I suppose deep down I knew that you could probably make oat milk at home, but I assumed it was a multi-step, multi-day pain, and that buying it at the store was infinitely easier. Well, firstly—things have changed. Secondly—it turns out it's not that hard.
We reached out the Chef Jefferson Alvarez (most recently the chef trying to save Papi's, but also of the beloved Cacao, amongst others) who was offering up his ultra simple recipe on Instagram. It turns out it's beyond easy.
1 cup large flake oatmeal
2 cups water
Mix together and let it sit at room temperature overnight. In the morning, add the mix to a blender (a Vitamix or a Breville Boss are a plus here) and blend at high speed (being careful to not heat mixture up) don’t let it heat up. Add 2 more cups of cold water and continue blending.
When smooth, pass mixture through a fine strainer twice (this helps keep a smooth texture).
Keep it refrigerated.
That's it. To see Jefferson himself do it click here and follow his Instagram video.
