Ingredients
The heart of this pasta is a blend of fresh, wholesome components. Whole‑grain spaghetti provides a nutty base, while a medley of cremini, shiitake, and button mushrooms adds texture and depth. Soaked cashews create a velvety sauce without dairy, and nutritional yeast supplies a cheesy note. Aromatics like garlic and shallots lift the flavor, and a splash of white wine adds brightness. Finishing herbs bring a pop of freshness that ties everything together.
Pasta & Main Ingredients
- 12 oz whole‑grain spaghetti
- 2 tbsp olive oil
- 1 lb mixed mushrooms (cremini, shiitake, button), sliced
Cashew Cream Sauce
- 1 cup raw cashews, soaked 4 hrs
- ¾ cup vegetable broth (low‑sodium)
- 2 tbsp nutritional yeast
- 1 tbsp lemon juice
Aromatics & Seasonings
- 2 shallots, finely diced
- 3 garlic cloves, minced
- ½ cup dry white wine (optional)
- ¼ tsp red‑pepper flakes (optional)
- Salt and freshly cracked black pepper, to taste
- 2 tbsp fresh parsley, chopped (for garnish)
Each component plays a specific role: the cashews give body, the broth adds savory depth, and the nutritional yeast introduces a subtle cheese note. The wine deglazes the pan, releasing caramelized bits that intensify the mushroom flavor. Together, they create a sauce that clings lovingly to every strand of pasta, ensuring every bite is rich, comforting, and completely plant‑based.
Step-by-Step Instructions
Preparing the Cashew Cream
While the pasta boils, drain the soaked cashews and place them in a high‑speed blender. Add the vegetable broth, nutritional yeast, lemon juice, and a pinch of salt. Blend on high for 1‑2 minutes until the mixture is completely smooth and resembles a thick cream. Set aside; this will become the sauce base.
Cooking the Pasta
Bring a large pot of salted water to a rolling boil. Add the whole‑grain spaghetti and cook according to package directions, usually 9‑11 minutes, until al dente. Reserve ½ cup of the pasta cooking water, then drain the noodles and set aside.
Sautéing the Mushrooms
- Heat the Pan. Over medium heat, add the olive oil to a large skillet. Once shimmering, toss in the sliced mushrooms in a single layer. Let them sit untouched for 2‑3 minutes to develop a golden crust before stirring.
- Deglaze. If using wine, pour it over the browned mushrooms, scraping the fond with a wooden spoon. Allow the liquid to reduce by half, about 2 minutes, which concentrates flavor without adding excess moisture.
- Add Aromatics. Stir in the diced shallots, minced garlic, and red‑pepper flakes. Cook for another 30‑45 seconds until fragrant, being careful not to let the garlic brown.
Combining Sauce & Pasta
- Incorporate Cashew Cream. Reduce the heat to low and pour the blended cashew cream into the mushroom mixture. Stir continuously; the sauce will thicken within 2‑3 minutes. If it becomes too thick, add a splash of the reserved pasta water until you reach a silky consistency.
- Season. Taste and adjust with salt, pepper, and an extra squeeze of lemon juice if desired. The acidity balances the richness of the cashews and brightens the overall palate.
- Finish with Pasta. Add the cooked spaghetti directly into the skillet. Toss gently to coat every strand, allowing the sauce to cling. Cook together for 1‑2 minutes so the pasta absorbs some of the sauce, creating a cohesive dish.
Plating & Garnish
Divide the pasta among warm bowls. Sprinkle chopped fresh parsley over the top for color and a herbaceous lift. Serve immediately while the sauce is glossy and the mushrooms are still tender.
Tips & Tricks
Perfecting the Recipe
Soak Cashews Properly. A minimum of 4 hours (or overnight) ensures a silky texture; quick‑soak in hot water for 30 minutes if short on time.
Reserve Pasta Water. Starchy water helps bind the sauce to the pasta and prevents a dry finish.
Don’t Overcrowd the Pan. Cook mushrooms in batches if necessary; this yields better caramelization and richer flavor.
Finish on Low Heat. Adding the cashew cream over low flame prevents curdling and keeps the sauce smooth.
Flavor Enhancements
A drizzle of truffle oil adds an earthy luxury, while a handful of toasted pine nuts contributes crunch. For a smoky twist, stir in a teaspoon of smoked paprika with the aromatics. Finish with a splash of soy‑free tamari for an umami boost.
Common Mistakes to Avoid
Avoid blending the cashew sauce while it’s still hot; this can create a grainy texture. Also, don’t skip the deglazing step—those browned bits are flavor gold. Finally, resist the urge to over‑mix after adding pasta; gentle tossing preserves the sauce’s silkiness.
Pro Tips
Use a High‑Speed Blender. It creates the smoothest cashew cream with no lumps.
Season in Layers. Add a pinch of salt at each stage—mushrooms, sauce, and final plating—for balanced seasoning.
Warm the Serving Bowls. A hot bowl keeps the pasta from cooling too quickly, preserving the sauce’s velvety texture.
Finish with Fresh Herbs. Adding parsley or basil at the end brightens the dish and adds a pop of color.
Variations
Ingredient Swaps
Replace whole‑grain spaghetti with gluten‑free rice noodles or spiralized zucchini for a low‑carb twist. Swap cremini mushrooms for oyster or portobello mushrooms for a heartier bite. If cashews are a concern, use soaked almonds or silken tofu as the cream base, adjusting liquid for consistency.
Dietary Adjustments
For a raw‑vegan version, blend soaked cashews with raw mushroom broth and serve over raw zucchini ribbons. To make it keto‑friendly, omit the pasta and serve the sauce over cauliflower rice or shirataki noodles. All ingredients are naturally vegan, gluten‑free (when using GF pasta), and soy‑free.
Serving Suggestions
Pair the pasta with a crisp arugula salad dressed in lemon‑olive oil, or serve alongside roasted Brussels sprouts for extra crunch. A side of warm, crusty gluten‑free bread is perfect for mopping up any remaining sauce. For a festive touch, sprinkle toasted hazelnuts and a drizzle of balsamic reduction.
Storage Info
Leftover Storage
Allow the pasta to cool to room temperature, then transfer it to an airtight container. Store in the refrigerator for up to 4 days. For longer keep, portion the dish into freezer‑safe bags, removing as much air as possible, and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating Instructions
Reheat gently on the stovetop over low heat, adding a splash of vegetable broth or water to restore creaminess. Stir frequently until warmed through, about 5‑7 minutes. In the oven, cover the dish with foil and bake at 350°F for 12‑15 minutes. Microwaving works for single servings—heat 30‑second intervals, stirring in between, and finish with a drizzle of fresh cashew cream.
