Today I don’t have Thai food for once 😀 I love casserole. Unfortunately, I rarely make them and I don´t know why. Basically, casseroles are quick to make and it´s also a great way of using up leftover potatoes. In addition, this variation is good as meal prep because if you make a complete casserole, this is enough for a few days.

How to make a vegan cheese sauce

This time I wanted to try a special casserole since I have only tried vegan cheese once before (as a nacho dip), I thought this would be another great opportunity. In fact, this vegan cheese is healthy. I am completely fascinated by what you can prepare with e.g. cashew nuts. You can try so many different things with spices as well as healthy ingredients. That’s why I find vegan cooking so exciting.

The vegan cheese, therefore, consists of cashew nuts. It is important that you soak the nuts in water beforehand. It would be best to soak them the previous evening so that they have a perfect consistency the next day. But if you want it to go fast, it is enough to soak the cashew nuts for about 3 hours. You’ll also need vegetable stock, nutritional yeast (very important for the cheesy taste!), 1 onion, tapioca starch, 1 garlic clove, and salt. You have to mix it all together until it has a creamy consistency. This sauce is really quick to make and healthy!

Easy and delicious preparation of this vegan cheesy potato casserole

The most time-consuming part is actually to cut the raw potatoes but otherwise, everything is prepared very quickly and you just have to put the casserole into the oven. Unfortunately, this takes a little longer, however it’s still worth it! 🙂

I love broccoli very much and the combination with vegan cheese is very delicious! Additionally, I cut pieces of the leek into it, because I am also a big fan of these vegetables. In my opinion this is the perfect combination for a casserole.

Besides, I like the fact that this recipe works completely without cream. At first, I didn’t really know how to make a casserole without cream. Is there any of you who cannot tolerate cream? Unfortunately, it´s the same with all the vegan alternatives. I usually have stomach pain after consumption.… Moreover, the avoidance of cream makes the casserole even healthier!
