Jump to RecipeTrader Joe’s Magnifisauce Ingredients
- 1 cup mayonnaise (like Trader Joe’s Real Mayonnaise)
- ¼ cup ketchup (like Trader Joe’s Organic Ketchup)
- 2 tablespoons sweet pickle relish
- 1 tablespoon distilled white vinegar
- 1 teaspoon granulated sugar
- ½ teaspoon paprika
- ½ teaspoon onion powder
- ½ teaspoon garlic powder
- Sea salt and freshly ground black pepper, to taste
How To Make Trader Joe’s Magnifisauce
- Combine Ingredients: In a medium bowl, combine the mayonnaise, ketchup, sweet pickle relish, white vinegar, sugar, paprika, onion powder, and garlic powder.
- Mix and Season: Whisk everything together until the sauce is completely smooth and has a uniform pale orange color. Season to your taste with a pinch of salt and freshly ground black pepper.
- Chill and Serve: For the best flavor, cover the bowl and refrigerate the sauce for at least 30 minutes to allow all the flavors to meld together.

Recipe Tips
- How to get the best flavor? The most important secret is to let the sauce chill for at least 30 minutes before serving. This is a non-negotiable step that allows the flavors from the spices and relish to fully infuse the creamy base, creating a much more delicious and cohesive sauce.
- Can I make this ahead of time? Absolutely! This sauce is a perfect make-ahead condiment. In fact, it’s even better when made a day in advance.
- How can I customize the flavor? This is a great base recipe. If you prefer a tangier sauce, you can use dill pickle relish instead of sweet. For a little bit of heat, add a few dashes of your favorite hot sauce or a pinch of cayenne pepper.
- How to get the smoothest sauce? If your sweet pickle relish is very chunky, you can give it a finer chop before adding it to the bowl, or simply pulse all the ingredients together in a small food processor for a completely smooth, restaurant-style sauce.
