Cutting the zucchini lengthwise into 1/4-inch-thick slices makes it easier to layer on top of the noodles. Slow-cooking the onion brings out its natural sweetness and provides a complementary flavor to sharp Gorgonzola cheese. Ingredients:
3 tablespoons butter, divided |
8 cups thinly sliced onion (about 2 pounds) |
1/2 teaspoon dried thyme |
1/4 teaspoon salt |
1/4 teaspoon black pepper |
1/2 cup dry white wine |
1 1/2 pounds zucchini, cut lengthwise into 1/4-inch-thick slices |
2 tablespoons all-purpose flour |
2 (12-ounce) cans evaporated fat-free milk |
1 1/4 cups (5 ounces) crumbled gorgonzola or other blue cheese |
1/8 teaspoon ground nutmeg |
cooking spray |
12 cooked lasagna noodles |
1/4 cup (1 ounce) grated fresh parmesan cheese |
Directions:
1. Preheat oven to 375°.
2. Melt 2 teaspoons butter in a large nonstick skillet over medium heat. Add onion, thyme, salt, and pepper; cook 20 minutes, stirring occasionally. Add the wine; cook 2 minutes or until wine evaporates. Spoon into a bowl; cool.
3. Melt 1 teaspoon butter in pan over medium-high heat. Add half of the zucchini; cook 2 minutes or until crisp-tender. Remove from pan. Add remaining zucchini; cook 2 minutes or until crisp-tender. Set aside.
4. Melt 2 tablespoons butter in a medium saucepan over medium heat. Add flour; cook 1 minute, stirring constantly with a whisk. Gradually add milk, stirring with a whisk. Cook 5 minutes or until thick, stirring constantly. Remove from heat. Add Gorgonzola and nutmeg; stir until cheese melts.
5. Spread 1/4 cup cheese sauce in the bottom of a 13 x 9-inch baking dish coated with cooking spray. Arrange 4 noodles slightly overlapping over cheese sauce; top with half of onion mixture, half of zucchini, and 1 cup cheese sauce. Repeat layers, ending with noodles. Spread the remaining cheese sauce over noodles. Sprinkle with Parmesan. Cover and bake at 375° for 30 minutes. Uncover and bake an additional 15 minutes. Let stand 5 minutes.
