A Thanksgiving staple at the table is the green bean casserole – however, most use a canned cream soup. Once we started a gluten and dairy free lifestyle, I created a homemade version that was gluten and dairy free.

Thanksgiving is probably the easiest holiday to make a gluten and dairy free meal. Mostly, because it’s meat accompanied with various vegetables. When I am cooking for a large group, I don’t want to make two versions of the same meal. Therefore, through trial and error, I’ve worked to find recipes that everyone will love. This includes baked goods like cornbread and pumpkin pie. Success is when I’m able to make the same meal for everyone, and no one detects the gluten and dairy free elements.

homemade alternative to cream soup

This green bean casserole is one of those recipes. Plus, you’re making something without the additives that come with a canned cream soup!

Now, I can’t say this is as easy as opening a can of cream soup, however, you will love that it’s full of wholesome, pure ingredients. There’s nothing that says love like a homemade dish. And just for the record, this is now one of my kiddo’s favorite Thanksgiving recipes. She gave it a huge thumbs up!

Even better is that you can get most of the ingredients at Aldi, so it’s a inexpensive dish to make too! At this time of year, Aldi offers gluten and dairy free french fried onions.

Green bean casserole typically calls for soy sauce, but surprisingly, the first ingredient in most soy sauce is wheat. There is a gluten free version called tamari. Don’t have any? Skip it -I’ve made this dish without it and it’s still really good.
