I’ll never forget the night I first made chicken tzatziki casserole. I was scrambling to feed my family after a long day, staring at leftover rice, some chicken breasts, and a half-eaten container of tzatziki.
I just threw everything into a baking dish, scattered cheese on top, and hoped for the best. When I pulled that bubbling pan from the oven, I knew I’d stumbled onto something special.
This dump-and-bake chicken tzatziki casserole brings together tender chicken, creamy tzatziki sauce, fluffy rice, and melted mozzarella in one pan. You just season the chicken, layer everything in a baking dish, and let your oven do its thing.
The tangy tzatziki keeps the chicken moist. The cheese turns golden and bubbly, and suddenly everyone’s reaching for seconds.
You’ll see why this recipe’s my go-to weeknight meal. I’ll walk you through the steps and share a few mistakes I made so you can avoid them.
You can tweak this casserole any way you like. Whether you’re new to Mediterranean cooking or just want a dinner that doesn’t leave a pile of dishes, this recipe comes through.

How To Make Dump and Bake Chicken Tzatziki Casserole
You’ll pull this casserole together with a few simple steps. The hands-on time stays under 15 minutes.
Mix chicken with seasonings, layer everything in the dish, and let the oven do its thing. The rice soaks up the juices and the cheese melts into a golden blanket.
Ingredients
Start with 1 pound of chicken breast, cut into bite-sized pieces. It cooks faster and makes serving easier.
Toss the chicken with 2 tablespoons olive oil, 2 minced garlic cloves, 1 teaspoon dried oregano, 1/2 teaspoon salt, and 1/4 teaspoon black pepper.
For the base, use 1 cup of cooked rice. I like to cook my rice in low-sodium chicken broth for extra flavor.
Spread 1 cup of tzatziki sauce over the chicken. Store-bought tzatziki works when you’re short on time, but homemade tzatziki (Greek yogurt, grated cucumber, garlic, lemon juice, dill) gives you more control.
Top it off with 1 cup shredded mozzarella cheese. Finish with 1/2 cup chopped cucumber, 1/4 cup sliced red onion, and 1 tablespoon chopped fresh dill.
Instruments
You’ll need a 9×13-inch baking dish for the layers. A large mixing bowl helps toss the chicken evenly with the seasonings.
Grab aluminum foil to cover the dish at first. It keeps the chicken moist and helps the rice cook through.
An instant-read thermometer is handy to check doneness. Aim for 165°F in the thickest chicken piece.
Step-by-Step Instruction for Dump and Bake Chicken Tzatziki Casserole
Step 1:
Preheat your oven to 375°F. Toss the chicken pieces in a large bowl with olive oil, garlic, oregano, salt, and pepper until every piece gets coated.
Step 2:
Spread the cooked rice across your baking dish in an even layer. Add the seasoned chicken on top of the rice and spread it out.
Step 3:
Spoon the tzatziki sauce over the chicken and use the back of the spoon to cover all the meat. Sprinkle mozzarella cheese over the tzatziki.
Step 4:
Scatter the chopped cucumber, red onion, and fresh dill on top. Cover the dish tightly with foil and bake for 25 minutes.
Step 5:
Remove the foil and bake for another 10 minutes. The cheese should bubble and turn golden in spots.
Step 6:
Check that the chicken hits 165°F before pulling it out. Let the casserole rest for 5 minutes so everything settles.
Step 7:
Cleanup’s a breeze since it all cooks in one dish.
Tips & Tricks and My Mistake
Use the right rice. Long-grain white rice works best. I once tried instant rice, and it turned to mush in no time.
Check your broth level halfway through. If the rice looks dry at the 20-minute mark, splash in a bit more broth. Ovens can be unpredictable, and this little step saves dinner.
Let it rest before serving. I used to scoop it right out of the oven and it fell apart. Five minutes makes a difference—trust me.
Serve with warm pita bread on the side. Tearing off pieces and scooping up the creamy chicken and rice just feels right.
Top with pickled red onions for extra tang. The pop of color and acidity perks up the whole plate.
Don’t skip the foil cover. I forgot once and ended up with dry chicken and undercooked rice. The foil really matters.
Make extra tzatziki sauce. You’ll want more for drizzling at the table. I always do.
Nutritional Value
This chicken tzatziki with rice casserole packs balanced nutrition into every serving. Each portion sits at about 360 calories, so you get a meal that’s filling but not heavy.
Chicken brings close to 30 grams of protein per serving. That’ll keep you satisfied and gives your muscles some love after a long day.
The rice base offers complex carbs for energy. You’ll pick up around 28 grams of carbs, which should keep you going through the evening.
Here’s what else you get in each serving:
- Fat: About 14 grams total, mostly from olive oil and mozzarella cheese.
- Saturated Fat: Roughly 5 grams, thanks to the cheese.
- Fiber: 1-2 grams from the rice and veggies.
- Sodium: Around 450-500 milligrams, though your tzatziki brand can shift that a bit.
- Calcium: Solid amounts from the cheese and the yogurt in tzatziki.
- Iron: Some, coming from the chicken and rice.
Tzatziki sauce brings in probiotics from yogurt, which is great for your gut. Cucumber and red onion add a few vitamins and minerals, but not many extra calories.
Want to bump up the nutrition? Swap white rice for brown rice or quinoa. You’ll get more fiber—maybe 3-4 grams per serving—and a bonus of B vitamins.
Fresh dill and garlic? They add antioxidants. Olive oil sneaks in healthy fats to help your body soak up those veggie vitamins.
Watching sodium? Go for low-sodium tzatziki and cut back on extra salt. If you’re counting calories, try part-skim mozzarella instead of the regular stuff.
