Step‑by‑Step Instructions for Amazing Blooming Onion In Oven
Step 1: Preheat Your Oven
Begin by preheating your oven to 400°F (200°C). While it heats, prepare a baking sheet by lining it with parchment paper, ensuring an easy cleanup later. This step sets the stage for your amazing blooming onion in oven to achieve that perfect golden-brown crispiness during baking.
Step 2: Prepare the Onion
Peel the outer skin from your large yellow onion and slice off about half an inch from the top. Using a sharp knife, carefully make 12-16 vertical cuts downward, stopping just before you reach the root. Gently separate the onion petals in a blooming fashion, taking care not to break them apart.
Step 3: Create the Coating Mixture
In a shallow bowl, whisk together the all-purpose flour, paprika, garlic powder, cayenne pepper, salt, and black pepper until evenly combined. In another bowl, mix the milk and egg, creating a wet dip that will help your dry coating adhere beautifully to the onion. This mixture will ensure your amazing blooming onion in oven is both flavorful and crispy.
Step 4: Coat the Onion
Carefully dip the peeled and sliced onion into the milk mixture, allowing excess liquid to drip off. Next, dredge the onion in the flour mixture, making sure to coat all petals thoroughly for maximum crunchiness. The even coverage of the coating is essential for that perfect oven-baked texture.
Step 5: Bake to Perfection
Place the coated onion heartily on the prepared baking sheet, then drizzle olive oil over the top, ensuring it’s evenly distributed. Slide the sheet into the preheated oven and bake for 30-40 minutes, or until the onion is tender and golden brown, visually checking for the crisp and crunchy finish you desire from your amazing blooming onion in oven.
Step 6: Prepare the Dipping Sauce
While the blooming onion is baking, whip up a flavor-packed dipping sauce. In a bowl, combine mayonnaise, ketchup, horseradish, paprika, garlic powder, and cayenne pepper. Whisk until smooth and well blended, creating a delightful complement to your crispy onion appetizer that will be ready by the time your blooming onion finishes baking.
Step 7: Serve and Enjoy
Once your blooming onion is out of the oven, let it cool for a minute before serving hot. Carefully place it on a serving platter with your delicious dipping sauce alongside. Watch as family and friends gather around to pull apart the gourmet petals of this amazing blooming onion in oven, ready for guilt-free enjoyment!

Amazing Blooming Onion In Oven Recipe FAQs
How do I choose the best onion for this recipe?
Absolutely! A large yellow onion is ideal for achieving that classic blooming effect thanks to its flavor and structure. Look for firm onions with smooth, unblemished skins. Avoid any that show dark spots or soft areas, as these can indicate over-ripeness.

What if my blooming onion doesn’t open up properly?
Oh no, that can be a bummer! If your onion doesn’t bloom as expected, it might be due to not cutting deep enough or cutting through the root.
