Instructions

Prepare the Chicken Marinade: In a medium bowl, whisk together the olive oil, garlic powder, oregano, lemon juice, salt, and pepper. Pour the marinade into a freezer bag.
Marinate the Chicken: Add the boneless skinless chicken breasts to the freezer bag with the marinade. Seal the bag, removing any excess air, and massage the marinade into the chicken. Refrigerate for at least 30 minutes, or up to 4 hours. The longer the chicken marinates, the more flavorful it will be!
Make the Tzatziki Sauce Base: In a small bowl, combine the minced garlic, olive oil, vinegar, salt, and pepper. Set aside.
Strain the Greek Yogurt: Place the Greek yogurt in a cheesecloth-lined sieve or strainer over a bowl. Allow it to strain for at least 15 minutes to remove excess liquid, creating a thicker consistency. This step is important for achieving the right texture in the tzatziki.
Combine Tzatziki Ingredients: In a separate, larger bowl, combine the strained Greek yogurt and Hidden Valley® Original Ranch® Dressing. Mix well until smooth. Stir in the feta cheese.
Incorporate Garlic Mixture: Add the olive oil and garlic mixture to the yogurt and ranch dressing mixture. Stir gently to combine.
Add Cucumber: Finally, fold in the diced cucumber into the tzatziki sauce. Set the tzatziki sauce aside.
Preheat the Oven: Preheat your oven to 425 degrees Fahrenheit (220 degrees Celsius).
Bake the Chicken: Remove the marinated chicken from the freezer bag and place it on a baking sheet lined with parchment paper or foil. Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through and reaches an internal temperature of 165 degrees Fahrenheit (74 degrees Celsius). To ensure even cooking, consider using a meat thermometer.
Prepare the Casserole: Once the chicken is cooked, remove it from the oven and let it cool slightly. Cut the chicken into bite-sized cubes. Transfer the cubed chicken to a casserole pan.
Combine Chicken, Tzatziki and Spinach: Add the tzatziki sauce to the casserole pan with the chicken. Mix well to ensure the chicken is thoroughly coated in the sauce. Stir in the spinach.
Cover and Bake: Cover the casserole pan tightly with aluminum foil and bake in the preheated oven for 15 minutes.
Add Topping: Remove the casserole from the oven and carefully remove the aluminum foil. Sprinkle the crumbled pita chips evenly over the top of the casserole. Then, sprinkle on the feta cheese, garlic powder, and parmesan cheese.
Bake Again: Return the casserole to the oven and bake, uncovered, for an additional 5 minutes, or until the topping is golden brown and crispy. Watch carefully to prevent burning.
Rest and Serve: Remove the casserole from the oven and let it sit for 5-10 minutes before serving. This allows the flavors to meld together and the casserole to cool slightly.

Expert Tips & Tricks

Strain the Yogurt: Don’t skip straining the Greek yogurt! It’s key for a thick, creamy tzatziki that won’t make your casserole watery. If you don’t have cheesecloth, you can use a coffee filter.
Pita Chip Perfection: For the best topping, use slightly stale pita chips. They’ll crisp up beautifully in the oven. If your pita chips are very fresh, you might want to lightly toast them before crumbling.
Make-Ahead Magic: The tzatziki sauce can be made a day ahead and stored in the refrigerator. This actually allows the flavors to develop even further.
Spice it Up: If you like a little heat, add a pinch of red pepper flakes to the marinade or the tzatziki sauce.
Even Cooking: Pound the chicken breasts to an even thickness before marinating. This ensures they cook evenly in the oven.
Doneness Check: Always use a meat thermometer to ensure the chicken is cooked to a safe internal temperature of 165°F (74°C).

Serving & Storage Suggestions

Serve the Ranch Chicken Tzatziki Casserole hot, straight from the oven. Garnish with a sprinkle of fresh dill or a drizzle of olive oil for an extra touch of flavor and visual appeal.

Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat in the oven at 350°F (175°C) until warmed through, or in the microwave. Be aware that the pita chip topping may soften upon reheating. Freezing is not recommended, as the texture of the tzatziki sauce may change upon thawing.

FAQs (Frequently Asked Questions)

Q: Can I use dried herbs instead of fresh oregano in the marinade?
A: Yes, you can substitute 1 teaspoon of dried oregano for the 1 teaspoon of fresh oregano.

Q: Can I marinate the chicken overnight?
A: While a longer marinating time can enhance the flavor, it’s best to limit the marinating time to 4 hours to prevent the chicken from becoming too acidic and affecting the texture.

Q: Can I add other vegetables to the casserole?
A: Yes, you can add other vegetables such as bell peppers, zucchini, or onions to the casserole for added flavor and nutrients. Sauté them lightly before adding to the casserole.

Q: The pita chips are burning before the casserole is heated through. What can I do?
A: If the pita chips are browning too quickly, tent the casserole loosely with foil during the final baking stage. This will protect the topping while allowing the casserole to heat through.

Q: Can I use pre-made tzatziki sauce to save time?
A: While you can use pre-made tzatziki sauce, the homemade version is much fresher and more flavorful. If you do use pre-made, be sure to choose a high-quality brand.
