It reheats well for leftovers and can be adapted to different ground meats if you prefer. Simple to assemble and crowd-pleasing, it pairs nicely with a fresh green salad or steamed vegetables.

Ingredients

1.5 lbs ground beef (or any preferred ground meat)
Use your favorite ground meat; beef gives a classic taco flavor but turkey or chicken work too.
1 yellow onion, diced
Adds sweetness and depth when cooked with the meat.
2 tbsp taco seasoning
Provides the primary taco flavor for the meat layer.
3/4 cup water
Helps dissolve and meld the taco seasoning into the meat for a saucier filling.
30 oz bag frozen hash browns, partially thawed
The base of the casserole; partially thawed makes mixing easier.
1 can (10.5 oz) Campbell’s Cheddar Cheese Soup
Adds creamy cheese flavor and binds the hash browns.
1 cup sour cream
Gives creaminess and a mild tang to the potato layer.
1 can (10 oz) Ro-Tel (diced tomatoes + green chilies)
Adds tomato, mild heat, and a touch of acidity.
1 tbsp taco seasoning
Extra seasoning for the hash brown mixture to boost taco flavor.
8 oz shredded pepper jack cheese, divided
Pepper jack brings creamy heat; reserve half for layering and half for topping.
8 oz shredded sharp cheddar cheese, divided
Sharp cheddar adds tangy, melty cheesiness; split between layers and topping.
About half a (9.25 oz) bag of Doritos Nacho Cheese Doritos, crushed (or any flavor you like)
Crushed chips create a crunchy, flavorful crust; choose your preferred Doritos flavor.

Step-by-Step Instructions

Preheat your oven to 350°F (175°C) and grease a baking dish.
Lightly oil or spray a 9×13 inch dish for easy serving and cleanup.
In a skillet over medium heat, cook the ground beef and diced onion until browned. Drain excess fat, then return the skillet to heat.
Tip: Cook until the beef is no longer pink and the onion is translucent.
Add 2 tablespoons taco seasoning and 3/4 cup water to the skillet; simmer for about 5 minutes.
Stir occasionally so the seasoning dissolves and the sauce thickens slightly.
In a large mixing bowl, combine the partially thawed hash browns, cheddar cheese soup, sour cream, Ro-Tel, and 1 tablespoon taco seasoning; mix well.
Make sure the hash browns are evenly coated so the casserole bakes uniformly.
In the greased baking dish, spread half of the hash brown mixture; press gently.
Use the back of a spatula to level the layer for even baking.
Layer with half of the taco meat and half of the shredded cheeses. Repeat the layers with remaining ingredients.
Build a second hash brown layer, then the remaining meat, then the remaining pepper jack and sharp cheddar.
Top evenly with crushed Doritos.
Spread the chips across the surface so the top crisps up in the oven.
Cover with foil and bake for 30 minutes, then remove foil and bake for another 15-20 minutes until bubbly and golden.
The uncovered time allows the top to brown and the cheeses to bubble.
Allow to cool for a few minutes before serving.
Letting it rest makes slicing easier and helps the layers set.

Tips, Storage & Variations

Tips

Partially thaw the hash browns just enough to separate them easily; fully thawed potatoes can be too wet.
Drain excess fat from the cooked meat to prevent a greasy casserole.
Press layers gently so the casserole bakes evenly and slices cleanly.

Storage

Refrigerate leftovers in an airtight container for up to 3 days. Reheat portions in the oven at 350°F until warmed through, or microwave on medium heat in short intervals.

Freezing

To freeze, assemble the casserole but do not bake. Wrap tightly with plastic and foil, and freeze for up to 2 months. Thaw in the refrigerator overnight, then bake as directed, adding a few extra minutes if still cold.

Variations using existing ingredients only

Swap the ground beef for any preferred ground meat listed in the ingredients to lighten or change the flavor profile.
Use only pepper jack or only sharp cheddar if you prefer one cheese flavor more strongly.
Change the Doritos topping to a milder or spicier flavor to adjust the crunch and overall heat level.

FAQ

Can I use fresh potatoes instead of frozen hash browns?
Fresh potatoes are not listed in the ingredient list, so use the provided frozen hash browns for best results.
Do I need to thaw the hash browns completely?
No, partially thawing makes them easier to mix while preventing excess moisture.
Can I make this ahead of time?
Yes, assemble the casserole, cover, and refrigerate up to 24 hours before baking.
How spicy will this casserole be?
The Ro-Tel and pepper jack add mild to medium heat; reduce pepper jack or use a milder Doritos flavor to tone it down.
Is there a recommended baking dish size?
A 9×13 inch baking dish works well to fit the layers evenly.
