Ingredients:

• 1 lb (450g) ground beef
• 1 medium onion, diced
• 3 cloves garlic, minced
• 3-4 large potatoes, peeled and sliced thinly
• 1 red bell pepper, diced (optional)
• 2 cups (200g) shredded cheddar cheese (divided)
• 1 cup (240ml) beef broth
• 1 cup (240ml) heavy cream
• 1 tablespoon olive oil
• 1 tablespoon butter
• 1 teaspoon smoked paprika
• 1 teaspoon dried oregano
• Salt and pepper to taste
• Fresh parsley for garnish (optional)

Instructions:

1. Preheat the oven to 375°F (190°C) and grease a large baking dish.
2. Prepare the beef mixture:
   • Heat olive oil in a skillet over medium heat.
   • Add the diced onions and cook for 3-4 minutes until soft.
   • Add garlic and red bell pepper (if using), cooking for another 1-2 minutes.
   • Add the ground beef, breaking it apart with a spoon as it cooks. Season with smoked paprika, oregano, salt, and pepper.
   • Cook the beef until browned and cooked through. Set aside.
3. Prepare the potatoes:
   • Thinly slice the peeled potatoes (about ⅛ inch thick).
   • Arrange half of the potato slices in an even layer at the bottom of the greased baking dish.
4. Make the cream mixture:
   • In a small saucepan, melt the butter over low heat.
   • Stir in the beef broth and heavy cream. Heat gently until combined, but do not boil. Season lightly with salt and pepper.
5. Assemble the casserole:
   • On top of the first layer of potatoes, spread half of the cooked beef mixture.
   • Pour half of the cream mixture over the beef and potatoes.
   • Sprinkle 1 cup of shredded cheddar cheese over the layer.
   • Add another layer of sliced potatoes, then the remaining beef mixture.
   • Pour the remaining cream mixture evenly over the top.
   • Sprinkle the remaining 1 cup of shredded cheddar cheese over the entire dish.
6. Bake:
   • Cover the dish with foil and bake in the preheated oven for 40 minutes.
   • After 40 minutes, remove the foil and bake for an additional 15-20 minutes, or until the cheese is golden brown and bubbly, and the potatoes are tender.
7. Serve:
   • Let the casserole cool for a few minutes, then garnish with fresh parsley.
   • Serve warm and enjoy!

This cheesy, hearty casserole would be perfect for a family dinner or a cozy meal. You can also add variations like bacon bits, green onions, or swap out the cheese type for a different flavor profile.
