What You’ll Need

Gather your ingredients to create this crispy masterpiece. A large, sweet onion is key, along with a few pantry staples for the seasoned dredge and a rich, flavorful batter.

1 large sweet onion (Vidalia or colossal recommended)
For the dredge:
2 cups all-purpose flour
2 tsp salt
1 tsp black pepper
1 tsp paprika
1 tsp garlic powder
1/2 tsp cayenne pepper (optional)
For the batter:
1 1/2 cups all-purpose flour
1/2 cup cornstarch
1 tsp baking powder
1 tsp salt
1 tsp black pepper
1/2 tsp paprika
1/2 tsp garlic powder
1 cup milk (or buttermilk for extra tang)
1 large egg
1/4 cup water (or more, as needed)
4-6 cups vegetable oil (for frying)
For the dipping sauce (optional, but classic):
1 cup mayonnaise
1/4 cup ketchup
2 tbsp prepared horseradish
1 tsp Worcestershire sauce
1/2 tsp paprika
1/2 tsp garlic powder
Pinch of cayenne pepper
Salt and pepper to taste

Preparation Instructions

Follow these steps to craft a show-stopping Blooming Onion that rivals any restaurant version. The key is in the careful slicing and coating, ensuring every petal gets that perfect, crispy crust.

1. Prepare the Onion: Peel the onion and cut about 1/2 inch off the top, leaving the root intact. Place the onion root-side up. Using a sharp, sturdy knife, make 12-16 evenly spaced cuts from the top down to about 1/2 inch from the root, without cutting all the way through. Gently spread the “petals” apart to create the blooming effect.
2. First Dredge: In a large bowl, combine the 2 cups flour, 2 tsp salt, 1 tsp pepper, 1 tsp paprika, 1 tsp garlic powder, and 1/2 tsp cayenne (if using). Thoroughly coat the entire onion, ensuring the seasoned flour gets between all the petals. Shake off any excess flour.
3. Prepare the Batter: In another large bowl, whisk together the 1 1/2 cups flour, 1/2 cup cornstarch, 1 tsp baking powder, 1 tsp salt, 1 tsp pepper, 1/2 tsp paprika, and 1/2 tsp garlic powder. In a separate small bowl, whisk the milk and egg. Add the wet ingredients to the dry ingredients, along with 1/4 cup water, and whisk until smooth. The batter should be thick enough to coat, but pourable. Add more water if needed, a tablespoon at a time, to reach the desired consistency.
4. Batter the Onion: Submerge the floured onion into the prepared batter, ensuring every crevice is thoroughly coated. Use your hands to gently separate the petals and work the batter in. Lift the onion, allowing excess batter to drip off. For an extra crispy fried onion blossom, you can do a second light dredge in plain flour after the batter.
5. Heat the Oil: In a large, deep pot or Dutch oven, heat the vegetable oil to 350°F (175°C). Use a deep-fry thermometer to accurately monitor the temperature.
6. Fry the Onion: Carefully place the battered onion into the hot oil, cut-side down first, then flip after a few minutes to ensure even cooking. Fry for 8-12 minutes, or until golden brown and beautifully crispy, turning occasionally. If the onion starts to brown too quickly, reduce the heat slightly.
7. Drain: Carefully remove the fried onion from the oil and place it on a wire rack set over paper towels to drain any excess oil.
8. Prepare Dipping Sauce: While the onion fries, whisk together all dipping sauce ingredients (mayonnaise, ketchup, horseradish, Worcestershire, paprika, garlic powder, cayenne, salt, and pepper) in a small bowl. Adjust seasonings to taste.
9. Serve: Place the warm Blooming Onion on a serving platter with the dipping sauce in the center. Gently pull apart the petals for easy sharing and enjoyment.

Fun Twists & Serving Ideas

Elevate your Blooming Onion with these creative variations and serving suggestions:

1. Spicy Kick: Add an extra teaspoon of cayenne pepper to both the dredge and batter mixtures for a fiery bloom. A dash of hot sauce in the dipping sauce will complete the heat.
2. Cheesy Delight: After frying, sprinkle the hot blooming onion with a generous amount of freshly grated Parmesan or a blend of Mexican cheeses. The residual heat will melt it beautifully.
3. Herb Garden: Mix 1 tablespoon of dried Italian herbs or fresh chopped parsley into the batter for an aromatic twist.
4. Smoky BBQ Blossom: Replace a portion of the paprika with smoked paprika in both the dredge and batter. Serve with a smoky BBQ ranch dipping sauce.
5. Mini Blooms: For smaller gatherings or individual portions, use smaller onions (like Spanish or yellow onions) and create mini blooming onions. Adjust frying time accordingly.

FAQ

Q: Can I use a different type of onion?
A: While sweet onions like Vidalia or colossal are recommended for their mild flavor and large size, you can experiment with yellow onions for a stronger onion taste. Red onions might also work but will have a different color and flavor profile.

Q: What’s the best way to cut the onion without cutting all the way through?
A: Place the onion root-side up. Use a sharp, sturdy knife and make your cuts from the top down, stopping about 1/2 inch from the root. Imagine a small circle at the root end that you don’t want to cut through.

Q: How do I ensure the Blooming Onion gets crispy?
A: Several factors contribute to crispiness: ensuring the oil is at the correct temperature (350°F), a thick batter that fully coats the onion, and not overcrowding the pot during frying. A second light dredge in flour after battering can also enhance crispiness.

Q: Can I make this ahead of time?
A: A fried onion blossom is best served immediately after frying for maximum crispness. You can prepare the dipping sauce ahead of time, and even cut and dredge the onion, keeping it refrigerated for up to an hour before battering and frying.

Q: What if I don’t have a deep fryer?
A: A large, deep pot or Dutch oven works perfectly for deep-frying. Just be sure to use enough oil for the onion to be mostly submerged and use a thermometer to maintain a consistent oil temperature.

Recipe Note

For best results and easier handling, consider blanching your onion in boiling water for 1-2 minutes immediately after cutting and before coating. This helps soften the onion slightly, making the petals more pliable and preventing them from breaking during coating and frying.
