Recipe Overview

Prep Time: 15 minutes
Cook Time: 45 minutes
Total Time: 1 hour
Servings: 6-8
Yield: One 13×9 casserole dish
Dietary Type: Not specified (Contains dairy)

Ingredients

2 lbs frozen hash browns (shredded)
½ cup butter, melted
1 (14 ounce) can beef broth
1 small yellow onion, diced
3 tablespoons instant minced onion
2 cups Monterey Jack cheese, Colby cheese blend, shredded
2 cups sharp cheddar cheese, shredded
1 teaspoon salt
½ teaspoon fresh ground pepper

Equipment Needed

13 x 9 inch oven-safe casserole dish
Large mixing bowl
Measuring cups and spoons
Oven

Instructions

Begin by preheating your oven to 350 degrees Fahrenheit. This ensures the casserole cooks evenly and the cheese melts to a golden brown perfection.
Next, prepare your 13×9 inch oven-safe casserole dish. A light coating of cooking spray is essential to prevent the casserole from sticking. Using a butter-flavored cooking spray adds an extra layer of richness that complements the other ingredients beautifully.
In a large mixing bowl, combine all the ingredients, except for the 2 cups of sharp cheddar cheese. This includes the 2 pounds of frozen shredded hash browns, ½ cup of melted butter, the 14-ounce can of beef broth, the diced yellow onion, 3 tablespoons of instant minced onion, 2 cups of the Monterey Jack and Colby cheese blend, 1 teaspoon of salt, and ½ teaspoon of fresh ground pepper.
Thoroughly mix all the ingredients until they are evenly distributed. This ensures that every bite is packed with flavor and cheesy goodness. Be gentle while mixing to avoid breaking down the hash browns too much.
Pour the mixture into the prepared casserole dish, spreading it evenly to ensure uniform cooking.
Bake in the preheated oven for 30 minutes. This initial baking period allows the flavors to meld together and the casserole to start setting.
After 30 minutes, remove the casserole from the oven and sprinkle the remaining 2 cups of sharp cheddar cheese evenly over the top.
Return the casserole to the oven and bake for an additional 15 minutes, or until the cheese is melted, bubbly, and lightly golden brown. Keep a close eye on it to prevent the cheese from burning.
Once the cheese is perfectly melted and golden, remove the casserole from the oven and let it rest for a few minutes before serving. This allows the casserole to set slightly and makes it easier to cut and serve.

Expert Tips & Tricks

Beef Broth Alternative: If you don’t have beef broth on hand, chicken broth or vegetable broth can be used as a substitute. The flavor profile will change slightly, but the casserole will still be delicious. For a richer flavor, consider using bone broth.
Cheese Variations: Feel free to experiment with different types of cheese. Pepper jack cheese adds a spicy kick, while Gruyere or Swiss cheese provides a nutty, complex flavor.
Crispy Hash Browns: For extra crispy hash browns, spread the mixture in a thin layer in the casserole dish and broil for the last few minutes of cooking, keeping a close watch to prevent burning.
Make-Ahead Prep: You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours before baking. Add an extra 10-15 minutes to the baking time if baking directly from the refrigerator.
Onion Flavor Boost: For a more intense onion flavor, sauté the diced yellow onion in a little butter until softened before adding it to the mixture.
Preventing Soggy Casserole: To avoid a soggy casserole, ensure that the frozen hash browns are well-drained before adding them to the mixture.

Serving & Storage Suggestions

This Cheesy Onion Hash Brown Casserole is a versatile dish that can be served as a side dish for breakfast, brunch, lunch, or dinner. It pairs perfectly with grilled meats, roasted vegetables, or a simple salad. For a complete brunch, serve it alongside scrambled eggs, bacon, and fresh fruit.

To store leftovers, let the casserole cool completely before covering it tightly with plastic wrap or transferring it to an airtight container. Store in the refrigerator for up to 3-4 days.

To reheat, bake in a preheated oven at 350 degrees Fahrenheit until heated through, or microwave individual portions. The microwave can sometimes make the hash browns a bit soggy, so the oven is the preferred method for reheating.

This casserole can also be frozen for longer storage. Wrap the cooled casserole tightly in plastic wrap and then in aluminum foil, or transfer it to a freezer-safe container. It can be stored in the freezer for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
