Doubling meat loaf recipe - can I turn up heat and how much longer to bake
Using a meat loaf recipe that calls for a 1 lb of meat. Have doubled that and most ingredients. Original recipe calls for 1 hour at 350oF oven.
Any suggestions on if I can turn up the heat to cook faster and how much longer to cook it for?
Do not turn up the heat. A 2-lb meat loaf will take about 90 minutes at 350, if you're baking it in a regular loaf pan, maybe even less. Mine will tend to be more like 3 lbs, and I put it and a couple of big greased Idahos at the same time and everything usually gets done more or less at once, even with my frequently opening the door to draw off excess fat.
This is actually one of the best arguments for getting a remote thermometer...
Use a probe thermometer and take out your meat loaf when the internal temperature of the meat loaf reaches 160 F. With a probe thermometer, you don't have to worry about under/over cooking.
