Ingredients:
- 5 lbs Boneless, skinless chicken breasts, diced
- 2 Tbsp Olive Oil
- 1 medium Yellow Onion, finely chopped
- 10 oz Cremini Mushrooms, sliced
- 3 cloves Garlic, minced
- 1 tsp Dried Thyme
- 1/2 cup Dry White Wine OR Chicken Broth
- 1/4 cup Fresh Parsley, chopped
- Salt and Freshly Ground Black Pepper, to taste
- 6 Tbsp Unsalted Butter
- 6 Tbsp All-Purpose Flour
- 4 cups Whole Milk, warmed slightly
- 1/4 tsp Freshly Grated Nutmeg
- Salt and White Pepper, to taste
- 12 No-Boil Lasagna Noodles
- 15 oz Whole Milk Ricotta Cheese
- 2 cups Shredded Mozzarella Cheese, divided
- 1 cup Grated Parmesan Cheese, divided
Instructions:
- Prepare the Chicken: Season diced chicken. Sauté in olive oil in a large skillet until golden brown and cooked through (165°F internal temp). Remove chicken and set aside.
- Sauté Aromatics: Add onion to the same skillet; cook until soft. Add mushrooms and thyme; cook until mushrooms release liquid and it evaporates. Add garlic; cook for 1 minute until fragrant.
- Deglaze: Pour in white wine/broth, scraping up any browned bits from the bottom of the pan. Let reduce slightly. Return chicken to the pan, stir, and set aside.
- Make the Béchamel (Roux): In a medium saucepan, melt butter over medium heat. Whisk in flour vigorously for 2 minutes to cook out the raw flour taste (creating the roux).
- Add Milk: Slowly stream in the warmed milk while whisking constantly to prevent lumps. Continue whisking until the mixture thickens enough to coat the back of a spoon (about 8-10 minutes).
- Season Sauce: Remove from heat. Stir in nutmeg, salt, and white pepper. Taste and adjust seasoning.
- Prepare Ricotta Mix: In a small bowl, gently mix the ricotta with 1/2 cup Parmesan and half of the parsley. Season lightly.
- Preheat & Assemble Base: Preheat oven to 375°F (190°C). Lightly grease a 9x13 baking dish. Spread a thin layer of Béchamel (about 1 cup) across the bottom.
- First Layer Assembly: Arrange a layer of lasagna noodles over the sauce. Spread half of the ricotta mixture over the noodles. Top evenly with half of the chicken/mushroom mixture. Sprinkle with 1/3 of the remaining Mozzarella.
- Second Layer Assembly: Spoon about 1.5 cups of Béchamel over the filling. Top with another layer of noodles. Repeat the ricotta, chicken/mushroom, and mozzarella layering.
- Final Top Layer: Place the final layer of noodles on top. Pour the remaining Béchamel evenly over the top, ensuring all noodles are covered. Sprinkle with the remaining Mozzarella and Parmesan cheese.
- Bake: Cover the dish tightly with foil. Bake for 30 minutes. Remove the foil and bake for an additional 10–15 minutes, until the cheese is golden brown and bubbling.
- Rest & Serve: Let the lasagna rest on the counter for 15 minutes before slicing. Garnish with remaining parsley.
