Why You’ll Love This Recipe
Easy to Make Ahead. This breakfast casserole is ideal for prepping in advance. You can cook the sausage, onions and hashbrowns the night before, then layer and assemble the ingredients in your baking dish. The next morning, bake the casserole, and enjoy a filling breakfast in less than an hour.
Serves a Crowd. You can easily scale the recipe up or down for more or less servings. But if you’re like me, and you love leftovers, you’ll make a big pan just so that you can eat the leftovers all week.
Versatile. Use any kind of frozen hash browns, or even tater tots. Don’t like pork sausage? Use turkey sausage or cubed ham instead. Diced bell peppers or green chiles would add more flavor and color. Any kind of cheese will work, too!

- In a bowl, whisk together the eggs, milk, salt and pepper until smooth, then pour the egg mixture over the hash browns.If there doesn’t seem to be enough egg mixture, you can whisk 2 additional eggs with 1/4 cup milk to add to the casserole.
- Bake the casserole, uncovered, for about 35-45 minutes, until the casserole is puffed and set, and a knife inserted in the center comes out clean.
- Cool for 10 minutes, then cut and serve hot.

Frequently Asked Questions
Can this recipe be doubled?
Yes, you can double it and bake it in a 9×13 pan.
Do I have to cook the hash browns first, or can I bake the casserole with frozen hash browns?
Cooking the hash browns first cuts down on the time the casserole needs to bake. Also, the frozen hash browns may make the dish watery.
Can I assemble the casserole the night before and bake it in the morning?
Absolutely. Cook and prep the ingredients, layer and assemble the casserole, then cover the dish and refrigerate it until morning. In the morning, bake the casserole as instructed, adding a few more minutes of bake time.
Will this recipe work in individual ramekins or cocotte dishes?
Yes, of course! I’d probably divide it between 6-8 individual dishes, depending on their size and how large you want each serving to be.
