- 6 slices lower-sodium bacon
- 1/2 large white onion, diced
- 30 Brussels sprouts, halved lengthwise
- 2 cloves garlic, chopped
- salt and ground black pepper to taste
- 2 tablespoons grated Parmesan cheese, or to taste (optional)
- Place bacon in a large skillet and cook over medium-high heat, turning occasionally, until evenly browned, about 10 minutes. Drain the bacon slices on paper towels, retaining grease in the skillet. Crumble bacon.
- Cook and stir onion in the bacon grease over medium heat until translucent, about 5 minutes. Add Brussels sprouts; cook and stir until Brussels sprouts are lightly browned, about 5 minutes. Season Brussels sprouts mixture with salt and pepper.
- Sprinkle bacon over Brussels mixture and stir. Remove skillet from heat, transfer Brussels sprouts mixture to a serving bowl, and sprinkle with Parmesan cheese.
