Made in one pan and packed full of protein and veggies, this Greek chicken casserole is perfect for a weeknight meal. The combination of chicken, orzo pasta, and cheese ensures it’s a delicious dish the whole family can enjoy.

If you’ve been around here long enough, you’re likely aware that I love a good casserole. Not the old-school back of canned soup casserole, but an easy one-pan recipe that is full of healthy whole foods and packed full of protein, veggies, and healthy fats.
I’ve shared plenty of casserole recipes on my site, and there are lots more to come, so consider this Greek chicken casserole just another delicious and nutritious recipe you can add to your casserole repertoire.

Why You’ll Love It
- Made in One Pan – This dump-and-bake recipe requires minimal prep time and minimal cleanup.
- High in Protein – With 30 grams of protein per serving, this Greek chicken casserole is a high-protein dinner idea.
- Great for Meal Prep – Once cooked, this casserole keeps well in the fridge and freezer making it a great make-ahead meal.

Ingredients + Substitutions
- Chicken – To ensure the casserole is protein-packed. The recipes called for cooked chicken, you can use the meat of skinless chicken breasts or skinless, boneless chicken thighs, or any combination of chicken meat you have on hand.
- Orzo – To add some complex carbohydrates. If you can’t find orzo, you can use another small pasta shape, such as ditalini, or use white rice or quinoa instead.
- Onion and Garlic – To flavor the casserole. I use fresh onion and garlic, but you can use onion powder and garlic powder if needed. See the notes section of the recipe card for details.
- Sundried Tomatoes – To add some veggies. I think sundried tomatoes work best, but sliced cherry tomatoes will also work.
- Spinach – To add some leafy greens and micronutrients. The recipe calls for fresh spinach, but you can use frozen spinach if needed, see the notes section of the recipe card for details.
- Kalamata Olives – To add some healthy fats, although you can omit them if desired.
- Feta – To add some more protein.
- Oregano – To add some Greek flavor. I used dried oregano, but you can swap it for thyme or use fresh oregano if needed, see the notes section of the recipe card for details.
- Lemon – A combination of lemon juice and lemon zest to add some more flavor. I used fresh lemon juice but you can use concentrate and omit the zest if needed.
- Broth – To add flavor and cook the orzo, but you can use chicken stock or water if needed.
- Salt and Pepper – To season the casserole.


Dietary Adaptions
To Make it Gluten-Free: Swap the orzo for gluten-free orzo, white rice, or quinoa. Cauliflower rice cannot be used in this recipe, the ratios will not work.
To Make it Dairy-Free: Use dairy-free feta or omit it completely.


Red’s Nutrition Tip
Not only does adding feta to the casserole add a bit of Greek flavor, but it adds a good boost of protein as feta is one of the highest protein cheeses.

Serving Suggestions
This Greek chicken casserole is a well-balanced meal with protein, carbohydrates, fiber, and plenty of healthy fats. That said, you can adapt the recipe to suit your personal dietary needs, for example:
- To add more protein, add a 1/2 pound of shredded, cooked chicken to the recipe, along with an additional 1 cup of chicken broth.
- To add more vegetables, add 1 cup of diced artichoke hearts, zucchini, or bell peppers, along with an additional 1/4 cup of chicken broth. You can also serve the casserole with a side of green salad with diced cucumber and tomatoes.
- To make it low-fat, omit the olive oil and use low-fat feta cheese.

Can I make it in a slow cooker or crock pot?
Yes! Combine the ingredients as per the instruction in a slow cooker or crock pot, instead of a casserole dish, cover, and cook on high for 2 1/2 to 3 hours or low for 5 to 6 hours, until the liquid is absorbed and the orzo is tender.
Storage + Reheating
To Refrigerate: Once cooled, any leftover Greek chicken casserole can be stored in an airtight container in the fridge for up to 5 days.
To Freeze: To freeze the casserole whole, cover the casserole dish with plastic wrap and aluminum foil, and place it in a freezer-safe bag, and place it in the freezer. To freeze the leftover casserole, transfer the leftovers to an airtight container and place it in the freezer. The casserole can be frozen for up to 3 months.

Oven temp?
400°F 🙂
Easy to make and lots of flavor. I’d use less liquid as mine came out a little soupy.
Loved the flavor and overall product, however it came out soupy vs casserole. I baked it additonal 10 minutes as well and it was still soupy. I will adjust liquid amoutn and/or cook time if I make it again.
Made this for dinner. Loved it and will make it again.
Thank you for sharing, Karen! I’m happy you enjoyed it. 🙂
Delicious! I am usually not one to say so I changed this and that, but necessity made me lol. I thought I had orzo but did not so used rice. And could not find sun dried tomatoes but found sundried tomato and basil pesto so used that. Still turned out delicious! And quick, if one had the oven at the right temperature. Today was not my best effort for cooking lol. But the recipe was super good! In spite of me
Love that, it sounds like a great swap to be honest! I’m happy you enjoyed it. 🙂
This was absolutely delicious! Made exactly like the recipe. This meal explodes with flavor with every bite! Highly recommend.
I’m happy you enjoyed it. 🙂 Thank you for sharing, Donna!
Made this twice – once with orzo and the second with risotto… loved it both times. Orzo was a much smoother dish. Risotto had more texture. 100% recommend.
Love that! Thank you so much for sharing, Kim!
This recipe does not work with gluten-free orzo. I used the Banza brand as a substitute and it turned into a gigantic inedible glob
Brands will vary, sorry to hear that one did not work well.
Before making this casserole, I first read the comments. I reduced the amount of broth to 4 cups. Even that was too soupy. A whole squeezed lemon is too overpowering. Half lemon squeezed would improve the taste.
Im confused about the orzo amount 2 cups uncooked? Or metric 182 grams? But the package of Orzo i have is 340 grams and that is equivalent to 2 cups of uncooked Orzo. Please confirm the amount of uncooked Orzo 340g or 182 g?
The recipe is calling for 2 cups of raw orzo.
This recipe is fantastic! It’s incredibly easy to make and delicious. I used slightly less orzo and broth, and it turned out great. Everyone loved it and asked me to make it again next week. All of your recipes are so tasty and user-friendly! Thanks for the great recipes.
I’m so happy you enjoyed it, Moe, thanks for sharing!
Substitutes for Sun dried tomatoes?
Thank you!
You can use diced tomatoes, another veggie of choice, or just omit them completely. 🙂
Delicious! The only thing I change was I use 3 cups of chicken stock and the juice of half a lemon. It came out perfect.
Thanks for sharing, Marsha!
Hi! This looks absolutely delicious. I’m planning on making for a family member in need. Is this recipe freezer friendly? If so, how would you recommend heating after taking from the freezer?
Thank you!!
Yes, it freeze well. You can freeze it whole or individual portions and reheat it in the oven.
Absolutely fantastic! I made this for a program for 20 adults with disabilities. They helped make it and they ate it all! Nothing was left!
Thanks for sharing, Barbara! I’m so happy to hear it was enjoyed. 🙂
This recipe is DELICIOUS! Like so many of Stephanie’s recipes.
Very easy to make and what I love about it, is it has lots of different flavours and textures all in one dish.
My family LOVES the Greek Chicken Casserole and I have made it a few times, always a huge hit!
Yay! So happy the family enjoys it, thanks for sharing, Sheri!
Regarding the Greek Chicken Casserole: I assume you mean 3 chicken breast halves, not 3 whole breasts, because that would be equivalent to 6 thighs. I think chopping the chicken is better than shredding…more toothsome. I am not a fan of feta cheese, so I used dry Jack instead and it’s fine (not easy to acquire, but worth it). I am so sick of people using sun dried tomatoes…I used 1/2 tab of tomato paste (always have it in refrigerator to us in soups and sauces). I used 1/2 cup cherry tomatoes sliced in half. I sauté the chicken in a pan with olive oil and then slice and chop to add to casserole. I think adding 1/2 cup of red, orange, or yellow chopped peppers is also a good addition.
Cool so you made an entirely different recipe! Glad you liked it.
These recipes are amazing
Ty so much
Doing an amazing job!
Loved the flavor, but I think too much liquid orzo was too soft. Gonna try recipe again, but with 4 cups liquid vs 5
This recipe was soooo delicious! What a fantastic combination of flavors.
