How Long to Cook Meatloaf in the Oven

For a standard 2-pound meatloaf, bake at 350°F (175°C) for about 60 to 70 minutes, checking that the center reaches 160°F (71°C) with a food thermometer. This home-style loaf combines ground beef, breadcrumbs, milk, egg, and seasonings; a short rest after baking helps it hold together when sliced.

Ingredients

2 lb (907 g) ground beef, preferably 80% lean
1 cup (60 g) plain panko or fine dry breadcrumbs
1/2 cup (120 ml) milk
1 cup (150 g) finely diced yellow onion
1 large egg (about 50 g without shell)
1/3 cup (80 ml) ketchup, for the meat mixture
1 tbsp (15 ml) Worcestershire sauce
1 tsp (5 ml) Dijon mustard
1 tsp (3 g) garlic powder
1 1/2 tsp (9 g) fine salt
1/2 tsp (1 g) black pepper
1/3 cup (80 ml) ketchup, for the glaze
1 tbsp (12 g) packed brown sugar, for the glaze
1 tsp (5 ml) apple cider vinegar, for the glaze

Instructions

Heat the oven and prepare the pan. Set a rack in the center of the oven and heat it to 350°F (175°C). Line a rimmed baking sheet with foil or parchment. The prep time includes preheating while you mix the ingredients. A rimmed sheet lets hot air circulate around the loaf and allows excess fat to drain; a 9-by-5-inch loaf pan also works, but the sides may keep the loaf sitting in more of its juices.
Soak the breadcrumbs. In a large bowl, stir together the breadcrumbs and milk. Leave them for about 2 minutes, just until the crumbs are moistened. This quick panade helps retain moisture and gives the loaf a tender texture. If the mixture looks dry after the crumbs absorb the milk, add a teaspoon or two of milk; it should be damp, not soupy.
Mix the meatloaf. Add the onion, egg, 1/3 cup (80 ml) ketchup, Worcestershire sauce, Dijon, garlic powder, salt, and pepper. Crumble the ground beef over the top. Use clean hands or a fork to mix gently until the seasonings are distributed. Stop as soon as there are no large pockets of plain meat or breadcrumb mixture; packing or overmixing the beef can make the finished loaf dense.
Shape the loaf. Transfer the mixture to the prepared sheet and shape it into an even loaf about 9 inches (23 cm) long, 5 inches (13 cm) wide, and 2 1/2 inches (6 cm) high. Keep the thickness fairly uniform so the center and ends cook at a similar rate. Avoid pressing it firmly into a compact block. If using a loaf pan, leave a little space at the top and do not pack the mixture tightly.
Make the glaze and bake. Stir together the remaining 1/3 cup (80 ml) ketchup, brown sugar, and cider vinegar. Brush about half over the top of the raw loaf; keep the rest separate for serving or for a fresh finishing layer. Bake for about 65 minutes. Begin checking at 55 minutes, since ovens, pans, and loaf shapes vary. If the top is browning faster than you like, loosely tent it with foil for the remaining bake; do not seal the foil tightly around the loaf.
Check the temperature, then rest. Insert an instant-read food thermometer into the thickest part of the center, approaching from the side if that makes it easier to reach the middle. USDA FSIS guidance sets 160°F (71°C) as the safe minimum internal temperature for ground meat, including ground beef; cook until the center reaches that temperature, even if the outside looks done sooner. If it has not reached 160°F (71°C), return it to the oven and check again after 5 minutes. Rest the cooked loaf for 10 minutes on the baking sheet before slicing. The rest makes cleaner slices, but it does not replace checking the temperature.
Slice and serve. If desired, spread the reserved glaze on the hot loaf after baking. Use a sharp knife to cut it into six thick slices, wiping the blade between cuts if you want especially neat portions. Transfer slices with a wide spatula so they do not break apart.

Tips

Shape matters as much as the clock. A flatter, wider loaf cooks faster than a tall, compact one, and a loaf in a pan may take longer than a free-form loaf on a sheet. Use the stated time as a guide, but let the center temperature decide when it is done.
Choose beef with some fat. Ground beef around 80% lean gives the loaf flavor and helps keep it moist. Very lean beef can turn dry more easily. If you prefer leaner meat, take care not to overmix and begin checking the temperature early.
Keep the mix gentle and the onion small. Finely diced onion softens during baking and is less likely to leave large gaps in a slice. If you want a milder onion texture, sauté it in a teaspoon of oil until soft, then cool it before mixing; allow a few extra minutes for that optional prep.
Adapt the crumbs thoughtfully. Plain fine breadcrumbs work in place of panko in the same volume, though the texture will be a little less light. For a dairy-free version, use unsweetened, unflavored plant milk. Avoid sweetened or strongly flavored substitutes, which can alter the seasoning.

Serving Suggestions

Serve the meatloaf warm with mashed potatoes, roasted potatoes, or buttered noodles to catch the glaze and juices. Green beans, peas, roasted carrots, or a simple green salad add a fresh contrast. For a more substantial plate, add a spoonful of pan juices or extra ketchup glaze and a piece of crusty bread.

For sandwiches, let slices cool enough to stay intact, then tuck them into toasted bread with lettuce, pickles, and a little mustard or ketchup. The loaf is also easy to portion for a family meal: serve one thick slice per person, then offer thinner slices for anyone who wants a smaller serving. If the loaf is very hot, wait until the 10-minute rest is over before slicing so it is less likely to crumble.

Variations

Use a beef-and-pork blend: Replace half the ground beef with 1 lb (454 g) ground pork. The flavor will be richer, and the same safe minimum of 160°F (71°C) applies to this ground-meat mixture. Check the center with a thermometer rather than relying on color.

Make it herb-forward: Add 2 tbsp (8 g) chopped parsley and 1 tsp (1 g) dried thyme, or use 1 tbsp (3 g) chopped fresh thyme. Fresh herbs brighten the flavor; dried herbs taste more concentrated, so use less by volume.

Add a little heat: Stir 1 to 2 tsp (5 to 10 ml) hot sauce or 1/2 tsp (1 g) smoked paprika into the meat mixture. To keep the glaze mild for a mixed table, leave the heat out of the topping and serve hot sauce on the side.

Swap the glaze: Use barbecue sauce instead of ketchup, or mix 1/4 cup (60 ml) ketchup with 1 tbsp (15 ml) maple syrup. These swaps make the top sweeter or smokier, so taste the sauce before brushing it on. Keep the amount similar so the surface is coated without becoming wet.

Storage and Reheating

Refrigerate leftover meatloaf within 2 hours of cooking. Store slices or the remaining loaf in a shallow, airtight container and use within 3 to 4 days. For easier reheating, slice the loaf before chilling; the portions cool and warm more evenly. Keep any fresh glaze separate from raw-meat utensils and store it covered in the refrigerator.

To freeze, wrap cooled slices or portions tightly and place them in a freezer-safe container. For best quality, use within about 2 to 3 months. Thaw frozen portions in the refrigerator, not on the counter. You can also reheat them from frozen, allowing extra time and checking the center temperature.

Warm individual slices in a covered skillet over low heat with a teaspoon of water, or microwave them in short intervals, turning or rearranging as needed. To reheat several slices, place them in a covered baking dish with a splash of water or broth in a 325°F (163°C) oven. Reheat leftovers until they reach 165°F (74°C), checking the center with a food thermometer; the time depends on portion size and whether the meatloaf started chilled or frozen.

Frequently Asked Questions

How long does a 2-pound meatloaf take at 350°F?

A 2-pound loaf usually takes about 60 to 70 minutes at 350°F (175°C), with this recipe using roughly 65 minutes as its estimate. Shape and pan type can shift the timing, so start checking around 55 minutes and remove it only after the center reaches 160°F (71°C).

Should I cover meatloaf while it bakes?

Usually, no. Leaving it uncovered allows the glaze to set and brown. If the top is getting dark before the center is done, lay foil loosely over it for the rest of the baking time. A tight cover can trap steam and make the surface softer.

How can I tell when meatloaf is done without cutting it open?

Use an instant-read thermometer inserted into the thickest part of the center. Ground beef meatloaf is safely cooked when it reaches 160°F (71°C). Color, juices, and the firmness of the top are not dependable substitutes for a temperature reading.

Why does my meatloaf fall apart when I slice it?

It may need more binder, may have been mixed unevenly, or may have been sliced before resting. Measure the breadcrumbs and milk, include the egg, mix until combined, and let the baked loaf rest for 10 minutes. A very hot loaf is more fragile, so use a sharp knife and a wide spatula.

Can I prepare meatloaf ahead of time?

Yes. Shape the uncooked mixture, cover it, and refrigerate it promptly, then bake it within 24 hours. Keep raw meat separate from ready-to-eat foods, and do not leave it at room temperature for more than 2 hours. Because a chilled loaf may need extra oven time, rely on the thermometer and cook its center to 160°F (71°C).
