Mushroom Stroganoff Recipe: Creamy Vegetarian Comfort in 30 Minutes

A mushroom stroganoff is the vegetarian dinner that never feels like a compromise: mixed mushrooms browned until deeply savoury, folded into a silky sour-cream sauce, and spooned over buttery egg noodles. It is on the table in 30 minutes, it uses one pan plus a pot for the noodles, and it tastes like something that simmered all afternoon.

The secret is browning, not boiling. Mushrooms need space, high heat and patience before any liquid goes in — that golden colour is where the flavour lives. Once the sauce comes together, keep it gentle: sour cream added off a fierce boil stays smooth and glossy instead of splitting.

Rich, creamy and deeply savoury — the meat-free stroganoff that still tastes like comfort food.

Mushrooms, stock and sour cream — a short list that builds a surprisingly deep sauce.

Ingredients

• 600 g / 1 lb 5 oz mixed mushrooms (chestnut, button and portobello), thickly sliced
• 1 large onion, finely diced
• 3 garlic cloves, minced
• 2 tbsp butter
• 1 tbsp olive oil
• 1 tbsp plain flour
• 240 ml / 1 cup vegetable stock
• 1 tbsp tomato paste
• 1 tsp Dijon mustard
• 1 tsp smoked paprika
• 150 g / 2/3 cup sour cream, at room temperature
• 300 g / 10 1/2 oz dried egg noodles
• 1 tsp salt, plus more to taste
• 1/2 tsp black pepper
• 2 tbsp chopped fresh parsley, to serve

Glossy sauce, tender mushrooms, silky noodles — keep the heat gentle so the sour cream never splits.

Instructions

1. Cook the noodles: Bring a large pot of salted water to a boil and cook the egg noodles according to the packet, usually 6–8 minutes, until just tender. Drain, toss with a knob of butter, and keep warm.
2. Brown the mushrooms: Heat the olive oil and half the butter in a large deep pan over medium-high heat. Add the mushrooms in a single layer, in batches if needed, and cook without stirring for 3–4 minutes per side until deeply golden. Remove to a plate and season with salt.
3. Soften the onion: Lower the heat to medium, melt the remaining butter, and cook the onion for 4–5 minutes until soft and translucent. Add the garlic and smoked paprika and stir for 30 seconds until fragrant.
4. Build the sauce base: Sprinkle over the flour and stir for 1 minute to cook out the raw taste. Stir in the tomato paste and Dijon mustard, then pour in the vegetable stock a little at a time, stirring constantly, until smooth.
5. Simmer: Return the mushrooms to the pan, season with salt and pepper, and simmer gently for 5 minutes until the sauce thickens enough to coat a spoon.
6. Finish with sour cream: Take the pan off the heat and stir in the sour cream until the sauce turns glossy and pale gold. Taste and adjust the salt, mustard and pepper — the sauce should be savoury, tangy and well seasoned.
7. Serve: Spoon the stroganoff over the warm egg noodles, scatter with parsley, and serve immediately while the sauce is silky and hot.

Tips & Variations

• Do not crowd the pan. Mushrooms release water and steam instead of browning if they are packed in. Cook in two batches if your pan is small — the extra few minutes are worth it.
• Use mixed mushrooms. Chestnut mushrooms give body, portobello adds meatiness, and a handful of shiitake brings a deeper, almost smoky note. One variety alone still works, but the mix is better.
• Keep sour cream at room temperature. Cold sour cream straight from the fridge is far more likely to split. Take it out when you start cooking, and always stir it in off the heat.
• Add a splash of brandy or white wine. Deglaze the pan with 60 ml / 1/4 cup after the onions soften, let it bubble away, then continue — it adds a classic stroganoff depth.
• Make it dairy-free. Swap the butter for olive oil and the sour cream for a plant-based sour cream or cashew cream. The sauce stays creamy, though slightly less tangy.
• Serve it over rice or mash. Egg noodles are traditional, but this sauce is just as good over fluffy rice, mashed potatoes or buttered tagliatelle.
• Leftovers reheat gently. Warm leftovers over low heat with a splash of stock or water, and never let the sauce boil — a rolling boil is what makes sour-cream sauces grainy.

Nutrition Note

Per serving, this stroganoff provides roughly 480 kcal, 15 g protein, 58 g carbohydrates and 22 g fat. Mushrooms supply B vitamins, selenium and a satisfying savouriness for very few calories, while the egg noodles provide the bulk of the energy. Sour cream is the main source of saturated fat, so a lighter version can use half sour cream and half plain yoghurt stirred in off the heat, with no loss of tang.

FAQ

Can I use only one type of mushroom?

Yes — chestnut or button mushrooms alone make a very good stroganoff. Mixed mushrooms simply give a more complex flavour and varied texture.

Why did my sauce split?

Almost always because the sour cream went into a boiling sauce, or it was fridge-cold. Stir it in off the heat, with the cream at room temperature, and the sauce stays smooth.

Can I make mushroom stroganoff ahead?

Yes, up to 2 days in the fridge. Reheat gently over low heat with a splash of stock, and cook fresh noodles on the day — reheated noodles go soft.

Is mushroom stroganoff gluten-free?

The sauce can be: swap the flour for cornstarch mixed with a little cold water, and serve over rice or gluten-free pasta instead of egg noodles.

Can I freeze mushroom stroganoff?

It freezes, but the sour-cream sauce can turn slightly grainy on thawing. For best results, freeze the sauce before adding the sour cream, then stir it in fresh when reheating.
