    INGREDIENTS

    • 1 pound ground beef
    • 1 medium onion, chopped
    • 3 cups potatoes, diced
    • 1 (15 oz) can red kidney beans, drained and rinsed
    • 1 (15 oz) can corn, drained
    • 1 (10 oz) can diced tomatoes with green chiles
    • 1 (10.5 oz) can cream of mushroom soup
    • 1 cup shredded cheddar cheese
    • 1 teaspoon garlic powder
    • ½ teaspoon paprika
    • Salt and pepper, to taste

    DIRECTIONS

    • Step No.1: Brown the beef
      In a skillet over medium heat, cook the ground beef with chopped onion until browned. Drain excess fat before transferring to the slow cooker.

    • Step No.2: Add vegetables and beans
      Add diced potatoes, kidney beans, corn, and diced tomatoes with green chiles into the slow cooker with the beef mixture.

    • Step No.3: Stir in soup and spices
      Add the cream of mushroom soup, garlic powder, paprika, salt, and pepper. Stir everything together until well combined.

    • Step No.4: Slow cook it
      Cover and cook on low for 6–7 hours or on high for 3–4 hours, until potatoes are tender.

    • Step No.5: Add cheese
      Sprinkle shredded cheddar cheese on top during the last 15 minutes of cooking. Let it melt completely before serving.

    TIPS FOR SUCCESS

    • Brown beef thoroughly: Cooking the beef and onions well develops deeper flavours and reduces grease in the final dish.

    • Drain excess fat: This prevents a greasy casserole and helps the seasoning stick better to the meat and veggies.

    • Use fresh or canned beans: Rinsing canned beans helps reduce sodium and keeps flavours clean.

    • Don’t skip the crushed chips: They add a delightful crunchy texture that contrasts perfectly with the creamy casserole.

    • Stir before serving: This helps distribute all the ingredients and melted cheese evenly.

    • Adjust spice to taste: Add more chili or hot sauce if you prefer extra heat in your casserole.

    VARIATIONS

    • Add bell peppers: Diced red or green bell peppers bring a fresh crunch and extra nutrition to the casserole.

    • Make it vegetarian diet: Swap ground beef for plant-based meat or extra beans for a hearty vegetarian version.

    • Top with sour cream: A dollop of sour cream adds creaminess and balances the spices perfectly.

    • Add jalapeños: For those who love heat, sliced jalapeños add a spicy kick that wakes up every bite.

    • Use smoked cheese: Smoked cheddar or gouda gives the dish a rich, smoky flavour that’s hard to resist.

    • Serve with rice or tortilla: Spoon casserole over cooked rice or serve with warm tortillas for a complete meal.

    SERVING AND STORAGE

    Serving

    Serve warm straight from the slow cooker with crusty bread, biscuits, or a green side salad for a full meal.

    Storage

    Store leftovers in an airtight container in the fridge for up to 4 days or freeze for up to 2 months.

    FAQ

    Can I prep this the night before?

    Yes! Assemble the ingredients in the slow cooker insert, cover, and refrigerate overnight. Cook the next day as directed.

    Do I have to brown the beef first?

    Yes, for best flavour and texture. It also prevents excess grease in the finished dish.

    Can I use frozen vegetables?

    Yes, just stir them in during the last hour of cooking so they don’t get too soft.

    Is this spicy?

    It’s mild as written. Add extra chiles or hot sauce to increase the heat.

    Can I cook it on high?

    Yes, 3–4 hours on high works if you're short on time—just stir halfway through.

    It’s packed with flavour from seasoned beef, creamy soup, tender potatoes, and a cheesy finish.

    Best of all, everything comes together in one pot, making both cooking and cleanup simple.

    Whether you’re feeding a family on a busy weeknight or bringing a dish to a gathering, this casserole is always a hit.

    About Sana Umer

    I'm Sana Umer — the home cook behind every recipe on For Foodie Friends. I'm a Pakistani-American mom of two based in the US, and I've been cooking seriously for about a decade now, mostly because feeding a family every day is the fastest way to learn how to actually cook.

    I'm completely self-taught. I learned by watching my mother in Pakistan, by burning a lot of food in my early years, and by paying attention to which recipes worked and which ones needed fixing. I don't specialize in just one cuisine — I cook the Pakistani dishes I grew up with, the American desserts my kids request, weeknight dinners, holiday roasts, and everything in between.

    Every recipe is personally tested in my own kitchen, every word is written by me, and every photo is taken of food I actually made.

    Hi, I'm Sana Umer — the home cook, recipe tester, and writer behind For Foodie Friends.

    I'm a Pakistani-American mom based in the US. I learned to cook in two kitchens — my mother's in Pakistan, where I grew up watching whole spices bloom in oil, and my own kitchen now, where I cook for my husband and kids.

    Every recipe on this site has been tested in my own kitchen, often more times than I'd like to admit, before it ever made it here. I cook a little bit of everything: the Pakistani comfort food I grew up with, the American desserts my kids beg for, weeknight dinners that need to come together fast, and the holiday spreads that take all day.

    If a recipe is on this site, it earned its place. No ghostwriters, no AI shortcuts, no copy-paste from somewhere else — just real recipes from a real kitchen, written to actually work the first time you make them.

    Welcome to my corner of the internet.

    — Sana
