Method
Prep and mix
- Preheat the oven to 375°F and grease a 12-cup muffin tin. Set the tin on a sheet pan so it moves easily.
- Combine ground beef, breadcrumbs, eggs, whole milk, finely grated small onion, minced cloves garlic, Worcestershire sauce, garlic powder, onion powder, and salt and pepper until just mixed. Stop when no dry bits remain to avoid dense mini meatloaves.
Shape, glaze, and bake
- Divide the meat mixture evenly among the muffin cups, pressing gently to compact. Keep the tops level for even caramelization.
- Mix ketchup, brown sugar, and mustard for the glaze, then spoon about 1 teaspoon over each mini meatloaf. Make sure the glaze covers the top surface.
- Bake at 375°F for 20–25 minutes until the internal temperature reaches 160°F and the tops are caramelized. Look for a glossy, browned ketchup layer that has set on top.
Rest and serve
- Rest the mini meatloaves for 5 minutes before removing them from the tin. The glaze should look firm and the centers should stay juicy when you lift one out.
Notes
Pro tip: finely grate the onion so it disperses through the meat without big chunks. Refrigerate leftovers in an airtight container for up to 3 days; reheat in a 325°F oven until warmed through. Freezing works well—freeze cooled mini meatloaves for up to 2 months and thaw overnight in the fridge. For a lower-fat option, use 90% lean ground beef and expect slightly less moisture.
