To a glass jar or bowl, add all the ingredients for the sauce- olive oil, sesame oil, maple syrup, sriracha (or any hot sauce), salt and pepper.Using a wire whisk, mix until it's all well combined. Set this aside.
Now, wash and pat dry the Brussel sprouts using a clean kitchen towel. Then trim off the end and remove any brown outer leaves. Cut each Brussel sprouts in half. If they are very big, you can also cut them in quarters. Transfer them to a large bowl.
Add the prepared sauce, reserving around 3/4 tablespoon of it which we will add at the end. Mix until the Brussel sprouts are coated with the sauce. Pre-heat your air fryer according to manufactures instructions. My gourmia air fryer has default pre-heat mode which pre-heats for 3 minutes.
Transfer the Brussel sprouts into the air fryer in a single layer. Air fry at 360 F degrees for 10 minutes, pull out the air fryer basket and shake every 5 minutes. At the 10 minute mark, add the sliced garlic. Continue to air fry 5 more minutes.
So the total time for air frying was 15 minutes. If you want extra crispy Brussel sprouts you may increase the temperature to 400 F and air fry 2 more minutes. This is optional and I didn't do it. Transfer Brussel sprouts to serving plate and drizzle with the reserved sauce. Serve immediately!
Notes
You can add chopped green onions to these before serving. Pomegranate will also be a really nice addition.
To spice it up add more of sriracha or you can also add some sliced jalapenos.
To make them extra crispy, you can air fry at 400 F for 2 minutes at the end (optional).
