Preheat oven 425 F.
In a large skillet over medium heat, cook the bacon until fully cooked. Remove the bacon from the pan and set it aside (but keep the bacon grease).
Next, add the garlic to the pan with the bacon grease, and fry for 1 minute. Remove and set aside.
Add the brussels sprouts into a cast iron pan or baking sheet, and toss them with the bacon grease, balsamic vinegar, garlic, salt, and black pepper. Mix until the sprouts are fully coated.
Roast the brussels sprouts in the oven, uncovered, for about 20-25 minutes or until tender, but be sure to stir occasionally!
Remove from the oven, and toss in the cooked bacon.
Serve & enjoy!
