What Ingredients You Will Need
This crispy onion rings recipe uses honest, everyday ingredients that come together for a bold flavor and that addictive crunch. You won’t need anything fancy, and most swaps work just fine if you’re missing something.
- For the Onion Rings:
- 2 large sweet onions, peeled and sliced into ½-inch (1.3 cm) rings (Vidalia or Walla Walla are great, but yellow onions work too)
- 1 ½ cups (190 g) all-purpose flour (for the batter)
- ½ cup (60 g) cornstarch (for extra crunch)
- 1 ½ tsp baking powder (helps make the batter airy)
- 1 tsp salt (plus more for seasoning)
- ½ tsp black pepper
- 1 tsp paprika (adds warmth and color)
- 1 ¼ cups (300 ml) cold sparkling water (or water; sparkling gives a lighter texture)
- Vegetable oil for frying (canola or peanut are my favorites)
- For the Spicy Ketchup:
- ½ cup (120 g) ketchup
- 1–2 tsp sriracha (adjust to your spice level)
- ½ tsp smoked paprika
- ½ tsp garlic powder
- Dash of hot sauce (optional, for extra heat)
- Pinch of sugar (balances the heat)
Ingredient tips: For best crunch, use fresh cornstarch and flour (I like King Arthur brand for consistency). If you want gluten-free, swap out the all-purpose flour for a gluten-free blend (Bob’s Red Mill works well). If you’re dairy-free, good news—there’s no milk in this batter. For a milder ketchup dip, use less sriracha or swap with your favorite mild chili sauce. In summer, I sometimes add a dash of lemon juice to the ketchup for brightness.
Substitutions: If you’re out of sweet onions, yellow or even red onions work (just expect a slightly sharper flavor). Sparkling water makes the batter extra light, but tap water works in a pinch. For a paleo option, try almond flour and arrowroot instead of flour and cornstarch. The recipe is pretty forgiving, and honestly, I’ve swapped a thing or two when I was knee-deep in snack mode!
Equipment Needed
Let’s talk kitchen tools—because the right equipment makes all the difference for crispy onion rings.
- Large heavy-bottomed pot or deep fryer (for safe, even frying)
- Slotted spoon or spider strainer (to lift out the rings without splashing hot oil)
- Mixing bowls (one for batter, one for dredging)
- Whisk (to get the batter smooth)
- Paper towels or wire rack (for draining the rings—wire rack keeps them crispy!)
- Sharp knife (for slicing onions evenly)
- Cutting board
- Measuring cups and spoons
Honestly, I’ve made these with everything from a Dutch oven to a cheap thrift-store fryer—they all work, just keep an eye on oil temperature. If you don’t own a wire rack, paper towels do the trick (just don’t stack the rings too close or they’ll steam). For mixing, any sturdy bowl works, but glass is easiest for cleanup. Maintenance tip: If you use a deep fryer, make sure to clean the basket after each batch—the batter bits love to stick! And budget-friendly? Most of these tools are already in your kitchen, so you’re good to go.
Preparation Method

Ready for the crunch? Here’s how to make crispy onion rings with spicy ketchup, step by step.
- Prep the onions: Peel and slice the onions into ½-inch (1.3 cm) thick rings. Gently separate the rings and set aside. (Tip: Discard the smallest inner rings—they tend to burn quickly.)
- Set up your frying station: Pour vegetable oil into a heavy-bottomed pot or deep fryer until it’s 2 inches (5 cm) deep. Heat to 350°F (175°C). (If you don’t have a thermometer, drop a tiny bit of batter in—if it sizzles and floats, you’re ready.)
- Make the batter: In a large mixing bowl, whisk together the flour, cornstarch, baking powder, salt, black pepper, and paprika. Pour in the cold sparkling water and whisk until smooth; batter should be thick but pourable. (If it’s too thick, add a splash more water.)
- Dredge the onion rings: Lightly dust onion rings with a bit of flour (helps batter stick). Dip each ring into the batter, coating evenly. (Tip: Hold the ring over the bowl for a second to let excess batter drip off.)
- Fry the onion rings: Carefully place battered rings into hot oil, working in batches so you don’t crowd the pot. Fry for 2–3 minutes per batch, turning once, until golden and crisp. (Sensory cue: They’ll float and turn deep golden brown, and the sizzle will sound “happy”—not angry.)
- Drain and keep warm: Use a slotted spoon to lift out the rings and place them on a wire rack or paper towels. Sprinkle with a little extra salt while hot. (Warning: Don’t stack them, or they’ll lose crunch!)
- Make the spicy ketchup: Stir together ketchup, sriracha, smoked paprika, garlic powder, hot sauce (if using), and sugar in a small bowl. Taste and adjust heat to preference.
- Serve: Pile onion rings onto a platter and serve hot with spicy ketchup for dipping.
Troubleshooting: If your rings turn greasy, your oil’s too cool. If the batter slides off, make sure onions are dry and batter isn’t too thin. For extra-crispy, double-dip: dredge in flour, then batter, then flour again before frying. Efficiency tip: Prep the ketchup while the rings fry, and keep finished rings in a warm oven if you’re making a big batch.
Cooking Tips & Techniques
Here’s what I’ve learned (the hard way) after frying more onion rings than I can count:
- Oil temperature matters: Keep it steady at 350°F (175°C). Too hot and the batter burns; too cool and the rings get soggy.
- Don’t crowd the pot: Fry in small batches so the oil stays hot and the rings cook evenly.
- Batter thickness: If the batter is too thin, add a touch more flour. Too thick? A splash of water fixes it.
- Dry onions are key: Dab slices with a paper towel before dipping. Wet onions can make the batter slide right off—learned that the messy way!
- Double-dipping: Want super crunch? Dust onions in flour, then batter, then a quick roll in flour again.
- Salt while hot: The rings soak up seasoning best right out of the oil.
- Multitasking: I like to whip up the spicy ketchup while the first batch fries—it saves time and makes serving seamless.
- Consistency: Use a kitchen thermometer if you can. It’s the best way to keep the oil at the right temp batch after batch.
I’ve had my share of soggy rings and burned batter. If you ever end up with limp onion rings, just check your oil temp and batter consistency. The best results come from staying patient and frying in batches. And honestly, don’t be afraid to taste test as you go—it’s all part of the fun!
Variations & Adaptations
Want to customize your crispy onion rings with spicy ketchup? Here are a few tried-and-true tweaks:
- Gluten-Free: Swap all-purpose flour for a gluten-free blend and use arrowroot instead of cornstarch. They’ll still turn out beautifully crisp.
- Spice Level: For milder rings, skip the paprika in the batter or use less sriracha in the ketchup. For extra heat, add cayenne to the batter or a pinch of chili flakes to your ketchup.
- Baked Version: Want to skip frying? Dip onion rings in batter, then coat with panko breadcrumbs and bake at 425°F (220°C) for 15–18 minutes, flipping halfway. (They’ll be lighter, but still tasty!)
- Seasonal Flavors: Add a dash of curry powder to the batter in winter, or mix in chopped fresh herbs like dill or parsley in summer.
- Allergen Substitutes: For egg-free, use aquafaba or a flaxseed “egg” for binding. Dairy-free? Luckily, no milk here!
My favorite twist is swapping out the ketchup entirely for a chipotle mayo when I want something smoky. You can also use red onions for a sharper bite, or even try beer in the batter for a deeper flavor. Honestly, the options are endless—and it’s all about what you’re in the mood for.
Serving & Storage Suggestions
Here’s how to serve and stash your crispy onion rings so they stay perfect:
- Serving: Serve hot, straight from the fryer, on a platter lined with parchment or in a basket for diner vibes. I like to pile them high and let people dig in! They’re best with spicy ketchup, but ranch, honey mustard, or chipotle mayo work too.
- Presentation: For Pinterest-worthy photos, stack rings in a tower or scatter a few on a wooden board with a bowl of dip in the center. Sprinkle with chopped parsley for color.
- Storage: Cool leftovers completely, then store in an airtight container in the fridge for up to 2 days. For longer storage, freeze on a baking sheet, then transfer to a zip-top bag—keeps for up to 1 month.
- Reheating: Reheat in a 400°F (200°C) oven for 8–10 minutes or in an air fryer at 375°F (190°C) for 5 minutes. Microwaving makes them soggy, so skip it if you can.
- Flavor notes: The crunch holds up best the day of, but the spicy ketchup actually gets tastier as it sits overnight.
Trust me, reheated onion rings in the oven still make a killer midnight snack. And if you’re prepping for a party, you can fry them ahead and crisp them up just before guests arrive.

Frequently Asked Questions
How do I keep my onion rings crispy after frying?
Place them on a wire rack instead of paper towels after frying. This lets air circulate and prevents sogginess. If you want to keep them warm, pop the rack in a low oven (200°F/95°C) until serving.
Can I make these crispy onion rings gluten-free?
Absolutely! Use a gluten-free flour blend in place of all-purpose flour, and swap cornstarch with arrowroot powder. You’ll still get a great crunch.
What’s the best onion type for this recipe?
Sweet onions like Vidalia or Walla Walla are my first pick—they’re mild and cook up tender. Yellow onions work too and give a stronger flavor.
Can I bake onion rings instead of frying?
Yes! Dip rings in batter, then coat with panko breadcrumbs. Bake at 425°F (220°C) for 15–18 minutes, flipping once. They’ll be lighter but still deliciously crispy.
How spicy is the ketchup dip?
The heat comes mostly from sriracha. Adjust the amount to your taste—start with 1 teaspoon for a mild kick, and bump it up if you want more spice. You can even use a mild chili sauce for less heat.
