To make this recipe gluten free, simply substitute gluten free breadcrumbs for the traditional breadcrumbs.I like to place the loaf pan on a baking sheet in the oven, just in case any grease or sauce bubbles over the loaf pan while baking.Don't have a loaf pan? No worries, you can free form the meatloaf into a loaf shape and cook it on a foil lined baking sheet.If serving the meatloaf with pasta on the side, be sure to boil the water and cook the pasta during the last 15 minutes of baking the meatloaf.
