 Ingredients

 For the Casserole Base:

• 1 (30 oz / 850 g) bag frozen hash brown potatoes, thawed

• 1 medium onion, finely chopped

• 1 medium bell pepper (any color), diced

• 2 cloves garlic, minced

• 2 cups shredded cheddar cheese (sharp or mild)

• 1 cup shredded mozzarella cheese

• 8 large eggs

• 1 ½ cups whole milk (or 1 cup milk + ½ cup heavy cream for extra richness)

• ½ tsp salt

• ½ tsp black pepper

• ½ tsp paprika

• ¼ tsp garlic powder

• ¼ tsp onion powder

• 2 tbsp butter or olive oil for greasing and cooking

 Optional Add-ins and Toppings:

• ¼ cup chopped green onions (for garnish)

• ½ tsp red pepper flakes (for a little heat)

• Hot sauce for serving

 Step-by-Step Instructions

Step 1: Preheat and Prep

Preheat your oven to 375°F (190°C).
Grease a 9×13-inch baking dish generously with butter or nonstick cooking spray.

If your hashbrowns are frozen, make sure they’re thawed and patted dry with paper towels to remove excess moisture — this helps your casserole bake evenly and stay fluffy, not soggy.

Step 2: Cook the Sausage

1. Heat a large skillet over medium-high heat.

2. Add the breakfast sausage, breaking it apart with a spatula.

3. Cook until browned and no longer pink (about 6–8 minutes).

4. Once cooked, drain any excess grease.

5. Set the cooked sausage aside in a bowl.

Tip: Want an extra burst of flavor? Use a mix of mild and spicy sausage or add a sprinkle of fennel seeds to mimic Italian sausage.

Step 3: Sauté the Vegetables

1. In the same skillet, melt 1 tablespoon of butter.

2. Add the onion and bell pepper, cooking until softened (about 4–5 minutes).

3. Add garlic and cook for another 30 seconds until fragrant.

4. Remove from heat and combine with the cooked sausage.

Pro Tip: You can add mushrooms, spinach, or even diced jalapeños here for extra flavor and texture.

Step 4: Mix the Hashbrowns

In a large mixing bowl, combine:

• Thawed hashbrowns,

• ½ of the shredded cheddar,

• ½ of the mozzarella, and

• A pinch of salt and pepper.

Toss everything until evenly coated.

Step 5: Layer the Casserole

Now comes the fun part — layering all that deliciousness!

1. Spread the hashbrown mixture evenly on the bottom of the greased baking dish.

2. Evenly distribute the cooked sausage and vegetable mixture on top.

3. Sprinkle with the remaining cheddar and mozzarella cheese.

Optional: For an even creamier texture, dot small spoonfuls of sour cream or cream cheese across the top before pouring in the eggs.

Step 6: Whisk the Egg Mixture

In a medium bowl, whisk together:

• 8 eggs,

• Milk (or milk + cream),

• Salt, pepper, paprika, garlic powder, and onion powder.

Pour this egg mixture evenly over the layered casserole. Use a spatula to gently press everything down so the eggs soak through the layers.

Step 7: Bake Until Golden and Bubbly

Place the dish in the preheated oven and bake for 40–45 minutes, or until the casserole is set in the center and golden brown on top.

To check for doneness:

• Insert a knife into the center — it should come out clean.

• The top should be lightly puffed and golden.

If the top browns too quickly, loosely cover with foil halfway through.

Step 8: Cool and Serve

Once baked, remove the casserole from the oven and allow it to rest for 10–15 minutes. This lets the layers firm up, making it easier to slice.

Garnish with chopped green onions, a drizzle of hot sauce, or even a dollop of sour cream for extra flavor.

 Serving Suggestions

This Sausage Egg Hashbrown Casserole is incredibly versatile. Here are a few pairing ideas:

• Serve with fresh fruit salad or orange juice for a classic breakfast spread.

• Pair with buttered toast, biscuits, or English muffins.

• Add a side of crispy bacon or smoked ham for meat lovers.

 Tips & Tricks

 1. Use the Right Hashbrowns

Both shredded and diced hashbrowns work beautifully. For a crispier base, lightly pan-fry them before layering in the casserole.

In the morning, bake as directed — just add an extra 5–10 minutes to the cooking time.

 3. Freezer Friendly

This casserole freezes beautifully.

• Assemble it completely, wrap it in foil and plastic wrap, and freeze for up to 3 months.

• To bake from frozen, thaw overnight in the fridge, then bake as usual.

 4. Cheese Options

Switch up your flavors with:

• Pepper Jack for spice

• Colby Jack for creaminess

• Swiss or Gruyère for a nutty depth

 5. Add More Protein

Mix in bacon, ham, or even chopped chicken sausage for extra heartiness.

 6. Add Veggies for Nutrition

Include spinach, broccoli, mushrooms, or tomatoes for a colorful and wholesome version.
