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.

Gluten Free Dairy Free Tuna Noodle Casserole Recipe

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.
