This panko meatloaf is a classic American-style ground beef loaf, mixed with milk-softened Japanese-style breadcrumbs, onion, egg, and savory seasonings, then finished with a tangy tomato glaze. Panko helps keep the center tender while the glazed top turns glossy and lightly caramelized.
Ingredients
- 1 cup (60 g) plain panko breadcrumbs
- ½ cup (120 ml) whole milk
- 1½ pounds (680 g) ground beef, preferably 80% lean
- 1 small yellow onion, finely grated or minced (about 1 cup / 150 g)
- 1 large egg (about 50 g without shell), lightly beaten
- 2 tablespoons (30 ml) Worcestershire sauce
- 2 tablespoons (30 g) ketchup, for the meat mixture
- 1 teaspoon (5 g) fine salt
- ½ teaspoon (1 g) ground black pepper
- 1 teaspoon (1 g) dried thyme
- ½ teaspoon (1.5 g) garlic powder
- ½ cup (120 g) ketchup, for the glaze
- 1 tablespoon (15 ml) apple cider vinegar
- 1 tablespoon (12 g) packed brown sugar
Instructions
- Heat the oven to 350°F (175°C). Line a rimmed baking sheet with foil or parchment, or lightly oil a 9-by-5-inch (23-by-13-cm) loaf pan. A baking sheet allows more of the sides to brown; a loaf pan keeps the shape contained but may leave the sides softer.
- In a large bowl, stir the panko and milk together. Let stand for 5 minutes, until the crumbs absorb most of the milk. This brief soak helps distribute moisture through the meatloaf rather than leaving dry breadcrumb pockets.
- Add the ground beef, onion, beaten egg, Worcestershire sauce, 2 tablespoons ketchup, salt, pepper, thyme, and garlic powder. Mix gently with clean hands or a fork just until combined. Avoid squeezing or kneading the mixture, which can make the cooked loaf dense.
- Shape the mixture into a loaf about 9 inches (23 cm) long and 4 inches (10 cm) wide on the prepared baking sheet. If using a loaf pan, press it in lightly without packing it down. In a small bowl, mix the remaining ½ cup ketchup with the vinegar and brown sugar. Spread about half the glaze over the top; save the rest for later.
- Bake for 40 minutes. Carefully spoon or brush the remaining glaze over the top, then return the meatloaf to the oven for about 25 to 35 minutes more. Cooking time varies with the loaf’s shape and the oven, so check doneness rather than relying only on the clock. Insert an instant-read food thermometer into the thickest center: the USDA FSIS safe minimum for ground beef is 160°F (71°C). If it has not reached that temperature, continue baking and check again every 5 minutes.
- Once the center reaches 160°F (71°C), transfer the meatloaf to a cutting board and let it rest for 10 minutes before slicing. Resting makes cleaner slices and gives the juices time to settle. Do not leave the meatloaf at room temperature for more than 2 hours total, including serving time.
Tips
- Use the right beef. Ground beef around 80% lean has enough fat for a moist loaf without leaving an excessive amount of grease. Leaner beef can work, but the result may be firmer and less juicy.
- Swap the crumbs carefully. Plain regular breadcrumbs can replace panko in the same volume, though the texture will be slightly less light. For a gluten-free version, use gluten-free panko and check that the Worcestershire sauce is gluten-free.
- Keep mixing gentle. Combine only until there are no obvious streaks of egg or dry crumbs. Overmixing and pressing the loaf tightly are common reasons meatloaf turns compact.
- Use a thermometer, not appearance alone. A browned exterior does not confirm that the center is safely cooked. If the top darkens too quickly before the center reaches 160°F (71°C), loosely tent it with foil while it finishes.
Serving Suggestions
Serve warm slices with mashed potatoes, roasted potatoes, or buttered noodles to catch the tomato glaze. Green beans, peas, roasted carrots, or a crisp green salad add a fresh, simple contrast. For a sandwich, cool a slice slightly and tuck it into toasted bread with extra ketchup or mustard and a few pickle slices.
Variations
For a beef-and-pork loaf, replace up to half of the ground beef with ground pork, keeping the total meat quantity at 1½ pounds (680 g); the texture will be richer, and the center must still reach 160°F (71°C). To add a mild smoky note, stir ½ teaspoon smoked paprika into the meat mixture. You can also replace the thyme with 1 teaspoon dried Italian seasoning. For a less sweet glaze, omit the brown sugar and use ketchup mixed with vinegar and a teaspoon of Dijon mustard.
Storage and Reheating
Refrigerate leftover meatloaf within 2 hours of cooking, in a covered airtight container. It keeps for 3 to 4 days in the refrigerator. Reheat individual slices in the microwave, covered, or in a 325°F (165°C) oven until the center reaches 165°F (74°C), the USDA FSIS temperature for reheated leftovers. Add a spoonful of water or broth before covering if the slices seem dry.
To freeze, wrap cooled slices or portions tightly and freeze for up to 3 months for best quality. Thaw in the refrigerator, then reheat to 165°F (74°C). Avoid reheating the whole loaf repeatedly; warm only the portion you plan to serve.
Frequently Asked Questions
Can I make panko meatloaf ahead?
Yes. Shape the mixture, cover it, and refrigerate it for up to 24 hours before baking. Keep it chilled until it goes into the oven, and check the center temperature; a cold loaf may need extra baking time.
Can I bake it in a loaf pan?
Yes. A 9-by-5-inch (23-by-13-cm) pan works well. The loaf may release liquid and fat into the pan, so carefully drain excess liquid if needed after baking, and use the thermometer reading rather than the pan’s appearance to judge doneness.
Why did my meatloaf fall apart?
It may have needed more binding or resting. Measure the panko and milk accurately, include the egg, and let the finished loaf rest for 10 minutes before slicing. Cutting immediately can make even a properly cooked loaf crumble.
Can I use ground turkey instead of beef?
Yes, but the flavor and texture will be milder and usually leaner. Cook poultry meatloaf to 165°F (74°C), the USDA FSIS safe minimum for ground poultry, checking the thickest part with a food thermometer.
How can I tell if the meatloaf is done without a thermometer?
Color and clear juices are not reliable safety checks for ground meat. Use an instant-read thermometer and confirm the center reaches 160°F (71°C); this is the dependable way to check doneness.
Can I double the recipe?
Yes, but bake the mixture as two separate loaves rather than making one very thick loaf. Separate loaves cook more evenly; begin checking their centers at the recipe’s stated time and continue until each reaches 160°F (71°C).
