How to Make Longhorn-Style Cheesy Ground Beef and Potato Casserole

Step 1: Prepare the Potatoes

Preheat your oven to 375°F (190°C).

Wash and thinly slice the potatoes. Try to keep the slices similar in thickness so they cook evenly.

Place the potato slices in a bowl and toss them with:

Olive oil or melted butter
Salt
Pepper
Paprika

Set aside while preparing the beef mixture.

Step 2: Cook the Ground Beef

Heat a large skillet over medium heat.

Add the ground beef and cook until browned, breaking it apart with a spoon as it cooks.

Drain excess grease if needed.

Add the chopped onion and cook for 3–4 minutes until softened.

Stir in the garlic and cook for another 30 seconds until fragrant.

Add:

Tomato paste
Worcestershire sauce
Smoked paprika
Garlic powder
Onion powder
Chili powder
Salt
Pepper

Mix well and allow the flavors to combine for a few minutes.

Remove from heat.

Step 3: Prepare the Creamy Cheese Mixture

In a bowl, combine:

Sour cream
Cream cheese
Milk or heavy cream
Garlic powder
Black pepper

Mix until smooth and creamy.

Fold in half of the shredded cheddar and Monterey Jack cheese.

This creates the rich, cheesy layer that makes the casserole extra satisfying.

Step 4: Assemble the Casserole

Lightly grease a 9×13-inch baking dish.

Arrange half of the sliced potatoes in an even layer.

Spread half of the cooked ground beef mixture over the potatoes.

Add half of the cheese sauce.

Repeat the layers:

Remaining potatoes
Remaining beef mixture
Remaining cheese sauce

Finish with the remaining shredded cheese on top.

Step 5: Bake Until Golden and Delicious

Cover the casserole with foil and bake for about 40 minutes.

Remove the foil and continue baking for another 15–20 minutes until:

The potatoes are tender
The cheese is melted and golden
The edges are bubbling

For an extra golden topping, you can broil for 1–2 minutes at the end, keeping a close eye to prevent burning.

Allow the casserole to rest for 10 minutes before serving.

Tips for the Best Casserole

Slice Potatoes Thinly

Thin slices cook more evenly and create a softer, more enjoyable texture.

A mandoline slicer can make the process faster and more consistent.

Use Freshly Shredded Cheese

Pre-shredded cheese is convenient, but freshly shredded cheese often melts more smoothly because it contains fewer added anti-caking ingredients.

Season Every Layer

Potatoes need seasoning too. Adding spices directly to the potato layer creates better flavor throughout the casserole.

Let It Rest Before Serving

Allowing the casserole to sit for a few minutes helps the layers set and makes serving easier.

Delicious Variations

Bacon Cheeseburger Casserole

Add cooked bacon pieces and pickles for a cheeseburger-inspired twist.

Spicy Southwest Version

Add:

Jalapeños
Taco seasoning
Pepper jack cheese
Green chilies

for extra flavor and heat.

Vegetable Beef Casserole

Add vegetables such as:

Bell peppers
Mushrooms
Corn
Spinach
Peas

for additional nutrition and texture.

Ranch Cheesy Potato Casserole

Mix ranch seasoning into the cheese sauce and top with crispy bacon for a popular flavor combination.

What to Serve With This Casserole

This dish is filling on its own, but it pairs well with lighter sides.

Try serving it with:

Fresh garden salad
Steamed vegetables
Roasted broccoli
Green beans
Garlic bread
Coleslaw

A simple side helps balance the richness of the casserole.

Frequently Asked Questions

Can I make this casserole ahead of time?

Yes. Assemble the casserole, cover it tightly, and refrigerate for up to 24 hours before baking.

You may need to add a few extra minutes to the cooking time if baking directly from the refrigerator.

Can I use frozen potatoes?

Yes. Frozen diced or shredded potatoes can work, but cooking times may vary. Make sure excess moisture is removed to prevent a watery casserole.

What cheese works best?

Cheddar and Monterey Jack create a classic creamy flavor, but you can also use mozzarella, Colby, or a cheese blend.

Can I use ground turkey instead of beef?

Absolutely. Ground turkey is a lighter alternative and works well with the same seasonings.
