Ingredients
  

Main Ingredients
  • 1/2 cup Sweet Onion e.g., Vidalia, finely chopped
  • 2 tbsp Dijon Mustard
  • 1/4 cup Apple Cider Vinegar
  • 1/2 cup Extra Virgin Olive Oil
  • 1 tbsp Maple Syrup or honey
  • 1 clove Garlic minced
  • 1/2 tsp Salt
  • 1/4 tsp Black Pepper freshly ground
  • 1-2 tbsp Water optional, for thinning

Equipment

  • Blender or Food Processor
  • Measuring Cups
  • Measuring Spoons
  • Cutting board
  • Sharp knife
  • Airtight jar or bottle

Method
 

Preparation
  1. Finely chop the sweet onion and mince the garlic.
Blending the Vinaigrette
  1. In a blender or food processor, combine the chopped sweet onion, Dijon mustard, apple cider vinegar, maple syrup, minced garlic, salt, and freshly ground black pepper.
  2. Blend on high until the mixture is smooth and the onion is completely pulverized. Scrape down the sides if necessary to ensure everything is well combined.
  3. With the blender or food processor running on low, slowly drizzle in the extra virgin olive oil until the sweet onion dijon vinaigrette is fully emulsified and slightly thickened.
Final Adjustments and Storage
  1. Taste the vinaigrette and adjust salt, pepper, or sweetness if needed. If it's too thick, add 1-2 tablespoons of cold water, a teaspoon at a time, until the desired consistency is reached.
  2. Transfer the sweet onion dijon vinaigrette to an airtight jar or bottle. Store in the refrigerator.

Notes

Store your sweet onion dijon vinaigrette in the refrigerator for up to 1 week. Always shake well before each use, as some separation may occur naturally. This versatile dressing is excellent on green salads, as a marinade for chicken, or drizzled over roasted vegetables. For an extra kick, a pinch of red pepper flakes can be added to the blender.
