Tuna Noodle Casserole from Scratch is Always Best!

Recently my tastebuds traveled back to my mom’s classic tuna noodle casserole of the 70s and 80s. My flashback made me want to replicate and enjoy this comforting dish immediately.

My mother always cooked everything from scratch, so her tuna noodle casserole recipe was no exception.

Instead of canned cream of mushroom soup, this recipes uses a simple sauce of butter, milk, seasonings, and mushrooms. It’s thickened with cornstarch so the sauce is naturally gluten free.

Tuna Noodle Casserole from scratch can be made with traditional egg noodles, or swap them out for gluten free penne.

How To Make Tuna Noodle Casserole From Scratch

1. Sauté the fresh mushrooms and onions in butter until vegetables are soft. Make sure you’re using a big enough pot to add in 2 cups of milk. 
2. Add the milk and seasonings to the pot. Bring to a boil and then add cornstarch mixed with chicken broth. Cook until thickened.

Tips for Making Tuna Noodle Casserole From Scratch

• Be careful to not overcook the pasta! Anytime you bake a dish with gluten free pasta, do not boil the noodles long. Boiling for half the time called for al dente ensures the pasta doesn’t become mushy during baking.
• Rinsing the gluten free noodles in cold water after boiling helps to stop the cooking. Otherwise they will steam and cook more while waiting to be mixed with other ingredients.
• Don’t forget to cook hard boiled eggs ahead of time. The easiest and foolproof way to boil eggs is with an egg cooker. If you aren’t a hardboiled egg fan, you can leave them out. 
• If you aren’t gluten free, this recipe will work with regular egg noodles too. Use a 12 ounce package and boil them to almost cooked through before mixing with the sauce and other casserole ingredients.
