Ingredients Equipment Method Notes

Ingredients

  

• 1/2 cup mayonnaise
• 2 tablespoons ketchup
• 1.5 teaspoons prepared horseradish or to taste
• 1/4 teaspoon smoked paprika
• 1/4 teaspoon garlic powder
• 1/4 teaspoon dried oregano
• 1/8 teaspoon cayenne pepper
• 1 pinch salt

Equipment

• mixing bowl
• whisk

Method

 

1. Add the mayonnaise, ketchup, and horseradish to a small bowl.
2. Stir in the smoked paprika, garlic powder, oregano, cayenne, and salt.

Notes

Prepared horseradish is the star here - adjust the amount to control the kick. Letting the sauce chill an hour gives the most authentic flavor.

Tips for the Best Bloomin’ Onion Sauce

• Use prepared horseradish, not horseradish cream, for the strongest flavor
• Chill at least 30 minutes so the spices fully bloom
• Add cayenne a pinch at a time to control the heat
• Double the batch – it disappears fast at parties

Storage & Reheating

Store in an airtight container in the refrigerator for up to 1 week. Stir before serving.

Variations to Try

• Add a teaspoon of Dijon for extra tang
• Stir in a dash of Worcestershire for depth
• Use sriracha in place of cayenne for a different heat profile
