Place the chicken breasts in a mixing bowl and pour the Caesar dressing over them. Add in the garlic paste, grated Parmesan, lemon zest, and a pinch of salt and pepper. Toss everything together until the chicken is evenly coated with the marinade. Let it sit for at least 10 minutes to absorb the flavors.
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or a lightly greased baking rack for even crisping.
Arrange the marinated chicken breasts on the prepared baking sheet, spacing them apart to allow heat to circulate.
Place the baking sheet in the oven and bake for about 20-25 minutes, or until the chicken is cooked through and the edges start to turn golden and crispy. The internal temperature should reach 165°F (74°C).
Remove the chicken from the oven and let it rest for 5 minutes. This helps the juices redistribute, keeping the meat tender.
Slice the chicken breasts diagonally into thick strips or serve whole, then plate them up. The chicken should have a crispy, golden exterior with a juicy, tender interior that showcases the Caesar flavors.
