Crispy Garlic Paprika Onion Rings with Herb Aioli Dip Tips, FAQ & printable recipe

Tips for success

For the crispiest onion rings, don't skip the cornstarch—it's the key to a light, shattery crust. Also, make sure the oil is at the right temperature before you start.

If it's not hot enough, the batter will absorb oil and become heavy; if it's too hot, the outside will burn before the onion cooks. Use a thermometer to keep it steady at 375°F (190°C).

When dipping the rings, let the excess batter drip off for a few seconds. This prevents thick, doughy spots and ensures even cooking.

Work in small batches and avoid moving the rings too soon after adding them to the oil—let the batter set before turning. Season with salt immediately after frying while the rings are still hot, so it sticks.

Variations

• Spicy Sriracha Onion Rings: Add 1-2 teaspoons of sriracha or hot sauce to the batter for a spicy kick. Serve with a cooling ranch or blue cheese dip.
• Parmesan Herb Onion Rings: Mix 1/2 cup grated Parmesan cheese and 1 tablespoon dried Italian herbs into the dry ingredients. The cheese adds a savory, salty crunch.
• Beer-Battered Onion Rings: Replace the cold water with an equal amount of cold beer. The carbonation makes the batter even lighter and adds a subtle malty flavor.
• Gluten-Free Onion Rings: Use a 1:1 gluten-free all-purpose flour blend in place of the regular flour. Ensure the baking powder is gluten-free, and check the aioli for gluten if needed.

Storage and make-ahead

Fridge

Store leftover onion rings in an airtight container in the refrigerator for up to 2 days. Reheat in a 400°F (200°C) oven for 5-7 minutes to restore crispness.

Freezer

Freeze fried onion rings in a single layer on a baking sheet, then transfer to a freezer bag for up to 1 month.

Reheat

To reheat, place onion rings on a baking sheet and warm in a 400°F (200°C) oven for 5-7 minutes, or until crisp and heated through.

Onion rings are best enjoyed fresh, but leftovers can be stored in an airtight container in the refrigerator for up to 2 days.

To reheat, place them on a baking sheet in a 400°F (200°C) oven for 5-7 minutes until crisp. Avoid microwaving, as it will make them soggy.

You can slice the onions and soak them in water up to a day ahead; keep them in the refrigerator. The batter can be mixed a few hours ahead and refrigerated, but whisk it again before using. For the best texture, fry the rings just before serving.

Serving ideas

Serve the onion rings hot, piled on a platter with a bowl of garlic herb aioli in the center.

The contrast of the hot, crispy rings and the cool, creamy dip is irresistible. Add a sprinkle of flaky sea salt and a few fresh herbs for a finishing touch.

These onion rings are perfect as an appetizer for parties, game days, or as a side to burgers and sandwiches. They also pair well with a cold beer or a fizzy lemonade. Set them out while they're still warm—they won't last long.

Crispy Garlic Paprika Onion Rings with Herb Aioli Dip

Prep 15 minCook 15 minTotal 30 minServes 4

Ingredients

• 3 medium sweet onions
• 1 cup all-purpose flour
• 2 tbsp cornstarch
• 1 tsp baking powder
• 1 tbsp garlic powder
• 1 tbsp smoked paprika
• black pepper to taste
• salt to taste
• 2/3 cup cold water
• vegetable oil, for frying, to taste
• garlic herb aioli, for serving

Instructions

1. Slice the sweet onions into thick rings, about 1/2 inch wide. Separate the rings and place them in a bowl of cold water; let soak for 5 minutes, then drain and pat dry with paper towels. In a separate bowl, whisk together the flour, cornstarch, baking powder, garlic powder, smoked paprika, black pepper, and salt. Add the cold water and whisk until smooth and free of lumps. The batter should be thick enough to coat the back of a spoon.
2. Pour about 2 inches of vegetable oil into a large, heavy skillet or deep fryer. Heat over medium-high until a deep-fry thermometer registers 375°F (190°C). If you don't have a thermometer, drop a tiny bit of batter into the oil; it should sizzle and float to the surface immediately.
3. Dip each onion ring into the batter, letting the excess drip off. Use tongs to lower a few rings gently into the hot oil. Do not overcrowd the pan—work in batches of 4 to 5 rings depending on the size of your skillet.
4. Fry the onion rings for about 3 minutes, turning once halfway, until they are deep golden brown and blistered. Use tongs to transfer them to a paper towel-lined plate to drain. Repeat with the remaining rings, allowing the oil to return to 375°F (190°C) between batches.
5. Drain the fried onion rings on fresh paper towels and season with a little extra salt while still hot. Pile them on a serving platter and serve immediately with garlic herb aioli for dipping.
