Crispy Cheesy Mozzarella Stuffed Onion Rings Recipe
Introduction
Crispy cheesy mozzarella stuffed onion rings are a delightful twist on a classic snack. Filled with gooey mozzarella and coated in a flavorful breadcrumb crust, they make a perfect appetizer or party treat. Enjoy them hot with a side of marinara sauce for dipping.

Ingredients
- 2 large onions, cut into 1/2-inch thick rings and separated
- 1 lb (450g) mozzarella cheese, cut into strips
- 1 cup all-purpose flour
- 2 large eggs, beaten
- 2 cups breadcrumbs
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon paprika
- Salt and pepper, to taste
- Vegetable oil, for frying
- Marinara sauce, for dipping (optional)
Instructions
- Step 1: Take two onion rings of different sizes and fill the gap between them with a strip of mozzarella cheese. Repeat this until all the onion rings are filled.
- Step 2: Place the assembled onion rings on a baking sheet lined with parchment paper and freeze for about 1 hour to set.
- Step 3: Prepare a breading station with three bowls: one with flour, the second with beaten eggs, and the third with breadcrumbs mixed with garlic powder, onion powder, paprika, salt, and pepper.
- Step 4: Dip each frozen stuffed onion ring first in flour, then in beaten eggs, letting the excess drip off, and finally coat with the seasoned breadcrumbs. Press gently so the coating sticks well.
- Step 5: Heat vegetable oil in a deep skillet or fryer to 350°F (175°C). Fry the breaded onion rings in batches for 2-3 minutes until golden brown and crispy. Avoid overcrowding.
- Step 6: Drain fried onion rings on paper towels. Serve hot with marinara sauce for dipping if desired.
Tips & Variations
- Use panko breadcrumbs for an extra crunchy coating.
- Try adding a pinch of chili powder to the breadcrumb mix for a spicy kick.
- Make sure to freeze the assembled rings well before breading to prevent cheese from leaking during frying.
Storage
Store leftover fried onion rings in an airtight container in the refrigerator for up to 2 days. Reheat in the oven at 350°F (175°C) for 5-7 minutes to maintain crispiness. Avoid microwaving as it can make the coating soggy.

FAQs
Can I use a different type of cheese?
Yes, you can substitute mozzarella with other mild, meltable cheeses like provolone or cheddar. Just ensure the cheese melts well without releasing too much oil.
Can I bake these instead of frying?
Baking is possible but may result in less crispy onion rings. To bake, place the breaded rings on a greased baking sheet and bake at 400°F (200°C) for about 15-20 minutes, turning halfway through.

Ingredients
Onion Rings and Filling
- 2 large onions, cut into 1/2-inch thick rings and separated
- 1 lb (450g) mozzarella cheese, cut into strips
Breading
- 1 cup all-purpose flour
- 2 large eggs, beaten
- 2 cups breadcrumbs
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon paprika
- Salt and pepper, to taste
For Frying and Serving
- Vegetable oil (enough for deep frying)
- Marinara sauce (optional, for dipping)
Instructions
- Preparation: Take two onion rings of different sizes and fill the gap between them with a strip of mozzarella cheese. Repeat this process until you have filled all the onion rings, creating stuffed onion ring sandwiches.
- Freeze the Stuffed Rings: Place the assembled stuffed onion rings on a baking sheet lined with parchment paper and freeze for about 1 hour to firm them up and help the cheese stay in place during frying.
- Set Up Breading Station: Prepare three bowls for the breading process: one with all-purpose flour, the second with beaten eggs, and the third with breadcrumbs mixed with garlic powder, onion powder, paprika, salt, and pepper.
- Bread the Onion Rings: Dip each frozen stuffed onion ring first into the flour, making sure it is completely coated. Next, dip into the beaten eggs, letting any excess drip off, and finally coat evenly with the seasoned breadcrumb mixture. Press gently to ensure the breadcrumbs adhere firmly.
- Heat Oil: In a deep skillet or fryer, heat vegetable oil to 350°F (175°C) to prepare for frying.
- Fry the Onion Rings: Fry the breaded stuffed onion rings in batches for about 2-3 minutes each, or until they turn golden brown and crispy. Avoid overcrowding the pan to maintain oil temperature and crispiness.
- Drain and Serve: Remove the onion rings with a slotted spoon and drain on paper towels to remove excess oil. Serve immediately while hot, with marinara sauce on the side for dipping, if desired.
Notes
- Freezing the stuffed onion rings before breading helps keep the cheese inside during frying and prevents leaking.
- Ensure the oil temperature remains consistent at 350°F to achieve a crispy coating without soaking up excess oil.
- You can substitute mozzarella cheese with another mild melting cheese if preferred.
- For a gluten-free version, use gluten-free flour and breadcrumbs.
- Serve immediately for the best texture and taste as the cheese inside is best enjoyed warm and melty.
