Ingredients
For the Onion:
- 1 large sweet onion (such as Vidalia or Walla Walla)
- 2 cups (250g) all-purpose flour
- 2 teaspoons paprika
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon cayenne pepper (optional)
- 1 teaspoon salt
- ½ teaspoon black pepper
- 2 large eggs
- 1 cup (240ml) milk
For the Dipping Sauce:
- ½ cup (120g) mayonnaise
- 2 tablespoons ketchup
- 1 teaspoon prepared horseradish
- ½ teaspoon smoked paprika
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ¼ teaspoon cayenne pepper (optional)
- Salt and pepper to taste
For Frying:
- 4 cups (1 liter) vegetable oil (or enough to submerge the onion)
Step-by-Step Instructions
Step 1: Prepare the Onion
- Cut off ½ inch from the pointy end of the onion (not the root) and peel off the outer skin.
- Place the onion root-side down on a cutting board. Using a sharp knife, make 16–20 cuts from the top of the onion down to the root, spacing them evenly to create petals. Be careful not to cut through the root.
- Gently separate the onion layers to “bloom” the petals, taking care not to break them.
Step 2: Make the Batter and Coating
- In a large mixing bowl, combine the flour, paprika, garlic powder, onion powder, cayenne pepper, salt, and black pepper.
- In a separate bowl, whisk together the eggs and milk to create the wet batter.
Step 3: Coat the Onion
- Place the onion in the flour mixture, ensuring the flour gets into all the layers. Shake off any excess.
- Dip the onion into the egg mixture, coating it thoroughly.
- Return the onion to the flour mixture for a second coating, making sure every petal is covered.
Step 4: Heat the Oil
- In a deep fryer or large heavy-bottomed pot, heat the vegetable oil to 375°F (190°C). Ensure there is enough oil to fully submerge the onion.
Step 5: Fry the Onion
- Carefully lower the coated onion into the hot oil, root-side up, using a slotted spoon or spider strainer. Fry for 7–10 minutes, or until golden brown and crispy.
- Remove the onion from the oil and drain on a plate lined with paper towels.
Step 6: Make the Dipping Sauce
- In a small bowl, mix together the mayonnaise, ketchup, horseradish, paprika, garlic powder, onion powder, cayenne pepper, salt, and pepper. Adjust seasonings to taste.
Step 7: Serve and Enjoy
- Place the blooming onion on a serving platter and serve warm with the dipping sauce in the center or on the side.
Ingredient Background
- Sweet Onion: Sweet onions, like Vidalia or Walla Walla, have a mild flavor that works perfectly for frying.
- Seasoning Blend: Paprika, cayenne, and garlic powder add depth and a touch of heat to the batter.
- Dipping Sauce: The tangy and slightly spicy sauce complements the crispy onion beautifully.
Technique Tips
- Cutting the Onion: Use a very sharp knife to make clean, even cuts for a well-bloomed onion.
- Coating the Onion: Ensure each petal is well coated with flour and batter for maximum crunch.
- Oil Temperature: Maintain an oil temperature of 375°F (190°C) for even cooking and a crispy exterior.
Alternative Presentation Ideas
- Blooming Onion Rings: Instead of a full onion, cut into thick rings and follow the same battering and frying process.
- Mini Blooming Onions: Use smaller onions for individual servings.
- Baked Blooming Onion: For a healthier option, bake the coated onion at 400°F (200°C) for 20–25 minutes.
Additional Tips for Success
- Avoid Overcrowding: Fry one onion at a time to ensure even cooking.
- Keep it Crisp: Serve immediately after frying to enjoy the crispiness at its peak.
- Season to Taste: Adjust the spice level in the batter and sauce to suit your preference.
Recipe Variations
- Spicy Blooming Onion: Add extra cayenne or chili powder to the batter and dipping sauce for more heat.
- Cheesy Blooming Onion: Sprinkle grated Parmesan or cheddar cheese over the onion immediately after frying.
- Herb-Infused Batter: Add dried herbs like oregano or thyme to the flour mixture for a unique flavor twist.
Freezing and Storage
- Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 2 days.
- Reheating: Reheat in an oven or air fryer at 375°F (190°C) for 5–7 minutes to restore crispiness.
- Freezing: The onion is best served fresh; freezing is not recommended as it may lose its texture.
Healthier Twist Ideas
- Baked Version: Bake instead of frying to reduce calories and fat content.
- Gluten-Free Batter: Use a gluten-free flour blend in place of all-purpose flour.
- Air Fryer Option: Cook in an air fryer at 375°F (190°C) for 15–18 minutes, spraying lightly with oil.
Serving Suggestions for Events
- Game Day Appetizer: Pair with wings, sliders, and nachos for a winning game-day spread.
- Family Gatherings: Serve alongside BBQ or grilled meats for a delicious side dish.
- Potluck Favorite: Bring a blooming onion as a centerpiece appetizer to wow the crowd.

Frequently Asked Questions
Q1: Can I use a regular onion instead of a sweet onion?
Yes, but sweet onions have a milder flavor that works best for this recipe.

Handle the onion gently and avoid over-separating the petals during preparation.
Q3: Can I make the batter ahead of time?
The dry and wet batters can be prepared ahead and stored separately. Combine just before coating.

Fry until golden brown, and ensure the oil temperature is consistent for even cooking.

Add extra cayenne or hot sauce to the sauce for an extra kick.
