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!

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!
