In a small bowl, stir together ricotta and egg and season with salt and pepper.
In a large baking dish, spread a thin layer of sauce.
Add a layer of lasagna noodles, slightly overlapping, and top with about a third of ricotta mixture, a third of tomatoes, a third of the basil, a third of the cooked chicken, another layer of sauce, and a third of mozzarella.
Repeat with three layers, ending with mozzarella.
Bake until bubbly and golden, 35 minutes.
Garnish with more basil and a drizzle of balsamic glaze and serve.
