Introduction

This Hash Brown Egg Casserole is a hearty and satisfying breakfast dish perfect for busy mornings or brunch gatherings. Combining crispy hash browns, savory ham, melted cheese, and a fluffy egg custard, it’s easy to prepare and sure to please the whole family.

A rectangular slice of egg casserole sits on a white plate with a raised edge, showing three distinct layers: the bottom layer is a soft, yellow egg base mixed with bits of ham; the middle layer has more dense chunks of ham and eggs, with melted cheese blended throughout; the top layer is golden yellow melted cheese with a slightly crispy texture and scattered green onion slices adding a fresh pop of color. A few green onion rings are also placed around the plate, complementing the dish. The plate rests on a white marbled surface, with a blurred white bowl of more green onions in the background.

Ingredients

8 precooked frozen hash brown patties (thawing is not necessary)
1 cup shredded sharp cheddar cheese
1 cup shredded Monterey Jack cheese
1 & 1/2 cups diced leftover ham (about 3/4 pound)
2 scallions, diced
9 large eggs
1 cup whole milk
1/2 teaspoon salt
1/2 teaspoon dry ground mustard (optional but recommended)
1/4 teaspoon garlic powder

Instructions

Step 1: Preheat the oven to 350 degrees F and grease a 9×13-inch baking dish.
Step 2: Arrange the frozen hash brown patties in a single layer in the prepared dish.
Step 3: Evenly sprinkle the shredded cheddar cheese, Monterey Jack cheese, diced ham, and scallions over the hash browns.
Step 4: In a large bowl, whisk together the eggs, whole milk, salt, dry ground mustard, and garlic powder until fully combined.
Step 5: Pour the egg mixture evenly over the layered ingredients in the baking dish.
Step 6: Cover the dish with foil and bake for 25 minutes. Then remove the foil and bake for an additional 20 minutes, or until the edges are golden and a knife inserted into the center comes out clean.
Step 7: Let the casserole cool for 5 to 10 minutes before cutting into portions and serving.

Tips & Variations

Use different cheeses such as mozzarella or pepper jack for a unique flavor.
Add diced bell peppers or mushrooms with the ham for extra vegetables.
If you prefer a spicier casserole, sprinkle in some crushed red pepper flakes or diced jalapeños.
For a vegetarian version, omit the ham and add cooked spinach or broccoli instead.

Storage

Store leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave for 1-2 minutes until warm, or in a preheated oven at 350 degrees F for about 10-15 minutes.
