Start by measuring out all your ingredients. Having everything ready to go will make the process smoother.
In a mixing bowl, combine the diced onion, honey, soy sauce, sugar, minced garlic, and crushed red pepper if you’re using it. Stir well to combine.
Pour in the balsamic vinegar and mix until the ingredients are fully incorporated.
Slowly drizzle in the olive oil while whisking continuously. This will help emulsify the dressing, giving it a creamy texture.
Taste your dressing and adjust the flavors as needed. You can add more honey for sweetness or a splash more vinegar for tang.
If you’re not using it immediately, pour the vinaigrette into a jar with a lid and store it in the refrigerator. Give it a good shake before serving.
