Ingredients
- 1/2 cup mayonnaise (regular or light)
- 2 tablespoons ketchup
- 1 tablespoon prepared horseradish (not cream-style; adjust to taste)
- 1 teaspoon Dijon mustard (or yellow mustard for a milder bite)
- 1/2 teaspoon paprika (smoked paprika if you want a smoky note)
- 1/4 teaspoon garlic powder
- 1/4 teaspoon onion powder
- 1/8–1/4 teaspoon cayenne pepper (optional, for heat)
- 1/4 teaspoon ground black pepper
- 1/4 teaspoon kosher salt (or to taste)
- 1 teaspoon apple cider vinegar (or lemon juice)
- 1/2 teaspoon sugar (or honey; optional, balances the tang)
How to Make It
- Mix the base: In a small bowl, whisk together the mayonnaise, ketchup, horseradish, and Dijon mustard until smooth.
- Add spices: Stir in the paprika, garlic powder, onion powder, cayenne, black pepper, and salt. Whisk until evenly combined.
- Balance the flavor: Add the apple cider vinegar and sugar. Mix well, then taste and adjust seasoning as needed.
- Chill for best flavor: Cover and refrigerate for at least 30 minutes, ideally 2 hours.This lets the flavors meld and the sauce thicken slightly.
- Serve: Stir once more before serving with a Bloomin’-style onion, fries, onion rings, chicken tenders, or a veggie plate.
How to Store
- Refrigerate: Keep the sauce in an airtight container in the fridge for up to 5–7 days.
- No freezing: Mayo-based sauces don’t freeze well. They can separate and turn grainy.
- Stir before using: If it settles or separates slightly, just give it a quick stir.
- Food safety note: Use clean utensils and don’t double-dip to extend freshness.
Health Benefits
- Portion control: Making it at home lets you manage serving size and ingredients, which can help keep calories in check.
- Customizable: You can use light mayo or Greek yogurt to reduce fat, and adjust sugar and salt to suit your needs.
- Flavor-packed: Spices like paprika, garlic, and onion powder add bold flavor without many calories.
- Potential swaps: With yogurt or avocado oil mayo, you can boost protein or healthy fats while keeping the taste.
What Not to Do
- Don’t skip the chill time: The sauce tastes sharper and less balanced before it rests.
- Don’t use cream-style horseradish: It’s too mild and adds extra dairy, which dulls the flavor.
- Don’t overdo the vinegar: Too much acid can thin the sauce and overpower the spices.
- Don’t rely on smoked paprika if you want the classic taste: It’s tasty but changes the profile. Use regular paprika for the original style.
- Don’t forget to taste as you go: Horseradish brands vary in heat, so adjust carefully.
Recipe Variations
- Spicier version: Add more horseradish, increase cayenne to 1/2 teaspoon, and stir in a few dashes of hot sauce.
- Smoky twist: Use smoked paprika and a tiny drop of liquid smoke (go easy—just 1–2 drops).
- Lighter option: Swap half or all of the mayo for plain Greek yogurt. Add an extra pinch of sugar or honey to balance the tang.
- Sweet heat: Add 1 teaspoon honey and a pinch of chipotle powder for a sweet-smoky finish.
- Garlic lovers: Increase garlic powder to 1/2 teaspoon, or add a small grated garlic clove for a sharper bite.
- No horseradish on hand: Use 1–2 teaspoons prepared mustard and a pinch of wasabi powder as a stand-in. The flavor won’t be identical, but it keeps the heat and tang.
FAQ
Can I make this ahead?

Use prepared horseradish, not cream-style. Prepared horseradish is just grated horseradish in vinegar and packs the right punch without extra dairy.
Is this the exact Outback recipe?
No. This is a home-style imitation based on common ingredients and flavor testing.
It’s very close in taste and texture.
Can I use Miracle Whip instead of mayonnaise?
You can, but it will be sweeter and tangier, which shifts the flavor. If you use it, reduce or omit the sugar and adjust the vinegar to taste.
How do I thicken the sauce if it’s too thin?
Add a spoonful more mayo and a small pinch of onion powder. Chill for 20–30 minutes—cold temperatures help it set up.

It’s great with fries, onion rings, sweet potato fries, chicken tenders, fried shrimp, burgers, and roasted vegetables.
It also makes a tasty spread for sandwiches and wraps.
Can I make it dairy-free or gluten-free?
Yes. Most versions are naturally dairy-free and gluten-free if your mayo, ketchup, and mustard are certified. Check labels to be safe.
How spicy is it?
Mild to medium, depending on your horseradish and cayenne.
Start small and add more heat as you like.
Can I use lemon juice instead of vinegar?
