Ingredients:
- 3 cups cooked shredded chicken breast (approx. 450g)
- 1 tbsp extra virgin olive oil
- 2 cloves garlic, minced
- 5 oz fresh baby spinach, wilted and squeezed dry
- 15 oz whole milk ricotta cheese
- 1 large egg, lightly beaten
- 4 tbsp unsalted butter
- 0.25 cup all-purpose flour
- 3 cups whole milk, room temperature
- 1 cup grated Parmesan cheese, divided
- 0.25 tsp ground nutmeg
- 0.5 tsp salt
- 0.25 tsp white pepper
- 15 lasagna sheets, no-boil or par-boiled
- 3 cups shredded mozzarella cheese
- 0.5 cup shredded Provolone cheese
Instructions:
- Heat olive oil in a pan, add minced garlic for 30 seconds, then toss in 3 cups shredded chicken and 5 oz spinach until the spinach is fully wilted.
- In a small bowl, combine 15 oz ricotta with 1 lightly beaten egg and 0.5 cup Parmesan until the mixture is smooth and uniform.
- Melt 4 tbsp butter in a saucepan over medium heat, then whisk in 0.25 cup flour until it bubbles and smells slightly nutty.
- Slowly pour in 3 cups milk while whisking constantly until the sauce thickens and coats the back of a spoon.
- Stir in 0.5 cup Parmesan, 0.25 tsp nutmeg, salt, and white pepper until the cheese is completely melted and silky.
- Spread 0.5 cup of the white sauce on the bottom of a 9x13 dish, then top with 3-5 lasagna sheets until the bottom is covered.
- Layer half of the chicken and spinach mixture, followed by dollops of the ricotta mixture and a sprinkle of mozzarella until the layer is even.
- Add more sauce, sheets, the remaining chicken, and ricotta, then finish with a final layer of sheets until you reach the top of the dish.
- Pour the remaining sauce over the final sheets and cover generously with 3 cups mozzarella and 0.5 cup Provolone until every corner is coated.
- Bake at 375°F for 45 minutes, then let it sit for 10 minutes until the cheese is set and doesn't slide.
