Health Benefits & Nutrition

Mustard mayo doesn’t just taste amazing—it also offers certain nutritional perks. The mustard provides antioxidants, which studies from the American Chemical Society have shown help reduce inflammation and support heart health. Mustard seeds contain compounds like glucosinolates that may aid digestion and promote metabolic health. Meanwhile, mayonnaise, made primarily from oils, supplies healthy fats vital for brain function and energy. Sour cream adds calcium and vitamin B12, supporting bone strength and the nervous system. Keep in mind, those with mustard allergies should avoid this recipe, and it’s best to consume in moderation due to the calorie density.

Full Ingredient List

• 1 ½ cups good-quality mayonnaise
• 3 tablespoons Dijon mustard
• 1 ½ tablespoons whole-grain mustard
• ⅓ cup sour cream
• ¼ teaspoon kosher salt

Equipment Needed

• Medium mixing bowl
• Whisk or fork
• Measuring cups and spoons
• Spatula for scraping (optional)

Tips for Choosing Quality Ingredients

Use a mayonnaise with a clean ingredient list—look for versions made with non-GMO oils and free of preservatives. Dijon mustard should have a bright, slightly spicy aroma; avoid those heavily vinegared or artificial tasting. For whole-grain mustard, seeds must be plump and intact for that delightful crunch. Sour cream works best when fresh and thick, lending creaminess without excess tang. Kosher salt is preferred for its purity and flaky texture, but you can substitute with sea salt if needed.

Step-by-Step Instructions

Step 1: Measure and Combine Ingredients (2 minutes)

Place 1 ½ cups of mayonnaise, 3 tablespoons Dijon mustard, and 1 ½ tablespoons whole-grain mustard into a medium bowl.

Step 2: Add Sour Cream (1 minute)

Add ⅓ cup of sour cream to the mixture.

Step 3: Season With Salt (30 seconds)

Sprinkle ¼ teaspoon kosher salt evenly over the ingredients.

Step 4: Whisk Until Smooth and Creamy (1.5 minutes)

Using a whisk, blend all components thoroughly until you achieve a creamy, even texture. Make sure no streaks remain.

Step 5: Serve or Refrigerate (Immediately)

Let the mustard mayo sit at room temperature for 10 minutes to maximize flavor or refrigerate for up to 1 hour before serving.

Variations & Substitutions

• Spicy Kick: Add 1 teaspoon of hot sauce or a pinch of cayenne pepper for a fiery twist.
• Greek Yogurt Swap: Replace sour cream with Greek yogurt for a protein-rich, tangier option without sacrificing creaminess.
• Honey Mustard Mayo: Stir in 1 tablespoon honey to bring a sweet balance to the tangy mustard flavors.
• Vegan Version: Substitute mayonnaise and sour cream with plant-based alternatives like vegan mayo and cashew cream.
• Herb Infusion: Mix in 1 tablespoon chopped fresh dill or tarragon for an aromatic lift.

Storage & Shelf Life

Store mustard mayo in an airtight container in the refrigerator for up to 5 days. Keep it chilled to preserve freshness and prevent separation. Although freezing is not recommended—since mayonnaise can separate and become grainy—you can prepare small batches to avoid waste. Check for spoilage signs like off odors, discoloration, or watery consistency before using, and discard if any appear.

Pro Tips

• Whisk gently but thoroughly to combine without breaking the mayonnaise’s emulsification, which keeps your mustard mayo creamy and smooth.
• If the mixture feels too thick, thin it down with a teaspoon of milk or water, whisking slowly to retain creaminess.
• To prevent staining your utensils from the yellow mustard, rinse immediately after use or use silicone tools that are easier to clean.
• Room temperature ingredients blend faster and more evenly, so allow mayo and sour cream to warm slightly before mixing.
