Ingredients List: Pantry Staples and Affordable Additions
Here’s everything you’ll need to make this mouthwatering casserole:
- 1 pound ground beef
- 1 small yellow onion, finely chopped
- 2 cloves garlic, minced
- 1 can (15 oz) red kidney beans, drained and rinsed
- 1 can (15 oz) whole kernel corn, drained
- 1 can (14.5 oz) diced tomatoes, undrained
- 1 can (10.5 oz) cream of mushroom soup
- ½ cup sour cream
- 2 cups frozen hash brown potatoes
- 1 ½ cups shredded cheddar cheese
- 1 tsp paprika
- 1 tsp salt
- ½ tsp black pepper
- 1 tbsp olive oil (for sautéing)
- Optional: chopped parsley or green onions for garnish
Step-by-Step Instructions: From Prep to Plate
Step 1: Sauté the Beef Mixture
In a large skillet, heat olive oil over medium heat. Add ground beef and cook until browned. Stir in the chopped onion and garlic, and cook for another 3–4 minutes until softened and fragrant. Drain excess fat if needed. This step adds a layer of flavor that can’t be achieved by dumping everything raw into the cooker.
Step 2: Combine Core Ingredients
In a large mixing bowl, combine the cooked beef mixture with the drained kidney beans, corn, diced tomatoes, cream of mushroom soup, sour cream, paprika, salt, and pepper. Stir until all ingredients are evenly blended. This ensures that every spoonful is filled with flavor.
Step 3: Prepare the Slow Cooker
Spray the inside of your slow cooker with non-stick spray or use a liner for easy cleanup. Layer the frozen hash brown potatoes at the bottom. Next, spoon the beef and bean mixture evenly over the potatoes. Smooth the top with a spatula to create an even layer.
Step 4: Let It Cook
Cover the slow cooker and set it to low for 5–6 hours or high for 3–4 hours. The slow cooking allows all the flavors to develop and come together.
Step 5: Add the Cheese
About 20 minutes before serving, sprinkle the shredded cheddar cheese evenly over the casserole. Cover the lid again and cook until the cheese is fully melted and bubbly. This creates a gooey, cheesy topping that’s hard to resist.
