Instructions

Step 1: Cook the Noodles
Bring a large pot of salted water to a boil. Cook egg noodles according to package instructions. Drain and set aside.
Step 2: Sauté the Onions
While noodles cook, heat butter and olive oil in a large skillet over medium heat. Add sliced onions and sauté for 5–6 minutes, until softened and lightly golden.
Step 3: Cook the Mushrooms
Add mushrooms and cook for another 7–8 minutes, stirring occasionally, until mushrooms are browned and most liquid has evaporated.
Step 4: Add Garlic
Stir in garlic and cook for 1 minute, until fragrant.
Step 5: Add Flour and Paprika
Sprinkle flour and paprika over the vegetables. Stir well and cook for 1 minute to remove the raw flour taste.
Step 6: Deglaze with Wine
Pour in white wine (or extra broth), scraping any browned bits from the bottom of the pan. Simmer for 2–3 minutes until slightly reduced.
Step 7: Build the Sauce
Add vegetable broth, soy sauce, and Dijon mustard. Stir well, bring to a gentle simmer, and cook for 4–5 minutes until the sauce thickens.
Step 8: Finish with Sour Cream
Reduce heat to low. Stir in sour cream until smooth and heated through (do not boil). Season to taste with salt and pepper.
Step 9: Serve
Serve stroganoff immediately over egg noodles. Garnish with chopped parsley.

Zusatztipps für die Zubereitung

For the best results, don't rush the mushroom cooking process—letting them brown properly intensifies their umami flavor and prevents a watery sauce. When adding the sour cream, make sure to reduce the heat to low and stir gently; boiling can cause it to separate. If your sauce seems too thick, thin it with a splash of vegetable broth. For a richer flavor, use a combination of mushroom varieties like shiitake, oyster, and cremini. The dish tastes even better the next day as the flavors meld together, making it ideal for meal prep.

Varianten und Anpassungen

This recipe is wonderfully adaptable to different dietary needs and preferences. For a vegan version, substitute vegan butter and plant-based sour cream, and use vegan pasta instead of egg noodles. To make it gluten-free, swap the egg noodles for gluten-free pasta and use a gluten-free flour blend for thickening; also ensure your soy sauce is gluten-free or use tamari. Add a pinch of smoked paprika for deeper, more complex flavor. You can also stir in a handful of fresh spinach or kale at the end for added nutrition. For a lighter version, use Greek yogurt in place of half the sour cream.

Serviervorschläge

This stroganoff is delicious served over traditional wide egg noodles, but also works beautifully with rice, mashed potatoes, or even crusty bread for soaking up the sauce. Pair it with a simple green salad dressed with lemon vinaigrette to cut through the richness, or serve alongside roasted vegetables like green beans or asparagus. For wine pairing, a crisp white wine such as Sauvignon Blanc complements the creamy sauce perfectly, while a light-bodied red like Pinot Noir also works well. Garnish generously with fresh parsley for a pop of color and freshness, and consider a sprinkle of extra paprika for visual appeal.
