Craving something sweet? As crazy as it sounds, roasting onions makes them incredibly sweet, and sweet vegetables are a great way to fend off sugar and sweet cravings. Humble onions play a critical supporting role in the culinary world, giving wonderful flavor to many recipes. Instead of a supporting role, feature them as a side dish with these Balsamic roasted red onions. You will be amazed a their rich savory sweetness.
Balsamic Roasted Red Onions
Searching for more ways to add vegetables to your dinner table? Consider the onion. Inexpensive and readily available, red onions are available year round in the produce department. Plus, onions are a non-starchy vegetable, so you can eat lots of them (great for low carb diets). Recipes with red onions usually combine them with other vegetables, but not this one. Here, they shine on their own.
Red Onion Nutrition
Besides tasting good, are onions good for you? Yes. As part of the allium family, including garlic, leeks, chives and scallions, onions are rich in sulfur-containing compounds that give them both their pungent odor and much of their health benefits.
Onions are a good source of important vitamins, minerals, and health-protective plant nutrients called phytochemicals. "Research shows that eating onions may help reduce heart disease risk factors, such as high blood pressure, elevated triglyceride levels and inflammation".
Onions are also a good source of quercetin, a powerful antioxidant and natural antihistamine. Onions are generally a safe food if you have Histamine Intolerance. To be safe, pass on finishing your roasted onions with Balsamic unless you are well managed. They still taste terrific. Read more about the health benefits of onions here.
Oven Roasted Onions
But what to do with my one onion languishing in my pantry? Roast it. For me, the first answer always seems to be roasting. I cut up the onion and tossed it with olive oil, salt, pepper and my beloved granulated garlic that goes on everything. Into the oven went the onion, alongside a chicken roasting for dinner.

Roasting Makes for Sweetness
The edges of the onions had turned a deep brown, caramelized from the heat of the oven. Roasting turns a normally pungent, eye-watering, mascara-smearing onion into something as sweet as candy. Yes, I see you looking at me with doubt and skepticism. Trust me. You must make these.
Balsamic & Thyme For The Finish
As I pulled the casserole dish from the oven, the sweet smell wafted up to my nose. I knew these were going to taste great. I tossed the onions with a little good Balsamic and fresh chopped thyme.
You can use either regular Balsamic vinegar or take it one step further. Make Balsamic syrup. This handy little condiment is always in a squeeze bottle by my stove for such uses. For how to make Balsamic syrup, read this post.
Another terrific recipe with balsamic is these roasted balsamic glaze Brussels sprouts.
