Let’s get cooking!
Are Au Gratin Potatoes Gluten Free?
The answer to this question is both yes and no. It all depends on the ingredients that are used to make the au gratin potatoes. While potatoes are definitely gluten free, some boxed Au Gratin Potatoes DO include gluten and many homemade recipes call for a flour roux or breadcrumbs on top. It is pretty easy, though, to tweak the recipe a bit and make your own potatoes au gratin at home.
The biggest two changes are:
- Make the roux with gluten-free flour. Some people are surprised to know that you can easily make a roux with gluten-free measure for measure flour. It’s a simple swap too – so 2 tbs flour would equal 2 tbs gluten-free flour.
- Either do away with the breadcrumbs altogether or use gluten-free bread to create the breadcrumbs.
Other than these two changes, you should be able to follow your favorite recipe as is.

A Note on Shredded Cheese
Why doesn’t pre-shredded cheese melt?
Have you ever used bought shredded cheese to use in a recipe and noticed that it didn’t melt well? That is because most pre-shredded cheeses contain ingredients that are meant to keep the shreds from clumping together in the bag.
But of course, in recipes like this one, we want the cheese to melt well with no lumpy chunks left behind. So here are my two suggestions:
- Get a block of cheese and grate it yourself right before you need it.
- Use Tillamook pre-shredded cheese. This is the only brand I have found that consistently melts evenly when heated.
Ingredients Needed
Before we get started, here is your grocery list for this recipe.
