Ingredients

• 1 pound ground beef
• 1 small onion, diced
• 3–4 cups potatoes, peeled and diced (Yukon gold or russets work great)
• 1 (15 oz) can corn, drained
• 1 (15 oz) can kidney or pinto beans, drained and rinsed
• 1 (10.5 oz) can cream of mushroom or cream of chicken soup
• 1 (14.5 oz) can diced tomatoes, undrained
• ½ cup sour cream
• 1 cup shredded cheddar cheese, plus more for topping
• 1 teaspoon garlic powder
• 1 teaspoon smoked paprika
• Salt and pepper, to taste
• Fresh parsley or green onions, for garnish (optional)

Step-by-Step Instructions

1. Brown the beef and onion

In a large skillet over medium heat, cook the ground beef and onion until beef is browned and onions are soft (about 5–7 minutes). Season lightly with salt and pepper.

Drain any excess grease.

2. Load the slow cooker

In your slow cooker, layer in the following:

• Diced potatoes
• Cooked ground beef and onions
• Corn
• Beans
• Diced tomatoes (with their juice)
• Cream of mushroom/chicken soup
• Sour cream
• Garlic powder, paprika, and additional salt/pepper

Stir gently to combine.

3. Cook

Cover and cook on LOW for 5–6 hours or HIGH for 3–4 hours, until the potatoes are fork-tender and everything is hot and bubbly.

4. Add cheese

About 15 minutes before serving, stir in 1 cup of shredded cheddar cheese.

Top with a little extra cheese if desired, and cover just until melted.

5. Serve and garnish

Spoon into bowls and garnish with chopped parsley or green onions, if you like. Serve with warm rolls or cornbread for the ultimate comfort meal.

How to Serve

This cowboy casserole is satisfying all on its own, but it’s even better with:

• Buttery cornbread or biscuits
• A simple green salad
• Pickles or sliced jalapeños on the side
• Hot sauce or BBQ sauce for a flavor boost
• Crushed tortilla chips for a little crunch on top

Tips for Success

1. Cut potatoes small and even – So they cook through evenly.
2. Don’t skip browning the beef – Adds flavor and removes excess grease.
3. Use a liner or cooking spray – To make cleanup super easy.
4. Adjust seasoning to taste – Especially after adding soup and sour cream.
5. Add cheese at the end – It stays gooey and doesn’t get overcooked.

Variations

• Spicy Cowboy Casserole – Add diced green chiles or a dash of cayenne.
• Turkey or chicken version – Use ground turkey or shredded rotisserie chicken.
• No canned soup? – Use ½ cup sour cream + ½ cup milk and a tablespoon of flour for a homemade creamy base.
• Tex-Mex twist – Use black beans, taco seasoning, and top with jalapeños and cilantro.
• Veggie version – Use lentils or mushrooms instead of ground meat.
