Ingredients for Hash Brown Egg Casserole
- 8 precooked frozen hash brown patties (no thawing needed) – these form the hearty base of our casserole, providing that classic hash brown texture.
- 1 cup shredded sharp cheddar cheese – adds a rich, tangy flavor that melts beautifully.
- 1 cup shredded Monterey Jack cheese – brings a creamy texture and mild taste, balancing the sharpness of the cheddar.
- 1 & 1/2 cups diced leftover ham (about 3/4 pound) – this is where the protein comes in, giving the casserole a savory depth.
- 2 scallions, diced – for a fresh, oniony crunch that brightens up the dish.
- 9 large eggs – the binding agent that holds everything together, creating a fluffy texture.
- 1 cup whole milk – adds creaminess and moisture, making each bite deliciously rich.
- 1/2 teaspoon salt – enhances all the flavors, making them pop.
- 1/2 teaspoon dry ground mustard (optional) – a little kick that elevates the flavor profile.
- 1/4 teaspoon garlic powder – for that warm, aromatic touch that complements the other ingredients.
How to Make Hash Brown Egg Casserole
- Step 1: Preheat your oven to 350 degrees F. While it’s heating up, grease a 9×13 baking dish with a little butter or cooking spray to ensure nothing sticks.
- Step 2: Take those frozen hash brown patties and arrange them in a single layer at the bottom of the dish. You’ll want them to cover the entire base, creating a crispy foundation for our casserole.
- Step 3: Now, sprinkle the shredded sharp cheddar and Monterey Jack cheeses evenly over the hash browns, followed by the diced ham and scallions. The colors and textures are already looking so inviting!
- Step 4: In a large mixing bowl, whisk together the eggs, whole milk, salt, dry ground mustard, and garlic powder. The mixture should be smooth and creamy, and the aroma of garlic will start to fill the air.
- Step 5: Pour the egg mixture evenly over the cheese and ham layers. Make sure it seeps into all the nooks and crannies of the hash browns for maximum flavor.
- Step 6: Cover the dish with foil and pop it in the oven. Bake for 25 minutes. This will help the casserole set without browning too quickly.
- Step 7: After 25 minutes, carefully remove the foil and bake for another 20 minutes. You’ll know it’s ready when the edges are golden and a knife inserted in the center comes out clean.
- Step 8: Once it’s done, let the casserole cool for about 5-10 minutes. This resting time helps it firm up a bit, making it easier to cut into portions. Then, slice it up and serve warm!
