Step‑by‑Step Instructions for Chicken Tzatziki Casserole
Step 1: Preheat Your Oven
Start by preheating your oven to 375°F (190°C). This crucial step ensures your Chicken Tzatziki Casserole bakes evenly. While the oven heats up, grab a 9×13-inch baking dish and lightly grease it with cooking spray or olive oil to prevent sticking. This sets up a perfect base for your delicious casserole.
Step 2: Prepare the Rice Base
Spread the uncooked white rice evenly across the bottom of the prepared baking dish. Make sure the rice forms a uniform layer as it will absorb all the delightful flavors during baking. This is the foundation of your Chicken Tzatziki Casserole, providing a hearty texture that complements the other ingredients.
Step 3: Add Chicken Broth
Pour chicken broth over the rice, ensuring it fully submerges the grains. This step not only hydrates the rice but also infuses it with rich flavor as it cooks. Watch as the broth seeps into the rice, creating an enticing aromatic base that will soon become the heart of your casserole.
Step 4: Layer the Chicken
Distribute your cooked chicken evenly over the rice layer. Whether shredded or diced, the chicken provides the necessary protein and enhances the dish’s overall heartiness. This step is essential because the chicken will meld beautifully with the other fresh ingredients on top, creating a perfect blend of flavors.
Step 5: Scatter Fresh Vegetables
Next, scatter chopped cucumber, red onion, grape tomatoes, and Kalamata olives across the chicken layer. These vibrant components not only add a refreshing crunch and savory tang but also bring cheerful color to your Chicken Tzatziki Casserole. Make sure they are evenly dispersed for maximum flavor in every bite.
Step 6: Mix the Sauce
In a bowl, mix the Greek-style tzatziki sauce with garlic powder, dried oregano, salt, and pepper. This will create a creamy, flavorful topping for your casserole. Spread this mixture evenly over the entire layered ensemble in your baking dish, ensuring every ingredient is enveloped in this delightful sauce.
Step 7: Top with Feta Cheese
Crumbled feta cheese comes next! Generously sprinkle the feta over the tzatziki sauce, allowing its tangy creaminess to balance the other flavors. As it bakes, the cheese will melt and create a lovely golden-brown crust on top, adding both texture and irresistible flavor to your Chicken Tzatziki Casserole.
Step 8: Bake Covered
Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 45 minutes, allowing the flavors to meld and the rice to become tender. The foil helps keep moisture in, ensuring a succulent casserole while the enticing aromas fill your kitchen.
Step 9: Bake Uncovered
After 45 minutes, remove the foil and return the casserole to the oven. Bake uncovered for an additional 10 minutes until the feta cheese turns golden and the top is bubbly. This final phase is key for achieving that perfect, inviting presentation for your Chicken Tzatziki Casserole.
Step 10: Cool and Garnish
Once baked, remove the casserole from the oven and let it cool for a few minutes. This rest time allows the flavors to settle. Lastly, garnish with fresh chopped parsley before serving. This vibrant touch not only brightens up the dish but adds a fresh flavor to your comforting Chicken Tzatziki Casserole.

Chicken Tzatziki Casserole Recipe FAQs
What kind of chicken should I use for the casserole?
Absolutely! You can use either shredded or diced cooked chicken for your Chicken Tzatziki Casserole. This not only adds hearty protein to the dish but also ensures it melds beautifully with the other ingredients. If you’re feeling adventurous, consider using leftover rotisserie chicken; it saves time and infuses additional flavor!
How should I store leftovers?
To keep your Chicken Tzatziki Casserole fresh, store leftovers in an airtight container in the fridge. They will last up to 3 days. Make sure to let it cool completely before sealing to avoid condensation, which can make the casserole soggy. For longer storage, you can freeze it for up to 3 months.
Can I freeze the Chicken Tzatziki Casserole?
Very! To freeze, divide the casserole into individual portions for easier reheating. Wrap each portion tightly in plastic wrap, followed by aluminum foil to keep out air. When you’re ready to enjoy it again, thaw overnight in the fridge and then reheat in the oven at 350°F (175°C) for about 20 minutes or until warmed through.
What should I do if the rice isn’t cooked through?
If you find that the rice hasn’t fully cooked after following the baking times, don’t worry! Simply cover the casserole back up and return it to the oven, checking every 5 minutes until the rice is tender. Adding a splash more chicken broth can help steam the rice and keep the dish moist during this additional cooking.
Are there any dietary considerations with this recipe?
Great question! If you have any allergies or dietary restrictions, consider substituting certain ingredients. For instance, you can use brown rice for more fiber or a dairy-free tzatziki sauce for a dairy-free option. Just be mindful that if you are preparing this for pets, the feta cheese and olives may not be suitable for them, so be happy to serve them a pet-friendly meal instead!
What should I do if I have leftover tzatziki sauce?
I recommend storing any leftover tzatziki sauce in a sealed container in the fridge, where it will stay fresh for 3 to 4 days. It can be a delicious dip for fresh veggies or pita bread, or even a dressing for salads. Don’t let any deliciousness go to waste!
