I Love The Mexican Twist On This Chicken Alfredo Recipe

So dreamy, so creamy, sooooo delicious! I ♥ my Mexitalian fusions!

Oh, heeeeey, friends! Happy Sunday! Welcome to my allthethings pasta/chicken sanctuary. Err. Blog. 

I had an email the other day from a reader asking me to STOP butchering “their” Italian cuisine, referring to my Mediterranean White Chicken Enchiladas.

Normally, I wouldn’t bring this up because then you and I would have something/someone to gossip about, however, this one is an exception.

An exception because, a) since when is Italy the only thing that is Mediterranean?
Geography 101: The countries with coastlines on the Mediterranean Sea include; Albania, Algeria, Bosnia, Croatia, Cyprus, Egypt, France, Greece, Israel, Italy, Lebanon, Libya, Malta, Morocco, Monaco, Montenegro, Northern Cyprus, Palestinian territories, Slovenia, Spain, Syria, Turkey, and Tunisia.

AND, b) Imagine what would have been if Picasso went along with the norm and continued to just draw stick-people.

Mmm’kay? Cool.

This Creamy Alfredo Is Pure Comfort Food

Thus, today we’re talking about pasta and cumin and chili powder and bell peppers and other yummy stuffs. Food for the heart and soul.

This whole thing was like a delicious fusion of all the things this family of 4 loves. From the cavatappi pasta to the southwestern flavors, this recipe represents!

I also found out that this is very good for the truly hungry-hungry. Like, the hangry hungry. <— Me, every day. It gave my hungry self a feel-good hug at the end of a long, exhausting day full of me taking care of two little girls and their stomach bugs. Grrrrr! GO AWAY WINTER!

But, for reals. I just love this Southwest Chicken Alfredo combo. It’s colorful, it’s loaded with flavor, it’s creamy, it’s full of texture and there’s avocado on top. I mean. What more do you need?!

Have a Happy Sunday!!

  1. This looks delicious, but I think you must have omitted the pasta when you tabulated the nutritional information. There’s no way that a serving only has 11 grams of carbohydrate! A pound of pasta divided into 6 servings would yield 2.66 ounces per serving which equals over 56 grams of carbohydrate just from the pasta! That would also add over 200 calories. If only pasta calories didn’t count. 🙂

      Thank you so much for catching that!! Truly. The nutritional facts calculator had calculated the pasta as “instant yeast”… no idea why. Reason I didn’t see it is because this recipe is from 3.5 years ago, before nutritional facts calculators were available for online recipe boxes. Again, thank you. I updated the info. 🙂

  2. My grandson’s girlfriend has been asking for spicy chicken alfredo. I went searching and typed in spicy chicken alfredo and your recipe came up. Guess what we’re having for dinner tonight??!! She’s really excited!

    This recipe looks delicious! Can we substitute the half-and-half with evaporated milk or regular milk?

      Hi Stephanie!! I haven’t tried it with evaporated milk, so I’m not exactly sure. I don’t want to say go ahead and then have it not turn out for you. But you can definitely use regular milk. It won’t be as creamy, but it will work. I hope that helps. Let me know if you tried it!

    Um, no, please don’t stop. I love it when you mingle one cuisine with another. It makes it that much more fun, not to mention flavorful. Love this dish. Pinned.

    Gahhh, comments like that annoy me so much! People take food way too serious sometimes.

    This looks delicious though! I fully support you “butchering” whatever cuisine you want!

    This looks amazing! Winter does need to go away! Too much cold, too much snow! Avocados help.

  7. Lol about the Italian cuisine thing. It’s much more fun to mix cuisines isn’t it! This looks great 🙂 I’m usually not attracted to dishes with cheese sauce (I do love cheese!) but I’m going to give this a try 🙂
