By blum099

Ingredients

• 2 medium yellow onions, cored and quartered lengthwise
• 1/4 cup olive oil Kosher salt and freshly ground black pepper, to taste
• 2 tbsp. unsalted butter
• 2 tbsp. flour
• 1 cup heavy cream
• 1/4 cup dry white wine Freshly grated nutmeg, to taste
• 1/2 cup finely grated parmesan
• 3 oz. Gorgonzola, crumbled
• 1/4 tsp. paprika

Preparation

Step 1

Heat oven to 350°. Toss onions with oil in a 9″ × 11″ baking dish and season with salt and pepper. Bake, stirring occasionally, until soft and lightly browned, about 1 hour; set aside. Heat oven to broil.

Heat butter in a 2-qt. saucepan over medium-high heat; add flour, and cook, stirring, until smooth, about 1 minute. Add cream and wine, and cook, stirring, until thickened, about 5 minutes. Season sauce with salt, pepper, and nutmeg.

Pour sauce evenly over onions. Sprinkle with parmesan, dot with Gorgonzola, and sprinkle with paprika; broil until cheese is melted and golden brown on top, about 2 minutes.
