Dump-and-bake chicken tzatziki casserole layers seasoned raw chicken, cherry tomatoes, and red onion over cooked rice, then covers everything in tzatziki sauce and feta before baking, ready in about 50 minutes. Spreading the tzatziki over the top before baking rather than serving it on the side means it partially bakes into the dish, mellowing its tang while still keeping the Mediterranean flavor profile.
Dump-and-Bake Chicken Tzatziki Casserole
Ingredients
- 1 1/2 lbs boneless, skinless chicken breast or thighs, cubed
- 2 cups cooked rice (white or brown)
- 1 1/2 cups store-bought or homemade tzatziki sauce
- 1/2 cup crumbled feta cheese
- 1 cup cherry tomatoes, halved
- 1/2 red onion, thinly sliced
- 1 tbsp olive oil
- 1/2 tsp dried oregano
- Salt and pepper to taste
- Fresh parsley or dill for garnish (optional)
Instructions
- Preheat oven to 375°F (190°C). Grease a 9×13-inch casserole dish.

- In a bowl, toss chicken with olive oil, oregano, salt, and pepper. Layer on top of rice.
- Add cherry tomatoes and red onion over the chicken.
- Spoon tzatziki sauce evenly across the top. Sprinkle with crumbled feta.
- Cover with foil and bake for 30 minutes. Uncover and bake an additional 10–15 minutes, or until chicken is cooked through and bubbly.

Recipe Notes
- Use rotisserie chicken to save even more time—just reduce bake time by 10 minutes.

Why you'll love this
- Spreading the rice across the bottom of the dish first, then layering the chicken and vegetables on top, means the rice absorbs juices released by the chicken and tomatoes as everything bakes.
- Covering the dish with foil for the first 30 minutes keeps the chicken from drying out while it cooks through, with the final uncovered stage letting the top set and the sauce reduce slightly.
Tips for the best result
- Cube the chicken evenly, as the recipe implies, so all the pieces reach doneness at the same time within the covered baking window.
- Use rotisserie chicken to save time, as the recipe's own notes suggest, reducing the bake time by about 10 minutes since it's already cooked.
Troubleshooting
The dish looks watery after baking.
Cherry tomatoes release liquid as they bake. This is expected, but for a thicker result, halve the tomatoes and let excess seeds and juice drain briefly before adding them to the dish.
The chicken isn't fully cooked at the end of the bake time.
Cube sizes matter here - if pieces were cut larger than intended, extend the covered baking time in 5-minute increments and check with a thermometer before moving to the uncovered stage.
Rice isn’t fully cooked after the recommended time.
don’t panic! Add ¼ cup of hot liquid (broth or water), re-cover with foil, and bake for an additional 10-15 minutes.
The recipe's own notes say rotisserie chicken cuts the bake time by about 10 minutes, which is worth keeping in mind if reheating or repeating the recipe with pre-cooked chicken.
The recipe's own notes suggest warm pita bread or a cucumber salad on the side.
Frequently asked questions
Can I use pre-cooked rice for this Dump-and-Bake Chicken Tzatziki Casserole?
Yes! Use 3 cups of cooked rice and reduce the liquid by half. Adjust cooking time to 25-30 minutes until the chicken is fully cooked.
Is it possible to make this recipe dairy-free?
Absolutely. Substitute the Greek yogurt with coconut yogurt and omit the feta cheese or use a plant-based alternative.
Can I prepare this casserole in a slow cooker?

Use long-grain rice and don’t overmix after adding liquid. Ensure your oven temperature is accurate with an oven thermometer.
How can I make this spicier?
