Well, depending on the size of the meatloaf, the baking time would be different. I used to always make meatloaf in a bread pan because that is the way mom used to make it. When I make one in a bread pan, I bake for at least 45 minutes up to 1 hour. I alway cut an end slice out to make sure the ground beef is fully cooked.
I cook my meatloaf at 350 for 1 hour, uncovered
If you are using a standard loaf pan for your meatloaf, you would cook it 1 hour in a 350 preheated oven.
About an hour, depending on the size.
I cook my Meatloaf at 400 for about 45min - 1 hour depending on size of meatloaf
