6. Step 6: In another shallow bowl, whisk together the milk and egg until combined.
7. Step 7: Dip the onion into the milk and egg mixture, making sure all petals are coated. Let excess drip off.

9. Step 9: Place the coated onion on the prepared baking sheet and drizzle olive oil over it.
10. Step 10: Bake for 30 to 40 minutes until the onion is tender and golden brown, with slightly crispy petals.
11. Step 11: While the onion bakes, whisk together mayonnaise, ketchup, horseradish, paprika, garlic powder, and cayenne pepper in a small bowl to make the dipping sauce.
12. Step 12: Serve the blooming onion hot with the dipping sauce immediately.

Tips & Variations

• For extra crispiness, place the onion on a wire rack set over the baking sheet to allow air circulation.
• Try adding smoked paprika or chili powder to the flour mixture for a smoky or spicier flavor.
• If you prefer a dairy-free version, substitute milk with unsweetened almond or oat milk.
• The dipping sauce can be customized with a splash of hot sauce or minced fresh herbs like chives.

Storage

Store any leftover blooming onion in an airtight container in the refrigerator for up to 2 days. Reheat gently in the oven at 350°F (175°C) for about 10 minutes to restore the crispiness. The dipping sauce can be kept separately in the fridge for up to 3 days.

---

Instructions

1. Preheat the Oven: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper to ensure easy cleanup and prevent sticking.
2. Prepare the Onion: Peel the onion and slice off about 1/2 inch from the top, but keep the root end intact. Place the onion root side up on your cutting surface for stability.
3. Cut the Onion into Petals: Make 12 to 16 evenly spaced cuts from the top of the onion down towards the root, stopping about 1/2 inch from the root to keep the onion intact. This creates the signature blooming petals.
4. Separate the Petals: Gently pull apart the onion petals to loosen them, forming the blooming shape but being careful not to break the petals.
5. Prepare the Flour Mixture: In a shallow bowl, whisk together flour, paprika, garlic powder, cayenne pepper if using, salt, and black pepper until well combined.
6. Prepare the Wet Mixture: In another shallow bowl, whisk together the milk and egg until fully mixed.
7. Dip the Onion in Wet Mixture: Carefully dip the entire onion into the milk and egg mixture, making sure to coat all the petals thoroughly. Allow any excess to drip off.
8. Dredge in Flour Mixture: Next, coat the onion thoroughly in the seasoned flour mixture, ensuring each petal is covered. Gently shake off any excess flour to avoid clumping.
9. Place and Drizzle: Set the coated onion upright on the baking sheet. Drizzle the olive oil evenly over the onion to help it crisp up and bake evenly.
10. Bake the Onion: Bake in the preheated oven for 30 to 40 minutes, or until the onion petals are tender and golden brown with slightly crispy edges.
11. Prepare the Dipping Sauce: While the onion bakes, whisk together mayonnaise, ketchup, prepared horseradish, paprika, garlic powder, and a pinch of cayenne pepper in a small bowl until smooth and well combined.
12. Serve: Serve the blooming onion immediately while warm, paired with the prepared dipping sauce for a delicious, savory treat.

Notes

• Do not cut through the root end to keep the onion intact when blooming.
• Use a sharp knife for cleaner, safer cuts of the onion petals.
• For extra crispiness, you can broil the onion for the last 2-3 minutes of baking but watch closely to avoid burning.
• If you want a spicier dip, increase the amount of horseradish or cayenne pepper.
• This recipe can be made gluten-free by substituting the all-purpose flour with a gluten-free flour blend.
• Leftovers are best eaten the same day as the onion may lose its crispiness over time.
