Sheet Pan Vegetable Lasagna

My version of Giada De Laurentiis sheet pan lasagna is made with a simple homemade bechamel sauce, store bought pesto, and frozen vegetables rather than a tomato meat sauce.  It’s rich, satisfying and packed with veggies!

  1. Preheat oven to 400F

  7. Bring a large pot of salted water to boil. Add lasagna noodles and cook until al dente. Drain the pasta of all the water, add the pasta back to the post and immediately mix in the pesto sauce.
  8. Lightly grease  a 12 x 17 pan with 1 tbsp olive oil. Add 1/2 the bechamel sauce to the greased pan and use a spatula to evenly spread the sauce to cover the pan.
  9. Next evenly distribute the pesto lasagna noodles, followed by the all of the veggies.
  10. Add dollops of the the remaining bechamel sauce and use the spatula to spread it over the veggies.
  11. Top with remaining 1/2 cup grated parm, all the shredded mozzarella and dollops of the ricotta mixture.
