Ingredients
- 2 pounds cipolline onions
- 2/3 cup balsamic vinegar
- 1 tablespoon plus 1/3 cup extra-virgin olive oil
- 1 teaspoon salt, plus more for seasoning
- 1/4 teaspoon freshly ground black pepper, plus more for seasoning
- 3 tablespoons fresh lemon juice
- 2 teaspoons chopped fresh thyme leaves
- 6 (6-ounce) tuna steaks (about 1-inch thick)
Directions
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. Roast in the oven until the onions are tender and golden, stirring occasionally, about 1 hour.
Meanwhile, whisk the 1/3 cup oil, lemon juice, thyme, and remaining 1/2 teaspoon of salt and 1/4 teaspoon of pepper in another 13 by 9 by 2-inch baking dish. Place the tuna steaks in the marinade and turn to coat. Let stand for 5 minutes on each side.
Oil the grill rack and prepare the barbecue for medium-high heat. Grill the steaks to desired doneness, about 3 minutes per side for medium. Cut the steaks in half. Transfer the steaks to a platter. Spoon the onion mixture around and serve.

Loved these onions! The sauce was just wonderful. Mine didn't burn, but I check my food often while cooking because cooking times in recipies are always estimates because everyone's ovens are different. Mine were done in about 45 minutes so I took them out. I used a small ceramic baker lined with foil. Oh, and as someone else said, heat rises and collects at the top of your over. I've found that items cooked on the top rack will dry out and burn faster. But again, ovens vary. I cooked these on the lower rack with great results

I don't eat onions, but my husband does so I decided to try it, what a great idea I tell you! The Cipolline onions are Delicious! yes, this is coming from a non onion eater! You have to try them!
On the other hand I didn't have tuna so I made chicken breasts instead and also didn't have much herbs so used cilantro for the marinade, it was delicious!!!! may try the real recipe in the future, but hubby was super happy with me and the meal this time :
Definitely a have to, specially since it is sooo easy and simple to make :
