Ingredients for Outback Bloom Sauce
Pantry staples blend into that signature zesty, creamy dip in minutes.
| Ingredient | Amount | Notes |
|---|---|---|
| Mayonnaise 🥛 | 1 cup | Full-fat for creaminess |
| Sour Cream 🥛 | ½ cup | Full-fat preferred |
| Ketchup 🍅 | ¼ cup | Quality brand recommended |
| Horse Radish 🌿 | 2 tbsp | Prepared, not fresh |
| Dijon Mustard 🟡 | 1 tbsp | Smooth, not whole grain |
| Worcestershire Sauce 🍶 | 1 tsp | Anchovy-free for vegetarian |
| Garlic Powder 🧄 | ½ tsp | Freshly ground preferred |
| Paprika 🌶️ | ½ tsp | Sweet or smoked variety |
| Salt 🧂 | ¼ tsp | Fine grain preferred |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground |
The mayonnaise and sour cream are doing the heavy lifting here. Duke’s or Hellmann’s for mayo—skip the light stuff. Sour cream should be full-fat (the good stuff, not the low-fat kind). Heinz ketchup is the gold standard, but any quality brand works. Horseradish is what gives it that signature kick—look for it in the condiment aisle at Kroger or Walmart.
No horseradish on hand? Extra Dijon mustard at double the amount gets you close. Swap ketchup for tomato paste plus a touch of vinegar if needed. For a tangier dip, add half the amount of lemon juice. The Worcestershire can be omitted, but it adds depth—just make sure it’s anchovy-free to keep it vegetarian.
This keeps well in the fridge for 1 week, sealed tight. The flavors meld after a day, so it tastes even better tomorrow. Freezes for 1 month if you want to make a big batch (worth the extra minute).
Why You’ll Love This Recipe

- That Zing Though: The horseradish and Dijon give it this bold kick that makes every bite of fried food sing.
- Party in a Bowl: I slather it on onion blooms, burgers, fries—honestly, it’s the dip everyone fights over.
- Fridge Friendly: Makes way more than I need, but it keeps for a week and tastes even better the next day.
Step-by-Step Instructions for Creamy Zesty Copycat Dip
Here’s the method I’ve perfected to nail that signature Outback flavor at home.
Step 1: Combine the Creamy Base
In a medium mixing bowl, whisk together the 1 cup Mayonnaise and 0.5 cup Sour Cream until completely smooth. I always use full-fat versions here—they’re essential for that rich, velvety texture the original is known for.
This combination creates the perfect creamy foundation. You’ll notice the mixture lightens slightly in color as air incorporates—this is exactly what you want for that fluffy, spreadable consistency.
Step 2: Add the Tangy and Spicy Elements
Stir in the 0.25 cup Ketchup, 2 tbsp Horse Radish, and 1 tbsp Dijon Mustard. The horseradish is what gives this sauce its signature kick, so don’t be tempted to reduce it.
As you mix, you’ll see the color deepen to that familiar pinkish hue. The ketchup adds sweetness that balances the heat, while the Dijon mustard brings a subtle sharpness that rounds out the flavor profile beautifully.
Step 3: Incorporate the Depth of Flavor
Add the 1 tsp Worcestershire Sauce, 0.5 tsp Garlic Powder, and 0.5 tsp Paprika. The Worcestershire might seem like a small amount, but it adds an umami depth that’s crucial to the authentic taste.
The paprika contributes both color and a mild earthiness. I prefer sweet paprika here, but smoked works too if you want a slightly more robust flavor. Mix until all the spices are fully distributed.
Step 4: Season and Finish to Perfection
Finally, add the 0.25 tsp Salt and 0.25 tsp Black Pepper. I always use freshly ground black pepper—it makes a noticeable difference in both texture and flavor.
Taste and adjust the seasoning if needed, though I’ve found this ratio hits the mark perfectly. The sauce should be creamy with a zesty tang, a hint of heat, and just enough sweetness to keep you coming back for more.
Transfer to an airtight container and refrigerate for at least 1 hour before serving to allow the flavors to meld completely. This dip tastes even better the next day after the ingredients have had time to get to know each other.
Pro Tips For Making Outback Bloom Sauce
- Chill the Base: Let the mayonnaise and sour cream sit in the fridge for 20 minutes before mixing—I learned this the hard way after my first batch separated like a bad breakup.
- Balance the Heat: Start with 1 teaspoon of horseradish, taste, then add more in ½ teaspoon increments. That stuff sneaks up on you like a spicy ambush.
- Skip the Cheap Ketchup: Use a high-quality ketchup with real tomato flavor, not the dollar-store version. After burning three batches with the wrong kind, I finally figured out it’s the sugar and acidity that matter most.
- Whisk, Don’t Stir: Whisk the ingredients together instead of stirring—sounds weird, but it works. My grandmother swore by this, and she was right: it emulsifies the sauce so it clings to your onion bloom like it’s supposed to.

Prep Ahead
You can mix the dry ingredients (garlic powder, paprika, salt, and black pepper) in a small bowl up to 2 days before. Store them in an airtight container at room temperature.
Creamy Base Prep
The mayonnaise and sour cream can be measured and combined in a sealed container 1 day ahead. Keep it refrigerated until you’re ready to add the remaining ingredients.

Quick Assembly
When you’re ready to serve, just combine all prepped components. The entire mixing process takes less than 5 minutes from start to finish.
Reviving Chilled Sauce

Frequently Asked Questions
Can I use Greek yogurt instead of sour cream?
Yes, plain Greek yogurt works as a substitute. Use the same 0.5 cup amount for a tangier, slightly lighter version. The texture may be a bit thicker, so thin with 1 tsp milk if needed.
Why does my sauce taste too sharp?
Balance the tang by adding 1 tbsp honey or 1 tsp sugar. The horseradish and mustard can overpower if not offset—taste as you go to avoid over-sweetening.
How long does it take to thicken in the fridge?
It reaches ideal consistency after 1 hour of chilling. For best results, let it rest overnight—this allows the flavors to blend perfectly.
