Instructions

Step 1: Prepare the zucchini noodles
Spiralize the zucchini and gently pat dry with paper towels to remove excess moisture.
Step 2: Sauté the noodles
In a large skillet, heat olive oil over medium heat. Add zucchini noodles and sauté for 2–3 minutes, just until slightly tender. Season with sea salt. Remove from heat and set aside.
Step 3: Make the cashew Alfredo sauce
In a high-speed blender, combine soaked and drained cashews, plant-based milk, nutritional yeast, lemon juice, garlic, onion powder, sea salt, and black pepper. Blend until completely smooth and creamy, scraping down sides as needed.
Step 4: Warm the sauce
Pour the sauce into a saucepan and warm over low heat for 3–4 minutes, stirring frequently, until heated through. Add a splash more plant milk if the sauce is too thick.
Step 5: Toss and coat
Toss the warm zucchini noodles with the creamy Alfredo sauce until evenly coated.
Step 6: Serve
Serve immediately, garnished with fresh parsley, toasted pine nuts, and extra black pepper if desired.

Zusatztipps für die Zubereitung

For the smoothest sauce, ensure the cashews are soaked in hot water for at least 20 minutes. If the sauce thickens too much while warming in the saucepan, whisk in a small amount of plant milk until you reach your desired consistency.

Recipe FAQs

How do I prevent zucchini noodles from becoming watery?

Gently pat spiralized zucchini dry with paper towels before cooking. Sauté just 2-3 minutes until slightly tender rather than soft, which helps maintain texture and prevents excess moisture from thinning the sauce.

Can I make the cashew Alfredo sauce ahead of time?

Absolutely. Blend the sauce and store refrigerated for up to 4 days. When ready to serve, warm gently over low heat, adding a splash of plant milk if needed to regain creamy consistency.

What's the best way to soak cashews quickly?

Boil water, pour over raw cashews, and let soak for 20 minutes. For even faster results, simmer cashews in water for 10-15 minutes until tender. Drain thoroughly before blending.

Are there substitutions for nutritional yeast?

Nutritional yeast provides essential cheesy flavor. While white miso paste adds depth, it won't replicate the same savory notes. For closest results, combine a pinch of miso with a small amount of vegan parmesan.

Can I use regular pasta instead of zucchini noodles?

Yes, this sauce pairs beautifully with gluten-free pasta, whole wheat pasta, or traditional Italian pasta. Cook pasta al dente, reserve some pasta water, and toss with sauce for perfect coating.

How do I achieve the smoothest sauce texture?

Use a high-speed blender and blend for 1-2 full minutes. Stop to scrape down sides and continue blending until absolutely silky. If small bits remain, strain through a fine-mesh sieve for restaurant-smooth results.
