Cheesy Chicken Southwest Pasta Casserole

Cheesy Chicken Southwest Pasta Casserole 1Happy Friday, ya’ll! Yesterday I woke up thinking it was Friday. Realizing it was actually Thursday was a REAL buzz kill. A few choice words may or may not have been said. But, today, I can say with 94% accuracy that it is in fact Friday.

Let the angels sing.

Lately, I’ve been feeling under the weather. My stomach has been hurting and my abs have been aching. I think the 100 degree weather + no a/c is to blame. It feels like I’m being killed very slowly and painfully. Pretty sure this is what hell feels like.

I don’t really feel like eating anything at all either. Well, anything healthy. On Wednesday I made some mini brownie bites and ate approximately 31. Then I made another batch of this and ate it all with a bunch of those soft pocketless pita things. {The person who invented those deserves a medal.} Then I had 7 bowls of cereal and some diet root beer and called it a day. {Not together.} I did manage to eat a handful of grapes and some deli turkey at some point. And drank a few glasses of water. And had this for dinner.

{Remember my post about how I eat? YEAH. I’m such a healthy poster child. —>LIES.}

Why I chose to cook AND turn the oven on to make this in this heat is beyond me. Did I take crazy pills this morning? All signs point to yes.

I was lightheaded and delusional. Clearly.

So, this dinner. It’s amazing. My husband could not rave enough about this. We’re kind of a southwest freaks, so of course we enjoyed every last bite. I packed it full of veggies in an attempt to make myself feel less guilty about eating half the pan. And make up for all the cheese. And chips. Didn’t really work considering my previous consumption of 17,000 calories earlier in the day. Oh well. There’s always tomorrow.

Moral of the story: make this.

Also, I like food. But I think you knew that already.

Here’s how to do it: Start by cooking some whole wheat pasta part way. You’re going to be cooking this whole thing in the oven later, so you don’t want your pasta to turn into mush.

I think the chips on top were my favorite part. Love the textural difference. Oh, and the corn. It was super sweet.

We ended up LOVING this {my husband especially} and thoroughly devoured the leftovers yesterday. Here’s the printable:

Have a great weekend!


Cheesy Chicken Southwest Pasta Casserole

Yield: 4 generous portions


  • 1/2 pound whole grain pasta such as rotini
  • 4 tablespoons butter
  • 1 1/2 cups diced onion
  • 1 large clove garlic, minced
  • 1 green bell pepper, diced
  • 1 red bell pepper, diced
  • 2 jalapenos, seeded and chopped
  • 3 ears of corn, kernels removed
  • 1/4-1/3 cup all purpose flour {depending on how much liquid the veggies give off}
  • 2 cups chicken stock or milk
  • 2 teaspoons ground cumin
  • 1 teaspoon chili powder
  • salt & pepper, to taste
  • 1/3 cup heavy cream
  • 1 cup grated cheddar cheese
  • 1/2 cup grated mozzarella cheese
  • 2 cups chopped rotisserie chicken
  • 1 1/2 cups crushed tortilla chips


  1. Start by boiling a large pot of water and cooking the pasta for half the time recommended on the box. Drain and set aside. In the same hot pot, melt butter and saute onions, garlic, peppers, jalapenos and corn until tender, 7 minutes or so. Sprinkle in flour and stir. Cook 2 minutes, then pour in chicken stock or milk. Increase heat to thicken sauce, then sprinkle in cumin, chili powder, salt, pepper, cheeses, cream, chicken and cooked pasta. Stir to combine and pour into large casserole dish. Top with crushed tortilla chips and bake at 350 degrees for 20-30 minutes or until hot and bubbly. Serve.
  2. Recipe Notes: I used chicken stock, but feel free to use milk to make a creamier sauce. Also, I ran out of cheddar cheese so I didn't top my casserole with more cheese but would have liked to. If you wanted to be really crazy, top the chips with more cheese and salsa to get some nacho action. Holy guacamole that would be good.

  9. Our air went out too… we stayed with my sister because I couldn’t bare the heat!

  10. This looks SO good! Quick question though. Do the chips on the top get soggy while baking?


    • Mine did a little bit, but nothing I couldn’t handle. 🙂

  11. From the moment I saw this I knew I had to try it and I did! It was delicious, thank you for sharing your amazing recipes!!! Yes you deserve the triple exclamation points and a smiley face 🙂

  12. YUM!

  13. Wow! I found this recipe in google today and wanted to cook something special for the family tonight. That was awesome, even my kids who are usually picky eaters when it comes to peppers, onions, etc. were begging for more. Great recipe, you made one families night!


  14. I found your recipe while browsing Pinterest for something to make for dinner that included the left over rotisserie chicken from Costco we had for dinner a few nights ago. . I must say it was amazing! The hunny even said that this was definitely one of his top ten favorite dinners, score!! 🙂 🙂 🙂

    I do have to admit that I did make some changes per our tastes, and what I had on hand..

    First off, I used 1 can of corn, 1 can of green chilies, 1 can of tomatoes with green chilies, 1 can of olives, as well as the onion and garlic.

    Also I didn’t have any heavy cream on hand, and lets face it after the holidays, who needs all the extra calories :). So instead I substituted 1 can of fat free cream of chicken soup. Then at the very end i realized that I didn’t have any corn chips on hand. But I did find some long forgotten flour tortillas. Soo I cut them up intro strips and covered the top with them and then covered the whole mess with more cheddar cheese! The addition of flour tortillas was, I think, the best part! They got nice and golden brown and crispy

    . YUM!! Im still sooo full from my two big helpings at dinner. But now after typing this my mouth is watering for more! Thank you for the delicious recipe. It is most definitely a new favorite in our house hold

  15. This is WITHOUT A DOUBT my family’s favorite recipe!! I have cooked it so many times now that I don’t even have to look at the recipe! I was never a big fan of bell peppers but I cook them down enough and it taste AMAZING!! You, my dear, are a genius!!!

  16. I made this last night and it was terrific. I used greek yogurt to creamitize the sauce and it worked great! I added a little more sharp cheddar cheese and used mini macaronis instead and called it Mexican Mac’n’Cheese so my boys would eat it. Thanks for sharing. 🙂

  17. This looks sooooo yummy!!! I’m definitely trying this out for dinner tomorrow!

  18. I made this tonight for dinner. I used milk with a bit of chicken bouillon granules mixed in. I also used prepared spicy pico de gallo in place of the veggies and added half a can of drained corn to make things even more simple. It turned out delicious! Thanks for the recipe Lauren. 🙂

  19. I tried this recipe (with a few tweaks) and it turned out AMAZING. I was out of tortilla chips and heavy cream, so I used Panko bread crumbs and half and half instead. I also opted to used canned mixed veggies (I know, the shame!) instead of bell peppers and that would be my only regret. They mushed together a tad and I’m sure fresh peppers would have been much better. Anyway, thanks for the awesome idea!

  20. Do you think it would be okay to use cornflour instead of flour? And vegetable stock instead of chicken stock? And how much milk/cream is really needed? Wondering if I need to buy a container or I can just steal a splash from a friend, haha. Thanks!

    • I’ve never used corn flour before, so I’m not sure about that one, BUT the vegetable stock is ok and you probably only need a splash or two of cream!!

      • Great! Thanks – I’ll definitely be giving this a try soon! : ) Though I’ll be using a British microwave/convection oven for the first time, so fingers crossed.

  21. Found your recipe on Pinterest and knew it was destiny that I make this recipe. I do not regret my decision — so, so, so good! I didn’t have any fresh corn so I used a bag of frozen that I’d defrosted in the refrigerator overnight. I’d also chopped the peppers about a week before and had them frozen, defrosted them, ended up using the entire 1/3 c. flour because of all of the water the peppers gave off. It turned out perfect. Even my boy who is sensitive to stuff that is ‘spicy’ asked for a second helping.
    It is definitely going in to the rotation!

  22. Have made this recipe over and over it is one of my favs! Is a little time consuming but worth it!

  23. Hey Lauren,

    I first made this recipe 2 years ago, followed by many other times. (bookmarked it), now I made it again tonight. Still one of my favorites. So delicious, and the wife and kids love it and beg me to make it! Thanks!!!!
