I love using seitan as a meat substitute! It's so versatile and can be used to create delicious Italian sausages, bologna, and even seitan chicken breast for this mouth-watering vegan teriyaki chicken dish.
In this recipe, we will first coat seitan chunks in some cornstarch, then lightly sear them until they are golden and crispy. Then, they will be cooked in an amazingly flavorful homemade teriyaki sauce!

What you will need
📃Ingredients notes and substitutions
- Seitan - Use a batch of my vegan chicken breast or store-bought seitan.
- Soy sauce - Can be substituted with tamari or shoyu. Use a gluten-free brand if needed.
- Maple syrup - Feel free to substitute it with another liquid sweetener like agave or date syrup.
- Mirin- Sake is the next best substitute. You can even use dry sherry or rice vinegar but you might have to increase the amount of maple syrup used to counteract the sourness.
🔪How to make
Making teriyaki sauce - Add all seasonings needed for the sauce in a small bowl and mix well. Set aside for later use.
Preparing seitan - Add seitan cubes and cornstarch to a zip-top bag. Seal and toss the bag until seitan cubes are well coated.
Pan-frying seitan - Heat a tablespoon of oil in a well-seasoned cast-iron skillet/non-stick pan. Add seitan in one layer, and pan-fry for 2-3 minutes on both sides until golden. Remove from pan and set aside.
Putting everything together - Heat another ½ tablespoon of oil in the pan, then add ginger and garlic. Fry until aromatic. Then, add sauce along with pan-fried seitan. Cook until the sauce is thick and glossy. Serve your vegan teriyaki chicken with rice, and enjoy!
✔Helpful tips
- Do not skip cornstarch - Coating seitan in cornstarch helps them develop a crispy outer layer.
- Use a large enough pan - This is to ensure that the seitan cubes cook and crisp up properly.
- Adjusting seasoning to taste - Adjust the proportion of seasonings added to suit your taste. It is advisable to taste the dish towards the end and add more seasonings if required.
✨Variations and add-ins
Seitan - Instead of seitan, you can use other meat substitutes like pan-fried tofu or tempeh, rehydrated soy curls, or store-bought vegan chicken slices in place.
Veggies - For an extra boost of nutrients and fiber, you can add some vegetables to your vegan teriyaki chicken. Blanched broccoli, cauliflower, and carrots work particularly well. It's a good idea to double the sauce ingredients and adjust the flavor to your liking.
Teriyaki sauce - Use store-bought teriyaki sauce to make this recipe even quicker. Alternatively, you can make a batch of my vegan teriyaki sauce or spicy teriyaki sauce to be enjoyed throughout the week.
Toppings - Top your seitan teriyaki with some toasted sesame seeds or chopped green onion before serving to give them more flavor and texture.
Make it spicy - add a pinch of chili or red pepper flakes to your dish!
❄Storing suggestions
Fridge - Leftover vegan teriyaki chicken can be refrigerated for 3-4 days.
Freezer - This dish is freezable, too! Portion it out using small freezer containers, which can be frozen for a month. Thaw it overnight in the fridge, and heat it in the microwave when ready to serve. Add a splash of water if the mixture is too thick.

❔Commonly asked questions
The conventional teriyaki sauce is usually not spicy and is known for its umami and savory taste with a touch of sweetness. However, if you desire a spicier version, add a small amount of chili or red pepper flakes to the recipe.
