Ingredients
- 4 small to medium-sized onions (Vidalia or sweet onions work best)
- 1 cup buttermilk
- 1 cup all-purpose flour
- 1 cup seasoned breadcrumbs
- 1 teaspoon paprika
- 1 teaspoon garlic powder
- 1/2 teaspoon cayenne pepper (optional, for extra heat)
- Salt and pepper to taste
- Vegetable oil (for frying)
- 1/2 cup mayonnaise (for the dip)
- 1 teaspoon dried dill (for the dip)
Instructions
- Step 1: Peel the onions and cut off the top 1/4 inch. Place each onion cut-side down and slice 8-12 times from top to bottom, stopping just before the root to create a flower shape.
- Step 2: Submerge the onions in a bowl of buttermilk and soak for 10-15 minutes to help the coating stick.
- Step 3: In a separate bowl, mix flour, seasoned breadcrumbs, paprika, garlic powder, cayenne pepper (if using), salt, and pepper to create the coating mixture.
- Step 4: Remove onions from buttermilk, letting the excess drip off. Coat each onion thoroughly in the flour mixture, pressing gently between the petals. Shake off any extra coating.
- Step 5: Heat vegetable oil in a deep skillet or fryer to 350°F (175°C), ensuring it’s deep enough to submerge the onions.
- Step 6: Fry each onion carefully in the hot oil for 3-4 minutes or until golden and crispy. Drain on paper towels. Maintain oil temperature and fry in batches.
- Step 7: For the dip, combine 1 cup buttermilk, 1/2 cup mayonnaise, garlic powder, dried dill, salt, and pepper in a bowl. Stir until smooth and adjust seasoning as needed.
- Step 8: Serve the crispy bloomin’ onions with the creamy ranch dip. Garnish with chopped parsley or chives if desired.
Tips & Variations
- Substitute regular milk mixed with 1 tablespoon vinegar or lemon juice for buttermilk if unavailable.
- For a gluten-free version, use gluten-free flour and breadcrumbs.
- Bake coated onions at 425°F (220°C) for 20-25 minutes, flipping halfway, for a healthier alternative.
- Replace mayonnaise with sour cream in the dip for a lighter option.
- Use whole wheat flour and breadcrumbs for added fiber and nutrients.
- Don’t overcrowd the fryer to keep the oil temperature steady and onions crispy.
Storage
Store leftover mini bloomin’ onions in an airtight container in the refrigerator for up to 2 days. Reheat in an oven to restore crispiness rather than using a microwave. You can prepare the onions up to coating ahead of time and refrigerate before frying for convenience.

FAQs
Can I make these mini bloomin’ onions ahead of time?
You can prepare the onions in advance up to the frying step and keep them refrigerated. Fry them just before serving for the best crisp texture.

Sweeter onions like Vidalia or Walla Walla are ideal due to their mild flavor and tenderness, though regular yellow onions can also be used if needed.

Yes, baking is a healthier choice. Coat the onions and bake at 425°F (220°C) for 20-25 minutes, turning halfway through until crispy.

Ingredients
For the Mini Bloomin’ Onions
- 4 small to medium-sized onions (Vidalia or sweet onions work best)
- 1 cup buttermilk
- 1 cup all-purpose flour
- 1 cup seasoned breadcrumbs
- 1 teaspoon paprika
- 1 teaspoon garlic powder
- 1/2 teaspoon cayenne pepper (optional, for extra heat)
- Salt and pepper to taste
- Vegetable oil (for frying, about 2-3 inches deep)
For the Creamy Buttermilk Ranch Dip
- 1 cup buttermilk
- 1/2 cup mayonnaise
- 1 teaspoon garlic powder
- 1 teaspoon dried dill
- Salt and pepper to taste
Substitutions
- Substitute sour cream for mayonnaise in the ranch dip for a lighter option
- Use gluten-free flour and breadcrumbs for a gluten-free version
- Make buttermilk substitute by mixing regular milk with 1 tablespoon vinegar or lemon juice
- Use whole wheat flour and breadcrumbs for added fiber and nutrients
Instructions
- Prepare the Onions: Peel the onions and cut off the top 1/4 inch. Place each onion cut-side down on a cutting board and make 8-12 downward cuts all the way to the base without slicing through, to create a blooming flower effect.
- Soak in Buttermilk: Place the prepared onions in a large bowl and cover them with buttermilk. Let soak for at least 10-15 minutes to help the coating adhere better during frying.
- Prepare the Coating: In a separate bowl, combine flour, seasoned breadcrumbs, paprika, garlic powder, cayenne pepper (if using), salt, and pepper. Mix thoroughly to create a flavorful coating mixture.
- Coat the Onions: Remove onions from buttermilk and allow excess to drip off. Carefully coat each onion in the flour mixture, ensuring the coating gets in between the petals. Press gently to help it stick and shake off any excess.
- Heat the Oil: Pour vegetable oil into a deep skillet or fryer to a depth of about 2-3 inches. Heat oil to 350°F (175°C). Test readiness by dropping a small amount of coating into the oil; it should sizzle and rise immediately.
- Fry the Onions: Using a slotted spoon, gently lower one onion at a time into the hot oil. Fry for 3-4 minutes until golden brown and crispy. Remove and drain on paper towels to remove excess oil. Maintain oil temperature and repeat with remaining onions.
- Make the Creamy Buttermilk Ranch Dip: While onions fry, combine buttermilk, mayonnaise, garlic powder, dried dill, salt, and pepper in a bowl. Stir until well mixed and adjust seasoning as desired.
- Serve and Enjoy: Arrange the crispy mini bloomin’ onions on a serving platter, accompany with the creamy ranch dip, and garnish with freshly chopped parsley or chives if desired. Serve immediately for best texture and flavor.
Notes
- Soaking onions in buttermilk is crucial for coating adhesion and flavor.
- Fry only a couple of onions at a time to avoid dropping oil temperature and soggy results.
- Drain fried onions on paper towels to maintain crispiness.
- Store leftovers in an airtight container in the refrigerator for up to 2 days; reheat in an oven to restore crispness.
- For a healthier alternative, bake coated onions at 425°F (220°C) for 20-25 minutes, flipping halfway through.
- Use sweeter onions like Vidalia or Walla Walla for best taste and tenderness.
- Make sure not to cut through the bottom of the onion when slicing, so the petals remain attached.
