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.

My mom made her tuna casserole with canned cream of mushroom soup, a few of cans of tuna, and noodles.

My favorite part of the casserole was the buttery bread crumb topping which I would pick off and eat first.

Flash forward about 25 years and I have to say my tuna casseroles have come a long way.

Forget the canned soup, I make my own sauce which is a buttery blend of onions, cream, milk, nutmeg, garlic powder, and thyme.

The sauce takes just minutes to make and it 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 the crisp buttery topping.

    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.

  2. Michelle Trent

    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.
