Ingredients you’ll need:

- Fine Sea Salt

What type of onions work best for balsamic roasted onions?
Yellow onions are the most common choice because they caramelize well, but red onions add extra sweetness and color. Sweet onions also work beautifully.
How do I keep the onions from burning?
Roast at 400°F (205°C) and toss the onions halfway through cooking. If the balsamic starts to darken too quickly, loosely cover with foil for the final minutes.
Should I add balsamic vinegar before or after roasting?
Add it before roasting so it reduces and caramelizes in the oven. For extra shine and flavor, you can drizzle a little more after roasting.
Can I make balsamic roasted onions ahead of time?
Yes. Roast them up to 2 days ahead, store in the refrigerator, and reheat in the oven or on the stovetop before serving.
