Rick Tramonto - Osteria Cookbook
Talk about succulent! The yellow onions are pretty pungent when you slice them, but surrender their kick when they are roasted and become sweet and tender. When they reach this point, the cream sauce is poured over them, they are topped with shaved cheese, and then the whole thing is returned to the oven for a slow melt. I like to cook these in a wood oven to get some smoke on them, which makes them even better-if that's possible. Great with chicken, lamb, beef-you name it! I also like it served as a first course.
4 medium yellow onions
1/4 cup extra virgin olive oil
Kosher salt and freshly ground black pepper
1 cup heavy cream
1/4 cup dry white wine
Minced Garlic (my addition)
2 ounces Parmigiano-Reggiano cheese, shaved (about 2 tablespoons)
1 Preheat the oven to 350°F.
2 slices the onions into 1/4-inch-thick rings and lay them in a shallow baking pan, such as a sheet pan or jelly roll pan. Drizzle with the olive oil and season to taste with salt and pepper. Roast for 15 to 18 minutes, or until lightly browned.
3 Meanwhile, in a medium saucepan, bring the cream and wine (and Garlic)to a simmer over medium-high heat. As soon as the liquid starts to bubble around the edges, remove from the heat.
4 Spoon about a tablespoon of the cream mixture over each onion slice. Cover with aluminum foil, return to the oven, and cook for about 25 minutes. Increase the oven temperature to 450°F.
5 Remove the foil and top the onions with the shaved cheese. Return the pan to the oven and cook for 4 to 5 minutes, or until the edges caramelize. Serve hot.
