Gluten-free Béchamel Sauce with oat-milk (Oatly brand)

I had a request from a viewer to share how to make a gluten-free béchamel sauce using oat milk. This simple recipe uses olive oil, white rice flour, tapioca flour, and oat milk, plus a touch of spice, mustard, and nutritional yeast for extra flavour. You can also add parmesan cheese or butter if preferred.

This creamy gluten-free white sauce is perfect for lasagna, pasta bakes, or drizzling over vegetables. I love using Oatly oat milk, as it's made from gluten-free oats for a smooth, dairy-free alternative. Try this easy plant-based béchamel sauce as a staple in your kitchen!

My go-to oat milk is the Swedish brand Oatly—one of the original and creamiest options, made with gluten-free oats. This easy plant-based béchamel sauce with oat milk is a staple in my kitchen and perfect for use in meals every week.
