Ingredients

1 (22 ounce) jar Alfredo sauce
3 cups less-sodium beef broth
1 tablespoon Worcestershire sauce
½ cup sour cream, at room temperature
12 ounces uncooked medium egg noodles
1 cup frozen diced onion thawed
14 ounces frozen fully-cooked meatballs, thawed
8 ounces sliced fresh mushrooms
2 teaspoons minced garlic
½ cup panko breadcrumbs
1 tablespoon salted butter, melted
Optional garnish: chopped fresh parsley

Instructions

Preheat oven to 425F (220C). Spray your largest baking dish (I used a deep 9 x 13-inch dish) with cooking spray.
In the prepared dish (or in a separate bowl), whisk together the Alfredo sauce, beef broth, Worcestershire sauce, and sour cream until smooth and completely combined. Stir in the uncooked noodles, onion, meatballs, mushrooms, and garlic. Cover tightly with aluminum foil and bake for 30 minutes.
Uncover; stir. At this point you should check the pasta to make sure that it is almost al dente (firm but just about finished cooking). If it’s still too hard, cover the dish and return to the oven until pasta is al dente. Then move on to the next step.
In a small bowl, mix together breadcrumbs and melted butter. Sprinkle breadcrumbs over casserole and bake, uncovered, until the noodles are al dente, about 5 more minutes. If you'd like the topping more toasted and browned, you can place the dish under the broiler for a minute or two at the end (just keep a close eye on it so that it doesn't burn).
Let the casserole sit and rest for at least 5-10 minutes before serving. The sauce will thicken slightly as it sits, and the noodles will continue to soften. Garnish with fresh parsley, if desired.

Notes

Cooking for a Smaller Family? Cut all of the ingredients in half and bake the casserole in an 8-inch square dish. Cooking instructions remain the same.
