Air Fryer Smashed Brussels Sprouts Recipe

I thought that roasting Brussels sprouts was my favorite way to make them, but then I discovered air fryer Brussels sprouts. Whoa! They’re quicker this way and you can get them to be delightfully crispy without a ton of oil.

And when you want crispy Brussels sprouts? Well, smashing them is the way to go. By steaming them first, you can give the sprouts a good whack and get them flat. Smashed Brussels sprouts give you more surface area for crisping up, and also more surface area for seasoning with tangy balsamic vinegar and savory Parmesan cheese. If you’re still not convinced that Brussels sprouts are delicious, these air fryer smashed Brussels sprouts will change your mind!

Ingredients

See recipe card below this post for ingredient quantities and full instructions.

  • Brussels sprouts
  • Olive oil
  • Balsamic vinegar – Use a thick, syrupy balsamic vinegar if you can find one. They have the best flavor and won’t make your sprouts soggy!
  • Grated Parmesan
  • Salt and pepper to taste

Variations

You can add chili flakes or fresh or dried herbs (I love thyme, sage, and rosemary with Brussels sprouts!) to your smashed Brussels sprouts if you like. You can also serve them with brown butter for dipping or drizzling, or sprinkle them with bacon. (Bacon and Brussels sprouts are awesome together!)

FAQ

Why are my Brussels sprouts not crispy?

If your Brussels sprouts aren’t crispy, there could be a few potential reasons. First, it could be that your Brussels sprouts were over cooked in the microwave. Second, you might simply need to cook the Brussels sprouts longer in the air fryer. The third explanation is that you may have crowded your Brussels sprouts in the air fryer basket, which can lead to them being soggy instead of crispy.

What can I serve with these air fryer smashed Brussels sprouts?

You can use these as a side dish or an appetizer! Some of my favorite main dishes to pair with these Brussels sprouts are Easy Baked Chicken Breasts and Crock Pot Ham. If you’re making them as an appetizer, consider serving them with Cranberry Brie Bites.

Can I make smashed Brussels sprouts without an air fryer?

Yes! You can cook them at 400ºF in the oven for about 20 minutes, flipping them at the halfway point.
