Preheat the air fryer for 5 minutes at 385 degrees F.
Meanwhile, in a large mixing bowl, whisk together the olive oil, maple syrup, vinegar, salt, pepper, and red pepper flakes until fully combined; reserve.
Add the brussel sprouts and bacon pieces to maple syrup mixture in the mixing bowl; toss well to coat evenly.
Transfer the brussel sprouts to the rack in the air fryer basket, spreading them out as evenly as possible in a single layer.
Roast the brussels sprouts at 385 degrees F for 8-10 minutes, making sure to give them a gentle toss halfway through the cooking time. **Brussels sprouts should be tender when pierced with a fork at the center and the exterior is golden brown and a bit crispy.
Serve at once!
Oven
Preheat the oven to 425 degrees F. Follow the air fryer preparation steps above, spreading the brussel sprouts out over a rimmed baking sheet. Roast, uncovered, for 25-30 minutes or until fork-tender and as crispy as you'd like them, tossing half way through the cooking time.
