Step‑by‑Step Instructions for Hash Brown Egg Casserole

Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While the oven warms, take a 9×13-inch baking dish and generously grease it with butter or cooking spray. This will ensure that your delicious Hash Brown Egg Casserole doesn’t stick. Set the dish aside as you prepare the filling.

Step 2: Cook the Meat
In a large skillet over medium heat, cook the breakfast sausage or crumbled bacon until it is nicely browned, which should take about 5–7 minutes. Stir occasionally to ensure even cooking. Once cooked, drain any excess grease, and set the meat aside on a paper towel-lined plate to cool slightly.

Step 3: Layer the Hash Browns
Spread half of the thawed hash browns evenly across the bottom of your prepared baking dish. This initial layer will form the hearty base of your Hash Brown Egg Casserole. Next, sprinkle the cooked sausage or bacon over the hash browns, followed by the diced onion and bell pepper to add delicious flavor and texture.

Step 4: Add Cheese Layers
Sprinkle 1½ cups of shredded cheddar cheese over the layered ingredients, ensuring an even distribution. The cheese will melt beautifully, integrating with the flavors of the Hash Brown Egg Casserole as it bakes. This layer serves as a scrumptious melty component, enhancing the overall dish.

Step 5: Whisk the Egg Mixture
In a large bowl, whisk together the 6 eggs, 1 cup of whole milk, garlic powder, salt, and black pepper until fully combined. The mixture should appear smooth and frothy. Pour this egg mixture evenly over the layered casserole, allowing it to seep into all the delicious ingredients below.

Step 6: Final Cheese Topping
Sprinkle the remaining ½ cup of cheddar cheese over the top of the casserole. Cover the baking dish with aluminum foil to help retain moisture while baking. This extra layer of cheese will create a beautiful, bubbly top once it’s done baking, adding to the final visual appeal of your dish.

Step 7: Initial Baking
Place the covered baking dish in the preheated oven and bake for 30 minutes. This will allow the flavors to meld beautifully while the eggs begin to set. Keep an eye on the casserole; the edges should start to bubble slightly during this initial baking phase.

Step 8: Final Uncovering and Baking
Carefully remove the foil from the casserole after 30 minutes. Return it to the oven and bake for an additional 15–20 minutes. You’ll know it’s done when the top is a golden brown and a knife inserted into the center comes out clean. This beautiful finish will signal that your Hash Brown Egg Casserole is ready to serve!

Step 9: Cool and Garnish
Once baked to perfection, remove the casserole from the oven and let it cool for about 5–10 minutes. This resting time allows the flavors to settle and makes slicing easier. If desired, garnish with chopped fresh parsley to add a touch of color before cutting into generous squares and serving warm.

Make Ahead Options

For busy home cooks, this Hash Brown Egg Casserole is an absolute lifesaver in meal prep! You can assemble the casserole up to 24 hours in advance; simply layer the ingredients as instructed, cover it tightly, and refrigerate. This method allows flavors to meld beautifully and saves precious time in the morning. If you prefer, you can also prepare individual components, such as cooking the sausage or chopping the veggies, 3 days ahead to further ease the prep process. When you’re ready to bake, just pop it in the oven directly from the fridge, adding an extra 5–10 minutes to the baking time for a delightful breakfast that’s just as delicious and comforting!
