I’ve always loved experimenting with ways to make Brussels sprouts way more exciting, and this air fryer recipe totally blew my mind. I started with a pound of trimmed and halved Brussels sprouts tossed in 2 tablespoons of olive oil, a bit of salt, black pepper, and garlic powder to really bring out the flavor.

Once those little greens got crispy in the air fryer, I sprinkled on a generous amount of grated Parmesan cheese and even hit it with a dash of red pepper flakes for an extra zing. The result was a dish that’s crunchy on the outside yet tender inside, perfect for those following a low carb, keto lifestyle.

I’ve played around with similar air fryer recipes before, from vegan options to hearty keto side dishes, and this one stands out for its simplicity and flavor. Give it a try if you’re looking for a healthy twist on a classic vegetable side dish.

Why I Like this Recipe

I love this Parmesan Air Fryer Brussels sprouts recipe for a bunch of reasons. First, I really like how super crispy and savory they turn out every time I make them. Second, I appreciate how simple it is – I just trim the sprouts, toss them with olive oil, salt, pepper, and garlic powder, then air fry them till they’re just right. Third, the Parmesan cheese packs a punch of flavor that makes the dish feel extra indulgent while still being healthy and keto friendly. And lastly, I dig that little kick from the red pepper flakes which keeps things exciting even if I’ve made it a hundred times before.

Crispy Air Fryer Brussels Sprouts (Low Carb, Keto) Recipe Substitutions and Variations

Instead of olive oil, you can use avocado oil or even melted coconut oil for a different tasty twist.
For salt, try Himalayan or sea salt if you want a slightly different mineral flavor.
If you dont have garlic powder, you could use 1 small clove of minced fresh garlic (but be careful, as it might burn a little if not mixed in fast enough).
Instead of Parmesan cheese, grated Pecorino Romano can work well if you’re looking for a sharper taste.
If you dont like red pepper flakes, consider using a pinch of cayenne pepper to still keep some heat in the dish.

Pro Tips

1. Make sure all the sprouts are cut up so they cook evenly. It helps if you let them sit in the oil and seasonings for a little bit before tossing them in the air fryer so they can absorb more flavor.
2. Remember to give the air fryer basket a few shakes halfway through cook time. This little move makes sure nothing sticks together and every piece gets nice and crispy.
3. If you’re feeling adventurous, try adding a squeeze of lemon or a drizzle of balsamic vinegar after they’re done. It gives them a fresh twist without messing up the original flavors.
4. When you add the Parmesan, be careful not to overdo it. Too much cheese can get burnt, so go light if you don’t want a smoky taste.
