Cheesy Meatloaf Muffins Recipe

Preheat the oven to 375 degrees F. Spray two extra-large 6-cup muffin tins with nonstick cooking spray.

Mix milk, 3 tablespoons Italian dressing, mustard, and egg together in a large bowl. Mix in quick-cooking and old-fashioned oats followed by Swiss cheese, Parmesan cheese, and mozzarella cheese.

Let the mixture sit for 3 to 5 minutes. Mix in beef, onion, oregano, garlic, celery seed, garlic powder, salt, and pepper. Let sit for another 3 to 5 minutes to absorb liquid, as the mixture will seem very wet.

Scoop out mixture and mold into twelve 1/3- to 1/2-cup balls. Place into the prepared muffin tins. Drizzle tops with more Italian dressing.

Bake in the preheated oven until no longer pink in the centers and browned on top, 35 to 45 minutes. Remove muffins from the oven and drizzle tops with ketchup.

Set an oven rack about 6 inches from the heat source and preheat the oven’s broiler.

Broil in the preheated oven until ketchup is cooked and meat muffins are crispy, 5 to 10 minutes.
