Preheat oven to 400 degrees F (200 degrees C). Line a baking sheet with aluminum foil.

Combine Brussels sprouts, olive oil, salt, and pepper in a bowl; mix until evenly coated. Spread sprouts onto the prepared baking sheet.

Bake in the preheated oven until edges are starting to wilt, about 20 minutes. Transfer sprouts to a bowl.

Heat butter and hot sauce in a saucepan over low heat until melted and smooth, 2 to 3 minutes. Pour mixture over sprouts and stir until coated.
