Why You'll Love This Recipe
About the Ingredients
1 pound (450g) ground beef
Ground beef adds a rich, meaty flavor to the casserole. If you don't have it, use ground turkey or a plant-based alternative.
1 medium russet potato, peeled and cubed
Russet potatoes provide a soft, slightly fluffy texture. If they are not available, use Yukon Gold or any starchy potato.
1 can (15 ounces) kidney beans, drained and rinsed
Kidney beans add protein and heartiness. Use black beans or pinto beans if kidney beans are not in stock.
1 can (15 ounces) corn, drained
Corn brings a sweet, crunchy element. If you prefer a crunchier texture, use frozen corn instead.
1 cup (240ml) tomato sauce
Tomato sauce is the foundation of the flavor. Use homemade or a high-quality store-bought option for the best taste.
1 cup (200g) shredded cheddar cheese
Cheddar cheese adds a creamy and melty quality. If it's not available, use mozzarella or a Mexican blend.
1/2 cup (120ml) water
Water helps the sauce thicken and mix well with the other ingredients. You can use beef broth for extra depth of flavor.
1/2 teaspoon garlic powder
Garlic powder gives the dish a savory depth. Substitute with fresh minced garlic if you have it on hand.
Step-by-Step Instructions
1. Brown the Beef
Heat a skillet over medium-high heat. Add ground beef and cook until no longer pink, about 5 minutes. Drain excess fat.
2. Prepare the Potatoes
Peel and cube the potato. If time allows, lightly sauté or microwave it for 2–3 minutes until slightly softened.
3. Combine Ingredients
Place the browned beef, cubed potato, kidney beans, corn, and tomato sauce in the slow cooker. Stir well to mix all ingredients evenly.
4. Add Cheese and Season
Sprinkle the shredded cheddar cheese over the top. Add water and garlic powder. Mix gently to combine.
5. Cook the Casserole
Cook on high for 3–4 hours or low for 6–7 hours. The potatoes should be tender and the sauce bubbling around the edges.
6. Check for Doneness
After cooking, lift the lid and check that the casserole is fully bubbled and the potatoes are soft. If not, cook for 15–30 minutes longer on high.
7. Serve and Enjoy
Garnish with extra cheese or green onions if desired. Serve hot, ideally with a side of bread or salad.
