Ingredients:
- 115g unsalted butter
- 65g all-purpose flour
- 1.2 liters whole milk, room temperature
- 2g ground nutmeg
- 6g sea salt
- 2g white pepper
- 450g whole milk ricotta
- 1 large egg, lightly beaten
- 100g grated Parmesan cheese
- 300g shredded Mozzarella cheese
- 250g fresh baby spinach, chopped
- 3 cloves garlic, minced
- 375g no-boil lasagna noodles
- 450g rotisserie chicken, shredded
Instructions:
- Melt the 115g of butter in a large saucepan over medium heat. Once it's sizzling, whisk in the 65g of flour and cook for 2 minutes until it smells slightly nutty but hasn't turned brown.
- Gradually pour in the 1.2 liters of milk, whisking constantly. Simmer for about 8-10 minutes until the sauce is thick enough to coat the back of a spoon. Stir in the nutmeg, salt, and white pepper.
- In a medium bowl, combine the 450g of ricotta, the lightly beaten egg, the 100g of Parmesan, and about half of the minced garlic. Stir until smooth and well incorporated.
- Spread about 250ml of the white sauce on the bottom of your baking dish. Place a layer of 375g no boil noodles on top, overlapping them slightly.
- Spread half of the ricotta mixture over the noodles. Top with half of the 450g shredded chicken and half of the 250g chopped spinach. Sprinkle with a handful of the 300g mozzarella.
- Add another layer of noodles, followed by more white sauce, the remaining ricotta, chicken, and spinach. Top with a final layer of noodles.
- Pour the remaining white sauce over the top layer of noodles, making sure to cover the edges completely. Sprinkle the remaining mozzarella over the top.
- Cover the dish with foil (tent it slightly so it doesn't touch the cheese) and bake at 190°C for 25 minutes. Bake until the sauce is vigorously bubbling at the edges.
- Remove the foil and bake for another 15-20 minutes until the cheese is browned and the top has a slight shatter when tapped.
- Remove from the oven and let it sit on the counter for at least 15 minutes. Wait until the internal liquids have stopped bubbling and the structure looks set.
