Ingredients You’ll Need
This recipe is wonderfully straightforward, relying on simple ingredients you probably already have on hand. Each component plays a crucial role: the onions provide sweetness and tenderness, the buttermilk adds moisture and tang that tenderizes, and the Parmesan and breadcrumbs combine for that unbeatable crunchy coating packed with flavor.
- 2 large onions: Selecting firm, large onions allows for perfect ring slices that hold their shape when frying.
- 1 cup buttermilk: Acts as a marinade to soften the onions and adds a subtle tang to complement the coating.
- 1 cup all-purpose flour: Creates the first dry layer that helps the coating stick better.
- 1 cup breadcrumbs (preferably panko): Panko breadcrumbs give these chips a light, airy crunch that’s hard to beat.
- 1 cup grated Parmesan cheese: Adds an irresistible savory richness and helps to brown the coating beautifully.
- 1 teaspoon garlic powder: Infuses an aromatic depth without overpowering the onion’s natural flavor.
- 1 teaspoon onion powder: Amplifies the onion presence in every bite.
- 1 teaspoon paprika: Provides a subtle warmth and a lovely color to the coating.
- 1/2 teaspoon black pepper: Adds a mild heat and layers of flavor complexity.
- 1/2 teaspoon salt: Essential for seasoning and bringing out the natural sweetness of the onions.
- Vegetable oil, for frying: Use an oil with a high smoke point to ensure crispy, perfectly fried onion chips.
How to Make Crispy Parmesan Onion Ring Chips Recipe
Step 1: Prepare the Onion Rings
Begin by slicing your onions into thin rings, about a quarter of an inch thick. Gently separate these rings and set them aside. This thickness is just right to achieve that crisp finish while maintaining some tender bite inside.
Step 2: Soak in Buttermilk
Place the onion rings in a bowl and pour the buttermilk over them until they are fully coated. Let them soak for at least 30 minutes to tenderize the onions and enhance their flavor. This little step makes a big difference by softening the raw sharpness and allowing the coating to adhere better.
Step 3: Mix the Flour and Spices
While the onions soak, combine the flour, garlic powder, onion powder, paprika, black pepper, and salt in a shallow dish. This seasoned flour mixture is the first layer of dry coating that ensures the buttermilk sticks perfectly in the next step.
Step 4: Combine Breadcrumbs and Parmesan
In another shallow dish, thoroughly mix the panko breadcrumbs with the grated Parmesan cheese. This mixture will form the final, crunchy crust that delivers mouthwatering crispness and cheesy goodness with every bite.
Step 5: Heat the Oil
Heat vegetable oil in a deep skillet or frying pan over medium heat until it reaches around 350°F (175°C). Maintaining the right temperature is key to frying that crisp coating without absorbing too much oil.
Step 6: Coat the Onion Rings
Remove your onion rings from the buttermilk, letting any excess drip off. First, dredge each ring in the seasoned flour mixture ensuring every ring is fully coated. Then dip it back briefly into the buttermilk before finally rolling the ring thoroughly in the breadcrumb and Parmesan mixture. This double coating method creates a thick, crunchy shell.
Step 7: Fry to Golden Perfection
Carefully place the coated onion rings into the hot oil without crowding the pan. Fry them in batches for about 2-3 minutes per side, turning once, until they are gorgeously golden brown and irresistibly crisp.
Step 8: Drain and Repeat
Remove fried onion ring chips with a slotted spoon and place them on a paper towel-lined plate to absorb any excess oil. Repeat the frying process until all of the onion rings have been cooked to crispy perfection.
Step 9: Serve Immediately
Serve your crispy Parmesan onion ring chips hot as a crowd-pleasing snack or as an indulgent side. They’re best enjoyed fresh, delivering that perfect crunch with every bite.
How to Serve Crispy Parmesan Onion Ring Chips Recipe

Garnishes
A sprinkle of freshly chopped parsley or a dusting of additional grated Parmesan can add a burst of color and a touch of fresh, bold flavor. A pinch of smoked paprika sprinkled on top can also enhance their smoky notes.
Side Dishes
These onion ring chips pair beautifully with classic dips like ranch, spicy ketchup, or a cool garlic aioli. They also make a fantastic side for burgers, grilled sandwiches, and even fried chicken, adding texture and cheesy flair.
Creative Ways to Present
For a fun twist, serve these chips stacked in a cone-lined basket, perfect for parties or casual gatherings. You can also layer them over fresh salads for added crunch, or scatter them atop mac and cheese for an irresistible topping that brings extra texture and flavor.
Make Ahead and Storage
Storing Leftovers
If you have any leftover crispy Parmesan onion ring chips, store them in an airtight container at room temperature for a few hours, but avoid refrigerating as it can make them soggy. Use within the same day to keep that delightful crunch.
Freezing
While freshly fried chips are best, you can freeze the coated but unfried onion rings. Lay them out in a single layer on a tray, freeze until solid, then transfer to a freezer-safe bag. When ready, fry them from frozen for a crispy snack anytime.
Reheating
To revive the crispiness, reheat leftover or frozen-fried chips in a hot oven or air fryer rather than the microwave. This helps to bring back their golden, crunchy texture without making them greasy or limp.
FAQs
Can I bake the Crispy Parmesan Onion Ring Chips Recipe instead of frying?
Yes! For a healthier twist, bake them on a greased baking sheet at 400°F for about 15-20 minutes, flipping halfway through. While they won’t be quite as crispy as fried, the Parmesan and panko still create a delicious crust.
What type of onions work best for this recipe?
Yellow onions are classic for their balance of sweetness and pungency, but sweet onions like Vidalia also work wonderfully if you prefer a milder flavor. Just be sure to slice them evenly for consistent cooking.
Can I use gluten-free flour and breadcrumbs?
Absolutely! Substitute with your favorite gluten-free flour and gluten-free panko breadcrumbs to accommodate dietary preferences without sacrificing texture or taste.
How do I know when the oil is at the right temperature?
Using a kitchen thermometer is best to maintain around 350°F (175°C). If you don’t have one, test by dropping a small bit of batter into the oil—if it sizzles and rises to the surface quickly, the oil is ready for frying.
Can I prepare the onion rings in advance?
You can slice and soak the onions ahead of time and keep them refrigerated in buttermilk for up to a few hours. However, coat and fry them just before serving for the crispiest results.

Instructions
- Slice onions: Slice the onions into thin rings about 1/4 inch thick. Carefully separate the rings from each other and set aside to prepare for soaking.

- Prepare flour seasoning: In a shallow dish, mix together the all-purpose flour, garlic powder, onion powder, paprika, black pepper, and salt until evenly combined.

Notes
- For extra crispiness, use panko breadcrumbs as they provide a lighter and crunchier texture.
