Note: The cooking times listed above are approximate and assume that the internal temperature of the meatloaf is 160 degrees F when fully cooked.
A lot of people ask how long it takes to cook a meatloaf, but the answer is: it depends.
It depends on your cooking temperature and equipment.
For example, I recently cooked a 1-pound meatloaf in my convection oven at 350 degrees Fahrenheit for about an hour.
But if you’re using a regular oven, it will probably take about 10 minutes longer than that.
It also depends on your experience with cooking.
If you’ve made meatloaf before and feel comfortable with it, you might know that the outside starts to feel firm at the 45-minute mark, or when the internal temperature measured by a meat thermometer reaches 160 degrees Fahrenheit.
If this is your first time making meatloaf, though, you might want to set a timer for an hour or so and check it periodically until you’re confident about how long it takes to cook in your own oven at your particular temperature setting.
How Long Does It Take to Cook a 1 Pound Meatloaf at 300?
It should take 45 to 55 minutes to cook a 1 pound meatloaf at 300°F to reach an internal temperature of 160°F. Use a probe thermometer inserted into the center of the meatloaf to check the internal temperature in multiple places, and take it out of the oven when it reaches 160°F.
Here are some tips on cooking a 1 pound meatloaf at 300 degrees:
- Be careful to avoid over-mixing the meatloaf. This makes it dense and tough.
- Add some cooked, crumbled bacon to the meat mixture to make it extra savory! Bacon makes everything better, after all.
- You can also use your favorite spices to give the meatloaf a custom flavor. For example, we love adding garlic powder, dried onion flakes, and dried parsley flakes. We keep these in a little bowl by the stove so they’re always ready to go when we need them!
How Long Does It Take to Cook a 1 Pound Meatloaf at 325?
You can expect to cook your 1 pound meatloaf at 325°F for 40 minutes to 45 minutes, depending on your oven, to reach an internal temperature of 160°F. This can be measured precisely with a digital probe thermometer.
When you’re cooking a 1 pound meatloaf at 325°F, here are some tips and tricks to keep in mind:
- Measure the temperature of your oven. If it’s not calibrated properly, you could end up undercooking or overcooking your meatloaf.
- Make sure to use a digital probe thermometer. It will give you an accurate reading of the internal temperature of your meatloaf, ensuring it’s cooked all the way through but not over-cooked.
- Cook your meatloaf on a wire rack that fits in a roasting pan, so that heat can circulate around the entire loaf and cook it evenly. If you don’t have a wire rack, and still want to use a roasting pan, you can place balls or crumpled pieces of aluminum foil in the bottom to raise the loaf up off the pan.
How Long Does It Take to Cook a 1 Pound Meatloaf at 350?
A 1-pound meatloaf will take 30 to 35 minutes to cook in a 350°F oven. To determine if your meatloaf is done, use a meat thermometer to measure the internal temperature of the loaf. Once it reaches 160°F, you can safely remove it from the oven.
First and foremost, your oven temperature can vary quite a bit from what it says on the dial.
You might think it’s 350°F when it’s really 100 degrees less, or vice versa. So if you haven’t before, invest in an oven thermometer to make sure you’re cooking at the right temperature.
Second, the internal temperature of your meatloaf is what determines when it’s done.
The outside of the loaf may look great and golden brown, but if it hasn’t reached 160°F inside, it needs more time in the oven. Use a meat thermometer to be sure!
How Long Does It Take to Cook a 1 Pound Meatloaf at 375?
It takes about 30 minutes to cook a 1-pound meatloaf at 375°F. To make sure the loaf is cooked, insert a meat thermometer in the middle of the loaf. The loaf will be done when it reaches an internal temperature of 160°F.
Here are some extra tips to keep in mind when cooking meatloaf at 375:
- Use 80/20 ground beef. This means that there are 20% fat and 80% lean beef. Fat gives the final product flavor, while lean beef makes the loaf more dense.
- Don’t overmix! Overmixing can cause your meatloaf to turn out tough. Our tip is to use a spoon or spatula instead of your hands so you won’t overmix everything together.
- Get creative with your ingredients! Add shredded cheese for an extra cheesy meatloaf or try adding chopped up bacon for a more flavorful dish.

How Long Does It Take to Cook a 1 Pound Meatloaf at 400?
You can expect to cook a 1 pound meatloaf at 400°F for about 40 minutes. However, the final cooking time will depend on the shape of your loaf; thinner loaves will cook faster than thicker ones.
To make sure your meatloaf is cooked through, you’ll want to take an internal temperature reading with a probe thermometer. Your meatloaf is ready when the internal temperature reaches 160°F.
Now that you’re cooking your meatloaf at 400°F, here’s a few other tips and tricks for the best possible meatloaf-making experience:
- If you’re using a convection oven, you may want to reduce the oven temperature by 25°F. Because the air is constantly circulating, convection ovens cook hotter and faster than conventional ovens do.
- Make sure to let your meatloaf rest for at least 5 minutes before slicing into it. This is important; letting it rest allows the juices in your meatloaf to redistribute throughout the loaf so they don’t all run out when you cut into it.
- Be sure to let your meatloaf cool completely before storing leftovers in the fridge or freezer. The safest way to go here is to wait at least 2 hours before refrigerating or freezing your leftovers—and please, don’t leave them out for longer than 2 hours!
How Long Does It Take to Cook a 1 Pound Meatloaf at 425?
It takes about 30 minutes per pound to cook a 1 pound meatloaf at 425 degrees Fahrenheit. You’ll know the meatloaf is finished when the internal temperature has reached 160°F and the edges are crispy, or you can use a probe thermometer to check the internal temperature.
When it comes to cooking meatloaf at 425°F, here are some tips and tricks that I’ve learned the hard way:
- Make sure the meatloaf is fully thawed before you put it in the oven. If it’s still cold or frozen in the middle, it will cook unevenly, which could mean that parts of your meatloaf will be overcooked while other parts are still raw or undercooked.
- If you’re using a meat thermometer, remember that the probe shouldn’t touch any bone when you’re checking the internal temperature of your meatloaf. Otherwise, you’ll get an inaccurate reading and may end up taking the meatloaf out of the oven too early or leaving it in too long.
- Use different ingredients and spices than your usual go-to’s to keep things interesting and help avoid getting bored with eating leftovers over and over again!
How Long Does It Take to Cook a 1 Pound Meatloaf at 450?
A 1-pound meatloaf should take 15-25 minutes to cook at 450°F. You will know it’s ready when the internal temperature is 160°F. Use a probe thermometer to make sure you’re getting an accurate reading.
Here’s some extra tips and tricks:
- Place the meatloaf on a wire rack over a baking tray for even heating throughout the loaf. If you don’t have a rack, flip the loaf half way through cooking.
- Don’t slice into your meatloaf right away, let it rest for 10 minutes before serving.
- Add a cup of diced onions, celery and carrots to your meatloaf mixture for added flavor.
- Add cheese in the middle of your loaf to add an additional flavor boost!
6 Tips for Cooking a 1 Pound Meatloaf at Any Temperature
If you’ve never cooked a meatloaf before, the first step is to not panic!
Meatloaf is an incredibly versatile dish.
There are many different ways you can make it, and it’s hard to mess up.
You can use different meats, spices, or even vegetables to make your meatloaf unique.
Here are six tips for cooking meatloaf at any temperature:
1. Cooking at A Low Temperature? Use a Covered Pan!
When you’re cooking a 1-pound meatloaf at a low temperature, it’s important to make sure the pan is covered so your meatloaf doesn’t dry out.
That’s because the heat is lower and this forces the meat to retain more moisture.
If you cook the meatloaf in an uncovered pan, the juices from the meat will escape through evaporation and leave it dry and tough by the time it’s cooked through.
You can tell if your meatloaf is not cooked in a covered pan if it starts to shrink down as it cooks.
This means that all of its juices are escaping and you need to cover it up with aluminum foil for the rest of the cooking time.
Cooking your meatloaf in a covered pan also keeps your oven cleaner—no splatters!
2. Roasting Rack
If you’re using ground beef that’s 85% lean or less, be sure to use a roasting rack so the fat drips off during cooking.
This will help ensure your meatloaf doesn’t have an excessive amount of grease, and will also help avoid burning your meatloaf if you’re cooking it at a higher temperature for less time.
3. Avoid Dry Meat
A rack is a great tool for keeping your ground beef moist and juicy when cooking a meatloaf at any temperature.
For ground beef that’s 90% lean or more, try placing the meatloaf on a rack in a shallow roasting pan and covering it with foil, so it doesn’t dry out.
This method also works if you don’t have time to cook your meatloaf at lower temperatures.
The rack will let the heat circulate around the meatloaf and ensure that it cooks evenly—just make sure you allow enough cooking time (at least an hour) for it to fully cook through.
4. Use a Meat Thermometer
Meatloaves can be tricky. It’s really easy to overcook them, but they’re also difficult to get just right.
When you’re taking your meatloaf out of the oven, you might think it looks great and then as soon as you cut into it, realize that it’s undercooked or overcooked!
The best way to make sure that your meatloaf is cooked correctly is to use a meat thermometer.
This will help you accurately determine the internal temperature of your meatloaf and make sure that you don’t eat it before it’s fully cooked.
You want your meatloaf to reach an internal temperature of 160F before eating, so wait until the thermometer registers 160F before serving.
5. The Poke Test
If you don’t have a meat thermometer, try the “poke test.” Press down on the top of the loaves with a fork or spatula. If the juices run clear, your loaf is done!
You can also try the “bounce test”. Gently hold one end of the loaf and let it bounce. If it bounces back quickly, then it needs to cook longer. If it bounces slowly, then that means that it’s about ready to be taken out of the oven.
No matter which method you choose, remove your meatloaf from the oven at least ten minutes before serving.
This will allow time for the loaf to absorb any remaining liquid and ensure that your meatloaf has that melt-in-your-mouth texture!
6. Don’t Overcook Your Meatloaf
Meatloaf is one of those foods that’s often derided as bland, boring, or just plain bad. But we all know full well that it can be delicious—and it’s so easy to make! The key is to not overcook it.
Once you reach 160F, take it out immediately and let it rest for 5-10 minutes before serving.
You should also always use a thermometer to check the temperature of your meatloaf.
Even if you think you’re an expert meatloaf-maker and don’t need one—you do.
So many people ruin their meatloaves by relying on visual cues or cooking times instead of temperature. Don’t be one of them!
You’ll know when your meatloaf is done because you’ll have used a thermometer to check the temperature and verify that it has reached 160F degrees, then taken the meatloaf out of the oven and let it rest for five to ten minutes before serving.
It will probably smell delicious, too—but resist the temptation to dive in before letting it cool down a little bit.
