Step‑by‑Step Instructions for Ham and Cheese Breakfast Casserole
Step 1: Prepare the Ingredients
Begin by cubing the day-old bread and dicing the ham into bite-sized pieces. Shred the cheese using a box grater or a food processor, ensuring it’s fluffy and ready to melt. This step sets a solid foundation for your Ham and Cheese Breakfast Casserole, blending texture and flavor together beautifully.
Step 2: Create the Egg Mixture
In a large mixing bowl, whisk together the eggs, milk, mustard powder, salt, and pepper until well combined and frothy. This egg mixture is critical as it binds all your ingredients together and adds richness to the casserole. Aim for a smooth consistency and set it aside while you arrange the layers next.
Step 3: Assemble the Casserole
Grease a 9x13-inch baking dish with cooking spray or butter. Layer the cubed bread evenly across the bottom, followed by a generous sprinkle of diced ham. Next, add the shredded cheese in an even layer over the ham, ensuring every bite will be cheesy and delicious. This careful layering enhances the flavors of the Ham and Cheese Breakfast Casserole.
Step 4: Pour the Egg Mixture
Carefully pour the egg mixture over the layered bread, ham, and cheese, making sure to cover everything evenly. With a spatula or your hands, gently press down on the layers to help the bread absorb the custard-like mixture. This process is crucial for achieving the perfect texture in your casserole, ensuring the bread gets beautifully soaked.
Step 5: Allow to Rest
Let the assembled casserole sit for about 10 minutes at room temperature so the bread can absorb the liquid fully. For those preparing in advance, cover the dish and refrigerate overnight. This gives the flavors time to meld, making your Ham and Cheese Breakfast Casserole even more delicious when baked.
Step 6: Preheat and Bake
Preheat your oven to 350°F (175°C) while the casserole rests. Once ready, place the dish in the oven and bake for about 45 minutes, or until the top is golden brown and the eggs are set. You’ll know it’s done when it puffs slightly and a toothpick inserted comes out clean, filling your kitchen with delightful aromas.
Step 7: Cool and Serve
After baking, remove the casserole from the oven and let it cool for about 5-10 minutes. This waiting time helps the casserole firm up a bit, making it easier to cut into squares. Serve warm and enjoy the heartwarming flavors of your Ham and Cheese Breakfast Casserole!

Tips for the Best Ham and Cheese Breakfast Casserole
-
Use Stale Bread: Day-old bread is best for soaking up the egg mixture. Fresh bread can result in a soggy casserole, so stick to the plan!
-
Don't Rush the Soak: Allowing your casserole to rest for at least 10 minutes (or overnight) is crucial. This helps the bread absorb all the delicious flavors, making your Ham and Cheese Breakfast Casserole truly exceptional.
-
Experiment with Cheese: While cheddar and mozzarella are classic choices, try incorporating Gruyère or pepper jack for a unique twist. Cheese can elevate the dish and offer varied taste profiles!
-
Avoid Overcrowding: When layering ingredients, spread them evenly. This ensures that each bite is packed with that savory ham and gooey cheese goodness!
-
Check for Doneness: To avoid an undercooked casserole, use a toothpick to test if the eggs are set. It should come out clean, signaling it’s perfectly baked!
Make Ahead Options
Getting a head start on your Ham and Cheese Breakfast Casserole is a great way to save time on busy mornings! You can prepare the entire casserole up to 24 hours in advance by following the assembly steps and covering it tightly before placing it in the refrigerator. Allowing it to sit overnight not only saves valuable time but also enhances the flavors as they meld together. When you're ready to bake, simply preheat your oven to 350°F (175°C), take the casserole out of the fridge while the oven heats (so it’s not too cold), and bake for about 45 minutes. This preparation method ensures your dish is just as delicious and comforting, making mornings much more manageable!
