Like all my sauce recipes, this sweet onion sauce requires simple ingredients you might already have in your kitchen.

Labelled ingredients for sweet onion vinaigrette.
  • Fresh Onion: You don’t need any specific kind like Vidalia onions. Any type (white, yellow or red onions) work for this recipe. 
  • Olive oil: Use either regular one or extra virgin olive oil for a stronger fruity flavor.
  • Chia seeds: This is the SECRET INGREDIENT that emulsifies the dressing. They help reduce the oil (and hence calorie) content of the recipe. The health benefits of chia seeds are a plus for this salad dressing.
  • Lemon juice
  • A touch of honey and brown sugar: We caramelize the onion that unlocks its natural sweetness. (Secret trick!) That helps us reduce the quantity of added sugar in the recipe.​
  • Dijon mustard: Adds a bit of spice and zesty flavor.
  • Black pepper and salt

Instructions
 

Soak chia seeds

  • Add water to chia seeds in a small bowl. Stir after a minute so that they don't clump together. Allow them to soak for 10 to 15 minutes.

Sauté the onion

  • Thinly slice the onion.
  • Heat oil in a large pan. Add onion slices and salt. 
  • Sauté on low heat for 10 minutes.
  • Add brown sugar. Sauté for 10 more minutes.
  • Let the onion cool down.

Blend

  • Place the caramelized onion slices, soaked chia seeds, lemon juice, honey, Dijon mustard, black pepper and water in a food processor. 
  • Blend until you get a smooth sauce.
  • Drizzle this delicious dressing on your favorite salad or use it as a dipping sauce.

Notes

    • Added sugar: Caramelizing the onion makes it sweet. So you’ll need only a teaspoon of brown sugar and a tablespoon of honey to make this dressing. You can add more, if you want a sweeter sauce.
    • Caramelizing the onion: Sauté the onion slices on low flame for a good 15 to 20 minutes, or even longer. The more you caramelize the onion, the sweeter the dressing turns out. Keep an eye on it to ensure it doesn’t burn. Golden brown is what you should aim at.
    • Vinegar: Lemon juice provides a perfect balance to the sweetness of the dressing. If you want more of a tangy flavor, add a teaspoon of apple cider vinegar or white wine vinegar.
    • Vegan option: Honey can be replaced with maple syrup.
    • Making it for a crowd: This recipe can be easily scaled up or down. Use the slider that will appear if you hover your mouse over the number of servings above.
    • Storing: This dressing keeps well since you don’t use raw onions here. It stays fresh in the refrigerator for about 5 days.
    • Freezing: You can store it in the freezer for about a month.
