In a small jar with a screwtop lid, combine olive oil, vinegar, sugar, onion, thyme, salt, and pepper. Shake vigorously until emulsified. Let sit for 1 hour for flavors to meld. Shake again before using.
Notes
Apple Cider Vinaigrette can be made and refrigerated up to a day in advance. Let come to room temperature before using. Shake well to emulsify.
