1. Preheat oven to 400 degrees. Halve brussels sprouts through core; set aside.

2. Place bacon in a wide, ovenproof skillet and cook over medium heat, stirring occasionally, until almost crisp, about 4 minutes. Using a slotted spoon, transfer bacon to a paper towel-lined plate; set aside.

3. Drain most of the fat from skillet and add brussels sprouts, cut side-down. Increase heat to medium-high and cook until sprouts begin to sizzle. Transfer skillet to oven and roast until sprouts are deep brown in color, about 8 minutes. Shake skillet to redistribute sprouts, and continue roasting until bright green and tender, 10 to 15 minutes more.

4. Return skillet to stovetop and turn heat to medium. Stir in butter and bacon; season with salt and pepper. Toss sprouts to coat.

5. Divide kimchi among 4 shallow bowls, using the back of a spoon to spread out kimchi so it covers the bottom of each bowl. Divide brussels sprouts evenly among bowls, arranging on top of kimchi. Garnish with carrots and serve.
