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

Ingredient Substitutions

Try pepper jack if you like a little heat or provolone for a milder cheese stretch For gluten free needs use certified gluten free flour and Panko You might notice a slightly different crunch but it still works

Serving Suggestions

Serve with a bowl of warm marinara for dipping Ranch or garlic aioli also pair well These are great as the centerpiece at a party buffet or with burgers for a family dinner

Cultural Context

This appetizer is a mashup of classic fairground eats and beloved mozzarella sticks Deep fried treats with cheese are comfort staples in many American homes Onion rings with a surprise cheesy filling take party snacking to the next level

Seasonal Adaptations

Use sweet Vidalia onions in summer for milder flavor Add fresh chopped basil or oregano into the Panko for a fresh twist Serve with a bright tomato and cucumber salad during the warmer months

Success Stories

Everyone who has tried these asks for the recipe My cousin made them for her book club and they became the highlight of every future meeting One friend now insists on bringing a batch to every potluck

Freezer Meal Conversion

Assemble the rings and bread them then freeze on a tray Once frozen transfer to a freezer bag Fry straight from frozen adding an extra minute or two to the cooking time They turn out just as crispy

Culinary Inspiration: American

Yields: 4 Portion Size (16–20 stuffed onion rings)

Dietary Preferences: Vegetarian-Friendly

What You’ll Need

→ Onion Rings

01 2 large yellow onions, sliced into thick rings
02 8 ounces mozzarella cheese sticks, cut into strips to fit inside onion rings
03 Toothpicks, as needed to secure rings

→ Coating and Batter

04 1 cup all-purpose flour, plus extra for dredging
05 1 teaspoon baking powder
06 1/2 teaspoon fine salt
07 3/4 cup whole milk
08 1 large egg
09 2 cups Panko breadcrumbs
10 4 cups canola or vegetable oil, for frying

→ Serving

11 Marinara sauce, warmed, for serving (optional)

Step-by-Step Guide

Step 01

Separate the onions into rings. Nest a smaller ring inside a larger one, leaving a gap. Fit mozzarella strips into the gap between rings and secure with toothpicks.

Step 02

In a bowl, mix 1 cup flour, baking powder, and salt until evenly blended. Dredge the assembled onion rings in the dry mixture, coating thoroughly, and set aside on a wire rack.

Step 03

In a separate bowl, whisk milk and egg until smooth. Pour into the remaining flour mixture and stir until a batter forms.

Step 04

Dip each flour-dusted onion ring into the batter, allowing excess to drip off. Coat immediately in Panko breadcrumbs, pressing lightly to adhere. Place back on the rack to set.

Step 05

Heat oil in a deep pot to 350°F. Fry rings in small batches for 2–3 minutes per side until deep golden. Remove to a paper towel-lined plate to drain.

Step 06

Carefully remove toothpicks from each ring. Serve immediately with warm marinara sauce on the side.

Handy Tips

  1. For optimal crispness, assemble rings ahead of time and chill before frying.
  2. Double-coating (flour, batter, then breadcrumbs) helps prevent cheese leakage.
  3. Best enjoyed hot and fresh; reheating in the oven restores crunch.
