I tested this formula across several brands of mayonnaise and relishes and found the end result varies subtly. Using a full-flavor mayonnaise and a finely chopped sweet relish yields the creamiest mouthfeel and cleanest balance. My partner declared it superior to store-brand burger sauces and friends at a backyard cookout asked for the recipe on the spot.
Ingredients
- Mayonnaise: 1 cup of a full-flavor mayonnaise such as Hellmann's or Duke's provides the rich, creamy base. Choose a brand you enjoy since this is two thirds of the final volume and defines mouthfeel.
- Sweet pickle relish: 2 tablespoons of classic sweet relish adds bright sweetness and texture. Use a finely chopped relish for even distribution or chop larger relish slightly for visible pickle bits.
- Ketchup: 2 tablespoons of a tomato ketchup like Heinz adds sweetness and familiar tang while deepening color. Low-sugar versions will reduce sweetness slightly.
- Dijon mustard: 2 teaspoons contributes a sharp, vinous note that cuts through the richness. Grey Poupon style Dijon is ideal for its balanced acidity.
- Montreal steak seasoning: 1/2 teaspoon introduces garlic, black pepper, and coriander for savory complexity. If you do not have this blend use 1/4 teaspoon garlic powder and 1/4 teaspoon coarse black pepper.
- Smoked paprika: 1/2 teaspoon gives a warm, smoky aroma without heat. Opt for Spanish smoked paprika for the cleanest smoke flavor.
- Worcestershire sauce: 1/4 teaspoon finishes the sauce with umami depth. Note that many Worcestershire sauces contain anchovy so it adds subtle savory richness rather than fishiness when used sparingly.
Instructions
Combine Ingredients: Place 1 cup mayonnaise, 2 tablespoons sweet pickle relish, 2 tablespoons ketchup, 2 teaspoons Dijon mustard, 1/2 teaspoon Montreal steak seasoning, 1/2 teaspoon smoked paprika, and 1/4 teaspoon Worcestershire sauce into a small mixing bowl. Measure carefully using standard U.S. cups and measuring spoons to keep the balance consistent. Emulsify and Adjust: Stir the mixture vigorously with a small whisk or spoon until completely smooth. Taste and adjust: add a pinch more relish for sweetness, an extra 1/4 teaspoon Dijon for acidity, or a few grinds of black pepper if you prefer more bite. The goal is a smooth, homogenized texture with tiny bits of pickle evenly spread. Chill and Marry: Transfer the sauce to an airtight container and refrigerate for at least 30 minutes so the flavors meld. Stir again just before serving to reincorporate any settled juices and check seasoning once more. The sauce will thicken slightly as it chills.
You Must Know
- This mixture keeps well in the refrigerator for up to 2 weeks in a sealed container. Freeze is not recommended as the texture separates on thawing.
- High in fat and calories per serving because mayonnaise is the main ingredient. Use sparingly if tracking macronutrients or swap for reduced fat mayonnaise to cut calories.
- Worcestershire sauce contains anchovy in most brands so it is not strictly vegan and may affect people with fish allergies.
- The sauce is naturally gluten free when you choose gluten free ketchup and Worcestershire sauce; verify labels if you have strict requirements.
My favorite aspect of this sauce is how adaptable it is. At a family barbecue, doubling the recipe and serving it in a wide bowl where guests could spoon their own helped it disappear fast. Small changes like adding a dash of hot sauce or subbing sweet relish for chopped bread-and-butter pickles yield new profiles without losing the original charm.
Storage Tips
Store the sauce in an airtight glass jar or plastic container in the refrigerator. Glass is preferable because it does not absorb odors and is easier to clean. Keep the container in the main body of the refrigerator rather than the door to maintain a steady temperature. Label with the preparation date and use within 14 days. To rejoin any separation, stir vigorously or whisk briefly before serving. Do not freeze as mayonnaise will become grainy and separate when thawed.
Ingredient Substitutions
If you are avoiding eggs, substitute the regular mayonnaise with an egg-free commercial plant-based mayonnaise using a one-to-one ratio. For a lower calorie option, choose a light mayonnaise but be aware the sauce will be thinner and less rich. If you lack Montreal steak seasoning, combine 1/4 teaspoon garlic powder with 1/4 teaspoon coarsely ground black pepper and a pinch of coriander. Replace smoked paprika with a small pinch of liquid smoke if you prefer a more pronounced smoke note but use sparingly to avoid overpowering the sauce.
Serving Suggestions
Use this sauce as a spread on toasted burger buns and as a dip for thick-cut fries or sweet potato wedges. It makes an excellent complement to grilled chicken sandwiches and fried fish tacos where the creamy sweetness balances the savory protein. For a simple party dip, combine equal parts sauce and sour cream or Greek yogurt and serve with crudites and chips. Garnish platters with chopped chives or thinly sliced pickles to mirror the sauce flavors.
Cultural Background
The concept of a creamy, tangy burger sauce has roots in diner and drive-in traditions across the United States where house-made condiments define an establishment s character. This particular assembly borrows elements from classic American burger dressings and remoulades with added smoky paprika to emulate the grilled flavor of a smash burger. Relish and ketchup bring sweetness and familiarity while mustard and Worcestershire add sharpness and umami, a combination that has made such sauces ubiquitous on regional burger menus.
Seasonal Adaptations
In summer, stir in finely chopped fresh dill and swap sweet relish for finely chopped fresh dill pickles to add brightness. For autumn and winter pairings, add a pinch of ground chipotle or a teaspoon of maple syrup for warming complexity that pairs well with roasted root vegetables. At holiday gatherings, increase Dijon to 1 tablespoon and add a teaspoon of whole grain mustard for a more robust profile that complements roasted meats and hearty sandwiches.
Meal Prep Tips
Make a double batch and portion into small jars so you have grab-and-go condiments for the week. Keep jars in the fridge and use within two weeks. If preparing a sandwich spread for lunches, assemble sandwiches the night before and store components separately to maintain bun texture; spread the sauce just before eating for the best texture. Use shallow airtight containers to speed chilling if you need the sauce cooled quickly.
This sauce is about joy and convenience as much as flavor. It elevates simple ingredients into a consistent, reliable condiment that can become part of your everyday cooking rhythm. Try it on a warm, butter-toasted bun and see how quickly it becomes a staple in your kitchen.
Pro Tips
Measure mayonnaise and relishes with standard U.S. measuring cups and spoons to keep balance consistent.
Chill the sauce at least 30 minutes so flavors meld and the texture firms up slightly.
Use a full-flavor mayonnaise for best mouthfeel and richness, or swap for light mayo if reducing calories.
Stir well before using if any liquid separates after refrigeration.
For finer texture, pulse the relish briefly in a food processor before mixing.
This nourishing smashburger signature creamy sauce recipe is sure to be a staple in your kitchen. Enjoy every moist, high protein slice — it is perfect for breakfast or as a wholesome snack any time.
