Any time I can serve a dish that combines pasta, cheese and chicken, it’s bound to be a hit at my house. This Tex Mex White Chicken Spaghetti was no exception. Everyone loved it and came back for seconds!

Rotel tomatoes, chili powder, cumin and cayenne give this savory pasta dish it’s Tex Mex flare.

Add as much or as little cayenne as you like. I usually add just pinch, but if you like things really spicy, feel free to add more.

And the white cheddar cheese makes for a more elegant looking, restaurant quality dish. This isn’t just another mac and cheese dinner, that’s for sure!

You can use white or whole wheat spaghetti in this dish, and linguine or even fettuccine also work well.

I like to top things off with some chopped fresh tomatoes and cilantro.

This recipe makes plenty to serve a crowd, but it can easily be halved to serve four or fewer people.

I made this on a night when two of my boys were gone, and there were enough for three of us to enjoy it for two days!

For extra convenience, I used a supermarket rotisserie chicken, but you can certainly cook and shred your own chicken. I’m all about convenience though.

Just one more reason I love this easy dinner–it was on the table in less than 30 minutes!

Delicious, quick and easy, and loved by everyone who tried it. This Tex Mex White Chicken Spaghetti is a winner in my book, and we’ll definitely be having it again soon.
