Ingredients You’ll Need

You’ll be amazed at how a handful of simple yet thoughtfully chosen ingredients can come together to create something truly spectacular. Each component of this Mushroom and Seitan Stroganoff plays a starring role, contributing essential layers of taste, richness, and irresistible aroma.

• Olive oil: Use this as the base for sautéing your vegetables to infuse everything with richness from the start.
• Onion: Finely chopped onion brings an essential sweetness and a foundation of flavor that carries through the entire dish.
• Garlic: Minced garlic offers an inviting, aromatic note that mingles beautifully with the mushrooms and seitan.
• Cremini or button mushrooms: Sliced and sautéed, these mushrooms provide umami, juiciness, and a meaty texture—don’t be shy with them!
• Seitan: Sliced into strips, this wheat-based protein soaks up all the flavors while adding hearty chewiness, making the stroganoff extra satisfying.
• All-purpose flour: A bit of flour thickens the sauce, ensuring that velvety, classic stroganoff consistency.
• Vegetable broth: Pour it in gradually to deglaze the pan, building the base of your luscious sauce.
• Dairy-free sour cream (or regular): This creamy addition delivers the luscious tang and silkiness stroganoff is famous for—go vegan or traditional as you wish.
• Dijon mustard: Just a spoonful brightens and deepens the flavor profile of the sauce.
• Soy sauce or tamari: Adds umami and complexity; use tamari for a gluten-free option.
• Smoked paprika: Lends a touch of earthiness and subtle smokiness that hints at the traditional flavors of classic stroganoff.
• Thyme (dried or fresh): This herb brings a gentle woodsy note that complements mushrooms beautifully.
• Salt and pepper: Adjust to taste at the end for perfectly seasoned comfort food.
• Fresh parsley: Chopped parsley tossed on top adds color and a pop of freshness to your finished dish.
• Wide egg noodles or pappardelle: Serve your stooganoff over these satisfyingly broad noodles for a traditional touch; pick vegan pasta if needed.
• Lemon wedges (optional): A squeeze at the table brightens the flavors and adds zing, if you like!

How to Make Mushroom and Seitan Stroganoff

Step 1: Prep Your Ingredients

Start by gathering all your veggies and proteins: finely chop the onion, mince the garlic, wipe clean and slice the mushrooms, and cut your seitan into thin, beef-like strips. Prepping everything ahead will make the cooking process smooth and help the flavors meld together beautifully in your Mushroom and Seitan Stroganoff.

Step 2: Sauté the Onion and Garlic

Heat the olive oil in a large skillet over medium heat. Add the chopped onion and cook, stirring occasionally, for five to seven minutes—watch as it turns translucent and starts to develop a gorgeous caramelized edge. Toss in the minced garlic and cook for another minute or two, just until fragrant.

Step 3: Add the Mushrooms

Crank up the heat slightly to medium-high, then add all those sliced mushrooms. They’ll initially release lots of moisture, but keep cooking—and stirring—until that liquid disappears and the mushrooms take on a deep golden-brown color. This step can take about eight to ten minutes and adds big flavor to your Mushroom and Seitan Stroganoff.

Step 4: Brown the Seitan

With your mushrooms browned, push them to the sides of the pan to make a little well in the center. If you need, add a splash more olive oil, then add the seitan strips. Let them sear for three to four minutes, stirring occasionally so they get a little crispy and soak up all the goodness from the pan.

Step 5: Build the Stroganoff Sauce

Sprinkle the flour over the seitan and mushrooms, then stir for about two minutes so it cooks through and loses that raw taste. Now, slowly pour in the vegetable broth, stirring constantly to eliminate lumps. Stir in the dairy-free (or regular) sour cream, Dijon mustard, soy sauce or tamari, smoked paprika, and thyme. Let this gorgeous sauce simmer gently for five to seven minutes, thickening to glossy perfection.

Step 6: Season and Adjust

Taste your Mushroom and Seitan Stroganoff at this stage—season with salt and pepper as needed. If the sauce feels too thick, just stir in a splash of veggie broth or water to get your ideal consistency. You want it creamy enough to coat the noodles without feeling heavy.

Step 7: Prepare and Serve the Pasta

While the sauce is simmering, cook your noodles or pappardelle in a big pot of salted boiling water until just al dente. Drain them well. You can either mix the noodles straight into the stroganoff sauce for a cozy, homestyle dish or serve the sauce spooned luxuriously over a neat mound of pasta for a more elegant presentation.

How to Serve Mushroom and Seitan Stroganoff

Garnishes

Finish your Mushroom and Seitan Stroganoff with a generous sprinkle of freshly chopped parsley for color, aroma, and a burst of freshness. If you love a little brightness, squeeze a lemon wedge over each portion right before serving—it perks up the savory flavors beautifully.

Side Dishes

This stroganoff is plenty hearty on its own, but sides can elevate the meal to another level. Serve it with a crisp green salad, steamed green beans, or roasted asparagus to balance out the richness of the sauce. A slice of crusty bread also makes a lovely companion for mopping up every last drop!

Creative Ways to Present

If you’re entertaining or just want something extra special, try plating Mushroom and Seitan Stroganoff in individual shallow bowls over a twirl of noodles, topped with fresh herbs and a drizzle of extra virgin olive oil. Or, spoon the stroganoff into baked potato halves or use it as a filling for a savory pie for a showstopping twist.

Make Ahead and Storage

Storing Leftovers

Leftover Mushroom and Seitan Stroganoff can be stored in an airtight container in the refrigerator for up to three days. The sauce may thicken as it sits, but the flavors actually deepen, making for some seriously crave-worthy leftovers.

Freezing

This dish freezes well! Cool your stroganoff completely and transfer it to a freezer-safe container. It’ll keep in the freezer for up to two months. For best texture, freeze the sauce and the pasta separately if you plan to make extra for future meals.

Reheating

When you’re ready to enjoy your Mushroom and Seitan Stroganoff again, gently reheat it on the stovetop over low heat, adding a splash of vegetable broth or water to loosen up the sauce if needed. Microwave reheating also works in a pinch—just heat in intervals and stir frequently for even warming.

FAQs

Can I use a different type of mushroom?

Absolutely! While cremini or button mushrooms work beautifully, you can experiment with shiitake or portobello for an even deeper, earthier flavor. Just make sure to slice them evenly for consistent cooking.

Is there a gluten-free option for this stroganoff?

Yes, you can make Mushroom and Seitan Stroganoff gluten-free by swapping the seitan for sautéed tofu strips or your favorite gluten-free protein. Use tamari in place of soy sauce, and make sure to select gluten-free noodles.

What can I use instead of sour cream?

If you don’t have sour cream handy (dairy-free or otherwise), plain unsweetened yogurt or a thick cashew cream works as a substitute. Just be sure it’s not too runny, so your sauce stays nice and luscious.

Can I prepare this recipe in advance for entertaining?

Absolutely! Mushroom and Seitan Stroganoff can easily be made ahead up to a day in advance. Store the sauce and noodles separately, then combine and reheat just before serving for the best texture and appearance.

Will the seitan become chewy if cooked ahead of time?

If you store it properly and reheat gently with a little extra broth, the seitan should stay pleasantly tender. Avoid overheating, and your Mushroom and Seitan Stroganoff will be just as delicious as when freshly made!
