Crispy Fried Baby Bloomin Onions with Buttermilk Coating

These miniature bloomin' onions transform small cipollini onions into crispy, golden appetizers with perfectly separated petals. Each onion is carefully cut to create flower-like layers, then double-coated in seasoned flour and buttermilk for maximum crunch. The result is a bite-sized version of the restaurant favorite that's perfect for parties, game day, or any gathering where you want impressive finger food. The smoky paprika and garlic powder in the coating add depth while the buttermilk creates an extra-crispy exterior that contrasts beautifully with the sweet, tender onion inside.

Tip 1

Keep oil temperature steady at 350 degrees for even cooking and proper crisping without burning the coating.

Tip 2

Don't skip the double coating process as it creates the signature thick, crunchy exterior that mimics restaurant-style bloomin onions.

Tip 3

Gently separate onion layers after cutting to ensure they bloom properly during frying and create the classic flower appearance.

FAQ

Can I bake these instead of frying?

Yes, bake at 425F for 15-20 minutes, turning once. Spray with oil for better browning, though texture won't be as crispy as fried version.

What if I can't find cipollini onions?

Use small yellow onions about 2 inches in diameter. Pearl onions work too but may be harder to cut evenly without falling apart.

How long do these keep and can I reheat them?

Best eaten immediately. Can store in fridge 2 days and reheat in 400F oven for 5 minutes to restore some crispness.
