1. Bring a large pot of salted water to a boil. Blanch the Brussels sprouts in the boiling water for 2 to 3 minutes. Drain.
2. Meanwhile, cook the bacon in a large saute pan over medium heat until the fat has rendered out and the bacon is crispy and brown, 6 to 7 minutes. Add the Brussels sprouts to the pan in a single layer, cut-side down, and cook, without stirring, until the sprouts are lightly browned, about 3 minutes. Stir and continue to cook until the sprouts are browned on the other side, 2 minutes more. Season with salt and pepper.
3. Divide the bacon-sprout mixture among 4 plates and serve immediately.
