Why The Air Fryer is Superior for Roasting

While you can certainly roast vegetables in a traditional oven, the air fryer is vastly superior for Brussels sprouts. The rapid, circulating super-convection heat of the air fryer draws out the moisture from the outer leaves in minutes, creating a deep, caramelized char that is almost impossible to replicate in a standard oven. Plus, it only takes 10 minutes of cooking time compared to the 25-30 minutes an oven requires!

The Secret to Maximum Crispiness

If you want the crispiest possible sprouts, there are two golden rules you must follow. First, do not overcrowd the basket. The sprouts need space for the hot air to circulate around them. If they are piled on top of each other, they will steam instead of roast, resulting in soggy vegetables. Second, do not throw away the loose leaves! When you trim and halve the sprouts, some leaves will naturally fall off. Toss those loose leaves in the oil and cheese and put them right into the air fryer. They will turn into incredible, potato-chip-like crisps that are the best part of the dish!

Frequently Asked Questions

Can I use frozen Brussels sprouts?

It is highly recommended to use fresh Brussels sprouts for this recipe. Frozen sprouts hold a massive amount of water and will turn out mushy rather than crispy. If you absolutely must use frozen, you will need to increase the cooking time by 5-8 minutes and expect a softer texture.

What is balsamic glaze?

Balsamic glaze (or balsamic reduction) is balsamic vinegar that has been cooked down until it becomes thick, syrupy, and sweet. A light drizzle over the salty, savory parmesan sprouts just before serving elevates this dish to restaurant-quality perfection!

Ingredients Method

Ingredients

  

Main

• 1 lb Brussels sprouts, washed, trimmed, and halved
• 2 tbsp Olive oil
• 1/2 tsp Garlic powder
• 1/2 tsp Sea salt
• 1/4 tsp Black pepper
• 1/4 cup Parmesan cheese, grated (plus more for serving)
• 1 tbsp Balsamic glaze (optional, for drizzling)

Method

 

Main

1. Trim the tough bottom stems off the Brussels sprouts, then cut them in half from top to bottom. Discard any loose, yellowing outer leaves.
2. In a large mixing bowl, toss the halved Brussels sprouts with the olive oil, garlic powder, sea salt, and black pepper until they are evenly coated.
3. Sprinkle the grated parmesan cheese over the sprouts and toss again. Ensure the cheese gets into all the little crevices of the leaves.
4. Preheat your air fryer to 380°F (190°C) for 3 minutes.
5. Place the seasoned Brussels sprouts into the air fryer basket in a single layer. (Cook in two batches if your air fryer is small; do not overcrowd the basket!).
6. Air fry at 380°F for 10-12 minutes. Pause halfway through (at the 5-minute mark) to vigorously shake the basket, ensuring even cooking.
7. The sprouts are done when they are fork-tender on the inside and have dark, crispy, deeply caramelized edges on the outside.
8. Transfer to a serving bowl, sprinkle with a little extra parmesan cheese, and drizzle with balsamic glaze if desired. Serve immediately!
