Sausage Hash Brown Casserole Recipe

Ingredients

1 lb breakfast sausage
24 oz frozen shredded hash brown potatoes (approximately 8 cups)
2 cups shredded cheddar cheese
12 large eggs
1 cup milk (or a plant-based alternative like almond or oat milk if preferred)
1 tsp salt
1/2 tsp ground black pepper

Instructions

Set your oven to 350°F (175°C). Grease a 9×13-inch baking dish lightly with cooking spray or oil.
Heat a large skillet over medium heat. Add the sausage and break it apart using a wooden spoon. Cook for about 7 minutes, stirring occasionally, until it browns completely. Remove from heat and drain any excess fat.
In a large mixing bowl, combine the cooked sausage, frozen hash browns, and shredded cheddar cheese. Mix until everything is evenly distributed. Transfer this mixture to the greased baking dish.
Using the same bowl (to save on cleanup), whisk together the eggs, milk, salt, and pepper until fully blended.
Pour the egg mixture evenly over the hash brown and sausage mixture in the baking dish. Use the back of a wooden spoon to gently press everything down to ensure it’s packed evenly.
Place the dish in the preheated oven and bake for about 1 hour. When done, the center should no longer jiggle, and the edges should have a golden brown color.
Allow the casserole to cool for 5 minutes before slicing it into portions. Serve warm.

Tips For Making Sausage Hash Brown Breakfast Casserole

A little planning and preparation can make your casserole even tastier and easier to create. Here are some useful tips to ensure your dish turns out perfectly every time:

Cook the sausage thoroughly: Make sure to brown the sausage completely and drain any excess fat. This prevents the casserole from becoming greasy.
Thaw frozen hash browns: If you’re using frozen hash browns, thaw them beforehand and pat them dry with a paper towel to remove any extra moisture. This helps achieve a better texture.
Use fresh ingredients: Freshly grated cheese melts better than pre-shredded cheese, which often contains anti-caking agents.
Season to taste: Feel free to adjust the salt and pepper based on your preferences, but remember the sausage and cheese already have salt.
Don’t skip greasing the pan: Lightly grease the baking dish to prevent sticking and make cleanup easier.

Variations For Sausage Hash Brown Breakfast Casserole

If you love experimenting with flavors, this casserole is a great base to customize. Here are some ideas to switch things up:

Add vegetables: Toss in diced bell peppers, onions, spinach, or mushrooms for extra flavor and nutrients.
Try different cheeses: Swap cheddar for mozzarella, pepper jack, or a mix of your favorites to change the flavor.
Use turkey or chicken sausage: For a lighter version, substitute pork sausage with turkey or chicken sausage.
Spice it up: Add chopped jalapeños, a dash of hot sauce, or a sprinkle of smoked paprika for a bit of heat.
Go dairy-free: Use plant-based cheese and milk to make it dairy-free without losing the creaminess.
Make it meatless: Skip the sausage and load up on veggies for a vegetarian version.

Assemble and Refrigerate: Prepare the casserole up to the point of baking.

When ready to bake, simply remove the cover and bake as usual, adding a few extra minutes to the cooking time if needed.
