Ingredients You’ll Need

Core Ingredients for the Base

• 1 lb ground breakfast sausage (or turkey/chicken sausage)
• 6 large eggs
• 2 cups milk
• 1 teaspoon salt
• ½ teaspoon black pepper
• 7.5 oz frozen hash browns (half a 15 oz bag)
• 2 cups shredded cheddar cheese

Notes on Sausage, Cheese, and Hash Browns

Use any sausage you love pork adds richness, while turkey keeps it lighter. Shred your own cheese for the best melt. Thaw and dry hash browns first to avoid sogginess.

How to Make Homemade Breakfast Casserole (Step-by-Step)

Step 1: Preheat the Oven and Prep the Baking Dish

Preheat oven to 350°F (175°C). Grease a 9×13-inch dish with butter or spray to keep the edges golden and prevent sticking.

Step 2: Brown and Drain the Sausage Properly

Cook sausage in a skillet over medium heat until browned and crumbly. Drain the grease well to keep the casserole light and balanced.

Step 3: Whisk the Egg Mixture for the Best Texture

In a large bowl, whisk together eggs and milk until smooth. Add salt and pepper. Whisking well ensures even texture and fluffiness when baked.

Step 4: Layer Hash Browns, Sausage, and Cheese Evenly

Spread hash browns in the baking dish, followed by sausage and cheese. Mixing lightly helps distribute ingredients evenly.

Step 5: Pour the Egg Mixture Over the Dish

Slowly pour your egg mix over everything, letting it seep into every layer. This keeps each bite rich and consistent.

Step 6: Bake Covered, Then Uncovered Until Set

Cover with foil and bake for 45 minutes. Remove the foil, then bake another 10–15 minutes until hot, bubbly, and golden.

Step 7: Let the Casserole Rest Before Slicing

Let it cool for about 20 minutes. This short wait makes slicing neater and helps the flavors settle beautifully.

Tips for Best Results

Thawing Hash Browns to Avoid Excess Moisture

Always thaw and squeeze out extra liquid before layering. Too much moisture prevents a crisp texture.

Why Resting Time Improves Slices

Allowing the casserole to rest helps the eggs firm up, so you get tidy, flavorful squares instead of runny edges.

Choosing the Right Milk for Creaminess

Whole milk or half-and-half gives the richest texture. You can use any milk, but higher fat equals smoother results.

Flavor Boosters and Seasoning Ideas

Try a pinch of garlic powder, chopped green onions, or diced bell peppers for extra flavor. A sprinkle of paprika on top adds a warm color and aroma.

Easy Substitutions and Variations

Protein Swaps Like Bacon, Ham, or Vegetarian Options

Swap sausage for bacon, diced ham, or crumbled tofu. Vegetarian sausage also works well.

Cheese Options From Mild to Bold

Cheddar brings comfort, while pepper jack adds spice. Try Monterey Jack or Swiss for a gentler, creamy flavor.

Hash Brown Alternatives and Mix-Ins

Use cubed potatoes, sweet potatoes, or even cauliflower rice for a twist. Add spinach or mushrooms for an earthy balance.

How to Freeze and Thaw Properly

Freeze individual portions wrapped in foil for up to 3 months. Thaw overnight in the fridge before reheating.
