Preheat & Prep: Preheat oven to 350°F (175°C). Lightly grease six 6 oz ramekins with butter or nonstick spray. Place them on a baking sheet.
Combine Everything: In a large bowl, tear croissants into bite-sized chunks. Add the cooked turkey bacon and shredded cheese. Crack in the eggs, pour in the milk, season with salt and pepper, and gently mix until croissants are soaked.
Fill the Ramekins: Spoon the croissant mixture evenly into each ramekin. Press down lightly. Top with a bit more cheese if desired.
Bake at 350°F for 25-30 minutes, or until the tops are golden and the center is set. Let cool for 5 minutes before serving.
