Start by preheating your oven to 400°F (200°C). This ensures that your dish cooks evenly.
In a mixing bowl, season the chicken breasts with Italian seasoning, salt, black pepper, and 1 tablespoon of olive oil. Toss to coat the chicken evenly.
Place the seasoned chicken breasts in the baking dish. Make sure they are evenly spaced for proper cooking.
Sprinkle the grape tomatoes and minced garlic around the chicken in the dish. Their juices will meld beautifully with the chicken as it bakes.
Take your block of feta cheese and crumble it over the chicken and tomatoes. This is where the magic happens!
Drizzle lemon juice over the top, then sprinkle with dried thyme, dried basil, and onion powder. The flavors will intensify during baking.
Pour the heavy cream evenly over the entire dish to create a luscious sauce that will soak into the chicken.
Drizzle the remaining 1 tablespoon of olive oil over the top and place the dish in the preheated oven. Bake for 25-30 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).
Once out of the oven, let the dish rest for a few minutes before garnishing with the fresh basil leaves. Serve warm and enjoy the explosion of flavors!
