For a classic meatloaf baked at 350°F, plan on about 35–45 minutes per pound and always cook until the internal temperature reaches 160–165°F.

Quick Scoop

  • 1 lb meatloaf: about 35–45 minutes at 350°F, depending on thickness and your oven.
  • 2 lb meatloaf: about 60–75 minutes at 350°F.
  • 3 lb meatloaf: about 75–90 minutes at 350°F (some guides say up to 2 hours if very thick).
  • Frozen 1 lb meatloaf at 350°F: at least 1 hour, rotating occasionally.
  • Doneness check: use a meat thermometer in the center; it’s done at 160–165°F and juices run clear.

Simple rule of thumb

  • Use about 35–45 minutes per pound as a guide at 350°F.
  • Shape the loaf about 1–1.5 inches thick so it cooks evenly.
  • Start checking the internal temperature 10 minutes before the earliest time and leave it in until it hits 160–165°F in the center.

Think of the time as a ballpark and the thermometer as the “final judge” — once you hit 160–165°F, your meatloaf is safely cooked and ready to rest.
