This Tzatziki Chicken & Rice Casserole is the perfect weeknight dinner. What I love about this Freezer Friendly Casserole is that everything bakes together in one dish. The rice absorbs all the bright lemon, garlic, and herb flavors while the creamy baked feta melts into the casserole, creating a rich and flavorful meal with almost no cleanup.

I've been loving casseroles like this because they're perfect for meal prep and freezing. It has all the fresh flavors of a Greek chicken bowl with tzatziki, but in a cozy baked casserole that's easy enough for a busy weeknight. Just add the fresh toppings after reheating for that cool, creamy tzatziki-inspired finish.

Ingredients for this Chicken & Rice Casserole

Chicken Thighs

Boneless, skinless chicken thighs stay tender and juicy while baking.

Long-Grain White Rice

The rice cooks directly in the flavorful broth, soaking up all the Greek-inspired flavors.

Chicken Broth

Infuses the rice with savory flavor while it cooks.

Feta Cheese

A whole block of feta softens as it bakes, creating a creamy sauce throughout the casserole.

Garlic

Fresh garlic gives the casserole bold Mediterranean flavor.

Lemon Juice & Lemon Zest

Brightens the entire dish and balances the richness of the feta.

Olive Oil

Adds richness and helps the flavors come together.

Fresh Dill

Adds the signature herb flavor that makes this casserole taste like tzatziki.

Spinach

Stirred in at the end for color, nutrition, and freshness.

Substitutions and Variations

Use Chicken Breast

Boneless chicken breasts work well if you prefer leaner meat.

Add More Vegetables

Artichokes or roasted red peppers are delicious additions.

Make It Extra Creamy

Stir in a few tablespoons of plain Greek yogurt after baking.

Use Brown Rice

Brown rice can be used, but it will require additional broth and a longer bake time.

Add Olives

Kalamata olives make a great garnish for extra Mediterranean flavor.

How to make:

Layer everything but the spinach in a casserole dish.

Bake covered in foil.

Uncover and stir in spinach and bake a little more.

Serve with fresh toppings.

Tips and Notes

Use a block of feta rather than crumbled for the creamiest texture.
Make sure the baking dish is tightly covered so the rice cooks properly.
Stirring in the spinach at the end keeps it vibrant and fresh.
Fresh toppings should always be added after reheating if freezing.

Storage and Reheating Instructions

Storage

Store leftovers in an airtight container in the refrigerator for up to 4 days.

Reheating

Microwave individual portions or reheat in a 350°F oven until warmed through.

Tips

Add fresh cucumber, tomatoes, dill, parsley, and tzatziki after reheating for the freshest flavor and texture.

Freezer Instructions

1. Cool completely.
Never freeze hot food. Let it cool completely first (you can even refrigerate it overnight). Before sealing, wipe away any condensation inside the container to help prevent ice crystals from forming.

2. Portion it for real life.
Freeze the amount you'll actually use. If your family won't eat a whole casserole in one night, divide it into smaller portions instead. Smaller portions also thaw much faster.

3. Leave a little room.
Don't fill containers all the way to the top, foods expand slightly as they freeze.

4. Label everything.
Write the recipe name and the date on each container so you know exactly what's waiting in your freezer.

5. Freeze.
I love freezing meals in 2-cup silicone freezer cubes. They're the perfect size for lunches or small dinners, stack beautifully, and thaw much faster than one giant frozen block.

How to Reheat

For best results, transfer your meal to the refrigerator the night before.

If it's still a little frozen in the center, microwave on the Defrost setting in 5-minute intervals until it can be broken apart easily.

Then simply reheat like you would any leftovers:

Bake casseroles in the oven.
Warm soups, pasta, and skillet meals on the stovetop.
Use the microwave for quick meals.
The air fryer works great for foods that should stay crispy.

My favorite freezer rule: Reheat food the same way you originally cooked it whenever possible. It almost always gives you the best texture.

Storage Tip: For the best flavor and texture, enjoy freezer meals within about 3 months.
