This quick 3-ingredient mayonnaise uses an immersion blender to create a thick, silky emulsion in under 2 minutes. It’s clean, customizable, and fresher than store-bought.
Use a tall, narrow container for fastest emulsification. Neutral oils like avocado, grapeseed, sunflower, or light olive oil work best; avoid robust extra-virgin olive oil. A room-temperature egg blends slightly faster. If the mayo seems thin, blend longer or add 1–2 teaspoons more oil. Store in a clean, airtight jar in the refrigerator and use within 5–7 days. For variations, add garlic, chipotle, fresh herbs, sriracha, honey-mustard, lemon zest with pepper, or roasted garlic.
