I love slow cooker meals so much, I sometimes wonder if I should be a spokesperson for some massive slow cooker producer. I mean seriously, do you know how much I use this kitchen appliance?? Let’s just say it’s a lot. A LOT. It’s not just that it’s so convenient to toss everything in a pot, cover, and come back a few hours later to a whole meal ready to go. It’s also that I love the way slow cooking meals can bring out more flavor in the dish. Like in this mediterranean chicken dish. All those flavors melding together for a while in the slow cooker makes them ten times better.

But let’s talk about a couple of ingredients here. First of all the olives. I’ll preface this by saying that I rarely use regular black olives in my cooking because I just don’t care for them. But kalamata olives? Those are my jam. I adore the briny, salty taste of kalamata olives. If you haven’t tried them, this is your chance to fall in love with these little black beauties.

The other ingredient you might not have a pre-existing relationship with is capers. They too are briny and salty and I can’t get enough of them, particularly in this dish. They’re those little green pea-looking things you see throughout this dish ^^^.  They aren’t expensive and they add a lot to this chicken dish. Together with those kalamata olives, onions, and roasted red peppers… there’s some serious flavor happening here. Not to mention aromas. Your home will smell like a little slice of Southern Europe when you make this dish and that is a very very good thing.

I don’t have a slow cooker—-Can I bake the chicken at a low temperature??? If so what temp and how long please?

I just bought the ingredients to test out this recipe on my family for dinner tonight 🙂

    This was super easy to make, but for some reason the chicken turned out a little dry. I was surprised since being cooked in a slow cooker I was expecting it to be very moist. The flavours were good though.

      Which one did you use? Because chicken breast is notoriously dry. If you use chicken thighs it will be moister.

        If cooked correctly, chicken breasts are never dry. The slow cooker may need a bit of liquid. A bit of broth should help.

This looks so good. Definitely trying soon!

I made this tonight and it was so AWESOME! My guests said it was like a gourmet meal in a restaurant! Served it with garlic Parmesan potatoes and nothing was left!!! Not even a caper!!!

its a relish and food cant wait to be consumed… i love the summarization of the recipe…BTW, i made a price research for slow cooker, and one of the selection is BETTER CHEF $55., at .. i think their price is cheaper and reasonable..others are quite expensive after checking it wwith other site..
what are your thoughts about this?

I just cooked this recipe but I skipped the searing part of step one and it still came out fantastic and quite juicy! Goes well with garlic mashed potatoes.

Looking at the comments, especially RLSCM, what would happen if I cook the chicken for only 3 hours???
Would love to try this.

It’s in the crockpot right now and smells amazing. Serving with cous cous

sounds very good and i will be trying it, but you didn’t list the lemon juice and amount in you ingredients. how much? thanks

    The juice of 1 lemon, about 2 tablespoons 🙂

Everyone liked this. Although I left out the kalamata olives because my family just doesn’t like olives, the dish was still very flavorful. I used four very large boneless, skinless chicken breasts. I cooked in my Crockpot for 2 hours low and 2 hours high. I would have been able to cook all on low except I thought the onions weren’t cooking in a timely manner. Next time I will sauté the onions while I brown the chicken. The chicken was moist and tender. I have a 6 quart Crockpot brand slow cooker for reference. Good recipe, thanks!

How would you adjust the Mediterranean Chicken recipe for 2 servings and what type of Italian seasoning do to use?

    Hi Sandy,

    The easiest way would to just use 2-3 chicken breasts instead of 4-6. I use a generic Italian seasoning, but you could use any kind you’d like or have around! It won’t change the outcome of the dish.

What do you suggest to serve as a side dish?

    Hi Kristine!

    Any sort of rice or pasta would go great with this dish!

This looks delicious, but the amount of ads on your site makes me never want to come back!

Can you tell me what the calories and fat are per serving?

    Hi Kimberly! I don’t have the nutrition stats on hand, but my favorite way to get those numbers is using – it’s free and you can just copy and paste a recipe URL from the internet into their calculator and it will do the work for you!

      Wow! Thanks for this. I am doing a lot of helping-hand cooking for my eighty-somethings (my beloved elderly folks) these days and this will help me help them.

Would this be suitable for freezing? I do all my meal prep in bulk and freeze my lunches.

    Hi! This dish would freeze well and make a delicious lunch meal prep!

Looks great – do you buy prepared roasted red peppers? Or roast them yourself? If you buy prepared, are they canned, jarred, or what?

This is delicious! I made this today with bone-in chicken thighs. The chicken was falling off the bone, juicy and tender. I sauted the onions and garlic before putting in the crockpot. Will make this again!

    Hi Jennifer – Did you use bone in chicken thighs with or without the skin?

Hi there! This looks yummy! Is it okay to start the cooking process day before and just reheat day of? I want it to taste the same of course but don’t have that much time tomorrow when everyone comes over.


Do you roast the red bell peppers yourself or buy them roasted? Do you think green would work?

    You can purchase the peppers already prepared in a glass jar.

I see what looks like red peppers in the photo but they aren’t listed in the ingredients. Am I missing something?

This looks amazing. Do you think I could throw in some grape tomatoes as well?


I made it today and it was so delicious!! It is super easy to make. I didn’t have a lot of time so I opted to do the two hours on high but used thighs instead of breast, they were very moist.
This will definitely be something I make often.😊

Can I use a whole chicken instead of parts. And not brown it.?

I tried this for my family of four tonight and it was DELICIOUS!!! Even the 3 yr. old & 5 yr. old enjoyed it! I served it over orzo pasta and topped with fresh thyme. Also used red/purple onion instead of yellow. YUM…definitely a ‘keeper’!

    Hi Jill! Thanks for your feedback! I love to hear that your whole family was able to enjoy this meal!

This sounds amazing and will definitely make it as written for my family however I was thinking about making it when my in-laws come to visit and my MIL can’t have the peppers could I substitute sundried tomatoes

Just made this w/ chicken breasts. it was amazing wouldnt change a thing!

I made this tonight and absolutely loved it!! I didn’t brown the chicken ahead of time, but it still turned out fantastic! I added some olive oil to mine and increased the amount of lemon juice and garlic. So good!!

Tried your recipe and it was delicious! Might want to add the tomatoes on the ingredients list and when they should be added. Thanks!

Absolutely delicious! Will be making this over and over again.

I made this on Sunday and it was FANTASTIC!!!!! I also added artichoke hearts. YUMMY!!!

Just finished eating dinner. This was awesome! Used chicken,breasts on low for 4 hours and skipped the browning step as I was running late. Swapped out the red peppers for sundried tomatoes packed in oil since I hate peppers. Was a great hit, very moist, everyone loved it. Dumped the extra juices and bits in our Farro mushroom pilaf to spice it up for tomorrow’s dinner.

Is there enough liquid to make the chicken moist? I feel like there must be some sort of liquid missed? Is the Italian seasoning the spice or the salad dressing?


    The Italian seasoning should be the spice, and this chicken always comes out nice and juicy when I make it!

Very good, i added artich hearts. I did not brown the chicken but i did saute’ the onion and garlic before adding to the pot. Made it with whole wheat orzo.

This was a tasty dish. I was serving with rice so I added 3t of chicken broth to crock pot while cooking. Chicken breast are so lean I thought I would juice them up a little. I would make again.

It looks Delicious but im just wondering how many calories in One serving

    Hi Parmida – My Fitness Pal has a great tool that will tell you the nutritional information for this recipe or any other recipe on my site.

Made this dish tonight. It was delicious!!! I added a little white wine and some artichoke hearts.

Tiffany, your recipes are amazing. I am a beginner, but with your recipes I cook as a profesional…lol. Yesterday we had this chicken for dinner and everybody loved it. today is slow cooker pork carnitas…greetings from costa rica.

Like others, i agree the chicken was more rubbery than tender. The sauce itself was great. I will make the sauce in the future, and use on shrimp. Or, make with cubed chicken and sLiced sausage.

How do you pour the ingredients you described on the chicken. the only flud is 2 tablespoons of lemon jucie. huh

    Give that recipe a try! It works out! 😉

Very goood dish. I’ve tried different mediterranean recipies but this so far is tops. not only is it very tasty but much more healtier than othes. Thank you for sharing.

    Hi Jerry- I am SO happy to hear that this is your favorite Mediterranean recipe! Thank you for the great feedback 🙂
