The Ultimate 3-Ingredient Salad Dressing Recipe (So Easy, Even a 5-Year-Old Can Make It!)

As the sun shines brightly and the days grow longer, there's nothing quite like a fresh salad to celebrate the season. But what elevates a simple salad to a culinary delight? The answer lies in the dressing! Store-bought options often fall flat, lacking the vibrant flavors and freshness that homemade dressings can offer. If you think making your own dressing is complicated, think again! Food writer Myo Quinn has been using the same simple salad dressing for over 20 years, and even her 5-year-old can whip it up effortlessly. This dressing is flavorful, versatile, and comes together in just minutes using only three key ingredients: Dijon mustard, lemon juice, and olive oil.

Why Make Your Own Salad Dressing?

Myo passionately believes that homemade salad dressings win over store-bought ones every time. Here’s why:

  • Better Taste – Fresh ingredients enhance flavors.
  • More Affordable – No need to keep buying expensive bottled dressings.
  • Super Quick – Ready in under five minutes!

Plus, this dressing is so easy that even her young kids make it regularly—just a small bowl, a fork, and a few staple ingredients are all you need.

The Three Ingredients (And Why They Work)

1. Dijon Mustard – The Secret to Creamy Dressings

Many people underestimate Dijon mustard in salad dressings, but it plays a crucial role as an emulsifier. This simply means it helps oil and acid mix together, preventing the dreaded separation. The result? A smooth, creamy dressing. (Don't swap it for yellow mustard… keep that for your hot dogs!)

2. Lemon Juice – The Tangy Brightener

Fresh lemon juice provides vibrant acidity that balances the richness of the olive oil. No lemons? Swap in red wine vinegar, apple cider vinegar, or white wine vinegar.

3. Olive Oil – The Smooth Blender

Olive oil adds richness while rounding out flavors. Depending on your preference, adjust the amount you use to control the dressing’s consistency.

The Easiest Salad Dressing Recipe

Ingredients

  1. ½ small lemon, juiced (about 2 tablespoons)
  2. 2 teaspoons Dijon mustard
  3. ¼ to ⅓ cup olive oil
  4. 1 clove garlic (optional but highly recommended)
  5. Salt and black pepper, to taste

Instructions

  1. In a small bowl, whisk together lemon juice and Dijon mustard using a fork.
  2. Slowly drizzle in olive oil, whisking constantly until the dressing becomes golden and creamy.
  3. Season with salt and black pepper—start with ¼ teaspoon salt and ⅛ teaspoon black pepper, then adjust to taste.
  4. (Optional) Add garlic: Lightly crush a garlic clove, peel it, and drop it into the dressing. Let it sit to infuse flavors, then remove before serving. (Pro tip: Save the garlic for cooking later!)
