Introduction
Mini Bloomin’ Onions are a fun and tasty twist on the classic steakhouse favorite. These crispy, bite-sized onions are perfectly seasoned and served with a creamy buttermilk ranch dip, making them an irresistible appetizer for any occasion.

Ingredients
- 16 cipollini onions
- 1 cup buttermilk
- 1 cup all-purpose flour
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon smoked paprika
- 1 teaspoon salt
- ½ teaspoon dry mustard
- ½ teaspoon black pepper
- Peanut or vegetable oil for frying
Instructions
- Step 1: Fill a tall pot with 2 ½ inches of oil and heat it to 350˚F.
- Step 2: Trim 1/8 inch from the pointed stem end of each cipollini onion. Peel carefully, taking care not to remove an entire layer.
- Step 3: Place each onion cut-side up and make a cross-cut through to the bottom stem, creating about 12 evenly spaced cuts. Turn over and gently separate the outer layers with your fingers.
- Step 4: Pour buttermilk into a small bowl and set aside. In another bowl, combine flour, garlic powder, onion powder, smoked paprika, salt, dry mustard, and black pepper.
- Step 5: Dip each onion into the buttermilk, shake off excess, then dredge in the flour mixture. Repeat this step for a double coating.
- Step 6: Carefully lower a few onions at a time into the hot oil, cut-side down. Fry for 3-4 minutes, then flip and fry for another 2 minutes until golden and crispy.
- Step 7: Remove onions with a slotted spoon and drain on paper towels. Season with additional salt and pepper if desired, then serve with buttermilk ranch dipping sauce.
Tips & Variations
- Use cipollini onions for their small size and sweetness, perfect for bite-sized servings.
- For extra crispiness, make sure the oil stays at 350˚F and avoid overcrowding the pot.
- Try swapping smoked paprika for cayenne pepper to add a spicy kick.
- If you don’t have buttermilk, mix 1 cup of milk with 1 tablespoon of lemon juice and let sit for 5 minutes.
Storage
Store leftover crispy mini bloomin’ onions in an airtight container in the refrigerator for up to 2 days. To reheat, place them on a baking sheet and warm in a preheated 375˚F oven for about 5-7 minutes to maintain their crispiness. Avoid microwaving, as this can make them soggy.

FAQs
Can I use a different type of onion?
Yes, you can use small onions like pearl onions or shallots, but cipollini onions are preferred for their size and sweetness.
Is it necessary to double coat the onions?
Double coating helps create a thicker, crunchier crust that holds up well during frying. It’s recommended for the best texture.
