Heat 2 teaspoons olive oil in a large skillet over medium heat. Add minced garlic, Italian seasoning, and crushed red pepper flakes (if using) and sauté 2–3 minutes until fragrant.
Add the ground chicken, 1/4 teaspoon salt, and 1/4 teaspoon black pepper to the skillet. Break up the meat and cook 6–8 minutes until browned and cooked through. Transfer the cooked chicken to a plate and set aside.
Return the empty skillet to medium-high heat with 1 tablespoon olive oil. Add the whole-wheat panko and cook, stirring frequently, until the crumbs are golden and crispy. Remove from heat and set aside.
Boil the lasagna noodles according to package directions. Drain and lay flat to prevent sticking.
In a large bowl, stir together the ricotta, 1 large egg plus 1 egg yolk, 1/2 teaspoon salt, 1/2 teaspoon black pepper, 1 tablespoon chopped parsley, and 2 tablespoons chopped basil until combined.
Preheat the oven to 375°F (190°C). Spread one quarter of the marinara sauce across the bottom of a 9x13-inch baking pan.
Assemble the lasagna: place 4 noodles over the sauce, top with one-third of the cooked chicken, 1/4 cup marinara, 1/2 cup ricotta mixture, and 1/4 cup shredded mozzarella. Repeat this layering two more times.
Top the final noodle layer with the remaining chicken, marinara, ricotta, mozzarella, the toasted panko crumbs, and finish with the grated Parmesan.
Lightly oil a piece of aluminum foil and cover the pan tightly. Bake covered for 40 minutes, then remove the foil and bake uncovered for an additional 15 minutes until bubbly and golden.
Let the lasagna rest 10 minutes before cutting. Garnish with chopped fresh parsley and basil, then serve.
