how long deo you cook a 3 pound meatloaf. It depends on what kind of container you're cooking it in. The thicker the meatloaf (i.e. cooked in a breadpan), the longer the cooking times. If you're cooking a 3-lb. loaf, I recommend using something larger than a standard baking pan....something like a lasagne baking pan.That way, the cooking time will be reduced. If you do this, it should be ready in an hour at 375.1  In a meat loaf pan-A good rule seems to be 1/2 hour per pound. 2  Then letting it sit for 10 minutes before slicing it. 3  Make your gravy while the meatloaf sets.hat way, the cooking time will be reduced.

Best Answer: i would do one of the following.. The rule of thumb is 2 hours. Because lunch meat contains so much salt and preservatives, I'd eat it after 8 or 9 hours left out( and have). The chance of spoilage is of course is always there. But after just 4 or 5 hours, I would just refrigerate it. I am pretty careful about following HACCP( safe food handling and temp control) but in this case, knowing that companies pump these products, the chances are slim that they would go bad in 4 or 5 or 6 hours.
