Mushroom and Seitan Stroganoff Ingredients
For the Sauce
• Olive Oil – Enhances flavor and helps in sautéing; feel free to use any neutral oil if preferred.
• Onion – Builds the flavor base; shallots can be a delightful substitute for a milder taste.
• Garlic – Adds aromatic depth; fresh garlic is best for maximum flavor.
• Mushrooms (10 ounces) – Provide umami and texture; any variety will work, but cremini or button mushrooms are ideal.
• Seitan (8 ounces) – Serves as a meaty texture substitute; opt for mushrooms or tofu for gluten-free options.
• Flour (1 tablespoon) – Thickens the sauce; cornstarch or a gluten-free flour blend works for a gluten-free choice.
• Vegetable Broth (1 ½ cups) – Adds seasoning and moisture to the sauce; homemade or store-bought are both fine.
• Dairy-Free Sour Cream (1 cup) – Provides creaminess; regular sour cream works if you’re not vegan.
• Dijon Mustard (1 tablespoon) – Adds tang and depth to the dish.
• Soy Sauce or Tamari (1 tablespoon) – Enhances savory flavor; just be mindful of sodium levels.
• Smoked Paprika (1 teaspoon) and Thyme (½ teaspoon) – Contribute aroma and flavor complexity; you can substitute fresh thyme for dried.
• Salt and Pepper – Essential for seasoning the dish to your taste.
For the Pasta
• Wide Egg Noodles or Pappardelle (12 ounces) – Serves as the base of the stroganoff; gluten-free pasta can be used as an alternative.
With these ingredients, you’re one step closer to creating a delightful Mushroom and Seitan Stroganoff that will warm hearts and satisfy appetites!
Step‑by‑Step Instructions for Mushroom and Seitan Stroganoff
Step 1: Prepare the Vegetables
Start by finely chopping one medium onion and mincing three cloves of garlic. This combination will build the foundation of flavors in your Mushroom and Seitan Stroganoff. Use a sharp knife to ensure precision and safety. Set the prepared vegetables aside, ready to sauté within moments.
Step 2: Slice the Mushrooms
Clean 10 ounces of mushrooms under cold water and slice them into uniform pieces, about ¼ inch thick. This will promote even cooking and a delightful browning effect. Cremini or button mushrooms are perfect choices for their umami richness. Aim to have them ready to sauté right after onion and garlic.
Step 3: Slice the Seitan
Take 8 ounces of seitan and slice it into thin strips or bite-sized pieces. This step is crucial as it allows the seitan to absorb the flavors from the sautéed ingredients in the Mushroom and Seitan Stroganoff. Place it aside with the mushrooms, ensuring everything is prepped for a seamless cooking experience.
Step 4: Sauté Onions
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Once hot, add the chopped onion and sauté for about 5-7 minutes until it turns translucent and slightly golden. Stir frequently to avoid burning and to allow the onions to soften beautifully, releasing their sweet flavor.
Step 5: Add Garlic
Next, add the minced garlic to the skillet and sauté for an additional 1-2 minutes until fragrant. This is the perfect moment when the aroma starts enhancing the kitchen ambiance, inviting everyone to your cozy Mushroom and Seitan Stroganoff. Stir it gently to avoid burning the garlic, which can leave a bitter taste.
Step 6: Cook the Mushrooms
Increase the heat slightly, then add the sliced mushrooms to the pan. Cook them for 8-10 minutes until they are brown and their moisture evaporates. Stir occasionally to prevent sticking. Watch for the mushrooms to brown beautifully—it’s the key for delivering a rich flavor in your stroganoff.
Step 7: Brown the Seitan
Push the mushrooms to the side of the skillet and add the sliced seitan. Allow it to brown for 3-4 minutes, occasionally stirring to avoid sticking. This step enhances the meaty texture that pairs wonderfully with the creamy sauce of the Mushroom and Seitan Stroganoff.
Step 8: Thicken the Mixture
Sprinkle 1 tablespoon of flour evenly over the mushroom and seitan mixture, stirring well to coat everything. Cook for 2 minutes, allowing the flour to lightly toast, creating depth in the sauce. You can use cornstarch for a gluten-free option here.
Step 9: Add Vegetable Broth
Gradually pour in 1 ½ cups of vegetable broth while stirring continuously to combine. This will help to deglaze the pan, ensuring all those lovely browned bits mix into the sauce. Cook for around 2-3 minutes until the mixture begins to thicken, embracing the hearty elements of your Mushroom and Seitan Stroganoff.
Step 10: Incorporate Creaminess
Lower the heat and mix in 1 cup of dairy-free sour cream, 1 tablespoon of Dijon mustard, and 1 tablespoon of soy sauce or tamari. Stir in 1 teaspoon of smoked paprika and ½ teaspoon of thyme. Allow the mixture to simmer for 5-7 minutes until it thickens further, creating the creamy texture that defines your stroganoff.
Step 11: Cook the Pasta
While the stroganoff simmers, cook 12 ounces of wide egg noodles or pappardelle according to package instructions. Aim for al dente texture to hold up against the rich stroganoff sauce. After draining, do not rinse the pasta; this allows the sauce to cling better.
Step 12: Combine and Serve
Finally, combine the cooked pasta with the stroganoff sauce in the skillet, gently tossing to coat every strand. Alternatively, serve the sauce over the noodles on individual plates. Garnish with fresh parsley for a pop of color, and prepare to enjoy the comforting flavors of your Mushroom and Seitan Stroganoff!
