Why You’ll Love this Ham and Cheese Egg Bake
A traditional omelette or omelet is a dish made from beaten eggs, which are fried with butter or oil in a frying pan (without stirring the eggs as they cook). The omelet is typically folded around fillings such as chives, vegetables, mushrooms, meat (often ham or bacon), cheese, or a combination of these.
With this recipe, however, you get all of the classic flavors and ingredients of a ham and cheese omelette, but the dish is baked in the oven rather than fried in a skillet. That means that it’s easier to prepare, completely hands-off, and healthier (thanks to less oil and butter, no bread, and plenty of protein). The egg bake is also very versatile, as you can add just about any veggies, meat, and cheeses that you have on hand. It works well for holidays, brunches, and even weeknight dinners!
Ingredients for this Ham Egg Cheese Casserole
This is just a quick overview of the ingredients that you’ll need for a ham and cheese egg bake. As always, specific measurements and complete cooking instructions are included in the printable recipe box at the bottom of the post.
- Eggs: you can’t beat farm-fresh eggs! If you prefer to use fewer eggs and substitute with extra egg whites, see my note in the recipe below.
- Milk: use whole milk, 2% milk, or even half-and-half or heavy cream. You need some fat in the liquid to make an egg custard with the best texture and flavor.
- Seasoned salt: such as Lawry’s brand, for seasoning the egg casserole.
- Ham: use leftover ham from a previous meal, or purchase a ham steak, diced ham, or even deli ham at the grocery store.
- Cheese: we love the classic combination of ham with sharp cheddar cheese, but you can substitute with just about any good melting cheese. Other nice options include Swiss, Pepper Jack, Monterey Jack, Colby Jack, Gouda, and mozzarella cheese.
- Onion: for a touch of sweet and savory flavor.
How to Bake an Omelet
The puffy, cheesy, golden brown breakfast casserole could not be easier to prepare! You’ll find detailed directions in the recipe card below, but here’s the quick version:
- Whisk eggs, milk, and seasoned salt.
- Sprinkle ham, cheese, and onion into the uncooked egg mixture; stir to combine.
- Pour the egg mixture into a greased 8-inch square dish.
- Bake the omelet in a 350°F oven for 40-45 minutes.
- Slice into squares, transfer to a serving plate, and garnish with fresh herbs.

Preparation and Storage Tips
- Storage: Unlike a quiche, there’s no crust to get soggy, so a leftover baked omelet keeps very well in the fridge. Store the ham and cheese egg bake in an airtight container in the refrigerator for 3-4 days. It’s a nice way to prep ahead for busy weekday breakfasts!
- How to Freeze: Let the casserole cool to room temperature. Slice into squares, wrap each individual square in plastic wrap, and then again in foil. The tightly wrapped squares will keep in the freezer for up to 3 months. Thaw in the refrigerator overnight.
- How to Reheat: To reheat the entire casserole, let the dish sit on the counter for at least 30-60 minutes to come to room temperature. Warm in a 350°F oven just until heated through, about 20 minutes. You can also reheat individual slices in the microwave for about 1 minute, or until warmed through.
Recipe Variations
- To serve a larger group, double all of the ingredients and bake the omelet in a 9 x 13-inch baking dish. You will likely need to increase the baking time by 5-10 minutes to account for the larger casserole.
- Add vegetables: stir in just about any sauteed vegetables that you like. Good options include sweet bell peppers, zucchini, tomatoes, mushrooms, and broccoli. Spinach is also a nice addition to the egg bake, and you don’t need to cook it first.
- Try herbs: mix fresh herbs right into the eggs for even more flavor. Good options include chopped fresh parsley, chives, thyme, rosemary, and basil. Sliced green onions are also a nice addition.
- Almost any good melting cheese will work in this omelette. Instead of the sharp cheddar, try Swiss, Colby, Colby Jack, Monterey Jack, Pepper Jack, or Gouda.
- Whisk some Dijon mustard or dry mustard into the egg mixture for a little bit of a zesty bite. Garlic powder, onion powder, cayenne, and/or ground black pepper are also great options, too.
- Instead of the diced ham, use an equal amount of cooked bacon or cooked, crumbled sausage.
Tips for the Best Ham and Cheese Egg Bake Recipe
- Use leftover ham (such as holiday extras from Easter or Christmas), or just purchase ham at the grocery store to use in this recipe. You can buy a ham steak and dice it yourself at home, or pick up a package of pre-diced ham and avoid the extra prep. Even sliced ham from the deli counter will work!
- Dice the onion into very fine pieces so that it softens in the oven. Larger chunks of onion may still be crisp at the end of baking, and nobody wants to bite into a crunchy onion!
- Use whole milk or at least 2% milk for the best texture. You need some fat to make a good egg custard, so even half-and-half or heavy cream will work for a richer, more decadent dish.
- Don’t skip the Lawry’s seasoned salt. This single ingredient is an easy way to add tons of flavor to the omelet, since it includes a blend of seasonings like paprika, onion, and garlic. The omelet just doesn’t taste quite as good without it!
