- 1 cup chicken broth
- 1 teaspoon Italian seasoning

🔪 Step-by-Step Instructions
Step 1: Prepare the Chicken and Spinach Mixture
1️⃣ In a large bowl, combine shredded chicken, fresh spinach, garlic powder, onion powder, salt, and black pepper.
2️⃣ Mix well and set aside while you prepare the white sauce.
Step 2: Make the Creamy White Sauce
1️⃣ In a saucepan over medium heat, melt butter.
2️⃣ Once melted, whisk in flour and cook for about 1 minute until it forms a smooth paste.
3️⃣ Gradually add milk and chicken broth, whisking constantly to avoid lumps.
4️⃣ Add Italian seasoning, nutmeg (if using), salt, and black pepper.
5️⃣ Continue stirring and cook for 3-4 minutes, until the sauce thickens.
6️⃣ Remove from heat and stir in grated Parmesan cheese until fully melted.
Step 3: Assemble the Lasagna
1️⃣ Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish.
2️⃣ Spread 1/3 cup of the white sauce at the bottom of the dish.
3️⃣ Layer 3 lasagna noodles over the sauce.
4️⃣ Spread half of the chicken and spinach mixture on top.
5️⃣ Drizzle with some more white sauce, then sprinkle mozzarella and white cheddar cheese.
6️⃣ Repeat with another layer of noodles, chicken mixture, sauce, and cheese.
7️⃣ For the final layer, place 3 noodles on top, pour the remaining sauce, and sprinkle with Parmesan cheese and extra mozzarella.
Step 4: Bake Until Golden and Bubbly
1️⃣ Cover the dish with foil and bake for 25 minutes.
2️⃣ Remove foil and bake for another 10-15 minutes, until the cheese is golden brown and bubbly.
3️⃣ Let the lasagna rest for 10 minutes before slicing—it helps the layers set!
🌿 Garnish and Serve
- Sprinkle with fresh parsley for color and flavor.
- Serve warm with garlic bread and a side salad for a complete meal!
