I’ll be honest, I doubted a handful of soaked cashews could stand in for sour cream. Then I made this three times in one week and stopped questioning it.
Creamy Cashew Mushroom Stroganoff is a dairy-free spin on the classic, built from blended cashews, browned mushrooms, and a splash of tamari for depth. No sour cream, no butter, no flour roux. Just a blender and one skillet.
The sauce is rich and a little tangy from mustard and lemon. The mushrooms bring the earthy backbone. Tossed with wide noodles, it eats like the stroganoff I grew up with, minus the dairy.
It’s a weeknight dish. Blend the cashew cream while the pasta boils and the whole thing comes together in under 40 minutes.
Why You’ll Love This Recipe
- Cashew cream replaces dairy without losing the tangy body
- One skillet for the sauce, one pot for noodles
- Ready in 40 minutes for a weeknight dinner
- Freezes well as a sauce for easy meal prep
Ingredient Notes
- Raw cashews: Soak in hot water for 15 minutes so they blend smooth. Skip this step only if you have a high-speed blender.
- Cremini and shiitake mushrooms: Mixing the two gives more earthy depth. Straight cremini or button mushrooms work fine on their own.
- Tamari: Adds the savory backbone that meat usually brings. Regular soy sauce works too, but check the label if you need this gluten-free.
- Dijon mustard: Gives the sauce its tang, standing in for the sour cream bite in classic stroganoff.
- Wide egg-free noodles: Pappardelle or tagliatelle hold the sauce well. Use a gluten-free pasta shape if needed, same cook time on the package usually applies.
Cashew Mushroom Stroganoff: Creamy and Dairy-Free
Ingredients
Method
- Soak the cashews in hot water for 15 minutes, then drain. Meanwhile, bring a large pot of salted water to a boil.
- Cook the noodles according to the package, 9 to 11 minutes, until al dente. Reserve 120 ml (1/2 cup) pasta water, then drain.
- Blend the drained cashews with 240 ml (1 cup) vegetable broth, the mustard, and lemon juice until completely smooth, about 1 to 2 minutes. Set the cashew cream aside.
- Heat the olive oil in a 12-inch / 30 cm skillet over medium heat. Add the onion and cook for 5 to 6 minutes, stirring occasionally, until soft and lightly golden.
- Add the garlic and cook for 30 seconds until fragrant.
- Add both mushrooms in a single layer and let them sit undisturbed for 2 to 3 minutes before stirring. Cook for 8 to 10 minutes total until browned and any released liquid has evaporated. Don’t crowd the pan or the mushrooms will steam instead of brown.
- Stir in the smoked paprika, thyme, tamari, and the remaining 240 ml (1 cup) broth. Simmer for 3 to 4 minutes.
- Reduce the heat to low and stir in the cashew cream. Simmer gently for 4 to 5 minutes, stirring often, until the sauce thickens and coats the back of a spoon.
- Add the cooked noodles to the skillet and toss to coat, thinning with reserved pasta water a splash at a time if the sauce is too thick.
- Season with salt and pepper, scatter with parsley, and serve right away.
Notes
- Soak cashews in hot water while you prep everything else to save time
- Don’t crowd the mushrooms, cook in a wide skillet so they brown, not steam
- Keep heat low once cashew cream goes in to avoid separating
- Reserve pasta water before draining, it’s the easiest fix for a thick sauce
Tips for Success
- Blend the cashew cream for a full 1 to 2 minutes so it comes out silky, not grainy.
- Let the mushrooms sit undisturbed for a couple minutes per side so they brown instead of steam.
- Reserve a half cup of pasta water before draining, it loosens the sauce if it tightens up.
- Add the cashew cream on low heat only, high heat can make it separate and turn grainy.
- Taste before salting, tamari and broth both bring sodium so go light at first.
Variations
- Stir in a handful of baby spinach at the end for color and a mild vegetable boost.
- Swap half the mushrooms for sliced portobello caps for a meatier bite and texture.
- Use a splash of white wine in place of some broth when deglazing the mushrooms for extra depth.
Storage and Reheating
Store leftover stroganoff in an airtight container in the fridge for 3 to 4 days. The noodles soften a bit as they sit, but the sauce holds up well.
Reheat gently in a skillet over low heat with a splash of broth or water to loosen the sauce, stirring often for 4 to 5 minutes until warmed through. Microwave works too, in 30-second bursts, stirring between each.
For longer storage, freeze the sauce on its own before tossing with noodles, up to 2 months in a sealed container. Thaw overnight in the fridge and reheat on the stove before combining with freshly cooked pasta.
Serving Suggestions
Serve creamy cashew mushroom stroganoff straight from the skillet with a good grind of black pepper and a scatter of fresh parsley.
A simple green salad with lemon vinaigrette cuts through the richness. Steamed green beans or roasted broccoli work the same way if you want something warm on the side.
Crusty bread is worth having on the table too, it’s good for chasing down the last of the sauce once the noodles are gone.
FAQ
Why is my cashew mushroom stroganoff sauce too thin?
Thin sauce usually means the cashew cream didn’t simmer long enough or the cashews weren’t blended long enough to break down fully. Simmer the finished sauce 2 to 3 minutes longer on low heat, stirring, and blend the cream a full 1 to 2 minutes next time for a silkier base.
Can I use sour cream instead of cashew cream in this stroganoff?
Yes, swap in 1 cup of sour cream in place of the cashew cream, added at the same low-heat step so it doesn’t curdle. It turns the dish into a dairy version with a slightly tangier, thinner sauce than the cashew blend gives you.
Can I freeze creamy cashew mushroom stroganoff?
Freeze the sauce on its own before tossing it with noodles, not the fully assembled dish. Cashew cream can separate once thawed and pasta turns mushy in the freezer. Store the sauce up to 2 months, thaw overnight, then reheat gently on the stove before combining with fresh noodles.
What goes well with creamy cashew mushroom stroganoff?
A simple green salad with lemon vinaigrette or steamed green beans both cut through the richness of the sauce. Crusty bread on the side is worth it for mopping up leftover sauce once the noodles are gone.
Is cashew mushroom stroganoff gluten free?
The sauce itself, cashews, mushrooms, and broth, is naturally gluten free. To make the full dish gluten free, swap the wheat noodles for a gluten-free pasta shape and double check your tamari label, since some brands add wheat.
How is this different from classic beef stroganoff?
This version swaps beef and sour cream for mushrooms and blended cashews, but keeps the tangy mustard note and thick body of the original sauce. The result is vegan and a bit lighter, and it still coats the noodles the same way classic stroganoff does.
