- 1 teaspoon paprika
- 1/2 teaspoon garlic powder
- 1/4 teaspoon cayenne pepper (optional for a kick)
- 1/2 teaspoon salt

Directions
- Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup.
- Peel the onion and slice off about 1/2 inch from the top, keeping the root intact. Place the onion root-side up.

- Gently spread the onion petals apart, letting them bloom.
- In a shallow bowl, whisk together flour, paprika, garlic powder, cayenne, salt, and black pepper.
- In another bowl, whisk the milk and egg until combined.
- Immerse the onion in the milk-egg mixture first, then coat it evenly in the flour mixture.
- Position the onion root-side down on the prepared baking sheet and drizzle with olive oil to encourage browning.
- Bake for 30-40 minutes, or until the onion is tender and crispy.
- While it bakes, prepare your dipping sauce by whisking together mayonnaise, ketchup, horseradish, paprika, garlic powder, and cayenne.
- Serve the blooming onion hot alongside your zesty dipping sauce.
Best ways to enjoy it
This blooming onion shines as a standalone snack, appetizer, or side dish, but don’t hesitate to get creative with your serving ideas! Pair it with a fresh salad for added crunch, or enjoy it alongside your favorite burgers for a truly unforgettable meal. You can also serve it at parties with other finger foods to create a delightful spread.
Storage and reheating tips
To keep your blooming onion fresh, store any leftovers in an airtight container in the refrigerator. It’s best enjoyed within 2-3 days. When reheating, you can place it back in a preheated oven at 350°F (175°C) for about 10-15 minutes to regain that crispy texture. Avoid microwaving, as that can make it soggy.
Helpful cooking tips
For an extra crispy finish, consider double-dipping the onion into the milk-egg mixture and flour before baking. This creates a thicker crust that crunches delightfully when you bite into it. Additionally, don’t rush the blooming process; gently separating the petals is key to achieving that iconic flower shape.
Creative twists
If you want to experiment with flavors, why not try incorporating different spices into the flour mixture? Smoked paprika or Italian seasoning can add delightful new dimensions. You can even top your blooming onion with shredded cheese during the last few minutes of baking for an irresistible cheese pull!
Common questions
What’s the best type of onion to use for blooming onion?
While yellow onions are traditional due to their sweetness and mild flavor, you can also use sweet onions, like Vidalia, for a sweeter taste.
Can I make this recipe gluten-free?
Absolutely! Just substitute the all-purpose flour with gluten-free flour, and you’ll still achieve that crispy exterior.
What can I use instead of mayonnaise in the dipping sauce?
If you’re looking for a lighter option, Greek yogurt works well in place of mayonnaise, offering a tangy flavor with fewer calories.
With these insights and the step-by-step guide, you’re ready to create your own oven-baked blooming onion. Enjoy the deliciousness while sharing it with family and friends!
