Trim the bottom of each sprout and remove any discolored leaves. Cut the Brussels sprouts in half.
Crisp the bacon in a large skillet over medium-high heat. Set the bacon aside, leaving the bacon grease in the pan.
Add the Brussels sprouts to the pan, turning them face-down if possible. Reduce the heat to medium and cook sprouts for 10-12 minutes or until tender-crisp, stirring occasionally.
Season the Brussels sprouts with salt and pepper, then toss with balsamic vinegar and the cooked bacon.
Notes
Store leftover Brussels sprouts in a covered container in the fridge for up to 5 days.
Reheat them in the microwave, air fryer, or on the stovetop.
For longer storage, freeze them in a zippered bag for up to a month.
