Ingredients You’ll Need
Gathering just a handful of familiar ingredients, this recipe relies on their perfect harmony to create a casserole bursting with flavor and texture. Each element, from the creamy eggs to the crisp-tender bell peppers, plays an essential role in delivering a balanced and satisfying dish.
- Frozen hash browns (30 oz): The crispy, golden base providing hearty texture and warmth to the casserole.
- Shredded cheddar cheese (1 cup): Adds rich creaminess and that irresistible cheesy pull in every bite.
- Chopped cooked ham or bacon (1 cup, optional): Brings a smoky, savory note that complements the eggs beautifully.
- Diced onion (1/2 cup): Infuses a subtle sweetness and depth of flavor when baked.
- Diced bell pepper (1/2 cup): Offers fresh color and a slight crunch to balance the softness.
- Large eggs (6): The binding ingredient that holds everything together with fluffy goodness.
- Milk (2 cups): Helps create a creamy, custard-like texture for the casserole.
- Garlic powder (1 teaspoon): Adds a gentle garlicky warmth.
- Salt (1 teaspoon): Enhances all the flavors to perfection.
- Black pepper (1/2 teaspoon): Provides just the right hint of spice.
- Paprika (1/4 teaspoon): Gives a subtle smoky undertone and a lovely color.
- Ground mustard (1/4 teaspoon): Adds a mildly tangy complexity that lifts the dish.
- Cooking spray or butter: Essential for greasing the dish to prevent sticking and create a crisp edge.
How to Make Hash Brown Egg Casserole Recipe
Step 1: Prep Your Oven and Dish
Start by preheating your oven to 350°F (175°C) to ensure it’s ready to bake your casserole to golden perfection. Lightly grease a 9×13-inch baking dish with cooking spray or butter, which will prevent any sticking and make cleanup a breeze.
Step 2: Combine the Hash Brown Mixture
In a large bowl, toss together the thawed hash browns, shredded cheddar cheese, chopped ham or bacon (if you’re using it), diced onion, and diced bell pepper. Mix thoroughly to ensure every bite will be packed with that delicious blend of flavors and textures.
Step 3: Layer the Base
Evenly spread the combined hash brown mixture across the bottom of your greased baking dish. Pressing it down gently will help it form a solid base for the egg mixture to soak into and bind everything together.
Step 4: Whisk the Egg Mixture
In a separate bowl, whisk together the eggs, milk, garlic powder, salt, black pepper, paprika, and ground mustard. Whisk until the mixture is completely smooth and well combined—this custard will give the casserole a rich, creamy texture.
Step 5: Pour and Settle
Carefully pour the egg mixture evenly over the hash brown layer. Use a spatula to gently press down the mixture, helping the eggs to settle in and fully cover the hash browns for even cooking and that beyond-satisfying custardy bite.
Step 6: Bake Until Golden and Set
Place the casserole in your preheated oven and bake for 45 to 55 minutes. You’ll know it’s done when the eggs have fully set, the top has a light golden-brown hue, and a clean knife inserted in the center comes out without any wet egg mixture.
Step 7: Cool and Serve
Once baked, let the casserole cool for 5 to 10 minutes. This rest allows it to firm up, making it easier to slice and ensuring each portion holds together beautifully when plated.
How to Serve Hash Brown Egg Casserole Recipe

Garnishes
Fresh herbs like chopped parsley or chives add a vibrant pop of color and fresh flavor that perfectly complements the richness of the casserole. For a little extra zing, a dollop of sour cream or a sprinkle of sliced green onions works wonders on top.
Side Dishes
This casserole pairs wonderfully with lighter sides to balance its heartiness. Consider serving it alongside a crisp green salad or fresh fruit salad to add brightness and refreshing contrast. Toasted crusty bread or warm biscuits are also fantastic for mopping up every cheesy, eggy bite.
Creative Ways to Present
For a festive brunch or gathering, cut the casserole into individual squares and serve on colorful plates with a garnish of cherry tomatoes or sliced avocado. You can also add a side bowl of your favorite hot sauce or salsa for guests who crave a little kick.
Make Ahead and Storage
Storing Leftovers
Wrap any leftover casserole tightly with plastic wrap or transfer it to an airtight container. Stored in the refrigerator, it will stay fresh for up to 3 days, making for easy breakfasts or snacks on busy mornings.
Freezing
This Hash Brown Egg Casserole Recipe freezes beautifully. To freeze, cool the casserole completely, then wrap it well with aluminum foil and place it in a freezer-safe container. It can be frozen for up to 2 months, perfect for prepping meals ahead of time.
Reheating
Reheat individual portions in the microwave for 1-2 minutes until warmed through. If reheating a whole casserole, cover it with foil and bake at 350°F (175°C) for about 20 minutes or until heated evenly.
FAQs
