This post contains affiliate links. Before we knew we had food intolerances, I loved Tuna Noodle Casserole. I gave it up when I, and then the whole family, went gluten and dairy free. However, I just missed this meal too much. I went to work in the kitchen and came up with this yummy Gluten Free Dairy Free Tuna Noodle Casserole recipe.
The whole family loves it! As an extra bonus, it’s a fairly inexpensive meal, which, as you likely know, is not the case for most gluten free, dairy free meals.
Just an FYI, if you have a growing family like we do with teens and preteens that are ravenous, you may want to double this recipe. I double it now every time I make it, and our family of 5 usually eats all of the doubled recipe. Leftovers now are a thing of the past.
How to Keep the Cost Low
Buying allergen-friendly food can be expensive! I keep the cost low for this recipe in a few different ways.
Trader Joe’s is my place to go for brown rice pasta as it’s only $1.99 per 16 ounce bag. I also buy my mayonnaise there as I find it’s cleaner than other types of mayonnaise.
We get tuna in bulk at Costco. It runs about a dollar a can, and the ingredients are clean.
I try to get my Bob’s Red Mill 1-to-1 flour at Big Lots or VitaCost, but you can also buy it at Amazon.

This sounds really good! We’ve recently started a grain free diet for the next 4 weeks and then transitioning over to gluten free. My kids love tuna noodle casserole, so I will have to give this a try once we’re eating grains again. It sounds great! I’d love to invite you to come by and share this blog post on my blog hop, Get Real Frugal Friday! http://realfoodrealfrugal.com/2013/01/18/get-real-frugal-friday-blog-hop-2/
I just made tuna noodle casserole earlier this week. I have never seen a recipe that didn’t use canned, cream soup so this is very interesting. It’s probably much healthier.

I love this recipe! It’s perfect for my ridiculous food allergies but the family loves it too. I just have one question. How much celery? I do not see it listed in the ingredients.
It needs 3 stalks celery. Thanks for catching the omission. I’ve added it to the recipe!
