This Ham Breakfast Casserole is a tasty way to start your day! It features hearty eggs, savory ham, and fluffy bread all baked together for a warm breakfast treat.
I love how easy it is to whip up, especially on busy mornings. Just mix it up, pop it in the oven, and enjoy a delicious breakfast with minimal fuss. Perfect for sharing too!
Key Ingredients & Substitutions
Eggs: Large eggs are the backbone of this casserole. They help bind everything together. If you’re looking for a healthier option, you can use egg whites instead – just adjust the amount to equal about six eggs.
Milk: Whole milk gives the casserole a rich flavor and creamy texture. You can substitute low-fat milk or even almond milk if you’re avoiding dairy, just keep an eye on the end texture.
Cubed Bread: Day-old bread is perfect because it absorbs the egg mixture without getting mushy. If you don’t have stale bread, toast fresh bread for a few minutes until it’s slightly dry. You can also use croissants or bagels for a fun twist!
Ham: Diced cooked ham adds a great savory flavor. If you don’t have ham, cooked bacon or sausage also works well, or you can use a vegetarian substitute like mushrooms or spinach for a meat-free option.
Chedder Cheese: Shredded cheddar gives that beautiful melty texture. You might also use Monterey Jack or pepper jack for a bit of spice. Always feel free to mix your favorite cheeses in!
How Do I Ensure My Casserole Sets Perfectly?
Getting the right texture is key. You want the egg mixture to thoroughly soak the bread. Follow these steps for the best results:
- Mix the egg and milk well to incorporate air, which helps with fluffiness.
- Press the bread lightly into the egg mixture after pouring it over. This helps it soak evenly.
- Let the casserole sit for about 10 minutes before baking. This gives the bread time to absorb the mixture.
- Make sure to bake it until the center is firm and the edges are golden brown. This is crucial for a great texture!
Letting it rest after baking is also essential. It will set up a bit more and makes cutting easier. Enjoy your delicious casserole!

- 1/2 teaspoon black pepper
- 4 cups cubed bread (day-old or slightly stale is best)

How Much Time Will You Need?
This delicious Ham Breakfast Casserole takes about 15 minutes to prepare and about 45-50 minutes to bake. Overall, you’ll need around 1 hour to enjoy this warm, comforting dish that’s perfect for breakfast or brunch!
Step-by-Step Instructions:
1. Preheat Your Oven:
Get your oven preheated to 350°F (175°C). While it’s warming up, grease or spray a 9×13-inch baking dish to prevent sticking.
2. Prepare the Egg Mixture:
In a large bowl, whisk together the eggs, milk, salt, black pepper, and dry mustard (if using). Make sure everything is well combined and fluffy.
3. Assemble the Ingredients:
Now, spread the cubed bread evenly in the prepared baking dish. This will be the base for your casserole.
4. Add the Ham:
Sprinkle the diced cooked ham evenly over the bread cubes, making sure every bite will have some ham.
5. Cheese It Up:
Next, sprinkle the shredded cheddar cheese over the ham and bread. The cheese will melt beautifully as it bakes!
6. Pour the Egg Mixture:
Pour the egg mixture evenly over the bread, ham, and cheese. Press gently to make sure the bread is nicely submerged in the egg mixture.
7. Let It Soak:
Allow the casserole to sit for about 10 minutes. This waiting time helps the bread soak up all that delicious egg goodness.
8. Bake the Casserole:
Bake uncovered for 45-50 minutes. You’ll know it’s done when the center is set, and the top is golden brown. Keep an eye on it towards the end!
9. Cool and Cut:
Once it’s out of the oven, let it sit for about 5 minutes. This makes it easier to cut into squares without falling apart.
10. Serve and Enjoy:
Garnish with fresh parsley if you like, and serve it warm. Enjoy your hearty and delicious Ham Breakfast Casserole!
Can I Use Different Types of Bread for This Casserole?
Absolutely! While day-old bread works best for absorbing the egg mixture, you can use any type of bread you have on hand. Baguette, croissants, or even bagels can add unique flavors and textures.
Can I Substitute the Ham for Another Protein?
Yes! If you don’t have ham or prefer a different protein, cooked bacon, turkey, or sausage can work well. For a vegetarian option, consider using sautéed vegetables or cooked plant-based sausage. Just ensure they are pre-cooked for the best flavor!
How Can I Store Leftovers?
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm in the microwave or bake in the oven at 350°F (175°C) for about 15-20 minutes, until heated through.
Can I Make This Casserole Ahead of Time?
Yes! You can assemble the casserole the night before and store it covered in the fridge. In the morning, just pop it in the oven and bake as directed. This makes for a convenient breakfast option!
