Full Recipe:

Ingredients

For the Blooming Onion:

• 1 large sweet onion (Vidalia works best), peeled and root kept intact

• 2 cups all-purpose flour

• 2 tsp paprika

• 1 tsp garlic powder

• 1 tsp cayenne pepper (adjust to taste)

• 1 tsp kosher salt

• 1/2 tsp freshly ground black pepper

• 2 large eggs

• 1 cup whole milk (2% works in a pinch)

• Vegetable oil for deep frying (about 6 cups, at least 3 inches)

For the Dipping Sauce:

• 1/2 cup mayonnaise

• 2 tbsp ketchup

• 1 tbsp prepared horseradish (more if you like it spicy!)

• 1/2 tsp paprika

• 1/4 tsp garlic powder

• 1/4 tsp salt

Directions

1. Prepare the onion: Slice about 1/2 inch off the pointy top of the onion, leaving the root intact. Make 16-18 vertical cuts from top to root, without cutting through the root. Soak the onion in ice water for at least 30 minutes.

2. Make the coating: In one bowl, mix flour, paprika, garlic powder, cayenne, salt, and black pepper. In another bowl, whisk eggs and milk together.

3. Coat the onion: Dip the onion in the flour mixture, coating it thoroughly. Then dip it in the egg wash and coat again with the flour mixture. Ensure flour gets between the onion petals.

4. Heat oil and fry: Heat oil to 375°F in a deep fryer or large pot. Carefully lower the onion into the hot oil, root-side up, and fry for 3-4 minutes until golden brown. Flip halfway if needed. Drain on paper towels.

5. Make the dipping sauce: Combine all sauce ingredients in a bowl. Taste and adjust the horseradish for spiciness if desired.

6. Serve: Serve the blooming onion hot, with dipping sauce in the center.

Why This Homemade Blooming Onion is So Special

This blooming onion brings all the flavors and textures of the classic restaurant version without the need for professional equipment or complicated techniques. The crispy petals are coated in a flavorful seasoning blend that’s spicy, savory, and perfectly balanced. The deep-frying technique creates that irresistible crunch while keeping the onion tender on the inside.

The dipping sauce takes things to the next level with a tangy kick from the horseradish, balancing out the richness of the onion. It’s the perfect accompaniment, giving you that classic combo of crispy and creamy.

The Perfect Onion for Blooming

When choosing an onion for your blooming onion, it’s important to go for a large, sweet onion that can hold its shape when sliced and fried. Vidalia onions are an excellent choice because they are naturally sweet and have a mild flavor that complements the seasoning perfectly. The sweetness of the onion pairs beautifully with the savory batter, creating a nice balance of flavors.

When slicing the onion, the root must remain intact to allow the petals to stay together and bloom as it fries. This step is key to getting the signature look and texture of a blooming onion. Soaking the onion in ice water for at least 30 minutes helps the petals open up more easily when frying, ensuring the perfect “bloom.”

The Coating: Crispy and Flavorful

The key to a great blooming onion is the coating. A combination of flour, paprika, garlic powder, cayenne pepper, and salt creates a savory, slightly spicy crust that crisps up beautifully when fried. The paprika gives the coating a deep, smokey flavor, while garlic powder adds aromatic depth. The cayenne pepper adds a gentle heat that balances the sweetness of the onion.

The double-dipping technique—first in the seasoned flour, then in the egg wash, and then back into the flour—ensures a thick, even coating that crisps up nicely. It’s this layer of batter that gives the onion its crunchy texture and rich flavor.

Frying to Perfection

Frying the onion is where the magic happens. The oil needs to be at the right temperature (375°F) to ensure that the onion crisps up without absorbing too much oil. Vegetable oil works best for frying due to its high smoke point, allowing the onion to fry evenly and crisp up without burning.

When placing the onion in the hot oil, make sure to lower it carefully, root-side up, to avoid splashing hot oil. Frying the onion for 3-4 minutes creates a golden brown, crispy crust that encases the tender onion petals inside. If necessary, flip the onion halfway through to ensure even frying.

The Dipping Sauce: Tangy, Creamy, and Perfectly Spicy

The dipping sauce for your blooming onion is just as important as the onion itself. The mayonnaise forms the creamy base, while the ketchup adds a subtle tangy sweetness. Horseradish is the star ingredient, giving the sauce a sharp, spicy kick that complements the richness of the fried onion perfectly. You can adjust the amount of horseradish to suit your taste, depending on how spicy you like it.

With a sprinkle of paprika and garlic powder, the sauce is both creamy and flavorful, providing the perfect contrast to the crunchy onion. This sauce is easy to make and can be customized to suit your preferences.

Serving the Blooming Onion

Once the onion is fried to golden perfection, it’s time to serve! Carefully place the blooming onion on a platter and serve with the dipping sauce in the center. The crispy onion petals can be pulled off individually, making it a fun and interactive dish to share with others. It’s perfect for a snack, a fun party appetizer, or as a side dish to complement other savory meals.

The blooming onion is best served immediately while it’s still hot and crispy, so make sure to enjoy it fresh out of the fryer. If you have leftovers, store them in an airtight container and reheat in the oven to preserve the crunch.

This homemade blooming onion is not just a treat for the taste buds but a fun experience for everyone. It’s ideal for serving at parties, game days, or casual gatherings.
