Add the brussel sprouts to a large bowl and pour the olive oil mixture over top and toss to coat.
Spread the brussel sprouts out on the baking sheet, cut side down, leaving some room in between each, and bake in the oven for 16 - 18 minutes, flipping the pan around half way through to ensure even browning. Shake the pan to loosen up the brussel sprouts and broil for 1 - 2 minutes until extra crispy.
Transfer the brussel sprouts to a serving dish immediately while still hot and enjoy!
Notes
Storing : Store the roasted brussel sprouts in an airtight container in the fridge for up to 5 days. When ready to enjoy, crispen them up again in the toaster oven or oven at 400 F for 5 minutes or in the air fryer for 3 minutes at 400.
