Ingredients

The Casserole Base

• 1.5 lbs Boneless, Skinless Chicken Breasts (cut into bite-sized pieces)
• 1 ½ cups Long-Grain White Rice (Jasmine or Basmati work best)
• 2 ¾ cups Chicken Broth
• 2 Tbsp Olive Oil
• 3 cloves Garlic, minced
• 1 tsp Dried Oregano
• 1 tsp Dried Dill
• ½ tsp Salt & ¼ tsp Black Pepper
• 1 Lemon (half sliced into rounds, half juiced)

The Tzatziki Topping

• ½ cup Greek Yogurt (plain)
• ¼ cup Cucumber, grated and squeezed dry
• 1 Tbsp Fresh Dill, chopped
• 1 clove Garlic, minced

Instructions

1. Prep the Oven

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with olive oil or non-stick spray.

2. Dump and Stir

Add the uncooked rice, chicken broth, olive oil, lemon juice, garlic, oregano, dill, salt, and pepper directly into the baking dish. Stir well to ensure the spices are evenly distributed.

3. Add the Chicken

Nestle the raw chicken pieces into the rice and broth mixture. Place the lemon slices on top of the chicken for extra flavor and a beautiful presentation.

4. Cover and Bake

Cover the dish tightly with aluminum foil. This is the most important step to ensure the rice steams perfectly. Bake for 35–45 minutes, or until the liquid is absorbed and the chicken is cooked through.

5. The Tzatziki Finish

While the casserole bakes, stir together the Greek yogurt, cucumber, fresh dill, and garlic in a small bowl.

6. Serve

Remove the foil and fluff the rice with a fork. Top each serving with a generous dollop of the cool tzatziki. Garnish with fresh parsley or Kalamata olives if desired.

Expert Tips for Success

• Rinse the Rice: Always rinse your white rice in a fine-mesh sieve until the water runs clear. This removes excess starch and prevents the casserole from becoming “gummy.”
• Tight Foil Seal: If steam escapes, your rice will stay hard. Ensure the foil is crimped tightly around the edges of your baking dish.
• Squeeze the Cucumber: When making the tzatziki, use a paper towel to squeeze every drop of moisture out of the grated cucumber. This keeps your sauce thick and creamy rather than watery.
• Let it Rest: Let the casserole sit, covered, for 5 minutes after taking it out of the oven. This allows the remaining moisture to finish hydrating the rice grains.

Variations

• Veggie Loaded: Add ½ cup of halved cherry tomatoes and ¼ cup of sliced Kalamata olives to the dish before baking.
• Feta Twist: Sprinkle ½ cup of crumbled Feta cheese over the top of the casserole for the last 5 minutes of baking.
• Brown Rice Version: If using brown rice, increase the broth to 3 ¼ cups and the bake time to 65–75 minutes.
• Spinach Addition: Stir in two handfuls of baby spinach immediately after taking the dish out of the oven; the residual heat will wilt it perfectly.

FAQ: Dump and Bake Chicken Tzatziki Casserole

Q: Can I use chicken thighs? A: Yes. Boneless, skinless chicken thighs are excellent in this recipe as they stay very juicy during the baking process.

Q: My rice is still crunchy—what happened? A: This usually means the foil wasn’t sealed tight enough or the oven temperature is slightly off. Add ¼ cup of hot broth, reseal tightly, and bake for another 10 minutes.

Q: Can I make this ahead of time? A: You can prep the tzatziki a day in advance. However, the “dump and bake” components should be combined right before baking so the rice doesn’t get mushy.

Q: How do I store leftovers? A: Store in an airtight container in the fridge for up to 3 days. Reheat the chicken and rice, but add the cold tzatziki after reheating for the best flavor.
