Cheddar Not Cheese: A Creamy Dairy-Free Sauce

“Cheddar not cheese” is a smooth, dairy-free cheddar-style sauce made with cashews, nutritional yeast, and pantry seasonings. It is blended and gently heated until pourable, making it useful for pasta, vegetables, potatoes, or nachos without relying on dairy cheese.

Ingredients

1 cup (140 g) raw, unsalted cashews
1 cup (240 ml) water, plus more for soaking if needed
3 tablespoons (15 g) nutritional yeast
2 tablespoons (30 ml) lemon juice
1 tablespoon (15 ml) olive oil
1 teaspoon (5 ml) Dijon mustard
½ teaspoon garlic powder (about 1.5 g)
½ teaspoon onion powder (about 1.5 g)
½ teaspoon fine salt (about 3 g), plus more to taste
¼ teaspoon smoked paprika (about 0.5 g)
⅛ teaspoon ground turmeric (about 0.3 g), optional, for color
1 tablespoon (8 g) cornstarch
2 tablespoons (30 ml) cold water, for mixing with the cornstarch

Instructions

Soak the cashews if needed. If you have a high-speed blender, you can blend the cashews directly. Otherwise, cover them with boiling water and soak for 20 minutes, then drain and rinse. This short soak softens them enough for a smoother sauce; do not use the soaking water in the recipe.
Blend the base. Put the cashews, 1 cup (240 ml) fresh water, nutritional yeast, lemon juice, olive oil, Dijon, garlic powder, onion powder, salt, paprika, and optional turmeric in a blender. Blend for 1–2 minutes, stopping to scrape the sides, until the mixture looks completely smooth. If you still see grainy flecks, blend longer before heating.
Thicken the sauce. Pour the blended mixture into a small saucepan. In a cup, stir the cornstarch with 2 tablespoons (30 ml) cold water until no lumps remain, then whisk it into the pan. Set over medium-low heat and stir constantly for about 5 minutes, scraping the bottom and corners. The sauce should become glossy and thick enough to coat a spoon. Keep it below a hard boil, which can cause splattering and uneven thickening.
Adjust and serve. Taste carefully and add salt or lemon juice a little at a time if it needs more seasoning or brightness. For a thinner sauce, whisk in warm water 1 tablespoon (15 ml) at a time. Serve warm; it thickens further as it cools.

Tips

Choose the right cashews. Use raw, unsalted cashews rather than roasted or salted ones. Roasted nuts give the sauce a stronger flavor and may make its color darker; if using salted cashews, reduce the added salt and adjust only after blending.
Blend before thickening. Cornstarch can make a sauce feel lumpy if added directly to a hot mixture. Always dissolve it in cold water first, and make the base as smooth as possible before it goes in the pan.
Use a practical substitute. For a cashew-free version, use 1 cup (150 g) cooked, peeled potato and ½ cup (75 g) cooked carrot in place of the cashews, and start with ¾ cup (180 ml) water. Blend until smooth; expect a less rich, more vegetable-forward sauce. Check labels if avoiding allergens, as nutritional yeast and prepared mustard can have cross-contact or added ingredients.
Season in stages. Lemon juice, mustard, and nutritional yeast vary by brand. Begin with the measured amounts, then adjust after heating. More lemon makes the sauce tangier, while extra water loosens it without changing the seasoning as much.

Serving Suggestions

Spoon the warm sauce over steamed broccoli, roasted cauliflower, baked potatoes, or a tray of roasted vegetables. For a quick pasta meal, toss it with about 12 ounces (340 g) cooked pasta and loosen with a splash of pasta water until it coats the noodles. It also works as a dip for tortilla chips, pretzels, or raw vegetables; keep it warm in a small slow cooker on a low setting for serving, and stir occasionally so a skin does not form.

For nachos, drizzle the sauce over chips just before serving and add beans, salsa, sliced scallions, or pickled jalapeños. The sauce is not designed to brown or stretch like melted cheddar, so use it as a creamy topping rather than expecting a baked cheese layer.

Variations

For a smoky version, increase the smoked paprika to ½ teaspoon, or add a small pinch of chipotle powder for heat. For a jalapeño-style dip, blend in one seeded, finely chopped pickled jalapeño and a teaspoon of its brine, then taste before adding more salt. To make a milder sauce for children or sensitive palates, omit the smoked paprika and use only 1 tablespoon (15 ml) lemon juice.

You can also change the consistency for different uses. Keep it thick for dipping or spreading, or add warm water in small amounts for a drizzle. For a richer finish, whisk in 1 teaspoon (5 ml) olive oil after heating. These adjustments change the texture and flavor but do not make the sauce behave exactly like dairy cheddar.

Storage and Reheating

Transfer leftovers to a clean, covered container and refrigerate within 2 hours of cooking. The sauce keeps for 3–4 days in the refrigerator. It firms up when cold, so stir in a tablespoon or two of water before reheating. Warm it in a saucepan over low heat, stirring frequently, or microwave in short 20–30 second bursts, stirring between each, until evenly hot. Reheat only the portion you plan to use, and do not leave it sitting at room temperature for more than 2 hours.

Freezing is possible, but the texture may become slightly grainy after thawing. Freeze in a sealed container for up to 2 months for best quality, thaw overnight in the refrigerator, then blend or whisk while gently reheating. Add water gradually to restore a pourable texture.

Frequently Asked Questions

Does this taste exactly like cheddar? No. Nutritional yeast, mustard, lemon, and paprika create a savory, tangy, cheddar-inspired flavor, but the sauce tastes distinctly of cashews and does not melt, stretch, or brown like dairy cheese.

Do I have to soak the cashews? Not if your blender makes a smooth puree from raw nuts. Soaking is helpful for standard blenders and makes the cashews easier to blend. If the sauce feels gritty, blend longer or pass it through a fine-mesh sieve.

Can I make it without a blender? A blender is the best tool for a smooth result. A food processor may leave the sauce somewhat textured; if using one, process the cashews thoroughly with part of the water before adding the remaining ingredients. Chopped cashews alone will not give the same creamy consistency.

Why did my sauce turn too thick? Cornstarch thickens as the sauce heats and continues to set as it cools. Whisk in warm water a tablespoon (15 ml) at a time until it reaches the consistency you want. Next time, reduce the cornstarch slightly if you prefer a thinner sauce.

Can I make it ahead? Yes. Prepare it up to 3 days ahead, refrigerate promptly, and reheat gently with a little water. The flavor is best after a quick stir and taste adjustment just before serving.

Is nutritional yeast the same as baking yeast? No. Nutritional yeast is an inactive savory seasoning, often sold as flakes or powder. Active dry yeast or instant yeast is for baking and is not a suitable substitute in this sauce.
