Few condiments are as simple yet as transformative as mayonnaise. Luxuriously creamy, versatile, and endlessly adaptable, homemade mayonnaise elevates any dish — from sandwiches and salads to grilled meats and seafood. While jars on the supermarket shelf are convenient, there’s nothing quite like the fresh flavor and silky texture of a mayo you make yourself.

What Is Mayonnaise?

At its core, mayonnaise is an emulsion: the blending of two ingredients that don’t naturally mix — oil and egg yolk — brought together by whisking or blending. Add a splash of acid (like lemon juice or vinegar), a touch of salt, and you have the foundation of one of the world’s most beloved sauces.

What Are the Ingredients in Mayonnaise?

The classic recipe is minimal, which makes ingredient quality essential:

  • 1 large egg yolk, room temperature
  • 1 cup neutral oil (canola, grapeseed, or sunflower)
  • 1 tsp Dijon mustard
  • 1 tsp white wine vinegar or fresh lemon juice
  • Pinch of salt

From this base, you can experiment with different oils or flavors, giving your mayonnaise a unique twist.

How Do You Make Mayonnaise at Home? 

Traditionally, mayonnaise is whisked by hand, but for flawless emulsification and chef-level speed, an immersion blender is ideal.

The All-Clad Stainless Steel Immersion Hand Blender, 600 Watts is a perfect tool here. Its variable-speed control and turbo function create a stable emulsion in seconds, while the extra-long driveshaft easily reaches into mixing jars or deep bowls. Cleanup is effortless thanks to the detachable stainless shaft, and the large blending head minimizes splatter.

Directions

  1. In a tall container, add the egg yolk, mustard, vinegar, and salt.
  2. Place the immersion blender at the bottom of the container.
  3. With the blender running, slowly drizzle in the oil. The emulsion forms almost instantly.
  4. Blend until thick and creamy, adjusting seasoning with more lemon juice or salt to taste.

Mayo with Olive Oil & Avocado Oil Mayonnaise

Different oils yield different flavors. Olive oil adds richness and depth, while avocado oil produces a light, slightly nutty mayonnaise — perfect for those seeking a healthier fat alternative. Experiment by substituting all or part of the neutral oil with these options.

Recipes for Mayonnaise

Mayonnaise is more than a sandwich spread. Use it to:

  • Create aioli by adding roasted garlic.
  • Blend into a creamy coleslaw dressing.
  • Mix with herbs for a quick green goddess sauce.
  • Pair with Sriracha for a spicy dipping sauce.

Substitute for Mayonnaise

Out of eggs? Try a vegan mayonnaise with aquafaba (chickpea liquid) as the base. The texture is surprisingly similar and makes an excellent substitute for traditional mayo in most recipes.

How Long Does Homemade Mayonnaise Last?

Stored in an airtight container in the refrigerator, homemade mayonnaise lasts about 3–5 days. Always use fresh eggs and clean utensils to maximize food safety.

Chef Tips for Perfect Homemade Mayonnaise

  • Use room-temperature ingredients: Cold eggs can cause the emulsion to break.
  • Add oil slowly: Especially at the beginning, drizzle in oil gradually for stability.
  • Adjust the flavor: Balance richness with acidity — lemon zest or champagne vinegar are great upgrades.
  • Experiment with aromatics: Fresh herbs, chili paste, or smoked paprika can turn mayo into a gourmet sauce.

Mayonnaise may be humble, but in the hands of a chef — and with the right tools like All-Clad’s Immersion Blender — it becomes an essential building block of modern cooking. Once you’ve mastered homemade mayo, you’ll never look at the store-bought version the same way again.
