This homemade Caesar dressing delivers classic flavor with an easier, no-fuss technique using immersion-blender mayo, real Parmesan, and bright lemon. It’s rich, tangy, customizable, and perfect for salads, wraps, veggies, or dipping everything in sight.
In a tall container, add 1 whole egg, 1 tablespoon lemon juice or white vinegar, 1 teaspoon Dijon mustard, and ¼ teaspoon salt in that order. The egg needs to be at the bottom.
Add 1 cup avocado oil on top.
Place your immersion blender all the way to the bottom of the cup.
Turn the blender on and hold it at the bottom of the cup. Do not move for about 20 seconds.
When the mixture goes from oil to a thick white color, slowly lift the immersion blender up and down to incorporate all of the oil into the egg.
When the entire container is consistently mixed, turn off the blender.
Caesar Dressing
Zest the lemon and grate the garlic into a mixing bowl.
Add 1 tablespoon lemon juice, 1 teaspoon lemon zest, 2 teaspoons Dijon mustard, ½ teaspoon garlic, 1 teaspoon Worcestershire, 1 teaspoon garlic powder, ½ teaspoon anchovy paste, ¼ teaspoon black pepper, and ¼ teaspoon salt . Mix until smooth.
Stir in 1 cup mayonnaise.
Add ¼ cup buttermilk a splash at a time until you reach your ideal consistency—spoonable or pourable.
Fold in ⅓ cup Parmesan cheese.
Refrigerate for at least 1 hour so the flavors mellow, deepen, and marry.
Taste and adjust: more lemon for brightness, more anchovy for salt and umami, more pepper if you like a sharper edge.
Notes
Always use a microplane. Lemon zest, garlic, and Parmesan melt seamlessly into the dressing instead of clumping.Balance the dressing:
Too tart → add a bit more anchovy paste or Worcestershire
Too bland → add lemon juice or a pinch of salt
Too thick → add more buttermilk
Too thin → stir in extra mayo or Parmesan
Let it rest. Caesar dressing tastes its best after an hour in the fridge.Storage: Store in an airtight container in the refrigerator for up to 3 days.
