Step 1

Preheat the Air Fryer 375°F (190°C) for Brussels sprouts.

Step 2

Prepare the Brussels Sprouts: Trim fresh brussels sprouts and thaw if using frozen. (If your frozen Brussels sprouts are clumped together, give them a quick shake or tap to separate them. This will help them cook more evenly.)

Step 3

Place brussels sprouts in a medium mixing bowl. Drizzle with 2 tablespoons of olive oil and balsamic vinegar. (Teriyaki also works!) Toss to coat then season with garlic salt, black pepper granulated garlic and sugar. Toss again to coat then add additional oil, to taste.

Step 4

Arrange in air fryer basket in a single layer. Avoid overcrowding to ensure proper air circulation and even cooking. If needed, cook the brussels sprouts in batches.

Step 5

Cook the brussels sprouts at 375°F (190°C) for about 15-20 minutes stopping halfway through to shake the basket and turn for even browning.

Step 6

Test with the tip of a knife for doneness. They should be crispy on the outside and tender on the inside. If you prefer them extra crispy, you can cook them for a few more minutes.

Step 7

Transfer air-fried Brussels sprouts to a serving dish. You can sprinkle a bit more salt and pepper and garnish with shredded or grated Parmesan cheese, if desired. Serve immediately.
