Chicken Lasagna Ingredients
For the Pasta
• Lasagna Noodles – These create the base and hold all the delicious layers together; cook them al dente for best results.
For the Filling
• Shredded Rotisserie Chicken – The main protein source; using leftover chicken saves time and enhances flavor.
• Ricotta Cheese – Adds creamy richness; cottage cheese can be a lighter substitute if desired.
• Large Egg – Binds the ricotta mixture; omit for an egg-free variation.
• Parsley – Provides fresh flavor; swap with basil for a different herb profile.
For the Sauce
• Olive Oil – Used for sautéing onions and adding flavor; any neutral oil works if you’re in a pinch.
• Medium Onion – Adds depth of flavor when sautéed; yellow or white onions are ideal choices.
• Unsalted Butter – Essential for the béchamel sauce, making it luxuriously creamy; margarine can substitute in a pinch.
• All-Purpose Flour – Thickens the béchamel sauce; gluten-free flour can be used for a gluten-free version.
• Chicken Broth – Deepens flavor in the sauce; vegetable broth works well for a vegetarian alternative.
• Half and Half – Adds richness; equal parts of heavy cream and milk can be used as a substitute.
• Fresh Spinach – Boosts nutrition and color; if using frozen, ensure it’s well-drained to avoid a soggy texture.
• Sea Salt – Enhances flavor; regular salt is a suitable replacement.
• Black Pepper – Brings a mild heat; use white pepper instead for a different twist.
• Garlic Cloves – Provides aromatic depth; minced garlic from a jar can save you time if fresh isn’t available.
For the Topping
• Parmesan Cheese – Adds a nutty finish; Pecorino Romano can also be an excellent alternative.
• Mozzarella Cheese – Ensures gooey and stretchy bites; a blend of mozzarella and provolone offers a fun twist.

Step‑by‑Step Instructions for Creamy Chicken Lasagna with Spinach and Cheese
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that your creamy Chicken Lasagna bakes evenly and develops a delightful golden crust on top. While the oven heats up, gather and prepare your ingredients so that everything is ready to go for a seamless cooking experience.
Step 2: Cook the Lasagna Noodles
In a large pot of salted boiling water, cook the lasagna noodles according to the package instructions until al dente, usually around 8–10 minutes. Once cooked, drain and set them aside on a lightly greased baking sheet to cool, preventing them from sticking together as you prepare the filling and sauce.
Step 3: Sauté the Onion
Heat a medium-sized pot over medium heat and pour in a splash of olive oil. Add the finely chopped onion and sauté for about 5 minutes until it becomes translucent and fragrant. This step is crucial for building flavor in your creamy Chicken Lasagna, so stir occasionally to guard against browning.
Step 4: Make the Béchamel Sauce
Add the butter to your pot with the sautéed onions and let it melt. Whisk in the flour for about 1 minute until it turns golden, then gradually whisk in the chicken broth and half and half, stirring constantly. Continue cooking for around 5-7 minutes until the mixture thickens and bubbles gently, indicating it’s ready for the next layer.
Step 5: Incorporate Spinach and Seasoning
Stir in the minced garlic and coarsely chopped spinach into the béchamel sauce, cooking for an additional 2-3 minutes until the spinach wilts. Season your mixture with sea salt and black pepper to enhance the flavors. This rich spinach sauce is a key component of your Chicken Lasagna, contributing both creaminess and nutrition.
Step 6: Prepare the Ricotta Mixture
In a separate bowl, combine ricotta cheese, a large egg, and chopped parsley. Mix in half of the mozzarella and Parmesan cheeses, creating a creamy filling that will provide a luscious layer in your Chicken Lasagna. Ensure everything is well incorporated for the best texture and flavor.
Step 7: Assemble the Lasagna
In a 9×13 inch baking dish, spread a thin layer of the béchamel sauce over the bottom. Layer with cooked lasagna noodles, followed by a layer of the ricotta mixture, shredded rotisserie chicken, and béchamel sauce. Repeat this layering process until all ingredients are used, finishing with a final layer of noodles topped with remaining mozzarella cheese.
Step 8: Bake the Lasagna
Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 45 minutes until heated through and bubbly. For a crispy, golden top, remove the foil and broil for an additional 2-3 minutes until the cheese is perfectly browned and inviting.
Step 9: Rest Before Serving
Once the creamy Chicken Lasagna is out of the oven, let it rest for at least 10 minutes. This resting period allows the layers to set, making it easier to slice and serve. The aroma wafting through your kitchen will have everyone eagerly waiting for a hearty slice of this delicious home-cooked meal.
