Preheat oven to 425 degrees F. Cut the brussels sprouts into halves or quarters depending on their size. Cover a baking sheet with parchment, making sure you can spread out the brussels sprouts so they're not on top of each other. Lightly spray the sprouts with oil and toss with minced garlic, kosher salt and pepper (I used about 1/2 teaspoon salt).
Roast for 15 minutes or until starting to brown and get "crunchy". Meanwhile make the sauce by whisking the sweet chili sauce, sriracha and mayonnaise till smooth. Set aside. Remove the brussels sprouts from the oven and spoon about half of the bang bang sauce over them, tossing everything together. Roast another 5 minutes.
Remove from oven and either coat them with the rest of the sauce to taste or use it for dipping!
Air fryer instructions - Preheat air fryer to 400F. Prepare brussels sprouts the same way in step 1, then add to the basket. Cook for 7 minutes, then shake the basket around. Cook another 6-8 minutes until brown and crispy.
