Tuna Casserole Recipe For One

This wonderful tuna casserole is made with a rich and creamy homemade sauce, noodles, and just 1 can of tuna. It's the ultimate single serving comfort food!

When I was growing up, tuna casserole was a meal my mom made often. It was simple, inexpensive, and it was a meal she could put together quickly.

Tuna Noodle Casserole 

My mother's version of tuna casserole was made with canned tuna, canned cream of mushroom soup and noodles.

My version of tuna casserole is just as easy but I don't use canned soup. Instead I make a creamy sauce which is a buttery blend of onions, cream, milk, nutmeg, garlic powder and thyme.

The sauce takes just minutes to make and tastes incredible. So worth the extra few minutes of stirring on the stove. It's creamy, savory, and cheesy.

This mini tuna casserole has all the flavors I've always loved in a tuna casserole, including a crisp buttery topping.

    I usually use egg noodles but the elbows were a nice twist. I also enjoyed the flavor of the sauce. i added mushrooms towards the end in with the tuna, sauce, and pasta. I really liked this recipe. Thanks!

    Instead of noodles, I use 1 cup of cooked brown rice. It works well and adds a slightly chewy texture to the casserole. Delicious!

  3. Tried this recipe didn’t change a thing. This is winner winner tuna di ner. I love all your recipes I have tried. I can get two meals out of each recipe.

    Made this yesterday for hubby. He finished it off today. He said it was really good. I had to modify it some but, hey, couldn’t be all that bad since it’s all gone right?! One of the modifications was cooking it all in a small cast iron skillet. From start to finish. I was surprised that it fit in my Nu Wave oven but happy it did😃. I am sooo happy to find you & your recipes. Hopefully there will be fewer leftovers now. 💛

    I follow you on Pinterest and was wondering if you could use frozen tuna in this recipe. I’ve made several of your recipes & enjoy them being single doesn’t need to be boring ty.

    1. Gloria, Although I haven’t used frozen I don’t see why there would be any problem with using it. Just be sure to thaw and drain out any water that remains.

    I think I’ll try this tonight after my zoom meeting. I’ll probably use egg noodles though…not a big fan of elbow Mac.
