Ingredients needed for this Ham, Swiss, and Egg Breakfast Bake

Eggs – 8 medium (6 large will also work). Milk – 1/2 cup. Adding milk helps make the eggs fluffy; use 1% or whatever you have (even half-and-half). Garlic powder – 1/2 tsp for a bit of extra flavor. Canned biscuits – a 16 oz can (butter-flavored, regular, or homestyle). You can tear or cut them up. Ham – about 2 cups thick diced ham (leftover cooked ham or Canadian bacon both work). Swiss cheese – 1 cup shredded Swiss (or substitute another melting cheese if preferred).

How to make this ham and cheese breakfast casserole

Step 1: In a mixing bowl, crack the eggs and add the milk and garlic powder. Whisk until blended.

Step 2: Tear or cut the biscuits into pieces and arrange them in the bottom of a greased 9×13-inch (or slightly smaller) baking dish. Scatter the diced ham evenly over the biscuits.

Step 3: Pour the egg mixture over the biscuits and ham, pressing gently so the biscuits absorb some of the liquid.

Step 4: Sprinkle the shredded Swiss cheese over the top and bake at 350°F (175°C) for 35–40 minutes, or until the eggs are set and the biscuits are golden brown.

Let the casserole rest a few minutes, then slice and serve warm.

Additions & substitutions

• Swap the Swiss for white cheddar, mild cheddar, or pepper jack for a different flavor profile.
• Use other cooked meats like bacon, turkey bacon, or pork sausage if you prefer.
• Add diced peppers and onions for extra color and texture.

Can you make this the night before?

Yes—this bake can be assembled and refrigerated overnight. If you do, the baking time may be a little longer since the casserole starts cold. Cover the dish and chill, then bake from chilled until set and golden.
