Recently I remade this very old recipe and decided to completely update it today (4/21). Originally I made these keto vegetable stuffed mushrooms and also used the stuffing and put them on mini cauliflower rounds.

I decided to take out the cauliflower rounds recipe but I will make that a separate post in the future. If you came back looking for it, please just comment below and I’ll hook you right up with that recipe in the meantime.

So these stuffed portobello mushrooms have a tasty Mediterranean flavor from sun dried tomatoes, garlic, feta cheese, spinach, herbs and spices etc. And I didn’t use any breadcrumbs!

I could eat the stuffing alone with spoon! But it makes a wonderful gluten free and low carb stuffing and it’s super easy.

Ingredients I used for the stuffing.

First let me say that I used baby portobello mushrooms for stuffing. I like these better than white button mushrooms because they are meatier and have a firm texture.

The delicious stuffing ingredients were mushroom stems, spinach, cauliflower rice, sun dried tomatoes, garlic, feta cheese, oregano, basil, salt and black pepper.

Note there is no bread or breadcrumbs and you won’t miss it.

Let’s make our vegetable stuffed mushrooms!

1. First you want to clean the mushrooms and take out out the stems. Save them because they will go in the stuffing.
2. Spray a baking sheet with cooking spray and place the cleaned mushroom caps on it. Spray the underside first, then flip them over and spray them again. Bake them in a preheated oven of 400°F for 10 minutes.
3. While they are cooking, add the olive oil to a skillet and heat to medium high heat. Finely chop up the stems and add them to the pan. Let them saute for a few minutes.
4. Next add in the cauliflower rice, chopped sun dried tomatoes, garlic, oregano, basil, salt and black pepper. Saute for a few more minutes.
5. Lastly add in the chopped spinach and mix until it wilts completely. Take the mixture off the stove and fold in the feta cheese.
6. When you take out the mushrooms let them cool a bit so you can handle them. Then take the vegetable mixture and stuff all of the cooled mushroom caps and place onto a baking dish
7. Place back into the oven and cook for 15 minutes more until they are golden brown. There is a printable recipe card below for your convenience.
8. Note you can sprinkle fresh minced parsley on top if you are taking these to a party though it’s not necessary.

How to clean mushrooms.

You don’t want to rinse mushrooms as they will absorb the water due to their spongy texture and get slimy. So all you need is a damp paper towel to gently wipe them one at a time to get off the loose dirt. You can also get mushroom brush though I don’t have one.

If you don’t have time you can lightly rinse them but hurry and dry them off with a clean kitchen towel so they don’t absorb the water. (learn more)

Is this a vegetarian recipe?

Technically it is not because feta cheese uses animal rennet. However it adds lots of flavor. Luckily there are many brands of feta cheese that are vegetarian and I found a great list of these vegetarian cheeses here.

Two brands to try are Aldi’s Specialty Selects feta or Whole Foods 365. Check the link above for more brands of vegan cheese. You could also try nutritional yeast though it won’t be the same.

This recipe IS gluten free though as I’m not using any breadcrumbs like traditional bread stuffing.
