Hachiiiis! I often make hachis Parmentier at home, and we just love it, but I never really thought about posting the recipe, to be honest... In truth, this is just one version of the many I make regularly. This hachis Parmentier is made from textured soy protein. It's inexpensive, completely neutral in flavor, making it super easy to adapt to any seasoning, and it's becoming more and more available everywhere (in bulk, at organic shops, and sometimes even in supermarkets...).
For this recipe, I wanted to show you the simplest and most basic way to make this hachis, but I also invite you to customize it however you like, for example by adding mushrooms (just add them to the pan right after the onion, between step 3 and step 4). I also enjoy replacing the soy protein with crumbled Beyond Meat sausage, it's super tasty!
