Why this recipe works
- High-heat roasting brings out the natural sweetness of Brussels sprouts while creating crisp, browned edges.
- Bacon adds rich, savory fat and crunch that pairs perfectly with the sprouts.
- Minimal ingredients keep the flavors focused and the carb count low — ideal for keto and low-carb diets.
Ingredients
- 1 lb (about 450 g) Brussels sprouts, trimmed and halved
- 6 slices bacon (about 72 g), cut into 1-inch pieces
- 2 tablespoons olive oil (or 2 tbsp reserved bacon fat)
- 1/2 teaspoon kosher salt (adjust to taste)
- 1/4 teaspoon freshly ground black pepper
- 2 tablespoons grated Parmesan cheese (optional; adds savory umami)
- 1 teaspoon lemon zest or 1 tablespoon lemon juice (optional, for brightness)
- Pinch of red pepper flakes (optional, for heat)
Directions
- Preheat oven: Heat to 425°F (220°C). Use a rimmed baking sheet for best airflow and browning.
- Prepare Brussels sprouts: Trim the stem ends and halve each sprout. Pat dry — removing surface moisture helps them crisp.
- Toss with fat and seasoning: In a large bowl, toss the halved sprouts with olive oil (or bacon fat), salt, and pepper until evenly coated.
- Add bacon: Two approaches:
- Raw-bacon method (easier): Scatter raw bacon pieces across the sheet with the sprouts so the bacon renders during roasting.
- Crisp-first method (extra-crispy bacon): Fry or bake the bacon separately until nearly crisp, drain on paper towels, reserve a tablespoon of bacon fat, then toss with the sprouts and add chopped bacon toward the end of roasting.
- Roast: Spread sprouts and bacon in a single layer on the sheet pan. Roast 20–30 minutes, stirring or flipping once halfway through, until sprouts are deeply browned at the edges and bacon is crisp.
- Finish: Remove from oven. Toss with Parmesan and lemon zest or juice if using. Taste and adjust salt and pepper.
- Serve immediately for best texture.
Tips for perfect roasted Brussels sprouts with bacon
- Don’t overcrowd the pan. Give sprouts space to brown — you may need two pans for large batches.
- Dry the sprouts well after washing to avoid steaming.
- For extra caramelization, roast at 425–450°F and watch closely the last 5 minutes to prevent burning.
- To lower carbs further, skip any sweet glazes, balsamic reductions, or maple finishes.
Serving suggestions and pairings
- Serve alongside roasted chicken, pork chops, or salmon.
- Add toasted pecans or walnuts for crunch (note: nuts add carbs).
- Top with crumbled goat cheese or extra Parmesan for richness.
Storage and reheating
- Refrigerate leftovers in an airtight container for up to 3–4 days.
- Reheat in a 375°F oven for 8–10 minutes or re-crisp in a skillet over medium heat. Microwaving will soften the texture.
