Step‑by‑Step Instructions for Dump-and-Bake Chicken Tzatziki Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven warms up, grab a 9×13-inch baking dish and lightly grease it with cooking spray or a drizzle of olive oil. This will ensure that your Dump-and-Bake Chicken Tzatziki Casserole slides out easily once baked.
Step 2: Prepare the Rice Base
Spread uncooked white rice evenly across the bottom of the greased baking dish. Make sure the rice is distributed evenly to ensure it cooks uniformly. The rice will serve as the hearty base for your casserole, soaking up all the delicious flavors as it bakes.
Step 3: Add Chicken Broth
Pour the chicken broth over the rice, ensuring that the grains are fully submerged. The broth will provide moisture and enhance the overall flavor of your casserole. You should hear a gentle slosh as the liquid mixes with the rice, setting the stage for your tasty Dump-and-Bake Chicken Tzatziki Casserole.
Step 4: Layer the Chicken
Next, evenly layer the cooked chicken pieces over the rice and broth mixture. Whether you’re using leftover chicken or rotisserie, make sure to break it into bite-sized pieces for easy eating. The chicken will meld beautifully with the rice as it cooks, creating a flavorful combination.
Step 5: Add Fresh Vegetables
Distribute the chopped cucumbers, sliced red onion, grape tomatoes, and Kalamata olives evenly over the chicken. The vibrant colors of these vegetables will add freshness and visual appeal to your casserole. Don’t be shy! Sprinkle them generously for a beautiful presentation.
Step 6: Mix the Tzatziki Sauce
In a separate bowl, mix the tzatziki sauce with garlic powder, dried oregano, and a sprinkle of salt and pepper to taste. Stir until all ingredients are well combined, then spread this creamy mixture evenly over the layers in your baking dish. This will infuse a lovely tanginess to your Dump-and-Bake Chicken Tzatziki Casserole.
Step 7: Sprinkle with Feta
Now it’s time to sprinkle crumbled feta cheese generously over the top of the casserole. This salty and tangy addition will melt delightfully during baking, adding depth of flavor to the dish. Ensure an even layer of feta so it becomes golden and bubbly as it bakes.
Step 8: Cover and Bake
Cover the baking dish tightly with aluminum foil to trap moisture, which will help cook the rice evenly. Place it in the preheated oven and bake for 45 minutes. At this stage, the casserole will start to meld together, with the aromas filling your kitchen.
Step 9: Remove Foil and Finish Baking
After 45 minutes, carefully remove the foil to allow the top to crisp up. Return the casserole to the oven and bake for an additional 10 minutes, or until the feta cheese turns golden and slightly crispy. Your Dump-and-Bake Chicken Tzatziki Casserole will now be beautifully baked and ready to be enjoyed.
Step 10: Let it Rest and Garnish
Once baking is complete, take the casserole out of the oven and let it rest for about 5 minutes. This resting period allows the flavors to meld. Before serving, garnish with fresh parsley for a touch of color and added freshness, enhancing the overall presentation of your hearty meal.

Dump-and-Bake Chicken Tzatziki Casserole Recipe FAQs
What type of rice is best for this casserole?
I recommend using uncooked white rice for this Dump-and-Bake Chicken Tzatziki Casserole. It will absorb the flavors of the broth perfectly and provide a tender base. Brown rice can be used, but it will require additional cooking time and more broth.
How should I store leftovers?
After you’ve savored your meal, store any leftovers in an airtight container in the refrigerator for up to 3 days. This will keep your casserole fresh and delicious. When reheating, cover it with foil and warm it in the oven at 350°F (175°C) for about 15-20 minutes, or until heated through.
Can I freeze this casserole?
Unfortunately, it's not recommended to freeze the Dump-and-Bake Chicken Tzatziki Casserole due to the dairy content in the tzatziki sauce, which can change texture upon thawing. However, you can prepare it ahead of time, refrigerate it for up to 24 hours, and bake it when you’re ready to enjoy.
What if my rice isn't cooked through after baking?
If you find the rice undercooked, it may not have absorbed enough liquid. Ensure the rice is fully submerged in the chicken broth before baking. If it's still crunchy after baking, add a bit more broth, cover it with foil, and bake for an additional 5-10 minutes.
Are there allergy considerations with this recipe?
Yes, please be mindful of any allergies, particularly to dairy, as the tzatziki sauce and feta cheese contain milk. You can substitute with dairy-free alternatives if needed. Additionally, check for olive and tomato allergies—adjust the ingredient list to suit your family's dietary needs.
