Can I use firm tofu instead of silken tofu?

Silken tofu is strongly recommended here — it's what gives the sauce its creamy, smooth consistency. Firm tofu is much denser and won't blend as smoothly, resulting in a grainier texture. If silken tofu isn't available, soft regular tofu is the closest substitute.

Is this recipe actually gluten-free?

Yes! The sauce itself is completely gluten-free. Just make sure to cook the recipe with certified gluten-free pasta — brands like Jovial, Barilla GF, or any lentil/chickpea pasta work great.

Can I make this without nutritional yeast?

You can, though nutritional yeast adds a savory, slightly cheesy depth that really elevates the sauce. If you don't have it, substitute with 1 teaspoon of white miso paste or a splash of low-sodium tamari (use tamari, not soy sauce, to keep it gluten-free).

Does this taste like tofu?

Not at all! Silken tofu has a very mild, neutral flavor on its own. Once it's blended with garlic, spinach, lemon, and nutritional yeast, you taste the sauce — not the tofu. Most people are genuinely surprised to learn what's in it.

Can I make the sauce ahead of time?

Absolutely. The sauce keeps in an airtight container in the fridge for up to 4 days and also freezes well (without pasta) for up to 2 months. It may thicken in the fridge — just blend again with a splash of water before using.

Can I use frozen spinach?

Yes! Thaw it completely and squeeze out as much water as possible before sautéing it. Too much excess water will dilute the sauce.

What pasta shape works best?

Short pasta with ridges or curves — like fusilli, penne, rigatoni, or rotini — holds onto the sauce the best. Long pasta like spaghetti or linguine works too, but won't grip the sauce quite as well.

Instructions

Bring a large pot of salted water to a boil. Cook pasta according to package directions until al dente. Reserve ½ cup pasta water before draining. Drain and set aside.
Heat olive oil in a large skillet over medium heat. Add diced onion and a pinch of salt. Cook 4 minutes until soft. Add garlic and red pepper flakes; cook 1–2 minutes until fragrant. Add spinach in batches and stir until completely wilted, about 2–3 minutes.
Transfer the spinach mixture to a blender. Add silken tofu, nutritional yeast, lemon juice, salt, black pepper, and ¼ cup of the reserved pasta water. Blend on high until completely smooth. Taste and adjust seasoning.
Pour the sauce back into the skillet over medium-low heat. Add the cooked pasta and toss to coat. Simmer 2–3 minutes. Add more pasta water as needed to loosen the sauce.
Divide into bowls and garnish with fresh basil, nutritional yeast, black pepper, and a drizzle of olive oil.

Notes

Storage: Refrigerate in an airtight container for up to 4 days. The sauce may thicken — add a splash of water when reheating.
Freezing: Freeze the sauce (without pasta) for up to 2 months. Thaw overnight in the fridge and re-blend before using.
Tofu tip: Silken tofu is essential for a smooth, creamy sauce. Do not substitute firm or extra-firm.
Gluten-free: Use certified GF pasta to keep this recipe fully gluten-free.
Frozen spinach: Thaw completely and squeeze out all excess water before using.
