Instructions

1. Step 1: In a large bowl, combine 1 lb ground beef, 1 large egg, 1/4 cup almond flour, 1 tsp salt, 1/2 tsp black pepper, and 1 minced garlic clove. Mix gently until combined.
2. Step 2: Take about 2 tbsp of the meat mixture and flatten into a small patty. Place a 1/2-inch cube of sharp cheddar cheese in the center and wrap the meat around it, forming a sealed meatball. Repeat to make about 12 meatballs.
3. Step 3: Heat 2 tbsp olive oil in a large skillet over medium-high heat. Brown the meatballs on all sides, about 3-4 minutes per side, then remove and set aside.
4. Step 4: In the same skillet, add 1 minced garlic clove and 8 oz sliced mushrooms. Sauté for 5 minutes until mushrooms soften and release their aroma.
5. Step 5: Pour in 1/2 cup chicken broth and 1 cup heavy cream, stirring to combine. Add 1 tsp chopped fresh thyme. Simmer for 3-4 minutes until the sauce thickens slightly.
6. Step 6: Return the meatballs to the skillet, spoon sauce over them, and cook for an additional 5 minutes until meatballs are cooked through and cheese inside is melted. Serve hot.
