Ingredients for Dump and Bake Chicken Tzatziki Casserole
Using full-fat Greek yogurt helps create a thick and creamy tzatziki sauce that holds up beautifully during baking. Be sure to remove as much moisture as possible from the grated cucumber to prevent excess liquid in the casserole.
- 1½ pounds boneless, skinless chicken breasts, cut into bite-sized pieces
- 1 cup plain Greek yogurt
- ½ cup grated cucumber, squeezed dry
- 2 garlic cloves, finely minced
- 1 tablespoon fresh lemon juice
- 1 teaspoon dried dill
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 1 cup crumbled feta cheese
- 1 cup shredded mozzarella cheese
- ½ cup chopped red onion
- ½ cup sliced Kalamata olives
- ½ cup chopped tomatoes, drained if needed
Step-by-Step Instructions
For the best texture, prepare the cucumber first and allow it to drain while you gather the remaining ingredients.
Step 1
Preheat your oven to 375°F (190°C) and lightly coat a 9×13-inch baking dish with cooking spray or a small amount of olive oil. Cut the chicken into evenly sized pieces so everything cooks at the same rate and stays tender throughout baking.
Step 2
In a large mixing bowl, combine the Greek yogurt, grated cucumber, garlic, lemon juice, dill, salt, and black pepper. Stir until the mixture becomes smooth and creamy. The sauce should be thick enough to coat the chicken while remaining easy to mix.
Step 3
Add the chicken pieces to the bowl and toss well until every piece is completely covered with the tzatziki mixture. Proper coating ensures the chicken stays juicy and absorbs all the Mediterranean flavors while baking.
Step 4
Transfer the chicken mixture into the prepared baking dish and spread it evenly. Sprinkle the red onion, olives, tomatoes, feta cheese, and mozzarella cheese over the top. Cover the dish tightly with aluminum foil.
Step 5
Bake for 25 minutes with the foil on. Remove the foil and continue baking for another 10 to 15 minutes, or until the chicken is fully cooked and the cheese becomes bubbly and lightly golden. Allow the casserole to rest for about 5 minutes before serving so the sauce can thicken slightly.
What to Serve with Dump and Bake Chicken Tzatziki Casserole
This casserole pairs wonderfully with a variety of Mediterranean-inspired side dishes.
Quinoa or Brown Rice
A serving of quinoa or brown rice helps soak up the creamy tzatziki sauce while adding extra fiber and texture to the meal.
Greek Salad
Fresh lettuce, cucumbers, tomatoes, and a light lemon dressing provide a refreshing contrast to the rich casserole.
Roasted Vegetables
Roasted zucchini, bell peppers, and eggplant complement the Mediterranean flavors while adding color and nutrition to your plate.
Warm Pita Bread
Soft pita bread is perfect for scooping up the creamy sauce and makes the meal even more satisfying.
Cucumber Tomato Salad
A simple salad made with cucumbers, tomatoes, onions, and herbs adds freshness and balances the richness of the cheese.
Lemon Rice
Lightly seasoned lemon rice brings additional Greek-inspired flavor and works beautifully alongside the casserole.
Storage & Serving Tips
Store leftover casserole in an airtight container in the refrigerator for up to four days. As the ingredients sit together, the flavors continue to develop, making leftovers especially delicious.
To reheat, warm individual servings in the microwave for 1 to 2 minutes. For larger portions, cover the baking dish with foil and heat in a 350°F oven until warmed through. A squeeze of fresh lemon juice before serving helps refresh the flavors.
This casserole can be enjoyed in several ways. Serve it over rice, quinoa, or cauliflower rice for a lighter option. It also works well inside pita bread or as part of a Mediterranean-style bowl. Garnishing with fresh dill and a spoonful of Greek yogurt adds extra flavor and presentation.
For meal prep, assemble the casserole up to 24 hours in advance and refrigerate until ready to bake. If baking directly from the refrigerator, add a few extra minutes to the cooking time.
To freeze, prepare the casserole before baking and wrap it tightly. Freeze for up to three months. Thaw overnight in the refrigerator before baking according to the recipe instructions.
