Cream of mushroom soup
Diced tomatoes with green chiles (with all juices)
1½ cups shredded cheddar cheese
Salt
Black pepper
Garlic powder
Onion powder
Stir until smooth and well combined. This sauce brings creaminess, cheesiness, and just the right amount of kick.
Step 6: Pour and Spread
Pour the sauce evenly over the potatoes and beef. Use a spatula to spread it out so most of the potatoes are coated. A few uncovered edges are fine—they’ll still soften as the casserole cooks.
Step 7: Slow Cook
Cover the slow cooker with the lid and cook:
LOW: 6–7 hours
HIGH: 3–4 hours
The casserole is ready when the potatoes are fork-tender and the beef is fully cooked with no pink remaining.
Step 8: Add the Final Cheese Layer
Sprinkle the remaining ½ cup shredded cheddar cheese evenly over the top. Cover and cook for another 5–10 minutes, just until the cheese is melted and gooey.
Step 9: Rest and Serve
Turn off the slow cooker and let the casserole rest, uncovered, for about 5 minutes. This helps it thicken slightly. Scoop into bowls and serve hot.
Serving Suggestions
This cowboy potato casserole is a complete meal on its own, but it pairs well with:
A simple green salad
Steamed green beans or broccoli
Cornbread or dinner rolls
Coleslaw for contrast
Variations & Tips
Extra Smoky: Swap part of the cheddar for smoked cheddar or pepper jack cheese.
Spicier Version: Use hot diced tomatoes with green chiles and add a pinch of cayenne or crushed red pepper.
Stretch the Meal: Add a layer of frozen corn or canned black beans (drained and rinsed) on top of the beef before the potatoes.
Lighter Option: Use 93% lean ground beef and reduced-fat cheese and soup (the sauce will be slightly less rich).
Soup Substitutes: Cream of chicken or cream of celery works well if you don’t have mushroom soup.
Busy-Day Tip: Slice potatoes the night before and store them in cold water in the fridge. Drain and pat dry before using to prevent browning.
Storage & Reheating
Refrigerator: Store leftovers in an airtight container for up to 4 days.
Freezer: Freeze for up to 2 months (best frozen before adding the final cheese layer).
Reheat: Warm in the microwave or oven, adding a splash of milk or broth if needed.
