Mushroom and Seitan Stroganoff is a hearty, comforting dish that’s perfect when you want something warm and satisfying. The tender seitan adds a wonderful chewy texture that pairs beautifully with the creamy mushroom sauce. Think rich flavors from sautéed mushrooms and onions, all coated in a smooth, tangy sauce that hugs every bite.
I love making this stroganoff when I’m craving something cozy but want to keep it meat-free. The seitan soaks up all the flavors, making each forkful taste deliciously rich. A little tip I’ve learned is to use a mix of mushrooms—like cremini and shiitake—to add extra depth and earthiness. It really takes the dish to the next level!
When I serve this, I usually pile it over egg noodles or creamy mashed potatoes. It’s one of those meals that feels like a warm hug on a chilly evening. Plus, it’s great for sharing with friends because it’s filling, tasty, and doesn’t take too long to make. This stroganoff always gets compliments, and I find myself going back for seconds every time!
Key Ingredients & Substitutions
Seitan: This is the star protein here. It gives a chewy, meaty texture that works perfectly in stroganoff. If you can’t find seitan, try firm tofu or tempeh as a good substitute.
Mushrooms: Cremini or button mushrooms are great fresh options. Mixing in shiitake or portobello mushrooms adds extra flavor and depth. For a quick fix, use pre-sliced mushrooms.
Vegan Sour Cream or Yogurt: This gives the sauce its creamy tang. Coconut-based sour cream or plain unsweetened vegan yogurt both work well. Avoid dairy if you want to keep it vegan.
Vegetable Broth: Use a good-quality broth for the best flavor. If you don’t have any, water with a splash of soy sauce or tamari makes a handy substitute.
How Can I Get a Thick, Creamy Sauce Without Lumps?
The secret is in slowly adding the liquid and stirring well after sprinkling the flour onto the cooked seitan and mushrooms. This helps avoid clumps and makes the sauce smooth.
- After browning, sprinkle the flour evenly and stir for 1–2 minutes to cook out raw flour taste.
- Pour in the vegetable broth bit by bit, stirring constantly as the sauce forms and thickens.
- Once thickened, lower the heat before adding the vegan sour cream and mustard, stirring gently to keep the sauce creamy without curdling.
Patience during this stage really pays off in a silky sauce that coats the noodles and seitan beautifully.
Equipment You’ll Need
- Large skillet – big enough to cook seitan and mushrooms evenly without crowding.
- Wooden spoon or silicone spatula – great for stirring without scratching your pan.
- Medium pot – perfect for boiling your noodles or pasta.
- Colander – to drain your cooked pasta easily.
- Measuring cups and spoons – help you keep your sauce and seasoning balanced.
Flavor Variations & Add-Ins
- Swap seitan for tempeh or firm tofu if you want a milder flavor or a soy-based option.
- Add a splash of white wine to the sauce for a bit of brightness and depth.
- Mix in sautéed spinach or kale near the end for extra greens and nutrients.
- Use smoked paprika or a pinch of cayenne to add smoky heat when you want more spice.

How Much Time Will You Need?
This recipe takes about 10 minutes prep time and 25 minutes cooking time. In total, you’ll need around 35 minutes to enjoy this creamy, delicious stroganoff.
Step-by-Step Instructions:
1. Prepare the Pasta:
Cook the rotini or egg noodles according to the package directions until they’re al dente. Drain them and set aside while you make the stroganoff sauce.
2. Cook the Aromatics and Mushrooms:
In a large skillet, warm the olive oil or vegan butter over medium heat. Toss in the chopped onion and sauté for 3–4 minutes until translucent and fragrant. Then add the minced garlic and sliced mushrooms. Cook this mixture for about 7–8 minutes, stirring occasionally, until mushrooms have released their moisture and start to turn golden brown.
3. Add Seitan and Spices:
Stir in the seitan pieces and cook for another 3–4 minutes, letting them brown just a little. Then sprinkle the flour evenly over the skillet contents. Stir well to coat everything with flour and cook for 1–2 minutes to remove the raw flavor.
4. Create the Sauce:
Slowly pour in the vegetable broth, stirring constantly to prevent lumps. Next, add soy sauce or tamari, smoked paprika, black pepper, thyme if you’re using it, and salt to taste. Bring the mixture to a gentle simmer and let it cook for about 5 minutes. This will help the sauce thicken and for all the lovely flavors to blend together.
5. Finish the Sauce:
Lower the heat to low. Stir in the vegan sour cream and Dijon mustard until the sauce is smooth and creamy. Heat through gently—be careful not to let the sauce boil as this can cause curdling.
6. Combine and Serve:
Place the cooked pasta on plates or a serving dish. Spoon your mushroom and seitan stroganoff sauce generously over the noodles. Garnish with freshly chopped parsley for a fresh touch.
Enjoy your warm, comforting stroganoff with a side of steamed greens or a light salad to complete the meal!
Can I Use Frozen Seitan for This Recipe?
Yes, you can use frozen seitan! Just thaw it completely in the refrigerator overnight or use the defrost setting on your microwave. Pat it dry before cooking to avoid excess moisture in the pan.
What Can I Substitute for Vegan Sour Cream?
If you don’t have vegan sour cream, plain unsweetened vegan yogurt or even a splash of coconut cream works well. Just add it at the end of cooking and stir gently to keep the sauce creamy.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. When reheating, warm gently on the stove over low heat, stirring occasionally, and add a splash of vegetable broth if the sauce seems too thick.
Can I Make This Recipe Gluten-Free?
To make it gluten-free, use gluten-free flour for thickening and make sure the seitan is replaced with a gluten-free protein like firm tofu or tempeh. Also, choose gluten-free pasta to keep it safe for gluten-sensitive diets.
