The BEST Microwave Chicken Casserole with Ritz Crackers

by Stephanie

This Microwave Chicken Casserole with Ritz Crackers is the ultimate comfort food. It’s cheesy and creamy and just hits the spot when you want some comfort food. Plus, it reheats beautifully, so you can make lunch or dinner for the whole week with one dish. 

I have made it probably a million times both in the oven and in the microwave.  I taught my daughter, who is currently in college, how to make it, and it’s one of her go to recipes for making a meal up ahead of time. She makes it for dinner and then divides up the rest for a few lunches or dinners throughout the week. 

If you aren’t careful, you’ll end up eating the whole thing in one day, or you can get about 4-6 meals from this one casserole. This casserole is perfect to take to lunch and heat up in the microwave at school or work. 

The thing I like about this microwave chicken casserole is that it’s so simple and quick to put together. You can literally make the entire thing in the casserole dish — just one dirty dish!   

The BEST Microwave Chicken Casserole with Ritz Crackers

While the orzo pasta is cooking in the microwave, I prepare the chicken.  Sometimes I’ll use leftover rotisserie chicken and eyeball it to be about a cup or 1 1/2 cups.  If I don’t have any fresh chicken, I’ll use a big can of chicken, tuna, or turkey. 

I don’t like the smell from canned chicken, so I drain it and rinse it in cold water in a colander until I can’t smell that strong chicken or tuna smell.  One can about 12.5 oz is perfect for this dish. 

How to make a Microwave Comfort Chicken Casserole

Then, I pour a can of cream of chicken soup on top of the chicken.  Next, I fill the empty can of soup about halfway with milk and pour that over the casserole.  Then, I top it in shredded sharp cheddar cheese.  We like the zing from the cheddar, but you can use any cheese like swiss or mozzarella.  

Lastly, I melt some butter and crush up some ritz crackers and mix together.  You can use saltines or any other crackers for this, but I like the buttery-ness of Ritzs.  Just sprinkle it over the top.  

Since everything is already cooked in this casserole, it’s just a matter of melting it all together.  I like to cook it until it’s bubbly on the sides, which is about 5 minutes in the microwave.
