GRILLED CHEESE BRUNCH BAKE

Steps:

• Preheat oven to 350 degrees F (175 degrees C). Grease a 9x13-inch casserole dish with cooking spray.
• Spread an even layer of mayonnaise on one side of each slice of bread. Place 6 slices of bread mayonnaise-side down in a single layer at the bottom of the casserole dish.
• Bake in the preheated oven until lightly toasted, about 5 minutes. Remove from oven and top each slice of bread with 1 slice of Cheddar cheese. Cover with 6 more slices of bread, mayonnaise-side up.
• Bake in the preheated oven until bread is lightly toasted, about 5 minutes.
• Sprinkle 1/4 of the shredded Cheddar cheese on top. Arrange slices of ham on top; cover with another 1/4 of the shredded Cheddar cheese. Repeat with bacon slices, covering with another 1/4 of the shredded Cheddar cheese. Arrange last 6 slices of bread, mayonnaise-side up, on top.
• Whisk eggs, milk, salt, and black pepper together in a large bowl. Pour evenly over bread in the casserole dish. Sprinkle remaining 1/4 cup shredded Cheddar cheese on top. Cover with aluminum foil.
• Bake in the preheated oven until set, about 30 minutes.
• Remove aluminum foil and continue baking until cheese is bubbly and golden, 5 to 10 minutes more.
