several dishes. Add them to the side of your favorite keto proteins like these roasted chicken legs, boneless pork ribs, or keto chimichurri flank steak.
Leftover Brussels sprouts are versatile and add some extra nutrition to your plate. Fry leftover sprouts in the air fryer for five minutes or until crispy and warmed through. Then, add them as a side to a southwestern chicken salad, a keto grilled cheese sandwich, or turkey zucchini meatballs.
While this frozen Brussel sprouts air fryer recipe is tasty as is, here are a few variations you can use to switch things up:

- Add additional seasonings like cayenne pepper, onion powder, chili flakes, and more.
- Air fry fresh Brussels sprouts, reducing the cooking time to 10 minutes total.
- Include crumbled feta or blue cheese instead of parmesan.
