How to Make Slow Cooker Cowboy Potato Casserole
-
Cook Beef and Vegetables: In a large skillet, brown 1½ pounds of ground beef along with chopped onion, minced garlic, and diced red bell pepper over medium heat for about 5-7 minutes. Once the meat is fully cooked, be sure to drain any excess fat for a better flavor.
-
Prepare Sauce: In a mixing bowl, whisk together the cream of mushroom soup, milk, salt, black pepper, and paprika until the mixture is smooth and creamy. This will be the flavorful heart of your casserole.
-
Layer in Slow Cooker: Begin by placing half of the diced potatoes at the bottom of the slow cooker. Layer on half of the beef mixture followed by half of the sauce. Repeat these layers with the remaining ingredients, ensuring an even distribution.
-
Cooking Time: Cover the slow cooker and cook on low heat for 5-6 hours. You’ll know it’s ready when the potatoes have become tender and the flavors have melded beautifully.
-
Add Cheese: About 20 minutes before you’re ready to serve, sprinkle 1 cup of shredded cheddar cheese over the top. Cover again and let it cook on low until the cheese is perfectly melted and bubbly.
-
Serving Preparation: Once it's done, allow the casserole to sit for about 5 minutes before serving. This will help solidify the layers a touch, making it easier to serve. Finish off with a sprinkle of chopped parsley for that pop of color!
Optional: Feel free to add a dollop of sour cream on top just before serving for an enriched creaminess.

Slow Cooker Cowboy Potato Casserole Recipe FAQs

What if my casserole is too watery?
If you find your casserole is a bit watery, this often happens if there are too many starchy sauces or moisture-rich veggies.
