Instant Vegan Cheese Sauce Powder

For mac’n’cheese, cauliflower/broccoli cheese, layers in lasagnes or moussakas, cheesy mushroom and leek pies and more… This instant powder is so useful to store in your pantry to whip up a quick mid-week meal. Just add oat milk and a little olive oil or melted vegan butter.

  1. Measure all the ingredients into a jar and give it a good shake to evenly mix into a powder. If you don’t have mustard powder then leave it out and add dijon mustard or whatever mustard you like in the wet stage described in the next step.
  2. In a measuring jug, pour 100ml of oat milk per person. Then whisk in 1 tbsp of the powder and 1 tbsp of good olive oil (or melted vegan butter) per person. If you mix doesn’t have mustard powder, add a tsp of Dijon mustard per person too.
  3. Pour the mixture into a pot over a medium/low heat and whisk continuously until it is cooked through. It should be creamy, silky smooth and nice and thick. Taste and adjust the seasoning if you need to, then use the sauce however you like. Fold through cooked pasta, layer up in a lasagne or moussaka, pour over cooked mushrooms, leeks and butterbeans then top with pastry and bake… I always use this sauce for a cauliflower and broccoli cheese as part of our Sunday roast.
