What is Dump and Bake Chicken Tzatziki Casserole?

Dump and Bake Chicken Tzatziki Casserole is a dreamy blend of Greek flavors wrapped up in a “no-fuss, no-muss” kind of method. Think tender cooked chicken, fluffy rice, fresh veggies, and creamy tzatziki all baked into one warm and satisfying casserole. The term “dump and bake” refers to its magical simplicity: no stovetop prep, no separate mixing bowls—just a single baking dish, a little layering, and straight into the oven it goes.

If you’re familiar with traditional Mediterranean ingredients, you’ll recognize the cool cucumbers, juicy cherry tomatoes, red onion, and oregano here—but with a distinctly American casserole spin. It’s not your grandma’s lasagna, but it’s just as comforting and possibly way easier. It gives “busy weeknight hero” while still tasting like something you’d find in a cozy taverna on a Greek island. And don’t worry if you’re not typically a tzatziki lover—when it bakes, it transforms into a mellow, creamy sauce that hugs every grain of rice and bite of chicken. Basically, it’s dinner goals.

Ingredients Needed to Make Dump and Bake Chicken Tzatziki Casserole

Here’s what you’ll need to bring this dreamy, one-dish dinner to life:

• 2 cups cooked chicken breast, diced or shredded (rotisserie chicken works great)
• 1 cup uncooked long-grain rice (don’t substitute with quick-cooking rice)
• 2 cups chicken broth (low-sodium if you’re watching salt)
• 1 cup tzatziki sauce (store-bought or homemade)
• 1 cup diced cucumber (peeled if you want it extra soft)
• 1 cup cherry tomatoes, halved
• 1 small red onion, diced
• 1 cup shredded mozzarella cheese
• 1 teaspoon dried oregano
• 1 teaspoon garlic powder
• ½ teaspoon salt
• ¼ teaspoon black pepper
• Fresh parsley, for garnish (optional but adds a lovely pop)

Instructions to Make Dump and Bake Chicken Tzatziki Casserole – Step by Step

Step 1: Preheat and Prep the Dish

Start your Dump and Bake Chicken Tzatziki Casserole by preheating the oven to 375°F (190°C). That way, it’s ready to go once everything is assembled. While the oven’s heating, grab a 9×13-inch baking dish and give it a quick spray or a light rub of oil to prevent sticking. You don’t need to line it—this is about simplicity, not extra parchment paper origami.

Step 2: Mix the Base Flavors Together

Now comes the “dump” part—so satisfying, right? Into your greased baking dish, pour in the uncooked long-grain rice, chicken broth, tzatziki sauce, garlic powder, oregano, salt, and black pepper. Stir it all up right in the dish until it’s well combined. This creamy base is the secret sauce of the casserole, infusing everything with herby, garlicky Mediterranean vibes as it bakes.

Step 3: Add the Chicken and Fresh Veggies

Next, toss in your cooked chicken, diced cucumber, halved cherry tomatoes, and chopped red onion. Stir again until everything’s evenly spread and coated in that lovely tzatziki broth blend. Don’t worry if it looks a little soupy at this point—the rice will absorb the liquid while baking. It’s one of those magical transformations that happens in the oven while you sip tea or scroll Pinterest.

Step 4: Cover and Bake

Cover the baking dish tightly with foil and slide it into your preheated oven. Bake for 35–40 minutes. This gives the rice time to soak up all that flavorful liquid and become perfectly tender. Around the 35-minute mark, carefully lift the foil (watch out for steam!) and check the rice for doneness. If it’s still a little chewy, give it another 5 minutes.

Step 5: Add Cheese and Bake Again

Once the rice is tender and most of the liquid is absorbed, remove the foil and sprinkle the shredded mozzarella cheese evenly over the top. Pop it back in the oven, uncovered, for another 5–7 minutes. The cheese will melt into a golden, bubbly layer that ties everything together. If you’re feeling fancy, broil it for the last 1–2 minutes to get those crispy edges. Just don’t walk away—broilers move fast.

Step 6: Rest, Garnish, and Serve

When it’s done, take it out and let it sit for 5 minutes. This gives the casserole a moment to settle and makes it easier to scoop. Sprinkle with chopped fresh parsley if you have it—it adds a burst of color and freshness that’s so worth the extra 10 seconds. Serve it up hot, and enjoy how cozy and complete it feels. Bonus: leftovers are even better the next day.

What to Serve with Dump and Bake Chicken Tzatziki Casserole

While Dump and Bake Chicken Tzatziki Casserole is a full meal on its own, you can easily round it out with a few simple sides. A fresh Greek salad or Winter Farro and Kale Salad brings brightness and texture to the plate. Warm pita bread is another great addition—it’s perfect for scooping up the creamy bits of rice and tzatziki left on the plate. If you’re in the mood for a light soup, try pairing it with this Lemon Chicken Couscous Soup. And don’t forget dessert! This White Chocolate Raspberry Tiramisu adds a sweet, dreamy finish.

Key Tips for Making Dump and Bake Chicken Tzatziki Casserole

1. Use real long-grain rice—quick or instant varieties won’t work the same way and could turn mushy or dry. 2. Pre-cooked chicken is key—shredded rotisserie chicken is a lifesaver and adds flavor without extra steps. 3. Don’t skip the foil in the first bake—this traps the steam so the rice cooks evenly. 4. Feel free to customize—swap mozzarella for feta if you want a saltier, more Greek-inspired twist. 5. Let it rest—those 5 minutes after baking make a big difference for texture and scoopability. 6. Want a little heat? Toss in some red pepper flakes or chopped kalamata olives for a grown-up flair. 7. Make it gluten-free—double check your broth and tzatziki to keep everything celiac-friendly.

Storage and Reheating Tips for Dump and Bake Chicken Tzatziki Casserole

Leftovers? You’re in luck. This casserole stores beautifully. Let it cool completely before transferring to an airtight container. You can refrigerate it for up to 4 days. For reheating, you can pop a single serving in the microwave for about 90 seconds, stirring halfway through. Want that fresh-from-the-oven vibe? Reheat it in the oven at 350°F for 10–15 minutes, covered with foil so it doesn’t dry out. If you made a big batch and want to freeze it, go for it—but do it before adding the cheese. Freeze in a tightly sealed container for up to 2 months. Thaw overnight in the fridge and add cheese right before reheating. It’s the kind of dish that somehow tastes better the next day—like all the flavors had a little sleepover.

FAQs

Can I use brown rice instead of white? Sure, but you’ll need to increase the bake time by 15–20 minutes and possibly add more broth. Brown rice takes longer and absorbs more liquid.

What if I don’t have tzatziki sauce? You can mix plain Greek yogurt with a bit of lemon juice, garlic, and dill for a quick sub. Not quite the same, but close enough for a pinch.

Is this casserole freezer-friendly? Yes! Freeze before baking for best texture, especially if you’re planning to reheat the whole dish later.

Can I make it vegetarian? Absolutely. Just skip the chicken and sub in chickpeas or a plant-based protein like lentils or tofu.

Does it work for picky eaters? Surprisingly, yes. The flavors are mellow and comforting, and everything gets all mixed together—which picky eaters sometimes prefer!
