How to Make Hash Brown Breakfast Casserole
Now that you have all your ingredients ready, let’s dive into the steps to create this mouthwatering Hash Brown Breakfast Casserole. Each step is simple, and I promise you’ll feel like a kitchen pro by the end of it!
Step 1: Preheat the Oven
First things first, preheat your oven to 350°F (175°C). This is crucial because a hot oven ensures even cooking. While it heats up, grab a 9×13-inch baking dish and grease it with cooking spray or butter. This will help your casserole come out easily and prevent sticking.
Step 2: Cook the Sausage and Vegetables
In a skillet over medium heat, add the crumbled breakfast sausage. Cook it until it’s browned and cooked through, about 5-7 minutes. The aroma will be irresistible! Once the sausage is ready, toss in the diced onion and bell pepper. Cook them until they’re softened, about 3-4 minutes. Don’t forget to drain any excess fat; we want a delicious casserole, not a greasy one!
Step 3: Combine Ingredients
In a large bowl, mix the cooked sausage and vegetable mixture with the frozen hash browns and half of the shredded cheddar cheese. Stir it all together until well combined. This is where the magic begins, as the flavors meld together beautifully!
“Make sure the hash browns are fully thawed and drained before mixing.”
Step 4: Prepare the Egg Mixture
In another bowl, whisk together the eggs, milk, garlic powder, salt, black pepper, and paprika. Make sure everything is fully combined. This egg mixture is what binds the casserole, giving it that fluffy texture we all love.
Step 5: Assemble the Casserole
Now it’s time to bring it all together! Pour the egg mixture over the hash brown and sausage mixture in the baking dish. Gently stir to combine everything. Finally, top it off with the remaining cheddar cheese. This will create a deliciously cheesy crust as it bakes!
Step 6: Bake the Casserole
Place your casserole in the preheated oven and bake for 45-50 minutes. Keep an eye on it! You’ll know it’s done when the top is golden brown and the casserole is set.
Step 7: Cool and Serve
Once it’s out of the oven, let the casserole cool for about 5-10 minutes. This step is important; it allows the flavors to settle and makes slicing easier. If you like, garnish with chopped green onions for a fresh touch. Now, slice it up and enjoy your delicious Hash Brown Breakfast Casserole!
Tips for Success
Use frozen hash browns for convenience; they save time and effort. Thaw hash browns before mixing for best results.
Don’t skip draining the sausage; it keeps the casserole from being greasy.
Let the casserole cool before slicing; it holds together better.
Experiment with different cheeses for unique flavors.
For a spicier kick, add diced jalapeños or use spicy sausage.
To make dairy-free, use plant-based cheese and non-dairy milk. For an egg substitute, try a vegan egg mix or flax eggs, though texture will vary.
If the top browns too quickly, cover loosely with foil during the final 10–15 minutes.
Equipment Needed
Baking dish: A 9×13-inch dish is ideal, but any similar-sized dish will work.
Skillet: A non-stick skillet makes cooking the sausage and veggies easier.
Mixing bowls: Use two bowls for mixing ingredients; one large and one medium.
Whisk: A whisk helps combine the egg mixture smoothly.
Spatula: A spatula is handy for mixing and serving the casserole.
Variations
Vegetarian Option: Swap the sausage for sautéed mushrooms or spinach for a delicious meatless version.
Cheese Lovers: Mix in different cheeses like mozzarella or feta for a unique flavor twist.
Southwestern Style: Add black beans, corn, and diced tomatoes for a zesty southwestern flair.
Low-Carb Version: Use cauliflower rice instead of hash browns for a lighter, low-carb alternative.
Herb Infusion: Incorporate fresh herbs like parsley or cilantro for an aromatic touch.
Serving Suggestions
Fresh Fruit: Serve with a side of mixed berries or sliced melons for a refreshing contrast.
Toast: Pair with buttered toast or bagels for a classic breakfast feel.
Coffee: A hot cup of coffee or a mimosa makes for a perfect morning beverage.
Presentation: Garnish with extra green onions or a sprinkle of paprika for a pop of color.
FAQs about Hash Brown Breakfast Casserole
Can I make Hash Brown Breakfast Casserole ahead of time?
Absolutely! You can prepare the casserole the night before and store it in the fridge. Just cover it tightly with plastic wrap. In the morning, pop it in the oven straight from the fridge, adding a few extra minutes to the baking time.
Can I freeze leftovers of the casserole?
Yes, this casserole freezes well! After it cools, slice it into portions and wrap them tightly in plastic wrap. Store in an airtight container or freezer bag. When you’re ready to enjoy, thaw in the fridge overnight and reheat in the oven.
What can I substitute for breakfast sausage?

Crumbled tofu can work in vegetarian versions but will have a different texture and flavor. Season well to enhance.

The casserole is done when the center is set and doesn’t jiggle when gently shaken.
