Ingredients

For the Sauce:

  • 3 tbsp butter
  • 2 tsp minced garlic
  • 3 tbsp flour
  • 2 ½ cups whole milk (or half-and-half)
  • Salt, to taste
  • ¼ cup grated Parmesan cheese
  • 4 oz cream cheese, softened

For the Lasagna:

  • ¾ cup ricotta cheese
  • 1 egg
  • 8 lasagna noodles, cooked according to package instructions
  • 2 cups cooked chicken, cut into bite-sized pieces
  • 2 cups shredded mozzarella cheese
  • ¼ cup grated Parmesan cheese
  • 4 cups fresh baby spinach

Instructions

Preheat and Prep:

  • Preheat your oven to 400°F (200°C).
  • Grease an 8x8-inch baking dish with oil or cooking spray.

Make the Sauce:

  • In a medium saucepan over medium heat, melt the butter.
  • Add the minced garlic and flour, stirring constantly for about 30 seconds.
  • Slowly whisk in the milk and bring to a simmer, stirring until the sauce thickens.
  • Remove from heat, then stir in the Parmesan, cream cheese, and spinach until the spinach wilts.

Assemble the Lasagna:

  • In a small bowl, whisk together the ricotta and egg until smooth.
  • Spread about ¼ cup of the sauce in the bottom of the prepared baking dish.
  • Layer 2 lasagna noodles on top, then spread with ¼ cup ricotta mixture, ⅔ cup chicken, ⅔ cup mozzarella, 1 tbsp Parmesan, and ½ cup sauce.
  • Repeat these layers two more times.
  • Finish with a final layer of noodles, pouring the remaining sauce and Parmesan cheese on top.

Bake and Serve:

  • Bake uncovered for 20-25 minutes, or until the sauce is bubbling and the cheese is golden.
  • Let the lasagna cool for 15-20 minutes before slicing and serving.
