Preheat your oven to 400 degrees. Line a baking sheet with tinfoil and spray it with a little bit of olive oil spray (or other cooking spray you have on hand) then set it aside.
Chop all of your brussels sprouts in half and put them in a mixing bowl. In a separate bowl combine your maple syrup and sriracha and whisk them together well. Pour this mixture over your brussels sprouts and toss thoroughly to coat.
Pour out your sprouts onto your lined baking sheet and spread them out evenly. Bake for 30-40 minutes or until your sprouts are tender on the inside and crispy on the outside.
