Where can you find 6 oz cans of Tuna? Those in the grocery are 5 oz packed in water and with a "drained weight" of 4 oz. "Shrinkafication"?

Hi 4Graces, I suggest doubling the suggested tuna and using two 5-oz cans.

I am not a connoisseur of the tuna casserole. I have eaten it as a kid but I have never made it myself. Mostly because my husband tells me he can't stomach it. That being said, I sure wish I could try this out! We drink soy milk in this house and I see that there is soy milk in the recipe. I've never heard of soy milk being used. I would LOVE to have those potato chips added on top as well! My nephew is coming to visit this summer and I think I will make this for him.

I make a couple of different kinds of tuna casseroles, but they are both baked versions. I love the idea of making tuna casserole in my slow cooker. I never thought to make cream of mushroom soup, so this is even more interesting. I never top my casserole with chips, and this sounds like a good final touch. Can't wait to try it!

Homemade mushroom soup would make this old favorite of mine only better. Although, since I seem to be having a love affair with mushrooms these days, I would definitely have to add a ton of sliced mushrooms sauteed in garlic and butter for more depth in flavor. And, I'm pretty sure instead of chips I'd use Ritz crackers mixed with butter and Parmesan. Come to think of it, I bet a little cheddar would be nice in this as well.

I love the combination of tuna and pasta and this recipe does exactly that. Cooking it in the slow cooker and the option to add whatever type of cream of soup I choose can also be substituted makes it more delicious. This recipe will be good on a busy day when it can be cooking while you're running errands or working and then sit down to this tasty dish.

I would wait until the casserole is nearly cooked to add the cheese so that it does not get too stringy before the pasta is tender.
