How to Make Crispy Onion Rings?
The onion is sliced into thick rings, separated, and dredged in flour seasoned with baking powder, salt, and paprika. Milk, egg, pepper, and merkén are whisked into the remaining flour to make a batter, the rings are dipped and coated in breadcrumbs, and fried in oil at 170°C (338°F).

Homemade Crispy Onion Rings Recipe
Preparation: 30 minutes
Cooking: 15 minutes
Servings: 4
Ingredients
- 300 ml (1¼ cups) of whole milk
- 120 g (1 cup) of all purpose flour
- 2 large onions
- 1 large egg
- 1 teaspoon of baking powder
- 1 teaspoon of paprika
- 1 teaspoon of salt
- ½ teaspoon of pepper
- Vegetable oil for frying
- Breadcrumbs or panko
- Merkén, to taste
Instructions
- Peel and wash the onions. With a sharp knife, cut them crosswise into slices about 1 cm thick and carefully separate the rings without breaking them. In a medium bowl, mix the sifted flour, baking powder, salt, and paprika with your fingers.

- Coat the onion rings in the flour mixture, shake off the excess, and set aside. Add the milk, egg, pepper, and, if you like, merkén to the remaining flour and blend with a hand mixer until smooth and runny.

- Dip the onion rings in the batter, let the excess drip off, coat them in breadcrumbs, and set aside. In a large pot or fryer, heat enough oil to about 170°C (338°F) and carefully lower in the rings without overlapping.

- Fry for a couple of minutes until golden, turning if needed, and drain on paper towels. Serve right away with aioli, salsa golf, ketchup, or mayonnaise.
Additional Tips
Soak the onion first
Soak the rings in cold water or milk for 30 minutes before coating. It softens the onion slightly, tames its bite, and improves the texture.
Chill the coated rings
Refrigerate the breaded rings for 15 minutes before frying so the coating sets and stays crispier.
Make them in an air fryer
Spray the basket with oil, arrange the rings without overlapping, and cook at 200°C (392°F) for 10 to 12 minutes, turning halfway.

Frequently Asked Questions (FAQs)
1. Which onion is best?
Sweet onions or large white onions have fewer sulfur compounds and a milder flavor that turns sweet when fried.
Panko is made from crustless bread dried into large, airy flakes, which gives a noticeably crunchier and lighter coating.
3. Why are my onion rings soft instead of crisp?
Usually because the oil was not hot enough, so the batter soaked up fat, or because too many rings were fried at once, lowering the oil temperature.
4. Can I use self rising flour?
Yes. It already contains a leavening agent, so leave out the teaspoon of baking powder.
