Creamy Vegan Potato Broccoli Casserole

Whether you serve them as a leftover dish, comfort food on Sundays, or as a crowd pleaser for family evenings: casseroles are a perfect dinner match for a lot of occasions. As a leftover dish, they are perfect for hiding all your leftover vegetabl under a crispy vegan cheese crust at the end of the week. As a cozy dinner, it warms from the inside and leaves a wonderful smell in your apartment. And as it's so easy to prepare in advance, you can feed a whole crowd with casseroles and make sure, that it will be ready just in time when they arrive.

We already have a recipe for a vegan potato casserole with vegan "minced meat" on the blog, but today we add a green version to it: a vegan potato and broccoli casserole. It's easy to prepare and you can of course adjust the vegetables according to the season. If you want an extra crispy vegan cheese topping, turn on the grill function of your oven in the last minutes of baking (but always keep an eye on the casserole so it does not burn).

The creaminess is provided by a simple vegan cream sauce, which we prepare in a small pot beforehand. We recommend using oat or soy-based heavy cream for this which you can find in almost every supermarket. Make sure to use a heavy cream for cooking and not a vegan whippable heavy cream as they are often sweetened. You can also find vegan shredded cheese in a lot of supermarkets nowadays. We recommend you mix the cheese with some oil and water beforehand as this will help with melting in the oven (we included the instructions in the recipe below).
