Ingredients You’ll Need

Here’s everything you need to make mini blooming onions that are crispy, flavorful, and beautifully golden.

Tip: You’ll find the full list of ingredients and measurements in the recipe card below.

• 4 small onions
• 1 cup all-purpose flour
• 1 teaspoon paprika
• 1 teaspoon garlic powder
• 1 teaspoon salt
• ½ teaspoon black pepper
• 2 large eggs
• 1 cup buttermilk
• 1 cup breadcrumbs
• Cooking spray

Let’s Get Started

1. Prepare the Onions

Peel the onions and trim just enough off the top to create a flat surface. Keep the root end intact—this holds the onion together.
Place the onion root-side down and slice vertically, making 8–12 cuts (like cutting a pie) without slicing all the way through. Gently separate the layers into “petals.”

2. Create the Dry Coating

In a bowl, mix together the flour, paprika, garlic powder, salt, and pepper. This seasoned flour coats each petal and sticks to the onion beautifully.

3. Prepare the Wet Dip

In another bowl, whisk the eggs with the buttermilk until smooth.
The buttermilk adds tangy flavor and helps create a thick coating that the breadcrumbs cling to.

4. Coat the Onions

Dust each onion thoroughly in the flour mixture, spreading the petals apart so the coating reaches inside.
Next, dip into the egg-buttermilk mixture, letting excess drip off.
Finally, coat in breadcrumbs, again ensuring that the crumbs get between all the petals.

5. Preheat and Prep the Air Fryer

Preheat your air fryer to 375°F (190°C).
Spray the basket lightly with cooking spray to prevent sticking.

6. Air Fry Until Crisp

Arrange the coated onions in the air fryer basket in a single layer. Spray the tops lightly with cooking spray for extra crispiness.
Cook for 12–15 minutes, or until the onions are golden, crunchy, and tender on the inside.

7. Serve Hot

Remove from the air fryer and serve immediately with your favorite dipping sauces.

Storage Tips

While best eaten fresh, you can store leftover mini blooming onions.

Refrigerator

Store in an airtight container for up to 3 days.

Reheating

Air fryer: 350°F for 3–5 minutes
Oven: 375°F for 8–10 minutes
Avoid microwaving—it makes them soggy.

Freezing

Not recommended, as onions release moisture once thawed and coating becomes soft.

FAQs

How do I keep the petals from falling apart?

Leave the root end intact—this keeps the onion together as it blooms.

Can I use larger onions?

Yes, but cooking time will increase and coating may not crisp as evenly.

I don’t have buttermilk. What can I use?

Mix 1 cup milk + 1 tablespoon lemon juice or vinegar, let sit 5 minutes.

Can I make these without an air fryer?

Yes! Bake at 425°F (220°C) for 20–25 minutes, flipping halfway.

Why is my coating not sticking?

Make sure the onions are dry and coat them thoroughly with flour before dipping into the wet mixture.
