Ingredients
2 heads Chioggia or Treviso radicchio halved lengthwise, or Verona radicchio cut into 2-inch-wide wedges
2 tablespoons unsalted butter, plus butter to coat baking dish
2 tablespoons flour
1 ½ cups milk
1 teaspoon kosher salt, or to taste
Freshly ground black pepper to taste
4 tablespoons freshly grated Parmesan cheese
8 very thin slices of prosciutto
Preparation
- Step 1
If using Chioggia or Treviso radicchio, trim stalks to ½ inch.
- Step 2
Fill a large, deep saute pan with salted water. Bring to a boil and immediately lower to a simmer. Place radicchio in water in a single layer. Cover with a clean tea towel. Cook in barely simmering water for 30 minutes.
- Step 3
While radicchio is simmering, prepare a bechamel sauce. In a medium saucepan, melt 2 tablespoons butter. Stir in the flour. Cook over low heat 3 minutes, stirring constantly. Slowly whisk in the milk. Whisk over medium heat until boiling and cook 3 minutes longer. Stir in kosher salt and pepper. Remove from heat and stir in Parmesan cheese.
- Step 4
Preheat oven to 350 degrees. Butter an 8-inch square oven dish.
- Step 5
Drain radicchio. (Liquid may be saved for another use.) Wrap each section in a slice of prosciutto. Arrange in a single layer in buttered pan. Pour bechamel on top, smoothing sauce into corners of pan. Bake for 15 to 18 minutes or until bubbly.
