At 350°F (175°C), a typical rule of thumb for cooking meatloaf is 35 to 45 minutes per pound (454 grams) of meatloaf. However, several factors can influence the cooking time:
-
Size and shape: A larger or thicker meatloaf will take longer to cook through compared to a smaller or thinner one.
-
Ingredients: Meatloaves with denser ingredients like more meat or less filler might cook slightly faster than those with a lot of breadcrumbs or vegetables.
-
Internal temperature: The most reliable way to ensure your meatloaf is cooked through is to check its internal temperature.
Here's a breakdown of cooking time based on weight:
-
1-pound (454 grams) meatloaf: 35-45 minutes
-
1.5-pound (680 grams) meatloaf: 50 minutes to 1 hour and 5 minutes
-
2-pound (907 grams) meatloaf: 1 hour to 1 hour and 10 minutes
-
Larger meatloaves (over 2 pounds): These can take up to 1 ½ to 2 hours, depending on the thickness and density.
Tips for perfectly cooked meatloaf at 350°F:
-
Use a meat thermometer: The safest way to ensure doneness is to check the internal temperature. The center of the meatloaf should reach 160°F (71°C).
-
Loaf shape: Form the meatloaf into a loaf that's relatively even in thickness for consistent cooking.
-
Basting (optional): Basting the meatloaf occasionally with pan drippings or glaze can add moisture and flavor, but it's not essential.
-
Letting it rest: After removing the meatloaf from the oven, tent it with foil and let it rest for 10-15 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful meatloaf.

Remember, these are guidelines. The best way to determine if your meatloaf is done is to use a meat thermometer and check the internal temperature.
