Ingredients

  • For the Alfredo Sauce:
  • 8 ounces butter
  • 1 1/2 cups whipping cream
  • White pepper to taste (freshly ground)
  • 1 1/2 cups Parmesan cheese (fresh grated)
  • For the Ricotta Mixture:
  • 2 cups ricotta cheese
  • 1/3 cup Parmesan cheese (grated)
  • 3/4 cup mozzarella cheese (shredded)
  • 2 tablespoons green onions (sliced)
  • 2 teaspoons fresh parsley (chopped)
  • 1/2 teaspoon salt
  • 1/8 teaspoon black pepper
  • 1/4 teaspoon dried basil
  • 1/4 teaspoon dried oregano
  • 1 1/4 cups Alfredo sauce (prepared)
  • For the Vegetables:
  • 4 cups mushrooms (sliced)
  • 2 cups carrots (chopped)
  • 1 cup onion (chopped)
  • 1 tablespoon butter
  • 2 cups bell peppers (red, chopped or sliced)
  • 1 cup bell pepper (green, chopped or sliced)
  • 2 cups zucchini (sliced)
  • 4 cups broccoli (florets)
  • 12 to 15 lasagna noodles (see the first paragraph of the instructions)
  • 18 slices mozzarella

Steps to Make It

  1. Lay out enough dry lasagna noodles in a 9 x 13-inch baking pan to ensure you have enough to make 3 full layers, with very little overlap on each layer. Remove the dry strips and cook according to package instructions until just tender; drain.

  2. Alfredo Sauce - Heat water to a boil in the bottom of a double boiler. Add butter, cream, and pepper to the top pan and place over the simmering water until butter is completely melted; stir in Parmesan until melted and blended in. Turn off heat and remove top pan; set aside to cool. Measure 1 1/4 cups of the sauce; set aside. Put the remaining sauce in a container and keep refrigerated until close to serving time.

  3. Ricotta Filling - In a bowl, combine ricotta cheese, 1/3 cup Parmesan cheese, 3/4 cup shredded Mozzarella, 2 tablespoons green onions, 2 teaspoons of chopped parsley, 1/2 teaspoon salt, 1/8 teaspoon pepper, 1/4 teaspoon each basil and oregano, and 1 1/4 cups of cooled prepared Alfredo sauce. Blend well. Set aside.

  4. Heat the oven to  375 F.

  5. Vegetables - In a heavy skillet, saute mushrooms, carrots, and 1 cup of chopped onions in 1 tablespoon butter until just tender -- about 8 to 10 minutes. Add red and green bell pepper, zucchini, and broccoli; toss to mix well.

  6. Assembly - Grease bottom and sides of a 9x13x2-inch baking dish. Lay out 4 cooked lasagna strips to cover the entire bottom of the baking pan. Spread 1 1/4 cups of the Ricotta mixture evenly over the strips. Top with half of the vegetable mixture and spread out evenly. Cover the vegetable layer with 9 slices of Mozzarella cheese. Repeat this layering. Top the second layer of mozzarella slices with lasagna strips and spread them evenly with 1 1/4 cups ricotta cheese mixture to finish.

  7. Grease or spray a sheet of foil with vegetable spray and cover the baking dish tightly with the foil sprayed side down.

  8. Bake the lasagna for about an hour, or until the internal temp registers 165° on an instant-read thermometer. Remove from the oven and let stand for 5 minutes, covered, before cutting and serving.

  9. Heat reserved Alfredo sauce and spoon a little over each serving.
