Vegan Seitan Gyro with Tzatziki Sauce

This Vegan Seitan Gyro with Tzatziki Sauce is SO GOOD. Seitan is one of my favorite vegan proteins. It’s made with vital wheat gluten and you’ve probably seen it if you’ve visited my blog before. I have a seitan steak, a quick and easy ginger beef, and a quick beef stroganoff recipe for all your seitan needs! All delicious and all different. This one here is specifically designed for slicing thinly and putting it on a sandwich like this gyro or a reuben perhaps? Yum! So what is a gyro? A gyro is a Greek dish that is usually made with lamb or pork and served in a pita or flatbread with a yogurt sauce. It’s easily veganized. Make the seitan the night before and then you’ll have your Vegan Seitan Gyro with Tzatziki Sauce within 15 minutes and plenty of leftovers! Let’s get to it!

NOTE: This seitan recipe needs to be made the night before for best results.



This seitan recipe makes a whole loaf and can be wrapped tightly in the fridge for 1 week!

  • 3 cups Vital Wheat Gluten
  • 1/4 cups Nutritional Yeast
  • 2 tsp Onion Powder
  • 2 tsp Garlic Powder
  • 1 tsp Paprika
  • 2 tsp Thyme
  • 1 tsp Black Pepper
  • 2 1/2 cups Vegetable Broth
  • 3 tbsps Olive Oil
  • 1/4 cup Soy Sauce
  • 2 tbsps Apple Cider Vinegar
  • 1 tbsp Tomato Paste

Tzatziki Sauce:

Makes enough for 4 Gyros

  • 1/2 cup Plain Unsweetened Greek Style Vegan Yogurt, or plain vegan yogurt
  • 3/4 cup Cucumber, shredded
  • 1 tsp Olive Oil
  • 1 tbsp Lemon Juice
  • 2 Cloves of Garlic
  • 1 tbsp Fresh Dill
  • Salt, to preference


  • Cucumber Slices
  • Tomato Slices
  • Romaine Lettuce
  • Red Onion
  • Flatbread or Pita, be sure to check ingredients to make sure it’s vegan


Make the Seitan:

  • Preheat oven to 350F
  • In a large bowl, stir together the vital wheat gluten, nutritional yeast, onion powder, garlic powder, paprika, thyme, and black pepper.
  • In another bowl, whisk together the vegetable broth, olive oil, soy sauce, apple cider vinegar, and tomato paste.
  • Pour the wet ingredients in to the dry and knead the dough for a few minutes. It should be slippery, not dry.
  • Roll the seitan dough into a long log. Roughly 5 by 10. Wrap tightly in parchment paper and twist the sides and tuck them under the bottom of the loaf. Think about the wrapping on a piece of candy.
  • Place the wrapped loaf on a baking tray and bake for 90 minutes.
  • The loaf should fill firm.
  • Let completely cool before placing it in the fridge overnight.

Make the Tzatziki Sauce:

  • Grate cucumber. Gather up the cucumber in a paper towel or clean dish towel and squeeze as much water out as you can. Place in small bowl.
  • Place all the other sauce ingredients in to the bowl with the cucumber and mix well.
  • Taste and salt to preference.
  • Set in fridge until ready to serve.

Make the Gyro:

  • Slice as much Seitan as you want for the amount of sandwiches you are making.
  • Slice the cucumber, tomato, and red onion.
  • In a pan on medium-high heat add a bit of oil and lightly brown the seitan slices on each side. This will only take a few minutes.
  • Warm up the flatbread.
  • Build the gyro by spreading a good amount of Tzatziki sauce on the flatbread followed by the romaine lettuce, browned seitan, cucumber, tomato, and red onion. Serve!

    This looks incredible. I have been wanting to attempt a seitan gyro for a while but have been hesitant because I think it needs a really good tzatziki sauce to make or break the dish! This one sounds delicious. Is there a specific brand of Greek style vegan yogurt you’d recommend? I look forward to trying out this recipe. I’ll have to let you know how it goes for me! 🙂
