Here's a casserole you can make the night before the big holiday-morning spread, leaving you free to tie up other details. It's kind of like a fat Western omelet supercharged with crispy potato tots: hearty enough to be the main dish, fun for the kids and even gluten-free.
03Whisk together the eggs, milk, mustard, hot sauce, 1/2 teaspoon salt and 1/4 teaspoon ground black pepper in a large bowl.
04Sprinkle 1/2 cup of the Cheddar over the potatoes in the casserole dish. Layer the vegetable-beef mixture over the Cheddar. Pour the egg mixture into the dish and top with the remaining cup of Cheddar. (The casserole can be assembled up to this point and refrigerated overnight. Remove from the refrigerator 30 minutes before baking.)
05Preheat the oven to 350 degrees F. Top the casserole with the remaining potatoes (about 2 cups). Bake until the egg mixture is set and the top is lightly golden brown, 50 to 60 minutes. Let cool for 15 minutes before serving warm or at room temperature.
