For the Lasagna

- 3 cups cooked, shredded chicken
- 2 cups shredded mozzarella cheese, divided
- 1 cup ricotta cheese
- 1/2 cup freshly grated Parmesan cheese
- 2 cups fresh spinach, roughly chopped

- 1 tablespoon olive oil
- 1/2 teaspoon Italian seasoning
- Salt and black pepper, to taste
For the Creamy White Sauce

- Salt and black pepper, to taste
How to Make Chicken Lasagna
Step 1: Prepare the Lasagna Noodles
Cook the lasagna noodles according to the package instructions if they are not oven-ready. Drain them carefully and arrange them on a clean surface so they do not stick together. Avoid overcooking because the noodles will continue cooking in the oven.
Step 2: Prepare the Chicken and Spinach
Heat the olive oil in a skillet over medium heat. Add the minced garlic and cook for about 30 seconds until fragrant. Add the chopped spinach and cook until wilted. Stir in the cooked shredded chicken, Italian seasoning, salt, and black pepper. Remove from the heat and set aside.
Step 3: Make the Creamy White Sauce
Melt the butter in a saucepan over medium heat. Whisk in the flour and cook for about one minute, stirring constantly. Gradually add the warm milk while whisking to prevent lumps.
Continue cooking for approximately 5–8 minutes, stirring frequently, until the sauce thickens enough to coat the back of a spoon. Stir in the Parmesan, nutmeg if using, salt, and black pepper. Remove from the heat.
Step 4: Prepare the Ricotta Mixture
In a bowl, combine the ricotta cheese with a small pinch of salt and black pepper. Stir until smooth. This creamy layer helps give the chicken lasagna its rich texture.
Step 5: Assemble the Lasagna
Preheat the oven to 375°F (190°C). Lightly grease a 9-by-13-inch baking dish.
- Spread a thin layer of white sauce across the bottom of the dish.
- Arrange a layer of lasagna noodles over the sauce.
- Spread some of the ricotta mixture over the noodles.
- Add a portion of the chicken and spinach mixture.
- Spoon over some white sauce and sprinkle with mozzarella.
- Repeat the layers until the ingredients are used, finishing with white sauce, mozzarella, and Parmesan on top.
Step 6: Bake Until Golden and Bubbly
Cover the baking dish loosely with foil and bake for 25 minutes. Remove the foil and bake for another 15–20 minutes, or until the cheese is melted, the edges are bubbling, and the center is hot.
If the top needs more color, broil briefly while watching carefully to prevent burning.
Step 7: Rest and Serve
Allow the lasagna to rest for 10–15 minutes before slicing. This helps the layers settle and makes serving easier. Garnish with fresh parsley or basil if desired, then serve warm.
Tips for the Best Chicken Lasagna
- Use flavorful chicken: Seasoned roasted or rotisserie chicken is a convenient option.
- Make a smooth sauce: Add the milk gradually and whisk continuously.
- Avoid watery spinach: Cook fresh spinach until wilted. If using frozen spinach, thaw it and squeeze out excess liquid.
- Don’t use too much sauce: Each layer should be moist but not swimming in liquid.
- Let it rest: Resting before slicing helps the lasagna hold its shape.
- Check the center: Make sure the dish is thoroughly heated before serving.
Easy Variations
Chicken and Mushroom Lasagna
Sauté sliced mushrooms with the garlic before adding the spinach. Their savory flavor pairs beautifully with creamy white sauce.
Extra-Cheesy Chicken Lasagna
Add a little extra mozzarella between the layers or mix a small amount of provolone into the cheese topping.
Chicken Alfredo Lasagna
For a richer variation, replace part of the béchamel with your favorite Alfredo sauce. Adjust the seasoning to taste.
Make It with Leftover Chicken
This recipe is an excellent way to use leftover roasted chicken. Remove the skin and bones, shred the meat, and season it before layering.
What to Serve with Chicken Lasagna
Because chicken lasagna is rich and creamy, lighter side dishes make a great pairing. Try serving it with:
- A fresh green salad with lemon vinaigrette
- Roasted broccoli or green beans
- Garlic bread or crusty Italian bread
- Steamed vegetables
How to Store and Reheat Leftovers
Refrigeration
Allow leftovers to cool promptly, then place them in an airtight container and refrigerate within two hours. Store for up to 3–4 days.
Freezing
Freeze individual portions or the fully assembled, unbaked lasagna in a freezer-safe container. For the best quality, use within 2–3 months. Thaw frozen leftovers in the refrigerator before reheating when practical.
Reheating
Cover individual portions and reheat in the oven at 350°F (175°C) until hot throughout. Add a spoonful of milk or white sauce if the lasagna seems dry. Leftovers should reach 165°F (74°C) when reheated.
Frequently Asked Questions
Can I make chicken lasagna ahead of time?
Yes. Assemble the lasagna, cover it, and refrigerate for up to 24 hours before baking. If baking directly from the refrigerator, allow extra time and check that the center is thoroughly hot.
Can I use rotisserie chicken?
Absolutely. Rotisserie chicken is convenient and adds plenty of flavor. Shred it and remove any skin or bones before using it in the filling.
Can I use frozen spinach?
Yes. Thaw it completely and squeeze out as much liquid as possible before mixing it with the chicken.
Why is my chicken lasagna watery?
Excess liquid can come from watery spinach, a sauce that is too thin, or slicing the lasagna before it rests. Drain vegetables well, cook the sauce until thickened, and allow the lasagna to rest before serving.
Can I freeze chicken lasagna?
Yes. Freeze it in an airtight, freezer-safe container. Label it with the date and reheat thoroughly after thawing.
