A hearty and easy breakfast casserole combining crispy hash browns, savory sausage, melted cheese, and fluffy eggs baked to golden perfection. Perfect for busy mornings, holiday brunches, or any occasion that calls for comfort food.

Ingredients

Scale
  • 4 cups (about 400g) frozen shredded hash browns, plain and unseasoned
  • 1 pound (450g) breakfast sausage, cooked and crumbled (can substitute bacon or ham)
  • 2 cups (200g) shredded sharp cheddar cheese (optional mix with mozzarella)
  • 8 large eggs, room temperature
  • 1 cup (240ml) whole milk or 2% milk
  • 1 small onion, finely chopped
  • 1 teaspoon garlic powder
  • Salt and black pepper, to taste
  • 1/2 teaspoon smoked paprika (optional)
  • 1 tablespoon butter, for greasing the baking dish

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish with butter.
  2. In a skillet over medium heat, crumble and cook the sausage until browned and cooked through, about 7-10 minutes. Drain excess fat if needed. Add the finely chopped onion during the last 2 minutes to soften.
  3. In a large bowl, whisk together the eggs, milk, garlic powder, smoked paprika (if using), salt, and black pepper until well combined and slightly frothy.
  4. Spread the frozen shredded hash browns evenly in the bottom of the greased baking dish. Do not thaw.
  5. Evenly scatter the cooked sausage and softened onion mixture over the hash browns.
  6. Sprinkle the shredded cheddar cheese evenly over the sausage layer.
  7. Slowly pour the egg and milk mixture over everything, ensuring it seeps through the layers.
  8. Bake uncovered for 45-50 minutes until the top is golden brown, eggs are set with no jiggle, and edges of hash browns are crispy. If top browns too fast, cover loosely with foil for the last 10 minutes.
  9. Let the casserole rest for about 10 minutes before slicing and serving.

Notes

Use frozen hash browns for best crispiness; do not thaw before baking. Whisk eggs and milk until frothy for a fluffier texture. If top browns too quickly, cover with foil. Can assemble the night before and refrigerate; add 10 minutes to baking time if baking from cold. For extra cheesy crust, add more cheese halfway through baking. Variations include vegetarian (swap sausage for mushrooms and veggies), low-carb (use cauliflower rice), spicy (add jalapeños and pepper jack cheese), and dairy-free options.
