Ingredients You Need

Main ingredients

• 2 tablespoons olive oil or vegan butter
• 1 medium yellow onion, finely chopped
• 3 cloves garlic, minced
• 12 ounces cremini or baby bella mushrooms, sliced (white button mushrooms also work)
• 8 ounces seitan, sliced into thin strips or bite-size pieces
  • Use a neutral-flavor or “chicken-style” seitan for the best result.
• 2 tablespoons soy sauce or tamari (tamari works well for gluten-free needs)
• 1 tablespoon Dijon mustard
• 1 teaspoon smoked paprika
• 1 teaspoon sweet paprika
• ½ teaspoon dried thyme or 1 teaspoon fresh thyme leaves
• ¼ teaspoon black pepper, plus more to taste
• ½ teaspoon fine sea salt, plus more to taste

Sauce ingredients

• 2 tablespoons all-purpose flour
  • Use cornstarch or arrowroot for gluten-free needs (see tips section).
• 1 ½ cups vegetable broth
  • Choose a low-sodium brand so you control the salt.
• ½ cup unsweetened non-dairy milk (soy or oat milk give the creamiest texture)
• ½ cup vegan sour cream or thick unsweetened coconut yogurt
  • Kite Hill, Tofutti, or similar brands work well.
• 1 tablespoon nutritional yeast (optional, for extra savory flavor)
• 1 teaspoon lemon juice or apple cider vinegar, to brighten the sauce

Pasta or base

• 10–12 ounces wide egg-free noodles, fettuccine, or rotini
  • Whole wheat or chickpea pasta both hold up nicely.
• 1–2 tablespoons pasta cooking water, as needed to loosen the sauce

Garnishes

• 2 tablespoons chopped fresh parsley or chives
• Extra black pepper
• A squeeze of lemon juice, if you like a brighter finish

Pantry shortcuts and notes

• Use pre-sliced mushrooms to save chopping time.
• Use pre-cooked seitan strips or “seitan tips” from the refrigerated section.
• Use minced garlic from a jar in a pinch, though fresh garlic tastes better.
• Use boxed vegetable broth and shelf-stable non-dairy milk to keep this recipe pantry-friendly.

Equipment list

• Large deep skillet or sauté pan (10–12 inch)
• Medium pot for boiling pasta
• Cutting board and sharp knife
• Wooden spoon or spatula
• Measuring cups and spoons
• Whisk

Quick Tips & substitutions

• Slice mushrooms thick so they keep a meaty texture and do not shrink into nothing.
• Brown the mushrooms and seitan well before you add liquids to build deep flavor.
• Use tamari instead of soy sauce if you avoid gluten.
• Swap all-purpose flour with 1 tablespoon cornstarch mixed into cold broth for a gluten-free sauce.
• Use coconut cream instead of vegan sour cream if you want an extra rich stroganoff.
• Add a splash of lemon juice at the end to balance the richness.
• Use any short pasta, mashed potatoes, or rice as the base, depending on what you have.
• Taste and adjust salt at the very end, since soy sauce and broth both contain sodium.

How to Make Mushroom and Seitan Stroganoff Recipe

Step 1: Cook the pasta or base

1. Bring a large pot of salted water to a boil.
2. Add your pasta and cook until just al dente, according to package directions.
3. Reserve 1–2 tablespoons of the starchy cooking water, then drain the pasta.
4. Keep the pasta warm and toss it with a tiny drizzle of olive oil so it does not stick.

Step 2: Sauté onions, mushrooms, and seitan

1. Heat the olive oil or vegan butter in a large skillet over medium-high heat.

2. Add the chopped onion and cook until it turns translucent and lightly golden, about 4–5 minutes.

3. Stir in the garlic and cook 30 seconds, until fragrant.

4. Add the sliced mushrooms in an even layer.

5. Let them cook without stirring for 2–3 minutes so they brown.

6. Stir and continue to cook until the mushrooms release their liquid and turn deep golden, about 5–7 minutes more.

7. Add the seitan strips to the skillet.

8. Cook 3–4 minutes, stirring occasionally, until the edges brown and crisp slightly.

Step 3: Season and build flavor

1. Sprinkle in the smoked paprika, sweet paprika, thyme, black pepper, and salt.
2. Stir well so the spices coat the mushrooms and seitan.
3. Add the soy sauce and Dijon mustard, then stir again and cook 1–2 minutes so everything melds.

Step 4: Thicken the base

1. Reduce the heat to medium.

2. Sprinkle the flour evenly over the mushroom and seitan mixture.

3. Stir constantly for 1–2 minutes so the flour coats everything and loses its raw taste.

4. Slowly pour in the vegetable broth while you whisk or stir, breaking up any lumps.

5. Add the non-dairy milk and nutritional yeast (if using), and stir again.

6. Bring the mixture to a gentle simmer and cook 4–5 minutes, until the sauce thickens and coats the back of a spoon.

Step 5: Finish the creamy stroganoff sauce

1. Turn the heat to low.
2. Stir in the vegan sour cream until the sauce turns silky and uniform.
3. Add the lemon juice and taste the sauce.
4. Adjust with more salt, pepper, or a pinch more smoked paprika if you want extra depth.

Step 6: Combine with pasta and serve

1. Add the cooked pasta directly into the skillet with the stroganoff sauce.
2. Toss gently until the noodles soak up the sauce and everything looks glossy.
3. If the sauce feels too thick, add a splash of reserved pasta water until it reaches your ideal consistency.
4. Serve hot, topped with chopped parsley or chives and extra black pepper.

Recipe Variations

• Gluten-free version: Use gluten-free pasta, tamari instead of soy sauce, and cornstarch instead of flour.
• Vegan and nut-free: Use nut-free non-dairy milk like oat or soy and a soy-based sour cream.
• Low-carb option: Serve the stroganoff sauce over zucchini noodles, spaghetti squash, or steamed cauliflower instead of pasta.
• Extra protein: Add cooked lentils or chickpeas along with the seitan for a heartier bowl.
• More veggies: Stir in spinach, kale, or peas during the last 2–3 minutes of cooking.
• Spicy twist: Add red pepper flakes or a pinch of cayenne with the other spices.

Ways to Serve Mushroom and Seitan Stroganoff Recipe

• Spoon over wide noodles, mashed potatoes, or fluffy rice.
• Serve with a crisp green salad and lemony vinaigrette.
• Pair with roasted broccoli, green beans, or asparagus on the side.
• Top with extra herbs and a squeeze of lemon for brightness.
• Serve in a bowl with crusty bread or garlic toast to soak up the sauce.

Storage Success

Store leftover Mushroom and Seitan Stroganoff Recipe in an airtight container in the fridge for up to 3–4 days. The sauce thickens as it chills, so stir in a splash of broth or non-dairy milk when you reheat it on the stove or in the microwave. Stir halfway through reheating so the sauce turns smooth again. You can freeze the sauce without pasta for up to 2 months, then thaw in the fridge and reheat gently before serving over fresh noodles or rice.
