Easy Creamy White Chicken Lasagna with fresh spinach and marinated roasted red pepper is the ultimate comfort food loaded with layers of fresh delicious Italian flavors. The lighter white cream sauce, savory rotisserie chicken, six different cheeses, and fresh vegetables make this tasty dish a favorite treat your whole family will love.

This dish could be called “Christmas Lasagna” with all its beautiful colors from fresh green spinach and sweet red peppers encased in the delicious white alfredo sauce. Serve it instead of a traditional ham for the holidays with a homemade Caesar Salad and a crusty loaf of garlic bread.

WHY YOU’LL LOVE THIS CHICKEN SPINACH LASAGNA

  • Simple, easy ingredients: This recipe uses a few already prepared store-bought ingredients that make it easier to assemble but it still tastes like it took you all day. Store-bought pesto sauce, no-boil lasagna sheets, Italian seasoning blend, and fresh rotisserie chicken…these convenient items save you at least 2 hours in the kitchen!
  • Rich Flavor: The combination of tender chicken, light and creamy alfredo sauce, fresh spinach, and sweet red peppers creates a complex and savory flavor profile. The flavors offer a balance of richness and freshness.
  • Healthier Ingredients: Spinach is packed with nutrients like vitamins A, C, and K, as well as iron and antioxidants. Red peppers are rich in vitamin C and other antioxidants. When combined with lean chicken, these ingredients make for a wholesome, nutrient-dense meal.
  • Visually Beautiful: Some say “You eat with your eyes first”. The vibrant colors of the red peppers and green spinach against the creamy white sauce make this dish delicious before you even taste it.
  • Easy to Customize: You can adjust the ingredients and seasoning to suit personal preferences allowing for creativity in the kitchen.

WHAT YOU’LL NEED FOR THIS CREAMY WHITE CHICKEN LASAGNA RECIPE

Ingredients:

  • Chicken: 1 store-bought rotisserie chicken. Rotisserie chicken is the best time saver in the kitchen. It’s cheaper to buy rotisserie chicken than a raw whole chicken or individual chicken pieces.
  • Lasagna Noodles: I use no-boil oven-ready noodles. These make this white lasagna so much easier and save time. If you can’t find these in the grocery store then buy the traditional lasagna noodles and follow the directions on the back of the box.
  • Fresh Vegetables: fresh baby spinach. White, yellow, or red onion (I prefer yellow). 2-3 cloves of garlic crushed or finely minced. Store-bought jarred whole roasted red peppers. Marinated sliced red peppers are too mushy and will disintegrate in the lasagna.
  • Dairy-6 kinds of cheese: mozzarella cheese, parmesan cheese, ricotta cheese (you can use light ricotta), cottage cheese, cream cheese, and provolone cheese slices. 2% or whole milk. Real salted or unsalted butter.
  • ​Egg
  • Flour
  • Pesto Sauce: store-bought pesto sauce. Adding pesto sauce to the ricotta mixture is so good and helps make this dish special.
  • Seasonings: any Store-bought Italian seasoning blend. Or mix up an oregano-thyme mixture. 1 tablespoon of oregano and 1 teaspoon of thyme. Salt and pepper to taste.

HOW TO MAKE CREAMY WHITE CHICKEN LASAGNA RECIPE

Instructions:

Make the ricotta sauce first:

In a medium bowl, mix ricotta cheese, cottage cheese, pesto sauce, and 1 egg. Make sure these ingredients are well incorporated. Set aside.

Step 1 making ricotta cheese filling.

Make the White Sauce:

  • Melt Butter: In a large non-stick skillet saucepan, melt the butter over medium heat.
  • Add the garlic and onions: Once the butter is melted, add the minced garlic and chopped onions. Saute for about 3-4 mins. They should be softer but not too soft.
  • Add Flour: Add the flour and whisk continuously for about 2 minutes until the mixture turns a light golden color. Note: flour and butter will cake on the onions and garlic but that’s ok.

  • Pour in Milk: Gradually pour in the milk while whisking constantly to avoid lumps. Turn down the heat a little until the lumps disappear.

  • Add the cream cheese: Dice the cream cheese and add to the sauce. Let the sauce simmer on medium heat until it starts to thicken.

  • Season and Thicken: Add 1/3 cup shredded parmesan cheese. Add Italian seasonings (Oregano and Thyme), and salt and pepper if using. Stir and let the sauce simmer gently, stirring occasionally, until it thickens and coats the back of a metal spoon.. It should be the consistency of wall paint, LOL!  
  • Add spinach: Turn off the heat Remove from heat and add fresh baby spinach. Note: scoop the sauce over the spinach leaves until they’re just wilted.

  • Add the sliced roasted red peppers and gently mix.

Assembling the Lasagna:

  • Preheat the Oven: Preheat your oven to 400o degrees. Grease a 9″x9″ inch baking dish with nonstick cooking spray or 1 teaspoon of olive oil. Note: you can use a 9″x13″ casserole pan too. The lasagna will have one less layer or you could easily double the recipe and have 3 or 4 layers.
  • Layering: Spread a thin layer of spinach white sauce on the bottom of the baking dish. Place two no-boil lasagna sheets over the sauce.
Layer 1 of sauce. Layer 2 with noodles on top of sauce.
  • Spread: Spread 1/2 cup of the ricotta-cottage cheese mixture on the no-boil lasagna sheets.
  • Add Fillings: Layer 1/3 of the chicken on top of the ricotta mixture. 
  • Sprinkle: a portion of mozzarella and Parmesan cheese over the fillings. Lightly sprinkle oregano and thyme or Italian seasoning mix over cheeses.

  • Spread: 1/2 cup of creamy spinach sauce on top of cheeses.
  • Repeat: Add another layer of two lasagna noodles, ricotta -cottage cheese filling, 1/2 cup of chicken, cheese, seasoning, and then sauce again.

  • Bake: Bake the lasagna dish uncovered in the preheated oven for 40-45 minutes. Turn the oven off and let the lasagna sit in the oven for an additional 10-15 minutes.
  • Serve: Allow the lasagna to cool for a few minutes before slicing. Garnish with fresh herbs like parsley if desired and serve hot.
