Cooking Instructions

In a large skillet over medium heat, brown the ground beef with the chopped onion and minced garlic until the meat is cooked through. Drain any excess fat.

Mix everything well to combine all the ingredients.

Cover the slow cooker and cook on low for 6-7 hours or on high for about 4 hours. Stir occasionally if possible.

Serving Up Your Cowboy Potato Casserole
This casserole is perfect to serve straight from the slow cooker. You can scoop generous portions onto plates or into bowls. It pairs wonderfully with a fresh salad or some crusty bread to soak up the creamy goodness.
Storing Leftovers
To store any leftovers, allow the casserole to cool completely. Transfer it to an airtight container and refrigerate. It will keep well for 3-4 days. Reheat in the microwave or in the oven until warmed through.
Tips for the Perfect Casserole
- Don’t skip browning the beef; it adds flavor to the dish.
- Feel free to adjust the seasonings according to your taste. If you love heat, consider adding jalapeños or a splash of hot sauce.
- Use pre-cooked, frozen potatoes to save even more time!
Variations to Try
If you’re looking for a twist, you can substitute the ground beef with ground turkey for a healthier option. You can also mix and match different cheeses, like pepper jack for a spicy kick or mozzarella for a milder flavor.
