Ingredients

Scale
  • 20 ounces shredded hashbrowns (thawed)
  • 1 pound ground lamb sausage (cooked, crumbled, and drained)
  • ¼ cup finely diced onion
  • ½ red bell pepper (diced)
  • ½ green bell pepper (diced)
  • 2 cups shredded cheddar cheese (divided)
  • 8 eggs
  • 12 ounces evaporated milk (or 1⅓ cups milk)
  • ½ teaspoon Italian seasoning (optional)
  • ½ teaspoon kosher salt (or to taste)
  • ¼ teaspoon black pepper

Instructions

Step 1: Prepare the Baking Dish
Start by greasing a 9×13-inch baking dish with cooking spray. This will prevent the casserole from sticking and make cleanup much easier.

Step 2: Cook the Sausage
In a large skillet over medium-high heat, cook the ground lamb sausage until it’s browned and no longer pink. Use a spoon or spatula to break it up into crumbles. Drain any excess grease and set the sausage aside to cool slightly.

Step 3: Assemble the Casserole Layers

  • Spread the thawed hashbrowns evenly across the bottom of the prepared baking dish.
  • Layer the cooked sausage over the hashbrowns, followed by the diced onions and bell peppers.
  • Sprinkle 1½ cups of shredded cheddar cheese on top of the vegetable layer.

Step 4: Prepare the Egg Mixture
In a large mixing bowl, whisk together the eggs, evaporated milk, Italian seasoning (if using), kosher salt, and black pepper. Make sure the mixture is well combined for even cooking.

Step 5: Pour and Top
Pour the egg mixture evenly over the layers in the casserole dish. Use a spoon to ensure the egg mixture spreads evenly across the dish. Sprinkle the remaining ½ cup of cheese on top.

Step 6: Bake or Refrigerate

  • If Baking Immediately: Preheat your oven to 350°F (175°C). Bake the casserole uncovered for 55–65 minutes, or until the center is set and a knife inserted into the middle comes out clean. The top should be golden brown and bubbly.
  • If Preparing Ahead: Cover the assembled casserole with foil and refrigerate for up to 48 hours. When ready to bake, let it sit at room temperature for 30 minutes before placing it in the oven. You may need to add 10–15 minutes to the baking time.

Step 7: Rest and Serve
Once baked, let the casserole rest for about 10 minutes. This helps it set, making it easier to slice and serve. Garnish with fresh herbs if desired, and serve warm.

Notes

  • Customizable Protein Options: Substitute lamb sausage with turkey sausage, beef sausage, or even plant-based sausage for a vegetarian option.
  • Storage: Store leftovers in an airtight container in the refrigerator for up to 3–4 days. Reheat in the microwave or oven until warmed through.
