Assemble the Doritos Sandwiches
Begin by pairing similarly sized Doritos chips. Place a small piece of mozzarella (approximately 1/2-inch cube or stick) between two chips to form a sandwich. Press gently around the edges so the chips stick together slightly. Continue this process until you've created all your Doritos-cheese sandwiches.
Create Your Breading Station
Set up three shallow bowls in a row: the first with all-purpose flour, the second with beaten eggs, and the third with breadcrumbs. This classic three-step breading station will create the perfect crispy exterior that seals in the melting cheese during frying.
Bread the Doritos Sandwiches
Working with one Doritos sandwich at a time, carefully coat it first in flour, covering all exposed areas while shaking off any excess. Next, dip it into the beaten eggs until completely coated. Finally, transfer to the breadcrumbs, gently pressing to ensure they adhere well to all surfaces. For extra crunch, you can double-coat by dipping in the egg and breadcrumbs a second time.
Heat the Oil
Pour vegetable oil into a deep skillet or heavy-bottomed pot to a depth of 2-3 inches. Heat the oil to 350°F (175°C), using a cooking thermometer to monitor and maintain this temperature throughout the frying process. Proper oil temperature is crucial for achieving the perfect crispy exterior while melting the cheese inside.
Fry Until Golden
Carefully lower a few breaded Doritos sandwiches into the hot oil, being careful not to overcrowd the pan (which would lower the oil temperature). Fry for 1-2 minutes per side until they achieve a beautiful golden-brown color and the cheese inside begins to melt. Use a slotted spoon or spider to remove them from the oil and transfer to a paper towel-lined plate to drain excess oil.
Serve Immediately
These delicious treats are best enjoyed hot when the cheese is still gooey. Arrange them on a serving platter alongside small bowls of marinara sauce, ranch dressing, or spicy aioli for dipping. Garnish with chopped parsley or a sprinkle of grated parmesan if desired.
