Key Ingredients for Deep Fried Onion Rings

See recipe card below for full list of measurements, ingredients, and instructions.

Sweet Yellow Onions

These are the star of the show! Sweet yellow onions provide just the right hint of natural sweetness and maintain their structure after frying. Slice them into thick, even rings for the best results. You can also use white onions for a sharper kick, or red onions for a beautiful color twist—just know the flavor will change a bit.

All-Purpose Flour

Flour forms the base of both the dredge and the batter, giving the onion rings their classic, crunchy crust. For an even crispier texture, you can replace up to 1/4 of the flour with cornstarch. Gluten-free flour blends work too, but the rings may be slightly less airy.

Cornstarch

A small amount of cornstarch in the batter makes the coating ultra-light and extra crispy. If you don’t have cornstarch, potato starch is a great substitute.

Club Soda

Club soda is the secret ingredient that gives the batter its signature lightness and bubbles, resulting in a delicate, tempura-style crust. Cold beer can be used instead for a deeper flavor—either way, make sure it’s extra cold!

Seasonings

A mix of salt, paprika, garlic powder, and black pepper brings out the savory notes and keeps every bite exciting. Feel free to adjust the seasonings or add a pinch of cayenne for heat!

Instructions for Deep Fried Onion Rings

See recipe card below for full list of measurements, ingredients, and instructions.

Slice the Onions

Peel the onions, then slice them into 1/2-inch thick rounds. Gently separate the slices into individual rings and set aside. Try to keep the rings similar in size so they cook evenly.

Prepare the Dredge and Batter

In one large bowl, whisk together 1 cup flour, cornstarch, 1 teaspoon salt, paprika, garlic powder, and black pepper. Remove 1/2 cup of this dry mixture and place it in a shallow dish for dredging. Add the remaining 1/2 cup flour and 1/4 teaspoon salt to a second shallow dish.

Pour the cold club soda (or beer) into the bowl with the remaining dry ingredients, whisking until just combined. Don’t overmix—it’s okay if the batter is a little lumpy.

Heat the Oil

Pour vegetable oil into a heavy-bottomed pot or deep fryer to a depth of about 2 inches. Heat the oil to 365°F (185°C). Use a thermometer for best results—this keeps the onion rings perfectly crisp and not greasy.

Dredge and Dip

Working in batches, dredge the onion rings in the plain flour, shaking off the excess. Next, dip each ring into the batter, letting the excess drip off.

Fry the Onion Rings

Carefully lower a few battered onion rings into the hot oil at a time. Fry for 2-3 minutes, turning once, until golden brown and crisp. Don’t overcrowd the pot—work in batches for best texture.

Drain and Season

Use a slotted spoon to transfer the fried onion rings to a paper towel-lined plate. Immediately sprinkle with a pinch of salt while they’re hot. Repeat with the remaining rings.

Recipe Variations

Make It Spicy

Love a little heat? Add 1/2 teaspoon cayenne pepper or a dash of hot sauce to the batter for a zesty kick that pairs perfectly with a creamy dip.

Gluten-Free Option

Swap out the all-purpose flour for your favorite gluten-free blend, and use gluten-free beer or sparkling water in place of club soda. The rings will still be crispy, but a touch lighter.

Buttermilk Twist

Soak the onion rings in buttermilk for 30 minutes before dredging and battering. This makes them even more tender and adds a tangy depth of flavor.

Beer-Battered Onion Rings

Substitute an ice-cold lager or ale for the club soda in the batter. This gives the coating a deep, malty richness and even crispier texture.

Panko-Crusted Crunch

For extra crunch, dip the battered rings in panko breadcrumbs before frying. The result is an ultra-crispy, restaurant-style onion ring.

Serving Suggestions

Deep Fried Onion Rings are perfect on their own, but even better alongside burgers, hot dogs, or grilled meats. Serve with classic ketchup, creamy ranch, spicy sriracha mayo, or even a tangy barbecue sauce for dipping. For a fun garnish, sprinkle with fresh chopped parsley or a dusting of smoked paprika right before serving.

Storage and Reheating

Store any leftover onion rings in an airtight container in the refrigerator for up to 3 days. To reheat, bake them in a single layer on a wire rack at 400°F (200°C) for 8-10 minutes until hot and crisp. Avoid microwaving—they’ll lose their crunch. Onion rings are best enjoyed fresh, but you can freeze them in a single layer for up to 2 months; reheat from frozen in the oven for best results.

Frequently Asked Questions About Deep Fried Onion Rings (FAQ)

Q: Can I make onion rings ahead of time?
A: These are best eaten fresh for maximum crispiness, but you can prep the onion rings and refrigerate them for up to 2 hours before frying.

Q: What’s the best oil for frying onion rings?
A: Use a neutral oil with a high smoke point—vegetable, canola, or peanut oil are all great choices.

Q: Why is my batter falling off the onions?
A: Make sure to dredge the onions in flour first and avoid excess moisture. Batter also sticks best if onions are at room temperature and the batter is cold.
