Why This Recipe Works
Boiling the potatoes first ensures they become perfectly tender while baking instead of remaining firm. Sautéing the onions, peppers, and ham develops rich flavor before they're layered into the casserole.
The eggs and milk create a light custard that surrounds every ingredient, while the cheddar cheese melts into a golden topping that holds everything together.
The result is a breakfast casserole that's fluffy, creamy, cheesy, and satisfying.

Instructions
Step 1: Prepare the Oven
Preheat oven to 375°F (190°C).
Grease a 9x13-inch baking dish with butter or nonstick cooking spray.
Step 2: Cook the Potatoes
Bring a large pot of salted water to a boil.
Add diced potatoes and cook for 8–10 minutes, or until just fork tender.
Drain thoroughly and allow excess moisture to evaporate.
Step 3: Prepare the Egg Mixture
In a large mixing bowl whisk together:
- Eggs
- Milk or cream
- Salt
- Black pepper
Whisk until completely smooth and slightly frothy.
Step 4: Cook the Ham and Vegetables
Heat butter in a large skillet over medium heat.
Add:
- Diced onion
- Bell peppers
Cook for about 4 minutes, stirring occasionally until softened.
Add diced ham and cook another 2 minutes, allowing the edges to lightly brown.
Remove from heat.
Step 5: Assemble the Casserole
Spread the cooked potatoes evenly across the bottom of the prepared baking dish.
Top with the ham and vegetable mixture.
Pour the egg mixture evenly over the casserole, allowing it to settle into every layer.
Sprinkle shredded cheddar cheese generously over the top.
Step 6: Bake
Bake for 25–30 minutes, or until:
- Eggs are fully set
- Cheese is melted
- Top is golden brown
- Edges are lightly crispy
Step 7: Rest and Serve
Allow the casserole to cool for 5 minutes before slicing.
Garnish with parsley or chives if desired.
Serve warm.
Pro Tips for Success
Drain the Potatoes Well
Excess water can make the casserole watery.
Use Freshly Shredded Cheese
Fresh cheese melts smoother and creates a creamier texture.
Don't Overbake
Remove from the oven as soon as the eggs are set to keep the casserole fluffy.
Let It Rest
Five minutes of resting helps the casserole slice cleanly.
