Essential Ingredients for Perfect Onion Rings
The key to exceptional homemade onion rings starts with selecting quality ingredients that work together to create the ideal texture and flavor.
Main Ingredients:
- 2 medium sweet onions (yellow varieties work best)
- Vegetable oil for deep frying
- 1 cup all-purpose flour
- 3 tablespoons cornstarch
- 1 large egg
- 1/2 cup milk
Seasonings for Flavor:
- 1 1/2 teaspoons salt
- 1/2 teaspoon baking powder
- 1/2 teaspoon garlic powder
- 1/2 teaspoon paprika
Sweet onions like Vidalia or Walla Walla varieties provide the best results due to their mild flavor and natural sweetness. The cornstarch addition creates extra crunch, while baking powder helps the batter puff up for a lighter coating.

- Heat 1 1/2 inches of oil to 375°F in a large pot

Why This Recipe Works
This homemade onion rings recipe succeeds because it combines the right ingredients in proper proportions with correct cooking technique for consistently crispy results.
The cornstarch and flour combination creates a light, crunchy coating that doesn’t become heavy or greasy. Baking powder adds lift to the batter, while the milk and egg provide binding without weighing down the mixture.
Temperature control ensures the coating crisps quickly while the onions cook to tender perfection inside. This balance creates the ideal contrast of textures that makes great onion rings irresistible.
With practice, you’ll master this technique and never need to rely on frozen onion rings again. Fresh, homemade rings offer superior flavor and texture that’s worth the small effort required.

Crispy Homemade Onion Rings
Ingredients
Equipment
Method
- Peel the onions but leave them whole. Slice each onion crosswise into rings that are about ¼ inch thick. Separate the rings carefully.
- In a 5-quart pot or Dutch oven, heat 1½ inches of oil over medium heat until a candy thermometer registers 375°F. Line a sheet tray with paper towels, then place a wire rack inside.
- In a large mixing bowl, whisk together the flour, cornstarch, salt, baking powder, garlic powder, and paprika until well combined.
- In a large liquid measuring cup, whisk the milk, ½ cup cold water, and egg until fully combined and smooth.
- When the oil is nearly at 375°F, whisk the cold liquid mixture into the flour mixture until no lumps remain and the batter is smooth.
- Once the oil is hot, place a few onion slices into the batter and turn until well-coated. With a fork, remove each ring, letting the excess drip off, then carefully place it in the hot oil.
- Continue working in batches to dip and fry the onion slices for 2 to 3 minutes, flipping occasionally until golden brown and crispy. Adjust the heat as needed to maintain the oil’s temperature between 350 and 375 degrees.
- Remove the onion rings from the oil using a spider strainer or large slotted spoon and place them on the wire rack to drain. Sprinkle with more salt to taste and serve immediately.
Notes
- Temperature Control: Use a candy thermometer for accurate oil temperature. Maintain between 350-375°F for best results.
- Batter Tips: If the batter is too thin and does not coat the onions well, whisk in 1 more tablespoon of cornstarch.
- Flavor Variation: Use seasoned salt in place of regular salt for added flavor.
- Storage: Best served immediately, but leftovers can be reheated in a 400°F oven for 5-7 minutes.
- Oil Safety: Never leave hot oil unattended and keep a lid nearby in case of splattering.
