What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to create a delicious and satisfying meal. Here’s what you’ll need:

Chicken Breast: Boneless and skinless. Cut into bite-sized chunks for even cooking.
Cucumber: Grated and squeezed to remove excess water (key for making the tzatziki sauce creamy without being watery).
Greek Yogurt: Full-fat is best for a rich, velvety sauce, but feel free to use low-fat if you prefer.
Garlic: Freshly minced for bold flavor.
Lemon Juice: Freshly squeezed for that bright, tangy kick.
Olive Oil: Extra virgin, to add richness and flavor.
Dill: Fresh or dried, but fresh will give the best flavor. This herb ties the dish together beautifully.
Oregano: For that classic Mediterranean taste.
Salt and Pepper: To season the chicken and elevate all the flavors.
Onion: Thinly sliced for a touch of sweetness and texture.
Cherry Tomatoes: Halved for a juicy, tangy bite in every forkful.
Feta Cheese: Crumbled for a salty, creamy topping that’s so irresistible.

Optional substitutions: Swap Greek yogurt with a dairy-free yogurt for a lactose-free option. Use zucchini instead of cucumber for a slightly different twist. You can also opt for chicken thighs if you prefer darker meat—just adjust the cooking time slightly!

Equipment Needed

Casserole Dish: A 9×13-inch dish works perfectly for this recipe.
Mixing Bowls: You’ll need one for the tzatziki sauce and one for tossing the chicken and veggies.
Grater: For shredding the cucumber.
Sharp Knife: Essential for cutting the chicken, onion, and tomatoes evenly.
Cutting Board: A sturdy surface for prepping your ingredients.

Alternative options: If you don’t have a casserole dish, a deep oven-safe skillet can work in a pinch. And for grating the cucumber, a food processor with a grating attachment will save you some time!

Preparation Method

Preheat the oven: Set your oven to 375°F (190°C) and lightly grease your casserole dish with olive oil.
Prep the chicken: Cut the chicken breasts into bite-sized pieces and season generously with salt, pepper, oregano, and a tablespoon of olive oil.
Make the tzatziki sauce: In a mixing bowl, combine the grated and drained cucumber, Greek yogurt, minced garlic, lemon juice, dill, and a pinch of salt. Mix until smooth and creamy, then set aside.
Combine the casserole base: In a large bowl, toss the seasoned chicken pieces with sliced onion and cherry tomatoes. Add half of the tzatziki sauce and mix until everything is evenly coated.
Assemble the casserole: Pour the chicken and veggie mixture into the prepared casserole dish. Spread it out evenly, then dollop the remaining tzatziki sauce on top. Sprinkle with crumbled feta cheese.
Bake: Cover the casserole with foil and bake for 25 minutes. Then, remove the foil and bake for an additional 10-15 minutes, or until the chicken is fully cooked and the top is golden and bubbly.
Serve: Let the casserole cool for 5 minutes before serving. Garnish with fresh dill or extra feta if desired.

Pro tip: If your tzatziki sauce looks too thick after mixing, add a splash of olive oil or water to thin it slightly. And don’t skip draining the cucumber—it makes all the difference!

Cooking Tips & Techniques

Here are a few tips to ensure your Chicken Tzatziki Casserole turns out perfectly every single time:

Don’t skip draining the cucumber: Excess water can make your casserole too runny. Use a clean kitchen towel to squeeze out as much liquid as possible.
Cut chicken evenly: Uniform pieces ensure the chicken cooks evenly. Uneven cuts can lead to some pieces being overcooked while others are underdone.
Use fresh ingredients: Fresh dill, garlic, and lemon juice will give your tzatziki sauce a bright and vibrant flavor.
Don’t rush the baking: Covering the casserole for the first part of baking helps lock in moisture, while uncovering it ensures a beautiful golden finish.
Rest before serving: Let the casserole sit for 5-10 minutes after baking. This helps the flavors meld and makes it easier to serve.

Variations & Adaptations

Want to mix things up? Here are some fun variations:

Low-Carb Option: Skip the cherry tomatoes and add chopped zucchini or cauliflower instead.
Vegetarian Version: Replace the chicken with cubed tofu or chickpeas for a plant-based twist.
Spicy Kick: Add a teaspoon of red chili flakes to the tzatziki sauce for a touch of heat.
Seasonal Additions: Swap cherry tomatoes for roasted butternut squash during fall or fresh asparagus in spring.
Personal Touch: One time, I added sun-dried tomatoes and Kalamata olives to the casserole for extra Mediterranean flair—it was amazing!

Serving & Storage Suggestions

This casserole is best served warm, straight out of the oven. Pair it with a simple green salad or some pita bread for a complete meal. You can also serve it with a side of rice or quinoa if you’re looking for something heartier.

For storage, place leftovers in an airtight container and refrigerate for up to 3 days. To reheat, cover the casserole and bake at 350°F (175°C) for about 10-15 minutes, or microwave individual portions until heated through. If you want to freeze it, make sure it’s cooled completely before wrapping tightly in aluminum foil or placing it in a freezer-safe container. It will keep in the freezer for up to 3 months.
