Tips for Success
- Always squeeze the grated cucumber thoroughly using a paper towel to prevent excess liquid from watering down your sauce.
- Use room-temperature chicken to ensure the dish cooks evenly throughout the baking process.
- Let the casserole rest for five minutes after removing it from the oven to allow the creamy sauce to set properly.
Variations & Substitutions
- Add a sprinkle of red pepper flakes if you enjoy a subtle, warming heat.
- Swap the mozzarella for crumbled feta cheese to lean into a more traditional Mediterranean flavor profile.
- Use fresh herbs like parsley or mint instead of dried dill for a brighter, garden-fresh finish.
Serving Suggestions
- Serve alongside a crisp green salad tossed in a simple lemon vinaigrette.
- Pair with roasted cherry tomatoes for a burst of sweetness that complements the tangy yogurt.
- Enjoy with a chilled cucumber-infused sparkling water for a refreshing, non-alcoholic drink pairing.
Health Benefits
- High in lean protein, which supports muscle maintenance and keeps you satiated longer.
- Rich in probiotics from the Greek yogurt, supporting healthy digestion.
- Low-carbohydrate profile makes this an ideal choice for stable blood sugar management.
Storage & Reheating
- Store leftovers in an airtight container in the refrigerator for up to three days.
- Reheat gently in the oven or microwave, adding a splash of water if the sauce appears too thick.
- Avoid freezing, as the creamy yogurt sauce may separate and lose its smooth texture upon thawing.

Frequently Asked Questions
Can I use chicken breast instead of thighs?
Yes, chicken breasts work perfectly in this recipe. Just be careful not to overcook them, as they dry out faster than thighs.

Keep the oven temperature at 375°F. Using full-fat Greek yogurt also helps maintain a stable, creamy consistency during the baking process.
Is it possible to double this recipe?
Absolutely. Use a larger baking dish to maintain a single layer of chicken and add about five minutes to the total baking time.
