Preheat oven to 350 degrees. F. Prepare 2 loaf pans 9 X5 inch, sometimes I use a 9 X 13 inch cake pan. No matter which you choose, prepare it with cooking spray.

In a large bowl, add all of the ingredients except for the glaze: the ground beef, eggs, milk, bread, onion, carrots, salt, and pepper. Using your hands, mix the ingredients until incorporated.

Transfer the ground beef mixture between the loaf pans or add to the cake pan.

In a clean bowl, combine the ketchup, brown sugar, and mustard. Spread this on top of the ground beef mixture.

Bake for 1 hour 30 minutes or until meatloaf is cooked through. A thermometer inserted into the center should read at least 160 degrees F. 70 degrees C. Let cook a few minutes. Cut into slices and serve.
