Ingredients You’ll Need
Simple ingredients are the secret to big flavors! Every component of these Mozzarella Stick Onion Rings adds something crucial, whether it’s crunch, melt, or that savory finish that keeps you coming back for another.
- White onions: Large, sweet onions provide sturdy rings and boost the flavor with their natural sweetness.
- Mozzarella cheese: Mild, meltable, and perfect for those epic cheese pulls between every onion ring bite.
- Plain flour: Helps the egg and crumb coating stick, creating a barrier that keeps the cheese inside as it melts.
- Eggs: Whisked eggs work as the glue that holds all the crumbly goodness together.
- Breadcrumbs: Make sure to use fine, fresh breadcrumbs for maximum crunch and golden color.
- Vegetable oil: A neutral oil with a high smoke point is essential for perfectly fried and ungreasy rings.
How to Make Mozzarella Stick Onion Rings
Step 1: Prep the Onions
Start by peeling your large white onions and slicing them into thick, generous rounds, about half an inch each. Gently separate the layers into rings, then pair them based on similar size, with one just a touch larger than the other—this way, the cheese has a snug home to melt inside. The double layering is key for keeping all the mozzarella gooey and safe inside!
Step 2: Add the Cheese
Slice your mozzarella cheese into strips that fit neatly between each of your onion ring pairs. Sandwich the cheese between the two rings, pressing carefully to seal them together. This is where the magic begins, as the cheese melts into one perfect, cheesy layer during frying.
Step 3: Coat the Rings
Set up your breading station with three bowls: one for flour, one for whisked eggs, and one for breadcrumbs. Dredge each onion-cheese sandwich first in flour, tapping off any excess, then in the egg, and finally in the breadcrumbs, making sure every nook and cranny is coated. For extra crunch, give each ring another dunk in the egg and breadcrumbs—a double breading is totally worth the extra minute!
Step 4: Fry
Heat your vegetable oil in a sturdy pan to around 170°C (340°F). When it’s shimmering, carefully lower in your Mozzarella Stick Onion Rings and fry in batches. In just 2–3 minutes, they’ll puff up and turn irresistibly golden and crispy. Let them drain on paper towels so they stay crunchy, not greasy.
Step 5: Serve
Serve your piping-hot Mozzarella Stick Onion Rings with bowls of marinara, ranch, or your favorite dip. The mix of melty cheese, sweet onion, and crackling crust delivers pure joy in every dunk and bite. Try to resist eating them all from the plate before your guests arrive!
How to Serve Mozzarella Stick Onion Rings

Garnishes
Add a shower of fresh chopped parsley, basil, or a quick sprinkle of flaky sea salt for a burst of color and freshness. If you want to amp things up, shave a little Parmesan over the top while the rings are hot—it melts just enough to add a nutty finish.
Side Dishes
These Mozzarella Stick Onion Rings love good company! Pair them with classic burgers, grilled hot dogs, or a crisp green salad for balance. They’re also the ultimate snack tray centerpiece alongside wings, sliders, or crispy potato wedges.
Creative Ways to Present
Skewer the rings and thread them onto a stick for a fun, handheld twist. Or build a tower of Mozzarella Stick Onion Rings for a jaw-dropping appetizer display. Serving in small paper cones with a trio of dipping sauces lets everyone grab and mingle without any mess.
Make Ahead and Storage
Storing Leftovers
If you have any rings left (we doubt it!), let them cool fully, then store in an airtight container in the fridge for up to 3 days. Layer parchment between them to prevent sticking and preserve their crunchy coating.
Freezing
These Mozzarella Stick Onion Rings can absolutely be frozen! After frying and cooling, arrange them on a baking sheet in a single layer, freeze until solid, then transfer to freezer bags or containers. They’ll stay delicious for up to a month.
Reheating
To keep that crispy crunch, reheat them straight from the fridge or freezer in an oven or air fryer at 180°C (350°F) until hot and sizzling, about 8–10 minutes. Avoid microwaving, as that can make them soggy.
FAQs
Can I use red onions or sweet onions instead?
Yes, absolutely! While white onions offer a mild bite, red onions will give a pop of color and extra sweetness, and Vidalia or other sweet onions offer a milder, more delicate flavor.
What’s the best way to keep the cheese from leaking out?
Be sure your mozzarella slices fit snugly between onion rings and that your coating fully covers any cracks or gaps. Double breading forms a thick, reliable crust that keeps the melty cheese inside where it belongs.
Can I bake these instead of frying?
You can, though the results will differ slightly. Bake the assembled rings on a parchment-lined tray at 220°C (425°F) for about 15–18 minutes, flipping halfway through, for a lighter but still crispy coating.
Which dipping sauces go best with Mozzarella Stick Onion Rings?
Classic marinara is a winner, but ranch, garlic aioli, sriracha mayo, or even a spicy buffalo dip are delicious with the cheesy, crispy rings.
Can I prep Mozzarella Stick Onion Rings ahead of time?
Yes—assemble and bread the rings, then arrange on a tray, cover, and refrigerate up to 4 hours ahead. This makes them a perfect make-ahead snack for parties or game nights.
