Swedish Meatball Pasta Bake

Bake frozen meatballs for about 12 minutes at 350°F (175°C). Boil 1 1/2 cups pasta according to package directions. While pasta cooks, melt 3 tablespoons butter in a pan. Whisk in 1/4 cup flour until combined, then gradually add 2 cups beef broth, stirring constantly to avoid lumps. Stir in 3/4 tablespoon Worcestershire sauce, salt, pepper, onion powder, and garlic powder to taste. Bring to a simmer until thickened. Remove from heat and stir in 1/4 cup heavy cream or half & half. Combine the cooked pasta, baked meatballs, and sauce in a baking dish. Top with Parmesan cheese. Bake at 375°F (190°C) for 30 minutes.
