Ingredients
For the Filling
2 cups cooked chicken breast, shredded or diced
8 ounces cremini or button mushrooms, sliced
3 cups fresh baby spinach
1 medium onion, finely chopped
2 tablespoons minced garlic
2 tablespoons olive oil
1 teaspoon dried oregano
1 teaspoon dried basil
½ teaspoon salt
½ teaspoon black pepper
¼ teaspoon red pepper flakes (optional)
For the Creamy White Sauce
4 tablespoons butter
¼ cup all-purpose flour
2½ cups whole milk
1 cup chicken broth
½ teaspoon salt
¼ teaspoon black pepper
Pinch of ground nutmeg
¾ cup grated Parmesan cheese
For the Cheese Layer
15 ounces ricotta cheese
1 large egg
2 tablespoons chopped fresh parsley
¼ teaspoon salt
¼ teaspoon black pepper
For Assembly
9 lasagna noodles, cooked according to package directions (or oven-ready)
2½ cups shredded mozzarella cheese
Extra Parmesan cheese for topping
Fresh parsley or basil for garnish
Instructions
Heat olive oil in a large skillet over medium heat. Add the chopped onion and cook until soft and translucent, about 4 minutes. Stir in the garlic and cook for another minute until fragrant.
Add the sliced mushrooms and sauté until they release their moisture and become golden brown. Stir in the spinach and cook just until wilted.
Mix in the cooked chicken, oregano, basil, salt, black pepper, and red pepper flakes if using. Stir everything together and remove from the heat.
For the béchamel sauce, melt the butter in a saucepan over medium heat. Whisk in the flour and cook for about 2 minutes, stirring constantly to create a smooth roux.
Gradually pour in the milk followed by the chicken broth while whisking continuously. Continue cooking until the sauce thickens into a smooth, creamy consistency.
Season with salt, pepper, and a pinch of nutmeg. Stir in the grated Parmesan cheese until completely melted. Remove from the heat.
In a separate bowl, combine the ricotta cheese, egg, parsley, salt, and black pepper until smooth.
Preheat your oven to 375°F (190°C).
Spread a thin layer of white sauce over the bottom of a 9×13-inch baking dish.
Arrange a layer of lasagna noodles over the sauce. Spread one-third of the ricotta mixture over the noodles, followed by one-third of the chicken and mushroom filling. Spoon over some béchamel sauce and sprinkle with mozzarella cheese.
Repeat the layers two more times until all ingredients are used.
Finish with the remaining béchamel sauce, mozzarella cheese, and an extra sprinkle of Parmesan.
Cover loosely with foil and bake for 35 minutes. Remove the foil and continue baking for another 15 minutes until the cheese is golden and bubbly.
Allow the lasagna to rest for 15 minutes before slicing. Garnish with chopped parsley or fresh basil and serve warm.
Tips
Allow the béchamel sauce to thicken before assembling the lasagna so it holds the layers together perfectly.
Cook mushrooms until their moisture has evaporated to prevent a watery casserole.
Rotisserie chicken is a great shortcut and adds extra flavor.
Let the spinach wilt completely before mixing it into the filling.
Freshly grated Parmesan melts more smoothly than pre-shredded cheese.
Avoid overcooking the noodles since they continue cooking in the oven.
Resting the lasagna before serving helps create neat, firm slices.
Use whole milk for the richest and creamiest white sauce.
Lightly grease the baking dish to prevent sticking.
Covering the lasagna during the first stage of baking keeps the cheese from browning too quickly.
Variations
Replace chicken breast with shredded rotisserie chicken for faster preparation.
Use cooked ground chicken or turkey for a different texture.
Add sautéed broccoli, zucchini, or asparagus for extra vegetables.
Mix Gruyère or Fontina cheese with mozzarella for a richer flavor.
Swap ricotta with cottage cheese for a lighter version.
Include cooked bacon pieces for a smoky touch.
Add sun-dried tomatoes for a sweet and tangy flavor contrast.
Use whole wheat lasagna noodles for added fiber.
Prepare individual lasagnas in ramekins for elegant single servings.
Make it extra creamy by replacing part of the milk with heavy cream.
Q&A
Can I make this lasagna ahead of time?
Yes. Assemble it up to 24 hours in advance, refrigerate, and bake when ready.
Can I freeze it?
Absolutely. Wrap tightly and freeze for up to 3 months. Thaw overnight before baking.
Can I use frozen spinach?
Yes. Thaw and squeeze out all excess water before adding it to the filling.
Do I have to cook oven-ready noodles first?
No. Simply follow the package directions, as most oven-ready noodles can be layered without boiling.
What mushrooms work best?
Cremini, button, or baby bella mushrooms all provide excellent flavor and texture.
How do I know when it’s done?
The cheese should be golden brown, bubbling around the edges, and the center should be hot throughout.
Can I use low-fat cheese?
Yes, although the lasagna will be slightly less creamy.
How should leftovers be stored?
Store covered in the refrigerator for up to 4 days and reheat individual portions in the microwave or oven.
