5-Ingredient Hash Brown Breakfast Casserole

With only 5 main ingredients–potatoes, cheese, sausage (or bacon), eggs, and milk, this Hash Brown Breakfast Casserole is a cinch to throw together. You can even make it ahead of time and store in the fridge, or make this into a freezer meal using our instructions.

Reasons We Love This 5 Ingredient Breakfast Casserole

If a cheesy hash brown casserole had a baby with a traditional breakfast casserole (the kind with bread), you’d end up with this Breakfast Casserole with Hash Browns! It’s hearty, cheesy, and full of flavor from the meat and cheese. Bonus: This dish is gluten-free!

You can make it with your choice of meat: pork sausage, turkey sausage, or bacon. We like it with any of those choices. Amp up the flavor by adding in your favorite chopped and sautéed vegetables. Onions, bell peppers, mushrooms, spinach or kale would all be delicious additions. But, we decided to keep this recipe simple–5 main ingredients, in fact.

Ingredients for Breakfast Casserole with Hash Browns and Sausage

Here are the 5 main ingredients you’ll need to make this hearty and comforting casserole…

1. All-natural ground pork sausage or turkey sausage (Sub: uncured bacon, see Cooking Notes)
2. Refrigerated or frozen shredded hash browns (you’ll need to thaw them if they are frozen)
3. Shredded cheddar cheese (Dairy-free option: Omit the cheese.)
4. Eggs
5. Milk (Dairy-free option: Use unsweetened, plain almond milk or oat milk.)

You’ll also need a few pantry staples–salt, pepper, and a little cooking oil. You can eat the casserole “as is” or top it with items like hot sauce, salsa, ketchup, freshly chopped tomatoes and avocado.

How to Make Hash Brown Breakfast Casserole

After browning and draining the sausage, generously spray an 8×8 inch casserole dish with cooking spray. Then, add a layer of half of the shredded hash browns…

Next, add half the sausage…

Finally, sprinkle on half of the cheese in the dish, and repeat with the remaining hash browns, sausage, and cheese.

Now you’ll make the egg mixture. Whisk together the eggs, milk, salt, and pepper. Pour the egg mixture over the casserole.

Bake the casserole, uncovered, in a 350°F oven for 50-60 minutes or until done in the middle and bubbly around the edges.

How to Serve This Make-Ahead Breakfast Casserole

Serve a slice of casserole warm and, if desired, top with toppings like salsa, sour cream, chopped green onion, and diced avocado. Fresh fruit and berries make a great side dish, or serve it with one of our smoothies.
