Common Mistakes to Avoid

1. Not Rinsing the Rice

Skipping this step can lead to excess starch, making the casserole sticky instead of fluffy. Always rinse rice under cold water until the water runs clear.

2. Overcooking the Chicken

Cutting chicken into evenly sized pieces helps ensure it cooks at the same rate. Overcooking can make it dry, so stick to the recommended baking times.

3. Skipping the Foil Cover

Covering the casserole for the first part of baking helps retain moisture and ensures the rice cooks properly. Removing the foil at the end allows the top to develop a slight crisp.

4. Forgetting to Season the Broth

The stock is the foundation of the dish’s flavor. Make sure it is well-seasoned so the rice absorbs a rich, aromatic taste.

5. Using Too Much Liquid

Adding excess broth can result in mushy rice. Stick to the recommended three cups for the right texture.

6. Not Letting the Casserole Rest

Allowing the dish to sit for five minutes after baking helps redistribute moisture, making it easier to serve.

By following these tips, you can ensure your Chicken Tzatziki Casserole turns out flavorful, well-balanced, and perfectly cooked every time.

Storage & Reheating Instructions

How to Store Leftovers
