How Long to Cook Meatloaf at 350 and 375
Bake a 2-pound meatloaf at 350°F (177°C) for about 55–70 minutes or at 375°F (191°C) for about 45–60 minutes. Take it from the oven only when the centre reaches 160°F (71°C). A meatloaf is ground meat, so its safety endpoint differs from a whole pork chop or roast.
How long to cook meatloaf at 350 and 375
| Pan and loaf size | 350°F / 177°C | 375°F / 191°C | Temperature target |
|---|---|---|---|
| 1 pound, shallow free-form | 35–50 minutes | 30–40 minutes | 160°F / 71°C |
| 2 pounds, loaf pan | 55–70 minutes | 45–60 minutes | 160°F / 71°C |
| 3 pounds, deep loaf pan | 75–95 minutes | 65–80 minutes | 160°F / 71°C |
The USDA Food Safety and Inspection Service identifies 160°F (71°C) as the minimum internal temperature for ground beef, pork, veal, and lamb. A timer helps plan a meal; it cannot see a cool centre inside a dense loaf. Measure at the centre of the thickest section, not at the surface and not in a pool of rendered juices.
Why pan shape matters more than weight
Meatloaf is a mixture of ground meat and binders shaped into a loaf. A broad, shallow 2-pound loaf has more exposed area and can finish much earlier than the same mass packed into a narrow 9-by-5-inch pan. The depth from top to centre is what delays the reading. A loaf pan also traps liquid around the sides, while a free-form loaf lets more fat drain away. Neither form is automatically better; they require different checks.
Use an instant-read thermometer after the lower end of the range. Insert the probe horizontally until its tip sits in the geometric centre. If the reading is 150°F (66°C), return the loaf for 5 minutes and check again. If the reading is 160°F (71°C), remove it. A brown glaze or firm-looking crust says little about the temperature of the middle.
Worked example: a 2-pound loaf in a metal pan
A loaf made from 907 grams of ground beef and pork, egg, crumbs, and vegetables was packed 7 centimetres deep in a metal pan. At 350°F (177°C), its centre was 145°F (63°C) after 50 minutes, 156°F (69°C) after 60 minutes, and 161°F (72°C) after 65 minutes. The loaf rested for 10 minutes before slicing. The numbers show a method: the first check exposed the actual rate of heating; they do not guarantee that a different pan or mixture will need 65 minutes.
| Result | What it suggests | Practical response |
|---|---|---|
| Surface dark, centre below 150°F | Exterior is ahead of interior | Loosely shield top and continue |
| Centre 160°F, juices present | Ground meat endpoint reached | Rest before slicing |
| Centre 170°F or higher | Likely overcooked texture | Shorten next batch’s first check |
How to prevent dry or crumbly meatloaf
Mix only until ingredients are combined. Overmixing compacts the proteins and can make the finished slice tight. Keep the loaf evenly shaped, leave room around a free-form loaf, and do not compress a pan loaf beyond what makes it hold together. A glaze applied near the end limits burning; a sugary glaze at the start can darken long before the centre is cooked. Let the finished loaf stand at least 10 minutes so slices hold their shape.
Do not use a fork to make repeated doneness tests. Each puncture releases juices and still provides no exact internal measurement. One or two thermometer checks in the centre are more useful than cutting the loaf open. Wash the probe between raw and cooked use.
Common meatloaf timing mistakes
- Using a whole-cut meat temperature for ground meat. Ground meat needs 160°F (71°C), not 145°F.
- Assuming every 2-pound loaf has the same depth.
- Starting with a cold glass dish and expecting a metal-pan timetable to match.
- Putting vegetables in large wet pieces that create a loose, uneven centre.
- Slicing immediately, which makes a safe loaf appear wetter and fall apart.
Limits of this meatloaf guide
A stuffed loaf, a loaf made from raw poultry, and individual mini loaves need separate measurements. Ground poultry must reach 165°F (74°C) according to the same USDA chart. A convection oven can colour the top sooner than a conventional oven. If the recipe includes a cheese-filled centre, check both the meat surrounding it and the filling’s heat according to the recipe. Never use a time range to rescue a loaf that began partly frozen.
For another ground-food temperature context, the Food Safety and Inspection Service’s safe-temperature chart is the named source for the 160°F (71°C) endpoint. For an oven comparison with whole poultry, see how long to bake chicken breast. The two pages share an oven but not an internal temperature rule.
A dependable final check
Set a timer at 45 minutes for a 2-pound pan loaf at 350°F. Measure the centre, then use 5-minute intervals while the reading is below 155°F (68°C), switching to 2- or 3-minute intervals as it approaches 160°F (71°C). Rest the loaf on a clean board or in the pan, note the depth and final time, and use that record for the next batch. This gives a direct answer quickly without pretending that all pans, blends, and ovens heat alike.
Extra checks for meatloaf
Meatloaf contains ground meat, so the centre must be measured rather than inferred from crust colour. Ground meat has been mixed throughout, which is why the USDA Food Safety and Inspection Service specifies 160°F (71°C) for ground beef, pork, veal, and lamb.
A free-form loaf is usually shallower than a loaf-pan version. If you change from one shape to the other, reset the first check instead of relying on a previous total time. The depth of the centre is the important measurement.
Let a verified loaf rest before slicing. Resting improves slice structure, but it cannot compensate for a centre that was removed below 160°F (71°C). Keep raw-meat tools separate from the plate used for the finished loaf.
If a glaze darkens early, shield it loosely while the centre continues cooking. Do not raise the oven setting just to hurry a cold middle; that often burns the outside before the temperature problem is resolved.
Make the final decision with a direct check, then note the result for the next meatloaf batch. A measured endpoint, a stated temperature in degrees Fahrenheit and Celsius where relevant, and the largest piece’s size give a reader information that can be repeated. This is more dependable than extending the timer by habit when the tray, oven, or food size has changed.

Final measurement note
Before serving, make one final check on the largest portion and write down the result. Keep the oven setting, pan, thickness, and total minutes together in one note. That record is specific to this food and equipment. It prevents a later cook from confusing a useful range with an automatic promise, and it makes small adjustments safer and easier to explain.
