My husband and I both grew up on casseroles as kids. Being kids in the eighties casseroles were a family staple. He fondly recalls a chicken and rice casserole his mom made for the family on a regular basis. I too recall my mom pulling a hot casserole out of the oven on Sunday evenings.

Casseroles are the ultimate comfort food; warm and creamy on the inside, crunchy and crispy on the outside. They beckon families around the table to share a meal and conversation.

What do plant-based vegans eat on Thanksgiving?

So, what could be better than a vegan potato casserole as the star of Thanksgiving dinner?

When I speak to friends and family about Thanksgiving dinner they always assume we eat Tofurky. That couldn’t be farther from the truth!

I can honestly say I have never tried Tofurky , so I can’t vouch for it one way or the other, but I don’t plan to serve it for Thanksgiving now or in the future.

I do, however, plan to create an absolutely beautiful whole food plant-based vegan Thanksgiving meal full of fall flavors that will leave even the non-vegans in my family full and satisfied without feeling like they’ve missed a thing.

Tools and Equipment You’ll Need to Make this Vegan Potato Casserole:

This vegan potato casserole is simple to make and you’ll need simple equipment to pull it together. To bake the casserole you’ll need a medium size casserole dish. I own a set of Corningware Casserole dishes that I got as a wedding gift many years ago. They have stood the test of time.

You’ll also need a high speed blender or a standard blender and a coffee grinder to make the vegan cream sauce. If you don’t have a high speed blender you can use a coffee grinder to finely ground the cashews.
