Preheat the oven to 350 degrees F (175 degrees C). Line a baking sheet with aluminum foil.

Scoop out the bread from the center of the baguette pieces, or make a depression by pushing the centers down with your fingers. Place bread boats on the prepared baking sheet.

Whisk eggs in a medium bowl until blended. Add Cheddar cheese, onion, bell pepper, and 1/2 of the bacon; mix to combine. Pour egg mixture into the bread boats.

Bake in the preheated oven until until the egg mixture is fully set, 20 to 25 minutes. Broil for a few minutes if egg is not fully set; watch carefully to make sure edges of the bread don't burn.

Sprinkle with remaining bacon and serve.
