There’s nothing better than a comforting casserole and this simple and easy recipe combines a French classic dish with succulent chicken and creates a brand new easy one pot dinner experience. 

Traditional Ratatouille is a vegetable stew that’s not only colorful, but extremely comforting – not to mention healthy!

By adding seared chicken pieces, you turn this wonder dish into a full baked dinner the whole family will love. This is what makes it the best Ratatouille recipe around.

Classic ratatouille combines aubergine (eggplant), zucchini, bell peppers and tomato. With this recipe we decided to stray from the classic and switch aubergine (eggplant) with butternut squash – just because my family is not the biggest fans of it. It still tastes wonderful without it.

We also use canned tomato, which helps make everything saucier and even more delicious.


How To Make A Ratatouille Chicken Casserole One Pot Dinner:

The rest is incredibly simple:

  1. Season and sear the chicken.
  2. Chop the vegetables and add to a large casserole dish.
  3. Add all the rest of the ingredients and pop in the oven.
  4. One hour later – Voilà!
  5. Dinner Is Served.

Another thing we do a little different is adding a touch of curry powder. Even though curry is a very strong flavor – it doesn’t overpower the dish, it only adds a subtle new depth of flavor.

The only thing better than a one pot meal to make your busy weekdays just a little easier, is a healthy one pot meal. This one ticks all the boxes and will definitely make it into your menu rotation.

  1. 4 stars
    I doubled all the seasonings and herbs while searing cubed up chicken breasts. Added whatever vegetables were in the fridge and baked. Wonderful, aromatic and looks like hours have been spent prepping it.

  2. Sounds like a great recipe but not clear about the seasoning. Is the celery seed, curry, thyme, oregano added to rest of ingredients after chicken is seared? Squash is a great idea but I would also add eggplant, which I love. Maybe 1and 1/2 cups each of squash and eggplant. What do you think? Thank you for your reply.

    1. Hi Catherine, sorry for not getting back to you sooner. Before searing the chicken I just added a good amount of salt, pepper, coriander and paprika to give the chicken good flavor – this is extra from the measured seasonings which gets mixed in with everything else before baking to flavor the whole dish. I will adjust my recipe card to make that step clearer. Also, eggplant is a great addition, we just decided to forego it for personal taste, but I would recommend adding it if you love it 🙂
