Easy Roasted Cipollini Onions

Sharing is caring!

Need a good side dish? These easy roasted cipollini onions make the perfect fall side dish or Thanksgiving side dish.

I recently discovered the beauty of cipollini onions when I got a box of produce from Melissa's Produce. I had never heard of these onions before, but upon receiving them, did a little research and am so glad I was introduced.

Cipollini onions are much sweeter than regular onions and will caramelize so much better, making these easy roasted ones so delicious.

I am not going to lie — I sat there and ate almost this whole pan of onions. They were that good. They roast up quickly and when served with balsamic vinegar, it lends a nutty flavor to them as well.

How to Make Easy Roasted Cipollini Onions

For this, you will need a couple of boxes of cipollini onions.

Cut off each end of the onion and remove the skin. Then place them all in a cast-iron skillet with 4 tablespoons of butter. If you do not have a cast-iron skillet, you can use any that you want, as long as they are oven safe up to 400 degrees.

Turn the heat to medium and let the butter melt. Season with salt and pepper and let the onions begin to cook in the butter.

Saute the onions for about 3 minutes until one side is beginning to brown.

Then flip and let the other side brown.

Add in 3 tablespoons of balsamic vinegar and then place in a preheated 400-degree oven to finish caramelizing and cooking.

The balsamic will reduce and create a delicious sauce to spoon over the cipollini onions.

Continue cooking for about 15 minutes until the onions are caramelized and fork-tender.

What Can I Serve These Onions With?

These onions would be great served with my Mongolian Ground Beef Noodles recipe or my grilled steak alfredo. You can also serve these at Thanksgiving with Ina Garten's Perfectly Roasted Turkey.

I see them loose in my produce market not boxed so can you give me an approximate amount or weight you used?

I would say around 20 of them? I think that is what the approx amount was in the two boxes I had.
