Preheat the oven to 425°F (220°C) and adjust the rack to the center position. Coat a 9×13-inch baking pan with non-stick spray and set aside.
Step 2: Prepare the Sauce
Sauté the Shallots and Garlic: In a large skillet over medium heat, heat 2 tablespoons of olive oil. Add the finely chopped shallots and sauté, stirring frequently, until they begin to soften. Add the minced garlic and cook until fragrant.
Create the Roux: Add the butter to the skillet. Once melted, sprinkle the flour over the mixture and cook, stirring often, for about 2-3 minutes.
Make the Alfredo Sauce: Slowly pour in the heavy cream and whole milk, whisking until blended. Whisk in the Italian herbs, garlic powder, black pepper, and freshly grated nutmeg. Cook until the sauce has thickened.
Incorporate the Cheese: Stir in the grated Parmesan cheese until melted and combined. Cover the sauce and set aside.
Step 3: Cook the Lasagna Noodles
Boil the Noodles: Bring a large pot of salted water to a boil over high heat. Add the lasagna noodles and cook until al dente. Drain the noodles and place them on a plate to prevent sticking.
Step 4: Assemble the Lasagna
First Layer: Spread ¼ of the Alfredo sauce on the bottom of the prepared baking dish. Place 4 lasagna noodles, slightly overlapping, on the sauce. Add 1 cup of shredded Mozzarella, ⅓ of the chopped chicken, and 1 tablespoon of fresh thyme.
Repeat Layers: Repeat the layers two more times (sauce, noodles, Mozzarella, chicken, thyme), ending with a final layer of ¼ of the sauce.
Top with Cheese: Sprinkle the reserved ½ cup of shredded Mozzarella on top.
Step 5: Bake the Lasagna
Cover and Bake: Coat a sheet of aluminum foil with non-stick spray and lightly cover the dish, oil side down. Transfer the dish to the oven and bake for 30 minutes.
Finish Baking: Remove the foil and continue baking for another 15-20 minutes, or until the lasagna is bubbly around the edges and lightly browned on top.
Step 6: Rest and Serve
Rest: Allow the lasagna to rest for 10 minutes after baking. This helps it set and makes it easier to slice.
Garnish and Serve: Sprinkle with chopped fresh parsley and serve warm. Enjoy the comforting flavors of this delicious Chicken Alfredo Lasagna!
