Ingredients Breakdown
- Eggs
Eggs are the foundation of this casserole, providing protein, richness, and structure. Use large eggs for the best consistency and flavor. You can also try using egg substitutes if needed. - Ham
Diced ham adds savory flavor and texture to the casserole. You can use leftover ham from a previous meal or buy pre-diced ham from the store. If you prefer, swap ham for bacon or sausage for a different flavor profile. - Cheese
Cheddar cheese is the classic choice for this casserole, offering a sharp, creamy flavor. Feel free to experiment with other cheeses like mozzarella, gouda, or even a cheese blend for added richness. - Bread
Stale bread works best for casseroles as it absorbs the egg mixture, giving the dish its signature custard-like texture. You can use white, whole wheat, or sourdough bread. If you’re gluten-free, substitute gluten-free bread for the same results. - Milk or Cream
Milk or heavy cream provides creaminess to the casserole. If you’re looking to cut calories, you can use a lower-fat milk or a non-dairy alternative like almond or oat milk. - Green Onion
For added freshness and a mild onion flavor, sprinkle chopped green onions on top of the casserole before baking. You can also mix some into the egg mixture for an added flavor boost. - Seasonings
A pinch of salt, pepper, garlic powder, and mustard (optional) brings everything together, but feel free to customize with your favorite seasonings or fresh herbs.

Step-by-Step Instructions
- Preheat the Oven
Begin by preheating your oven to 350°F (175°C). Grease a 9×13-inch casserole dish with butter or cooking spray to ensure your casserole doesn’t stick. - Prepare the Bread
Cut your bread into cubes and layer them evenly in the bottom of the prepared casserole dish. If you’re using stale bread, you may want to toast it lightly first to prevent it from becoming too soggy. - Cook the Ham
In a skillet over medium heat, cook the diced ham for 3-5 minutes until it’s slightly browned. This will enhance its flavor and make it a bit crispier. Once cooked, scatter the ham evenly over the bread cubes. - Whisk the Eggs and Dairy
In a large mixing bowl, whisk together the eggs, milk (or cream), salt, pepper, garlic powder, and mustard (if using). Pour this mixture evenly over the bread and ham in the casserole dish. Press down gently with a spatula to ensure the bread absorbs the liquid. - Add Cheese and Bake
Sprinkle the shredded cheddar cheese evenly over the casserole. Cover the dish with aluminum foil and bake for 25-30 minutes. After that, remove the foil and bake for another 10-15 minutes until the top is golden and bubbly, and a knife inserted into the center comes out clean. - Let It Rest
Once the casserole is done, remove it from the oven and let it rest for about 5-10 minutes. This allows the flavors to set and makes it easier to cut into servings. - Serve
Slice the casserole into squares, garnish with chopped green onions, and serve hot. Enjoy with a side of fresh fruit, a green salad, or your favorite breakfast drink.
Tips and Variations
- For a Creamier Version: Swap out some of the milk for heavy cream for an even richer casserole.
- Veggie Add-Ins: Add sautéed onions, bell peppers, or spinach to the casserole to make it even more hearty and flavorful.
- Gluten-Free Version: Use gluten-free bread and double-check that all other ingredients are gluten-free, especially the ham and seasonings.
- Meat Alternatives: If you’re not a fan of ham, feel free to swap in cooked sausage, bacon, or even leftover turkey.
- Make It Spicy: Add a diced jalapeño or a dash of hot sauce to the egg mixture for some heat.
Serving Suggestions
- Side Options: This casserole pairs perfectly with a light green salad, roasted potatoes, or fresh fruit for a balanced breakfast or brunch spread.
- Garnish: Top with freshly chopped herbs like parsley or basil for a pop of color and extra flavor.
- Pairing Drinks: Serve with a fresh orange juice, coffee, or a light tea to complement the savory flavors of the casserole.
Storage and Reheating Instructions
- Fridge: Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or oven.
- Freezer: This casserole freezes beautifully. Let it cool completely, then wrap it tightly with plastic wrap or foil and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
- Reheating: To reheat, simply warm individual servings in the microwave for 1-2 minutes or bake in the oven at 350°F (175°C) for 15 minutes until heated through.
Recipe Notes
- Make Ahead: You can prepare this casserole the night before. Assemble everything in the casserole dish, cover, and refrigerate overnight. In the morning, just pop it in the oven and bake as directed.
- Shredded Cheese: Freshly shredded cheese melts better than pre-shredded, so if you can, shred it yourself for a smoother texture.
- Slow Cooker Version: You can also make this casserole in a slow cooker. Follow the same steps for preparation, but cook it on low for 3-4 hours or high for 2 hours.
