Ingredients

Scale

Onions and Coating

  • 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, enough for 2-3 inches deep)

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

  • Buttermilk substitute: regular milk mixed with 1 tablespoon vinegar or lemon juice
  • Gluten-free option: use gluten-free flour and gluten-free breadcrumbs
  • For a lighter dip: substitute sour cream for mayonnaise

Instructions

  1. Prepare the Onions: Peel the onions and cut off the top 1/4 inch to create a flat surface. Place each onion cut-side down on a cutting board and carefully make 8-12 vertical cuts around the onion, slicing down to the bottom but not all the way through, forming individual petals resembling a flower.
  2. Soak in Buttermilk: Place the cut onions in a large bowl and cover with buttermilk. Allow them to soak for at least 10-15 minutes. This helps the coating stick and tenderizes the onions.
  3. Prepare the Coating: In a separate bowl, thoroughly mix the all-purpose flour, seasoned breadcrumbs, paprika, garlic powder, cayenne pepper (if using), salt, and pepper to create the dredging mixture.
  4. Coat the Onions: Remove each onion from the buttermilk, letting excess drip off. Carefully dredge each onion in the flour mixture, making sure to get the coating between all petals. Press the mixture gently to help it adhere, then shake off extra coating.
  5. Heat the Oil: In a deep skillet or fryer, pour vegetable oil about 2-3 inches deep and heat to 350°F (175°C). Test readiness by dropping a bit of the coating into the oil; it should sizzle and float to the surface immediately.
  6. Fry the Onions: Using a slotted spoon, carefully lower one onion at a time into the hot oil. Fry each for 3-4 minutes until golden brown and crispy. Remove and drain on paper towels to remove excess oil. Fry onions in batches to maintain oil temperature and crispiness.
  7. Make the Creamy Buttermilk Ranch Dip: While frying, mix 1 cup buttermilk, 1/2 cup mayonnaise, 1 teaspoon garlic powder, 1 teaspoon dried dill, and salt and pepper to taste in a bowl. Stir until smooth and adjust seasoning as needed.
  8. Serve and Enjoy: Arrange the crispy mini bloomin’ onions on a serving platter alongside the ranch dip. Garnish with chopped parsley or chives if desired and serve immediately.

Notes

  • Soaking onions long enough in buttermilk ensures the coating sticks better and yields a crispier texture.
  • Do not overcrowd the frying pan; fry a few onions at a time to keep oil temperature consistent and prevent sogginess.
  • Drain fried onions on paper towels to remove excess oil and maintain crispness.
  • Store leftovers in an airtight container in the refrigerator for up to 2 days; reheat in the oven to restore crispiness.
  • For a healthier alternative, bake coated onions at 425°F (220°C) for 20-25 minutes, turning halfway through.
  • Use gluten-free flour and breadcrumbs for a gluten-free recipe variation.
  • Substitute sour cream for mayonnaise in the dip for a lighter option.
