5-Ingredient Baked Hash Brown Patty Casserole

This clever casserole turns frozen hash brown patties into the ultimate comfort-food shortcut. As it bakes, the patties transform—the tops turn tender and custard-like while the bottoms develop a golden, crispy crust. Combined with fluffy eggs, savory diced ham, and a generous blanket of sharp cheddar, every spoonful is hearty, cheesy, and downright irresistible. It's the perfect low-effort meal for brunch, a cozy weekend dinner, or even holiday mornings.

Ingredients

• 8–10 frozen hash brown patties

• 2 cups shredded sharp cheddar cheese (divided)

• 1½ cups cooked ham, diced

• 4 large eggs

• 2 cups milk (whole or 2%)

• Salt and freshly ground black pepper, to taste

Step-by-Step Directions

1. Build the base

Preheat your oven to 375°F and lightly grease a 9×13-inch baking dish. Arrange the frozen hash brown patties in a single, even layer across the bottom of the dish.

Pro tip: Avoid overlapping the patties—each one needs direct contact with the dish to crisp up properly underneath. Overlapping traps steam and leads to soggy spots.

2. Add the fillings

Sprinkle 1 cup of the shredded cheese evenly over the patties, followed by all of the diced ham. Spread the ham out so every bite gets a savory pop of meat.

3. Make the custard

In a medium bowl, whisk together the eggs, milk, salt, and pepper until smooth and fully combined. Slowly and gently pour the mixture over the entire casserole, making sure it seeps into every corner.

Pro tip: Pour in a steady stream over the back of a spoon or into one corner first—this keeps the cheese and ham layers from sliding around as the liquid spreads.

4. Top and bake

Sprinkle the remaining 1 cup of cheese over the top. Place the dish on the center rack and bake, uncovered, for 40–50 minutes.

Visual cue: The casserole is done when the center is fully set (no jiggle) and the top is puffed and lightly golden. If the cheese starts browning too quickly, loosely tent the dish with foil for the final 10 minutes.

5. Rest before serving

Remove the casserole from the oven and let it stand for about 10 minutes before slicing.

Pro tip: Resting allows the custard to firm up, so your slices hold their shape beautifully instead of turning into a runny mess. This also gives you time to toss a salad or brew some coffee!

Serving Suggestion

Serve warm with a side of fresh fruit, a simple green salad, or a dollop of sour cream. Leftovers (if there are any!) reheat beautifully in the microwave or toaster oven for a quick breakfast the next day.
