Yes — use cashew milk instead of milk 1:1, cup for cup, and it is one of the quietest swaps you can make. Cashew milk is mild, creamy, and almost neutral in flavour, so it disappears into white sauces, soups, and cakes in a way that coconut milk never will. If a recipe asks for 1 cup of milk, pour in 1 cup of unsweetened cashew milk and change nothing else. It is the plant milk to reach for when you want the swap to be invisible, and it is especially good in creamy savoury cooking, where oat milk can taste a little sweet and soy milk can taste a little beany.
How much cashew milk to use
| Milk in the recipe | Cashew milk to use |
|---|---|
| 1/4 cup | 1/4 cup |
| 1/3 cup | 1/3 cup |
| 1/2 cup | 1/2 cup |
| 3/4 cup | 3/4 cup |
| 1 cup | 1 cup |
| 1 1/2 cups | 1 1/2 cups |
| 2 cups | 2 cups |
The ratio is 1:1 at every amount. Cashew milk is thinner than dairy milk, so in a recipe that needs body — a thick béchamel, for instance — you may want to cook the sauce a minute longer or add a touch more flour to the roux.
Worked example 1: a white sauce for cauliflower cheese
Your cauliflower cheese asks for 2 cups of milk in the sauce. Use 2 cups of unsweetened cashew milk, warmed gently before you add it to the roux. The sauce will be smooth, pale, and neutral, and the cheese will be the flavour you taste, which is exactly what you want. Because cashew milk is thin, let the sauce simmer for an extra minute to reach coating consistency, and add the cheese off the heat so the sauce does not split. Sweetened cashew milk would ruin this dish, so check the carton — vanilla-flavoured cashew milk is common and it does not belong in a cheese sauce.
Worked example 2: a vanilla panna cotta, dairy-free
A panna cotta is a hard test for any milk substitute, because milk is the star. Use 2 cups of unsweetened cashew milk with gelatine, sugar, and vanilla, exactly as the dairy recipe says. The result will be lighter and less rich than a dairy panna cotta, because cashew milk has less fat and no casein, but it will set cleanly and taste delicately of vanilla. Serve it with a sharp berry coulis, which gives the dessert the richness it lost. This works better than oat milk here, because oat milk's starch can make a set dessert slightly cloudy.
Worked example 3: creamy tomato soup
A tomato soup finishes with 1/2 cup of milk stirred in for creaminess. Use 1/2 cup of cashew milk, and add it off the heat, stirring gently. Cashew milk is less likely to split in acid than soy milk, which makes it a safer choice for tomato soup, and its neutral flavour will not fight the tomato. If you want the soup richer, blend in a small handful of soaked cashews as well — that is a different technique, but it pairs naturally with the same carton. The soup will be silky, pale, and dairy-free without tasting like a compromise.
What changes when you use cashew milk
Flavour barely changes, which is the point. Cashew milk is the most neutral plant milk, with only a faint nuttiness that vanishes in cooking. Texture changes a little: it is thinner than whole milk, so sauces and custards are lighter and may need a minute longer to thicken. Browning changes too — cashew milk has very little protein, so baked goods come out paler, and a wash of cashew milk on pastry will not brown the way dairy milk does. Fat is lower than whole milk, so desserts made with it feel lighter. None of these is a defect; they are the trade for a swap that nobody at the table will detect.
Method and source
The 1:1 ratio comes from the CookScale substitution data, which records that plant milks swap 1:1 in most recipes and warns that sweetened or flavoured versions change the taste. The same data warns not to use sweetened or flavoured plant milk in savoury sauces and not to expect the same browning in baking — both apply to cashew milk, and the browning warning matters more here than with soy milk because cashew milk is so low in protein. This is a volume-for-volume liquid swap, so no density figure applies. Treat the result as approximate: brands vary in thickness, and some cartons are mostly water, so buy a brand you trust and taste as you go.
Practical guidance
Buy unsweetened cashew milk for cooking, and check the label — many cartons are sweetened or vanilla-flavoured, and those belong in cereal, not in a sauce. Because cashew milk is thin, keep a little cornflour nearby when you make sauces: a teaspoon whisked into the cold cashew milk before heating gives you the body that dairy would have provided. Store opened cartons in the fridge for five to seven days. The one hard rule is allergy: cashew milk is a tree-nut product, so never serve it to someone with a nut allergy, and do not use it in a dish for a mixed group unless you have checked. For everyone else, it is the most discreet milk substitute in the cupboard.
Frequently asked questions
Can I use cashew milk instead of milk in baking?
Yes. Use it 1:1 in cakes, muffins, and pancakes, choosing unsweetened. Expect a slightly paler crust and a lighter crumb, and add a drop more vanilla if the cake is plain, since cashew milk adds almost no flavour of its own.
Is cashew milk good in savoury sauces?
Yes — it is one of the best plant milks for savoury cooking, because it is neutral and creamy. Use it in white sauces, soups, and mashed potatoes. Avoid sweetened or vanilla cartons, and cook sauces a minute longer, since cashew milk is thinner than dairy milk.
Does cashew milk curdle in coffee or tea?
It is fairly stable, more so than soy milk, but it can still split in very acidic coffee. Warm it first, or use a barista blend. In cooked dishes, add it off the heat in acidic recipes such as tomato soup.
Can I use cashew milk for custard?
It works in a baked custard or a bread pudding, where egg does the setting. A stirred custard will be thinner and lighter than a dairy one. For a set dessert such as panna cotta, it sets cleanly with gelatine and tastes delicate, especially with a fruit sauce.
Is cashew milk safe for people with nut allergies?
No. Cashew milk is made from cashews, which are tree nuts, and it is not safe for anyone with a tree-nut allergy. Use oat milk or soy milk instead for allergy-friendly cooking, and always check with the person eating the food.
Does cashew milk taste of nuts?
Barely. Unsweetened cashew milk has a very faint nutty note in a glass, and it disappears in cooking. It is the most neutral-tasting plant milk, which is why it is a good choice when you do not want the substitute to be noticed.
