Instructions
Prepare the ricotta mixture by combining ricotta, mozzarella, parmesan, egg, and black pepper in a medium bowl. Mix until smooth and set aside.
Remove the skin from the rotisserie chicken and shred the meat with two forks. Set aside.
Bring a large pot of water to a boil over high heat. Add salt to the water, then cook the lasagna noodles until al dente. Drain and set aside.
In a large skillet, melt the butter over medium heat. Add the diced onion and garlic, cooking for about 4 minutes until softened.
Stir in the flour and cook for 1-2 minutes until it turns light brown. Slowly add chicken broth, whisking constantly to remove any lumps. Mix well.
Add the Italian seasoning, salt, black pepper, garlic powder, heavy cream, and parmesan to the sauce. Stir to combine, then add the chopped spinach. Stir again until the spinach wilts into the sauce.
In a 9x13-inch casserole dish, spread 1 cup of the sauce on the bottom. Layer three lasagna noodles on top. Spread ⅓ of the ricotta mixture over the noodles, followed by ⅓ of the shredded chicken. Repeat the layers twice more, finishing with the remaining sauce.
Top with the shredded mozzarella and bake for 25 minutes, until the cheese is melted and bubbly. Finish the lasagna by broiling it for 3-4 minutes until the top is golden brown.
Top with chopped parsley, slice into 9 pieces, and serve.
Notes
For added flavor, consider using fresh herbs in the ricotta mixture.
