Crispy and delicious, onion rings are a classic snack or side dish that everyone loves. This easy-to-make batter recipe ensures that your onion rings come out perfectly golden and crunchy every time. Whether you're serving them at a party or enjoying them as a treat, these onion rings are sure to be a hit.
Most of the ingredients for this recipe are common pantry staples. However, if you don't usually keep baking powder on hand, make sure to pick some up at the supermarket. It's essential for giving the batter a light and airy texture. Additionally, ensure you have fresh milk and a beaten egg for the best results.

Ingredients For Onion Ring Batter Recipe
Flour: The base of the batter, providing structure and thickness.
Baking powder: Helps the batter rise and become light and crispy.
Salt: Enhances the flavor of the batter and the onion rings.
Milk: Adds moisture and helps create a smooth batter.
Egg: Binds the ingredients together and adds richness to the batter.
Technique Tip
To achieve a perfectly crispy texture, ensure the oil is at the right temperature before frying. Use a thermometer to maintain the oil at around 350°F (175°C). If the oil is too cool, the batter will absorb more oil and become greasy. If it's too hot, the batter will burn before the onion rings are fully cooked.
Suggested Side Dishes
Alternative Ingredients
all-purpose flour - Substitute with rice flour: Rice flour provides a similar texture and is gluten-free, making it suitable for those with gluten sensitivities.
all-purpose flour - Substitute with cornstarch: Cornstarch creates a lighter and crispier batter, ideal for achieving a crunchy texture.
baking powder - Substitute with baking soda and cream of tartar: Use ¼ teaspoon of baking soda and ½ teaspoon of cream of tartar to replicate the leavening effect of baking powder.
baking powder - Substitute with self-rising flour: Self-rising flour already contains baking powder and salt, so you can use it in place of both ingredients.
salt - Substitute with soy sauce: Soy sauce adds a similar salty flavor along with a bit of umami, enhancing the overall taste.
salt - Substitute with sea salt: Sea salt can be used in the same quantity and provides a slightly different mineral flavor.
milk - Substitute with buttermilk: Buttermilk adds a tangy flavor and helps create a tender batter.
milk - Substitute with almond milk: Almond milk is a dairy-free alternative that works well in batter recipes.
beaten egg - Substitute with flaxseed meal and water: Mix 1 tablespoon of flaxseed meal with 3 tablespoons of water to replace one egg, suitable for vegan diets.
beaten egg - Substitute with applesauce: Use ¼ cup of applesauce to replace one egg, adding moisture and a hint of sweetness.

How to Store or Freeze This Recipe
Allow the onion rings to cool completely before storing. This prevents condensation, which can make them soggy.
Place the cooled onion rings in an airtight container. Layer them with parchment paper to avoid sticking.
Store the container in the refrigerator if you plan to consume them within 2-3 days. For longer storage, place the container in the freezer.
To freeze the onion rings, arrange them in a single layer on a baking sheet lined with parchment paper. Freeze until solid, then transfer to a freezer-safe bag or container.
When ready to reheat, preheat your oven to 375°F (190°C). Place the onion rings on a baking sheet and bake for 10-15 minutes, or until heated through and crispy.
For best results, avoid microwaving as it can make the onion rings lose their crispiness.
How to Reheat Leftovers
Preheat your oven to 375°F (190°C). Place the onion rings on a baking sheet lined with parchment paper. Bake for about 10-15 minutes, turning halfway through, until they are crispy and heated through.
Use an air fryer for a quick and efficient method. Preheat the air fryer to 350°F (175°C). Arrange the onion rings in a single layer in the basket. Air fry for 5-7 minutes, shaking the basket halfway through to ensure even heating.
For a stovetop method, heat a skillet over medium heat and add a small amount of vegetable oil. Once the oil is hot, add the onion rings in a single layer. Fry for 2-3 minutes on each side until they are crispy and warmed through.
If you're in a pinch, the microwave can be used, though it may not retain the crispiness. Place the onion rings on a microwave-safe plate lined with a paper towel. Microwave on high for 20-30 seconds, checking frequently to avoid overcooking.
