Butter and milk are the key components of a traditional bechamel... Fortunately, with a couple of tweaks, you can make a simple vegan bechamel sauce quickly and easily

A bechamel sauce forms the base of many dishes. Lasagne. Cauliflower cheese. Pies. If you’re following a vegan diet, this is a major issue because pretty much every bechamel sauce recipe you come across is loaded with milk and butter. But that’s where my oat milk bechamel comes in handy.

Don’t worry! Just because this is vegan does not mean it is any less delicious. It is creamy, smooth and buttery but sticks to plant-based ingredients. Once you’ve made it, you can go ahead and use it how you would use a traditional dairy bechamel sauce.

What’s In Oat Milk Bechamel?

A traditional bechamel sauce is made of butter, milk and flour. We’ve got to make a few tweaks to this original recipe in order to make it completely vegan.

Ingredients for making vegan bechamel sauce
  • 40g Plain Flour: Flour is essential in a white sauce as this is what helps to thicken up the end result. You use the flour to make a roux.
  • 40g Vegan Butter: Any plant-based butter will work here. Olive oil spreads can work, too.
  • 500ml Oat Milk: I’ve opted for oat milk in this recipe but you can make a vegan bechamel with any plant-based milk.
  • Salt, Pepper and 1 tsp Nutmeg: Although you don’t NEED to include these, it’s always worth seasoning your bechamel before using it. I’ve included a pinch of salt, pepper and a little nutmeg.

Substitutes and Tweaks

You can even make this gluten-free by swapping out the plain flour for an equal quantity of chickpea flour.

Turn this white sauce into a vegan cheese sauce by stirring through 2 tablespoons of nutritional yeast.

If you’re a stickler for appearance, then you could use white pepper in place of the black pepper.

Stir through your favourite herbs or spices. Garlic powder, chopped parsley, paprika or chopped chives all work nicely.

How to Make Oat Milk Bechamel

Step 1: Melt the butter over medium heat in a large pan. The butter needs to be fully melted but don’t allow it to brown too much. The moment it has melted, move onto step 2.

Step 2: Add the flour to the butter and constantly stir it with a spatula, wooden spoon or whisk. You want to combine the butter and flour to turn it into a roux. You then need to cook it for 2 minutes or so until it is slightly brown. This is to cook the flour out a little.

Step 3: While constantly stirring or whisking, slowly pour in the oat milk. If you do it all in one go, you’ll end up with clumps and will have to work a lot harder to get a smooth sauce. Slow and steady is 100% the way to go here.

Step 4: Now is the time to season it. Add a pinch of salt, some black pepper and your nutmeg then stir it through the sauce.

Step 5: Turn the heat down nice and low and then cook the sauce for between 8 and 10 minutes until it has thickened up. You’ll want to keep stirring it at this point to prevent it from catching on the bottom.

Step 6: Once the sauce has thickened to where you want it, immediately remove it from the heat. You can then use it as you usually would in any recipe that calls for a white sauce or bechamel.

Here’s how to make a vegan white sauce without compromising on the texture

Ingredients

  • 40 g 40 Plain Flour

  • 40 g 40 Vegan Butter

  • 500 ml 500 Oat Milk

  • 1 Pinch 1 Salt

  • 1 tsp 1 Nutmeg

  • Pepper

Directions

  • Melt the butter in a saucepan over medium heat. Ensure it is completely melted but not browning or burning.
  • Add the flour to the melted butter, stirring constantly to combine them. This mixture is called a roux. Cook the roux for about 2 minutes until it is light golden brown.
  • Slowly add the oat milk to the roux, a little at a time, while constantly stirring. This will help to prevent lumps from forming.
  • Add the salt once all the oat milk has been added to the sauce. If desired, you can also add a pinch of nutmeg and some pepper at this stage.
  • Reduce the heat to low and continue to cook the sauce, stirring constantly, until it thickens. This should take about 8-10 minutes.
  • Once the sauce has thickened to your liking, remove it from the heat. Your oat milk bechamel is now ready to be used in your recipes.
