Preheat your oven and set it to 375°F (190°C) so it’s ready for baking.
Prepare the chicken breasts by patting them dry with paper towels to ensure they brown nicely when cooked.
In a small bowl, mix your spices — garlic powder, onion powder, Italian seasoning, salt, and black pepper — until well combined.
Season the chicken by rubbing the spice mixture evenly to coat thoroughly on all breasts.
Prepare a large baking dish, then pour melted butter to coat the bottom evenly
Arrange the seasoned chicken breasts in the baking dish on top of the butter.
Add Parmesan by sprinkling grated cheese generously over each chicken breast.
Bake the chicken in the preheated oven for 20–25 minutes, until cooked through and the internal temperature reaches 165°F (75°C).
Garnish by removing the dish from the oven, letting it rest for a few minutes, then topping with freshly chopped parsley before serving.
Serve your keto garlic parmesan chicken immediately — hot, flavorful, and ready to impress.
