Preheat the oven: Heat to 425°F (220°C). Place a large, rimmed sheet pan in the oven while it preheats to get it hot. A hot pan helps with browning.
Prep the sprouts: Trim the tough ends and remove any yellow leaves.
Slice sprouts in half through the core so they hold together. If you have very large sprouts, quarter them.
Season: In a large bowl, toss sprouts with olive oil, maple syrup, salt, and pepper. Add a pinch of red pepper flakes if you like heat.
Keep a little maple aside (about 1 teaspoon) for finishing, if desired.
Add bacon: Stir in chopped bacon so the pieces are evenly distributed. The bacon fat will render and help crisp everything up.
Arrange on the pan: Carefully remove the hot sheet pan from the oven. Spread the sprouts cut side down in a single layer, with the bacon scattered around.
Don’t crowd the pan—use two pans if needed.
Roast: Cook for 20–25 minutes, stirring once around the 15-minute mark. You’re looking for deep browning on the cut sides and crisp bacon. If they need more color, give them another 3–5 minutes.
Finish: Toss with a small splash of balsamic or apple cider vinegar for brightness.
Add fresh thyme or rosemary if using. Taste and adjust salt and pepper.
Optional add-ins: Sprinkle toasted nuts for crunch or finish with a squeeze of lemon and a light drizzle of the reserved maple for a glossy sheen.
Serve hot: Transfer to a warm platter and serve right away for the crispiest texture.
