Bring a large pot of water to boil. Add the onions and cook for 2 minutes. Drain and cool. Peel the onions and cut off the root ends.Preheat the oven to 450 degrees F. Toss the onions, vinegar, 1 tablespoon oil, 1/2 teaspoon of salt and 1/4 teaspoon of pepper in a 13 by 9-inch baking dish.

Should be 10 star recipe
Rated: 5 stars out of 5

Thank you Giada for this fantastic recipe. I did not and could not find the cipolline onions so I used red onions. Having... read the reiviews I really kept and eye on the onions while they were roasting. At 45 minutes they seemed pretty done so I turned off the oven and let them sit for another 15 minutes. I also sprayed my baking dish with olive oil and this made clean up very easy. I will make this again and again and probably use the onions for steaks and even pork chops. Thanks Giada for helping me to be a good cook in all the years I have followed you and made your recipes I've only had 1 failure and everything else is always fantastic. Bonnie BarneyRead more

Sauce is delicious!
Rated: 4 stars out of 5

Ok, I screwed this recipe up royally, but it has so much potential! First I used challots cause there was nothing resembling... the cipolline onions at my local market. I wouldn't say don't do that necessarily, but I was desperate trying to practice for a nice Good Friday meal. ANYWAY, the point is, although the onions were not great, the sauce is AMAZING! WOW, it adds so much flavor to the tuna. And I agree with the comment below about the marinade, can't really taste it, but the sauce is so good it really does not matter. Personally, I liked the sweetness of the sauce so much, I'm gonna try it without the onions to see how it turns out. Definitely a recipe worth keeping though.Read more

A few substitutions but so yummy
Rated: 4 stars out of 5

I used tilapia instead of tuna, just for personal taste. The marinade worked really well for it. I loved the onions but an... hour was a little too long and the balsamic dried to the bottom of the baking dish. Would like to redo and only cook the onions for about 40 min. Very easy and very tasty.Read more

Forget the Tuna - the Onions Rock with Steak!
Rated: 5 stars out of 5

I saved this recipe for the onions and made them tonight with Porterhouse Steaks on the Grill and Oven Roasted Asparagus... w/EVOO, S+P and Roasted Garlic Marscapone Carmelized Onion Mashed Potatoes. The Balsamic turned syrupy and made the onions sugary sweet - Yum-o (Sorry Rach)Read more

Delicious, tasty, and easy!
Rated: 5 stars out of 5

What more can I say but.... yummy! The tuna was absolutely delicious and easy along with the cippolini onions. I had... recorded the episode on my DVR and watched it before I made the entire recipe. For the onions, I used 1/3 cup balsamic vinegar and half of that amount for the olive oil. Just remember to put your oven rack at the LOWEST point in the oven. NOT on the top shelf as some here have said otherwise they will burn. The balsamic reduction was wonderful. I thought my husband was going to lick his plate. The polenta was also a hearty and delicious side dish. I couldn't find the quick cooking type so it took me an additional half hour but it still turned out perfect. This recipe is a keeper. Thanks Giada!!!Read more

Listen more carefully
Rated: 5 stars out of 5

Just an FYI to those who want to make this dish - do not listen to the people who complained that they listened to Giada and... followed her hint of putting the roasting pan closer to the top of the oven...what she says is to put in in the LOWER part of the oven so they WON'T burn. The dish is very good.Read more
