Ingredients and Substitutions
There’s a printable recipe card for this gluten free cheese sauce recipe below. But for the shopping list here are the main ingredients you’ll need.
- Butter: If you want to make this recipe dairy free, use a vegan margarine instead.
- Plain Gluten Free Flour: I use a plain gluten free flour blend like FREEE. Any supermarket blend should work – or a 1:1 gluten free flour in the US.
- Milk: I use either full-fat or semi-skimmed milk. Dairy free milk such as soya milk or gluten free oat milk will also work for a gluten free vegan white sauce.
- Cheese: I always use a sharp Cheddar cheese for maximum flavour. If you like, you could try use Stilton, Mexicana Cheese or even Gruyere for different flavours.
- Dijon Mustard: This is optional but I love the extra flavour it adds. Most dijon mustard is gluten free but always double check.
- Nutmeg: Don’t underestimate the power of a tiny bit of nutmeg to elevate your sauce!
How to Make Gluten Free Cheese Sauce
There’s a printable recipe card below with the method. But here are some step-by-step photos to show you how to make this cheese sauce gluten free.
Place a large saucepan on a low heat and melt the butter. Once melted, add the flour and use a whisk to mix together into a thick paste.
Pour in approximately 100ml of the milk and continue stirring until it forms a smooth, thick paste with no lumps.
Continue to add the milk, around 100ml at a time, stirring constantly. Each time, only add the next lot of milk when all the lumps are gone.
Once all the milk has been added, you should have a smooth, thick white sauce.
Continue to stir until it starts to bubble, simmer for 30 seconds, then add the cheese, nutmeg and a generous seasoning of salt and pepper.
Mix well until the cheese has melted and you have a smooth sauce, then remove from the heat and serve.
Storing and Freezing Instructions
TO STORE: This gluten free cheese sauce can be kept in the fridge for up to 5 days. Cool to room temperature then decant into a tub and refrigerate. Reheat to eat.
TO FREEZE: Cool the cheese sauce to room temperature, portion into tubs and freeze. You can reheat it from frozen or defrost overnight first if you prefer.
TOP TIP: This gluten free cheese sauce will thicken a lot when it cools. It should thin out a little when reheating. Make sure you stir it well and add a little milk if needed.
