01 - Preheat your oven broiler or toaster oven to high heat setting.
02 - Heat olive oil in a skillet over medium heat. Add panko breadcrumbs and toast until golden brown, approximately 2 minutes. Remove from heat and set aside.
03 - Combine the chopped cooked chicken with garlic powder, Italian seasoning, salt, and black pepper. Toss until evenly coated.
04 - Divide the seasoned chicken evenly between two large oven-safe serving bowls.
05 - Spoon marinara sauce over the chicken in each bowl. Top with dollops of cottage cheese, then sprinkle with mozzarella and Parmesan cheeses.
06 - Place the bowls under the preheated broiler and cook until the cheese melts and becomes bubbly, about 3 to 5 minutes. Watch closely to prevent burning.
07 - Carefully remove the bowls from the oven. Sprinkle the toasted breadcrumbs and fresh basil over the top. Serve immediately while hot.
