The best temperature to cook the meatloaf at is 350°F and it requires about 1 hour, give or take a few minutes, depending on size and shape.

The Basic Meatloaf Formula All recipes for meatloaf start with the same basic formula: 2 pounds of ground meat and a “panade” made of bread or crackers soaked in milk. Along with a few eggs, this panade helps to hold the ground meat together and adds some essential moisture to the mix.

The only way to guarantee tender meat is not to overcook it. And that's a simple matter of using a thermometer when you bake the meatloaf. Milk does, on the other hand, add moisture and fat and is worth including for that fact alone.

When this happens, it's because you didn't use enough. Next time, try adding in an extra egg and/or some more breadcrumbs. Alternatively, rice, barley, corn flakes, crackers, and dried soup mix can also stand in as binding ingredients as well. Including larger quantities of these items should help solve the problem.
