Ingredients You’ll Need

Before you start, gather all the ingredients. This will make the cooking process much smoother and more enjoyable.

* **Frozen Hash Browns:** 30 ounces, thawed. Thawing is crucial for even cooking and preventing a watery casserole. You can use shredded or diced hash browns, depending on your preference.
* **Breakfast Sausage:** 1 pound, cooked and crumbled. You can use regular or spicy sausage, or substitute with bacon, ham, or chorizo. For a vegetarian option, use plant-based sausage or cooked vegetables like mushrooms and bell peppers.
* **Butter:** 1/2 cup (1 stick), melted. The butter is used to create the roux for the cheese sauce and adds richness to the casserole.
* **All-Purpose Flour:** 1/2 cup. This is the thickening agent for the cheese sauce.
* **Milk:** 3 cups. Whole milk is recommended for a richer sauce, but you can use 2% or skim milk if you prefer. Almond milk or soy milk can be used for a dairy-free version.
* **Shredded Cheddar Cheese:** 2 cups. Sharp cheddar provides a nice tangy flavor, but you can use any cheese you like, such as Colby Jack, Monterey Jack, or a blend of cheeses.
* **Sour Cream:** 1 cup. Sour cream adds a creamy tang to the casserole. Greek yogurt can be used as a substitute.
* **Onion:** 1/2 cup, chopped. Adds a savory flavor to the casserole.
* **Garlic:** 2 cloves, minced. Enhances the flavor of the cheese sauce.
* **Salt and Pepper:** To taste. Season generously to bring out the flavors of the other ingredients.
* **Optional Toppings:** Crushed cornflakes, crispy fried onions, or extra shredded cheese.

Equipment Needed

* **Large Skillet:** For cooking the sausage and making the cheese sauce.
* **9×13 inch Baking Dish:** For baking the casserole.
* **Mixing Bowls:** For combining the ingredients.
* **Whisk:** For making the cheese sauce.
* **Measuring Cups and Spoons:** For accurate ingredient measurements.

Step-by-Step Instructions

Now, let’s get to the fun part – making the casserole! Follow these detailed instructions for a perfect result every time.

**Step 1: Prepare the Sausage**

* If using sausage, cook it in a large skillet over medium heat until fully cooked and crumbled. Drain off any excess grease.
* Set the cooked sausage aside.

**Step 2: Make the Cheese Sauce**

* In the same skillet, melt the butter over medium heat.
* Add the chopped onion and minced garlic and sauté until softened, about 3-5 minutes.
* Whisk in the flour and cook for 1-2 minutes, stirring constantly, to create a roux.
* Gradually whisk in the milk, making sure to break up any lumps. Continue whisking until the sauce is smooth and begins to thicken, about 5-7 minutes.
* Remove the skillet from the heat.
* Stir in the shredded cheddar cheese and sour cream until the cheese is melted and the sauce is smooth and creamy.
* Season with salt and pepper to taste.

**Step 3: Assemble the Casserole**

* In a large mixing bowl, combine the thawed hash browns, cooked sausage, and cheese sauce.
* Mix well to ensure that all the hash browns are coated with the sauce.
* Pour the mixture into a greased 9×13 inch baking dish.
* Spread the mixture evenly in the dish.

**Step 4: Add Toppings (Optional)**

* If desired, sprinkle the casserole with crushed cornflakes, crispy fried onions, or extra shredded cheese.

**Step 5: Bake (or Refrigerate)**

* **To Bake Immediately:** Preheat your oven to 350°F (175°C).
* Bake the casserole for 30-40 minutes, or until it is golden brown and bubbly.
* **To Make Ahead:** Cover the assembled casserole with plastic wrap and refrigerate for up to 24-48 hours. If refrigerating, you may need to add 10-15 minutes to the baking time.
* When ready to bake, preheat your oven to 350°F (175°C).
* Bake the casserole, uncovered, for 40-50 minutes, or until it is golden brown and bubbly. If the topping starts to brown too quickly, you can cover the casserole with aluminum foil during the last 15-20 minutes of baking.

**Step 6: Let it Rest and Serve**

* Once the casserole is done baking, remove it from the oven and let it rest for 5-10 minutes before serving.
* This allows the casserole to set slightly and prevents it from being too runny.
* Serve warm and enjoy!

Tips for the Perfect Hash Brown Potato Casserole

* **Thaw the Hash Browns:** This is the most crucial step! Thawing the hash browns ensures that they cook evenly and prevents the casserole from being watery. You can thaw them in the refrigerator overnight or use the defrost setting on your microwave.
* **Don’t Overcook the Sausage:** Cook the sausage until it’s just cooked through. Overcooked sausage can be dry and tough.
* **Adjust the Cheese Sauce Consistency:** If the cheese sauce is too thick, add a little more milk until it reaches your desired consistency. If it’s too thin, cook it for a few more minutes, stirring constantly, until it thickens.
* **Grease the Baking Dish:** This will prevent the casserole from sticking to the dish and make it easier to clean.
* **Don’t Overbake:** Overbaking can dry out the casserole. Bake until it’s golden brown and bubbly, and the cheese is melted and gooey.
* **Use a Meat Thermometer:** If you’re unsure whether the casserole is fully heated through, use a meat thermometer to check the internal temperature. It should reach 165°F (74°C).
* **Customize with Your Favorite Ingredients:** Feel free to add your own twist to the recipe. Experiment with different cheeses, vegetables, or meats to create a casserole that’s perfect for your taste.

Variations and Add-Ins

One of the best things about this recipe is its versatility. Here are a few ideas to get you started:

* **Vegetarian:** Omit the sausage and add sautéed mushrooms, bell peppers, onions, and spinach.
* **Spicy:** Use spicy sausage or add a pinch of cayenne pepper to the cheese sauce.
* **Bacon:** Substitute the sausage with cooked and crumbled bacon.
* **Ham:** Use diced ham instead of sausage.
* **Chorizo:** Add cooked and crumbled chorizo for a Mexican-inspired flavor.
* **Jalapeños:** Add diced jalapeños to the cheese sauce for a spicy kick.
* **Different Cheeses:** Experiment with different cheeses, such as Colby Jack, Monterey Jack, pepper jack, or a blend of cheeses.
* **Green Onions:** Sprinkle chopped green onions on top of the casserole before baking or serving.
* **Diced Tomatoes:** Add diced tomatoes to the hash brown mixture for added flavor and texture.
* **Corn:** Add corn kernels to the hashbrown mixture for a subtle sweetness and texture.
