  • Total Time: 55 minutes
  • Yield: 8 servings

Ingredients

Meat Mixture

  • 2 lbs. ground beef (93% lean, 7% fat)
  • 1 1/4 cup chopped onion
  • 3 cloves garlic, minced
  • 2 teaspoons Worcestershire sauce
  • 1 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1 teaspoon paprika
  • Salt and pepper to taste

Potatoes & Cheese

  • 3 medium Russet potatoes, sliced into 1/4” rounds (skin on)
  • 1 cup mozzarella cheese
  • 1 cup sharp cheddar cheese

Cream Sauce

  • 1 cup milk (plant-based or whole)
  • 1/2 cup beef broth
  • 3/4 cup Greek yogurt
  • 2 1/2 tbsp butter
  • 2 1/2 tbsp gluten-free all-purpose flour
  • Salt and pepper to taste

Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish with cooking spray or butter to prevent sticking.
  2. Make Meat Mixture: In a large skillet over medium heat, brown the ground beef until no longer pink. Drain all excess fat thoroughly to keep the casserole from being greasy. Add chopped onion and minced garlic, cooking for an additional 2-3 minutes until the onion softens. Stir in Worcestershire sauce, garlic powder, onion powder, and paprika. Remove from heat and set aside.
  3. Make Roux and Cream Sauce: In a separate saucepan, melt butter over medium heat. Whisk in gluten-free flour and cook for 1-2 minutes to form a smooth roux. Gradually whisk in milk and beef broth until the sauce thickens smoothly. Remove from heat and stir in Greek yogurt. Season with salt and pepper to taste. This creamy sauce adds richness and binds the casserole layers.
  4. Build Casserole Layers: Place half of the sliced potatoes evenly on the bottom of the prepared baking dish. Spread half of the cooked ground beef mixture over the potatoes. Pour and spread half of the cream sauce over the beef layer. Repeat the layering with the remaining potatoes, ground beef, and cream sauce evenly.
  5. Add Cheese and Bake: Sprinkle the mozzarella and sharp cheddar cheese evenly over the top of the layered casserole. Cover the dish with aluminum foil and bake for 45-50 minutes, or until the potatoes are tender. Remove the foil and bake for an additional 10-15 minutes until the cheese is melted, bubbly, and slightly golden. Let cool a few minutes before serving.

Notes

  • Ensure you drain all the ground beef fat to prevent a greasy casserole.
  • You can substitute the roux-based cream sauce with a thickened dairy-free sauce or condensed soup if preferred.
  • Leaving the potato skins on adds texture and nutrition but peel if desired.
  • Use plant-based milk and dairy-free cheese to adapt this for a vegan diet.
  • This casserole reheats well the next day and can be frozen before baking for meal prep.
