01 - Preheat the oven to 425°F. Line a baking sheet with parchment paper.
02 - In a large bowl, toss the Brussels sprouts with olive oil, salt, pepper, and garlic powder until evenly coated.
03 - Spread the Brussels sprouts in a single layer on the prepared baking sheet. Scatter the chopped turkey bacon evenly over the sprouts.
04 - Roast for 20 to 25 minutes, stirring once halfway through, until the Brussels sprouts are golden brown and crispy on the edges, and the turkey bacon is cooked through.
05 - Remove from the oven. Transfer to a serving dish and sprinkle with Parmesan cheese and fresh parsley if desired. Serve hot.
