This Lemon Dijon Dressing is bright, balanced, and ready in just 5 minutes. It's my go-to vinaigrette for grain bowls, grilled chicken, and green salads because it's easy to make yet tastes restaurant-quality with simple ingredients. Lemon Dijon Dressing is a classic vinaigrette made with fresh lemon juice, Dijon mustard, olive oil, and salt. The mustard acts as a natural emulsifier, helping the dressing stay well blended.
