Oh, Gluten Free Cajun Smothered Green Bean Casserole, I Just Can’t Keep You to Myself Any More…Nope…

Y’all, I could honestly spend at least an hour of time telling you all about my love of Cajun smothered green beans.  I love them so much that I wrote an entire blog post about them, when I gave my cherished recipe away to the entire Internet world.

Since I spent at least a decade of my life perfecting my green beans recipe, my fondness for them only takes a backseat to one other recipe: My Trinity Roux™.  But, that’s a whole other story

And, since I’ve published my Cajun smothered green beans, it’s been the #1 recipe on my blog. So, I know that y’all love the highly seasoned, buttery, melt-in-your-mouth south Louisiana dish as much as I do. Yep.

Well, I actually developed this gluten free Cajun smothered green bean casserole recipe more than 2 years ago. I have a vivid memory of making them for a family get-together at Mark’s parent’s house. And afterwards having a conversation with Mark about how I usually always bring green beans to almost every event.

He was very polite when he said that maybe people would want another one of my side dishes, sometimes, you know, instead of the green beans. This was quite a shocking statement to hear, y’all. Because I buy green beans almost every single time that I go to the grocery store. And, when I’m making dinner plans, I usually think I want to cook something or other ‘and green beans.’

And then when we get invited to any kind of potluck, I think that I want to bring green beans. And then when I have a good meal at someone else’s house, I think ‘the only thing that would’ve made that meal any better would’ve been smothered green beans.’

I know, I know, I’m obsessed with green beans. But it’s a good obsession, as I don’t believe that a green bean has ever really hurt a person at all. Nope.

And, I do believe that when you take something you love and make it even better, then it’s time to share it with those who will love it as much as you do. Yep. So, here I am sharing my gluten free Cajun smothered green bean casserole with y’all right here, right now…

This Gluten Free Cajun Smothered Green Bean Casserole is South Louisiana Food Love at Its Finest…Yep…

The most important thing  that I learned growing up in a south Louisiana Cajun household is this: Food is love, love is food, and food that you cook from your heart means all that much more when you share it with those you love. Yep.

So, my own love of the Cajun food culture is soooo strong that gluten intolerance didn’t keep me from it, it drew me closer to it. Yep again.

Nowadays, it’s soooo easy to find gluten free cream of mushroom soup at your local grocery store. It’s usually right next to the gluten free flour mixes, so in one quick trip you can have everything you need to make this yum-delicious gluten free Cajun smothered green bean casserole. You can usually also order all the ingredients online, and have them packed and ready for you when you get there. Or, you can have it delivered straight to your home.

Anyway, my oh sooo tender and flavorful Cajun smothered green beans form the base of the dish. Then, a mixture of cheeses, a few spices, and the GF cream of mushroom soup inject the beans with a ‘I-just-gotta-have-one-more-bite’ creamy texture. And the homemade gluten free French fried onions, y’all. A few spread into the casserole to enliven the flavor. And then some placed on top for picture-perfect presentation and over-the-top crunchiness.

Share this gluten free Cajun smothered green bean casserole with those you want to food love with south Louisiana-seasoned, side dish yum-deliciousness. And see y’all on the yum side…
