Equipment

  • 1 Large skillet
  • 1 deep 9 x 13-inch baking dish
  • 1 spatula or wooden spoon
  • Measuring Cups and Spoons
  • Oven

Ingredients
  

Alfredo Sauce & Filling:

  • 2 tablespoons unsalted butter
  • 2 garlic cloves minced
  • 1 cup onion chopped
  • 10 ounces fresh baby spinach
  • 4 cups heavy cream
  • cups grated Parmesan cheese
  • 15 ounces ricotta cheese
  • ¼ teaspoon black pepper
  • teaspoons salt
  • 3 cups shredded rotisserie chicken

Lasagna Assembly:

  • 15 cooked lasagna noodles
  • 3 cups shredded mozzarella cheese

Instructions
 

  • Prepare the Aromatic Base: Start by heating a large skillet over medium-high heat.
    Once hot, add 2 tablespoons of unsalted butter, allowing it to melt completely.
    Then, incorporate 2 minced garlic cloves and 1 cup of chopped onion.
    Sauté the mixture gently, stirring occasionally, until the onions turn translucent and fragrant, and the garlic becomes golden but not burnt.
    This creates a flavorful foundation for your Alfredo sauce.
  • Wilt the Fresh Spinach: Next, add 10 ounces of fresh baby spinach to the skillet.
    Use a spatula or wooden spoon to toss the spinach gently until it wilts completely.
    This will take 2–3 minutes.
    The spinach not only adds vibrant color but also introduces a mild, earthy flavor and a boost of fiber and nutrients to your lasagna.
  • Build the Creamy Alfredo Sauce: Lower the heat to medium and slowly pour in 4 cups of heavy cream, stirring constantly to incorporate it with the butter, garlic, onion, and spinach.
    Once blended, add 1½ cups grated Parmesan cheese and 15 ounces ricotta cheese.
    Stir until the cheeses melt smoothly into the cream, forming a thick, velvety sauce.
    Season the mixture with ¼ teaspoon black pepper and 1½ teaspoons salt, adjusting to taste.
  • Incorporate the Shredded Chicken: Fold 3 cups of shredded rotisserie chicken into the Alfredo sauce.
    Mix thoroughly to ensure that every piece of chicken is coated in the creamy mixture.
    Allow the sauce to warm slightly and thicken for 2–3 minutes over low heat.
    Once ready, remove the skillet from the heat to prevent the cream from boiling.
  • Prepare the Baking Dish: Take a 9 x 13-inch deep baking dish and spread a generous spoonful of the chicken Alfredo mixture over the bottom.
    This initial layer prevents the noodles from sticking and ensures every bite has a creamy, cheesy base.
  • Assemble the First Layer of Lasagna: Lay 5 cooked lasagna noodles across the bottom of the dish, slightly overlapping them if needed.
    Spoon a portion of the chicken Alfredo mixture evenly over the noodles, making sure to cover them completely.
    Sprinkle about 1 cup of shredded mozzarella cheese over the sauce layer for an indulgent, gooey texture.
  • Repeat the Layering Process: Continue layering the lasagna noodles, Alfredo chicken mixture, and shredded mozzarella cheese until all 15 noodles are used.
    Aim for 3 layers in total, ending with a top layer of sauce and mozzarella.
    Each layer should be even, allowing the lasagna to bake uniformly and stay creamy throughout.
  • Cover and Bake: Preheat your oven to 350°F (175°C).
    Cover the lasagna with aluminum foil to prevent the cheese from burning.
    Bake for 35 minutes, allowing the flavors to meld together and the noodles to absorb the rich sauce.
  • Broil for Golden Perfection: After baking, remove the foil carefully.
    Switch your oven to broil and cook the lasagna uncovered for an additional 2–3 minutes.
    This step creates a beautifully golden and slightly crispy top layer of mozzarella, adding texture and visual appeal to your dish.
  • Rest Before Serving: Once baked, let the lasagna rest for 10 minutes before slicing.
    Resting allows the sauce to thicken slightly and ensures clean, well-defined layers when serving.
    Use a sharp knife to cut into squares or rectangles and serve hot.
  • Optional Garnishes and Serving Tips: For added freshness, sprinkle chopped parsley or a little extra Parmesan over the top.
    Pair your lasagna with a crisp side salad or garlic bread for a complete meal.
    Each bite combines tender chicken, creamy sauce, and melted cheese for a satisfying, protein-packed dinner everyone will enjoy.

Notes

  • Use rotisserie or leftover chicken to save prep time without sacrificing flavor.
  • Fresh spinach adds brightness and nutrition, but frozen spinach can be used—just thaw and squeeze out excess water.
  • Cook lasagna noodles al dente; slightly undercooked noodles will continue cooking in the oven with the sauce.
  • Grated Parmesan should be finely shredded to melt smoothly and create a creamy sauce.
  • Allow the lasagna to rest after baking for clean slices and better layering.
