Step 1: Prepare the oven. Preheat it to 375 degrees F. Using a nonstick spray, grease a 9 x 13-inch baking dish and set aside.
Step 2: Place the beef, bread crumbs, egg, onion, nutmeg, garlic powder, salt, and pepper in a large bowl. Mix well until just combined. Scoop and roll 1 ½ tablespoons of the mixture into a ball. Repeat with the remaining mixture.
Step 3: In a large skillet, heat the olive oil over medium-high heat. To the hot oil, add the meatballs and cook until all sides are browned. To a plate, transfer the meatballs and set aside.
Step 4: In the meantime, cook the noodles in a large pot of salted boiling water for two minutes less than the package directions.
Step 5: Add the broth, heavy cream, and Worcestershire sauce to the now-empty skillet and scrape up any browned bits on the bottom of the pan. Allow the mixture to simmer for about 10 minutes until a little thickened. To taste, season with salt and pepper. Then, take the skillet off the heat.
