Ingredients

1.5 lbs ground beef (or any preferred ground meat),
Use your favorite ground meat. Beef adds rich flavor and a classic taco profile.
1 yellow onion, diced,
Adds sweetness and depth when cooked with the meat.
2 tbsp taco seasoning,
For seasoning the meat and building that familiar taco flavor.
3/4 cup water,
Helps the taco seasoning create a saucy coating for the meat.
30 oz bag frozen hash browns, partially thawed,
The casserole base. Partially thawed makes them easier to mix and prevents excess ice.
1 can (10.5 oz) Campbell’s Cheddar Cheese Soup,
Adds creamy, cheesy body to the hash brown layer.
1 cup sour cream,
Gives creaminess and a slight tang to balance the cheese.
1 can (10 oz) Ro-Tel (diced tomatoes + green chilies),
Provides bright tomato flavor and mild heat.
1 tbsp taco seasoning,
Mixed into the hash brown layer for consistent taco flavor throughout.
8 oz shredded pepper jack cheese, divided,
Pepper jack brings a spicy, melty kick. You will use it in two layers.
8 oz shredded sharp cheddar cheese, divided,
Sharp cheddar adds classic tang and melt. It is also used in two layers.
About half a (9.25 oz) bag of Doritos Nacho Cheese Doritos, crushed (or any flavor you like),
Crushed Doritos add a crunchy, salty topping with extra taco-style flavor.

Step-by-Step Instructions

Preheat your oven to 350°F (175°C) and grease a baking dish. A 9×13-inch dish works well.
In a skillet over medium heat, cook the ground beef and diced onion until the meat is browned and the onion is softened. Drain excess fat, then return the skillet to the heat.
Add 2 tablespoons of taco seasoning and 3/4 cup water to the meat. Stir and simmer for about 5 minutes so the flavors meld and the sauce thickens slightly.
In a large mixing bowl, combine the partially thawed hash browns, the 10.5 oz can of Campbell’s Cheddar Cheese Soup, 1 cup sour cream, the 10 oz can of Ro-Tel, and 1 tablespoon taco seasoning. Mix until well combined.
Spread half of the hash brown mixture evenly in the greased baking dish to form the first layer.
Spoon half of the seasoned taco meat over the first hash brown layer, then sprinkle half of the shredded pepper jack and half of the shredded sharp cheddar over the meat.
Repeat with the remaining hash brown mixture, the rest of the taco meat, and the remaining cheeses to form the top cheese layer.
Sprinkle the crushed Doritos evenly over the top for a crunchy, flavorful crust.
Cover the dish tightly with foil and bake for 30 minutes. Remove the foil and bake an additional 15 to 20 minutes, until the cheese is bubbly and the top is golden.
Remove from the oven and allow the casserole to cool for a few minutes before serving. A short rest helps the layers set and makes serving neater.

Cooking tip: If your Doritos brown faster than the cheese, place them on after the uncovered bake and broil briefly for an even crunch.

FAQ

Can I use a different ground meat?
Yes. Ground turkey, chicken, or pork work fine; cook and season exactly the same way.
Do I need to thaw the hash browns fully?
No. Partially thawed hash browns are easier to mix and prevent excess water in the casserole.
Can I make this ahead and bake later?
Yes. Assemble, cover, and refrigerate for up to 24 hours before baking. Add a few extra minutes to baking time if chilled.
Is this casserole freezer friendly?
Yes. Freeze baked portions or the unbaked assembled casserole for up to 2 months. Thaw in the fridge before reheating or baking.
Can I skip the Doritos topping?
Yes. The Doritos add crunch and flavor, but the casserole is tasty without them. Consider reserving them for topping after baking if you prefer extra crunch.

Tips, Storage & Variations

Practical tips: Brown meat well and drain fat to keep the casserole from becoming greasy. Mix cheeses gently to ensure even melting. Let the casserole rest a few minutes before cutting for cleaner slices.
Storage: Refrigerate leftovers in an airtight container for up to 4 days. Reheat in the oven at 350°F until warmed through to preserve texture.
Freezing: To freeze, assemble the casserole, wrap tightly with plastic and foil, and freeze for up to 2 months. Thaw overnight in the refrigerator before baking.
Flavor variations using existing ingredients only:
- Swap ground beef for ground turkey or chicken for a lighter version.
- Use different Doritos flavors from the same bag to change the topping profile.
- Increase the pepper jack proportion for a spicier, creamier bite.
- Double the Ro-Tel for a more tomato-forward, tangy casserole.
