Mushroom and Seitan Stroganoff is a hearty, comforting dish full of rich flavors and satisfying textures. Creamy sauce, tender seitan, and meaty mushrooms come together to make a classic stroganoff that’s both warming and filling. It’s a great plant-based twist on a dish that usually stars beef, and the mushrooms add the perfect earthiness to round everything out.
I love making this stroganoff when I’m craving something cozy but still want to keep it vegan-friendly. The seitan soaks up the sauce beautifully and the mushrooms give a nice bite, making each mouthful super tasty. One friendly tip: let the sauce simmer a little longer to really deepen those flavors—it makes a big difference and is totally worth the extra patience.
The best way I’ve found to serve this meal is over a bed of soft egg noodles or creamy mashed potatoes. It’s such a crowd-pleaser and perfect for chilly evenings when you want something that feels like a warm hug on a plate. Plus, leftovers taste even better the next day, so it’s a great make-ahead meal too!
Key Ingredients & Substitutions
Seitan: This is the main protein in the dish and has a chewy, meat-like texture. If you don’t have seitan, firm tofu or tempeh can work as good substitutes.
Mushrooms: I recommend cremini mushrooms for their depth of flavor, but white button mushrooms are fine too. For a richer taste, try adding shiitake or portobello slices.
Flour: This helps thicken the sauce. You can replace all-purpose flour with gluten-free flour or cornstarch if you want a gluten-free version. Just mix cornstarch with a bit of water before adding.
Coconut Milk or Vegan Sour Cream: Both bring creaminess and tang. Coconut milk adds a slightly sweet note, while vegan sour cream offers a more traditional tangy taste. Choose depending on your preference.
How Can I Get the Sauce Thick and Creamy Without Lumps?
The key to a smooth stroganoff sauce is to cook the flour well and add liquids slowly. Here’s how I do it:
- After cooking mushrooms, sprinkle the flour evenly and stir well, cooking for about 1 minute to avoid a raw flour taste.
- Add vegetable broth gradually while stirring constantly. This stops lumps from forming.
- Simmer gently after adding coconut milk or vegan sour cream. Stir occasionally until the sauce thickens nicely.
Patience during the simmering helps the flavors blend and the sauce reach just the right creamy consistency.
Equipment You’ll Need
- Large skillet – perfect for cooking seitan and mushrooms evenly in one pan.
- Spoon or spatula – great for stirring the sauce without scratching your pan.
- Measuring cups and spoons – help you add the right amount of broth, spices, and coconut milk.
- Sharp knife and cutting board – to slice mushrooms and chop onions safely and easily.
- Whisk – useful to mix flour into the sauce smoothly and prevent lumps.
Flavor Variations & Add-Ins
- Swap seitan for marinated tofu for a softer texture and milder flavor.
- Add spinach or kale near the end for a fresh, green boost and extra nutrients.
- Include smoked paprika for a smoky twist that deepens the sauce’s flavor.
- Mix in caramelized onions to add sweetness and richer depth to the dish.

How Much Time Will You Need?
This recipe takes about 10 minutes to prep and roughly 25 minutes to cook, making a total of around 35 minutes. It’s a quick, satisfying meal that’s ready in under an hour!
Step-by-Step Instructions:
1. Cook the Seitan:
Heat olive oil or vegan butter in a large skillet over medium heat. Add the seitan cubes and cook, stirring occasionally, until they’re nicely browned on all sides, about 5 minutes. Remove and set aside.
2. Sauté Onions and Garlic:
In the same skillet, add the chopped onion. Cook for about 4 minutes until soft and translucent. Add the minced garlic and sauté for another minute until fragrant.
3. Cook the Mushrooms:
Add the sliced mushrooms to the pan. Cook for 7 to 8 minutes, stirring often, until they release their moisture and become golden brown.
4. Make the Sauce Base:
Sprinkle the flour over the mushrooms and stir well to coat everything evenly. Cook for about 1 minute to avoid any raw flour taste. Slowly pour in the vegetable broth, stirring constantly to avoid lumps. Add the soy sauce, smoked paprika, and dried thyme. Stir to combine.
5. Finish the Stroganoff:
Return the browned seitan to the skillet. Lower the heat to a gentle simmer and stir in the coconut milk or vegan sour cream. Cook for 5 to 7 minutes, stirring occasionally, until the sauce thickens and becomes creamy. Season with salt and black pepper to taste.
6. Serve and Garnish:
Serve the stroganoff hot over cooked rotini pasta, egg noodles, or rice. Sprinkle freshly chopped parsley on top for a fresh touch.
Can I Use Frozen Seitan for This Stroganoff?
Yes, you can use frozen seitan! Just make sure to thaw it completely in the fridge overnight before cooking. Pat it dry with a paper towel to remove any excess moisture, which helps with browning.
What Can I Substitute for Coconut Milk or Vegan Sour Cream?
If you don’t have coconut milk or vegan sour cream, plain cashew cream or unsweetened almond milk mixed with a tablespoon of lemon juice makes a great substitute to keep the sauce creamy and slightly tangy.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove over low heat, stirring often. You may want to add a splash of vegetable broth or plant milk to loosen the sauce if it thickens too much.
Can I Make This Recipe Gluten-Free?
Absolutely! Use gluten-free flour or cornstarch instead of all-purpose flour to thicken the sauce. Also, choose gluten-free tamari instead of regular soy sauce to keep the dish fully gluten-free.
