What is the Best Internal Temperature for Meatloaf?

The ideal internal temperature for meatloaf is 160°F-165°F. This ensures the ground meat is fully cooked through without becoming tough and dry.

Safety is also a consideration when determining the proper internal temp. Ground meats like those used in meatloaf require thorough cooking to destroy any harmful bacteria that may be present. Heating the meatloaf to 160°F is hot enough to eliminate risks.

So when testing your meatloaf for doneness, aim for an internal temperature between 160-165°F. Use an instant read thermometer inserted into the thickest part of the loaf to check.

How to Keep a 3 lb Meatloaf Moist While Cooking

The keys to a moist, tender meatloaf are controlling the cooking temperature and preventing overcooking. Here are some useful tips:

  • Avoid overpacking: Resist the urge to compact the meat mixture tightly. This can restrict airflow and lead to uneven cooking. Shape the meatloaf mixture lightly.
  • Brush with oil: Coat the loaf pan and surface of the raw meatloaf with oil. This helps prevent sticking and creates a barrier against moisture loss.
  • Use a meat thermometer: Monitor the internal temp and remove the meatloaf once it reaches 160-165°F. Overcooking dries out the meat.
  • Let it rest: Allow the cooked meatloaf to rest tented in foil for 10-15 minutes before slicing. This allows the juices to reabsorb back into the meat.
  • Add moisture: Incorporate items like eggs, onions, tomatoes, bell peppers, broth, ketchup, milk, or yogurt into the meatloaf mixture. They add extra moisture and flavor.

Following these simple methods will help guarantee your 3 lb meatloaf baked at 375°F stays tender and juicy every time.

What is the Best Way to Test Meatloaf for Doneness?

Picture this – the timer goes off, but how can you be sure your meatloaf is fully cooked without overdoing it? Here are some reliable ways to test for doneness:

  • Use an instant read thermometer: Insert the probe into the center of the meatloaf and check the temperature reads 160-165°F. This guarantees it’s safe to eat.
  • Check internal color: A properly cooked meatloaf will be mostly brown throughout with no traces of pink. Poke it with a knife to peek inside.
  • Do a knife test: Insert a knife into the thickest part of the meatloaf and check that the juices run clear rather than pink when the knife is removed.
  • Check for firmness: Press the center with your finger. The meat should feel very firm with no mushiness.

The thermometer is the most foolproof way, but using multiple tests helps ensure your meatloaf is cooked through without cutting into it too soon. Remove it from the oven as soon as it tests done to prevent overbaking.

Step-by-Step Cooking Time for a 3 lb Meatloaf at 375°F

Now that you know what to look for, let’s discuss the ideal cooking times for a 3 pound meatloaf at 375°F:

  1. Form the meatloaf mixture into a loaf shape in a pan lightly coated with oil.
  2. Bake at 375°F for 45 minutes initially. This allows the exterior to brown and cooks a portion of the inside.
  3. After 45 minutes, begin checking the internal temperature every 5-10 minutes until it registers 160°F. This may take 15-25 more minutes.
  4. Once the center reaches 160°F, remove it from the oven immediately. The temperature will rise slightly as it rests.
  5. Let the meatloaf rest for 10-15 minutes tented loosely in foil before serving. The total time will be approximately 60-70 minutes for a 3 lb loaf.

This method ensures even cooking throughout and prevents overbaking on the edges. Your meatloaf will turn out perfectly moist!

Common Meatloaf Mistakes to Avoid

Making meatloaf is about more than just mixing meat and tossing it in the oven. To avoid a dry, dense loaf, beware of these common pitfalls:

  • Packing the meat too tightly – This inhibits airflow and leads to uneven cooking. Shape the meatloaf lightly.
  • Not using a thermometer – Without monitoring the internal temp, it’s easy to over or undercook. Use a meat thermometer to check for doneness.
  • Baking at too high of a temperature – Excessive heat dries out the exterior before the inside cooks through. Bake at 375°F.
  • Cutting into too soon – Slicing before letting it rest causes juices to run out. Always let meatloaf rest before serving.
  • Using too lean of meat – Lean meat dries out quickly. Choose meats with higher fat content or add moisture to the mix.
  • Overmixing the meat – Too much handling activates proteins causing meatloaf to get dense. Mix just until blended.

Avoiding these issues will give you tender, juicy results every time.

FAQ About Cooking 3 lb Meatloaf at 375°F

Here are answers to some frequently asked questions about cooking a 3 pound meatloaf at 375°F:

How long does it take to cook a 3lb meatloaf at 375 degrees?

  • Plan on baking a 3 pound meatloaf for 60-70 minutes total at 375°F. Bake for 45 minutes initially, then continue cooking and checking the internal temperature every 5-10 minutes until it reaches 160°F.

What temp should I cook meatloaf at?

  • The ideal baking temperature for meatloaf is 375°F. This allows the exterior to brown while cooking the interior evenly. Higher heat risks drying out the meat.

Can I cook a meatloaf from frozen?

  • It’s best not to cook meatloaf straight from frozen. Defrost it completely first by thawing overnight in the refrigerator before baking as directed.

Should I tent foil over meatloaf?

  • Yes, tenting loosely with foil helps retain moisture as the meatloaf cooks. Remove it for the last 15 minutes to brown the top.

Do you put water in the pan when cooking meatloaf?

  • Adding a little water to the loaf pan can help add moisture. But brushing the loaf with oil achieves similar results. Use a shallow pan so the bottom doesn’t cook submerged.

Can I reheat leftover meatloaf?

  • Leftover meatloaf holds up very well. Slice it and reheat gently covered in foil at 300°F until warmed through, about 20 minutes. Take care not to overcook.

Is it better to bake meatloaf in glass or metal pan?

  • Metal pans conduct heat more evenly. But a glass baking dish also works well, just increase cook time 5-10 minutes since glass doesn’t conduct heat as quickly.

Should I glaze my meatloaf before or after cooking?

  • For maximum flavor and caramelization, it’s best to glaze meatloaf in the last 15 minutes of baking once the exterior has browned.


Cooking the perfect meatloaf is easy when you understand the keys like ideal internal temperature, preventing overcooking, and properly testing for doneness. Now that you know how long to bake a 3 lb meatloaf at 375°F, you can enjoy flavorful, juicy results.
