Step‑by‑Step Instructions for Cozy Mushroom & Seitan Stroganoff
Step 1: Prep Ingredients
Begin by preparing your ingredients for the Cozy Mushroom & Seitan Stroganoff. Chop the onion, mince the garlic, clean and slice the mushrooms into even pieces, and thinly slice the seitan. Having everything ready will streamline your cooking process and ensure a smooth transition between steps for a delicious outcome.
Step 2: Sauté Onions
In a skillet, heat 1 tablespoon of olive oil over medium heat. Once the oil shimmers, add the chopped onions, cooking them for about 5-7 minutes. Stir occasionally until they soften and turn a lovely golden brown, enhancing the depth of flavor for your stroganoff base.
Step 3: Add Garlic
After the onions are perfectly sautéed, stir in the minced garlic, cooking for an additional 1-2 minutes. Keep an eye on it, as the garlic should become fragrant but avoid burning it, which can lead to bitterness in this flavorful dish.
Step 4: Cook Mushrooms
Raise the heat to medium-high and add the sliced mushrooms to the skillet. Sauté the mushrooms for 8-10 minutes until they release their moisture and become nicely browned. The browning process will deepen their umami flavor, a key element of the Cozy Mushroom & Seitan Stroganoff.
Step 5: Incorporate Seitan
Once the mushrooms are cooked, push them to the side of the skillet and add the thinly sliced seitan. Let it cook for 3-4 minutes, allowing it to brown slightly and absorb the flavors from the mushrooms and onions, making this dish hearty and satisfying.
Step 6: Add Flour
Sprinkle 1 tablespoon of flour over the mushroom and seitan mixture. Stir well for about 2 minutes to eliminate any raw flour taste while incorporating it into the sauce. This step is essential for achieving the creamy texture that characterizes a perfect stroganoff.
Step 7: Pour in Broth
Gradually add 1.5 cups of vegetable broth to the skillet, stirring continuously to prevent lumps. Bring the mixture to a gentle simmer, which should take approximately 3-4 minutes. This simmering process will help meld the flavors into a luscious sauce for your Cozy Mushroom & Seitan Stroganoff.
Step 8: Mix in Creaminess
Stir in 1 cup of dairy-free sour cream, along with 1 tablespoon each of Dijon mustard and soy sauce, 1 teaspoon of smoked paprika, and ½ teaspoon of thyme. Let the sauce simmer for an additional 5-7 minutes until it thickens. The blend of these ingredients is what makes this stroganoff rich and comforting.
Step 9: Cook Noodles
While the sauce simmers, prepare your egg noodles or pappardelle according to the package instructions, usually about 8-10 minutes. Drain the pasta without rinsing to keep the starch that helps the sauce adhere, ensuring a delightful experience in every bite of your Cozy Mushroom & Seitan Stroganoff.
Step 10: Combine and Serve
Finally, toss the cooked noodles with the creamy stroganoff sauce until well coated. Garnish with freshly chopped parsley for a pop of color and flavor, then serve hot. Enjoy the comforting embrace of this delicious dish that’s sure to become a staple in your home!

Expert Tips for Cozy Mushroom & Seitan Stroganoff
