Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

8 large eggs
1 cup milk
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon dried thyme
Salt and pepper, to taste
4 cups frozen hash browns, thawed
1 cup cooked sausage, crumbled
1 cup shredded sharp cheddar cheese
1/2 cup green bell pepper, diced
1/2 cup red bell pepper, diced
1/4 cup green onions, sliced

Directions

I start by preheating the oven to 350°F (175°C) and greasing a 9×13-inch baking dish with cooking spray or olive oil.

In a large bowl, I whisk the eggs, milk, garlic powder, onion powder, dried thyme, salt, and pepper until everything is well combined.

I spread the thawed hash browns evenly across the bottom of the baking dish. Then, I layer the crumbled cooked sausage on top, followed by the diced green and red bell peppers.

I carefully pour the egg mixture over the ingredients in the dish, making sure it’s evenly distributed.

I top the casserole with shredded sharp cheddar cheese and sprinkle sliced green onions for a fresh finish.

The dish goes into the preheated oven and bakes for 40–45 minutes, or until the eggs are fully set and the top is golden brown.

After baking, I let it cool for 5–10 minutes before slicing into squares. This makes it easier to serve and helps the casserole hold its shape.

Variations

Vegetarian: I like to skip the sausage and add sautéed mushrooms, spinach, or zucchini.
Vegan: I replace the eggs with a silken tofu blend and use nutritional yeast for a cheesy flavor. I also use plant-based milk and vegan sausage or extra veggies.
Cheese Swaps: Mozzarella gives a creamy stretch, feta adds a salty punch, and pepper jack offers some heat. Mixing cheeses is a fun way to personalize the dish.
Seasonal Additions: In spring, I add asparagus. For summer, I love zucchini or tomatoes. Fall works well with kale or butternut squash. Winter calls for hearty veggies like sweet potatoes.

storage/reheating

Refrigeration: Once the casserole cools, I slice it into portions and store them in an airtight container. It stays fresh in the fridge for up to 4 days.

Freezing: I let the casserole cool, slice it, wrap each piece tightly in plastic wrap, and place them in a freezer-safe bag. It keeps well for up to 3 months. I thaw it overnight in the fridge before reheating.

Reheating: For the best texture, I reheat in the oven at 350°F (175°C) for about 20 minutes, covered with foil. For quick reheating, I microwave individual slices for 1–2 minutes, checking for doneness.

FAQs

Can I make this casserole the night before?

Absolutely. I often prepare the entire casserole, cover it with plastic wrap, and keep it in the fridge overnight. The next morning, I just bake it fresh. It saves time and tastes just as good.

What sides go well with sausage egg casserole?

I like to serve it with fresh fruit like melon or berries. A simple green salad works well, or even toast, bagels, or roasted potatoes. For more flavor, I sometimes add hot sauce or a spoonful of salsa.

How do I know the casserole is fully cooked?

I look for a golden brown top and gently shake the dish. If the center jiggles, it needs more time. I also insert a knife in the middle — if it comes out clean, it’s ready.

Can I use fresh potatoes instead of frozen hash browns?

Yes, I can grate fresh potatoes and squeeze out the excess moisture before layering. This makes the bottom crispy and adds a homemade touch.

What if my casserole is cooking too fast?

If I notice the top browning too quickly, I loosely cover it with foil and lower the temperature to 325°F (160°C). This helps it cook evenly without burning.

Conclusion

This easy sausage egg casserole has become one of my go-to breakfast dishes for busy mornings and weekend brunches. It’s filling, flavorful, and easy to make ahead. With its versatility, I can customize it to suit any taste or season. Whether I’m feeding a crowd or meal prepping for the week, this recipe never disappoints.
