Mushroom and Seitan Stroganoff Ingredients
For the Sauce
• Olive Oil – Adds richness and helps sauté vegetables; substitute with vegetable oil if needed.
• Onion – Provides a sweet and aromatic base; yellow or white onions work best for this recipe.
• Garlic – Enhances flavor with its aromatic properties; fresh garlic is recommended for the best taste.
• Mushrooms (10 ounces) – The key component providing umami flavor; slice evenly for uniform cooking and consider portobello or shiitake as substitutes.
• Seitan (8 ounces) – Offers a meaty texture; slice into strips to mimic traditional beef; tempeh or mushrooms make great gluten-free alternatives.
• Flour (1 tablespoon) – Helps thicken the sauce; use a gluten-free flour blend if necessary for a gluten-free Mushroom and Seitan Stroganoff.
• Vegetable Broth (1.5 cups) – Forms the base of the sauce; homemade broth or water can be used as a convenient alternative.

• Dijon Mustard (1 tablespoon) – Provides tanginess; yellow mustard can serve as a substitute if you don’t have Dijon.
• Soy Sauce or Tamari (1 tablespoon) – Adds depth and saltiness; tamari is a great gluten-free option.
• Smoked Paprika (1 teaspoon) – Contributes smokiness; you can use regular paprika if needed.
• Thyme (½ teaspoon) – Adds a herbal note; fresh thyme really enhances the flavors if available.
• Salt and Pepper – For seasoning; adjust to taste as you cook and taste the sauce.
For Serving

Step‑by‑Step Instructions for Mushroom and Seitan Stroganoff
Step 1: Preheat the Skillet
Begin by preheating a large skillet over medium heat. Add a generous splash of olive oil, allowing it to heat for about 1-2 minutes until shimmering. The oil should be hot but not smoking, ready to sauté the onions to form a sweet, aromatic base for your Mushroom and Seitan Stroganoff.
Step 2: Sauté the Onions
Add chopped onion to the skillet, stirring frequently for 5-7 minutes until they become translucent and slightly golden. This is a key step that develops flavor, so look for a soft and tender texture. Once ready, the onions will release a delightful aroma, setting the stage for the rest of your dish.
Step 3: Add Garlic
Stir in minced garlic and let it sauté for 1-2 minutes, stirring constantly. You’ll know it’s done when the garlic is fragrant and golden, enhancing the flavor of the base. Be careful not to burn it, as burnt garlic can turn bitter and impact the taste of your Mushroom and Seitan Stroganoff.
Step 4: Cook the Mushrooms
Raise the heat to medium-high and add your sliced mushrooms. Cook for 8-10 minutes, stirring occasionally, until the mushrooms have released their liquid and turned a deep golden brown. This browning process brings out their rich umami flavor, essential for the characteristic depth of your stroganoff.
Step 5: Add the Seitan
Push the mushrooms to one side of the skillet and add the sliced seitan on the other. Allow it to cook for 3-4 minutes, stirring gently, until it’s slightly browned. This step adds a hearty, meaty texture to your Mushroom and Seitan Stroganoff, mimicking the traditional version with beef.
Step 6: Incorporate the Flour
Sprinkle the flour evenly over the mushroom and seitan mixture, stirring to combine. Cook for about 2 minutes, allowing the flour to absorb the moisture and cook out its raw taste. This will help thicken your stroganoff sauce beautifully as you proceed with the recipe.
Step 7: Add the Broth
Gradually pour in the vegetable broth, stirring continuously to avoid lumps. Let it simmer gently for about 3-5 minutes until the mixture thickens slightly and the flavors meld together. Take a moment to appreciate the rich aroma wafting through your kitchen, as your Mushroom and Seitan Stroganoff begins to take shape.
Step 8: Stir in the Creamy Ingredients
Mix in the dairy-free sour cream, Dijon mustard, soy sauce, smoked paprika, and thyme. Stir well to combine and simmer for another 5-7 minutes, until the sauce is creamy and has thickened to your liking. Tasting along the way helps ensure the flavors are just right.
Step 9: Cook the Pasta
While your sauce simmers, bring a pot of salted water to a boil and add your favorite pasta. Cook according to package instructions until al dente. Once ready, drain the pasta without rinsing to allow the sauce to cling better when you serve this delightful Mushroom and Seitan Stroganoff.
Step 10: Combine and Serve
Finally, combine the cooked pasta with the stroganoff sauce in the skillet, tossing gently to coat. For a stunning presentation, serve it in bowls, garnished with fresh parsley and lemon wedges for a zesty finish. Enjoy the comforting flavors and textures of your homemade dish!

Expert Tips for Mushroom and Seitan Stroganoff
Perfectly Sautéed Mushrooms: Cook mushrooms until all moisture evaporates for enhanced umami flavor. This prevents a watery sauce in your Mushroom and Seitan Stroganoff.
Thick Sauce Consistency: If the sauce is too thin, gradually add more vegetable broth while simmering until you reach your desired thickness, ensuring a creamy finish.
Seasoning Adjustment: Always taste your sauce before serving. If it feels bland, a pinch of salt or a splash of lemon juice can brighten the flavors considerably.
Pasta Cooked Right: Cook your pasta al dente so it holds up against the rich stroganoff sauce. This ensures each bite remains delightful and satisfying.
