Ingredients For Ham And Cheese Breakfast Casserole
Eggs: The base of the casserole, providing structure and richness.
Milk: Adds creaminess and helps to bind the ingredients together.
Shredded cheddar cheese: Gives a sharp, cheesy flavor and melts beautifully.
Diced ham: Adds a savory, meaty element to the dish.
Salt: Enhances the overall flavor of the casserole.
Black pepper: Adds a touch of heat and depth to the flavor profile.
Technique Tip for This Recipe
When preparing this ham and cheese breakfast casserole, ensure that the eggs and milk are thoroughly whisked together to create a uniform mixture. This will help the casserole set evenly and achieve a consistent texture. Additionally, consider using a mix of cheddar cheese and another type of cheese, such as Monterey Jack, for a more complex flavor profile. To prevent the casserole from sticking, make sure to generously grease the baking dish with butter or a non-stick spray.

How to Store / Freeze This Breakfast Casserole
Allow the casserole to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
For short-term storage, transfer the casserole to an airtight container or cover the baking dish tightly with plastic wrap or aluminum foil. Store it in the refrigerator for up to 3-4 days.
If you plan to freeze the casserole, cut it into individual portions. This makes it easier to reheat only what you need.
Wrap each portion tightly with plastic wrap, then place them in a resealable freezer bag or an airtight container. Label with the date to keep track of freshness.
For best results, consume frozen casserole within 2-3 months. Beyond this period, the texture and flavor may start to degrade.
To reheat from the refrigerator, preheat your oven to 350°F (175°C). Place the casserole in an oven-safe dish and cover with foil. Heat for 20-25 minutes or until warmed through.
For reheating from frozen, you have two options:
- Thaw in the refrigerator overnight, then follow the reheating instructions for refrigerated casserole.
- Reheat directly from frozen by placing the casserole in an oven-safe dish, covering with foil, and baking at 350°F (175°C) for 45-60 minutes, or until heated through.
If you prefer using a microwave, place a portion of the casserole on a microwave-safe plate. Cover with a microwave-safe lid or another plate to retain moisture. Heat on medium power for 2-3 minutes, checking and stirring halfway through, until hot.
Always ensure the casserole reaches an internal temperature of 165°F (74°C) when reheating to ensure food safety.
How to Reheat Leftovers
Oven Method:

Microwave Method:
- Cut a portion of the casserole and place it on a microwave-safe plate.
- Cover the plate with a microwave-safe lid or another plate to retain moisture.
- Heat on medium power for 2-3 minutes, checking halfway through to ensure even heating.
- If needed, continue heating in 30-second intervals until the casserole is hot.
Stovetop Method:
- Place a non-stick skillet over medium heat.
- Add a small amount of butter or olive oil to the skillet.
- Cut the casserole into slices and place them in the skillet.
- Cover the skillet with a lid to help retain heat and moisture.
- Heat for about 5-7 minutes, flipping halfway through, until the casserole is warmed through.
Air Fryer Method:
- Preheat your air fryer to 350°F (175°C).
- Place the casserole slices in the air fryer basket, making sure they are not overlapping.
- Heat for 5-7 minutes, checking halfway through to ensure even heating.
