Microwave Cheesy Tuna Noodle Casserole

The casseroles come to me frequently when I go back to the dining hall during my undergraduate days. My favorites was the Cheesy Tuna Noodle Casserole and Turkey Tetrazzini. They were such heartwarming foods.

Did you know that a simple cheesy tuna noodle casserole may be prepared in a microwave? The most excellent part of this dish is that it reheats well. It is creamy and cheesy and such a comfort food. 

It is ideal to portion out for lunches to bring to school or work as well as leftovers to reheat in the microwave later.

How do you make Cheesy Tuna Noodle Casserole in the microwave?

This tuna noodle casserole and my microwave chicken casserole are extremely similar. However, fewer ingredients are needed.

You may omit the cream of chicken soup from this dish even though it is creamy and cheesy. 

I just blend cream or half-and-half with cheddar cheese in place of cream of chicken soup. First, microwave the orzo pasta in the casserole dish.

Once it is cooked, most of the water will be absorbed, so you won’t need to drain it.

After preparing the orzo, combining the ingredients is all that is required. 

To ensure that the cheese and cream melts while the orzo is still very hot, I like to add them first. The tuna should then be added and well mixed.

I smooth the casserole once everything has been combined. 

A cracker crust is an option for the top. We have a child at home who does not like the crust, but my college-age child does, so occasionally, I omit it.

Where to find Orzo Pasta?

Orzo pasta does not taste the same from brand to brand, as I have discovered. For this dish, if you’re fortunate enough to live in Texas and have an HEB nearby, buy the orzo pasta that they sell under their own brand. 

The finest one, indeed! The Barilla orzo pasta, which is available at Walmart, is my second favorite. Kroger’s orzo pasta is not my favorite; I’m not sure what the brand name is. It gets quite sticky and is much more costly.

Use rice instead of orzo pasta if you can’t locate it. It’s equally delicious and really simple to prepare in the microwave.
