I sliced thick rounds of sweet onions, soaked them in buttermilk, then dredged them in a mix of panko and freshly grated parmesan cheese.

How to Make Parmesan Crusted Onion Rings at Home
The perfect parmesan crusted onion ring batter
The secret to a great parmesan crusted onion ring lies in the prep. Start with large, thick-cut onion slices—sweet onions work best for balance. For the batter, you’ll want three layers: flour for grip, buttermilk for moisture, and a crunchy coating made from panko breadcrumbs and finely grated parmesan cheese. The parmesan crust is what sets this onion ring apart. It melts and crisps at the same time, locking flavor into every edge of the ring.

When mixing your dry ingredients, don’t skip the seasoning. A bit of garlic powder, paprika, salt, and cracked pepper take these parmesan crusted onion rings to another level. Dip each onion ring in flour, then buttermilk, then that cheesy breadcrumb mix. Press firmly to get an even coat so the parmesan sticks during frying. I often prep my parmesan crusted onion rings while my oil heats to 350°F—ideal for a crisp, even fry.
Oven-baked and air fryer parmesan crusted onion ring options
While deep frying delivers unbeatable crunch, baked parmesan crusted onion rings are a lighter alternative. Simply place the coated rings on a baking rack, spray lightly with oil, and bake at 425°F for 18–20 minutes, flipping halfway through. You’ll get a golden parmesan crust without extra oil. For an air fryer version, reduce the temperature slightly—390°F works best—and cook for about 12–14 minutes.
Whether fried, baked, or air-fried, the parmesan crusted onion ring holds up beautifully in any method. I always recommend a test batch—adjust your cook time slightly based on ring thickness. Want to elevate the flavor further? Try mixing in crushed herbs like parsley or rosemary into your parmesan before coating. These parmesan crusted onion rings also pair wonderfully with cool Greek yogurt dips or spicy sriracha ketchup.
The best part? These parmesan crusted onion rings can be made ahead. Freeze them after breading and pop into the oven or fryer straight from frozen. They stay just as crisp and cheesy.
Best Ways to Serve Parmesan Crusted Onion Rings
Parmesan crusted onion ring dips you’ll love
A parmesan crusted onion ring is already flavorful on its own, but the right dip can take it to addictive new levels. One of my favorites is a smoky chipotle aioli—its creamy heat complements the rich parmesan crust perfectly. Another crowd favorite? A simple homemade ranch with extra dill and garlic. The tang cuts through the fried cheese in every bite. If you’re feeling bold, try a roasted red pepper spread or even a warm marinara. Parmesan crusted onion rings have a strong flavor base, so they can handle bold dips.

For casual gatherings, I like to serve a tray of parmesan crusted onion rings with three dips in the center. It’s easy, it’s fun, and people can mix and match. If you’re setting a holiday table or game day platter, pair them with loaded cheese fries or mini BBQ sliders. These parmesan crusted onion rings also shine on a burger. Just stack one or two rings on top of a patty with your favorite cheese—it adds instant texture and flavor.
Pairing parmesan crusted onion rings with meals
These parmesan crusted onion rings aren’t just appetizers. They work beautifully as a side dish too. I often serve them next to grilled chicken, pulled pork, or even a hearty veggie sandwich. The crispy parmesan crusted onion ring adds just the right crunch to contrast with soft proteins or tender buns.
For a fun twist, turn your parmesan crusted onion ring into a taco topping. Lay them over pulled beef or crispy tofu with slaw and drizzle with spicy mayo. Want to get even more creative? Use mini parmesan crusted onion rings as garnish for loaded mashed potatoes or creamy mac and cheese. They hold up surprisingly well when stacked onto savory, creamy dishes.
Wherever you serve them, these parmesan crusted onion rings never last long. Their bold flavor and addictive crunch keep guests coming back for seconds—and thirds.
Make-Ahead Tips and Storage for Parmesan Crusted Onion Rings
How to store parmesan crusted onion rings
Leftovers of parmesan crusted onion rings are rare—but when they do happen, proper storage makes all the difference. First, let your parmesan crusted onion rings cool completely. If you seal them while warm, the steam will turn that crispy crust soggy. Once cooled, store them in a single layer in an airtight container lined with paper towels. This absorbs extra oil and helps preserve that parmesan crunch.
These parmesan crusted onion rings stay fresh in the fridge for up to 3 days. For longer storage, freeze them. Arrange the onion rings in a single layer on a parchment-lined baking sheet and freeze for 1 hour. Then transfer them to a freezer-safe bag or container. This method prevents sticking and keeps each parmesan crusted onion ring intact.
Best reheating methods for maximum crunch
Reheating parmesan crusted onion rings the right way is essential if you want to restore that crisp, cheesy crust. Avoid the microwave—it turns your crispy onion rings rubbery. Instead, use an oven or air fryer. For oven reheating, preheat to 375°F and spread the parmesan crusted onion rings on a wire rack over a baking sheet. Heat for about 8–10 minutes, flipping once for even crisping.
In an air fryer, set the temperature to 370°F and reheat for 4–6 minutes. The parmesan crisps right back up and the onion inside stays tender. For stovetop lovers, a quick shallow re-fry in oil over medium heat works too—just 1–2 minutes per side.
If you’re planning ahead, you can prep the parmesan crusted onion rings and freeze them raw. Bread the onion slices, lay them on a tray, and freeze. Once solid, store them in bags for up to 2 months. Then just fry, bake, or air fry straight from frozen—no need to thaw. It’s the easiest way to keep parmesan crusted onion rings ready to go for parties or weeknight cravings.

These parmesan crusted onion rings also make a fantastic make-ahead side. Prep in the morning, refrigerate, and fry fresh right before serving.

Frequently Asked Questions About Parmesan Crusted Onion Rings
Why soak onions in ice water before making onion rings?
Soaking onions in ice water helps tone down their sharp bite, making them milder and sweeter. It also firms them up, which results in crispier onion rings when fried. For parmesan crusted onion rings, this step ensures the sweet onion center balances the rich, cheesy crust perfectly.
How do you make Parmesan cheese and onion crisps?
Parmesan cheese and onion crisps are typically made by mixing finely sliced onions with shredded parmesan cheese, then baking small mounds on a parchment-lined sheet at 375°F until golden and crisp. While these are different from parmesan crusted onion rings, they deliver a similar cheesy-onion flavor in a lighter snack form.
Why soak onions in milk before frying?
Soaking onions in milk softens their texture and enhances natural sweetness. Milk also adds a touch of richness that pairs well with the savory coating in a parmesan crusted onion ring recipe. It helps the flour and breadcrumb mixture stick better too.
Why are Sonic’s onion rings so sweet?
Sonic’s onion rings taste sweet because they use sweet onions and dip them in a batter that contains vanilla ice cream. The subtle sweetness contrasts with the salty crust. While it’s not a parmesan crusted onion ring, that same balance of sweet and savory is what makes both versions so addictive.
