How to Make White Chicken Spinach Lasagna
Step 1: Prep Oven & Pasta
Preheat the oven and cook the lasagna noodles until tender.
Drain and set aside on a tray to cool.
Step 2: Cook the White Sauce
Melt butter and whisk in flour until golden.
Slowly add milk and broth, whisking until smooth and thickened.
Stir in seasonings, Parmesan, and herbs, then remove from heat.
Step 3: Mix the Filling
Combine ricotta, Parmesan, eggs, and seasonings in a bowl.
Fold in spinach and shredded chicken until well blended.
Step 4: Assemble the Layers
Spread a thin layer of sauce in a greased baking dish.
Layer noodles, half the chicken mixture, provolone slices, and more sauce.
Repeat the layers once more.
Step 5: Finish & Bake
Top with a final layer of noodles, sauce, and cheese.
Bake until bubbly and golden. Let cool slightly before serving.
Step 6: Bake and Serve
Bake uncovered for 40–50 minutes, or until the sauce is bubbling and the cheese on top is melted and lightly browned.
Let the lasagna cool for 10–15 minutes before slicing and serving.
