Ingredients
- 6 large eggs
- 1 cup shredded cheese (cheddar, mozzarella, or your favorite)
- 1 cup cooked breakfast sausage or ham, chopped
- 2 cups frozen hash browns or shredded potatoes
Instructions
- Preheat your oven to 375°F (190°C). Grease a 9×9-inch baking dish or similar-sized casserole dish with cooking spray or butter.
- In a large mixing bowl, beat the eggs until well combined. Season with a pinch of salt and pepper if desired.
- Add the shredded cheese, cooked sausage or ham, and frozen hash browns to the beaten eggs. Mix everything thoroughly to evenly distribute the ingredients.
- Pour the mixture into the prepared baking dish, spreading it out evenly.
- Place the casserole in the preheated oven and bake for 35-40 minutes, or until the eggs are set and the top is golden brown.
- Remove from oven and let it rest for 5 minutes before slicing and serving.
Tips
- Substitutions: You can swap the sausage for cooked bacon, ham, or even cooked vegetables like bell peppers or spinach for a vegetarian version.
- Frozen hash browns: Thaw slightly before mixing for easier incorporation, but it’s not strictly necessary.
- Cheese options: Feel free to experiment with different types of cheese such as pepper jack, Monterey Jack, or feta for varied flavors.
- Storage: Keep leftovers in an airtight container in the fridge for up to 3 days. Reheat in the microwave for 1-2 minutes or until hot.
Serving Suggestions
Serve this casserole hot, garnished with fresh herbs like parsley or chives if desired. It pairs well with a side of fresh fruit, a dollop of sour cream, or a simple green salad for a complete breakfast spread.
Variations
- Vegetarian: Omit the meat and add sautéed vegetables such as mushrooms, bell peppers, or spinach for a veggie-packed version.
- Spicy kick: Mix in some diced jalapeños or a dash of hot sauce into the egg mixture for added heat.
- Low-carb: Replace hash browns with cauliflower rice or omit potatoes altogether for a lower-carb option.
- Breakfast bowl: Serve the casserole in bowls topped with avocado slices or salsa for a different presentation.
Storage and Reheating
This casserole can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, microwave individual portions for 1-2 minutes, or until heated through. For larger portions, reheat in the oven at 350°F (175°C) for about 10-15 minutes. You can also freeze leftovers for up to a month; thaw overnight in the fridge and reheat as described.
Frequently Asked Questions
Can I prepare this casserole the night before?
Yes, you can assemble the casserole the night before, cover it tightly with plastic wrap, and refrigerate overnight. In the morning, simply bake it as directed. Just allow a few extra minutes for it to come to room temperature before baking if it’s very cold.
What if I don’t have frozen hash browns?
If you don’t have hash browns, you can substitute with grated raw potatoes or cooked and chopped fresh potatoes. Alternatively, shredded zucchini or cauliflower rice can be used for a lower-carb variation, but adjust cooking times accordingly.
Can I make this casserole gluten-free?
Absolutely. This recipe is naturally gluten-free as long as your sausage and cheese do not contain gluten additives. Always check labels to ensure all ingredients are gluten-free.
How do I know when the casserole is done?
The casserole is ready when the eggs are fully set and the top is golden brown. You can insert a toothpick or knife into the center; if it comes out clean or with just a few moist crumbs, it’s done. The baking time is approximately 35-40 minutes at 375°F.
Can I add other ingredients later?
It’s best to add ingredients like fresh herbs or vegetables after baking to preserve their flavor and texture. Adding wet ingredients before baking may make the casserole soggy or affect the cooking time.
