Introduction

These mozzarella-stuffed onion rings are a delightful twist on a classic snack. Crispy on the outside and filled with gooey melted cheese, they make a perfect appetizer or party treat that everyone will love.

A stack of three round, golden brown fried cheese croquettes sits on a white speckled plate placed on a wooden table. Each croquette has a crispy, crumbly outer layer with a rich orange hue. The middle of each item oozes creamy white melted cheese that slightly drips down. Fresh green chopped herbs are sprinkled on top and around the croquettes, adding a fresh contrast to the warm colors. The background features a blurred white marbled texture, and the overall scene has a warm, cozy atmosphere. photo taken with an iphone --ar 4:5 --v 7

Ingredients

2 large white or yellow onions (sliced into thick rings)
8 oz low-moisture mozzarella (cut into strips to fit inside onion rings)
1 cup all-purpose flour (for dredging)
2 eggs (beaten)
1.5 cups panko breadcrumbs (for extra crunch)
1 tsp garlic powder
0.5 tsp black pepper (freshly ground)
0.5 tsp salt
2 cups vegetable oil (for frying)
1 tbsp chopped fresh parsley (for garnish)
1 tsp chili flakes (optional heat)

Instructions

Step 1: Slice onions into ½-inch thick rings and pair similar sizes together. Cut mozzarella into strips and sandwich them between two onion rings to form a filled ring.
Step 2: Place the assembled stuffed rings on a tray and freeze for at least 30 minutes to keep the cheese from leaking during frying.
Step 3: Dredge each frozen ring in flour, dip in beaten egg, then coat in panko breadcrumbs mixed with garlic powder, salt, and pepper. Repeat egg and panko for extra crunch.
Step 4: Heat oil in a deep pan to 350°F (175°C). Fry 2–3 rings at a time for 2–3 minutes per side or until golden brown. Drain on paper towels.
Step 5: Garnish with parsley and chili flakes if desired. Serve hot with dipping sauces like garlic aioli, sriracha mayo, or marinara.

Tips & Variations

Ensure the onion rings are thoroughly frozen before frying to prevent cheese from leaking out.
Use low-moisture mozzarella for less water content and better melting consistency.
For a spicier kick, add chili flakes to the breadcrumb mixture.
Try using different cheeses like pepper jack or cheddar for varied flavors.

Storage

Store leftover onion rings in an airtight container in the refrigerator for up to 2 days. Reheat in an oven or air fryer at 350°F (175°C) for 5-7 minutes to restore crispiness. Avoid microwaving, as it can make the coating soggy.

How to Serve

A stack of four round, golden brown, crispy fried cheese croquettes with a crunchy texture sits on a white plate speckled with brown dots, placed on a wooden surface. Each croquette shows a creamy white cheese filling that oozes slightly out of a bite or crack on the side. Fresh green herbs are sprinkled on top of the croquettes and scattered around the plate to add a pop of color. The background is softly blurred with warm light, focusing on the detailed texture of the crispy outer layer and the smooth, melty cheese inside. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I bake the mozzarella-stuffed onion rings instead of frying?

Yes, you can bake them at 400°F (200°C) for about 15-20 minutes, flipping halfway through. However, frying yields the crispiest texture.

How do I prevent the cheese from leaking out during cooking?

Freezing the assembled rings before coating and frying helps the cheese stay in place. Also, make sure to coat them well with flour, egg, and breadcrumbs for a secure crust.
