Ingredients List for the Best Homemade Mayonnaise Recipe for Tuna Salad

This best homemade mayonnaise recipe for tuna salad relies on simple, quality ingredients you likely already have. The magic is in their freshness and how you bring them together.

• 1 large egg yolk, at room temperature
• 1 teaspoon Dijon mustard
• 1 tablespoon fresh lemon juice
• 1 teaspoon white wine vinegar
• ¼ teaspoon fine sea salt, plus more to taste
• 1 cup neutral oil (like avocado, light olive, or grapeseed), divided

Smart Swaps & Notes:

• Mustard: Dijon adds a subtle, complex flavor, but yellow mustard works in a pinch.
• Acid: All lemon juice or all vinegar is fine. Apple cider vinegar adds a nice fruity note.
• Oil: A neutral oil is key for that classic mayo flavor. Using extra virgin olive oil will make a stronger, more pungent aioli, which is delicious but distinct.
• For a Keto Mayonnaise Recipe: This recipe is naturally keto-friendly. Just ensure your mustard and vinegar are sugar-free.

Timing

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

That’s it. In less time than it takes to find your keys, you can have a jar of fresh, superior mayo. It’s about 90% faster than driving to the store, and infinitely more satisfying.

Step-by-Step Instructions

Making mayo can feel intimidating, but with a steady hand and these simple steps, you’ll have a perfect emulsion every time. Regular kitchen, regular time, great results.

1. Combine the Base: In a medium bowl (or the cup of your immersion blender), whisk together the egg yolk, Dijon mustard, lemon juice, vinegar, and salt until completely smooth and slightly pale.
2. Start the Emulsion: While whisking constantly and vigorously, begin adding the oil drop by drop. This is the most critical step. Go painfully slow at first. You’re building the foundation for a thick, stable mayo.
3. Stream in the Oil: Once the mixture has thickened and looks creamy (after about ¼ cup of oil has been incorporated), you can start adding the remaining oil in a very thin, steady stream while continuing to whisk. The mixture will become gloriously thick and pale.
4. Taste and Adjust: Once all the oil is incorporated, taste your masterpiece. You might want another pinch of salt or a tiny extra squeeze of lemon. Whisk it in.
5. Store and Use: Transfer to a clean jar, seal, and refrigerate. It’s now ready to become the star of your best homemade mayonnaise recipe for tuna salad.

Pro Tip: If your mayo breaks (looks thin and separated), don’t panic. Put a fresh egg yolk in a clean bowl and slowly whisk in the broken mixture, drop by drop, as if it were the new oil. It will almost always come back together.

Nutritional Information

Per tablespoon (approx.): 100 calories, 11g fat (1.5g saturated), 0g carbohydrates, 0g sugar, 0g protein. While rich, this mayo is free of the preservatives and added sugars found in many store brands. The egg yolk provides vitamins A, D, and E.

Equipment Needed

You don’t need fancy gear. A medium bowl and a sturdy wire whisk will do the job beautifully and build character (and maybe a little arm strength). For ultimate ease, an immersion blender or a small food processor makes the process nearly foolproof. A measuring spoon set and a liquid measuring cup for the oil are helpful.

Healthier Alternatives for the Recipe

• Lighter Option: Substitute up to half of the oil with a mild, plain Greek yogurt added at the very end. It lightens the texture and adds protein.
• Different Fats: Use a high-quality, light-tasting olive oil for a boost of monounsaturated fats.
• Egg-Free: For a vegan or egg-free version, use the brine from a can of chickpeas (aquafaba) as your emulsifier. Start with 2 tablespoons and whisk as directed.

Serving Suggestions

Of course, this mayo was born to be mixed with flaked albacore tuna, some diced celery and red onion, maybe a few capers. But its destiny doesn’t end there. Spread it on bread for the ultimate tuna melt, use it to bind a classic potato salad, or thin it with a little extra lemon juice for a drizzle over roasted vegetables. It’s also the perfect creamy base for my Lemon Dill Salmon Salad for a different seafood twist. For a fuller lunch plate, serve your tuna salad in a lettuce cup, on a bed of greens, or with a side of my tangy Dill Pickle Pasta Salad.

Common Mistakes to Avoid

1. Adding the Oil Too Fast: This is the number one reason for a broken mayo. Patience is not just a virtue here; it’s the law. Drop by drop at the start.
2. Using Cold Ingredients: Cold egg yolks and oil are harder to emulsify. Let everything sit on the counter for 20-30 minutes first.
3. Not Whisking Enough: A steady, vigorous whisk is your engine. If you stop or slow down during the initial oil addition, the emulsion can fail.
4. Over-seasoning Too Early: Season at the end. As the mayo thickens, flavors concentrate. You can always add more salt or acid, but you can’t take it out.
5. Using a Strong-Tasting Oil: Extra virgin olive oil can be bitter when emulsified raw. Stick with neutral oils for a classic best homemade mayonnaise recipe for tuna salad flavor.

Storing Tips for the Recipe

Store your homemade mayonnaise in a tightly sealed jar in the coldest part of your refrigerator. It will keep beautifully for up to 1 week. Because it contains a raw egg yolk, I do not recommend freezing it, as it can separate and become grainy upon thawing. Always use a clean spoon to scoop it out to prevent contamination. This makes it a perfect Sunday prep item for a week of great lunches, from tuna salad to adding a dollop to my BLT Pasta Salad.
