How to Make Ham Egg and Cheese Casserole – Step by Step

Ingredient measurements and full instructions are located in the recipe card below.

Step 1: Add cheese to baking dish

Combine the cheeses in a large bowl. Place 1/2 in the bottom of the prepared baking dish.

Step 2: Cook vegetables

Cook the green onions, bell pepper, green chiles, and drained mushrooms in the melted butter until tender. Spread evenly over the top of the cheeses in the baking dish.

Step 3: Layer ham and cheese

Sprinkle the ham and remaining cheese over the top.

Step 4: Add remaining ingredients and bake

In a large bowl, whisk together the flour, milk, parsley, and eggs. Pour over the top of the casserole. Bake in the preheated oven for 35-45 minutes.

Tips and Notes

  • Meat options: feel free to swap the ham with whatever type of cooked breakfast meat you like best. Chopped bacon, breakfast sausage, or Canadian bacon would all work great.
  • Vegetable swaps/addtions: you can use whatever kind of veggies you like or have on hand. Spinach, fresh mushrooms, diced yellow onion, or even chopped broccoli are great additions or swaps.
  • Vegetarian and Gluten free options: to make this breakfast casserole vegetarian, simply leave out the ham and consider adding an additional vegetable (like spinach) in its place. For a gluten free option, replace the all purpose flour with gluten free flour (I like Bob’s Red Mill).

FAQs

Can this be made in advance?

Yes and that’s why I love it for Christmas morning breakfast! Simply prepare as directed up until the baking step. Cover the casserole with plastic wrap and refrigerate overnight. In the morning, remove the plastic wrap and bake as directed.

Can Ham Egg and Cheese Casserole be frozen?

Yes! Prepare as directed using a freezer safe baking dish (like a disposable aluminum foil pan). Cover tightly with both plastic wrap and aluminum foil and freeze for up to three months. Allow the casserole to thaw overnight in the refrigerator before baking as directed in the morning.

How to store leftovers?

Any leftover breakfast casserole can be stored in an airtight container in the fridge for up to three days.
