Ingredients You’ll Need

Simple ingredients make this recipe shine. Each element plays a crucial role in delivering the rich, savory flavor and creamy texture that defines this Slow Cooker Cheeseburger Casserole.

• 2 pounds ground beef: The star protein providing a juicy, meaty base full of flavor when seasoned well.
• 1/2 cup onion, diced: Adds a subtle sweetness and aromatic depth when sautéed with the beef.
• 2 tablespoons relish: Brings a burst of tangy sweetness that balances the savory flavors perfectly.
• 2 tablespoons dry mustard or yellow mustard: Gives the dish a mild kick and sharp undertone reminiscent of a classic cheeseburger.
• 8 ounces tomato sauce or ketchup: Adds acidity and moisture, infusing the casserole with that familiar burger sauce flavor.
• 1 1/2 teaspoons salt (or more): Essential for enhancing all the layers of taste.
• 1/2 teaspoon pepper: Provides a gentle seasoning boost without overpowering the dish.
• 3 cups cheddar cheese (or more): The gooey, melty cheese that makes every bite so comforting and indulgent.
• 4 medium-size soft flour tortillas: These create the perfect tender layers, soaking up all those meaty juices and cheese.

How to Make Slow Cooker Cheeseburger Casserole

Step 1: Brown the Ground Beef and Onions

Start by heating a large skillet over medium heat and adding the seasoned ground beef along with the diced onions. Cook everything together for about 5 to 7 minutes, stirring frequently to crumble the beef as it browns and letting the onions soften into sweetness. Once the meat is fully cooked and the onions translucent, drain any excess grease. This foundation will create a rich, savory base for the casserole.

Step 2: Combine Ingredients in the Skillet

Next, stir in the relish, mustard, salt, pepper, and tomato sauce or ketchup directly into your browned beef mixture. Let it cook together for a few minutes until everything is heated through and the flavors meld beautifully. This mixture captures that classic cheeseburger zing with a little extra flair from the relish.

Step 3: Prepare the Slow Cooker

Before assembling, generously spray the inside of your slow cooker with cooking spray to ensure the casserole won’t stick. This makes cleanup a snap and helps keep the cheese and meat layers looking picture-perfect when served.

Step 4: Layer the Casserole

Divide the meat mixture into three equal portions. Start by spreading one portion in the bottom of the slow cooker, then top with one cup of cheddar cheese. After that, lay two soft flour tortillas over the cheese, overlapping them if needed to cover the surface. Repeat these layers twice more: meat mixture, cheese, tortillas, finishing off with a final layer of cheddar on top. This layering ensures every bite is packed with that perfect balance of meat, cheese, and soft tortillas.

Step 5: Slow Cook to Perfection

Cover the slow cooker and cook on HIGH for 2 to 3 hours or on LOW for 4 to 6 hours. The slow heat gently melts the cheese and infuses the tortillas with all the savory juices from the beef mixture, creating a melty, tender casserole that’s full of flavor. Check towards the end to ensure the cheese is bubbly and the casserole is heated through.

How to Serve Slow Cooker Cheeseburger Casserole

Garnishes

This casserole shines on its own, but adding fresh garnishes can elevate it even more. Sprinkle chopped fresh parsley or green onions on top for a pop of color and a fresh bite. For those who love a little heat, a few dashes of hot sauce or sliced jalapeños bring an exciting twist.

Side Dishes

Pair your Slow Cooker Cheeseburger Casserole with crisp, refreshing sides to cut through the richness. A simple green salad with a tangy vinaigrette, steamed vegetables like broccoli or green beans, or even a crunchy coleslaw are perfect companions. For a heartier meal, roasted potatoes or sweet potato fries always complement cheeseburger flavors beautifully.

Creative Ways to Present

Want to impress your guests or family? Serve the casserole layered in individual ramekins for a charming single-serving presentation. Alternatively, top it with crispy fried onions or a drizzle of barbecue sauce for an unexpected twist that still harmonizes with the cheeseburger theme.

Make Ahead and Storage

Storing Leftovers

Once cooled, transfer leftovers to an airtight container and refrigerate for up to 3 days. The flavors actually deepen after resting a bit, making your Slow Cooker Cheeseburger Casserole just as delicious — if not more — the next day.

Freezing

This casserole freezes beautifully. To freeze, layer the casserole in a freezer-safe dish and cover tightly with foil or plastic wrap. It will keep well for up to 2 months. When you’re ready to enjoy it, thaw overnight in the fridge before reheating.

Reheating

Reheat leftover casserole in the microwave or oven until warmed through. If using an oven, cover lightly with foil to prevent the cheese from browning too much and bake at 350°F (175°C) for about 20 minutes, depending on the portion size.

FAQs

Can I use ground turkey or chicken instead of beef?

Absolutely! Ground turkey or chicken can be swapped in for beef to create a lighter version of this casserole. Just be mindful that ground poultry cooks slightly faster, so adjust cooking times as needed.

Is it necessary to use tortillas in the casserole?

While tortillas add a tender, chewy layer that soaks up all the sauce and cheese beautifully, you can experiment with subbing in bread slices or even cooked pasta for a different texture. Just keep in mind cooking times may vary.

Can I prepare this Slow Cooker Cheeseburger Casserole ahead of time?

Yes! You can fully assemble the casserole the night before, cover it tightly, and refrigerate it. The next day, just pop it in the slow cooker and adjust the cooking time slightly since the ingredients will be cold.

What type of cheese works best?

Sharp cheddar is the classic choice for its bold flavor and melting quality, but feel free to mix in cheeses like Monterey Jack or mozzarella for a creamier texture and different flavor profile.

How spicy is this Slow Cooker Cheeseburger Casserole?

It’s mild and savory by default, with the mustard providing a gentle tang but no real heat. You can add a little cayenne or hot sauce if you enjoy a spicier twist.
