Cheesy Brussels Sprout Bake
- Preheat oven to 375°. In a large oven-safe skillet over medium heat, cook bacon until crispy, 8 minutes. Drain on a paper towel-lined plate, then chop. Discard bacon fat.
- Return skillet to medium heat and melt butter. Add shallots and Brussels sprouts and season with salt and cayenne. Cook, stirring occasionally, until tender, about 10 minutes.
- Remove from heat and drizzle with heavy cream, then top with both cheeses and bacon.
- Bake until cheese is bubbly, 12 to 15 minutes. (If your cheese isn't golden, switch oven to broil and broil 1 minute.)
