👨‍🍳 Instructions

1. 1--- Prepare the Pan: ---
2. 2If baking immediately, preheat oven to 400°F. Spray a 9x13-inch baking dish with cooking spray or lightly grease with oil.
3. 3--- Make the Sauce: ---
4. 4Melt butter in a medium-large saucepan or Dutch oven over medium heat. Add the onion and cook for 4-5 minutes, until softened.
5. 5Add garlic and Italian seasoning; cook 30 seconds until fragrant.
6. 6Add white wine and bring to a boil. Cook 3-5 minutes until reduced to a few tablespoons.
7. 7Add flour and reduce the heat to low. Cook 2 minutes, stirring constantly.
8. 8Slowly add milk, salt, and pepper, whisking until smooth. Increase the heat slightly and bring to a gentle boil. Simmer for 1-2 minutes, until slightly thickened (to the consistency of heavy cream).
9. 9Reduce the heat to low. Stir in 1 cup Parmesan until melted and smooth.
10. 10Spread 1 cup of sauce in the bottom of the prepared pan.
11. 11Add chicken, spinach, and rosemary to the remaining sauce. Stir over low heat until spinach is wilted. Cover the pan for a few minutes, if needed to wilt the spinach.
12. 12--- Assemble the lasagna: ---
13. 13Divide the ravioli into two portions. Arrange half of the ravioli over the sauce in the pan.
14. 14Spread half of the chicken-spinach mixture over the ravioli. Sprinkle with half of the mozzarella.
15. 15Repeat with the remaining ravioli, sauce, and mozzarella. Sprinkle the remaining ¼ cup Parmesan over the top.
16. 16--- Bake: ---
17. 17Cover with foil and bake 35-45 minutes until hot and the cheese is melted. (Check at 35 minutes - if the cheese is not melted, give it a little longer.)
18. 18Remove the foil. Top with finely chopped sun-dried tomatoes and a light dusting of Italian seasoning. Bake for another 10–15 minutes, until bubbly and lightly golden.
19. 19Let rest 15 minutes before slicing and serving.
