How to make vegan stuffed Portobello mushrooms
The recipe card at the bottom of the page has the full list of ingredients with measurements and instructions.
STEP #1: Making the cheese sauce is as simple as boiling a pot of potatoes, onions, and carrots, adding them to a blender with spices, and blending until smooth.
This recipe makes approximately 1 quart and can be stored in the refrigerator for up to 2 weeks to be used on baked potatoes, vegan tacos, homemade veggie pizza, and so much more.
STEP #2: Prep the portobellos by washing them and removing the stems, but don’t toss those stems out because we’re going to use them in the stuffing because there are so many health benefits in them.
I also like to remove the gills using a spoon to scrape them out. Though this is optional, I really think it’s worth the few minutes it takes to clean them out to keep this dish from being dark are murky.
STEP #3: Chop up the stems from the mushrooms, shallot, garlic, and red bell pepper and set them to the side.
Add 3 tablespoons of veggie broth, sliced shallots, garlic, and chopped mushroom stems to a non-stick skillet. Sautee until caramelized, about 5 minutes. Add additional veggie broth to keep from sticking if necessary.
Add another 3-4 tablespoons of veggie broth and red bell peppers and cook another 4 minutes.
STEP #4: Toss in the beans, fire-roasted tomatoes, Italian seasoning, smoked paprika, garlic powder, and salt & pepper, and cook for approximately 5 minutes on medium heat.
Toss in spinach and cook until wilted, approximately 3 minutes.
STEP #5: Remove the mixture from the skillet, pour it into a bowl, and set it to the side while you cook the mushroom caps.
Add 1/4 cup veggie broth and 3 tablespoons balsamic vinegar to the skillet. Then place mushrooms in the pan, stem side down. Cook for about 5 minutes. Flip and cook another 5 minutes.
STEP #6: Fill each mushroom cap with an equal amount of spinach mixture and drizzle the balsamic pan drippings. Drizzle with a few tablespoons of cheese sauce.
Transfer mushrooms to a baking dish and place in the oven at 400°F for approximately 5-8 minutes until the cheese sauce gets bubbly. Serve immediately.

Frequently Asked Questions
Yes, you can prepare the stuffed mushrooms in advance. Assemble the mushrooms with the filling, store them in the refrigerator, and bake them when you’re ready. They can be made up to 24 hours ahead.
To avoid watery mushrooms, bake them for a few minutes before adding the stuffing to release excess moisture. Alternatively, remove the gills from the mushrooms, which can help reduce water content.
You can customize the filling by adding ingredients like quinoa, lentils, roasted vegetables, or plant-based proteins like tofu or tempeh. Different herbs and spices can also add variety to the flavor.

Instructions
- The first thing you'll need to do is make the cheese sauce. Normally, I have some of this vegan cheese already on hand because we use it with so many other dishes. If I don’t happen to have some in the refrigerator, there’s likely some in my freezer. Making the cheese sauce is as simple as boiling a pot of potatoes, onions, and carrots, adding them to a blender with spices, and blending until smooth. See instructions below.
- The mushrooms need to be the large dinner size and not the smaller ones like my stuffed appetizer mushrooms. Prep the portobellos by washing them and removing the stems, but don't toss those stems out because we're going to use them in the stuffing.
- I also like to remove the gills using a spoon to scrape them out. Though this is optional, I really think it's worth the few minutes it takes to clean them out to keep this dish from being dark are murky.
- Chop up the stems from the mushrooms, shallot, garlic, and red bell pepper and set them to the side.
- Add 3 tablespoons of veggie broth, sliced shallots, garlic, and chopped mushroom stems to a non-stick skillet. Sautee until caramelized, about 5 minutes. Add additional veggie broth to keep from sticking if necessary.
- Add another 3-4 tablespoons veggie broth and red bell peppers and cook another 4 minutes.
- Toss in the beans, fire-roasted tomatoes, Italian seasoning, smoked paprika, garlic powder, and salt & pepper, and cook for approximately 5 minutes on medium heat. Toss in spinach and cook until wilted, approximately 3 minutes.
- Remove the mixture from the skillet, pour it into a bowl, and set it to the side while you cook the mushroom caps.
- Add 1/4 cup veggie broth and 3 tablespoons balsamic vinegar to skillet. Then place mushrooms in the pan, stem side down. Cook for about 5 minutes. Flip and cook another 5 minutes.
- Fill each mushroom cap with an equal amount of spinach mixture and drizzle the balsamic pan drippings. Drizzle with a few tablespoons of the cheese sauce.
- Transfer mushrooms to a baking dish and place in the oven at 400°F for approximately 5-8 minutes until cheese sauce gets bubbly. Serve immediately.
Creamy Vegan Cheese Sauce
- In a medium pot, bring about 3 cups of water to a boil. Place potatoes, carrots, and onion in the pot and allow to cook until veggies are tender approximately 15 minutes. Cooking time will vary based on how small the veggies are diced.
- When veggies are tender, drain and place them in a blender. NOTE: reserve 1 cup of the broth, and add to blender. Add all the remaining ingredients, and blend until smooth.

Hi…new to this, so can you please tell me whether the potatoes are to be peeled before cooking for the cheese sauce? Thanks!
Renee- Yes, I would peel the potatoes before cooking to give the cheese sauce a nice creamy texture. Hope you enjoy this recipe!
That is absolutely brilliant!! We loved it! We will be adding it to the “favorites” rotation! Thank you
Your family must be mushroom lovers too. Glad that it is now a ‘favorite’ at your house too!
Thank you so much for this delicious recipe Terri. I find all your recipes amazing and easy to prepare. Thanks again for sharing them. The cheese sauce Yum!!
You’re welcome, Suzanne! 🙂
I love all your recipes, and I make this cheese sauce at least once a week. thanks
Thanks so much, Gloria! I may or may not have an addiction to the cheese sauce as well. 😉
The recipes look wonderful and I look forward to trying them. I was a bit surprised when I hit print on the lasagna recipe and it printed out 10 pages. In future I will do a cut/paste of the directions and transfer to a Word sheet, but might there be a way for your printed copy to perhaps be directions only and one page in length. Just a thought and thank you for the great recipes which I look forward to trying.
Hi Janice! I know exactly what you mean about printing so many pages. Unfortunately, since I use a free recipe plug-in with the blog,I haven’t found a way to make changes to the printing options. However, once you click ‘Print,’ your computer should give you a preview and the option as to which pages to print. You can then designate which pages you want. I hope this helps a little, and I really hope you enjoy the lasagna! 🙂
Thanks so much for this delicious sounding recipe. I will certainty make it.
I am a newbie to the site and find it very interesting
Thank you
