01 - Set the oven to 425°F and prepare a baking sheet by lining it with parchment paper or foil.
02 - In a large mixing bowl, toss Brussels sprouts with olive oil, kosher salt, black pepper, and garlic powder if using, ensuring even coverage.
03 - Spread the Brussels sprouts cut side down on the prepared baking sheet; evenly distribute the chopped turkey bacon over them.
04 - Roast for 20 to 25 minutes, stirring once halfway through, until sprouts are golden and tender and turkey bacon is crispy.
05 - Remove from oven and, if desired, drizzle with balsamic glaze or fresh lemon juice. Serve warm.
