Sweet Vidalia onions and rich, caramel-like balsamic vinegar combine to make a delightfully sweet, complex dish that you and your guests won't be bale to get enough of. There's nothing like baked onions as the perfect side to complement any entrée. The balsamic vinegar sauce is also flavored with olive oil, sugar, fresh thyme, and a little salt and pepper. You should already have a majority of these ingredients on hand, making this a great no-fuss recipe to help put your dinner menu over the top. Most of the bake time is hands off, but you need to keep an eye on the onions and baste them occasionally so they don't burn.


Vidalia onion

16 oz, 2 (8-ounce) peeled, trimmed, and sliced 1⁄4-inch thick


¼ cup(s)

Olive oil

2 tsp

Balsamic vinegar

2 Tbsp


2 tsp

Fresh thyme

½ Tbsp, fresh, chopped

Table salt

¼ tsp

Black pepper

tsp, freshly ground, or to taste


  1. Preheat the oven to 425ºF. Spread the onions evenly in a 9 x 13-inch baking dish; pour in the water. Drizzle with the oil and vinegar; sprinkle with the sugar, thyme, salt, and pepper. Cover and bake until tender, about 30 minutes.
  2. Uncover and continue baking, adding water 1⁄4 cup at a time as needed to keep the onions moist, basting occasionally, until the onions are golden brown and caramelized, about 25 minutes. Garnish with the fresh thyme sprigs, if using. Yields 1/2 onion per serving.
