- Preheat oven to 375 degrees f. In a large bowl, combine the meat loaf and mix lightly with a large wooden spoon or hands. Don't mash or the meat loaf will be dense. If meat loaf mixture is too wet, add more bread crumbs or oats 1/4 cup at a time. Place into a 9x13 baking dish or 2 two-piece loaf pans. Shape into a loaf.
- Mix ingredients for the topping and spread on meat loaf. Bake for 1 to 1 1/4 hours, or until the internal temperature is 160 degrees and the meat loaf is cooked through. Let meat loaf rest about 10 minutes after removing from oven. Doing this allows the juices time to redistribute. While meat loaf is baking, saut onion and bell pepper in bacon seasoning until soft and translucent. When serving meat loaf, top with onion and bell pepper.
