Homemade Mayo Recipe Immersion Blender: Foolproof Emulsion in 60 Seconds

This immersion blender method delivers foolproof homemade mayo every time. No whisking, no splitting—just a 60-second process that creates silky, restaurant-quality results with basic ingredients.

The secret lies in the slow drizzle and steady blending, which builds a stable emulsion without fail. You’ll achieve creamy, rich mayo that puts store-bought versions to shame.

The oil quality is paramount here. Avocado oil or light olive oil are ideal for their neutral flavor and high smoke point. Costco’s Kirkland or California Olive Ranch offer reliable options at reasonable prices. Always start with room temperature ingredients—the cold can break your emulsion. The egg yolk should be fresh, and while pasteurized works, conventional yields better texture.

No white wine vinegar? Apple cider vinegar or rice vinegar are suitable substitutes. Out of Dijon? Yellow mustard at the same amount will work in a pinch. For a tangier result, increase lemon juice to 1.5 tbsp. The sugar is optional but recommended—it softens the sharpness without sweetening. If avoiding sugar, a pinch of baking soda neutralizes acidity effectively.

This keeps in an airtight container in the refrigerator for 1 week. The flavor actually improves after 24 hours as it rests. For longer storage, freeze in ice cube trays for up to 3 months. Thaw in the fridge before using.

Step-by-Step Instructions for Homemade Mayo

Master the immersion blender technique for a perfect emulsion every time you make this.

Step 1: Combine the Base Ingredients

Place the large egg yolk, 1 tsp Dijon mustard, 1 tbsp white wine vinegar, 0.5 tsp salt, 1 tbsp lemon juice, and 0.25 tsp granulated sugar in a tall, narrow container that fits your immersion blender. The mustard acts as a natural emulsifier, while the vinegar and lemon juice provide the necessary acidity for balance.

I use a pint-sized mason jar for this—it’s the perfect width for the blender head and allows the ingredients to stay concentrated at the bottom. Ensure all ingredients are at room temperature, especially the egg yolk, as cold ingredients can prevent proper emulsification.

Step 2: Begin the Emulsion with the Oil

Add 1 cup neutral oil to the container, pouring it directly on top of the other ingredients. The oil should completely cover the liquid mixture. Insert the immersion blender all the way to the bottom of the container, ensuring the blades are fully submerged in the liquid layer beneath the oil.

Start blending on high speed without moving the blender. You’ll see the mixture at the bottom begin to thicken and turn pale yellow within 10-15 seconds. This is the emulsion forming—a critical moment where the oil and liquids bind together permanently.

Step 3: Gradually Incorporate the Remaining Oil

Once the emulsion begins to form at the bottom, start moving the immersion blender very slowly upward, keeping the blades just below the surface of the thickening mixture. As you blend, the emulsion will naturally pull more oil down from the top, incorporating it into the mayonnaise.

Continue this slow, steady movement until all the oil is fully emulsified. The process should take no more than 30-45 seconds total. You’ll know it’s ready when the mixture is thick, creamy, and consistent throughout, with no separated oil visible on the surface.

Step 4: Adjust and Finish

Turn off the blender and check the consistency. If it appears too thick, you can thin it slightly with a teaspoon of water and blend again briefly. Taste and adjust the seasoning if needed—though the initial measurements should yield a perfectly balanced flavor.

The finished product should have a glossy appearance and hold its shape when a spoon is dipped in. Transfer to a clean jar and store in the refrigerator for up to 1 week. The mayonnaise will thicken slightly as it chills, reaching its ideal texture after 1 hour in the fridge.

Essential Equipment for This Dish

Must-Have Tools

To make the perfect homemade mayo with an immersion blender, you’ll need a few key items. First up is, of course, a reliable immersion blender—brands like Cuisinart or Braun work wonders for creating a smooth, creamy emulsion in seconds. A tall, narrow container (like a mason jar or a deep cup) is also essential to help the blender fully incorporate the oil into the egg yolk without splattering.

Don’t forget a measuring cup with a spout for slow, steady oil drizzling—this is crucial for a stable emulsion. A whisk can be handy for initial mixing, but the immersion blender will do most of the heavy lifting. 🥘

Nice-to-Have Tools

For extra convenience, consider a digital kitchen scale to measure ingredients precisely, or a squeeze bottle for easy mayo dispensing. A fine-mesh strainer can help sift in dry ingredients like mustard powder for a lump-free texture.

If you plan to make mayo often, a wide-mouth pint jar with measurements etched on the side can streamline the process. These aren’t deal-breakers, but they’ll make your life easier! ✨

Budget Alternatives

No immersion blender? No problem! A whisk and a bowl will work, though it’ll require more elbow grease and patience. Use a bowl with a non-slip base or place it on a damp towel to keep it steady while you whisk.

For oil drizzling, a plastic bottle with a small hole punctured in the cap can mimic a slow pour. And if you don’t have a tall container, any deep, narrow vessel (even a clean, empty wine bottle) can serve as a makeshift blending jar. 💡
