Ingredients

For the Bloomin’ Onion

• 1 large sweet onion (such as Vidalia)
• 2 cups all-purpose flour
• 1 tablespoon paprika
• 1 teaspoon cayenne pepper
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• ½ teaspoon salt
• ½ teaspoon black pepper
• 2 large eggs
• 1 cup whole milk
• Vegetable oil (for frying)

For the Dipping Sauce

• ½ cup mayonnaise
• 2 tablespoons ketchup
• 1 tablespoon prepared horseradish
• ½ teaspoon paprika
• ¼ teaspoon salt
• ¼ teaspoon black pepper
• ¼ teaspoon cayenne pepper

 

 

Step-by-Step Instructions

Step 1 – Prepare the Onion
Peel the onion and trim the top (leaving the root end intact). Place root-side down, then make 16–20 vertical cuts from top to bottom, stopping ½ inch before the root. Gently separate the onion petals.

Step 2 – Make Dredging Stations
In a large bowl, whisk flour with paprika, cayenne, garlic powder, onion powder, salt, and pepper. In a separate bowl, whisk together eggs and milk until smooth.

Step 3 – Coat the Onion
Dip the onion into the flour mixture, coating every petal. Shake off excess, then dip into the egg mixture, followed by a second coating of flour.

Step 4 – Heat Oil & Fry
Heat oil in a deep fryer or heavy pot to 375°F (190°C). Carefully lower the onion into the oil, root-side up, and fry for 5–7 minutes until golden brown. Remove and drain on paper towels.

Step 5 – Make the Sauce & Serve
Mix mayonnaise, ketchup, horseradish, paprika, salt, pepper, and cayenne until smooth. Serve warm with the crispy onion for dipping.

FAQs

1. Can I make this ahead of time?
It’s best served immediately, but you can prep the onion up to the dredging step and refrigerate before frying.

2. What oil works best?
Vegetable oil, canola oil, or peanut oil are best for high-heat frying.

3. Can I bake instead of frying?
Yes—though it won’t be quite as crispy. Brush with oil and bake at 400°F until golden.

4. What’s the best onion to use?
Vidalia or other sweet onions are ideal since they balance out the spice.

5. Is the sauce spicy?
It has a mild kick from horseradish and cayenne, but you can adjust heat to taste.
