How to Make Best Ever Blooming Onion

Step 1: Prepare and Cut the Onion

Start by peeling the onion, then slice off the top so it can stand upright. Carefully make 12 to 16 cuts from the top toward the root, keeping the root intact to hold the “petals” together. Gently spread the petals apart to create the blooming effect.

Step 2: Soak the Onion

Place the cut onion in a bowl of ice water for at least 30 minutes. This step helps the petals open further and firms them up, which results in a better frying texture.

Step 3: Prepare the Batter and Dipping Sauce

While the onion soaks, mix the flour, paprika, garlic powder, cayenne pepper, salt, and pepper in one bowl. In another, whisk the eggs with buttermilk. For the sauce, combine mayonnaise, ketchup, Worcestershire sauce, and a pinch of paprika and cayenne.

Step 4: Coat the Onion

Drain and carefully dry the onion petals. Dip the entire onion into the egg mixture, making sure to get between the petals, then dredge thoroughly in the seasoned flour mixture. Repeat the egg and flour coating for extra crispiness.

Step 5: Deep Fry

Heat vegetable oil to 375°F (190°C) in a deep fryer or large pot. Fry the coated onion for 3 to 5 minutes or until golden brown and crisp. Carefully remove and drain on paper towels.

Step 6: Serve Hot and Enjoy

Place your Best Ever Blooming Onion on a serving plate with a bowl of the dipping sauce. It’s best enjoyed while still warm to savor the full crispy crunch and fresh flavors.

Pro Tips for Making Best Ever Blooming Onion

• Choosing the Right Onion: Large sweet onions like Vidalia or Walla Walla work wonderfully for their size and mild flavor.
• Patience with Cutting: Take your time slicing the onion to prevent cutting through the root, which would cause the petals to fall apart.
• Double Dipping for Crunch: Coating the onion twice in egg and flour mixture ensures an extra crunchy and flavorful crust.
• Oil Temperature Matters: Maintain a consistent frying temperature for even cooking and to avoid greasy results.
• Serve Immediately: The blooming onion tastes best fresh out of the fryer for optimal crunch and flavor.

How to Serve Best Ever Blooming Onion

Garnishes

Sprinkle freshly chopped parsley or chives over the blooming onion for a pop of color and a gentle herbal note that enhances the visual appeal and taste profile.

Side Dishes

This blooming wonder pairs beautifully with crisp green salads, creamy coleslaw, or even loaded fries. Adding a fresh vegetable side can balance out the indulgent crispy onion.

Creative Ways to Present

Serve the onion on a rustic wooden board surrounded by small ramekins of varied dipping sauces like spicy ranch, garlic aioli, or zesty barbecue for a fun, interactive appetizer experience.

Make Ahead and Storage

Storing Leftovers

If you have any leftover blooming onion, store it in an airtight container in the refrigerator for up to 2 days, but keep in mind the crunchiness does diminish over time.

Freezing

While freezing is possible, it’s not recommended if you want to maintain the crisp texture; however, you can freeze battered onion petals before frying and cook them fresh later.

Reheating

To revive leftover blooming onion, reheat in a preheated oven at 375°F (190°C) on a wire rack for 10-15 minutes to regain crispiness without sogginess.

FAQs

What type of onion is best for a blooming onion?

Large and firm onions like yellow, Vidalia, or sweet onions work best because they hold their shape well and provide a balanced flavor that becomes sweet when fried.

Can I bake the blooming onion instead of frying?

Yes, baking is a healthier alternative; however, it won’t be as crispy as frying. Coat the onion well and bake at 425°F (220°C) for around 40 minutes, flipping halfway through.

How do I prevent the onion petals from falling apart?

The key is to slice carefully without cutting through the root end and soaking the onion in ice water to help the petals open while retaining structure.

What dipping sauce goes best with a blooming onion?

A classic creamy sauce made from mayo, ketchup, Worcestershire sauce, and spices complements the crispy onion beautifully, but ranch or spicy aioli also work great.

Is the Best Ever Blooming Onion very spicy?

The heat level is mild by default, thanks to a balanced touch of cayenne and paprika, but you can easily adjust the spice to suit your preference.
