Golden onion rings stuffed with gooey mozzarella are my go to move whenever someone needs an impressive snack fast or the kids start craving crispy cheese. The combination of crunchy breading and a stretchy cheese core never disappoints. In fact, this dish has become our family’s signature party treat because it feels indulgent yet approachable.
I first made these when my neighbor dropped by hungry and unannounced. The plate was empty before we could even sit down. Now I make a double batch every game night.
Ingredients
- Large onion: thick rings hold their shape so the filling stays put
- Mozzarella cheese sticks: the classic choice for melted stretch and lift
- Whole milk: thins out the batter for smooth even coating
- Egg: brings structure to the batter for a silky dip
- Panko breadcrumbs: are a must for a shatteringly crisp crust
- Cooking oil: choose something neutral with a high smoke point like canola or vegetable
- Toothpicks: keep your onion and cheese stacked together for clean frying
- Baking powder: gives the batter a slight puff so the crust is not too dense
- All purpose flour: helps the batter stick and creates the crispy shell
- Fine salt: ties all the flavors together and cuts the richness
Instructions
- Assemble The Onion Cheese Rings:
- Nest thick and thin onion rings together to create a hollow center and gently insert mozzarella cut to fit Secure each ring stack with a toothpick so the cheese stays in the center
- Mix The Dry Coating:
- Combine flour baking powder and salt in a wide bowl Mix well so everything is evenly distributed Dredge each filled onion ring in this mixture and transfer to a wire rack
- Prepare The Batter:
- Whisk egg and milk in a separate bowl Pour the liquid over any leftover flour mixture and stir until you have a smooth thick batter
- Coat With Breadcrumbs:
- Dip each floured onion ring into the batter letting the excess drip off then coat in Panko breadcrumbs pressing lightly for even coverage Return rings to a rack to rest
- Fry To Golden Perfection:
- Heat oil in a deep pan to about three hundred fifty degrees Fahrenheit Fry the rings in batches turning so both sides become deeply golden Brown for three to four minutes Drain on a plate lined with paper towels
- Finish And Serve:
- Carefully remove toothpicks so the cheese does not pull out Serve hot with marinara sauce or your favorite dip for a full comfort food experience

The Panko is my favorite part as it gives each bite an audible crunch One family game night the first batch disappeared so fast we barely managed to save a couple for the kids
Storage Tips
Enjoy these hot and fresh for best flavor but leftovers keep in the fridge for two days Use an oven or air fryer to bring back that crunch at three hundred seventy five degrees Avoid the microwave as it can soften the crust too much
