Mozzarella stick onion rings are a show-stopping party snack that unite two all-time favorites into one irresistible bite. Crisp golden breading gives way to melting mozzarella tucked neatly between tender onion rings—perfect for dipping and pulling apart. This recipe is a must when you need something fun but seriously satisfying for game night or movie marathons.
The first time I made these for a group of friends their eyes practically popped out at the cheese pulls. Now these onion rings are a regular request at every get-together.
Ingredients
- White onions: Large size for sturdy rings; seek out onions that feel heavy and firm
- Mozzarella cheese: Sliced block cheese melts best; look for a fresh block in the deli section for supreme stretch
- Plain flour: Important for even breading; choose an unbleached variety for best texture
- Large eggs: Create a sticky base for breadcrumbs; use extra fresh eggs for more binding power
- Breadcrumbs: Classic for crunch; panko can be used for extra crispiness
- Vegetable oil: Neutral taste and high smoke point; use fresh oil for each batch to prevent scorching
- Marinara sauce: Tangy rich dip; look for a low sugar variety with plenty of real tomato flavor
Step-by-Step Instructions
- Prep the Onions and Cheese:
- Peel your onions and slice into rings about one centimeter thick. Gently separate the rings without breaking them. Slice mozzarella into even strips. Nestle a smaller onion ring inside a larger one and pack the space between with mozzarella strips. If you love cheese, go ahead and add an extra layer. Repeat until you have several assembled rings. Lay the stuffed rings out on a tray and place in the freezer for at least one hour to help them hold together during dipping.
- Set Up Breading Station:
- Set out three wide bowls. Fill one with plain flour, one with beaten eggs, and one with breadcrumbs. Take your frozen stuffed onion rings from the freezer and keep them close by.
- Coat the Onion Rings:
- Gently dip each frozen ring in flour to help the egg stick. Next, coat thoroughly in beaten egg, making sure to cover the entire surface. Transfer to the breadcrumbs and press them gently into all sides. For a crunchier shell, dip the ring back into the egg then into breadcrumbs once more for a double coating. Lay breaded rings on a clean tray and return to the freezer until ready to fry, which keeps the cheese from melting out too soon.
- Fry to Golden Perfection:
- Pour enough vegetable oil into a deep pot to submerge the onion rings. Heat to 175 degrees Celsius. Use a thermometer if possible for accuracy. Fry the rings in small batches, turning gently until each side is golden brown and the cheese is just beginning to melt. This usually takes two to three minutes per batch. Do not crowd the pot as it drops the oil temperature and risks greasy rings. Remove with a slotted spoon and drain on a paper towel lined plate.
- Serve and Enjoy:
- Pile the hot mozzarella onion rings onto a platter and serve with warm marinara sauce for dipping. The best part is watching everyone pull the rings apart and see that cheesy stretch.

The layered mozzarella is definitely the showstopper here. Once my niece helped me assemble the rings and could hardly wait an hour for them to freeze, she was so eager to see that gooey cheese pull. Now it is our favorite way to bond in the kitchen.
Storage Tips
Let cooked rings cool completely before storing. Keep in an airtight container in the fridge for up to three days. Reheat in the oven or air fryer to restore crispness. You can also freeze the un-fried breaded rings on a tray, then store in freezer bags. Fry straight from frozen as needed; no need to thaw for best results.
Ingredient Substitutions
If you do not have mozzarella, try Monterey Jack for similar meltiness or provolone for a sharper taste. Panko breadcrumbs can be swapped for classic ones if you want even more crunch. For a gluten-free option, choose gluten-free flour and crumbs.
Serving Suggestions
These are a star on any appetizer spread and also work great alongside burgers or chicken wings. For an extra punch, drizzle with garlic butter before serving or add a spicy ranch or sriracha mayo for dipping next to the classic marinara.
Cultural and Historical Context
Stuffed onion rings are not traditional but combine the best of American diner culture. Classic onion rings originated in the early twentieth century, and adding mozzarella gives a nod to beloved Italian American comfort foods like mozzarella sticks and pizza.
