There’s nothing I love more than an ultra-easy recipe that produces a truly memorable dish, and this recipe for Marinated and Roasted Vidalia Onion Rings with Parmesan is definitely one of those. I recently bought a big bag of Vidalia onions as part of a fundraiser, so I’ve been thinking of ways to use them. After I marinated some onions for the Greek Salad with Marinated Onions and Oregano, I had the idea of marinating and then roasting the onions. If you’re a fan of caramelized onions, this dish has that same umami-laden flavor. Next time you’re cooking something in the oven, try roasting some marinated sweet onions for a delicious side dish.

Vidalia onions come from Vidalia, Georgia, where the low sulfur soil produces sweet onions with a mild flavor. Only onions from Georgia can be called Vidalia onions, and the name is trademark-protected. Vidalia onions are my featured plant ingredient for Weekend Herb Blogging, hosted this week by Cinzia from Cindystar.

Vidalia onions are white with a slightly golden skin, and usually they’re sold when they’re just medium-sized. After peeling, I sliced the onions into slices about 1/2 inches thick Try to make all the onions slices the same thickness, and separate onions into rings after slicing.

Whisk together balsamic vinegar, olive oil, Spike Seasoning, and dried thyme, and marinate onions for 4 hours or longer. Let marinated onions drain well while you preheat the oven to 400 F. When oven is hot, arrange onions on a baking dish.

Roast onions for 30-40 minutes, turning every 10 minutes, or until onions are well-browned, especially on the edges. (I was cooking this in my toaster oven or I would have spread them out on the pan a bit more.) Serve hot, with a sprinkling of grated Parmesan.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Although onions are approved for every phase of the South Beach Diet, I’m guessing that sweet onions like I used in these Marinated and Roasted Vidalia Onion Rings with Parmesan are higher in sugar, and would probably be phase 2 or 3 for South Beach. For other low-carb diets you could eat a very small amount of this, but one Vidalia Onion has 16 carbs, so use portion control if you’re watching your carbs.
