How to Make 3-Ingredient Baked Breakfast
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease an 8×8-inch baking dish with butter or cooking spray.
Step 2: Prepare the Bread
Tear the bread into bite-sized pieces.
Spread the pieces evenly across the bottom of the prepared baking dish.
Step 3: Whisk the Eggs
Crack the eggs into a large mixing bowl.
Whisk thoroughly until the yolks and whites are completely combined.
Season with salt and pepper if desired.
Step 4: Pour Over the Bread
Slowly pour the egg mixture evenly over the bread.
Press the bread down gently so it absorbs the eggs.
Step 5: Add the Cheese
Sprinkle the shredded cheese evenly across the top.
If using optional add-ins, scatter them over the cheese.
Step 6: Bake
Bake for 25–30 minutes, or until the eggs are fully set and the cheese is golden brown.
A knife inserted into the center should come out clean.
Step 7: Cool Slightly
Allow the casserole to rest for 5 minutes before slicing.
Serve warm.
Expert Tips
Use day-old bread for the best texture.
Whisk the eggs well to create a lighter, fluffier casserole.
Don’t overbake or the eggs may become rubbery.
