Introduction
If you love the crunch and flavor of a classic bloomin’ onion but want something smaller and shareable, this recipe is for you. Crispy Mini Bloomin’ Onions with Creamy Buttermilk Ranch Dip make a perfect appetizer for parties, game day, or family gatherings. Bite-sized and packed with crispy petals and a rich dip, they’re sure to be a crowd-pleaser.

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)
- For the dip: 1 cup buttermilk, 1/2 cup mayonnaise, 1 teaspoon garlic powder, 1 teaspoon dried dill, salt and pepper to taste
Instructions
- Step 1: Peel the onions and cut off the top 1/4 inch. Place each onion cut-side down on a cutting board and slice downward, making 8-12 cuts all the way to the bottom but not through it, creating a flower effect.
- Step 2: Place the prepared onions in a large bowl and cover them with buttermilk. Let soak for 10-15 minutes to help the coating adhere.
- Step 3: In a separate bowl, mix the flour, seasoned breadcrumbs, paprika, garlic powder, cayenne pepper (if using), salt, and pepper.
- Step 4: Remove onions from buttermilk, letting excess drip off. Coat each onion thoroughly with the flour mixture, pressing gently to help it stick, then shake off any excess.
- Step 5: Heat vegetable oil in a deep skillet or fryer to 350°F (175°C), deep enough to submerge the onions. Test readiness by dropping a small amount of coating into the oil—it should sizzle and rise immediately.
- Step 6: Carefully lower one onion at a time into the hot oil using a slotted spoon. Fry for 3-4 minutes until golden brown and crispy. Drain on paper towels and repeat, maintaining oil temperature.
- Step 7: While frying, prepare the dip by mixing 1 cup buttermilk, 1/2 cup mayonnaise, 1 teaspoon garlic powder, 1 teaspoon dried dill, and salt and pepper to taste. Stir well and adjust seasoning.
- Step 8: Serve the crispy mini bloomin’ onions on a platter with the creamy buttermilk ranch dip. Garnish with chopped parsley or chives if desired and enjoy!
Tips & Variations
- If you lack buttermilk, substitute by mixing regular milk with 1 tablespoon vinegar or lemon juice.
- For a gluten-free version, use gluten-free flour and breadcrumbs.
- To bake instead of fry, place coated onions on a baking sheet and bake at 425°F (220°C) for 20-25 minutes, turning halfway.
- Substitute sour cream for mayonnaise in the dip for a lighter option.
- Use whole wheat flour and breadcrumbs for added fiber and nutrients.
Storage
Store leftover bloomin’ onions in an airtight container in the refrigerator for up to 2 days. Reheat in an oven to restore their crispiness. For convenience, prepare onions up to the coating stage in advance and refrigerate until ready to fry.

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
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, then slice downward into the onion 8-12 times without cutting through the bottom, creating a flower or blooming shape.
- Soak in Buttermilk: Place the prepared onions in a large bowl and cover them with 1 cup of buttermilk. Let soak for at least 10-15 minutes to help the coating adhere during frying.
- Prepare the Coating: In a separate bowl, combine 1 cup flour, 1 cup seasoned breadcrumbs, paprika, garlic powder, cayenne pepper (if using), salt, and pepper. Mix thoroughly to create the dry coating mixture.
- Coat the Onions: Remove onions from buttermilk, allowing excess to drip. Carefully coat each onion thoroughly in the flour mixture, ensuring to get in between the petals. Press gently to help the coating adhere, then shake off any excess.
- Heat the Oil: Pour vegetable oil into a deep skillet or deep fryer to a depth of about 2-3 inches. Heat the oil to 350°F (175°C). Test readiness by dropping a small amount of coating; it should sizzle and rise immediately.
- Fry the Onions: Gently lower one onion at a time into the hot oil using a slotted spoon. Fry for 3-4 minutes or until golden brown and crispy. Remove and drain on paper towels. Repeat with remaining onions, maintaining oil temperature.
- Make the Creamy Buttermilk Ranch Dip: While onions fry, combine 1 cup buttermilk, 1/2 cup mayonnaise, 1 teaspoon garlic powder, 1 teaspoon dried dill, salt, and pepper in a bowl. Stir well and adjust seasoning if needed.
