How to Make It

Prepare to enjoy a hearty dish with these simple steps:

Brown the beef

In a skillet over medium heat, cook the ground beef with the chopped onion and minced garlic. Stir occasionally until the beef is browned and the onions are softened. Drain any excess fat.

Combine ingredients

Transfer the beef mixture to your slow cooker. Add the cream of mushroom soup, milk, kidney beans, diced tomatoes with green chilies, frozen corn, chili powder, salt, and pepper. Stir until evenly combined.

Add potatoes

Layer the sliced potatoes on top of the beef and bean mixture, ensuring the potatoes are well coated in the sauce.

Cook

Cover and cook on low for 6–7 hours or on high for 3–4 hours, until the potatoes are tender and fully cooked.

Melt the cheese

About 20 minutes before the cooking time is up, sprinkle the shredded cheese evenly over the top. Cover and allow the cheese to melt completely.

Serve

Once the cheese is melted and bubbly, spoon the casserole onto plates or bowls. Serve warm and enjoy!
