Chicken, Mushroom, and Spinach Lasagna

Ingredients:

  • 2 1/2 Tbsp. olive oil
  • 1 cup chopped onion
  • 2 Tbsp. minced garlic
  • 8 oz. white mushrooms, thinly sliced
  • 1 tsp. dried basil
  • 1 tsp. dried oregano
  • 1/2 tsp. red pepper flakes
  • 1 1/4 tsp. kosher salt, divided
  • 1 (6 oz.) bag fresh baby spinach
  • 2 cups shredded cooked chicken
  • 2 cups low-sodium chicken stock
  • 1/4 cup all-purpose flour
  • 2 cups whole milk
  • 1/4 tsp. nutmeg
  • 1/2 cup shredded Parmesan cheese
  • 8 no-boil (oven-ready) lasagna noodles
  • 1 1/4 cups shredded mozzarella cheese

Directions:

  1. Preheat the oven to 375 degrees F.
  2. Heat a large sauté pan over medium-high heat. When hot, add oil and then the onions, garlic, mushrooms, basil, oregano, red pepper flakes, and 1/4 teaspoon of salt. Sauté for 5 minutes or until the mushrooms soften while stirring occasionally.
  3. Stir in spinach; cook until wilted and all of its moisture has evaporated. Remove the pan from the heat and stir in the cooked chicken. Set it aside.
  4. In a small bowl make a slurry by whisking together 1/2 cup chicken stock with flour. It should be thick milky consistency. Set it aside. In a small saucepan, combine the remaining 1 1/2 cups chicken broth, milk, nutmeg, and 1 teaspoon of salt. Bring to a slow simmer over medium heat, stirring occassionally. Once the mixture starts to bubble up around the edges, add the slurry while whisking nonstop. Simmer until thickened, about 5-8 minute, whisking occassionally. Stir in Parmesan cheese and then remove from heat.
  5. Pour 1/2 cup sauce into bottom of 10X10 square baking dish, top with 2 noodles, 1 cup chicken mixture, 1 cup sauce, and 1/4 cup mozzarella, making sure noodles are covered with sauce. You can even press them down lightly. Repeat 3 more layers with noodles, chicken, sauce, and cheese. Last layer will have slightly more sauce and remaining cheese on top.
  6. Cover baking dish with aluminum foil and bake for 25 minutes. Uncover and bake for 15 minutes longer. If desired, broil for 2-3 minutes for golden brown top. Let stand 15-20 minutes before cutting and serving.
