Prep:

Preheat oven to 350°F and place rack in the center.

4. Add thawed hash browns to a greased 9×13-inch casserole dish. Drizzle with melted butter and toss to coat.
5. Sprinkle 1 cup of cheddar cheese over the hash browns. Add cooked sausage mixture.
6. Pour egg mixture over everything, then top with remaining cheese.

Bake:
7. Bake uncovered at 350°F for 50–55 minutes, or until edges are golden and center is nearly set.
8. Let rest for 10 minutes before slicing and serving.

Notes

Ham Option: Substitute with 2 (8 oz.) ham steaks, sautéed for 5 minutes and drained.

Hash Brown Tip: Fully thaw hash browns before use for best texture and even baking.

Storage: Refrigerate up to 3 days or freeze up to 3 months. Reheat in oven at 350°F for 20–25 minutes or microwave individual servings.
