Meatloaf Meatballs
These Meatloaf Meatballs take the comfort of classic meatloaf and turn it into a fun, bite-sized format that’s perfect as an appetizer. They bake up juicy and flavorful in a muffin tin, with just the right touch of tangy ketchup on top. It’s a no-fuss, oven-friendly way to enjoy a nostalgic favorite.

Grated onion keeps them moist without chunks, and using a silicone muffin mold helps them hold shape and pop out cleanly. They’re great for weeknight dinners, lunchboxes, or as party bites with toothpicks.
Helpful Tips
- Grate the onion directly into the bowl. This keeps the mixture moist and adds flavor without big pieces.
- Don’t overmix. Stir just until everything is combined to keep the meatballs tender.
- Double baste with ketchup. Brushing on ketchup during baking and again at the end gives that signature meatloaf glaze without drying them out.
