stir 1–2 cups of cooked, shredded chicken or diced ham into the noodles before pouring on the soup mixture.
If you like extra onion flavor, add 1/2 teaspoon onion powder or a handful of finely chopped sautéed onions to the soup and sour cream mixture. To stretch the dish for a crowd, you can add up to 1/2 cup of milk or cream to the soup mixture for a bit more sauce, adjusting the baking time by about 5 minutes if needed.
