Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. Heat 1 tbsp olive oil in a large skillet over medium heat. Add 1/2 cup diced onion and 2 cloves minced garlic, sauté for 3-4 minutes until softened and fragrant.
  2. Step 2: Add 1 lb ground beef to the skillet, breaking it up with a spoon. Cook for 6-8 minutes until browned and no longer pink. Season with 1 tsp salt, 1/2 tsp black pepper, 1/2 tsp dried oregano, and 1/4 tsp dried thyme.
  3. Step 3: Reduce heat to low and stir in 4 oz cream cheese and 1/4 cup heavy cream. Cook, stirring constantly, until the cream cheese melts and the sauce thickens, about 2-3 minutes.
  4. Step 4: Transfer the mixture to a greased 8x8-inch baking dish and evenly sprinkle 1 1/2 cups shredded sharp cheddar cheese on top.
  5. Step 5: Bake uncovered for 15 minutes until cheese is melted and bubbly. Let cool 5 minutes before serving.
