Ingredients and Their Purpose

1.5 pounds ground beef – The hearty protein base of the casserole, providing rich, savory flavor and satisfying texture.
1 onion, chopped – Adds natural sweetness and depth, balancing the richness of the beef and cheese.
3 cloves garlic, minced – Enhances the overall flavor with aromatic warmth and savory complexity.
4 cups cubed potatoes – The comforting backbone of the dish; they soak up flavor and become melt-in-your-mouth tender.
1 teaspoon salt – Essential for seasoning every layer and bringing all flavors together.
½ teaspoon black pepper – Adds mild heat and enhances the savory notes.
1 teaspoon paprika – Contributes gentle smokiness and a subtle warmth.
1 cup beef broth – Keeps the casserole moist while infusing deep beefy flavor throughout.
2 cups shredded cheddar cheese – Provides sharp, classic cheesiness and irresistible melt.
1 cup shredded mozzarella cheese – Adds creamy stretch and balances the cheddar’s boldness.
¼ cup fresh parsley (optional) – A fresh, vibrant garnish that brightens the finished dish.

Step-by-Step Instructions

Heat a skillet over medium heat. Add the ground beef, chopped onion, and minced garlic. Cook until the beef is fully browned and the onion is soft and fragrant. Drain excess fat to prevent greasiness.
Lightly grease your slow cooker. Add half of the cubed potatoes in an even layer at the bottom.
Spoon half of the beef mixture over the potatoes. Sprinkle with half of the salt, black pepper, and paprika.
Repeat the layers with the remaining potatoes and beef, finishing with the rest of the seasonings.
Slowly pour the beef broth over the entire casserole, allowing it to seep through the layers.
Cover and cook on LOW for 6–7 hours, or until the potatoes are fork-tender and infused with flavor.
About 30 minutes before serving, sprinkle the cheddar and mozzarella cheese evenly over the top. Cover again and allow the cheese to melt into a bubbly, golden layer.
Garnish with fresh parsley if desired and serve hot.
