- Large white onions: for a natural round shape and sweet flavor look for heavy onions with tight skin
- Mozzarella cheese slices: melt beautifully and stretch for that dramatic cheese pull buy whole milk mozzarella for best texture
- All purpose flour: helps create a dry surface for breading fresh flour gives a lighter coating
- Eggs: provide essential binding and help crumbs stick always use eggs at room temperature for easy blending
- Breadcrumbs: for crunch choose panko for extra crispiness or plain if you like a finer coating
- Oil for frying: use a neutral oil with a high smoke point like vegetable or canola ensure it is fresh for the cleanest flavor
- Marinara sauce for dipping: gives bright acidity and balances the richness of the cheese warm before serving
Step by Step Instructions
- Prepare the Onion Rings:
- Cut the ends off the onions and peel away the outer layers Slice each onion into rings about one centimeter thick Try to keep the rings as even as possible because this will help them fry up perfectly Separate the inner rings from the outer ones and match smaller rings inside larger rings for stuffing
- Stuff with Cheese:
- Cut mozzarella into even strips The cheese should fit comfortably between two onion rings but not overfill the gap Nestle strips into the space between each paired onion ring If you love extra cheese do an additional layer Place the prepared stuffed rings on a tray and freeze for about one hour This keeps the cheese inside while frying
- Bread the Onion Rings:
- Get three wide bowls ready one with flour one with beaten eggs and one with breadcrumbs Take a stuffed onion ring and roll it in flour making sure to cover every spot Then dip it in the egg letting excess drip off Roll it in breadcrumbs to fully coat For a thicker crunchy coating dip again in egg and breadcrumbs Place each completed ring back in the freezer to chill
- Fry to Crispy Perfection:
- Pour oil into a deep heavy pot to cover the rings by at least five centimeters Heat oil on medium high until a thermometer reads three hundred fifty degrees Fahrenheit or the oil sizzles when you drop a breadcrumb in Use a slotted spoon to carefully lower a few rings into the oil at a time Fry turning if needed until deep golden brown and crisp Watch carefully as cheese will start to ooze if cooked too long
- Drain and Serve:
- Use tongs or a slotted spoon to lift out the finished rings Set them on a paper towel lined plate to drain off extra oil Serve immediately with a side of hot marinara for dipping Enjoy the stretchy cheese and crunchy ring in every bite

So crowd pleasing they disappear fast every time I put a plate out My favorite part is pulling the rings apart and seeing that long string of cheese which is pure happiness at the table
Storage Tips
If you have leftovers cool rings completely before storing Place them in a single layer on a tray and freeze Once solid transfer to an airtight container or freezer bag They keep well for up to two months Reheat straight from frozen in a hot oven or air fryer to revive the crunch Never microwave or they go soggy
Ingredient Substitutions
