Notes
Ground meat: Meatloaf can be made with any combination of ground meat, or just one kind of ground meat. Nutrition information is calculated using ground beef (95/5).
Faster cooking alternative: Form the meatloaf mixture into 6 mini loaves. Place on a rimmed baking pan, sides not touching. Bake at 400°F for 25 minutes or until done (165°F internal temp).
