I love this bloomin onion dipping sauce because it adds a perfect creamy and tangy kick to crispy fried onions. It’s simple to make and always a hit when I serve it to friends or family. Scroll down to see how easy it is to whip up this tasty sauce at home.
Most of the ingredients in this sauce are common pantry staples like mayonnaise, ketchup, and spices. The one you might not have on hand is prepared horseradish, which you can find in the condiment aisle of the supermarket. It adds a nice spicy zing, so don’t skip it if you want that classic flavor.

Ingredients For Bloomin Onion Dipping Sauce Recipe
Mayonnaise: This creamy base gives the sauce its smooth texture and rich flavor.
Ketchup: Adds a touch of sweetness and tang to balance the sauce.
Prepared horseradish: A spicy root condiment that brings a sharp, zesty kick.
Paprika: A mild spice that adds color and a subtle smoky taste.
Salt: Enhances all the flavors in the sauce.
Garlic powder: Gives a gentle garlic flavor without the texture of fresh garlic.
Dried oregano: Adds a hint of herbal earthiness.
Black pepper: Provides a little heat and depth to the sauce.
Technique Tip for This Dipping Sauce
When you’re mixing the ingredients for this Bloomin Onion Dipping Sauce, one simple trick can make everything come together perfectly: whisking without splashing. Here’s how to do it step by step:
- Use a bowl that’s big enough so the sauce won’t spill over the sides when you stir.
- Hold your whisk firmly but gently, and start stirring slowly in a circular motion.
- Gradually increase your speed as the ingredients start to blend, but don’t rush it.
- Keep the whisk mostly under the surface of the sauce to avoid splashing.
- If you notice any sauce on the sides of the bowl, pause and scrape it down with a spoon or spatula before continuing.
Whisking this way helps the mayonnaise, ketchup, and spices mix smoothly into a creamy, even sauce. If you whisk too fast or splash, you might end up with a mess on your counter or uneven seasoning in the sauce. Taking your time means the flavors blend better, and the texture feels just right when you dip your bloomin onion.
I remember the first time I made a sauce like this, I got a little too excited and whisked way too fast. The sauce splattered everywhere, and I had to clean up before I could finish. Now, I always start slow and keep the whisk low in the bowl. It saves time and keeps the kitchen clean. Also, letting the sauce chill in the fridge for at least 30 minutes after mixing helps the flavors settle and taste even richer. It’s like giving the sauce a little nap before it’s ready to party with your crispy onion!

Alternative Ingredients
mayonnaise - Substitute with Greek yogurt: Greek yogurt provides a similar creamy texture with a tangy flavor and is a healthier alternative.
ketchup - Substitute with tomato paste: Tomato paste can be mixed with a bit of vinegar and sugar to mimic the sweetness and tanginess of ketchup.
prepared horseradish - Substitute with wasabi: Wasabi offers a similar spicy kick, though it is more intense, so use sparingly.
paprika - Substitute with cayenne pepper: Cayenne pepper adds heat and a similar color, but use less as it is spicier.
salt - Substitute with soy sauce: Soy sauce adds saltiness along with a depth of umami flavor.
garlic powder - Substitute with fresh garlic: Fresh garlic provides a more robust flavor; use minced garlic in a slightly smaller amount.

How to Store or Freeze This Dipping Sauce
- Ensure the dipping sauce is stored in an airtight container to maintain its freshness and prevent any unwanted flavors from seeping in.
- Place the container in the refrigerator. The Bloomin Onion Dipping Sauce can be stored for up to one week, ensuring you have a delicious accompaniment ready for your appetizers.
- If you wish to freeze the sauce, transfer it to a freezer-safe container. Leave a small gap at the top to allow for expansion as it freezes.
- Label the container with the date to keep track of its freshness. The dipping sauce can be frozen for up to three months.
- When ready to use, thaw the sauce in the refrigerator overnight. Give it a good stir to restore its creamy consistency before serving.
- Avoid refreezing the sauce once it has been thawed, as this can affect the texture and flavor.
- For best results, always use clean utensils when scooping out the sauce to prevent contamination and extend its shelf life.
How to Reheat Leftovers
Place the Bloomin Onion Dipping Sauce in a microwave-safe bowl. Heat on medium power for 10-15 seconds, stirring halfway through to ensure even warming. Be cautious not to overheat, as the mayonnaise base can separate.
Alternatively, transfer the sauce to a small saucepan. Warm over low heat, stirring continuously until it reaches the desired temperature. This method helps maintain the smooth texture of the sauce.
For a more controlled approach, use a double boiler. Place the sauce in a heatproof bowl set over a pot of simmering water. Stir gently until warmed through. This gentle heat prevents the sauce from breaking.
If you prefer a cold dip, simply let the sauce sit at room temperature for about 15-20 minutes before serving. This takes the chill off without altering the consistency.
