Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. In a large bowl, combine 1 lb ground beef, 1 large egg, 1/4 cup almond flour, 1 tsp garlic powder, 1 tsp onion powder, 1 tsp salt, and 1/2 tsp black pepper. Mix gently until just combined.
  2. Step 2: Divide mixture into 12 equal portions. Flatten each portion, place one 1/3 oz cube of mozzarella cheese (4 oz total divided into 12) in the center, and carefully form meatballs sealing the cheese inside.
  3. Step 3: Heat 2 tbsp olive oil in a large oven-safe skillet over medium-high heat. Brown meatballs on all sides, about 3 minutes per side, then transfer skillet to the oven and bake for 8 minutes.
  4. Step 4: While meatballs bake, in a separate pan, sauté 8 oz sliced mushrooms over medium heat until golden and soft, about 5 minutes. Add 1 cup heavy cream and 1 tsp fresh thyme leaves, simmering until the sauce thickens and coats the back of a spoon, about 5 minutes.
  5. Step 5: Remove meatballs from oven and add to the mushroom sauce, gently stirring to coat. Serve warm.
