Looking for a healthy flavorful comfort-food casserole?
This Creamy Mustard Tomato Chicken Casserole is my go-to on nights where I want a warm yummy easy-to-make casserole. ( Especially one with a really satisfying creamy sauce! )
This casserole is made of bite sized chicken, sweet potatoes, and carrots that are topped in a rich savory tomato, mustard, and coconut cream sauce. It’s ridiculously good.
It’s also really easy to assemble! AND it just so happens to be Paleo, Whole30, Gluten-free, Dairy-free, and Grain-free.
I made a similar recipe on my blog several years ago, but over time I started to tweak it.I added more chicken. I also added sweet potatoes.
I changed the proportions of the sauce so that the sauce was creamier (thanks coconut cream! 🙂 ), and so that there was more of it.
Because…you are going to want more of this sauce!
Ingredients needed to make this Creamy Mustard Tomato Chicken Casserole:
- olive oil
- garlic
- onion
- carrots
- sweet potatoes
- chicken
- tomato paste
- dijon mustard
- coconut cream
- thyme
- bay leaf
The sauce here is sweet from the tomato paste, and a bit spicy from the mustard. The tomato mustard flavors are then balanced out by the coconut cream, which adds a creamy richness to the whole dish.
Creamy rich sauce is what makes casseroles great, am I right?
Then the creamy mustard tomato sauce soaks into the carrots, sweet potatoes, and chicken as it bakes.
It is just wonderful.
There is no wonder why this Creamy Mustard Tomato Chicken Casserole is such a crowd pleaser in my house.
Every single time that I make it my husband comments that he loves the sauce.
Who knew a yummy sauce could be made of only 3 ingredients?!
Speaking of sauce… you need something to pour it on top of.
I love eating this Creamy Mustard Tomato Chicken Casserole on top of mashed potatoes or steamed broccoli.
If I’m feeling extra cozy, I make white rice and let the rice absorb the creamy mustard tomato goodness. Drool.
This casserole is on my regular meal rotation, and I’m hoping it becomes part of yours.
Tip: make sure the potatoes are thinly sliced so they cook all the way through!
Enjoy!

Loved it! Made as directed but didn’t have the bay leaf and still tasted wonderful. My oven cooks hot so I shortened the oven time to 20 mins not to overcook chicken. Perfect!
Happy to hear it! 🙂
This recipe is soooooo good!!! I never take time to comment on anything online, but I had to make an exception for this, it’s that good! I’m on day 16 of Whole 30 and this recipe is going to be a lifesaver!
Ps. I put it on top of butternut squash “noodles” and it was perfect!
Yessss! So happy to hear it! I love the idea of eating it with butternut squash noodles. 🙂
That sauce does sounds amazing!! Question though – I’m allergic to coconut milk..any recommendations for substitutes? Can’t wait to make this!
Heavy cream would work great instead of coconut cream. I’m not sure if you are trying to keep it Paleo and Dairy-free, but if you aren’t heavy cream tastes great here!
I love that this recipe only takes 45 minutes to prep and cook. I’m always looking for my quick chicken dinner recipes.
What a great main dish. I really like your flavor combination and I bet the sauce is amazing. The chicken in the creamy sauce would flavor the rice. This would be such a fantastic weeknight dish. Will be trying it soon because I’m always looking for ways to make chicken.
That’s a perfect dinner. Love the flavor profiles here. The sauce indeed looks creamy and delicious!
I can’t believe you made this sauce with only 3 ingredients! That’s so impressive. It looks super delicious and healthy.
I love how simple and easy this is and that color – so pretty. I love creamy and mustard so this is definitely something I will enjoy. Saving this for later. Sounds yum.
You had me a coconut-cream sauce! 🙂 My husband and I are trying to go back to being paleo, and I think that this recipe is the first one I’ll try. It just look so good!
Wow, sauce, indeed looks creamy and this dinner looks easy to make. I will make a lot for next day’s lunch.
This sounds so good! I’m always on the hunt for creamy chicken casseroles to serve up throughout comfort food season!
Yum! this looks so good. It’s soon going to be casserole season again! Pinning on my recipes to try board.
What a perfect dinner for our family! Loving the combination of sweet and spicy in this sauce! So flavorful!
