Grilled Onion Blossoms with Parmesan and Spicy Dipping Sauce Recipe

Introduction

Grilled Onion Blossoms are a fun and flavorful appetizer that transforms sweet Vidalia onions into a crispy, blooming treat. Served with a creamy, tangy dipping sauce, they’re perfect for sharing at any gathering or enjoying as a tasty snack.

Ingredients

• 1/4 cup mayonnaise
• 1/4 cup sour cream
• 1 tablespoon ketchup
• 1 teaspoon Worcestershire sauce
• 1/2 teaspoon paprika
• Pinch of cayenne pepper
• 1/2 cup finely grated Parmesan cheese
• 1 tablespoon paprika
• 1/8 teaspoon cayenne pepper
• 1/2 teaspoon Italian seasoning
• 4 sweet Vidalia onions, peeled with root end intact
• Fresh chopped parsley, for serving
• Oil for drizzling
• Salt, to taste

Instructions

1. Step 1: Preheat your grill to medium-high heat. In a small bowl, combine mayonnaise, sour cream, ketchup, Worcestershire sauce, 1/2 teaspoon paprika, and a pinch of cayenne pepper. Season with salt and mix well to create the dipping sauce.
2. Step 2: In another small bowl, mix together the Parmesan cheese, 1 tablespoon paprika, 1/8 teaspoon cayenne, and Italian seasoning. Season this spice mixture with salt.
3. Step 3: Cut the stem off each onion and place it flat side down. Carefully cut from the root end about 1/2 inch down into 12 to 16 sections, being careful not to cut all the way through the root so the onion stays intact. Flip the onion over and gently pull the sections apart to separate the petals.
4. Step 4: Sprinkle the cheese-spice mixture evenly over the separated onion petals. Drizzle the onions lightly with oil to prevent sticking and enhance grilling.
5. Step 5: Place the onions on the grill, cover, and cook for about 15 minutes, until the onions are tender and have a light char.
6. Step 6: Remove the onions from the grill, garnish with fresh chopped parsley, and serve warm with the prepared dipping sauce.

Tips & Variations

• For a smoky flavor, add a few wood chips to your grill before cooking the onions.
• Substitute Greek yogurt for sour cream in the dipping sauce for a lighter version.
• Try adding a sprinkle of smoked paprika or chili powder to the cheese-spice mix for extra heat.
• If you don’t have a grill, you can bake the onions in a preheated 400°F oven for 20–25 minutes.

Storage

Store leftover grilled onion blossoms in an airtight container in the refrigerator for up to 2 days. Reheat gently in the oven or air fryer to maintain crispness. Keep the dipping sauce separate in a sealed container and stir before serving.

FAQs

Can I use other types of onions for this recipe?

Sweet Vidalia onions are ideal due to their mild flavor and size, but you can use other large sweet onions like Walla Walla or Maui onions for similar results.

How do I ensure the onion petals separate without breaking?

Make sure to cut deeply enough without slicing through the root end. After cutting, gently pull the petals apart slowly to avoid breaking. The root acts as a natural hinge to keep the onion intact while opening.
