Ingredients You Need

Mushrooms

1 pound cremini mushrooms, sliced (also labeled “baby bella”; they bring great flavor and texture)
8 ounces white button mushrooms, sliced (milder flavor that balances the cremini)
Optional: 4 ounces shiitake mushrooms, stems removed and caps sliced (boosts deep, savory flavor)

You can use all one type of mushroom if that’s what you have. I like a mix because it adds more flavor and texture.

Aromatics

1 medium yellow onion, finely diced
3–4 cloves garlic, minced
1 tablespoon fresh thyme leaves (or 1 teaspoon dried thyme)
1 tablespoon fresh parsley, chopped (plus more for garnish)

Sauce Base

3 tablespoons unsalted butter (or vegan butter if you want a dairy-free version)
2 tablespoons olive oil
3 tablespoons all-purpose flour (or a 1:1 gluten-free flour blend)
2 cups vegetable broth (low-sodium if possible; Better Than Bouillon veggie base works great)
1 tablespoon soy sauce or tamari (adds umami and color)
1 teaspoon Dijon mustard
1 teaspoon smoked paprika or sweet paprika (smoked gives a deeper flavor)
½ teaspoon onion powder (nice shortcut for extra savoriness)
½ teaspoon fine sea salt, plus more to taste
½ teaspoon black pepper, freshly ground

Creamy Element

Pick one of these, based on your preference:

1 cup full-fat sour cream
or 1 cup plain Greek yogurt (whole milk; adds tang and protein)
or 1 cup cashew cream (for vegan: blend ¾ cup soaked cashews with ½–¾ cup water)
or 1 cup unsweetened thick oat cream or coconut cream (use coconut only if you enjoy a hint of coconut)

Pasta or Base

12 ounces egg noodles, wide (classic choice)
or 12 ounces fettuccine, rotini, or other pasta
or 3 cups cooked rice, mashed potatoes, or cauliflower mash if you want a lower-carb base

Cook the base separately while the sauce simmers. Keep it hot so the sauce coats it nicely.

Optional Add-Ins

½ cup frozen peas (no need to thaw; toss in near the end)
½ cup baby spinach or kale, chopped
¼ cup grated Parmesan or pecorino (skip or use vegan parm if dairy-free)
Pinch of red pepper flakes for gentle heat

Equipment List

Large, wide skillet or sauté pan (10–12 inch; a heavy pan browns mushrooms better)
Large pot for pasta or rice
Cutting board and sharp knife
Wooden spoon or silicone spatula
Measuring cups and spoons
Whisk
Small bowl for tempering sour cream or yogurt

Quick Tips & substitutions

Slice mushrooms thick so they keep meaty texture and don’t vanish into the sauce.
Pat mushrooms dry before cooking so they brown instead of steaming.
Use tamari instead of soy sauce if you need a gluten-free option.
Swap butter with olive oil or vegan butter to keep the Vegetarian Mushroom Stroganoff Recipe dairy-free.
Use cashew cream or thick oat cream instead of sour cream for a vegan version.
Choose a 1:1 gluten-free flour blend and gluten-free pasta to keep everything gluten-free.
Stir sour cream or yogurt into a small amount of warm sauce first so it doesn’t curdle.
Cook pasta just to al dente so it holds up under the creamy sauce.
Taste and adjust salt at the end because broths and soy sauce vary in saltiness.
Add a splash of extra broth if the sauce thickens too much while it sits.

How to Make Vegetarian Mushroom Stroganoff Recipe

Step 1: Prep the Ingredients

Wash and dry the mushrooms, then slice them about ¼-inch thick. Dice the onion, mince the garlic, and chop the herbs. Measure out the flour, broth, soy sauce, mustard, and spices so everything stands ready to go.

Cook your pasta or base according to package directions. Drain it, toss with a tiny drizzle of olive oil to prevent sticking, and keep it warm.

Step 2: Brown the Mushrooms

Heat a large skillet over medium-high heat. Add 1 tablespoon olive oil and 1 tablespoon butter. When the butter melts and looks foamy, add about half the mushrooms in a single layer.

Let the mushrooms sit for 3–4 minutes without stirring so they brown on one side. Stir and cook another 3–4 minutes until they shrink and deepen in color, then move them to a bowl. Repeat with the remaining mushrooms, adding more oil or butter if the pan looks dry.

Step 3: Cook the Aromatics

Turn the heat down to medium. Add the remaining butter and olive oil to the skillet. Add the diced onion and cook 4–5 minutes until it turns soft and golden at the edges.

Stir in the garlic and thyme and cook about 30 seconds until fragrant. Add the browned mushrooms back to the pan and stir everything together.

Step 4: Build the Roux

Sprinkle the flour evenly over the mushroom mixture. Stir constantly for 1–2 minutes so the flour coats the vegetables and cooks. The mixture will look thick and a bit pasty, and that means it works correctly.

Whisk in the smoked paprika, onion powder, salt, and black pepper. Stir to coat the mushrooms with the spices.

Step 5: Add Broth and Seasonings

Slowly pour in the vegetable broth while you whisk or stir. Add about ½ cup at a time and stir until smooth before adding more. This step keeps lumps away and gives you a silky sauce.

Stir in the soy sauce and Dijon mustard. Bring the mixture to a gentle simmer and cook 5–7 minutes, stirring often, until the sauce thickens and coats the back of a spoon.

Step 6: Make It Creamy

Turn the heat down to low. Scoop about ½ cup of the hot mushroom sauce into a small bowl. Whisk in your sour cream, yogurt, cashew cream, or other creamy base until smooth.

Pour this creamy mixture back into the skillet while you stir. Keep the heat low and cook 2–3 minutes more, stirring often, until the Vegetarian Mushroom Stroganoff Recipe looks glossy and creamy. Do not let it boil, since high heat can cause dairy to split.

Taste and adjust salt and pepper. Add a pinch more smoked paprika or mustard if you want deeper flavor.

Step 7: Add Optional Veggies and Cheese

If you use peas or spinach, stir them into the sauce now. Cook 1–2 minutes until the peas heat through and the greens wilt. Stir in grated Parmesan if you use it, and let it melt into the sauce.

Sprinkle in chopped parsley for freshness. The sauce should look thick but still pourable; add a splash of broth if it feels too thick.

Step 8: Combine With Pasta or Base

Add the cooked noodles or other base directly into the skillet. Toss gently until every strand or grain gets coated in the mushroom stroganoff sauce. If the mixture looks tight, loosen it with a bit more broth or a spoonful of the pasta cooking water if you saved some.

Serve the Vegetarian Mushroom Stroganoff Recipe hot, with extra parsley and black pepper on top. Take a second to admire that creamy goodness before everyone devours it.

Recipe Variations

Gluten-free: Use gluten-free pasta, tamari instead of soy sauce, and a 1:1 gluten-free flour blend.
Vegan: Use olive oil or vegan butter, cashew cream or oat cream, and skip Parmesan or use vegan Parmesan.
Low carb: Serve the sauce over cauliflower rice, zucchini noodles, or mashed cauliflower instead of pasta.
Extra protein: Add cooked lentils, chickpeas, or cubed tofu to the sauce near the end.
More veggies: Stir in spinach, kale, peas, or steamed broccoli florets.
Extra smoky: Use smoked paprika and a dash of liquid smoke.
Spicy version: Add red pepper flakes or a bit of hot sauce to taste.

Ways to Serve Vegetarian Mushroom Stroganoff Recipe

Spoon over wide egg noodles or fettuccine for a classic stroganoff feel.
Serve on top of fluffy mashed potatoes for maximum comfort.
Pair with brown rice, quinoa, or farro for a heartier, higher-fiber meal.
Ladle over cauliflower mash or zucchini noodles for a lighter option.
Add a side of roasted green beans, steamed broccoli, or a crisp green salad.
Top with extra herbs, a dollop of sour cream or yogurt, and freshly cracked black pepper.

Storage Success

Store leftover Vegetarian Mushroom 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 vegetable broth or water when you reheat it. Warm it gently on the stove over low heat or in the microwave in short bursts, stirring between each burst. If you use a dairy base, keep the heat low so the sauce stays creamy and smooth.
