Ingredients You’ll Need
This recipe comes together with a few simple pantry staples. Here’s what you’ll need:

- Mayonnaise: This forms the creamy base of the sauce. Use a good quality, full-fat mayonnaise for the best flavor and texture.
- Ketchup: Adds a touch of sweetness, tang, and color.
- Prepared Horseradish: This is the key ingredient for that signature zesty kick. Use the kind found in the refrigerated section for the best flavor.
- Spices: A specific blend of paprika, garlic powder, onion powder, and a pinch of cayenne pepper creates the sauce’s unique savory and slightly spicy profile.
- Salt and Black Pepper: To taste, to enhance all the other flavors.
How to Make Bloomin Onion Sauce Step-by-Step
Making this sauce couldn’t be simpler. Follow these two easy steps:
- Combine Ingredients: In a medium bowl, add the mayonnaise, ketchup, and prepared horseradish. Whisk them together until they are smooth and fully combined.
- Add Spices and Chill: Add the paprika, garlic powder, onion powder, cayenne pepper, salt, and black pepper to the bowl. Whisk again until all the spices are evenly distributed and the sauce is a uniform pale orange color. For best results, cover the bowl and refrigerate for at least 30 minutes to allow the flavors to meld together.
Tips for the Best Dipping Sauce
A few simple tips can take your sauce from great to absolutely perfect.

- Let it Chill: Don’t skip the chilling step! Letting the sauce rest in the fridge for at least 30 minutes (or even a few hours) is crucial. This gives the spices time to bloom and meld into the creamy base, creating a much deeper and more cohesive flavor.
- Adjust the Heat: If you like it extra spicy, add another pinch of cayenne pepper. If you’re sensitive to heat, you can reduce or omit it. The recipe is easily customizable to your taste.
- Use Fresh Spices: Make sure your spices, especially paprika and garlic powder, are fresh. Older spices lose their potency and won’t deliver the bold flavor this sauce is known for.
Delicious Ways to Serve Your Sauce
While it’s the perfect partner for a homemade Bloomin’ Onion, this sauce is incredibly versatile. Think of it as an all-purpose zesty dip or spread! Try it with:
- French fries, tater tots, or sweet potato fries
- Crispy onion rings
- As a dipping sauce for chicken tenders or wings
- Spread on burgers, wraps, or sandwiches for a zesty kick
- A fantastic dip for fried shrimp or zucchini sticks
- Drizzled over Air Fryer Broccoli or roasted potatoes
It’s also a star on an appetizer platter. Pair it with a creamy bacon cheddar ranch dip for the ultimate party spread.
How to Store Homemade Bloomin Onion Sauce
Storing your sauce is easy. Transfer it to an airtight container, like a mason jar or a small Tupperware, and keep it in the refrigerator. When stored properly, the sauce will stay fresh and delicious for up to one week. Give it a quick stir before serving each time, as it may separate slightly upon sitting.
Recipe Variations to Try
Want to customize your sauce? Here are a few simple variations:
- Smoky Bloomin Onion Sauce: Add 1/4 teaspoon of smoked paprika along with the regular paprika for a delicious, smoky depth.
- Spicy Chipotle Version: For a different kind of heat, add 1/2 teaspoon of adobo sauce from a can of chipotle peppers.
- Without Horseradish: If you’re not a fan of horseradish, you can leave it out. The sauce will be less zesty but still creamy and delicious. You can add a small squeeze of lemon juice to add back some tang. Using this with a good fried chicken batter recipe will make for an amazing meal.
