This recipe for Crock-Pot Tuna Noodle Casserole has all the classic ingredients you’d expect but is baked in your slow cooker instead of the oven!

Slow Cooker Tuna Noodle Casserole
Tuna noodle casserole brings some back some fond memories from my childhood. There is just something comforting about a classic and creamy casserole that fills you up and is frugal too.
This tuna casserole recipe features egg noodles and tuna (of course) as well as cream of mushroom soup, milk, peas and pimentos.
Then the whole lot is sprinkled with cheddar cheese and bread crumbs for an irrestistable topping.
You see my mom made her tuna casserole topped with cheddar and bread crumbs.
My dad…Kraft American cheese slices and crushed potato chips.
I decided to present you with a casserole that was closer to my mom’s recipe.
But if you are feeling adventurous try the American cheese/potato chip version too.
All things in moderation folks!

Frequently Asked Questions
You can use any type of canned tuna in a tuna noodle casserole. I am kind of picky when it comes to tuna and prefer solid white albacore tuna. But it is more expensive than other varieties of tuna. For a more frugal alternative look into using chunk light tuna.
You will want your tuna to be packed in water not oil. However if all you have in the pantry is canned tuna packed in oil, you can drain off the oil, dump the tuna into a colander or strainer and rinse the oil off under warm running water in the sink.
If you don’t have diced pimentos on hand or cannot find them at your local grocery store you can easily omit them or instead of using frozen peas, pick up a bag of frozen peas and carrots instead.
While I think cheddar cheese is sort of a classic in and on top of tuna noodle casserole you can experiment with other types of cheese too. Some suggestions might be:
– Monterey Jack Cheese – Melts nicely with a mild flavor
– .American Cheese – My dad always added sliced American cheese on top of tuna noodle casserole. Yep…Kraft cheese slices. You could also use Velveeta for a really cheesy experience.
– Swiss Cheese – Would give an interesting tangy flavor.
– Pepper-Jack Cheese – Adding some spice to your tuna noodle casserole with some pepper-jack cheese would be fun!

I was just learning to cook in a slow cooker and this was my 2nd dish. It is so delicious! I’ve been making this type casserole for about 40 years, and must admit this recipe is the best one I’d had no would recommend this to anyone. Fast, easy and a great go to meal. Mine is only a 3qt so used a little less noodles, a litte extra soup and milk. It comes out perfect for me. Please try it!
We are so glad you enjoyed this Tuna Noodle Casserole Jody! Thanks for the rave reviews!
Can i pre make noodles, refridgerate and then make? I try to put meals together for my sons family who have no time beyond dumping in a crockpot and going.
Hi Kathy, yes you can pre-cook your noodles and refrigerate them. You may want to toss the hot noodles with a touch of butter or oil to prevent them from sticking together. But you can totally do that! Great idea!
