Each ingredient plays a key role, from the sweet onion providing that signature crunch and sweetness to the perfectly seasoned flour blend that gives you that salty, spicy kick with every bite.
- 1 large sweet onion (such as Vidalia): Choose a large, firm onion with minimal bruising for ideal petal separation and sweetness.

How to Make Outback Steakhouse Bloomin’ Onion Recipe
Step 1: Prepare the Onion
Start by trimming about half an inch off the top of your large sweet onion and peeling it, carefully keeping the root end intact — this is essential to hold those petals together. Next, make 12 to 16 cuts around the onion to create the petals, slicing down almost to the root but not through it. After flipping it over, gently separate each petal with your fingers to help it “bloom” like a beautiful flower.
Step 2: Mix the Flour and Seasonings
Combine your 3 cups of all-purpose flour with the paprika, garlic powder, onion powder, cayenne pepper, black pepper, oregano, and salt in a large bowl. This perfectly seasoned flour mix is what gives your bloomin’ onion that iconic flavor and crispy texture.
Step 3: Prepare the Egg Wash
In a separate bowl, whisk together the two eggs and one cup of milk until smooth. This egg wash will make sure the flour sticks to every petal for that irresistible crunch.
Step 4: Dredge and Coat the Onion
Dunk your onion into the seasoned flour, making sure to coat every petal thoroughly. Then, dip it into the egg wash. After that, return it to the flour mixture for a second coating to create that thick, crunchy shell we all love. Press a little flour onto each petal to ensure it’s really covered.
Step 5: Chill the Onion
Pop the coated onion into the fridge for about 30 minutes. This step helps the batter set and keeps everything intact during the frying process, which is key for achieving a perfect crispy crust.
Step 6: Fry the Onion
Heat your oil to 375 degrees Fahrenheit (190 degrees Celsius) in a deep fryer or a deep, heavy pot. Gently place the onion root-side up into the hot oil and fry for 6 to 8 minutes, or until it reaches a gorgeous golden-brown color. Once done, drain it on paper towels to remove excess oil.
Step 7: Make the Signature Dipping Sauce
While the onion cools just enough to handle, whisk together mayonnaise, ketchup, prepared horseradish, paprika, salt, garlic powder, dried oregano, black pepper, and a dash of cayenne pepper if you like it spicy. Chill this in the fridge until you’re ready to serve.
Step 8: Serve Hot with Sauce
Place your golden fried bloomin’ onion on a platter with the dipping sauce either in the center or on the side for that perfect combination of crispy, tender, and creamy with every bite. Get ready for compliments!
How to Serve Outback Steakhouse Bloomin’ Onion Recipe
Garnishes
A sprinkle of fresh parsley or chives over the bloomin’ onion not only adds a lovely pop of color but also introduces a fresh, herbal contrast that brightens up the earthy flavors. You can also serve with lemon wedges for a hint of acidity if you want to mix things up.
Side Dishes
The Outback Steakhouse Bloomin’ Onion Recipe is a showstopper all on its own, but pairing it with some classic sides like creamy mashed potatoes, crisp garden salad, or even tangy coleslaw creates a well-rounded, satisfying meal. If you’re serving this appetizer-style, consider offering some cold beer or a zesty iced tea to balance the richness.
Creative Ways to Present
Want to wow your guests even more? Arrange the bloomin’ onion on a rustic wooden board surrounded by small bowls of additional dipping sauces such as ranch, chipotle mayo, or even BBQ sauce. For a party twist, serve mini versions of the bloomin’ onion on individual skewers for easy snacking while mingling.
Make Ahead and Storage
Storing Leftovers
If you have any leftover bloomin’ onion (though it’s rare!), store it in an airtight container in the fridge for up to 2 days. Keep the dipping sauce separate to prevent the onion from getting soggy and compromising that beautiful crunch.
Freezing
While not ideal because the texture suffers, you can freeze the cooked onion petals in a single layer on a baking sheet, then transfer them to a freezer bag for up to 1 month. For best results, reheat directly from frozen in a hot oven to try to regain some crispness.
Reheating
Reheat leftovers in a 350°F oven on a wire rack rather than the microwave to help keep the onion crispy. It may not be quite as perfect as fresh, but this method maintains the texture and warms it evenly without turning it soggy.
FAQs
Can I use a regular onion instead of a sweet onion for the Outback Steakhouse Bloomin’ Onion Recipe?
Absolutely! Sweet onions like Vidalias have the best natural sweetness and a milder flavor, but if you don’t have one on hand, a large yellow onion will work just fine. Just expect a slightly stronger onion flavor.
Is deep frying necessary, or can I bake the bloomin’ onion?
Deep frying is the traditional method and yields that classic crispy texture everyone loves. Baking can be a healthier alternative, but it won’t get as crunchy or golden brown. If you try baking, coat the onion well and bake at a high temperature, but be prepared for a different texture.
How spicy is the dipping sauce in the Outback Steakhouse Bloomin’ Onion Recipe?
The dipping sauce has a mild to moderate spiciness balanced by creamy mayo and tangy ketchup. You can adjust the heat by adding more or less horseradish and cayenne pepper depending on your preference.
Can I prepare the dipping sauce ahead of time?
Yes! In fact, making the dipping sauce a few hours or even a day ahead allows the flavors to meld beautifully. Just keep it refrigerated and give it a quick stir before serving.
What oil is best for frying the bloomin’ onion?
Vegetable or canola oil are great choices due to their high smoke points and neutral flavor, which won’t overpower the delicate seasoning on the onion. Avoid olive oil as it has a lower smoke point and might burn.

Ingredients
Onion and Breading
- 1 large sweet onion (such as Vidalia)
- 3 cups all-purpose flour
- 2 tsp paprika
- 1 tsp garlic powder
- 1 tsp onion powder
- 1/2 tsp cayenne pepper
- 1/2 tsp black pepper
- 1/2 tsp dried oregano
- 1/2 tsp salt
- 2 large eggs
- 1 cup milk
- Vegetable or canola oil (enough for deep frying)
Dipping Sauce
- 1/2 cup mayonnaise
- 2 tbsp ketchup
- 2 tbsp prepared horseradish
- 1/2 tsp paprika
- 1/2 tsp salt
- 1/4 tsp garlic powder
- 1/4 tsp dried oregano
- Pinch of black pepper
- Dash of cayenne pepper (optional)
Instructions
- Prepare the Onion: Cut off 1/2 inch from the top of the onion and peel it, keeping the root end intact. Make 12 to 16 vertical cuts around the onion to create petal-like sections, stopping just before the root to keep the onion intact. Turn the onion over and carefully separate the layers to resemble a blooming flower.
- Mix Dry Seasonings: In a large bowl, combine the all-purpose flour, paprika, garlic powder, onion powder, cayenne pepper, black pepper, dried oregano, and salt. Stir well to ensure even distribution of spices.
- Whisk Egg Mixture: In a separate bowl, whisk together the eggs and milk until smooth and combined. This will serve as the wet coating for the onion.
- Coat the Onion: Carefully dredge the prepared onion in the seasoned flour mixture, making sure to coat all the petals thoroughly. Then dip the onion in the egg and milk mixture, allowing excess to drip off. Finally, return the onion to the flour mixture for a second coating, pressing flour gently onto the petals to ensure a thick, even breading.
- Chill to Set Coating: Place the coated onion in the refrigerator for 30 minutes. This step helps firm up the breading so it adheres well during frying and maintains its shape.
- Heat Oil: Preheat vegetable or canola oil in a deep fryer or large pot to 375°F (190°C). The oil should be deep enough for the onion to be fully submerged while frying.
- Fry the Onion: Carefully place the onion root side up into the hot oil. Fry for 6 to 8 minutes until the onion is golden brown and crispy. Use tongs or a slotted spoon to remove it and drain excess oil on paper towels.
- Prepare the Dipping Sauce: In a small bowl, combine mayonnaise, ketchup, prepared horseradish, paprika, salt, garlic powder, dried oregano, black pepper, and a dash of cayenne pepper (if using). Mix until smooth and chill the sauce before serving to meld flavors.
- Serve: Serve the Bloomin’ Onion hot, with the chilled dipping sauce either on the side or in the center for dipping. Enjoy this classic appetizer fresh for the best flavor and texture.
Notes
- Use a large sweet onion like Vidalia for the best flavor and shape.
- Ensure oil temperature is steady at 375°F to achieve a crispy crust without absorbing too much oil.
- Press flour into the petals thoroughly to create a thick, crunchy coating.
- Chilling the coated onion before frying helps prevent breading from falling off.
- The dipping sauce can be made ahead and refrigerated to allow flavors to blend.
- Use a deep pot or fryer to safely deep-fry the onion without overcrowding.
- Be cautious when lowering and removing the onion from hot oil to avoid splashes.
