In a small bowl, combine the mayonnaise, ketchup, and prepared horseradish.
Add the paprika, oregano, black pepper, and cayenne pepper to the bowl.
Stir well until all ingredients are fully combined and the sauce is smooth.
Serve with onion rings, onion petals, or your favorite fried appetizer.
Store in an airtight container in the refrigerator for up to 5 days. No reheating needed; serve cold or at room temperature.
Yes, mix the sauce up to 2 days in advance and refrigerate in an airtight container. The flavors actually deepen overnight.
Fresh grated horseradish works but is much spicier; start with 1 tsp. Wasabi paste offers similar heat. Neither will taste identical.
Traditional mayo contains eggs; use vegan mayo to make this sauce vegan and dairy-free.
Reduce cayenne and horseradish for milder heat, or add extra cayenne and paprika for a bolder kick.
This sauce works well with French fries, fried chicken tenders, calamari, and breaded vegetables.
