Roasted Brussels Sprouts with Bacon and Parmesan Cheese is an easy side dish that’s full of flavor. The sprouts roast until tender, then get topped with smoky bacon, salty cheese, and a drizzle of balsamic for a sweet and savory finish.
Preheat oven to 400°F (200°C) and set the rack in the center. Line a sheet pan with parchment paper or aluminum foil coated with cooking spray.
Cook the bacon in a dry skillet over medium heat, turning occasionally until crisp. Remove it from the pan, drain on paper towels, and chop into small pieces.
Rinse the Brussels sprouts under cold water, pat them dry, then trim the ends and cut them in half through the stem.
In a large bowl, toss the sprouts with olive oil, salt, and pepper until evenly coated.
Spread them out in a single layer on the baking sheet, cut side down, and roast for 15 minutes.
Remove from the oven and push the sprouts toward the center of the pan. Drizzle with balsamic vinegar, then sprinkle bacon and cheese over the top.
Return to the oven for another 10–15 minutes, until the sprouts are tender and the cheese is melted.
Taste and adjust seasoning with salt and pepper before serving.
