This best Vegan Stuffing with Mushrooms features baby portobellos and it’s all wrapped up in an easy casserole recipe. Rich flavors makes this a perennial favorite and it shines as a side dish over the holidays especially on Thanksgiving.
Mushroom stuffing is one of my favorite side dishes. I was hoping to make a new dressing that had rich moist flavors that everyone would love. Well, this is it.
Eight ingredients, including the salt and pepper, and they are all very important to include to keep this side perfectly moist with great taste.
This vegan stuffing recipe is loaded with baby portobellos and the main spice is sage. The sage really puts it over the top.
This is a super simple casserole and since mushroom dressing freezes so perfectly it is a great dish to make in large quantities.
You don’t need any gravy to go with it but if you have a favorite vegan gravy, then please, serve it on the side. I am an addict for dressing and gravy.
Speaking of gravy just look at this recipe for Vegan Gravy. It is classic with no funny seasoning additions. This one may just be your new favorite.
I also put it on my Best Vegan Meatloaf too. And, of course, don’t forget the mashed potatoes.

Can Fresh Bread Cubes Be Used for Vegan Mushroom Stuffing?
I tried it with this recipe and it needs the packaged stuffing mix. You need the crusty cubes (seasoned or not) to work with all of the flavorful liquid.
Some years I make a fresh cube bread dressing but to tell you the truth my favorites are this one and my Vegan Sausage Stuffing Casserole. That one has seasoned cornbread mix.
This year I bought extra boxes of Herbed Stuffing Mix so that I can make it throughout the year. True, I freeze it in small batches for lunch but it still goes too fast.
I’m determined to be able to make it after Thanksgiving too. This stuff is that good.
Helpful Tools for Making Cremini Mushroom Dressing
- A casserole dish is a must. You can go with the fancy to the everyday style. The truth is the stuffing makes every casserole shine.
- For almost every recipe you need good measuring cups and measuring spoons. This is a great stainless steel set.
- Good sturdy glass mixing bowls are the best to me. This set is even from Anchor Hocking.
So I hope we are all having Vegan Mushroom Stuffing in our homes this year. I think it will become one of your perennial favorites too.
I want to show you a picture of this vegan vegetable stuffing covered with vegan gravy. It sure was a pleasure enjoying this after I updated the photos.

Below this recipe I have a bunch of photos that I took from the last time I made this recipe for the blog. I mean like about 6 years ago.
We really do love this recipe and have been having it for years. Sometimes even two different stuffings on the Thanksgiving table.
I like to do that when my family comes over. The Vegan Sausage Stuffing Casserole and this delicious mushroom dressing.
BY THE WAY! DO YOU SAY DRESSING OR STUFFING?
I guess it doesn’t matter. It dresses the table and stuffs me. 🙂
Leftovers freeze beautifully. I will make this recipe just to freeze in single-sized servings. It heats so quickly in the microwave and is a really tasty snack or lunch.
- IF FREEZING:
- Let cool to room temperature.
Cover with plastic wrap and then slide into a freezer bag. If you want to put the stuffing into small containers then follow one of the directions as defined in my article Preparing Food for the Freezer - THE NIGHT OF SERVING:
- Remove from the freezer and put in the refrigerator to defrost from 4 to 6 hours.
- TO PREPARE AFTER FREEZING:
- Place the dressing in a microwavable safe bowl and heat on high for about 2 to 3 minutes stirring every minute. Ready to serve.

Absolutely Joshua! I have done that too and it will be delicious!
Hi! Thank you for this post! I gave a question. Can it be made with white mushrooms?
I am so glad you got creative and turned this stuffing into the main meal. It sounds like you did a great job Michele!
This is too good to be just a side dish. Added sliced white button mushrooms to more cremimi, along with Fiji and Grammy Smith apple, plus shallot, scallion and a very small pinch of cayenne. The salt was not used. The sodium in the bag of stuffing was ok. Also added a little thyme and lemon zest. Sauteed your components and mine on high heat,, adding veg stock a bit at a time. Then the seasoned bread stuffing and more stock.
Then grilled Portobello mushrooms were used hold the stuffing. Made 12. This was our main dish.
The first idea was stuffed Portobelli, but the oven was being used for the roasted fillet of beef and lamb. We are an eclectic family group.
So thank you very much for the inspiration. Michele
Hahaha! I was wondering about that ‘word’ Sue. So glad you found this. I actually just switched the title because of that problem. So now it’s stuffing and I still say dressing half the time. 😀
When I saw dressing in the title I thought it was mushroom salad dressing, and that really got my attention. I LOVE stuffing myself with stuffing!
Gorgeous photos! This stuffing looks delicious!
Crimini mushrooms are so amazingly flavorful. This stuffing sounds amazing!
This recipe and you talking about mushrooms inspiring me to make a mushroom lunch! This looks like a tasty recipe.
Yum, yum, yum! I love mushrooms in my dressing! I can eat it all year round and not just for Thanksgiving!! I look forward to trying your dish!! Awesome recipe!
This looks like a great alternative to traditional dressing, or stuffing as we call it in our house! I love mushrooms, I only wish my fella loved them as much as me. I might have to sneak them in more often though.
I for one loooove mushrooms. I would eat this year round, even when stuffing isn’t socially acceptable, like in July. Mmm…
Mushroom dressings are my favorite, I love the meaty texture without actually having meat in them. Great recipe!
This is fantastic. I love dressing/stuffing. Can never get enough of it. This one looks super amazing.

Until last year, I hated stuffing. I’m not really sure why but now, it is my absolute favorite! I cannot wait for it! I’m definitely giving this one a try!
I love trying new stuffing recipes and have never added mushrooms. Can’t wait to try!
Mmmm…mushrooms and sage are such a perfect savory cold-weather combo. This dressing (and I prefer dressing because I like crusty bits) sounds fantastic!
I love cremini mushrooms, and this stuffing looks just perfect! I’ve never tried freezing stuffing, but I’m glad to learn that’s an option for saving time later!
I love stuffing with mushrooms and sage, this sounds absolutely perfect for Thanksgiving! Great recipe!
So.. I am like a 6 year old kid when it comes to mushrooms, I usually try and avoid them, but everything else in this recipe looks delicious so in the wise words of my mother “If you try it, you might like it!”
Oh.My.Goodness! Stuffing and dressing is my FAVORITE part of Thanksgiving. Yours looks amazing!
I love mushrooms, this looks great!
