I find that Catelli gluten free pasta turns out well in the Instant Pot.  I make sure to always have some in my pantry.

To make this Tuna Casserole I brought a large pot of water to a boil and added the box of Catelli gluten free macaroni.

While the macaroni was cooking, for about 5 minutes, I prepared the rest of the ingredients for the base.

First I opened and drained 3 tins of flaked white tuna and dumped them into a large mixing bowl.  

Then I added one diced yellow onion, some Miracle Whip, almond milk, dijon mustard, minced garlic, dried parsley, salt and pepper.

I stirred all the ingredients together well.

Once the pasta was done cooking I drained the water and rinsed it well with warm water.

Then I added the pasta to the large mixing bowl.

I also added some frozen peas and shredded mozzarella, cheddar cheese blend.

After stirring in all these ingredients, until all were coated with the creamy mixture, I scraped everything into a greased 9 x 13″ baking pan.

For the crunchy topping I crushed a whole family size bag of Lays Dill Pickle potato chips right inside the bag.  No mess this way!

I sprinkled the potato chips very generously over the top of the casserole.

Then I placed the casserole in a preheated 400F oven for 18-20 minutes or until it was bubbling and the potato chips were brown.

Tuna Casserole is a staple in many households.  This gluten free version will not disappoint!
