Ingredient Rundown
This is just an overview – jump to the recipe card for exact measurements and instructions!
- Portobellos: These fungi make the perfect vegan gyro meat, especially once cooked down. Look for firm, plump caps at the store.
- Olive Oil: We’ll use this Mediterranean staple to help our spices cling to the mushrooms (and to sneak in some healthy fats). Opt for extra-virgin olive oil for the best flavor.
- Lemon Juice: Freshly squeezed lemon juice brightens the dish. If you have a lemon on hand, use it! If not, bottled lemon juice works in a pinch.
- Soy Sauce: This salty, umami-packed sauce adds savory depth to the portobellos. If you want a gluten-free alternative, swap it out with tamari.
- Extra Seasonings: Oregano, smoked paprika, salt, and pepper give the mushrooms an earthy flavor with slightly spicy, smoky undertones. And garlic? Well, you can never go wrong with garlic.
- To Serve: Round out your gyros with feta, store-bought or homemade tzatziki sauce, fresh veggies (like tomato, red onion, radishes, and lettuce), and pillowy pitas (found in the bread aisle). You can also use whole wheat or gluten-free pita if that’s your jam!
Making Vegetarian Gyros Is A Breeze
- Clean the mushrooms with a damp paper towel.
- Coat in a flavorful marinade.
- Cook on the stove for just a few minutes.
- Assemble your vegetarian gyros, then dig in!

These are so incredibly delicious! We’ve made them at least twenty times now, including for guests. Always a delight! We serve them with the feta tzatziki, which is truly scrumptious. Together with a nice pita and some veggies, it’s a combo that can’t be beat!
So happy to hear it, Fern! Thanks for dropping in to let us know how it went!
Excited to try these probably this weekend. Do you think they could be grilled?
Yes they can! Just be sure to use a well greased area of the grill.
This was delicious! My picky eater loved it. I did not add the salt but added feta dip instead. I also sautéd red peppers and onions added tomatoes and lettuce. Tzazkizi sauce is a must!! Great recipe, glad I found. It’s a keeper!!
YAY! So happy to hear you all loved it, Lisa! 😀
These came out so tasty!😋 Loved the dressing the mushrooms were tossed in. Even my husband, who loves traditional meat gyros, enjoyed them.
So delicious! Substituted Asian mushrooms like oyster and shitake and they worked great.
Made these multiple times and is now a staple recipe at our house! Devine flavor. The feta tzatziki is also a must if making these.
I just made these for dinner with the exception of substituting the portobello mushrooms with king oyster mushrooms and they are 10/10! I feel like using portobello mushrooms would be a bit meh, I’m not a huge fan of the consistency so I’m glad I used the king oyster mushrooms. Using the tzatziki sauce is a must!! I also added some fresh chopped mint. Definitely making these again soon!
Any recommendations for what kind of herb’s and spices work well?
Oregano, dill, garlic, and onion would all be delicious!
I Love this recipe. It is my regular meal rotation! Even my in-laws (who don’t like food) raved about this meal! Thanks for sharing!
Just want to say I’ve had this recipe bookmarked for quite awhile. Made the recipes dozens of time. Realized today I never rated it.
Soooo good I make these instead of buying real gyros. Just top notch tasty.
YAY! So happy to hear it! 😀
