Preheat your oven to 400°F (200°C). Pound the boneless skinless chicken breasts to an even thickness using a meat mallet or rolling pin.
In a large mixing bowl, combine grated parmesan cheese, paprika, all-purpose flour, salt, pepper, and garlic powder. Mix thoroughly.
In another bowl, beat the eggs. Dip each chicken breast into the beaten eggs, then coat fully in the parmesan mixture.
In the same bowl used for the parmesan mixture, add chopped broccoli, red and yellow peppers, and baby red potatoes. Drizzle with olive oil and season with salt and pepper. Toss to coat.
Line a baking sheet with parchment paper. Place coated chicken breasts on one side and spread the vegetables on the other side in a single layer.
Bake in the preheated oven for 25-30 minutes until chicken is golden brown and reaches 165°F (75°C), and vegetables are tender and caramelized.
Remove from oven and let cool for a few minutes. Serve the crispy parmesan paprika chicken alongside the roasted vegetables and enjoy.
