This easy recipe for gluten free tuna casserole skillet is made completely from scratch, no canned soup needed. Canned tuna, peas, and gluten free pasta come together in a homemade, creamy sauce for a healthy, comforting dinner dish.
I like to use my twelve inch cast iron pan to make this recipe, since it heats so evenly and goes straight from stovetop to oven. If you don't have one, a stovetop pan and a 9x13 baking dish work just as well.

Made from Scratch, No Canned Soup
This tuna casserole skips the canned cream of mushroom soup entirely. Instead, it starts with a simple homemade roux of butter, gluten free flour, broth, and milk, which gives you full control over the ingredients and flavor. Since most canned condensed soups aren't reliably gluten free anyway, making the sauce from scratch is the easiest way to know exactly what's in your dinner.
How to Store and Freeze
Store leftovers in an airtight container in the fridge for up to 3 days. To freeze, let the casserole cool completely, then wrap tightly or store in a freezer safe container for up to 2 months. Thaw overnight in the fridge before reheating in the oven.
Top Tip
If you don't have a cast iron skillet this recipe for gluten free tuna casserole skillet can also be made in a 9x13 baking dish. If you are using a baking dish you will need to make the sauce on the stovetop and then add the sauce, peas and noodles to your oven safe dish for baking.
Frequently Asked Questions
I love to cook with cast iron. It evenly heats and is easy to clean. I like to use this Cast Iron Skillet Cleaner Chainmail Scrubber. I rinse the pan with hot water to remove any loose food and leftover oil. Then I use the chainmail scrubber to lift up any bits of food left.
I place the pan on the stove top at medium heat and let it dry completely. Then I pour a tablespoon of oil on the pan and carefully rub it onto the entire inside of the pan with a paper towel. Remove the skillet from heat and it's ready for your next meal.
Remember to never put your cast iron skillet into the dishwasher.
I'm a big fan of gluten free brown rice pasta. I like how well it holds up to being baked and doesn't get soggy. I also think brown rice pasta has a nice texture and is the closest thing I've found to regular wheat pasta.
Some of my favorite brown rice pasta brands are: Jovial or Tinkyada,
This recipe skips canned soup entirely in favor of a homemade roux, so there's no need to hunt for a gluten free canned soup substitute. If you'd like to make it dairy free, swap the butter for a plant based alternative and the milk for unsweetened plain non dairy milk.
