How Long Does Meatloaf Take to Cook at 400?
Cooking meatloaf at 400°F (200°C) typically requires a cooking time of approximately 50-60 minutes, or until the internal temperature reaches 160°F (71°C), ensuring it’s safe and cooked through.
The Science Behind the Meatloaf
Meatloaf, a classic comfort food, is essentially a ground meat mixture combined with breadcrumbs, eggs, seasonings, and often vegetables, then baked in a loaf pan or free-form on a baking sheet. Understanding the cooking process helps ensure a moist, flavorful, and safe end product.
Factors Influencing Cooking Time
Several factors influence the time it takes to cook meatloaf at 400°F:
- Size and Shape: A larger, thicker meatloaf will naturally require more cooking time than a smaller, thinner one. Meatloaves formed free-form on a baking sheet, allowing for greater surface area exposure, may cook slightly faster.
- Meat Mixture: The type of ground meat used (beef, pork, turkey, or a combination) can impact cooking time. Leaner meats, like ground turkey, may cook faster but can also dry out more easily.
- Oven Calibration: Not all ovens are accurately calibrated. Using an oven thermometer is crucial to ensure your oven is consistently maintaining the desired temperature.
- Ingredients: Additions like vegetables that hold a lot of moisture (onions, bell peppers) can slightly affect the cooking time, as they release steam during baking.
The Importance of Internal Temperature
Relying solely on cooking time is not a reliable method for determining doneness. Always use a meat thermometer to check the internal temperature of the meatloaf. The USDA recommends a minimum internal temperature of 160°F (71°C) for ground beef, pork, lamb, and veal. Reaching this temperature ensures that harmful bacteria are killed and the meat is safe to consume.
Steps to Cooking Meatloaf at 400°F
Here’s a basic guide to cooking meatloaf at 400°F:
- Prepare the Meatloaf Mixture: Combine ground meat, breadcrumbs, eggs, seasonings, and vegetables in a large bowl. Mix gently but thoroughly.
- Shape the Meatloaf: Form the mixture into a loaf shape. Place it in a loaf pan or on a baking sheet lined with parchment paper.
- Glaze (Optional): Brush the meatloaf with your favorite glaze, such as ketchup, BBQ sauce, or a mixture of brown sugar and vinegar.
- Bake: Bake at 400°F for approximately 50-60 minutes, or until the internal temperature reaches 160°F (71°C).
- Rest: Let the meatloaf rest for at least 10 minutes before slicing and serving. This allows the juices to redistribute, resulting in a more moist and flavorful meatloaf.
Common Mistakes to Avoid
- Overmixing: Overmixing the meatloaf mixture can result in a tough, dense meatloaf. Mix only until the ingredients are just combined.
- Using Too Much Breadcrumbs: Too many breadcrumbs can make the meatloaf dry. Use the correct proportion of breadcrumbs to meat.
- Not Checking Internal Temperature: As mentioned earlier, relying solely on cooking time is risky. Always use a meat thermometer.
- Not Allowing to Rest: Skipping the resting period can cause the meatloaf to lose moisture and become dry.
Troubleshooting a Meatloaf that isn’t Cooking Properly
If your meatloaf isn’t cooking properly (e.g., it’s taking longer than expected, or the top is browning too quickly), consider the following:
- Oven Temperature: Verify your oven temperature with an oven thermometer.
- Meatloaf Size: A larger meatloaf will naturally take longer.
- Meatloaf Pan: Dark metal pans cook faster than light-colored pans.
- Foil Cover: Covering the meatloaf with foil during part of the baking time can prevent over-browning.

FAQs: Your Meatloaf Questions Answered
How do I know when my meatloaf is done?
The best way to determine if your meatloaf is done is to use a meat thermometer. Insert the thermometer into the thickest part of the meatloaf. It should read 160°F (71°C).
Can I cook meatloaf at 400°F in a loaf pan?
Yes, you can absolutely cook meatloaf at 400°F in a loaf pan. Make sure the pan is oven-safe. Grease the pan lightly to prevent sticking. Ensure proper heat distribution.
Does covering the meatloaf with foil affect the cooking time?
Covering the meatloaf with foil during the first part of the baking process can help prevent the top from browning too quickly. However, it may slightly increase the overall cooking time. Remove the foil during the last 15-20 minutes to allow the top to brown.
What happens if my meatloaf is still pink inside at 160°F?
A slight pinkish hue in the center of the meatloaf when it reaches 160°F can be due to a chemical reaction between the myoglobin in the meat and the nitrates in some seasonings. As long as the internal temperature is 160°F, the meatloaf is safe to eat.
Can I use frozen ground meat to make meatloaf?
Yes, you can use frozen ground meat, but it’s essential to thaw it completely before mixing it with the other ingredients. Thawing ensures even cooking. Improperly thawed meat leads to uneven cooking.
What is the best way to keep meatloaf moist?
To keep meatloaf moist, avoid overmixing, use a proper ratio of breadcrumbs to meat, and don’t overcook it. Adding vegetables like onions and bell peppers can also help retain moisture.
How long should I let meatloaf rest after cooking?
Letting meatloaf rest for at least 10 minutes after cooking is crucial. This allows the juices to redistribute throughout the meat, resulting in a more moist and flavorful meatloaf.
Can I add a sauce or glaze to my meatloaf?
Yes, adding a sauce or glaze can enhance the flavor and moisture of your meatloaf. Apply the glaze during the last 15-20 minutes of baking to prevent burning. Ketchup, BBQ sauce, and brown sugar glazes are common choices.
What kind of breadcrumbs should I use for meatloaf?
You can use either fresh or dried breadcrumbs. Fresh breadcrumbs will result in a more tender meatloaf, while dried breadcrumbs provide more structure. Panko breadcrumbs are also a popular choice.
Can I make meatloaf ahead of time?
Yes, you can prepare the meatloaf mixture ahead of time and store it in the refrigerator for up to 24 hours before baking. This can actually enhance the flavor. Make sure to bring it to room temperature before baking.
How do I prevent my meatloaf from cracking on top?
While some cracking is normal, you can minimize it by not overmixing the meatloaf mixture and by ensuring the loaf is not overly compact. Cutting a shallow slit along the top before baking can also help.
Can I freeze cooked meatloaf?
Yes, cooked meatloaf freezes well. Allow it to cool completely, then wrap it tightly in plastic wrap and then aluminum foil, or place it in a freezer-safe container. It can be stored in the freezer for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
