This week for Sunday Supper we are making Easy Supper Recipes so I thought this slow cooker chicken ratatouille stew would be a good one to make. Everyone likes slow cooker meals for busy days and this chicken vegetable stew is easy, hearty and even low calorie!
I love ratatouille because of it’s tasty combination of tomatoes, eggplant, peppers and zucchini. However I normally consider it a side dish. Today I wanted to make it a bit more substantial for a main dish instead, so I added some chicken thighs and cooked the whole dish in a slow cooker. It was so easy and tasty that I’m sure we will be eating this again and again.
What is ratatouille?
Most people know about the movie Ratatouille involving a rat that is a culinary genius but not everyone has had this delicous dish. Ratatouille is a French stewed vegetable dish. It has been made many different ways but it usually includes tomato, onions, zucchini, peppers and eggplant.
I used those same basic ingredients but added some chicken thighs to make this slow cooker recipe more of a dinner than a side dish. It came out perfect and was really easy to make.
Making slow cooker chicken ratatouille
If you want you can just put everything in the slow cooker and be done but try it this way. Pour a little olive oil on the bottom, then onions and half of the tomatoes. Next put in the vegetables and top them with the chicken thighs.
Now take the remaining tomatoes and mixed in the tomato paste, Better than Bouillon base, garlic and spices. Spoon this over top and cook on low for 8 hours. Times may vary depending on your slow cooker.
Slow Cooker Ratatouille Recipe Notes
- I used chicken thighs but you could also use breasts if you wish.
- I also used boneless, skinless chicken so I could shred it at the end. If you want you can keep the chicken as is and serve it separately from the ratatouille.
- Better than Bouillon gives this an added flavor boost. You can substitute chicken bouillon if you don’t have BTB.
- At the end I shred the chicken a little bit and mix well. If it’s still too watery for your liking, you can take the lid off the slow cooker and turn up the heat for 10 minutes.
- You can eat this dish as is or serve it over rice or pasta. I like to grate Parmesan cheese over top sometimes.

PLEASE NOTE: I have updated this recipe to make it a bit lower in carbs and it ended up a bit more tasty! The video is older and you might notice a few differences. The changes I made were to use less onions and tomatoes and add tomato paste, bouillon and a little more spice.

Heather
Is the diced tomatoes canned or do you dice fresh tomatoes?
Denise
Hi Heather, I used a canned tomatoes but fresh would work as well. Hope you like it!
Heather
I loved it! I used fire roasted canned tomatoes and it was absolutely delicious!! I was thinking next time adding mushrooms in the last few minutes of cooking.
Denise
Hi Heather, so glad you liked it. I need to make this again and I’ll try the mushrooms too!
Alba
Is it possible to cool it at high or it has to be at low? I wany to make it for tonight but I don’t think I’ll have time!
Denise
Hi Alba, I think you could cook it at high. Good luck!
Macey
Would you recommend doing this in a pressure cooker? And if so for how long? Thanks!
Denise
Hi Macey I guess you could be I would be afraid it would turn to mush. If you want to try it, I’m guess about 8 minutes. That’s what I did for these Instant Pot chicken cubes. https://mylifecookbook.com/instant-pot-chicken-cubes-low-carb-meal-prep/
Good luck … sorry I’m not much help.
Jill
How much is a serving? I cup?
Denise
Hi Jill, I am not sure but I would say a cup is a good estimate. I usually take the recipe as a whole and estimate how many it could feed rather than measure by volume or weight. Hope that helps and that you like it.
Karly
Perfection. Especially during the cold Midwest winter, this is exactly what I want to warm me up. I can’t wait to make a big batch of this stuff and eat on it for days!
Denise
It does make a lot! Enjoy!
Caroline
I love ratatouille and this sounds a great variation. Your video shows how easy it is too!
Denise
Thanks Caroline, it was really easy.
Monica
Like you I adore the flavors of ratatouille and adding chicken to it is genius! I’ve tried adding white beans to make it more substantial but I’ve never thought to add chicken. Brava Bella!!!!!
Denise
Hi Monica, I love the idea of white beans! I’m going to try that next time.
Liz
What a marvelous recipe! I’m a huge ratatouille fan, too—and I just won’t mention there’s eggplant in the recipe when I feed it to Bill. Maybe he won’t notice???
Denise
My husband doesn’t like eggplant either! What is wrong with these guys! 😉
The Ninja Baker
Absolutely gorgeous Denise! Definitely a keeper recipe for my slow cooker =) P.s. Did you ever see the Disney movie?
Denise
Yes I have and my son asked me if I was making rats. 😉
Christie
That looks amazing! I love all those colors and flavors.
Denise
Thank Christie! It’s very simple (like most of my recipes) but I really liked it!
Cindy @CindysRecipesAndWritings
I can always use more slow cooker recipes! I bet this chicken gets so tender!
Denise
Yes it’s more like shredded chicken.
