A 1-pound (454 g) meatloaf takes about 14–16 minutes to cook in a 1,000-watt microwave, followed by a 5-minute rest. Made with ground beef, breadcrumbs, egg, and seasonings, this quick version is shaped into a ring so it cooks more evenly than a thick, solid loaf.
Ingredients
- 1 pound (454 g) lean ground beef, preferably 85–90% lean
- 1/2 cup (55 g) plain breadcrumbs
- 1/4 cup (60 ml) milk
- 1 large egg (about 50 g without the shell)
- 1/3 cup (50 g) finely chopped onion
- 2 tablespoons (30 ml) ketchup, plus 2 tablespoons (30 ml) for the topping
- 1 teaspoon (5 ml) Worcestershire sauce
- 3/4 teaspoon (4.5 g) fine salt
- 1/4 teaspoon (0.5 g) ground black pepper
- 1/2 teaspoon (1.5 g) garlic powder
Instructions
- Prepare the mixture. In a large bowl, stir together the breadcrumbs and milk and let them stand for 2 minutes. This gives the crumbs time to absorb the liquid and helps keep the cooked meatloaf from turning dry or crumbly. Add the egg, chopped onion, 2 tablespoons ketchup, Worcestershire sauce, salt, pepper, and garlic powder. Mix briefly, then add the ground beef.
- Combine without compacting. Use clean hands or a fork to mix just until the seasonings and breadcrumb mixture are distributed. Avoid squeezing or kneading the beef; packing it firmly can make the finished loaf dense. Wash your hands and any surfaces that touched raw meat with hot, soapy water.
- Shape a shallow ring. Transfer the mixture to a microwave-safe, shallow round dish, such as a glass pie plate. Shape it into a ring about 8 inches (20 cm) across, with a 2- to 3-inch (5- to 7.5-cm) opening in the center. Keep the ring an even thickness, around 1 1/2 inches (4 cm), so it cooks at a similar rate throughout. Do not use metal, foil, or a dish that is not labeled microwave-safe.
- Add the topping and cover. Spread the remaining 2 tablespoons of ketchup over the top. Cover the dish loosely with a microwave-safe lid or vented microwave-safe wrap; the cover helps retain moisture, while the vent lets steam escape. Make sure the cover does not touch the meat if it could become hot or stick.
- Microwave the meatloaf. Set the dish on the turntable and cook on HIGH for 10 minutes in a 1,000-watt microwave. Rotate the dish if your microwave does not have a turntable, then cook for 4 more minutes. These are guide times, not a substitute for checking the center: microwave wattage, dish shape, and the loaf’s thickness all affect how quickly it cooks.
- Check the temperature and finish cooking. Insert an instant-read food thermometer into the thickest part of the meat, avoiding the dish. Check a few spots, including areas near the inner and outer edges of the ring. Ground beef must reach the USDA FSIS safe minimum internal temperature of 160°F (71°C). If it has not reached that temperature, microwave in 1-minute bursts and check again after each one. At 1,000 watts, many 1-pound loaves take about 14–16 minutes altogether; lower-powered microwaves may take longer.
- Rest before slicing. Once the meatloaf reaches 160°F (71°C), leave it covered and let it stand for 5 minutes. The dish and juices will be hot, so lift the cover away from you to avoid steam. Check the center again if you have any doubt that the loaf cooked evenly. Slice with a clean knife and serve hot.
Tips
- Use temperature, not appearance, to judge doneness. The topping can brown or bubble before the center is cooked through, and microwave-cooked beef may look different from oven-baked meatloaf. A food thermometer is the reliable check. If you have a small thermometer, insert it from the side into the thickest portion for a useful reading.
- Keep the ring even and relatively shallow. A tall, tightly packed loaf can heat unevenly, leaving the middle underdone while the edges become dry. Make a clear opening in the center and keep the meat layer close to the same thickness all around. If your dish is too small to shape a ring, divide the mixture into two shallow portions and cook them separately.
- Make practical substitutions. Panko or crushed plain crackers can replace the breadcrumbs in the same volume; panko may give a slightly looser texture, while crackers can taste saltier. If you do not have Worcestershire sauce, use soy sauce in the same amount for a saltier, less tangy flavor. Finely grated onion can replace chopped onion, but it releases more liquid, so the loaf may be softer.
- Mix lightly and handle raw meat carefully. Overmixing compresses the mixture, and adding extra milk without adjusting the crumbs can make it hard to shape. Keep the raw meat separate from ready-to-eat foods, and clean utensils and work surfaces promptly after shaping.
Serving Suggestions
Serve slices with mashed potatoes, steamed green beans, peas, or a crisp salad for a simple dinner. The ketchup topping is sweet and tangy, so plain sides balance it well; you can also offer extra ketchup or a little brown gravy at the table. If serving several people, slice the loaf after its rest and spoon any juices from the dish over the meat, rather than pouring hot juices onto the sides.
For a quick sandwich, let a slice cool slightly and tuck it into toasted bread with lettuce, sliced tomato, or a little mustard. Microwave meatloaf can be more delicate than a firm oven-baked loaf, so use a broad spatula to lift slices from the dish. A small portion of leftover meatloaf also works crumbled into a cooked tomato sauce, where it can be served over pasta.
Variations
Change the meat: Ground turkey or chicken can replace the beef, but poultry needs to reach 165°F (74°C), the USDA FSIS safe minimum for poultry. Check the center with a thermometer and expect the timing to vary with the shape and microwave. Ground pork can be used in place of beef or in a blend, but ground meat mixtures still need to reach 160°F (71°C).
Adjust the seasonings: Add 1 teaspoon (5 ml) of Dijon mustard for a sharper topping, or use a pinch of dried thyme or smoked paprika in the meat mixture. For a less sweet finish, replace the ketchup topping with a thin layer of tomato sauce. Keep additions modest: large amounts of wet sauce or chopped vegetables can change the texture and lengthen cooking.
Make it without dairy: Use an unsweetened, unflavored plant beverage in place of the milk, in the same quantity. The breadcrumbs need only enough liquid to moisten, so add it gradually if the alternative is particularly thin. For a different texture, quick oats can stand in for breadcrumbs, though the loaf may be softer and less finely textured.
Storage and Reheating
Refrigerate cooked meatloaf within 2 hours of cooking, storing it in a shallow, covered container. Keep it refrigerated for 3–4 days. For easier reheating, slice the loaf before chilling and store the slices with any cooking juices; this helps the portions stay moist and makes it easier to warm only what you need. Do not leave cooked meatloaf at room temperature for more than 2 hours.
To reheat a portion, place it in a microwave-safe dish with a teaspoon of water or broth, cover loosely, and heat in short bursts, turning the slice once if practical. Reheat leftovers to 165°F (74°C), checking the center with a food thermometer. Larger portions can take longer, so avoid relying on one fixed reheating time. Freeze tightly wrapped slices for up to about 3 months for best quality; thaw in the refrigerator and reheat to 165°F (74°C).
Frequently Asked Questions
How long does a 1-pound meatloaf take in a 1,000-watt microwave?
Plan on about 14–16 minutes on HIGH for the shallow ring in this recipe, then let it rest for 5 minutes. Start checking after 14 minutes, because a wide dish or a particularly thin ring may cook sooner. The loaf is ready only when the thickest part reaches 160°F (71°C).
How long should I cook meatloaf in a lower-wattage microwave?
A lower-wattage microwave will generally need more time, but there is no dependable minute-for-minute conversion because dish shape and microwave heating patterns matter too. Cook in short additional intervals and check the center with a food thermometer. Do not serve ground beef until it reaches 160°F (71°C).
Can I cook meatloaf in a solid loaf shape?
You can, but a thick solid shape is more likely to cook unevenly in a microwave. A ring leaves space in the middle and keeps the meat layer relatively shallow. If you prefer a solid loaf, use a shallow microwave-safe dish and shape the mixture no thicker than about 1 1/2 inches (4 cm); still verify the temperature in several places.
Should I cover meatloaf while it cooks in the microwave?
Yes. A loose, vented microwave-safe cover helps limit splattering and reduces moisture loss. Do not seal the dish tightly, and do not use foil or a metal lid. Take care when uncovering it after cooking because trapped steam can burn.
Can I prepare the meatloaf mixture ahead?
You can mix and shape it ahead, cover it, and refrigerate it until you are ready to cook, but cook it within 24 hours for best quality. Keep it cold and do not leave raw ground beef at room temperature while preparing other parts of the meal. A chilled loaf may take longer in the microwave, so check its center temperature rather than relying only on the recipe time.
Why is my microwave meatloaf watery or crumbly?
Too much liquid, a very wet onion, or insufficient breadcrumbs can make the mixture soft; too few binders or overcooking can make slices crumble. Measure the milk and breadcrumbs, chop the onion finely, and let the loaf rest for 5 minutes before slicing. If the mixture seems loose before cooking, mix in 1 tablespoon (about 7 g) of breadcrumbs and let it stand briefly before shaping.
