Ingredients
  

Main Ingredients

  • 1 lb lean ground beef
  • 4 Yukon Gold or russet potatoes thinly sliced
  • 2 cups shredded cheddar cheese divided
  • 1 onion chopped
  • 2 cloves garlic minced

Cheese Sauce

  • 2 tbsp butter
  • 2 tbsp all-purpose flour
  • 1 cup whole milk
  • 1/2 cup heavy cream
  • 1/2 tsp thyme
  • 1/2 tsp paprika
  • salt and pepper to taste

Instructions
 

  • Preheat oven to 375°F (190°C). Grease a casserole dish and set aside.
  • Brown the ground beef in a skillet over medium heat. Season with salt, pepper, and paprika. Add chopped onions and cook until soft. Stir in minced garlic and cook for another minute.
  • In a saucepan, melt butter and whisk in flour to form a roux. Gradually add milk and cream, whisking until thickened. Stir in thyme and half of the shredded cheese. Season to taste.
  • Layer the casserole: start with a layer of sliced potatoes, then beef mixture, then cheese sauce. Repeat layers and finish with remaining shredded cheese on top.
  • Cover with foil and bake for 45 minutes. Remove foil and bake an additional 15 minutes until golden and bubbly.
  • Let rest for 10 minutes before serving. Garnish with chopped chives or a dollop of sour cream if desired.

Notes

Use freshly shredded cheese for the best melt and flavor. Letting the casserole rest after baking helps it set and slice neatly. This dish also freezes and reheats well for future meals.
