This breakfast casserole uses frozen or homemade potato patties (hash browns) as the base, layered with eggs, cheese, and your choice of breakfast meat. It’s a hearty, crowd-pleasing dish that comes together in minutes and bakes into a golden, satisfying meal. The potato patties provide a crispy, savory crust that soaks up the egg mixture, making every bite flavorful and filling.
Ingredients
- 1 package (20 oz / 567 g) frozen shredded hash brown potato patties (about 8 patties), thawed and crumbled
- 1 lb (450 g) breakfast sausage or bacon, cooked and crumbled (optional, see variations)
- 2 cups (200 g) shredded cheddar cheese, divided
- 12 large eggs
- 1 cup (240 ml) milk (any kind)
- 1/2 cup (120 ml) sour cream
- 1 tsp (5 g) salt
- 1/2 tsp (2 g) black pepper
- 1/4 cup (25 g) chopped green onions (optional, for garnish)
Instructions
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch (23×33 cm) baking dish with butter or nonstick spray.
- In a large bowl, combine the crumbled potato patties with 1 cup (100 g) of the shredded cheddar cheese. Press the mixture evenly into the bottom of the prepared baking dish to form the crust.
- If using sausage or bacon, sprinkle it evenly over the potato crust.
- In the same bowl, whisk together the eggs, milk, sour cream, salt, and pepper until well combined and smooth.
- Pour the egg mixture over the potato and meat layer in the baking dish.
- Sprinkle the remaining 1 cup (100 g) of cheddar cheese over the top.
- Bake for 45–55 minutes, or until the center is set and a knife inserted near the middle comes out clean. The internal temperature should reach 160°F (71°C) as the safe minimum for egg dishes, according to USDA FSIS guidelines.
- Let the casserole rest for 5–10 minutes before slicing. Garnish with green onions if desired.
Tips
- Thaw the patties: If using frozen potato patties, thaw them in the refrigerator overnight or microwave them for a few minutes before crumbling. This prevents excess moisture and ensures a crispy crust.
- Don’t overbake: The casserole is done when the center is just set and no longer jiggly. Overbaking can make it dry and rubbery.
- Make it ahead: Assemble the casserole the night before, cover, and refrigerate. Add 10–15 minutes to the baking time when baking straight from the fridge.
- Substitutions: Use any cheese you like—pepper jack, Swiss, or a Mexican blend work well. Swap milk for half-and-half or heavy cream for a richer texture.
Serving Suggestions
Serve this casserole warm with a side of fresh fruit, toast, or a simple green salad. It’s perfect for brunch, holiday mornings, or meal prep for the week. A dollop of hot sauce or salsa on top adds a nice kick.
Variations
- Vegetarian: Omit the meat and add 1 cup (150 g) of sautéed bell peppers, onions, and mushrooms.
- Southwestern: Add 1 can (4 oz / 113 g) of diced green chiles and 1/2 tsp (1 g) of cumin to the egg mixture. Use pepper jack cheese.
- Ham and Swiss: Replace the sausage with 1 cup (150 g) of diced ham and use Swiss cheese instead of cheddar.
- Hash brown crust: Instead of patties, use 4 cups (600 g) of frozen shredded hash browns, thawed and squeezed dry. Press them into the dish and bake for 10 minutes before adding the egg mixture.
Storage and Reheating
Refrigerate leftovers in an airtight container for up to 4 days. To reheat, place a portion on a microwave-safe plate and microwave on high for 1–2 minutes, or reheat in a 350°F (175°C) oven for 10–15 minutes until warmed through. You can also freeze the baked casserole for up to 3 months; thaw overnight in the fridge before reheating.
Frequently Asked Questions
Can I use fresh potatoes instead of frozen patties? Yes, you can shred 4 medium potatoes (about 1.5 lb / 680 g), squeeze them dry, and press them into the dish. Par-bake the crust for 10 minutes before adding the egg mixture to ensure it crisps up.
Can I make this casserole without meat? Absolutely. Simply omit the sausage or bacon, and consider adding extra vegetables or a cup of cooked beans for protein.
Why is my casserole watery? Excess moisture often comes from undrained hash browns or vegetables. Make sure to thaw and squeeze the potato patties well, and if adding vegetables, sauté them first to remove extra liquid.
Can I use egg whites instead of whole eggs? Yes, you can substitute 8 egg whites for 4 of the whole eggs, but the casserole may be slightly less rich and set a bit faster. Keep an eye on the baking time.
How do I know when it’s fully cooked? The center should be set and a knife inserted near the middle should come out clean. For safety, use a food thermometer to check that the internal temperature reaches 160°F (71°C).
Can I freeze the unbaked casserole? Yes, assemble it in a disposable foil pan, cover tightly, and freeze for up to 3 months. Bake from frozen, adding about 20 minutes to the cooking time.
