Step‑by‑Step Instructions for Slow Cooker Cowboy Potato Casserole

Step 1: Brown Ground Beef
In a large skillet over medium-high heat, brown 1 pound of ground beef, breaking it into crumbles with a spatula. After about 5–7 minutes, add 1 chopped yellow onion and sauté until softened and translucent. For the final minute, stir in 2 minced garlic cloves, then drain any excess grease to prevent a watery casserole.

Step 2: Combine in Slow Cooker
Transfer the browned beef mixture to your slow cooker. Add 1 package of frozen diced potatoes, 1 cup of whole kernel corn, and a can of Rotel diced tomatoes with green chilies. These ingredients will create the comforting base of your Slow Cooker Cowboy Potato Casserole, combining savory and sweet flavors that everyone will love.

Step 3: Prepare Creamy Sauce
In a medium bowl, whisk together 1 can of condensed cream of mushroom soup and 1 cup of beef broth or milk until smooth and creamy. This mixture will help bind the casserole together, ensuring a rich consistency. Pour the creamy sauce evenly over the ingredients in the slow cooker, allowing it to seep in and enhance every bite.

Step 4: Season
Sprinkle 1 teaspoon of paprika, 1 teaspoon of chili powder, and 1 teaspoon of garlic powder over the mixture in the slow cooker, adding in any optional parsley flakes. Season with salt and black pepper to taste. Use a large spoon to gently stir everything together, ensuring the flavors meld beautifully in your Slow Cooker Cowboy Potato Casserole.

Step 5: Cook
Cover the slow cooker and cook on LOW for 6-8 hours or on HIGH for 3-4 hours. This slow, thorough cooking allows the potatoes to become tender and the flavors to develop fully, turning your casserole into a bubbling, mouth-watering meal. Try to avoid lifting the lid during cooking to maintain an even temperature.

Step 6: Add Cheese
In the last 30 minutes of cooking, sprinkle 1.5 cups of shredded sharp cheddar cheese over the top of the casserole. Replace the lid to allow the cheese to melt into a gooey layer atop the hearty mixture. The sight of melted cheese atop your Slow Cooker Cowboy Potato Casserole will have everyone eagerly anticipating dinner.

Step 7: Serve
Once the cooking time is up, carefully sprinkle any remaining cheese and optional crispy fried onions for added texture. Serve the Slow Cooker Cowboy Potato Casserole warm, allowing its creamy and hearty goodness to come to life on your dinner table. This comforting dish is perfect for gatherings or cozy family nights.

Make Ahead Options

These Slow Cooker Cowboy Potato Casserole is a fantastic choice for meal prep enthusiasts, allowing you to save precious time on busy weekdays! You can brown the ground beef (along with the onion and garlic) up to 24 hours in advance and store it in an airtight container in the refrigerator.

When you’re ready to cook, simply add the prepped beef back into the slow cooker, season, and set to cook as directed. This way, you’ll enjoy a comforting, home-cooked dish that’s just as delicious as if you made it all in one go!

Slow Cooker Cowboy Potato Casserole Recipe FAQs

How long can I store leftovers of the casserole?

What should I do if my casserole seems too watery?
If your casserole ends up watery, it could be from excess grease in the ground beef or too much liquid in the ingredients. To fix it, simply drain the grease before combining everything in the slow cooker. Additionally, you can thicken it further by letting it cook longer with the lid off for the last hour.

Is this casserole safe for dogs?

You can easily create a vegetarian version by substituting the ground beef with plant-based meat alternatives or black beans. Make sure to also use vegetable broth instead of beef broth, and skip the bacon or fried onions if you’re looking for a completely meat-free dish!
