Ingredients
- 1 lb, 80% lean ground beef
- 4 oz, cut into 12 small cubes sharp cheddar cheese
- 1 large egg
- 1/4 cup almond flour
- 2, minced garlic cloves
- 1 tsp salt
- 1/2 tsp black pepper
- 2 tbsp olive oil
- 8 oz, sliced mushrooms
- 1/2 cup heavy cream
- 1/2 cup beef broth
- 1 tsp, chopped fresh thyme
Instructions
- Step 1: Preheat oven to 400°F. In a mixing bowl, combine 1 lb ground beef, 1 large egg, 1/4 cup almond flour, 2 minced garlic cloves, 1 tsp salt, and 1/2 tsp black pepper. Mix gently until just combined.
- Step 2: Divide the meat mixture into 12 equal portions. Flatten each portion and place a 1/3 oz cube of sharp cheddar cheese (total 4 oz cut into 12 cubes) in the center, then form meat around the cheese to seal and shape into balls.
- Step 3: Heat 2 tbsp olive oil in an oven-safe skillet over medium-high heat. Brown the meatballs for 2-3 minutes per side until golden but not cooked through.
- Step 4: Remove meatballs and set aside. In the same skillet, add 8 oz sliced mushrooms and sauté for 5 minutes until browned and soft.
- Step 5: Pour in 1/2 cup beef broth and 1/2 cup heavy cream, scraping browned bits from the pan. Stir in 1 tsp chopped fresh thyme and simmer for 3 minutes until sauce thickens slightly.
- Step 6: Return meatballs to the skillet, spoon sauce over them, and transfer skillet to the oven. Bake for 10 minutes until meatballs are cooked through and cheese inside is melted.
- Step 7: Serve hot, spooning extra creamy mushroom sauce over the meatballs.
