How long should you cook a 2.3 pound meatloaf?

Here's a more detailed guide:

* Internal temperature: The meatloaf is done when it reaches an internal temperature of 160°F (71°C) for safe consumption.

* Cooking time: The cooking time can vary depending on the size and shape of the loaf and your oven.

* Check for doneness: After about an hour, insert a meat thermometer into the thickest part of the loaf. If it's not yet at 160°F, continue cooking for another 10-15 minutes.

* Resting time: Allow the meatloaf to rest for 10 minutes before slicing to allow the juices to redistribute.

Important Note: This is an estimate, and it's always best to use a meat thermometer to ensure the meatloaf is cooked through.
