Preheat and prep bacon. Preheat your oven to 400°F. While the oven heats, cook 3 slices bacon in a skillet over medium heat until crispy, about 8-10 minutes. Transfer to a paper towel-lined plate to drain, then chop into small pieces. Set aside.
Prepare the baking sheet. Line a large rimmed baking sheet with parchment paper. This prevents sticking and makes cleanup easier.
Prep the Brussels sprouts. Wash and dry the 1 pound Brussels sprouts thoroughly. Trim the stem ends and remove any yellowed outer leaves. Cut each sprout in half lengthwise through the stem.
Season the sprouts. In a large mixing bowl, combine the halved Brussels sprouts, 2 tablespoons olive oil, 2 tablespoons maple syrup, 1 teaspoon garlic powder, 1 teaspoon salt, and ¼ teaspoon black pepper. Toss thoroughly until every sprout is evenly coated.
Arrange for roasting. Spread the seasoned Brussels sprouts on the prepared baking sheet in a single layer, placing them cut-side down. Leave space between each piece for proper air circulation.
Roast until crispy. Place the baking sheet in the preheated oven and roast for 20-25 minutes. The sprouts are done when they're fork-tender and the edges are deeply browned and crispy. For extra crispiness, broil for the final 2-3 minutes, watching carefully to prevent burning.
Add bacon and serve. Remove from the oven and immediately toss with the chopped crispy bacon. Transfer to a serving dish and garnish if desired. Serve hot.
Notes
Best Brussels sprouts selection: Look for firm, bright green sprouts with tightly packed leaves. Avoid any that are yellowing or have loose leaves, these are past their prime.
Temperature is key: Don't reduce the oven temperature thinking it will prevent burning. The high heat (400°F) is essential for caramelization and crispy edges.
Bacon timing: Add bacon after roasting, not before. Adding it too early can make it soggy instead of crispy.
Serving size: This recipe serves 4 as a side dish. For a main course or larger gathering, double the recipe and use two baking sheets.
