Toast the panko in 1/2 tbsp olive oil in a large deep skillet over medium heat, stirring, 2 to 3 minutes until golden. Transfer to a bowl, stir in 1/4 cup parmesan and wipe out the skillet.
Pat the chicken dry and toss with Italian seasoning, paprika, salt and pepper. Heat 1 tbsp oil over medium-high, sear the chicken 2 minutes without stirring, then 2 to 3 minutes more until golden. Remove to a plate.
Reduce heat to medium, cook the garlic 30 seconds, then add marinara and broth, scraping up the browned bits.
Bring to a boil, stir in the pasta, cover and simmer on medium-low 10 to 12 minutes, stirring every 2 to 3 minutes, until the pasta is tender. Add a splash of broth if it gets dry.
Return the chicken and juices and simmer 3 to 4 minutes until it reaches 165°F. Reduce heat to low and stir in the blended cottage cheese and 2 tbsp parmesan.
Top with mozzarella, cover 2 to 3 minutes until melted (or broil 2 minutes in an oven-safe skillet).
Sprinkle with the parmesan panko and fresh basil right before serving.
