Ingredients Needed
Chicken - For this Greek chicken recipe I reached for boneless chicken. You will dice up the chicken. If you want to use boneless chicken thighs or tenderloins, go right ahead.
Artichoke Hearts & Roasted Red Peppers - Grab a jar of artichoke hearts and peppers then drain off the liquid. These two ingredients add tons of flavor.
Kalamata olives - Kalamata olives are the perfect compliment to the chicken.
Homemade Dressing - What makes this low-carb casserole stand out, is the homemade dressing. Red wine vinegar, oil, oregano, and more help bring all the flavors of Greek!
How to Make Greek Chicken Casserole
Full measurements and steps to make Greek chicken casserole are in the recipe card below.
Step 1: In a jar work on adding all your ingredient for the homemade dressing in the container. Shake until the dressing is combined.
I love using a mason jar for making dressing, it is quick, easy and great to store as well.
Step 2: Now dice up your boneless chicken and place it in a bag. Add half the dressing and let it marinade. This is important to help the chicken soak up the Greek flavor and help keep the chicken moist.
Step 3: Once the chicken is done marinating, then place in your baking dish. Sprinkle olives, artichoke hearts, and peppers evenly over the chicken. As well as the remaining dressing.
Step 4: Top with mozzarella cheese, and bake the chicken casserole in the oven until the chicken is fully cooked. This takes around 45 minutes.
Dish up this incredible low carb Greek chicken casserole that is so flavorful.
Pair This Low Carb Casserole With
Not sure what to pair with your casserole to make a complete dinner? Here are a few options to consider. Mashed cauliflower would be a nice pairing. Cauliflower rice is another go-to side dish I enjoy. I just leave out the cilantro and lime in this recipe.
A salad would also help a great mix of flavor next to your chicken recipe.

Expert Tips & Variations To Recipe
- Feel free to use bone-in chicken, just adjust the cooking time to make sure the chicken gets fully cooked. Bone-in chicken takes longer.
- The internal temperature of the chicken needs to be 165 degrees internally.
- Consider swapping the mozzarella cheese out with a sprinkle of parmesan for a change, or do no cheese at all.
- You can leave out the zucchini or add it in, I find it pairs nicely and helps make this dish more filling.
- Swap zucchini with some cauliflower rice to make it a rice style dish.
Recipe FAQs
Can I Use Store Bought Dressing Instead of Making Homemade?
Go right ahead and reach for a store bought Greek dressing to use instead of making your own. Just watch the ingredients to make sure it is not high in carbs.
Some dressings can be higher in carbs.
How long should you marinate chicken?
You can marinate this chicken in the Greek dressing for 20 minutes. Now if you want you can marinate it for an hour or two, to help add in even more flavor.
But this is a quick marinade, as you will pour the remaining sauce over the chicken and bake. (Please don't use the marinade in which the chicken was marinating.)
How long can this Greek chicken store for?
If you have leftover casserole it will store for up to three days in the refrigerator. Then just reheat in the microwave, or cover with foil and reheat in the oven.
I love using the leftovers to make a simple grab and go lunch option!

I am fixing to put the Greek Casserole in the oven! Looks delicious! But was the mozzarella cheese supposed to be mixed in the dressing? It was listed with the dressing ingredients. Do I add more cheese? (Of course I didn’t read the entire recipe before I started.)Can’t wait to eat!
Sarah Hardy
No, the cheese goes on top. 🙂 I've corrected it in the recipe card.
Christine
Good flavor but seemed to have way too much liquid. Not sure how mozzarella fit into the Greek theme- feta might have been a better choice. OK, but probably wouldn't make again.
Sarah Hardy
Thank you for your honest review. 🙂
Lisa
Please include the measurement for the artichoke hearts and peppers...I am inside of what size can you are talking about and my store has jars. Thank you.
Deborah
Delicious!!! I had a lot of liquid on the bottom of the casserole and I’m confused as to where it came from. Followed the recipe precisely. Did anyone do anything different to avoid the large amount of liquid???
