How Long to Cook Meatloaf at 375°F? A Reliable Guide

At 375°F (190°C), a free-form 2-pound (900 g) meatloaf usually takes about 55 to 65 minutes to bake, but its internal temperature—not the clock—is the dependable doneness check. This beef meatloaf combines breadcrumbs, milk, egg, and seasonings for a tender slice, with a simple ketchup glaze that turns glossy in the oven.

Ingredients

2 lb (900 g) ground beef, preferably 85% to 90% lean
3/4 cup (45 g) plain dry breadcrumbs
1/3 cup (80 ml) milk
1 large egg (about 50 g without the shell)
1/2 cup (75 g) finely diced yellow onion
2 cloves garlic, finely minced (about 6 g)
2 tablespoons (30 ml) ketchup, for the meat mixture
1 tablespoon (15 ml) Worcestershire sauce
1 teaspoon (5 g) fine salt
1/2 teaspoon (1 g) ground black pepper
1 teaspoon (1 g) dried thyme
1/2 cup (120 ml) ketchup, for the glaze
1 tablespoon (15 ml) packed brown sugar
1 teaspoon (5 ml) apple cider vinegar

Instructions

Heat the oven and prepare a pan. Set a rack in the middle of the oven and heat it to 375°F (190°C). Line a rimmed baking sheet with foil or parchment for easier cleanup. A rimmed sheet lets a free-form loaf brown on its sides and allows excess fat to drain away; do not use a flat, unrimmed tray.
Soften the breadcrumbs. In a large bowl, stir together the breadcrumbs and milk. Let them stand for about 3 minutes, while you dice the onion and mince the garlic. The crumbs should look damp and swollen rather than dry. This brief soak helps distribute moisture through the meat and makes the finished loaf less dense.
Mix the meatloaf gently. Add the egg, onion, garlic, 2 tablespoons ketchup, Worcestershire sauce, salt, pepper, and thyme to the breadcrumb mixture. Stir to combine, then add the ground beef. Use clean hands or a fork to mix just until the ingredients are evenly distributed. Avoid squeezing or kneading the mixture; overmixing can make a meatloaf tight and chewy.
Shape the loaf. Transfer the mixture to the prepared sheet and shape it into a compact loaf about 9 inches (23 cm) long, 5 inches (13 cm) wide, and 2 to 2 1/2 inches (5 to 6 cm) high. Aim for an even thickness so the ends do not dry out before the center is cooked. Smooth cracks along the surface with damp fingers.
Make the glaze. In a small bowl, stir together the remaining 1/2 cup ketchup, brown sugar, and cider vinegar. Spread about half of this mixture over the top and sides of the loaf, reserving the rest for serving. The sugar encourages browning, so keep the meatloaf on the middle rack rather than close to the heating element.
Bake and check the center. Bake for about 55 to 65 minutes. Start checking at 50 minutes, since loaf thickness, pan material, and oven accuracy affect the timing. Insert an instant-read thermometer into the thickest center section without touching the pan. The USDA FSIS safe minimum internal temperature for ground meat is 160°F (71°C); cook the meatloaf until the center reaches that temperature. If it has not reached 160°F, continue baking and check again every 5 minutes.
Rest, slice, and serve. Remove the meatloaf from the oven and let it rest on the sheet for 10 minutes. Resting helps the loaf hold together when sliced, but it does not replace the thermometer check. Slice with a sharp knife and serve with the reserved glaze. If you prefer a stickier top, spoon the glaze over the slices rather than returning the loaf to the oven.

Tips

Choose the right beef. Ground beef around 85% to 90% lean gives the loaf enough fat for flavor without leaving as much grease as a fattier blend. Very lean beef can still work, but the texture may be drier; take care not to overmix and check the temperature as soon as the expected bake time approaches.
Keep the shape even. A loaf with a thick middle and thin ends cooks unevenly. Shape it to a consistent height, and use the center temperature to decide when it is done. A thermometer is more reliable than judging by browned color, clear juices, or a set-looking glaze.
Make the onion small. Finely diced onion softens during baking and blends into each slice. Large pieces can remain crunchy or cause the meatloaf to crumble around them. If you want a softer onion flavor, briefly cook the diced onion in a little oil, then cool it before adding it to the meat mixture.
Adjust the binder thoughtfully. If the mixture seems unusually wet, add breadcrumbs one tablespoon (about 7 g) at a time rather than adding a large handful. If you do not have Worcestershire sauce, use an equal amount of soy sauce; it brings a similar savory note but is saltier, so you may want to reduce the added salt slightly.

Serving Suggestions

Serve the meatloaf hot, cut into slices about 3/4 inch (2 cm) thick, with mashed potatoes or roasted potatoes to catch the glaze and juices. Green beans, peas, glazed carrots, roasted broccoli, or a crisp green salad add a fresh contrast to the savory beef. For a simple plate, add a spoonful of the reserved ketchup glaze and a vegetable; for a more substantial dinner, include buttered noodles or dinner rolls.

Leftover slices also make satisfying sandwiches. Put cold or gently reheated meatloaf on sturdy bread with lettuce, sliced tomato, and a little mustard, or warm a slice and place it in a toasted bun. Keep extra glaze on the side so each person can add as much as they like without making the bread soggy.

Variations

Use a beef-and-pork blend: Replace half the ground beef with 1 lb (450 g) ground pork. Keep the same cooking method and use a thermometer to confirm the center reaches 160°F (71°C), the safe minimum for this ground-meat mixture. The pork makes the flavor richer and the texture somewhat softer.

Make it with ground turkey: Substitute 2 lb (900 g) ground turkey for the beef. Ground turkey must reach 165°F (74°C), the USDA FSIS safe minimum for poultry, so check the center with a food thermometer and expect the bake time to vary. Because turkey is lean, avoid overbaking once it reaches the required temperature.

Change the glaze: Replace the brown sugar with 1 tablespoon (15 ml) maple syrup, or stir 1 teaspoon (5 g) Dijon mustard into the ketchup mixture for a tangier finish. For a less sweet top, omit the sugar and use ketchup with a splash of vinegar. Glaze ingredients change the flavor and browning, not the meatloaf’s safe internal temperature.

Add a gentle heat: Stir 1/4 teaspoon (1 g) smoked paprika or a pinch of red pepper flakes into the meat mixture. For a vegetable-forward version, add up to 1/2 cup (75 g) finely grated carrot, squeezing out excess liquid first. Too much wet vegetable can soften the loaf and make it harder to slice neatly.

Storage and Reheating

Refrigerate cooked meatloaf within 2 hours of baking. Once it has cooled enough to handle, store it in an airtight container or wrap it well; it keeps for 3 to 4 days in the refrigerator. For easier reheating, store individual slices separately. Keep any leftover glaze in a clean, covered container in the refrigerator as well.

To freeze, wrap the cooled loaf or individual slices tightly, then place them in a freezer-safe container or bag. For best texture, use frozen meatloaf within about 2 to 3 months. Thaw it overnight in the refrigerator rather than on the counter. You can also reheat slices from frozen, allowing extra time and checking the center.

Reheat leftovers in a covered oven-safe dish at 325°F (165°C), with a spoonful of water or extra glaze to reduce drying, until the center reaches 165°F (74°C). A microwave also works: cover a slice, heat it in short intervals, and check the center with a thermometer. The USDA FSIS recommends reheating leftovers to 165°F (74°C); do not rely only on a warm surface or steaming sauce.

Frequently Asked Questions

How long does a 2-pound meatloaf take at 375°F?

A 2-pound (900 g) free-form meatloaf usually takes about 55 to 65 minutes at 375°F (190°C). Begin checking at 50 minutes, because a thicker loaf or an oven that runs cool may need longer. It is ready when a thermometer in the center reads 160°F (71°C) for ground beef.

Should I cover meatloaf while it bakes?

For this free-form recipe, leave the meatloaf uncovered so the glaze can set and the sides can brown. If the top becomes too dark before the center reaches its safe temperature, loosely tent it with foil for the rest of the baking time. Do not let foil touch or pull off the glaze when you remove it.

Is it better to bake meatloaf in a loaf pan or on a sheet?

A rimmed baking sheet is useful for a free-form loaf because air reaches the sides and grease can drain away. A loaf pan works too, but the meatloaf may sit in rendered fat and its sides will not brown as much. If using a pan, do not assume the same timing will apply; check the center temperature and allow for a possible longer bake.

Why did my meatloaf fall apart when sliced?

Common causes include too little binder, a mixture that was not evenly combined, or slicing immediately after baking. The egg and soaked breadcrumbs help hold this recipe together, while a 10-minute rest lets the slices firm up. If the mixture is very loose before baking, mix in a little extra breadcrumb, but do not pack the meat tightly.

Can I prepare meatloaf ahead of time?

Yes. Shape the raw loaf, cover it, and refrigerate it for up to 24 hours before baking. Keep it chilled until it goes into the oven, and do not count refrigerator time as baking time. A cold loaf may take longer than the stated range, so use the thermometer reading of 160°F (71°C) at the center to confirm doneness.
