Ingredients
This recipe makes 8 generous servings.
For the Casserole Base:
- 30 ounces (about 1 bag) frozen shredded hashbrowns, thawed
- 1 tablespoon olive oil
- 1 pound breakfast sausage (pork, turkey, or plant-based)
- 1 medium yellow onion, chopped
- 1 red bell pepper, chopped
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon garlic powder
- ½ teaspoon onion powder
For the Egg Mixture:
- 8 large eggs
- 1 cup milk (any kind works: whole, 2%, skim, or non-dairy)
- ½ teaspoon salt
- ¼ teaspoon black pepper
For the Cheese Topping:
- 2 cups shredded cheddar cheese (or a cheddar-jack blend)
Step-by-Step Instructions
-
Step 1: Prepare Your Oven and Baking Dish
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish with cooking spray or butter. This will help prevent sticking and make cleanup easier.
Small tip: Make sure your hashbrowns are fully thawed before you start. You can thaw them in the fridge overnight or spread them on a baking sheet at room temperature for about 30 minutes.
-
Step 2: Cook the Sausage and Vegetables
Heat the olive oil in a large skillet over medium-high heat. Add the breakfast sausage and cook, breaking it up with a spoon, until it’s fully browned. Drain any excess grease from the skillet.
Add the chopped onion and red bell pepper to the skillet with the cooked sausage. Cook for about 5-7 minutes, until the vegetables are softened. Stir in the salt, pepper, garlic powder, and onion powder. Remove from heat.
-
Step 3: Layer the Hashbrowns
Press the thawed hashbrowns evenly into the bottom of your prepared 9×13 inch baking dish. Make sure they form a nice, compact layer. This will be the delicious foundation of your casserole.
-
Step 4: Add the Sausage Mixture
Spoon the cooked sausage and vegetable mixture evenly over the layer of hashbrowns. Spread it out so every bite gets some of that savory goodness. Don’t worry if it’s not perfectly flat.
-
Step 5: Whisk the Egg Mixture
In a large bowl, whisk together the eggs, milk, ½ teaspoon salt, and ¼ teaspoon black pepper until well combined and slightly frothy. Whisking ensures a light and even texture for your eggs.
-
Step 6: Pour and Top with Cheese
Carefully pour the egg mixture evenly over the hashbrowns and sausage in the baking dish. Make sure the egg mixture reaches all the way to the edges. Finally, sprinkle the shredded cheddar cheese generously over the top of the casserole.
Small tip: For extra flavor, you can add a pinch of paprika or a dash of hot sauce to the egg mixture.
-
Step 7: Bake to Golden Perfection
Place the baking dish in the preheated oven. Bake for 45-50 minutes, or until the eggs are set in the center and the cheese is melted and bubbly and golden brown. A knife inserted into the center should come out clean.
Small tip: If the cheese starts to brown too quickly, you can loosely cover the casserole with aluminum foil for the last 10-15 minutes of baking.
-
Step 8: Rest and Serve
Once baked, remove the casserole from the oven and let it rest for 5-10 minutes before slicing and serving. This resting time allows the casserole to set further and makes for cleaner slices. Enjoy your delicious breakfast!
Tips & Variations
- Gluten-Free Option: This recipe is naturally gluten-free, but always double-check the labels on your frozen hashbrowns and breakfast sausage to ensure no hidden gluten ingredients.
- Vegetarian or Vegan Option: For a vegetarian version, simply swap the breakfast sausage for a plant-based sausage crumble or sautéed mushrooms. For a vegan option, use plant-based sausage, a whisked “egg” substitute (like Just Egg), dairy-free milk, and dairy-free shredded cheese.
- Add More Vegetables or Protein: Feel free to add more veggies like chopped spinach (sautéed and squeezed dry), diced zucchini, or sliced mushrooms to the sausage mixture. For extra protein, you can add cooked, diced ham or crumbled bacon along with the sausage.
- Spicy Kick: If you love a little heat, add a diced jalapeño (remove seeds for less heat) to the sausage and veggie mixture. You can also sprinkle in a pinch of red pepper flakes with the seasonings or serve with your favorite hot sauce.
- Creamy Texture: For an extra creamy casserole, mix a can of condensed cream of mushroom or chicken soup (or a dairy-free alternative) into the egg mixture before pouring it over the hashbrowns.

Health Benefits
This Hashbrown Breakfast Casserole isn’t just delicious; it also packs some great nutritional benefits thanks to its wholesome ingredients.
Eggs are a fantastic source of high-quality protein, essential for muscle repair and growth. They also provide important B vitamins, which are crucial for energy production, and choline, a nutrient vital for brain health and metabolism.
The vegetables like onion and bell pepper contribute a good dose of vitamins and fiber. Bell peppers are especially rich in Vitamin C, an antioxidant that supports your immune system. Onions offer antioxidants and compounds that may help reduce inflammation.
Hashbrowns, made from potatoes, are often overlooked but are a good source of complex carbohydrates, providing sustained energy to start your day. They also contain potassium, important for blood pressure regulation, and more Vitamin C.
While cheese should be enjoyed in moderation, it provides calcium for strong bones and additional protein. When combined, these ingredients create a balanced meal that keeps you feeling full and energized throughout your morning.
Serving Suggestions
- Serve warm with a side of fresh fruit salad for a light, refreshing contrast.
- Drizzle with your favorite hot sauce or a dollop of sour cream or Greek yogurt for extra flavor and creaminess.
- Enjoy it as the main dish for a hearty breakfast or brunch. It also makes a fantastic side dish for a larger holiday meal.

Storage Tips
Leftover Hashbrown Breakfast Casserole can be stored in an airtight container in the refrigerator for up to 3-4 days. It also freezes beautifully!

To reheat, thaw overnight in the fridge (if frozen) and warm in the oven at 350°F (175°C) until heated through, or microwave individual portions until hot.
