Grease a 9×13-inch baking dish or spray with nonstick cooking spray. In the prepared dish, combine chicken with lemon juice, olive oil, and all herbs and spices. Let marinate at room temperature for 30 minutes while preheating oven to 375°F.
Add the uncooked rice, grated zucchini, and chicken broth to the pan with the marinated chicken. Stir everything together well.
Cover the dish tightly with foil and bake for 40 minutes, or until rice is tender and liquid is mostly absorbed. If needed, bake 5-10 minutes longer.
Fluff the rice with a fork, taste and adjust seasoning if needed. Serve topped with tzatziki sauce, fresh herbs, and a squeeze of lemon.
Notes
Only use long grain white rice – brown rice, wild rice, or instant rice won’t work with these liquid ratios and cooking times.
Use smoked paprika specifically for that authentic charred flavor similar to grilled souvlaki.
Covering the dish tightly is crucial to prevent steam from escaping while cooking.
