How Long to Cook a Half-Pound Meatloaf?

A half-pound meatloaf is a small, tender loaf of seasoned ground beef held together with breadcrumbs, milk, and egg, then finished with a simple ketchup glaze. It usually needs 35 to 45 minutes in a 350°F (177°C) oven; the thermometer, not the clock, tells you when it is safely done.

Ingredients

8 oz (227 g) ground beef, preferably 85% lean
1/4 cup (25 g) fine dry breadcrumbs
2 tablespoons (30 ml) milk
1/4 cup (about 40 g) finely diced onion
1 tablespoon (15 g) beaten egg, measured after beating
1 tablespoon (15 g) ketchup, for the meat mixture
1/2 teaspoon (2.5 ml) Worcestershire sauce
1/4 teaspoon (1.5 g) fine salt
1/8 teaspoon (about 0.3 g) black pepper
1 tablespoon (15 g) ketchup, for the glaze
1 teaspoon (4 g) brown sugar, for the glaze (optional)

Instructions

Heat the oven to 350°F (177°C). Line a small rimmed baking sheet or oven-safe dish with foil or parchment for easier cleanup. If using foil, lightly oil the area where the loaf will sit. A loaf pan is not necessary; shaping the meat on a baking sheet leaves more surface exposed so the glaze can set and excess fat can drain away.
In a small bowl, stir the breadcrumbs and milk together and let them sit for about 2 minutes, until the crumbs are damp. This quick soak helps the binder distribute evenly instead of drawing moisture from the beef. Meanwhile, measure the beaten egg: crack and beat one egg, then use 1 tablespoon for the recipe. Refrigerate the remaining egg promptly for another use.
Add the diced onion, measured egg, 1 tablespoon ketchup, Worcestershire sauce, salt, and pepper to the breadcrumb mixture. Stir to combine. Add the ground beef and mix gently with clean hands or a fork just until everything is evenly distributed. Stop as soon as the mixture holds together; squeezing or kneading it for a long time can make the finished loaf firm and dense.
Transfer the mixture to the prepared pan and shape it into a compact loaf about 4 inches (10 cm) long, 2 inches (5 cm) wide, and 1 1/2 inches (4 cm) high. Keep the thickness fairly even so the center and ends cook at a similar rate. In a small bowl, combine the glaze ketchup with the brown sugar, if using, and spread it over the top.
Bake for about 35 to 45 minutes. Start checking at 35 minutes, since loaf dimensions, pan material, and oven accuracy affect the timing. Insert an instant-read food thermometer into the center from the side or top without touching the pan. The USDA FSIS safe minimum temperature for ground beef is 160°F (71°C); remove the meatloaf when its center reaches that temperature, even if the clock estimate has not elapsed.
Rest the meatloaf on the pan for 10 minutes before slicing. The rest allows the juices to settle and makes a small loaf less likely to crumble when cut. The recipe’s estimated 50-minute cook time includes about 40 minutes in the oven and this 10-minute rest; actual oven time can be shorter or longer, so use the thermometer reading as the doneness test.

Tips

Keep the loaf compact but not packed. A loaf that is too tall takes longer to heat through, while a very thin one can dry out before the glaze sets. Shape it evenly and avoid pressing the mixture tightly into a dense block.
Adjust the binder if needed. Fine dry breadcrumbs work well, but plain panko can also be used in the same volume; the texture may be a little more open. If using fresh breadcrumbs, use about 1/3 cup (35 g), since they are less compact. The milk softens either type, so do not add extra crumbs just because the mixture feels moist.
Use lean, not ultra-lean, beef. Ground beef around 85% lean gives the small loaf enough fat for a juicy texture without leaving a large pool of grease. If you use 90% lean beef, check it near the early end of the time range and avoid extending the bake after it reaches 160°F (71°C).
Do not judge by color or juices alone. Ground beef can look brown before reaching a safe temperature, and color is not a reliable doneness check. Clean the thermometer probe after it touches raw meat, and wash hands and utensils that handled the uncooked mixture before they touch cooked food.

Serving Suggestions

Slice the rested loaf into two generous portions, or cut it into smaller slices if serving it with several sides. Mashed potatoes, roasted potatoes, buttered noodles, or rice make easy partners for the ketchup glaze. Add a green vegetable such as green beans, peas, broccoli, or a crisp salad to balance the plate. A spoonful of pan juices can be served over the slices, but discard any liquid that has contacted raw meat before cooking.

For a small family-style meal, put the loaf on a warm platter and serve the remaining glaze at the table. If you are making the recipe for one person, the second portion keeps well for lunch the next day. Leftover slices also work in a sandwich: place them in a toasted roll with lettuce, pickles, or a little mustard after reheating them safely.

Variations

Use ground turkey. Replace the beef with 8 oz (227 g) ground turkey. The texture and flavor will be milder, and lean turkey can dry out more quickly, so check the center early. Ground poultry must reach 165°F (74°C), the USDA FSIS safe minimum, rather than the 160°F (71°C) target for ground beef.

Make it without Worcestershire sauce. Leave it out or replace it with 1/2 teaspoon (2.5 ml) soy sauce. Soy sauce adds a saltier, less tangy flavor, so you can reduce the added salt slightly if you prefer. If avoiding soy, a small splash of vinegar mixed with a pinch of sugar adds some tang, though it will not have the same savory depth.

Add herbs or vegetables. Stir in 1 teaspoon (1 g) chopped fresh parsley or 1/4 teaspoon (about 0.3 g) dried thyme. For extra vegetables, finely grate up to 2 tablespoons (about 15 g) of carrot and squeeze out excess moisture before mixing it in. Larger or wetter additions can make this half-pound loaf loose and extend its cooking time.

Change the topping. The brown sugar is optional; ketchup alone gives a less sweet glaze. You can replace the ketchup with 1 tablespoon (15 g) barbecue sauce for a smoky, sweeter finish, but check its label because some sauces are saltier than ketchup. Spread a thin layer rather than a thick coating so the center can finish cooking before the topping becomes overly dark.

Storage and Reheating

Refrigerate cooked meatloaf within 2 hours of cooking, preferably in a shallow, covered container. Keep it refrigerated at 40°F (4°C) or colder and use it within 3 to 4 days. For the best texture, store the loaf whole or in thick slices with any glaze or juices; tightly cover it to limit drying and to keep it from picking up odors from other foods.

To freeze, wrap cooled portions tightly and place them in a freezer-safe container or bag. For best quality, use within about 2 to 3 months. Thaw frozen meatloaf in the refrigerator, not on the counter, and use thawed leftovers within 3 to 4 days. You can also reheat a frozen portion directly, but it will take longer and should be checked in the center.

Reheat individual slices covered in a microwave-safe dish, or warm them covered in a 325°F (163°C) oven with a teaspoon of water or broth to reduce drying. Heat leftovers until the center reaches 165°F (74°C), the USDA FSIS safe temperature for reheated leftovers. Check with a food thermometer, especially when reheating a thick piece; a warm surface does not mean the middle is hot enough.

Frequently Asked Questions

Is 30 minutes enough to cook a half-pound meatloaf?
A small, flat loaf might approach doneness in 30 minutes, but that is not a dependable cooking time. Start checking at 35 minutes for the shape in this recipe, then continue until the center reaches 160°F (71°C). A thicker loaf, a cold starting mixture, or an oven that runs cool can take longer.

Should I cover the meatloaf while it bakes?
No cover is needed for this small loaf. Baking it uncovered helps the glaze set and lets the outside brown. If the top is getting too dark before the center reaches its safe temperature, lay a small piece of foil loosely over the top and continue baking; do not use the browning of the glaze as a substitute for checking the center.

Can I bake the mixture in a small loaf pan?
Yes. A small oven-safe pan can hold the mixture, but the loaf may cook a little more slowly because the sides are enclosed and rendered fat stays around it. Avoid filling a large loaf pan with this small amount, since the mixture will spread into a thin layer. Check the center with a thermometer and allow extra time if it has not reached 160°F (71°C).

Can I prepare the meatloaf ahead?
You can shape it, cover it, and refrigerate it for up to 24 hours before baking. Keep raw ground beef cold and bake it directly from the refrigerator, allowing for a few extra minutes if needed. Apply the glaze just before baking for the neatest finish, and always verify that the center reaches 160°F (71°C).

Can I cook a half-pound meatloaf from frozen?
For more even cooking, thaw it in the refrigerator before baking rather than putting a frozen loaf straight into the oven. A frozen center makes the outside cook much sooner than the middle, so the usual 35-to-45-minute estimate does not apply. Once thawed, bake as directed and use a thermometer to confirm the safe temperature.

Why did my small meatloaf crumble when sliced?
Common causes include too little binder, uneven mixing, cutting before the rest, or slicing very thinly. Measure the egg and breadcrumbs, mix only until combined, and give the loaf the full 10-minute rest. A serrated or sharp knife and slightly thicker slices also help a small loaf hold its shape.
