Ingredients

• 1 large yellow onion
• 2 tablespoons olive oil
• 1/2 cup all-purpose flour
• 1 teaspoon paprika
• 1/2 teaspoon garlic powder
• 1/4 teaspoon cayenne pepper (optional)
• 1/2 teaspoon salt

• For the dipping sauce:
  • 1/2 cup mayonnaise
  • 2 tablespoons ketchup
  • 1 tablespoon prepared horseradish
  • 1/2 teaspoon paprika

Instructions

1. Step 1: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
2. Step 2: Peel the onion and cut off about 1/2 inch from the top. Do not cut the root end. Place the onion root-side up on the baking sheet.
3. Step 3: Make 12-16 evenly spaced cuts from the top down toward the root, stopping about 1/2 inch from the root to create petals.
4. Step 4: Gently separate and open the onion petals to loosen them.
5. Step 5: In a shallow bowl, whisk together the flour, paprika, garlic powder, cayenne pepper (if using), salt, and black pepper.
6. Step 6: In another shallow bowl, whisk the milk and egg together.
7. Step 7: Dip the onion into the milk and egg mixture, coating all the petals well. Let any excess drip off.
8. Step 8: Dredge the onion in the flour mixture, making sure all petals are coated. Shake off any excess flour gently.
9. Step 9: Place the coated onion on the prepared baking sheet and drizzle olive oil evenly over the petals.
10. Step 10: Bake for 30-40 minutes until the onion is tender and the petals are golden and slightly crispy.
11. Step 11: While baking, prepare the dipping sauce by whisking mayonnaise, ketchup, horseradish, paprika, garlic powder, and cayenne pepper in a small bowl.
12. Step 12: Serve the blooming onion warm with the dipping sauce on the side.

Tips & Variations

• Use a sharp knife for clean cuts to make separating the petals easier and safer.
• Adjust the cayenne pepper in the batter and sauce to suit your preferred spice level.
• For extra crispiness, place a wire rack over the baking sheet and bake the onion on the rack.
• Try swapping mayonnaise in the sauce for Greek yogurt for a lighter dip.

Storage

Store leftover baked blooming onion in an airtight container in the refrigerator for up to 2 days. Reheat gently in an oven or toaster oven at 350°F until warmed and crispy again. Avoid microwaving as it can make the onion soggy.

Instructions

1. Preheat the oven. Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper to prevent sticking and for easier cleanup.
2. Prepare the onion. Peel the onion and slice off about 1/2 inch from the top, being careful not to cut off the root end to hold the petals together. Place the onion root-side up on a cutting board.
3. Cut the onion petals. Make 12-16 evenly spaced cuts from the top down towards the root, stopping about 1/2 inch from the root end, creating petal-like sections without cutting through the bottom.
4. Separate the petals. Gently open the cut onion petals with your fingers to loosen them and create the blooming effect.
5. Mix the dry coating. In a shallow bowl, whisk together the all-purpose flour, paprika, garlic powder, cayenne pepper (if using), salt, and black pepper to create a seasoned flour blend.
6. Mix the wet coating. In another shallow bowl, whisk together the milk and egg until fully combined.
7. Coat the onion with wet mixture. Dip the blooming onion carefully into the milk and egg mixture, making sure all petals are evenly coated. Let any excess drip off.
8. Dredge the onion in dry mixture. Next, coat the onion thoroughly with the seasoned flour mixture, ensuring each petal is covered. Gently shake off the excess flour.
9. Prepare for baking. Place the coated onion on the lined baking sheet and drizzle olive oil evenly over the onion to help achieve a crispy exterior.
10. Bake the onion. Bake in the preheated oven for 30-40 minutes, or until the onion is tender inside and golden brown with slightly crispy petals.
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. Remove the blooming onion from the oven and serve immediately alongside the prepared dipping sauce for a flavorful and fun appetizer.

Notes

• For extra crispiness, you can flip the onion halfway through baking and drizzle additional olive oil on top.
• Adjust cayenne pepper amounts to control the heat level in both the coating and dipping sauce.
• If you prefer a dairy-free version, substitute milk with unsweetened almond or oat milk.
• The root end should stay intact to keep the petals together when baking and serving.
• Use a sharp knife for clean cuts when making the petals.
• This recipe is a healthier alternative to the traditional deep-fried blooming onion.
