This recipe may be doubled and frozen for future meals. After baking, remove the meatloaf muffins from the pan to cool. Wrap each individual portion with aluminum foil and freeze. To reheat: Thaw overnight in the refrigerator or on your counter for about 4 hours. Preheat the oven to 375 degrees F. Place the thawed muffins on a baking sheet in their foil packets and bake for 25 minutes. Carefully open the foil and continue to bake for 5 minutes until warmed through.
