Our old-fashioned Tuna Casserole recipe is simply the best, made with noodles, a creamy white sauce, tuna, peas, and celery, and baked with crushed crackers on top.

I promise this Tuna Casserole is better than Grandma's.
This recipe is proof that you can elevate even the most old-fashioned casserole recipes by making them with better ingredients, and from scratch.
Instead of using canned soups, we make a quick creamy white sauce. We boost the flavor with sautéed peas, celery, and onion, and don't forget to use good quality white albacore tuna. It may cost a bit more, but the quality really makes a difference in taste! You can use egg noodles for tuna noodle casserole, but we prefer medium shells since each one fills with the creamy sauce.
How to make Tuna Noodle Casserole:
Cook noodles according to package instructions.
Sauté Veggies: Melt butter in pan. Add celery, onion, peas, and garlic and sauté for a few minutes.
Make Sauce: In a separate pot, make a roux by melting the butter and then whisking in the flour. Cook for a minute or two. Gradually pour in the chicken broth and milk, whisking until smooth. Keep stirring constantly until it bubbles and thickens. Add lemon juice, salt, dill, parsley, and parmesan cheese.

Combine: Add cooked pasta, sautéed vegetables, and tuna to the sauce and mix to combine. Pour into a baking dish and top with cheese and crushed crackers.

Bake at 350°F for 25-30 minutes or until hot and bubbly.
Make Ahead and Freezing Instructions:
To Make Ahead: Sauté the veggies, make the sauce, and cook the noodles. Store everything in separate containers in the fridge until ready to assemble the tuna casserole.
To Freeze: Cook the noodles so they are slightly undercooked. Follow the recipe and assemble casserole (don't add cracker topping) in a freezer-safe container or disposable aluminum pan. Cover well and freeze for up to 3 months. Thaw overnight in the refrigerator then sprinkle with crushed crackers and bake until hot and bubbly.

I promise this Tuna Casserole is better than Grandma's.

I’m back to make your tuna noodle again. Tastes like the comfort food my family loves, but with out the cans. Thank you!
Fab recipe! I did add sautéed mushrooms and some cheddar cheese. Thank you!
This was excellent; I used 2 cans of tuna, one yellow and one wild tuns. I did not make the sauce, used canned mushroom soup thinned with chicken stock. I topped the cassarole with thin slices of tomatoes, sprinkled a blend
of 3 cheeses (mexican) and lightly topped all with panic flackes..
Oh, so good! I’ve messed up so many times trying to figure out how to make this from scratch! Eureka. You did it! Thank you.
Amazing, the best tuna noodle casserole I have ever made and I’m as old as dirt.
I’ve made this several times now and it is winner! I add about 1 tbs of Worcestershire and 1 tsp sirachi for a little tang and zing, and paprika for color on the topping. A knockout recipe.
This is a wonderful recipe but your suggestion to add Worcestershire and Sriracha intrigued me so I gave it a try. WOW! Spot on.
Worcestershire and sriracha are amazing additions to this dish! It was so savory and beyond the normal flavors of the tuna noodle casserole that I grew up with! 5 stars!!
This was terrific! I added a can of mushroom soup, half white cheddar/half Parmesan and some white pepper for a kick.
Holy moly this was amazing! The perfect dish after a long day on the lake. It was more time and work that I have ever put into a tuna-noodle-anything before but totally worth. Only variation was adding a chopped jalapeño without the membrane and seeds for a slight kick. Thank you for sharing!
Outstanding! Used soda crackers instead of Ritz and spinach instead.of.oeas other than that this recipe is absolutely amazing! Thank you! It’s a definite keeper!
Best tuna noodle casserole I have ever had! Definitely a Winner in my book!
