Preheat Your Air Fryer: Start by preheating your air fryer to 350°F. This ensures your Brussels sprouts will cook evenly.

While the air fryer is heating up, take your frozen Brussels sprouts and place them in a medium mixing bowl. Drizzle a bit of vegetable oil over them, add salt, black pepper, light brown sugar, and a pinch of light soy sauce. Toss everything together to coat the sprouts evenly.

Once your Brussels sprouts are seasoned, it's time to load up the air fryer basket. Make sure they are in a single layer for the best texture. If you have a lot of sprouts, you may need to cook them in batches.

Cook your frozen Brussels sprouts in the air fryer for 6 minutes, shaking the basket for even cooking. Then, continue to air fry for an additional 10 minutes at 400°F. Done! Add two more minutes of cook time if you prefer a crispy side like me. Keep a close eye on them to achieve those crispy edges without burning.

Garnish them with some roasted sesame seeds if you want. Serve and enjoy!
