Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Ground beef – The hearty base of the casserole. Browning the beef before adding it to the slow cooker ensures rich flavor and prevents greasiness.

Onion – Adds sweetness and depth, blending perfectly with the beef and beans.

Garlic – A touch of garlic enhances the overall flavor and brings warmth to the dish.

Potatoes – Thinly sliced potatoes form the hearty layers that make this casserole so filling. Russet or Yukon golds work particularly well.

Kidney beans – A classic cowboy-style addition that boosts both protein and fiber, making the dish more satisfying.

Corn – Adds sweetness and texture, balancing the savory layers. Canned or frozen corn both work well.

Diced tomatoes – Bring acidity and moisture, which help tie all the flavors together during slow cooking.

Cream of mushroom soup – Gives the casserole its creamy, comforting base while helping bind everything together.

Cheddar cheese – Sharp cheddar melts beautifully into the casserole, adding that irresistible gooey, cheesy finish.

Seasonings – A mix of salt, pepper, paprika, and dried oregano enhances the earthy, savory flavors.

Directions

Start by browning the ground beef in a skillet with diced onion and garlic until the meat is no longer pink. Drain any excess fat. Meanwhile, thinly slice the potatoes. In the slow cooker, lightly grease the insert and begin layering. Place a portion of the sliced potatoes on the bottom, followed by a layer of beef, beans, corn, and tomatoes. Add a spoonful of cream of mushroom soup and sprinkle with shredded cheddar. Continue layering until all ingredients are used, finishing with a generous topping of cheese.

Cover the slow cooker with its lid and cook on low for 6–7 hours or on high for 3–4 hours, until the potatoes are tender and the casserole is bubbling. About 15 minutes before serving, give the casserole a gentle stir to combine the layers, then let it rest with the lid back on to allow the flavors to settle. Serve hot, garnished with fresh parsley or extra cheese if desired.

Servings and timing

This recipe serves 6 people generously. Prep time takes about 15 minutes, and the slow cooker does the rest in 6–7 hours on low or 3–4 hours on high. It is an ideal set-it-and-forget-it meal for busy weekdays.

Storage/reheating

Leftovers can be stored in an airtight container in the refrigerator for up to four days. To reheat, place portions in the oven at 350°F until warmed through, or heat gently in the microwave. For best results, cover with foil or a lid to keep the casserole moist. This dish does not freeze particularly well because the potatoes may change texture when thawed.

Variations and Customizations

Ground turkey or chicken – Swap out beef for a leaner protein option.

Spicy kick – Add jalapeños, chili powder, or cayenne pepper for heat.

Different beans – Black beans or pinto beans work just as well as kidney beans.

Extra veggies – Mix in bell peppers, zucchini, or spinach for added nutrition.

Tex-Mex twist – Use taco seasoning and top with sour cream and salsa before serving.

Cheese variety – Try Monterey Jack, Colby, or a Mexican blend instead of cheddar.

Creamy upgrade – Add sour cream or cream cheese to the soup mixture for an extra-rich sauce.

Crispy topping – Sprinkle crushed tortilla chips or fried onions over the casserole just before serving.
