Season the chicken breasts with salt and pepper.
Grill or pan-sear the chicken until fully cooked, about 6-8 minutes per side.
Allow the chicken to rest for a few minutes before slicing it into thin strips.
Preheat the oven to 375°F (190°C).
In a bowl, toss the bread cubes with olive oil, garlic powder, and salt.
Spread the bread cubes on a baking sheet and bake for 10-15 minutes, or until golden and crispy.
In a small bowl, whisk together mayonnaise, grated Parmesan, minced garlic, lemon juice, Dijon mustard, Worcestershire sauce, salt, and pepper until smooth and well combined.
In a large salad bowl, combine the chopped romaine lettuce, sliced chicken, croutons, and grated Parmesan cheese.
Drizzle the dressing over the salad and toss to coat everything evenly.
Serve the Chicken Caesar Salad immediately, garnished with extra Parmesan cheese and additional toppings if desired.
