Heat 2 teaspoons olive oil in a large skillet over medium heat. Add the 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. Break the meat up with a wooden spoon and cook 6–8 minutes until browned and cooked through. Transfer chicken to a plate and set aside.
Return the skillet to medium-high heat, add 1 tablespoon olive oil, then add the whole wheat panko. Cook, stirring frequently, until the crumbs are golden and crispy. Remove from heat and transfer to a small bowl.
Bring a large pot of salted water to a boil and cook 12 lasagna noodles according to package directions. Drain and lay noodles flat to prevent sticking.
In a large bowl, combine 2 1/2 cups ricotta, the large egg plus 1 egg yolk, 1/2 teaspoon salt, 1/2 teaspoon black pepper, 1 tablespoon chopped parsley, and 2 tablespoons chopped basil. Stir until smooth and set aside.
Preheat the oven to 375°F (190°C). Spread 1/4 of the marinara sauce across the bottom of a 9x13 pan.
Assemble the lasagna: layer 4 noodles over the sauce, spread one-third of the cooked chicken over the noodles, spoon 1/4 cup marinara, dollop 1/2 cup ricotta, and sprinkle 1/4 cup mozzarella. Repeat this layering two more times.
Top the final layer of noodles with the remaining chicken, remaining marinara, remaining ricotta, remaining mozzarella, the toasted panko crumbs, and finish with the grated Parmesan.
Lightly oil a sheet of aluminum foil and tightly cover the lasagna. Bake 40 minutes, then remove the foil and bake uncovered 15 more minutes until bubbly and golden.
Let the lasagna rest 10 minutes before cutting. Garnish with chopped fresh parsley and basil and serve.
