🛒 Ingredients
1 pound ground beef
The ground beef provides the hearty, savory foundation of the casserole. Browning it first adds deeper flavor and removes excess grease before it goes into the slow cooker.
1 bag frozen hash browns
Frozen hash browns make this recipe especially convenient. They create a hearty potato layer that absorbs the flavorful juices from the beef and creamy sauce as everything cooks.
1 packet taco seasoning
Taco seasoning gives the ground beef its signature Tex-Mex flavor with a convenient blend of spices. It adds plenty of savory seasoning without requiring a long list of individual spices.
1 can cheddar cheese soup
Cheddar cheese soup forms the rich, creamy base of the sauce. It helps bind the casserole together while adding concentrated cheesy flavor.
1 cup sour cream
Sour cream adds creaminess and a subtle tang that balances the richness of the beef and cheese.
2 cups shredded cheddar cheese
Cheddar is what gives this casserole its irresistible gooey, melted cheese topping. For the best melt, freshly shredded cheese works particularly well.
1 can diced tomatoes with green chiles
Tomatoes add moisture and brightness, while the green chiles provide a mild kick and classic Southwestern flavor.
2 green onions, sliced
Green onions add a fresh finishing touch and a little contrast to the rich, creamy casserole.
👩🍳 How to Make Slow Cooker John Wayne Casserole
Step 1: Brown the ground beef
Place the ground beef in a large skillet over medium-high heat. Cook until completely browned, breaking it apart with a spoon as it cooks.
Drain any excess grease.
Step 2: Season the beef
Return the beef to the skillet and stir in the taco seasoning.
Mix thoroughly so the seasoning coats the meat evenly.
Step 3: Add the hash browns
Spray the inside of your slow cooker lightly with nonstick cooking spray if desired.
Add the frozen hash browns and spread them into an even layer across the bottom.
There is no need to thaw them first.
Step 4: Layer the seasoned beef
Spoon the seasoned ground beef evenly over the hash browns.
Try to distribute the beef from edge to edge so every serving gets a little of everything.
Step 5: Make the creamy mixture
In a medium bowl, combine the cheddar cheese soup, sour cream, and diced tomatoes with green chiles.
Stir until everything is thoroughly incorporated.
Step 6: Add the creamy layer
Spread the creamy tomato mixture evenly over the seasoned ground beef.
Use the back of a spoon or spatula to gently smooth the surface.
Step 7: Add the cheese
Sprinkle the 2 cups of shredded cheddar cheese evenly over the top.
This creates the delicious cheesy layer that melts into the casserole as it cooks.
Step 8: Slow cook
Cover the slow cooker with its lid.
Cook on LOW for 4–5 hours, or until the casserole is heated through and hot and bubbly.
Because slow cookers vary, begin checking toward the lower end of the cooking time.
Step 9: Garnish and serve
Once finished, sprinkle the casserole with sliced green onions.
Let it rest for a few minutes before serving so the layers can settle slightly.

💡 Pro Tips for the Best John Wayne Casserole
Don’t skip browning the beef. It develops better flavor and allows you to drain away excess grease.
Keep the hash browns frozen when adding them to the slow cooker unless your package specifically requires thawing.
Spread each layer evenly for consistent flavor and texture throughout the casserole.
Use freshly shredded cheddar when possible for a smooth, attractive melt.
Watch the cooking time. Slow cookers vary, so check the casserole around 4 hours.
Let it rest briefly before serving. A few minutes helps the casserole become easier to scoop.
Adjust the heat to your preference. Choose mild or hotter diced tomatoes with green chiles depending on how spicy you like your casserole.

Try serving it with:
