If you are looking for rustic hearty meal with creamy and rich flavors – you came to the right place! The combination of mushrooms, wild rice and a cream sauce pair so beautifully in this chicken casserole. Mushroom Chicken & Wild Rice Casserole is a wonderful weeknight meal that will be sure to make everyone happy. A cold wintery evening is perfect for this belly warming meal.

I have included a homemade onion soup seasoning mix that you can use for this recipe as well as other recipes what call for an onion soup mix. If you prefer to use a premade onion soup mix, it will work just great for this recipe as well, just be sure to look at the measurements. The only reason I make my own is because I try to limit the amount of salt and preservatives that I feed my family.
If you do not care for wild rice, you could certainly use all long grain rice for this recipe. I like to use a little bit of long grain mixed in with the wild rice just give it some balance. Since wild rice tends to maintain a bit of bite even when fully cooked, I like the soft long grain rice in there to vary the textures.
Now Let’s Get Cookin’!
