Grease a muffin pan with cooking spray or oil and preheat the oven to 375°F (190°C).
Mix the ground beef with egg, breadcrumbs, ketchup, milk, chopped onion, garlic powder, Worcestershire sauce, salt, and pepper in a big bowl. Mix the ingredients well without working the meat too much.
Evenly divide the meat mixture among the muffin cups and press gently to shape. Put a small amount of ketchup on each meatloaf muffin.
Fourth, ensure that your oven is preheated before putting the meatloaf muffins in. Bake the muffins for 20 to 25 minutes until they are fully cooked and the center is no longer pink. Once you put a thermometer inside a muffin, it should show a temperature of 160°F, or 71°C.
Next, remove the muffin pan from the oven and let it cool for five minutes before taking out the muffins.
If you like, you can serve it warm with more ketchup or barbecue sauce on top.
Enjoy your tasty Mini Meatloaf Muffins with your favorite sides for a cozy and satisfying dinner.
