How to Make Bloomin’ Onion Petals
Prepare the Sauce: In a bowl, whisk together the mayonnaise, sour cream, ketchup, horseradish, garlic, kosher salt, black pepper, smoked paprika, and cayenne until smooth. Cover with plastic wrap and refrigerate until serving.
Slice the Onion: Cut the root end off the large sweet onion and peel. Slice the onion in half, then quarter it. Cut the quarters in half to create your petals and set aside.
Mix the Flour Mixture: In a large bowl, combine the all-purpose flour, seasoned salt, pepper, garlic powder, cayenne pepper, onion powder, and smoked paprika. Stir until everything is well mixed and evenly distributed.
Whisk Wet Ingredients: In a separate medium bowl, pour in the buttermilk and crack in the large egg. Whisk them together until fully combined and slightly frothy.
Coat the Onion Petals: Place the onion petals in a gallon-sized ziptop bag and add ¼ cup of the flour mixture. Seal the bag and shake to coat the onions as best as you can with flour.
Dunk in Buttermilk: Take a handful of the floured onion petals at a time. Gently shake off any excess flour and dip them into the buttermilk mixture, allowing any liquid to drip off.
Recoat with Flour: Add the dipped onion petals back to the bowl with the leftover flour mixture. Coat them well and shake off any excess flour again.
Set on Tray: Place the coated onion petals onto a parchment-lined sheet tray while continuing to coat the remaining petals. This keeps them from sticking together.
Heat the Oil: In your deep fryer or a deep-sided skillet, heat about 2 inches of oil to 350°F. You can test by dropping a small bit of flour in; it should sizzle immediately.
Fry the Petals: Carefully add the onion petals to the hot oil and fry for about 3-4 minutes, or until they turn golden brown. Work in batches to avoid overcrowding the pan.
Drain and Serve: Once fried, transfer the onion petals to a plate lined with paper towels to soak up excess oil. Place them on a wire rack to keep them crisp while frying the rest. Finally, serve with your prepared dipping sauce and enjoy!
Optional: Garnish with fresh herbs for a pop of color and flavor.

Tips for the Best Bloomin’ Onion Petals
- Fresh Ingredients: Use the freshest sweet onion you can find for maximum flavor. An older onion may be overly pungent and affect the overall taste.
- Double-Dip Method: For extra crispy petals, consider double-dipping in the buttermilk mixture before coating in flour again. This adds a thicker, crunchier coating!
- Temperature Check: Ensure your frying oil reaches 350°F before adding the petals to achieve an even golden color. Too low, and they’ll absorb excess oil, becoming soggy.
- Batch Frying: Fry in small batches to prevent overcrowding, which can lower oil temperature and hinder proper frying. Think of each batch as a beautiful moment of golden magic!
- Cooling Technique: Place fried petals on a wire rack over a sheet tray to cool, allowing excess oil to drip off while keeping them crispy no one wants soggy snacks!
- Adjust Your Spice: Feel free to tweak the cayenne pepper in the sauce for the dipping sauce to match your palate. A little heat can go a long way in enhancing the Bloomin’ Onion Petals!

How to Store and Freeze Bloomin’ Onion Petals
Room Temperature: Let your Bloomin’ Onion Petals cool completely before storing them at room temperature for up to 2 hours; tightly cover to prevent them from drying out.
Fridge: Store any leftover petals in an airtight container in the fridge for up to 3 days. Reheat in the oven at 350°F for about 10 minutes to restore crispiness.
Freezer: If you want to save leftovers, freeze the uncooked coated onion petals on a baking tray until solid, then transfer to a ziptop bag for up to 2 months. Fry directly from frozen when ready!
Reheating: For the best results, reheat in an air fryer or conventional oven to ensure you regain that crispy texture instead of using a microwave.
Make Ahead Options

When you’re ready to fry, dip the chilled petals into the buttermilk mixture and re-coat them with flour, then fry as directed.

Bloomin’ Onion Petals Recipe FAQs
How do I choose the right onion for Bloomin’ Onion Petals?
Absolutely! For this recipe, I recommend using a large sweet onion, such as Vidalia or Walla Walla, as their mild flavor perfectly complements the dish. Look for onions that are firm with shiny, unblemished skin avoid ones with dark spots or soft spots, as they may be overripe.
What s the best way to store leftover Bloomin’ Onion Petals?
Leftover Bloomin’ Onion Petals can be stored in an airtight container in the fridge for up to 3 days. Just ensure they are fully cooled before sealing. To reheat, pop them in the oven at 350°F for about 10 minutes to regain that lovely crunch!
Can I freeze the coated onion petals for later use?
Very much so! To freeze your coated onion petals, spread them in a single layer on a baking sheet and place them in the freezer until fully frozen. Once frozen, transfer them to a ziptop bag, pressing out as much air as possible. These can be kept for up to 2 months! When you’re ready to fry, there’s no need to thaw; just add them straight to the hot oil for a quick and crispy treat.
What if my onion petals don t bloom as expected?
If your onion petals aren’t blooming properly while frying, the oil might be too hot or too cold. Make sure the oil temperature is around 350°F this provides the perfect environment for crispy, fully opened petals. Also, ensure you’re not overcrowding the pan, as this can cause steam to build up, preventing them from crisping.
Are there any dietary considerations I should keep in mind?
Definitely! If anyone in your gathering has allergies, be mindful of the ingredients, especially the egg, dairy (buttermilk, mayonnaise, and sour cream), and gluten in the flour. For a gluten-free option, you can substitute the all-purpose flour with a gluten-free flour blend. And always double-check for any personal dietary restrictions to ensure everyone can enjoy these festive Bloomin’ Onion Petals!
