When fall rolls around I begin to crave things like chili, potatoes, creamy soups, and pork roast. My body knows exactly when it is time to nest for the winter and immediately wants to make sure my body is nourished.
I do in fact love a good chili and we always have potatoes in our pantry, but I try to incorporate healthy green vegetables and whole ingredients like quinoa into my diet throughout the fall and winter months!
This Apple Chicken Sausage Quinoa Casserole is a great meal to add to your list for the week. It has delicious seasonal vegetables like sweet potatoes and brussel sprouts. All you have to do is throw everything into the casserole dish, brown your chicken sausage, and mix up your dressing. That’s right, THE DRESSING. The dressing for this quinoa casserole takes this dish to the next level.
One other thing I really love about this quinoa bake is that I usually have everything I need for this dish in my pantry or the refrigerator. Stock your pantry so that you are ready to make this quinoa casserole whenever you crave it!

Q’s About Quinoa
What is quinoa good for?
Quinoa is packed with protein and fiber. In fact, quinoa makes up a complete protein on its own! Adding quinoa into vegetarian and vegan dishes is a great way to add protein to any meal. You can also incorporate quinoa flour and quinoa flakes into baked goods and oatmeal. There are so many options!Is Quinoa better for you than rice?
It all depends on what your personal nutrition goals are! Quinoa is higher in protein, but rice is packed with fiber. Please talk to an RD for your specific nutritional needs.Is quinoa a superfood?
Quinoa is a superfood. In fact, did you know that quinoa is not even a grain? Bobs Red Mill talks about how quinoa is a part of the quinoa, spinach, and beet family (crazy, right?!)Is quinoa gluten free?
Yes, quinoa is naturally gluten free! However, if you are celiac please make sure you do research on where your quinoa is processed. Sometimes there is cross contamination in factories (yikes).Is quinoa paleo?

This was so great! I made this for meal prep and it turned out awesome! I love that it all cooks in the one pan. I hate doing dishes and honestly I hate cooking and this was so simple. I’d love to make a spicy version of this with jalapeno chicken sausage and regular potatoes. Do you have any recs for what to do with the dressing?
Any suggestions to replace sausage so it’s strictly vegetarian?
Hi Lee,
How much olive oil to you suggest when mixing the vegetables after slicing? It isn’t listed in the recipe.
Thank you!

I made this for dinner tonight and it was delicious. I followed the recipe exactly and it was perfect. The only issue I had was that in step 2 of the recipe it says to add in the olive oil, but the ingredients list doesn’t list olive oil (except of for the dressing). I drizzled a fair amount on it (maybe 2 or 3 tablespoons) that seemed to work. My husband doesn’t really care for brussel sprouts or sweet potatoes, and he had 2 helpings!
In the picture it looks like there is some kind of cheese on top, am I missing that the directions/ingredients?
The cheese is optional, but we used parmesan!
I didn’t have tin foil but I substituted for aluminum foil, still came out great!
Can you replace the sweet potatoes with butternut squash?
Can you use cooked quinoa?
We recommend not using cooked quinoa or you will likely over cook it!
I made this tonight and followed the recipe exactly but I had some issues with it. First, a cup of uncooked quinoa yields a TON of quinoa when cooked. I felt like I should have only used half a cup because there was way too much compared to the amount of veggies. Also, the sweet potatoes were not soft enough after 60 minutes in a 350 degree oven. I love sweet potatoes but would have preferred them to be much more tender. Maybe I did something wrong. I wanted to love this dish – the flavors are great – I just had some frustration because I thought I had followed the recipe correctly!
Hi Lee! featured this recipe in my fall recipe round up post today at http://physicalkitchness.com/healthy-paleo-fall-recipes/

I made this last week and finally took some to work with me for lunch. the rest I put in the freezer. OMG! it’s really delicious I followed the directions exactly and it’s perfect the potatoes are not hard, like I thought they would be with only 40 minutes, but it’s super good.
