Preheat your oven to 375°F (190°C) and grease the baking dish with olive oil.

Combine diced chicken, chopped zucchini, and sliced onion in a large mixing bowl.

Drizzle olive oil over the mixture and add minced garlic, smoked paprika, cumin, oregano, salt, and pepper. Toss to combine.

Transfer the mixture to the baking dish, spreading into an even layer.

Bake for 25-30 minutes until chicken is 165°F and zucchini is tender.

Let rest for 3-4 minutes, then garnish with cilantro or parsley and serve with rice.
