For an extra layer of flavor, consider browning the ground beef and pork before mixing. Drain off any excess grease. If you like a bit of heat, add an extra pinch or two of red pepper flakes. To keep the meatloaf moist, you can add a tablespoon or two of olive oil to the meat mixture. Let the meatloaf rest for 10 minutes before slicing and serving. This helps the juices redistribute, resulting in a more tender meatloaf.
