Ingredient breakdown: key components
- Cashews: I love how their creamy texture becomes the base of this sauce, giving it that luscious mouthfeel. Soak them at least 4 hours, or quick-soak for 30 mins, then blend until silky smooth. Skip if you’re allergic—add more silken tofu for creaminess.
- Nutritional Yeast: This cheesy umami boost makes the sauce sing without dairy. I recommend tasting as you go; a little goes a long way. If you want a deeper flavor, toast it lightly in a dry pan first for a nutty aroma.
- Garlic: The aroma of roasting garlic is what sets this sauce apart—sweet and smoky. Roast whole cloves in a hot pan until golden and fragrant, about 2-3 mins. If it’s bitter, you’ve overdone it; reduce heat and add a splash of water to stop the browning.
- Plant-Based Milk: I prefer unsweetened cashew or oat milk for their neutral, rich qualities. Warm it gently on low heat before blending—cold milk can cause clumps. If it’s too thin, simmer gently until slightly thickened before adding to the sauce.
- Olive Oil: A good splash adds depth and richness while sautéing garlic. Use a light hand if you want a less greasy sauce. If it’s too greasy, whisk in a teaspoon of lemon juice to brighten and cut the oil.
- Lemon Juice: Brightens the sauce instantly. Freshly squeezed is best—roll the lemon on the counter first to maximize juice yield. If it’s too sharp, balance with a pinch of sugar or a splash more plant milk.
- Salt & Pepper: Season gradually, tasting as you go. A pinch of smoked paprika can add a subtle smoky layer if you like. If it’s bland, it needs a little more salt or a squeeze of lemon to awaken the flavors.

Notes for ingredient swaps
- Dairy-Free: Swap cow’s milk with coconut or almond milk for a richer, slightly sweeter sauce. The texture stays creamy, but it gains a subtle nutty or coconut note.
- Nut Alternatives: Use silken tofu or cooked cauliflower instead of cashews if allergies are a concern. They’ll add creaminess but lack the nutty richness.
- Flavor Boost: Nutritional yeast can be replaced with vegan Parmesan or a dash of miso paste for a sharper, more umami punch.
- Garlic Variations: Roasted garlic adds a smoky sweetness, but raw garlic or garlic powder works in a pinch—just don’t overdo it to avoid bitterness.
- Lemon Juice: Lemon zest or apple cider vinegar can brighten the sauce if fresh lemon isn’t available. Adjust to taste—start small.
- Olive Oil: Use avocado oil or vegan butter for a different but equally rich finish. Keep in mind, the flavor profile will shift slightly.
- Pasta Options: Use zucchini noodles or spaghetti squash for a lower-carb version. They’ll hold the sauce well but cook faster and softer.
