This Classic and Healthy Wild Rice Casserole is made with mushrooms and onions. A hearty vegetarian or side dish that’s easy to make and guaranteed to please a crowd. Gluten Free + Low Calorie + Vegan
Wild rice, do you love it or do you hate it? Do you even know what it is? Are you eating the boxed version? If so, we really need to talk!
First, let’s get one thing straight. Wild rice is not a grain, it’s a water grass seed that grows in wet fields. It has a chewy, nutty flavor and purplish hue. Nutritionally, wild rice has TWICE the protein and fiber as brown rice and is high in B vitamins (hello energy!).

Wild rice is naturally gluten free and low in calories. This is true only of the non-boxed kind. Boxed versions generally are contaminated with gluten and contain other additives that are disrupting to the balance of the body.
When you buy wild rice, look for bagged versions that only contains the rice on the ingredient lists and the label should have a certified gluten free stamp. Some markets even wild rice available in bins so you could go that route too.
Growing up in Wisconsin, I’ve been spoiled when it comes to wild rice. It grows abundantly in the Great Lake region, primarily near Minnesota where my Dad’s family lives. In fact, my uncle goes out in his canoe and harvests wild rice during the year, has it processed then disperses it to the family.
So we’ve always had fresh wild rice on hand. It’s been a staple in our meals for as long as I can remember. I guess there’s only so much wild rice one person can eat, and I’m not complaining!
Healthy Wild Rice Casserole
The original wild rice casserole recipe, well wasn’t the healthiest. It was handed down to my mother from my grandmother, and called for something crazy like 4 sticks of butter. Yikes! Talk about a grease fest.
I love wild rice so I transformed this traditional family dish into a Healthy Wild Rice Casserole by adding more onions for moisture and swapping the butter for extra virgin olive oil. The recipe turned out moist, nutty and equally flavorful as the original, only better for you!
This Healthy Wild Rice Casserole is simple to make. It does take an hour to bake in the oven, but the oven’s doing the work and frankly the wait is well worth it! This can be served as a side paired with a green vegetable and lean protein like chicken, fish or turkey. It’s warm, comforting and wholesome. Perfect for a winter meal!
For those of you new to baking rice in the oven, it does bake. In fact, I have another casserole recipe that readers comment all the time confused they’re baking uncooked rice in the oven (even though the recipe card already says this).
YES, you bake the rice uncooked! The trick is using a small casserole dish. Anything too big will not allow the liquid to boil which means it could take three hours to cook instead of one.
But what I really want you to know about this recipe is that most of the time you don’t have to do much to “healthify” a dish. Simple swaps can take a dish from a cholesterol fat bomb to a heart and waist friendly dish that tastes amazing.
My challenge to you is to think about traditional family dishes you have and ways you can transform them into healthier versions.

What I Used For The Recipe
My mom always served wild rice when I was growing up and I’ve always loved it. This casserole sounds delicious — love the addition of the mushrooms! Hooray for sides that are also healthy!
I think it’s often forgot about or people don’t know it exists. Glad you do!
this is my favorite combo! Mushroom and wild rice. Ahh that nutty goodness. Make me some, mm k? I”m coming over!
You better! You’re gonna be closer to me now with the move. 🙂
What size casserole dish do you use to bake it in?
The one I used was small, probably 10X7. I got it at Walmart, it has a glass cover which is perfect for making this.
Yum! I love rice but I hate mushrooms! I need to try this baking uncooked rice thing, I do it all the time with Quinoa but never tried it with rice!
I don’t love mushrooms either, but in this recipe I do. And you must learn to bake rice girl!
Wild rice is the only type of rice I actually like! Probably because it isn’t rice, so there you go 😀
Ha! I knew we were friends for a reason. 🙂
This is a great recipe, I love wild rice. It’s the best out there! 🙂
I couldn’t agree more. 😉
Canned mushrooms ?? Nooooooooo
This website is for positive comments and positive people. If you do not have a positive comment, do not leave it. Keep it to yourself. There is nothing wrong with organic mushrooms. They are actually very nutritious.
Could you use fresh mushrooms? Just bought some.
I’ve never tried, but I’m guessing you could!
Can I freeze the leftover? We only have 2 in the household 🙂 Thanks. It looks very yummy and will certainly try to make it. Just got some wild rice today, try to change our eating habit from white rice to wild rice.

I haven’t tried it, but I wouldn’t freeze the leftovers. Any rice doesn’t taste good frozen then thawed. You could just store it in the fridge for a week and eat it throughout the week with others meals.
Hi, can you tell me roughly how much one serving should be? It says 97 calories per serving, but doesn’t say how much the serving should be. (How many oz?)
About 1/2 cup.
The nutrition information says serving size one cup. Is this one cup or half a cup? I want to try this and want to have accurate calorie information. Thanks, looks yummy!
Hi Heather, 1 cup is the serving size. Enjoy!
I added chicken to mine for a little extra protein and flavor and I used chicken broth. It turned out great.
What are your suggestions on cooking it in a slow cooker?
I haven’t tried it, but I would suggest you follow the same ingredients but add them to a slow cooker instead of oven. You’ll need to experiment with the times, but 4-6 hours on low or 6-8 hours on high is where I’d start.
So tasty! I used 16 oz of fresh mushrooms, cuz I dont care for canned mushrooms, and added 3 small zucchini to the mix and it was delicious! I was surprised by the lack of seasonings in the recipe, but the veggies carried themselves and you really dont need any! Would def make again.
So good! I was intrigued by this recipe because I wasn’t aware there was a difference in wild rice. Great recipe!
Glad you liked it!
I made this last week using Lundberg’s wild rice mix/medley with fresh shitake mushrooms and it was OUTstanding!!
I loooove this dish! I recently became vegetarian and am always looking for some really good and savory recipes….this one is IT! Thank you for giving it to us!!
Aww thanks for taking the time to let me know you enjoyed that! My Grandma would be so happy to hear this.
Hi! I’m making this dish tomorrow. I noticed you gave a measurement for water, but then you said to check the package for water measurement. I will be using fresh wild mixed mushrooms. Should I still use the exact amount of water the package says for a cup of rice? Even with the added veggies? I’m AWFUL at cooking wild rice and don’t want to screw this up! I’m tossing it with a vegan homemade cheese and adding carrots and chopped broccoli after it’s cooked to make it a full meal. I’m super excited!
Wow that sounds delicious! Well, I didn’t give a measurement for water rather for broth. You probably could use water, but it’s more flavorful with the broth. As long as you measure the rice to the 1 cup, 3 cups of broth should be fine. Just know all grains (even different brands) can have slightly different results. I honestly think you will be fine. Many of my clients make this and love it.
If I want to add more veggies so it’s more of a full meal rather than a side dish, what do you recommend? Carrots? Celery? Broccoli? Zucchini? Other? And if any of these would work, when should I add them? And no spices at all? Thank you.
You could add celery probably without affecting the taste or having to add spices. I’d just cook it with the onions. Nothing else would really go with the casserole. If you wanted more vegetables, then add a side of roasted broccoli or carrots with the meal.
Can you freeze this casserole?
I haven’t tried it, but I’m guessing it wouldn’t taste great if you did it. Wild rice is very watery so it would be even more watery if you froze it then reheated.
