Cheesy Mozzarella Onion Rings

This crispy mozzarella-filled onion ring dish is my go to when guests drop by unexpectedly or when my kids are craving something cheesy and satisfying without a lot of fuss. It is the perfect indulgent treat that balances crunch with melted comfort.

I first made this when my neighbor popped over unannounced and I needed a quick snack that felt like more than chips. She asked for the recipe before she left.

Ingredients

• Large onion: thick rings give structure and create the perfect pocket for stuffing
• Mozzarella cheese sticks: melt easily and stretch for that classic pull
• Whole milk: helps loosen the batter for even coating
• Egg: acts as a binder to bring the wet ingredients together
• Panko breadcrumbs: ensure an extra crispy finish compared to regular crumbs
• Cooking oil: must be neutral and high heat stable like canola or vegetable
• Toothpicks: are essential for securing the rings while frying
• Baking powder: helps the batter puff slightly during frying
• All purpose flour: provides a base for both dredging and batter
• Fine salt: enhances all the other flavors and balances the richness

Instructions

Assemble The Onion Cheese Rings:

Pair two onion slices one smaller and one larger then insert the smaller into the larger leaving a small gap Fill the gap with mozzarella cut to size and secure the structure with a toothpick

Mix The Dry Coating:

Combine flour baking powder and salt in a bowl Stir thoroughly to distribute the leavening and seasoning evenly Coat the filled onion rings in the dry mix and set them on a wire rack

Prepare The Batter:

Whisk milk with the beaten egg until fully blended Pour into the leftover dry mix and stir gently until a smooth thick batter forms

Coat With Breadcrumbs:

Dip each flour coated onion ring into the batter letting excess drip off Then press into a shallow bowl of Panko breadcrumbs until evenly coated Return to the wire rack to set briefly

Fry To Golden Perfection:

Heat oil in a deep pot to around 350 degrees Fahrenheit Fry the rings in batches turning once until both sides are deeply golden Drain on a paper towel lined plate

Finish And Serve:

Remove the toothpicks carefully Serve immediately while hot with a small bowl of warm marinara sauce

I love how the Panko creates that unmistakable crunch you hear when you bite in One time we had friends over and the plate was gone in minutes even before I could set down the sauce

Storage Tips

These onion rings are best eaten fresh but you can refrigerate leftovers in an airtight container for up to two days Reheat in an oven or air fryer at 375 degrees Fahrenheit to restore crispiness Avoid microwaving as it softens the texture

Common Questions About Recipes

→ How do I prevent cheese from leaking while frying?

Secure mozzarella between onion slices with toothpicks and use a double coating of flour, batter, and breadcrumbs to lock cheese inside.

→ Can I use different cheese types?

Yes, firm melting cheeses like provolone or pepper jack work well to maintain structure and melt quality.

→ Is there a gluten-free option?

Substitute all-purpose flour and breadcrumbs with certified gluten-free versions for a gluten-free variation.

→ How can I make the onion rings crispier?

Apply a thorough double coating: first with flour, then batter, and finish with panko breadcrumbs before frying.

→ Can these be prepared ahead of time?

You can assemble and refrigerate the rings prior to frying. Fry just before serving to keep them crisp.

Marinara pairs perfectly, but ranch or spicy aioli also complement the cheesy and crispy flavors well.
