Ham & Cheese Breakfast Casserole: A Warm, Easy Make-Ahead Morning Recipe

Ham & Cheese Breakfast Casserole is a comforting baked breakfast dish made with eggs, diced ham, melted cheese, bread or hash browns, milk, and simple seasonings. It is soft and fluffy in the center, golden on top, and full of savory flavor. This casserole is perfect for busy mornings, family brunch, holidays, meal prep, or anytime you want a filling breakfast without cooking each item separately.

The best thing about this recipe is that it can be prepared ahead of time. You can assemble it the night before, refrigerate it, and bake it in the morning. The result is a warm, cheesy, hearty breakfast that tastes homemade and satisfying.

Why This Breakfast Casserole Works

This casserole brings together classic breakfast ingredients in one dish. The eggs hold everything together, the ham adds a salty and savory flavor, and the cheese melts into the mixture to create a rich texture. Bread cubes or hash browns absorb the egg mixture and make the casserole filling and soft.

It is also very flexible. You can keep it simple with ham and cheddar, or add vegetables, herbs, potatoes, or different cheeses depending on what you have at home.

Ingredients

Main Ingredients

• 8 large eggs
• 1 ½ cups milk

• 2 cups shredded cheddar cheese
• 1 cup shredded mozzarella or Monterey Jack cheese
• 4 cups cubed bread, or 3 cups frozen hash browns
• ½ cup diced onion
• ½ cup diced bell pepper, optional
• 2 tablespoons melted butter
• 1 teaspoon salt
• ½ teaspoon black pepper
• ½ teaspoon garlic powder
• ½ teaspoon onion powder
• ½ teaspoon paprika
• 1 tablespoon chopped parsley or green onions, optional

Step 1: Prepare the Baking Dish

Preheat your oven to 350°F / 175°C.

Grease a 9×13 inch baking dish with butter or non-stick spray. Make sure the bottom and sides are coated well so the casserole does not stick.

A glass or ceramic baking dish works well because it holds heat evenly and allows the casserole to bake gently.

Step 2: Prepare the Bread or Hash Browns

For a classic breakfast casserole, use cubed bread. Slightly dry bread works best because it absorbs the egg mixture without becoming mushy. You can use white bread, brioche, sourdough, sandwich bread, or French bread.

Cut the bread into small cubes and spread them evenly in the baking dish.

For a potato-style casserole, use frozen hash browns instead. Thaw them first and squeeze out extra moisture. This helps prevent the casserole from becoming watery.

Step 3: Add the Ham

Dice the cooked ham into small pieces.

Scatter the ham evenly over the bread cubes or hash browns. Try to spread it across the whole dish so every slice has enough ham.

This recipe is a great way to use leftover holiday ham, deli ham, or thick-cut ham slices.
