Ingredients You Need
Main ingredients
- Neutral oil (avocado, canola, or light olive oil)
- 1 large yellow onion, thinly sliced
- 2 cloves garlic, minced (jarred minced garlic works in a pinch)
- 12 to 16 ounces mushrooms, sliced
- Cremini or baby bella mushrooms bring deep flavor
- Add a handful of shiitakes for extra umami if you feel fancy
- 8 to 10 ounces seitan, sliced into bite-size strips
- Use a firm, plain seitan brand; I like Upton’s or WestSoy style loaves
- If you avoid gluten, swap seitan with extra-firm tofu or tempeh cubes
- 2 tablespoons vegan butter or regular butter
- 2 to 3 tablespoons all-purpose flour
- Use a 1:1 gluten free blend if needed
- 2 cups vegetable broth
- Choose a low-sodium broth so you control seasoning
- 1 tablespoon soy sauce or tamari
- 1 tablespoon Dijon mustard
- 1 teaspoon smoked paprika
- 1 teaspoon sweet paprika
- 1 teaspoon onion powder
- 1 teaspoon garlic powder
- 1 teaspoon dried thyme or 1 tablespoon fresh thyme leaves
- 1 cup unsweetened non-dairy cream or half-and-half style product
- Oat cream or cashew cream works best; avoid sweetened milks
- 1 to 2 teaspoons lemon juice or apple cider vinegar
- Salt and black pepper to taste
- Fresh parsley, chopped, for garnish
Optional flavor boosters
- 1 tablespoon nutritional yeast for extra savory depth
- 1 teaspoon white miso paste whisked into the broth
- 1 teaspoon tomato paste for a slightly richer sauce
Pantry shortcuts
- Use pre-sliced mushrooms to save chopping time.
- Use frozen chopped onions if you feel tired or short on time.
- Use jarred minced garlic and pre-made seitan strips from the refrigerated section.
What to serve it with
- 8 ounces wide egg noodles or your favorite pasta
- Or use mashed potatoes, rice, or cauliflower mash if you prefer
Equipment list
- Large skillet or wide Dutch oven
- Wooden spoon or silicone spatula
- Chef’s knife and cutting board
- Measuring cups and spoons
- Whisk
- Large pot for noodles or other starch
Tips & Mistakes
- Slice mushrooms thick so they keep texture and do not shrink into nothing.
- Brown mushrooms in a single layer and avoid crowding the pan, or they steam and turn soggy.
- Pat seitan dry before browning so it crisps slightly and soaks up sauce better.
- Use low-sodium broth so the soy sauce and mustard do not push the salt level too high.
- Add flour gradually and whisk well to avoid lumps in the stroganoff sauce.
- Keep heat at medium when you add cream so the sauce stays smooth and does not curdle.
- Taste and adjust with salt, pepper, and lemon juice at the end so flavors pop.
- Do not overcook noodles; keep them slightly firm so they hold up under the sauce.
- Cool leftovers quickly and store them in shallow containers so the sauce keeps a good texture.
How to Make Mushroom and Seitan Stroganoff Recipe
Step 1: Sauté veggies and aromatics
Heat 1 to 2 tablespoons oil in a large skillet or Dutch oven over medium heat. Add sliced onion and a pinch of salt, then cook until the onion turns soft and lightly golden, about 6 to 8 minutes. Stir in minced garlic and cook 1 minute until it smells fragrant.
Step 2: Brown the mushrooms
Add sliced mushrooms to the pan in an even layer and increase heat slightly. Let them sit for 2 to 3 minutes before stirring so they brown instead of steam. Stir and cook another 5 to 7 minutes until the mushrooms shrink a bit and develop golden edges.
Step 3: Cook the seitan
Push mushrooms and onions to one side of the pan. Add a drizzle of oil to the empty side and add seitan strips in a single layer. Cook 3 to 4 minutes, stirring once or twice, until the seitan browns and picks up some crispy spots, then mix it with the mushrooms and onions.
Step 4: Season the base
Sprinkle smoked paprika, sweet paprika, onion powder, garlic powder, and thyme over the mixture. Stir well so the spices coat the mushrooms and seitan. Cook 1 to 2 minutes so the spices toast slightly and deepen in flavor.
Step 5: Build the roux
Add vegan butter to the pan and let it melt into the vegetables and seitan. Sprinkle flour over everything and stir constantly for 1 to 2 minutes until the flour coats the mixture and no dry patches remain. The mixture should look thick and slightly pasty, which sets you up for a silky sauce.
Step 6: Add broth and flavor boosters
Slowly pour in vegetable broth while you whisk or stir constantly to avoid lumps. Add soy sauce, Dijon mustard, and any optional flavor boosters like nutritional yeast, miso, or tomato paste. Bring the mixture to a gentle simmer and cook 5 to 7 minutes until the sauce thickens and coats the back of a spoon.
Step 7: Finish with cream
Reduce heat to low and stir in the non-dairy cream. Let the stroganoff bubble gently for 3 to 5 minutes until it reaches a rich, creamy consistency. Add lemon juice, taste, and adjust with more salt and pepper as needed.
Step 8: Cook noodles and combine
While the sauce simmers, cook noodles in salted water according to package directions until just tender. Drain the noodles and either toss them directly into the stroganoff or serve the sauce over a bed of noodles. Sprinkle chopped parsley on top for freshness and color.
Variations I've Tried
I swap seitan with pan-crisped tofu cubes when I cook for gluten free friends, and the sauce still tastes rich and satisfying. I also tried a version with half mushrooms and half cauliflower florets, which gave the dish extra bite and soaked up the sauce nicely. On busy nights, I skip noodles and spoon the Mushroom and Seitan Stroganoff Recipe over frozen brown rice, which I heat in the microwave for a quick base.
How to Serve Mushroom and Seitan Stroganoff Recipe
Serve Mushroom and Seitan Stroganoff Recipe over wide egg noodles, tagliatelle, or your favorite short pasta so the sauce clings to every bite. Mashed potatoes or fluffy white rice also work great when you crave extra comfort. Add a crisp green salad or steamed green beans on the side to balance the richness. Finish with a sprinkle of fresh parsley and a twist of black pepper for a simple, restaurant-style touch.
How to store
- Store leftover Mushroom and Seitan Stroganoff Recipe in an airtight container in the fridge for up to 3 to 4 days.
- Keep noodles and sauce in separate containers if possible so the pasta does not soak up all the sauce.
- Freeze the stroganoff sauce without noodles for up to 2 months; thaw overnight in the fridge before reheating.
- Reheat gently on the stove over low to medium heat with a splash of broth or non-dairy milk, and stir often until hot and creamy again.
