Pro Tip ✨

Check out the full list of ingredients and measurements in the recipe card below.

White onions: Choose large, firm onions to get those perfect thick rings that hold the filling nicely.
Mozzarella cheese: Shredded mozzarella melts smoothly, giving that irresistible gooey texture.
All-purpose flour: This creates the first layer of coating, ensuring the batter sticks well.
Eggs: They help bind the ingredients and create a rich batter for crispiness.
Breadcrumbs: Provide that satisfying crunch when fried or baked to golden perfection.
Parmesan cheese: Adds a salty, nutty flavor to the coating mix that complements the mozzarella beautifully.
Garlic: Minced fresh garlic brings an aromatic punch to the butter, elevating the entire dish.
Butter: The base for the garlic butter sauce that coats the onion rings and adds luscious richness.

Directions

Step 1: First, peel the onions and slice them into about 1/2-inch thick rings, carefully separating each ring from the onion. Choose the larger central rings for stuffing with mozzarella.

Step 2: Take a teaspoon or so of shredded mozzarella and carefully stuff it inside each onion ring, placing a second ring on top to sandwich the cheese. Repeat until all the cheese is used.

Step 3: Set up your breading stations: place the flour in one shallow dish, whisk the eggs in a second bowl, and mix the breadcrumbs with grated Parmesan in a third.

Step 4: Lightly dredge each stuffed onion ring in flour, shaking off excess. Then dip the ring into the beaten eggs, followed by a thorough coat of the breadcrumb-Parmesan mixture. For an extra crispy crust, you can double dip by repeating the egg and breadcrumb steps.

Step 5: In a skillet over medium heat, melt the butter with the minced garlic until fragrant, about 1-2 minutes. Be careful not to brown the garlic to keep it from becoming bitter.

Step 6: Add the coated onion rings to the garlic butter pan, frying them gently until golden brown and crisp on all sides, flipping carefully. This should take about 3-4 minutes per side. Alternatively, you can bake them at 425°F for 15-20 minutes until golden and cooked through.

Step 7: Once cooked, transfer the onion rings to a paper towel-lined plate to drain excess butter. Serve immediately for the best melty mozzarella experience, drizzling with extra garlic butter from the pan if desired.

Servings and Timing

This recipe makes about 4 servings as a delicious appetizer or snack. The prep time is around 20 minutes, mainly for slicing and stuffing the onions. Cooking takes roughly 15-20 minutes, whether frying or baking, bringing the total time to about 35-40 minutes. There’s no extensive resting time needed, but I recommend serving these hot right after cooking to enjoy the full gooey, crispy texture.

When I serve these mozzarella-stuffed onion rings, I like to keep the presentation simple yet inviting. They look fantastic piled high on a rustic wooden board or a bright platter lined with parchment paper to soak up any drips. A sprinkle of finely chopped fresh parsley or a dash of chili flakes adds a pop of color and a little extra flavor zing that I find delightful.

For sides, I often serve them alongside a tangy marinara or spicy aioli dipping sauce to complement the cheesy richness and crispy onion shell. They are perfect finger foods for game nights, casual parties, or even as a decadent side to a burger or steak. Personally, I prefer enjoying them warm so the mozzarella is irresistibly melted and gooey.

As for drinks, these onion rings pair beautifully with a crisp white wine like Sauvignon Blanc or an effervescent sparkling rosé. For non-alcoholic options, a zesty lemonade or an iced herbal tea balances the buttery richness perfectly. I find this recipe suited for any occasion that calls for a crowd-pleaser, whether it’s a laid-back family evening or a fun gathering with friends.

Variations

I love experimenting with this recipe by swapping in different cheeses—think sharp cheddar for a tangier kick or pepper jack for a spicy twist. If you want to make it vegetarian-friendly but dairy-free, try using vegan mozzarella alternatives; just be sure they melt well to maintain that gooey texture.

Looking for gluten-free options? Simply replace the all-purpose flour and breadcrumbs with gluten-free versions or almond flour for a nuttier flavor. You could even bake instead of fry the onion rings to keep things on the lighter side without sacrificing that golden crunch.

If you’re feeling adventurous, try adding fresh herbs like rosemary or thyme into the garlic butter or mixing in seasoning blends like smoked paprika, Italian herbs, or even a bit of cayenne pepper into the breadcrumb mix for an extra flavor boost. Different cooking methods like air-frying can also produce wonderfully crisp onion rings with less oil, which is a technique I use often for busy weeknights.

Storage and Reheating

Storing Leftovers

If you happen to have any leftovers (though I must admit, that’s rare in my house), place them in an airtight container and refrigerate. They will keep well for up to 2 days, but the texture is best enjoyed fresh, so try to consume them quickly to enjoy that crispy crust and melty inside.

Freezing

While you can freeze mozzarella-stuffed onion rings, I recommend freezing them before cooking. Arrange the breaded and stuffed onion rings on a parchment-lined tray and freeze until solid, then transfer into freezer-safe bags. This way, you can fry or bake them straight from frozen for about 5-7 minutes longer than usual. They should stay good for up to 3 months.

Reheating

The best way to reheat these onion rings is in the oven or air fryer to retain their crispiness. Avoid microwaving, as that tends to make the coating soggy and the cheese less stretchy. Preheat your oven to 375°F and heat the onion rings on a baking sheet for about 7-10 minutes until warmed through and crispy again.

FAQs

Can I use other types of onions instead of white onions?

Absolutely! Yellow onions also work well and are slightly sweeter, while red onions add a bit of color and a milder flavor. Just keep in mind that thicker rings from large onions will hold the cheese stuffing better.

What can I substitute if I don’t have mozzarella cheese?

You can try other melty cheeses like provolone, Monterey Jack, or even a mild cheddar. The key is to use a cheese that melts well to get that luscious, gooey effect inside the onion rings.

Is it necessary to make garlic butter for this recipe?

While the garlic butter elevates the flavor enormously and gives a rich finish, you can skip it if you prefer. However, I highly recommend it because it transforms the onion rings from classic to incredible, adding a savory depth you won’t want to miss.

Can I prepare these onion rings ahead of time?

You can absolutely prepare and bread the stuffed onion rings a few hours ahead and keep them refrigerated. Just wait to cook them until you’re ready so they stay crisp and fresh when served.

Are these safe for frying at home if I’m new to frying?

Yes! Frying can be simple if you keep the oil at a steady medium heat, around 350°F, and don’t overcrowd the pan. Using a heavy-bottomed pan or deep fryer helps maintain temperature. I always recommend having a slotted spoon and paper towels ready to drain excess oil for a perfect crispy finish.
