How Long to Cook Meatloaf at 400°F

A 2-pound American-style meatloaf usually takes about 50 to 60 minutes to cook at 400°F (204°C), but the reliable doneness check is its center temperature, not the clock. This version combines ground beef, breadcrumbs, milk, and a tangy glaze, then rests briefly so it slices neatly and stays moist.

Ingredients

2 pounds (907 g) ground beef, preferably 80% lean and 20% fat
1/2 cup (30 g) plain panko breadcrumbs
1/3 cup (80 ml) whole milk
1/2 cup (75 g) finely minced yellow onion
1 large egg (about 50 g without the shell), lightly beaten
1 tablespoon (15 ml) Worcestershire sauce
1 teaspoon (5 g) fine salt
1/2 teaspoon (1 g) freshly ground black pepper
1/2 teaspoon (1 g) garlic powder
1/2 cup (120 g) ketchup, divided
1 tablespoon (13 g) packed light brown sugar
1 teaspoon (5 ml) yellow mustard

Instructions

Heat the oven and prepare the pan. Set a rack in the center of the oven and preheat it to 400°F (204°C). Line a rimmed baking sheet with foil or parchment for easier cleanup. A rimmed sheet lets hot air circulate around a free-form loaf and gives rendered fat somewhere to collect. If you prefer a loaf pan, use a 9-by-5-inch (23-by-13-cm) pan and expect the meatloaf to cook toward the longer end of the time range.
Soften the breadcrumbs. In a large bowl, stir the panko and milk together and let them stand for about 2 minutes, while you mince the onion and prepare the glaze. This quick soak helps the crumbs hold moisture and distribute through the beef. Panko gives a slightly lighter texture, while ordinary fine breadcrumbs work too; measure them the same way.
Mix the meatloaf gently. Add the onion, beaten egg, Worcestershire sauce, salt, pepper, garlic powder, and 2 tablespoons (30 g) of the ketchup to the soaked crumbs. Crumble the ground beef over the mixture. Use clean hands or a fork to combine just until you no longer see large pockets of seasoning or dry crumbs. Avoid kneading or compressing the mixture, which can make the cooked loaf dense.
Shape it evenly. Transfer the mixture to the prepared baking sheet and form a loaf about 9 inches (23 cm) long, 5 inches (13 cm) wide, and 2 to 2 1/2 inches (5 to 6 cm) high. Keep the ends and center close to the same thickness so they finish cooking at roughly the same time. Pat the surface lightly; do not pack it down hard.
Make and add the glaze. Stir the remaining ketchup with the brown sugar and mustard in a small bowl. Spread about half the glaze over the top and sides of the shaped loaf. Keep the rest separate for serving or for a final layer. The glaze will darken and become sticky in the hot oven; if it begins to look very dark before the center is done, loosely tent the loaf with foil.
Bake and check the temperature. Bake for about 50 to 60 minutes; begin checking at 45 minutes because loaf thickness, pan material, and oven accuracy affect the timing. Insert an instant-read food thermometer into the thickest center, from the side if that makes it easier to reach the middle. USDA FSIS gives 160°F (71°C) as the safe minimum internal temperature for ground beef, so continue baking until the center reaches at least that temperature. Do not judge doneness by the glaze color or by whether the juices look clear.
Rest, glaze, and slice. Transfer the baking sheet to a heat-safe surface and let the meatloaf rest for 10 minutes. This gives hot juices time to settle and makes the loaf easier to slice without crumbling. Brush on the reserved glaze if you like, then cut into six slices with a sharp knife. If you want to serve the reserved glaze as a sauce, keep it separate from any utensils or plates that touched raw meat.

Tips

Use a thermometer rather than a fixed timer. The 50-to-60-minute estimate fits this 2-pound loaf shaped to an even thickness. A narrow, taller loaf or a cold oven may take longer, while a wider, flatter loaf can cook faster. Check the thickest center, and avoid touching the thermometer tip to the pan or baking sheet.
Keep the mixture tender. The milk-soaked breadcrumbs and egg help the loaf hold together, while the beef’s fat contributes moisture. Mixing only until combined is important: squeezing and working the meat for a long time makes a firmer texture. If the mixture seems unusually wet, let the crumbs absorb it for another minute before shaping rather than adding a large amount of extra crumbs.
Choose substitutions with the texture in mind. Plain fine breadcrumbs can replace panko in the same quantity. For a dairy-free version, use an unsweetened plain plant milk or water; the loaf may be a little less rich. Finely minced onion gives flavor without large pieces, but 1 teaspoon (about 2 g) onion powder can stand in if needed. Worcestershire sauce contains anchovy, so use soy sauce or a suitable vegetarian Worcestershire-style condiment if avoiding fish; the flavor will be somewhat different.
Prevent a greasy or broken loaf. An 80/20 ground beef blend is a useful balance; very lean beef can turn dry, while a high-fat blend may release more grease. Shape the loaf on a rimmed sheet if you want rendered fat to drain away rather than collect around it. Resting before slicing also helps the slices keep their shape.

Serving Suggestions

Serve the meatloaf warm, sliced across the loaf, with the pan glaze or a little extra ketchup on the side. Mashed potatoes, roasted potatoes, buttered noodles, or rice make a filling base for the savory juices. For vegetables, try green beans, peas, glazed carrots, roasted broccoli, or a simple green salad. A sharp or lightly dressed side balances the sweet-tangy topping.

For a relaxed dinner, set the loaf on a platter and let everyone choose a slice and sides. For sandwiches, cool leftover slices enough to handle and tuck them into toasted bread with mustard, pickles, or a little extra ketchup. If the loaf has rested but still releases some juices as you cut it, spoon those over the slices rather than pressing down on the meat.

Variations

Classic herb version: Add 1 tablespoon (about 4 g) chopped fresh parsley and 1/2 teaspoon (about 1 g) dried thyme to the meat mixture. The herbs brighten the beef without changing the method or expected baking time.
Cheddar meatloaf: Fold in 1/2 cup (about 56 g) finely shredded cheddar just before shaping. Keep the cheese pieces small and distributed so the loaf holds together. The cheese adds richness and may leave a few soft pockets inside.
Barbecue-style topping: Replace the ketchup glaze with 1/2 cup (120 g) of your preferred barbecue sauce. Many barbecue sauces contain more sugar than ketchup, so watch the top near the end and tent loosely with foil if it darkens too quickly.
Turkey or pork alternative: Ground turkey or ground pork changes the flavor and moisture of the loaf. For ground turkey, cook to 165°F (74°C), the USDA FSIS safe minimum for poultry. Ground pork should reach 160°F (71°C). In either case, use a thermometer and do not assume the beef timing guarantees the alternative is done; start checking around 45 minutes and continue as needed.

Storage and Reheating

Refrigerate leftover meatloaf within 2 hours of cooking, placing it in a shallow airtight container or wrapping slices securely once they have stopped steaming heavily. Cooked meatloaf keeps for 3 to 4 days in the refrigerator. For easier reheating, store it in individual slices, with any extra glaze in a separate small container.

To reheat a slice in the microwave, cover it loosely and heat in short intervals until steaming hot throughout. In the oven, place slices in a small baking dish with a teaspoon or two of water or broth, cover with foil, and warm at 325°F (163°C). USDA FSIS recommends reheating leftovers to 165°F (74°C); check the center of a thick slice with a food thermometer. Add a little extra glaze after reheating if you want a fresher, saucier finish.

You can freeze cooked meatloaf for longer storage. Wrap individual slices or the cooled loaf tightly, label with the date, and freeze for about 2 to 3 months for best quality. Thaw in the refrigerator, then reheat to 165°F (74°C). Avoid leaving cooked meatloaf at room temperature for more than 2 hours, or more than 1 hour when the room or outdoor temperature is above 90°F (32°C).

Frequently Asked Questions

How long does a 2-pound meatloaf take at 400°F?
A 2-pound loaf shaped about 2 to 2 1/2 inches (5 to 6 cm) high generally takes 50 to 60 minutes at 400°F (204°C). Start checking at 45 minutes, since pan type, loaf shape, and oven calibration can shift the timing. It is done when a thermometer in the center reads at least 160°F (71°C) for ground beef.

Should I cook meatloaf covered or uncovered?
Bake it uncovered so the glaze can set and the surface can brown. If the top becomes dark before the center reaches its safe temperature, loosely cover it with foil for the remaining baking time. Do not seal the foil tightly around the pan, as that traps steam and softens the topping.

Is it better to bake meatloaf in a loaf pan or on a baking sheet?
Both work. A rimmed baking sheet allows hot air to move around the sides and lets rendered fat drain away, while a loaf pan supports a compact shape and contains the juices. A loaf in a pan may take toward the longer end of the range, particularly if it is thick; use temperature, not the pan’s appearance, to confirm doneness.

Why did my meatloaf turn out dry?
Common causes include using very lean beef, overmixing, shaping the loaf too thin, or baking it well beyond 160°F (71°C). Check early with a thermometer, mix only until the ingredients come together, and include the measured milk and breadcrumbs. Letting the loaf rest before slicing also helps keep juices from running out immediately.

Can I prepare the meatloaf ahead of time?
Yes. Shape the uncooked loaf, cover it, and refrigerate it promptly; cook it within 24 hours for best quality. If it goes into the oven cold, it may need extra time, so check the center with a thermometer and do not rely on the usual 50-to-60-minute estimate. Keep raw meat separate from ready-to-eat foods and wash hands and surfaces after handling it.

Can I make this recipe with a different amount of ground beef?
You can scale the ingredients, but baking time does not scale in a simple one-to-one way. A smaller or flatter loaf usually cooks faster, and a larger or thicker loaf usually takes longer. Shape it to an even thickness where possible, begin checking early, and cook ground beef to 160°F (71°C) in the center.
