1 pound sliced bacon, diced
1 medium sweet onion, chopped
6 large eggs, lightly beaten
4 cups frozen shredded hash brown potatoes, thawed
2 cups shredded cheddar cheese
1 ½ cups 4% cottage cheese
1 ¼ cups shredded Swiss cheese
Best if assembled the night before and refrigerated overnight.
Preheat oven to 350°. In a large skillet, cook bacon and onion over medium heat until bacon is crisp; drain. In a large bowl, combine remaining ingredients; stir in bacon mixture. Transfer to a greased 13×9-in. baking dish.
Bake, uncovered, until a knife inserted in the center comes out clean, 35-40 minutes. Let stand 10 minutes before cutting.
