Best Onions Agrodolce Recipes

BEEF TENDERLOIN WITH CIPOLLINI ONIONS AGRODOLCE

Steps:

• Place onions, butter, sugar, 1/2 teaspoon salt, 1/4 teaspoon pepper in single layer in a large straight-sided saute pan; add 1 inch of water. Simmer over medium heat, covered, 1 hour; the onions should be soft. Uncover; add vinegar. Cook, turning occasionally, until liquid evaporates and onions caramelize, about 1 hour. Stir in thyme leaves. Set aside.
• Heat oven to 400 degrees. Coat meat with remaining salt and pepper. Place saute pan with ovenproof handle over high heat. Add olive oil; heat until almost smoking. Place beef in pan; sear until well browned on all sides. Transfer to oven; roast 30 to 40 minutes, or until internal temperature is 130 degrees for medium rare. Allow to rest at least 10 minutes before slicing. Beef may be served warm or at room temperature. Slice just before serving. Place on platter with reserved cipollini onions; garnish with thyme sprigs.

GLAZED ONIONS AGRODOLCE

Steps:

• Preheat the oven to 400 degrees F. Cover the bottom of a medium, heavy-bottomed baking dish with the olive oil, balsamic vinegar, sugar, and fennel fronds. Season with salt.
• Cut the onions in quarters lengthwise. Trim the root ends of the onions, still leaving them intact. Lay the onions cut side down in the baking dish in concentric circles, fitting them closely together. Nestle a fresh bay leaf between every few onion halves and top with the sage. Drizzle with a bit more olive oil and a few drops of balsamic vinegar. Season with salt.
• Cover the pan with heavy-duty, restaurant-grade plastic wrap, which won't melt in the oven, and then aluminum foil. (Conventional plastic wrap will melt in the oven, so if you do not have restaurant-grade plastic wrap, skip it.) Put the onions in the oven until they're softened, about 40 minutes.
• To check for doneness, remove the baking dish from the oven and carefully lift up one segment of the foil and plastic if you're using it, taking care not to burn yourself from the steam that arises from the pan; use a small sharp knife to check to see if the onions are tender. Otherwise, return the foil and plastic and return the onions to the oven for another 10 to 15 minutes, or until they're tender.
