Dairy-Free Alfredo Sauce

A rich, silky dairy-free Alfredo sauce made with soaked cashews, roasted garlic, nutritional yeast, and a touch of white miso for deep umami. It clings beautifully to fettuccine, drapes over roasted vegetables, and reheats like a dream — all without a drop of butter, cream, or parmesan.

Ingredients

Base

1 cupRaw cashews
6 clovesGarlic cloves, peeled
1 tbspOlive oil
1 cupUnsweetened oat milk
½ cupWater (plus more as needed)

Flavor

1 tbspNutritional yeast
1 tspWhite miso paste
1 tbspFresh lemon juice
½ tspDijon mustard
1 tspFine salt
½ tspFreshly ground black pepper
⅛ tspGround nutmeg

Finish

2 tbspDairy-free butter
2 tbspDairy-free parmesan (optional)

Garnish

1 tbspFresh parsley, chopped (optional)

Instructions

1
Place the cashews in a heatproof bowl and cover with very hot water. Soak for at least 30 minutes, or up to 2 hours for the smoothest result if your blender is not high-speed. Drain and rinse before using.
2
Preheat a small skillet over medium-low heat. Add the olive oil and the peeled garlic cloves. Cook gently, turning occasionally, for 6 to 8 minutes until the garlic is golden on all sides and soft enough to pierce easily with a knife. Do not let it brown aggressively — bitter garlic will carry through to the sauce.
3
Transfer the soaked cashews, confited garlic with any remaining oil, oat milk, water, nutritional yeast, white miso, lemon juice, Dijon, salt, black pepper, and nutmeg to a high-speed blender.
4
Blend on high for 1 to 2 minutes until the sauce is completely smooth and creamy. Scrape down the sides once or twice to catch any stray pieces of cashew. If the sauce is thicker than pourable, add water a tablespoon at a time until it just ribbons off the spatula.
5
Pour the blended sauce into a saucepan over medium-low heat. Add the dairy-free butter and whisk continuously as the sauce warms. It will tighten noticeably in the first 2 to 3 minutes — this is the starches in the cashews and oat milk setting up. Keep it moving and do not let it boil.
6
Once the sauce is hot, glossy, and coats the back of a spoon (about 4 to 5 minutes total), remove from heat. If using, whisk in the dairy-free parmesan until melted through.
7
Taste and adjust with more salt, lemon juice, or a pinch of pepper. If the sauce has thickened too much while finishing, loosen it with a splash of hot pasta water or oat milk — it should pour, not plop. Serve immediately over hot fettuccine, gnocchi, roasted vegetables, or chicken, and garnish with chopped parsley if desired.

Dairy Substitutions Used

Butter is replaced with a finishing pat of dairy-free butter for richness and gloss. Heavy cream is replaced with a blend of soaked cashews and unsweetened oat milk for body and silkiness. Parmesan's savory, funky edge is recreated with nutritional yeast and a small amount of white miso, with optional dairy-free parmesan added at the end for an extra cheesy finish.

Tips & Variations

Blender matters: A high-speed blender is the difference between velvety and gritty. If your blender is less powerful, soak the cashews for the full 2 hours and blend for an extra minute.

Confit the garlic: Gently cooking the garlic in oil instead of sautéing hard gives a mellow, almost sweet backbone to the sauce. Don't skip it — raw blended garlic is much sharper and will overpower the cashews.

Miso, not cheese: A single teaspoon of white miso adds the aged, savory quality parmesan normally provides. It should not taste like miso in the finished sauce — if it does, pull back next time.

Consistency control: The sauce thickens as it sits and as it hits hot pasta. Always reserve a cup of starchy pasta water and loosen the sauce in the pan with a splash or two right before serving.

Make ahead: The blended (unheated) sauce keeps in the refrigerator for up to 5 days in an airtight container. Reheat gently on the stove with a splash of oat milk or water, whisking to bring it back together.

Freezing: Freezes well for up to 2 months. Thaw overnight in the fridge and rewhisk over low heat — the texture returns beautifully.

Serving ideas: Toss with fettuccine and sautéed mushrooms, spoon over grilled chicken or shrimp, use as a white sauce for pizza, or thin with extra oat milk and use as a base for a dairy-free Alfredo bake.
