1 large sweet onion (Vidalia preferred): The star of the show. Sweet onions provide the perfect balance of sweetness and structure for slicing into a “bloom.”

1 ½ cups all-purpose flour: The foundation for a crispy coating.

1 tablespoon paprika: Adds smoky flavor and a rich color.

1 tablespoon garlic powder: Delivers bold, savory depth.

1 teaspoon onion powder: Reinforces the onion flavor in every bite.

1 teaspoon salt: Enhances overall flavor.

1 teaspoon black pepper: Adds mild heat.

½ teaspoon cayenne pepper (optional): For an extra kick.

🥚 For the Egg Wash:

2 large eggs: Helps the breading adhere to the onion.

1 cup milk (or buttermilk): Adds richness and smooth texture to the coating process.

🧴 For the Dipping Sauce:

½ cup mayonnaise: The creamy base.

2 tablespoons ketchup: Adds sweetness and tang.

2 tablespoons horseradish (prepared): Brings the heat and zip.

½ teaspoon paprika: Adds warmth and smokiness.

¼ teaspoon salt: Balances the flavors.

¼ teaspoon black pepper: For depth.

Pinch of cayenne pepper: Gives it that signature zing.

👨‍🍳 Step-by-Step Instructions

🔪 Step 1: Prepare the Onion Bloom

1. Cut off ½ inch from the pointy stem end of the onion (leave the root end intact).

2. Peel off the skin.

3. Place onion root-side down on a cutting board. Starting ½ inch from the root, make 4 even cuts downwards like slicing a pie.

4. Then make 3 more sets of cuts between the previous ones to create 16 "petals."

5. Carefully separate the layers without breaking.

> 💡 Pro Tip: Soak the cut onion in cold water for 1 hour to help it open up more fully and improve crispiness.

3. Return to the flour mixture for a second coating.

🧠 Pro Tips for Perfecting Your Bloomin’ Onion

Use a sweet onion for the best flavor.

Double-dip for a thicker, crunchier crust.

Refrigerate the onion for 30 minutes after breading to help the coating stick better.

Avoid overcrowding the fryer, or the oil temperature will drop and make it soggy.

Do not microwave leftovers. Use an oven or air fryer at 375°F for 8–10 minutes.

---

✅ Storage & Reheating

Store: In an airtight container for up to 2 days.

Reheat: Use an oven or air fryer for crispiness. Avoid microwaving to prevent sogginess.
