Ingredients
For the Casserole
- 1 lb ground beef
- 1 bag frozen hash browns
- 1 packet taco seasoning
- 1 can cheddar cheese soup
- 1 cup sour cream
- 2 cups shredded cheddar cheese
- 1 can diced tomatoes with green chiles, undrained
- 2 green onions, sliced
Ingredient Notes
Ground beef: Lean or regular ground beef works well. If using regular ground beef, drain the excess grease after browning so the casserole does not become overly oily.
Frozen hash browns: Shredded frozen hash browns are convenient and work particularly well in this casserole. There is no need to thaw them first unless your particular slow cooker recipe requires it.
Taco seasoning: Store-bought taco seasoning keeps the recipe quick and easy, but you can also use your favorite homemade taco seasoning blend.
Cheddar cheese soup: This creates a creamy, cheesy base and helps bring all the layers together.
Sour cream: Sour cream adds a creamy texture and balances the richness of the cheese and beef.
Diced tomatoes with green chiles: These add moisture, acidity, and a mild kick of Tex-Mex flavor. Use a mild variety for a family-friendly casserole or a spicier version if you prefer more heat.
Cheddar cheese: Freshly shredded cheddar melts beautifully and gives the casserole its irresistible golden, cheesy topping.
How to Make Slow Cooker John Wayne Casserole
1. Brown the Ground Beef
Begin by heating a large skillet over medium heat. Add the ground beef and cook, breaking it apart with a wooden spoon or spatula as it browns.
Continue cooking until the beef is completely browned and no longer pink. Carefully drain any excess grease from the skillet.
Return the beef to the skillet and stir in the taco seasoning. Mix well so the seasoning coats the beef evenly and allow it to cook for another minute or two.
2. Prepare the Slow Cooker
Lightly grease the inside of your slow cooker with cooking spray or a small amount of oil. This helps make serving and cleanup easier.
Add the frozen hash browns to the bottom of the slow cooker and spread them into an even layer.
There is no need to cook the hash browns first. They will soften and cook as the casserole slowly heats.
3. Add the Seasoned Beef
Spoon the taco-seasoned ground beef evenly over the hash brown layer.
Try to distribute the beef across the entire surface so every serving gets a good combination of potatoes and seasoned meat.
4. Make the Creamy Layer
In a medium bowl, combine the cheddar cheese soup, sour cream, and diced tomatoes with green chiles.
Stir until the ingredients are thoroughly combined and the mixture looks creamy and evenly blended.
This mixture creates the rich center of the casserole and adds plenty of flavor to the beef and potatoes.
5. Layer the Creamy Mixture
Spread the creamy tomato and cheddar mixture evenly over the seasoned ground beef.
Use the back of a spoon or spatula to gently spread it across the casserole without disturbing the layers too much.
6. Add the Cheese
Sprinkle the shredded cheddar cheese evenly over the top.
The cheese will melt slowly during cooking, creating a rich, gooey topping that ties all of the ingredients together.
7. Slow Cook
Cover the slow cooker with the lid and cook on LOW for 4–5 hours, or until the casserole is hot, bubbly, and the hash browns are tender.
Cooking times can vary depending on the slow cooker, so begin checking toward the earlier end of the cooking range if your slow cooker tends to run hot.
Try to avoid lifting the lid repeatedly because doing so allows heat to escape and can increase the cooking time.
8. Add the Green Onions
Once the casserole is finished, remove the lid and sprinkle the sliced green onions generously over the melted cheese.
The fresh green onions add a bright flavor and a little crunch that contrasts beautifully with the creamy casserole.
Let the casserole rest for a few minutes before serving. This allows the layers to settle slightly and makes it easier to scoop.
Tips for the Best Casserole
For the best texture, spread each layer as evenly as possible. This helps ensure that the hash browns, beef, creamy mixture, and cheese cook together consistently.
Do not skip draining the beef if it releases a lot of grease. Too much excess fat can make the finished casserole greasy rather than creamy.
Freshly shredded cheddar cheese is an excellent choice because it tends to melt smoothly and evenly. You can use sharp cheddar for a stronger cheese flavor or mild cheddar for a softer, family-friendly taste.
If you enjoy spicy food, consider using hot diced tomatoes with green chiles or adding a pinch of crushed red pepper flakes or cayenne pepper to the beef.
Serving Suggestions
Serve this casserole hot with a simple green salad, steamed vegetables, or roasted vegetables for a complete meal.
You can also add your favorite toppings just before serving. Sour cream, sliced jalapeños, fresh cilantro, avocado, salsa, or extra green onions all work wonderfully with the Tex-Mex flavors.
For a casual gathering, serve the casserole directly from the slow cooker and let everyone add their favorite toppings.
Variations
Chicken Version: Replace the ground beef with shredded cooked chicken and use taco seasoning for a delicious chicken variation.
Spicy Version: Add diced jalapeños, hot green chiles, or extra chili seasoning for more heat.
Extra Cheesy: Mix a little Monterey Jack or pepper Jack cheese with the cheddar for an extra gooey topping.
Vegetable Version: Add corn, black beans, diced bell peppers, or chopped zucchini for additional texture and flavor.
Bacon Cheeseburger Style: Add cooked, crumbled bacon and replace part of the taco seasoning with a little garlic and onion seasoning for a different flavor profile.
Storage and Reheating
Allow leftover casserole to cool before transferring it to an airtight container. Refrigerate for up to 3–4 days.
Reheat individual portions in the microwave until hot throughout, or reheat larger portions in an oven-safe dish until warmed through.
The casserole may also be frozen in suitable airtight containers. For best texture, thaw it in the refrigerator before reheating.
