Instructions

  1. Step 1: Preheat oven to 400°F. In a large bowl, combine 1 lb ground beef, 1 egg, 1/4 cup almond flour, 1 tsp garlic powder, 1 tsp salt, 1/2 tsp black pepper, and 1/4 cup grated parmesan cheese. Mix gently until just combined.
  2. Step 2: Form the mixture into 12 equal meatballs, then press a 1/2-inch cube of mozzarella cheese into the center of each, sealing the meat around the cheese completely.
  3. Step 3: Heat 2 tbsp olive oil in a large oven-safe skillet over medium-high heat. Add meatballs and brown on all sides for about 4-5 minutes total, turning carefully to avoid breaking.
  4. Step 4: Transfer the skillet to the oven and bake meatballs for 8-10 minutes until cooked through and cheese is melted inside.
  5. Step 5: While meatballs bake, melt 1 tbsp butter in a saucepan over medium heat. Add 8 oz sliced mushrooms and sauté for 5-6 minutes until golden and fragrant.
  6. Step 6: Pour in 1/2 cup chicken broth and simmer for 2 minutes. Stir in 1 cup heavy cream and 1 tsp fresh thyme leaves, cooking for 4-5 minutes until sauce thickens and coats the back of a spoon.
  7. Step 7: Remove meatballs from oven and transfer to the mushroom sauce. Spoon sauce over meatballs and serve immediately.
