Texas Roadhouse Cactus Blossom Ingredients
- Sweet Onions or Large Onion: Choose a large, sweet onion like Vidalia for the best flavor and size to create the iconic bloomed appearance.
- Eggs: Act as a binding agent in the batter.
- Buttermilk: Creates a batter that adheres well to the onion.
- All-Purpose Flour: Forms the base of the batter, providing a light coating that crisps up beautifully in the air fryer.
- Onion Powder: To enhance the onion flavor!
- Garlic Powder: Infuses the batter with a rich, savory taste.
- Paprika: Adds a sweet, smoky flavor to the batter.
- Kosher Salt and Black Pepper: Enhance the overall taste of the blooming onion.
- Cayenne Pepper: Brings gentle heat to the dish, adding complexity to the flavors.
How To Make Copycat Texas Roadhouse Cactus Blossom
Step 1: Preheat your air fryer to 350 degrees F (air fryer setting). Slice off about 1/2 inch from the stem end of the onion and peel the outer skin.
Step 2: Place the onion cut-side down, root end up, on a cutting board.
Starting about 1/2 inch from the root, make four evenly spaced cuts downwards to divide the onion into fourths (without cutting through the root). Between those cuts, make three more slices, again stopping before the root, to create “petals.” Turn the onion upright and gently separate the petals.
Step 3: In a medium bowl large enough to fit the onion, whisk together the eggs and buttermilk. Set aside.
Step 4: In another medium bowl, whisk together the flour, onion powder, garlic powder, paprika, salt, and cayenne pepper.
Step 5: Dip the onion into the buttermilk mixture, making sure to coat between the petals (you may need to use your hands). Then place the onion into the flour mixture, gently coating the entire surface and between the petals.
Repeat the dipping process once more: back into the buttermilk, then into the flour mixture for a thicker, crunchier coating. Shake off any excess flour as needed.
Step 6: Spray the air fryer basket with cooking spray. Place the onion cut-side up into the basket and spray the onion generously with cooking spray to help it crisp.
Set cook time for 20–25 minutes, or until the onion is golden brown and tender.
Open the air fryer every 8 minutes and reapply cooking spray to keep the onion crispy.
Copycat Texas Roadhouse Cactus Blossom Recipe Tips
- Use a large sweet onion like Vidalia for the best flavor and easier slicing.
- Make precise cuts and avoid cutting through the root so the onion stays intact.
- Separate the petals gently to allow the buttermilk and flour coating to reach every layer.
- Double-dip for extra crunch—dip the onion twice in buttermilk and flour mixtures.
- Generously spray cooking spray between petals and over the top for maximum crispiness.
- Don’t overcrowd the basket—make sure there’s room for hot air to circulate around the onion.
- Re-spray the onion during cooking every 8–10 minutes to keep it crispy and golden.
- Serve immediately for the best crunchy texture and freshest flavor.
Storing
- Storing: Store any leftover blooming onion in an airtight container in the refrigerator for up to 2–3 days. Keep it wrapped loosely in parchment paper to help maintain crispness.
- Freezing: Freezing is not recommended, as the texture of the crispy coating and tender onion may become soggy after thawing. It’s best to enjoy this blooming onion fresh for the best flavor and crunch.
- Reheating: Reheat in the air fryer at 350°F (175°C) for 4–6 minutes until hot and crispy again. Avoid microwaving, as it will make the coating soft and lose its crunch.
Cactus Blossom Recipe Faqs
What kind of onion should I use for a cactus blossom? Use a large sweet onion, like a Vidalia or Walla Walla, for the best flavor and texture. Their mild sweetness pairs perfectly with the savory batter and dipping sauce.
How do I cut the onion to get the “blossom” shape? Peel the onion and cut off the top (not the root). Place it root-side down and make vertical cuts all the way around, stopping about ½ inch from the bottom so it stays intact. Then gently spread out the petals.
What dipping sauce goes best with a cactus blossom? A zesty sauce made with mayo, ketchup, horseradish, and a few spices mimics the restaurant-style dip and adds a punch of flavor.
Can I make the onion ahead of time? It’s best served fresh for maximum crispiness, but you can prep the onion (cut and bread it) a few hours ahead. Store it in the fridge and fry right before serving.

Excited to make this over New Years! Didn’t see a dipping sauce recipe and never ordered an onion at a restaurant. Will try a mild horseradish aioli. Thanks for the great idea. P.S. I only have aerosol sprays. Don’t know ingredients for an oil spray that won’t clog a spray bottle. Wish me luck!
