Pancetta is Italian cured pork, similar to cured bacon, which you can substitute, if necessary. Smoked bacon will also work, if you prefer the flavor. Ingredients:
2 tablespoons butter |
1 ounce pancetta, chopped |
1/4 cup chopped shallots |
2 garlic cloves, minced |
1.38 ounces all-purpose flour, divided (about 5 tablespoons) |
1 teaspoon chopped fresh thyme |
2 cups 2% reduced-fat milk |
3/4 cup (3 ounces) grated fresh parmigiano-reggiano cheese |
1/2 teaspoon salt |
1/2 teaspoon freshly ground black pepper |
1/8 teaspoon ground red pepper |
1 pound baking potato, peeled and cut into 1/8-inch-thick slices |
8 ounces sweet potato, peeled and cut into 1/8-inch-thick slices |
8 ounces butternut squash, peeled and cut into 1/8-inch-thick slices |
cooking spray |
1/3 cup (1 1/2 ounces) shredded gruyère cheese |
Directions:
1. Preheat oven to 375°.
2. Melt butter in a small saucepan over medium-high heat. Add pancetta; cook 1 minute. Add shallots and garlic; cook 2 minutes, stirring constantly. Weigh or lightly spoon 1.1 ounces (about 1/4 cup) flour into a dry measuring cup; level with a knife. Add to pan; cook 2 minutes, stirring constantly with a whisk. Stir in thyme. Gradually add milk, stirring constantly with a whisk; cook over medium heat until slightly thick (about 3 minutes), stirring constantly. Stir in Parmigiano-Reggiano; cook 3 minutes or until cheese melts. Stir in salt and peppers. Remove from heat.
3. Cook baking potato in boiling water 4 minutes or until almost tender; remove with a slotted spoon. Cook sweet potato in boiling water 4 minutes or until almost tender; remove with a slotted spoon. Cook butternut squash in boiling water 4 minutes or until almost tender; drain. Sprinkle vegetables evenly with remaining 1 tablespoon flour. Arrange potatoes and squash in alternating layers in a broiler-safe 11 x 7-inch baking dish coated with cooking spray; spoon sauce over potato mixture. Top with Gruyère. Bake at 375° for 40 minutes.
4. Preheat broiler. Broil 3 minutes or until golden. Let stand 10 minutes.
