Are you searching for a recipe on how to make béchamel sauce with oat milk? Here's my easy oat milk béchamel or white sauce great alternative for mac & cheese, lasagne or a pasta bake. I have been perfecting an oat milk béchamel sauce over the last year that I use in many of my quick dinner recipes. I still tolerate a little cheese so I mostly make this sauce including cheese. However, I have also made a vegan béchamel sauce by using dairy-free butter and nutritional yeast instead of cheese. I prefer drinking oat milk to any other plant-based milk as when I use it to cook with it is very similar to cow's milk.

My favourite oat milk is the Swedish brand Oatly, so creamy and one of the original and they make their oat milk with gluten-free oats*. This béchamel white sauce recipe with oat milk is one of my favourite ways to have an easy plant-based sauce to use every week.
