Chicken, Mushroom, and Spinach Lasagna

Lasagna night just got a whole lot cozier with this Chicken, Mushroom, and Spinach Lasagna! Packed with creamy layers of tender chicken, earthy mushrooms, fresh spinach, and a luscious white sauce, this dish is comfort food at its finest.

Ingredients

Scale

For the Lasagna:

  • 3 cups cooked chicken, shredded (rotisserie chicken works great!)
  • 12 lasagna noodles, cooked and drained
  • 2 cups fresh spinach, chopped
  • 2 cups mushrooms, sliced
  • 3 cups ricotta cheese
  • 1 1/2 cups shredded mozzarella cheese
  • 1 cup grated Parmesan cheese
  • 1 teaspoon Italian seasoning
  • Salt and pepper to taste

For the White Sauce (Bechamel Sauce):

  • 4 tablespoons butter
  • 1/4 cup all-purpose flour
  • 3 cups whole milk
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon ground nutmeg
  • Salt and pepper to taste

Instructions

Step 1: Preheat and Prep

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish to prevent sticking.

Step 2: Prepare the White Sauce

  • In a medium saucepan, melt the butter over medium heat.
  • Add the flour and whisk continuously for about 1 minute to form a smooth paste.
  • Gradually add the milk, whisking constantly to avoid lumps. Continue to cook until the sauce thickens, about 5-7 minutes.
  • Once thickened, add garlic powder, nutmeg, salt, and pepper. Stir well and remove from heat.

Tip: If you prefer a richer sauce, you can substitute some of the milk with heavy cream.

Step 3: Cook the Mushrooms and Spinach

  • In a large skillet, sauté the mushrooms in a little butter over medium heat for 5-7 minutes until softened.
  • Add the spinach and cook for an additional 2 minutes, or until wilted. Season with salt and pepper.

Step 4: Mix the Filling

In a large bowl, combine the shredded chicken, ricotta cheese, mozzarella, Parmesan, Italian seasoning, and the cooked mushroom-spinach mixture. Stir until everything is well combined.

Step 5: Assemble the Lasagna

  • Spread a thin layer of the white sauce on the bottom of the prepared baking dish.
  • Lay 4 lasagna noodles over the sauce.
  • Spread a third of the chicken, mushroom, and spinach mixture over the noodles, followed by a third of the white sauce.
  • Repeat the layering process two more times, finishing with a final layer of noodles and white sauce on top.

Step 6: Bake

  • Cover the lasagna with aluminum foil and bake for 25 minutes.
  • After 25 minutes, remove the foil and bake for an additional 10-15 minutes, or until the top is golden and bubbly.

Step 7: Rest and Serve

Allow the lasagna to rest for 10 minutes before slicing and serving. This helps the layers set and makes it easier to cut into neat squares.
