Ingredients List for the Best Homemade Mayonnaise Recipe for Potato Salad

The foundation of the best homemade mayonnaise recipe for potato salad is just a handful of simple, quality ingredients. Using fresh, room-temperature components is the key to a smooth, stable emulsion.

• 1 large egg yolk, at room temperature
• 1 teaspoon Dijon mustard
• 1 tablespoon white wine vinegar or fresh lemon juice
• ½ teaspoon fine sea salt
• 1 cup neutral oil (like avocado, grapeseed, or a light olive oil)
• 1-2 teaspoons warm water (optional, for adjusting consistency)

Smart Swaps: For a different flavor profile, try apple cider vinegar. If you only have extra virgin olive oil, use half neutral oil and half EVOO to avoid a bitter taste. This basic formula is also your gateway to countless mayonnaise recipes dishes, from aioli to herbed spreads.

Timing for Your Homemade Mayo

• Prep Time: 5 minutes
• Cook Time: 0 minutes
• Total Time: 5 minutes

Yes, you read that right. In less time than it takes to find a jar in the fridge, you can have fresh, superior-tasting mayo. This process is about 100% faster than a trip to the store, and the flavor payoff is immediate.

Step-by-Step Instructions for Homemade Mayonnaise

Creating your own mayonnaise is a simple process of slow, steady emulsification. Follow these steps for perfect results every time.

1. Combine the Base: In a medium bowl (or the cup of an immersion blender), whisk together the egg yolk, Dijon mustard, vinegar or lemon juice, and salt until completely smooth and slightly pale.
2. Start the Emulsion: While whisking constantly, begin adding the oil drop by drop. This is the most critical step. Go painfully slow at first—just a few drops at a time—and whisk vigorously until each addition is fully incorporated. Pro Tip: If you have an immersion blender, this process is foolproof and takes seconds.
3. Stream in the Oil: Once the mixture has thickened and looks creamy (after about ¼ cup of oil), you can start adding the remaining oil in a very thin, steady stream while continuing to whisk non-stop.
4. Adjust and Season: Once all the oil is incorporated, you should have a thick, luxurious mayonnaise. Taste and adjust salt or acidity as needed. If it’s too thick for your potato salad, whisk in a teaspoon or two of warm water to loosen it to the perfect, creamy consistency for coating potatoes.

Nutritional Information

A 1-tablespoon serving of this homemade mayonnaise contains approximately 100 calories, 11g of fat (primarily from your chosen oil), 0g carbohydrates, and 0g protein. Because you control the ingredients, you avoid the added sugars and preservatives found in many store brands. The egg yolk provides choline, which supports brain health.

Equipment Needed

You don’t need fancy gear for this best homemade mayonnaise recipe for potato salad. Either of these methods works beautifully:

• A whisk and a medium bowl: The traditional, arm-strengthening method. Use a bowl with a non-slip base or place it on a damp kitchen towel to keep it steady.
• An immersion blender and its tall cup: The modern, nearly-instant method. This tool makes the emulsion process incredibly easy and consistent.
• A measuring spoon and cup: For accuracy.
• A bottle with a narrow pour spout for the oil (helpful but not essential): Makes streaming the oil much easier.

Why You’ll Love This Recipe

1. Unbeatable Flavor & Texture: The fresh, clean taste and creamy, velvety texture are miles ahead of any jarred product. It makes your potato salad truly exceptional.
2. Total Control: You decide the salt level, the tang (more lemon? more vinegar?), and the type of oil. No mystery ingredients.
3. Incredibly Fast: Five minutes from start to finish for a condiment that elevates everything it touches.
4. A Foundation Recipe: Master this, and you can create garlic aioli, herbed mayo for sandwiches, or the base for a creamy dressing like the one in our Creamy Ranch Pasta Salad.

Healthier Alternatives

This homemade mayo recipe is easily adaptable to different dietary needs.

• Lighter Option: Substitute up to half of the oil with a mild, plain Greek yogurt for a tangy, protein-boosted spread.
• Different Oil Profiles: Use all or part avocado oil for its monounsaturated fats and high smoke point, which is great if you plan to use the mayo in a cooked application like a mayonnaise chicken recipe.
• Egg-Free: For an egg-free version, you can use the brine from a can of chickpeas (aquafaba) as an emulsifier, though the technique and consistency will differ.

Serving Suggestions

Of course, this mayonnaise is the crowning glory for classic potato salad. But its uses are endless:

• As a Sandwich Spread: It’s the perfect base for a BLT or chicken salad sandwich.
• In Other Salads: Use it to bind a Lemon Dill Salmon Salad or to create the dressing for a Dill Pickle Pasta Salad.
• As a Dip or Aioli Base: Stir in roasted garlic, fresh herbs, or a pinch of smoked paprika for a quick dip for fries or veggies.
• With Grilled Meats: A dollop on grilled chicken or fish adds instant moisture and flavor.

Common Mistakes to Avoid

1. Adding the Oil Too Fast: This is the number one reason for a broken mayonnaise. If the oil isn’t slowly emulsified, the mixture will separate. Start with drops, not a stream.
2. Using Cold Ingredients: Cold egg yolks and oil are harder to emulsify. Let everything sit on the counter for 20-30 minutes before starting.
3. Not Whisking Enough: You need to whisk vigorously, especially at the beginning, to create that initial stable emulsion. Don’t be timid.
4. Over-Salting Early: Season at the end. The flavor concentrates as you whisk, so it’s easier to adjust once the mayo is fully formed.

Storing Tips for Your Homemade Mayonnaise

• Refrigeration: Store your homemade mayonnaise in a clean, airtight container in the refrigerator. It will keep for up to 1 week.
• Safety First: Because it contains a raw egg yolk, always keep it refrigerated and use it within the week. If you have concerns, you can use pasteurized eggs.
• Freezing: Freezing is not recommended, as it will likely cause the emulsion to break and separate when thawed.
• Reviving Broken Mayo: If your mayonnaise breaks or looks curdled, don’t panic. Place a fresh egg yolk in a clean bowl and very slowly whisk in the broken mayonnaise, as if it were the oil. It should come back together beautifully.
