Ingredients Needed

To make these delicious mini blooming onions, you will need a few simple pantry staples. The key is choosing the right type of onion to get that perfect “bloom” shape.

The Onions

• Pearl Onions or Small Shallots: (1 lb) These work best for the “mini” effect. Shallots offer a slightly milder, sweeter flavor, while pearl onions are more traditional. Ensure they are peeled completely.

The Batter & Coating

• All-Purpose Flour: (1/2 cup) The base for our breading. For a keto version, you can substitute almond flour.
• Cornstarch: (2 tbsp) This is the secret ingredient for extra crispiness in the air fryer.
• Eggs: (2 large) Beaten well to help the breading stick.
• Panko Breadcrumbs: (1 cup) Panko is essential for that jagged, super-crunchy texture. Regular breadcrumbs will be too dense.

The Seasoning Mix

• Paprika: (1 tsp) Adds color and a subtle smokiness.
• Garlic Powder: (1 tsp) A must-have for savory onion recipes.
• Cayenne Pepper: (1/2 tsp) Optional, but recommended for a little kick.
• Salt & Black Pepper: To taste.
• Cooking Spray or Olive Oil: Essential for misting the onions in the air fryer to encourage browning.

Kitchen Equipment

• Air Fryer: Any standard basket-style or oven-style air fryer works.
• Sharp Paring Knife: Crucial for making precise cuts in the small onions.
• Three Shallow Bowls: For your dredging station (flour, egg, breadcrumbs).
• Cutting Board: A stable surface is necessary for safety.

Step-by-Step Instructions

Step 1: Prep the Onions

Peel the pearl onions or shallots. Slice off the top (the pointy end) to create a flat surface. Keep the root end intact—this is critical as it holds the “petals” together.

Step 2: The “Bloom” Cut

Place the onion root-side down. Using your sharp paring knife, make a cut from the top down toward the root, stopping about 1/4 inch before you hit the bottom. Rotate the onion 90 degrees and make another cut, forming a cross. If the onions are large enough, make two more diagonal cuts to create 8 sections. Gently use your fingers to separate the petals slightly.

Step 3: Set Up the Dredging Station

Bowl 1: Whisk together the flour, cornstarch, paprika, garlic powder, cayenne, salt, and pepper.
Bowl 2: Beat the eggs with a splash of water or milk.
Bowl 3: Place the Panko breadcrumbs.

Step 4: Coat the Onions

Take an onion and dredge it in the flour mixture. Make sure to get flour in between the petals (you can turn it upside down and tap it). Dip it into the egg wash, ensuring it is fully coated. Finally, roll it in the Panko breadcrumbs, pressing gently to adhere the crumbs to the petals.

Step 5: Air Fry

Preheat your air fryer to 375°F (190°C). Spray the basket with cooking oil. Place the onions in the basket, leaving space between them so air can circulate. Do not overcrowd. Spray the tops of the onions generously with oil spray—this helps eliminate white flour spots and makes them golden.

Step 6: Cook to Perfection

Air fry for 10-15 minutes. Halfway through, check on them and give them another light mist of oil if they look dry. They are done when the petals are splayed open, crispy, and deep golden brown.

Step 7: Serve Immediately

Remove carefully with tongs. Sprinkle with a little extra salt or fresh parsley if desired. Serve hot with dipping sauce.

Expert Tips for Success

Don’t Cut the Root: The most common mistake is cutting all the way through the onion. If you cut the root, the onion will fall apart into separate petals. You need that base to hold the flower shape.

Soak for Better Blooming: If your onions are very tight and hard to separate, you can soak the peeled onions in ice water for 30 minutes after cutting them. This helps the petals “bloom” open naturally. Just be sure to dry them thoroughly before breading.

The Oil Spray Matters: Unlike deep frying, the air fryer relies on the oil you spray on the food. If you see white flour spots after 5 minutes of cooking, spray those spots directly with oil.

Variation – Cheesy Blooms: For a decadent twist, sprinkle grated Parmesan cheese over the onions during the last 2 minutes of cooking.

• The Classic Bloom Sauce: Mix mayonnaise, ketchup, horseradish, paprika, and a pinch of cayenne.

Common Questions (FAQ)

Can I make these gluten-free?

Absolutely. Swap the all-purpose flour for a gluten-free 1:1 baking flour and use crushed gluten-free cornflakes or gluten-free Panko for the coating.

How do I reheat leftovers?

These are best eaten fresh, as onions can get soggy over time. However, you can reheat them in the air fryer at 350°F for 3-5 minutes to crisp them back up. Microwave reheating is not recommended as they will become mushy.

Can I freeze these?

Yes! You can prep and bread the onions, then freeze them on a baking sheet before transferring to a bag. You can air fry them straight from frozen; just add 3-5 minutes to the cooking time.
