Ingredients to Make Blooming Onions at Home

Creating an authentic blooming onion involves a few key components:

Onion:

• 1 large sweet onion (like Vidalia or Walla Walla)

Batter:

• 1½ cups all-purpose flour

• 1 tsp paprika

• ½ tsp garlic powder

• ½ tsp salt

• ½ tsp pepper

• 1 cup milk

• 1 large egg

Dipping Sauce:

• ½ cup mayonnaise

• 2 tbsp ketchup

• 2 tsp horseradish

• ¼ tsp paprika

• ¼ tsp garlic powder

• Salt and pepper to taste

How to Make Blooming Onions – Step-by-Step

1. Prep the Onion

• Cut ½ inch off the top (pointed end) of the onion, leaving the root intact.

• Peel the skin and place root-side down.

• Make downward cuts all around the onion (12–16 cuts), stopping about ½ inch from the root.

• Soak in ice water for 30 minutes to help petals open.

2. Make the Batter

• In one bowl, combine flour, paprika, garlic powder, salt, and pepper.

• In a separate bowl, whisk milk and egg.

3. Batter and Coat

• Shake excess water from the onion and dip it in the flour mix.

• Then dip into the egg mixture, ensuring all petals are coated.

• Return to the flour mix for a final dredge, spreading petals to get flour between each layer.

4. Fry to Golden Perfection

• Heat oil to 375°F (190°C) in a deep fryer or large pot.

• Lower the onion, root-side up, into the oil and fry for 6–8 minutes until golden.

• Drain on paper towels and serve immediately.

Tips for the Best Blooming Onion Results

• Use sweet onions for the best flavor and shape.

• Maintain oil temperature to avoid soggy texture.

• Soak the onion in ice water to help it “bloom” beautifully.

• Serve immediately to retain crispness and flavor.
