Chicken Fajita Pasta
Chicken Fajita Pasta with onion, bell peppers, and a creamy cheese sauce is an easy weeknight dinner for two made from scratch or with leftover chicken.
This Chicken Fajita Pasta is inspired by a long lost recipe from my recipe binders.
Growing up I had three thick binders plus a few skinny ones. As I cooked throughout college, I printed recipes and stored them in my binder along with magazine pages I tore out.
I made this chicken fajita pasta recipe a lot and remember my mom even requested it a few times when I would cook at home for them.
Soon after college graduation when I started my night shifts at Target, I lost a lot of my joy.
Finding a degree-worthy job while cleaning up after slobs and being yelled at because you don’t know what color the filing cabinet is in the box or whether the wrinkle free sheets are truly wrinkle free doesn’t exactly leave you inspired to do much.
However, those binders meant a lot to me and as I moved on to my big girl job in 2010, I packed those binders as is. They sat on my shelf as my cookbook collection grew. Then I got my iPhone and started digitizing my recipes.
Now in 2021, I condensed everything down to one binder. It’s been used so much over the years, the cover is starting to fall off.
One day, I needed a recipe in my binder. As I turned the pages, I found all kinds of recipes I used to make, including my creamy Chicken Fajita Pasta made with heavy cream.
I was so excited I couldn’t wait to share it with you. Chicken Fajita Pasta is an easy chicken pasta recipe with a Tex Mex twist.
You toss some penne with fajita spiced chicken, sweet bell peppers, onion, mushrooms, cilantro, lime juice, and a creamy cheese sauce.
It’s the flavor of chicken fajitas with an Italian twist of pasta.
What are chicken fajitas?
Chicken fajitas are a Tex-Mex dish of grilled chicken with a fajita seasoning rub, colorful sweet bell peppers, and onions.
You can then serve them in tortillas like my Air Fryer Chicken Fajitas or over lettuce like my Chicken Fajita Salad.
You can also make steak fajitas with beef instead of chicken.
Fajitas don’t technically have mushrooms, but I love them so much I added them to my chicken fajita pasta recipe. I mean, it’s not like pasta is traditional Tex Mex either.
What are the ingredients in Chicken Fajita Pasta?
The ingredients for this Chicken Fajita Pasta recipe are:
- Penne pasta: I like penne the best because the tubes hold the sauce, but you can use another similar shape, such as rigatoni, ziti, or even elbow.
- Boneless skinless chicken: I love dark meat and prefer using 2 small chicken thighs. However, you can also use 1 large chicken breast. You can also use leftover chicken.
- Fajita seasoning: This is where most of your flavor will come from! You can make your own mix (recipe included) or buy a store packet to help save time.
- Oil: This is for frying the chicken and veggies. Flavor doesn’t matter too much, so I recommend vegetable, canola, or olive oil.
- Sliced onion: White or yellow onion work best.
- Sliced mushrooms: I used white button mushrooms, which are the most common at grocery stores. Buy whole ones and slice them yourself. Sometimes the pre-sliced mushrooms are too thick.
- Sweet bell pepper: You want either red, orange, or yellow bell pepper. Green isn’t as sweet and therefore not recommended for fajitas. You only need one pepper, so you can pick one color or use a little of all three.
- Minced garlic: I love garlic too much to not include it.
- Milk: Whole milk is ideal because the more fat, the creamier the sauce will be. However, you can use what you have in the fridge.
- Heavy cream: Also helps make the sauce extra creamy. You can also use half and half instead of both milk and heavy cream.
- Salt: Salt helps bring out the flavors of each ingredient. I prefer using kosher, but you can also use table salt. Make sure you taste and adjust as you cook.
- Shredded cheese: I used a Monterey jack cheese blend, but you can also use cheddar cheese.
- Cilantro: Every Tex Mex dish needs cilantro! Of course as long as you don’t find it tasting like soap.
- Lime juice: Acidity is what makes the cream sauce go from flat to great.
How To Make Chicken Fajita Pasta
First, bring a large pot of water to a boil for your pasta. Wait until it starts boiling to add a handful of salt.
If you salt it beforehand and the water boils away before you’re ready, the water reduces and may become too salty.
This is especially useful if you have trouble timing your dishes and you’re not ready to add the pasta.
Once it’s boiling, add the pasta and cook until al dente, about 10 minutes.
While the water is heating, cook your chicken in a large 12 inch skillet. Trust me – you’ll need the room to cook your vegetables.
When one side is brown (about 3-4 minutes), flip then cook the other side until brown and no longer pink in the middle (about another 3-4 minutes).
Transfer your chicken to a bowl and keep warm.
Next, add your onion, bell pepper, and mushrooms to your pan, scraping up the brown bits left behind from the chicken. This will add extra flavor!
Once softened, add your milk and heavy cream. Bring to a boil. It’ll start to foam up, so don’t leave your skillet unattended. Stir often.
After a few minutes it should start to thicken slightly. Turn down the heat then stir in your cheese until melted.
Stir in your chicken (plus any juices from the bowl), cilantro, and lime juice. Taste and adjust for salt if needed.
At this point, the sauce should be thick enough. If it’s too thin, cook for a few more minutes. If it’s too thick, stir in a little more milk.
By now your pasta should be done cooking, so toss it with your sauce. Your dinner is now ready!
How To Make Chicken Fajita Pasta With Leftover Chicken
I included instructions on how to cook chicken, but what if you have leftover chicken ready to go?
Easy! Toss your chicken with fajita seasoning then skip the cooking. At the end, stir in your leftover chicken and heat until warm.
Are fajitas served for cinco de mayo?
I know chicken fajita pasta isn’t a recipe you’d normally see for cinco de mayo given it’s both pasta and Tex Mex, but the flavors are reminiscent of a fiesta.

At this point your sauce should be done. However if it's too thin, cook for a few more minutes. If it's too thick, stir in more milk.

How cool that this is an old favorite! It sounds soooo yummyy!
I’m always looking for different pasta recipes and this is one I’m adding to my to-cook list. How great to combine Mexican and pasta. So glad you dug out this old recipe to share today.
What a unique spin on the flavors of fajitas! I really love the idea of this dish…especially since I love cheese…and fajitas! Putting this on my to-make list for sure!
I love chicken fajitas, though I haven’t had them in years. This is such a great twist on them!
I eat a lot of pasta since living alone, and really put anything on it as a sauce. Anything. This is exactly the kind of dish I would make and eat with a tortilla, and then use leftovers with pasta. It sounds unbelievably good, love it! I keep recipes torn from magazines in boxes, but not binders. I should take the time to put them individually in plastic, so much easier to find.
So, I have to pretty much quadruple this. But, we’re having it tuesday. Soooo…woot!
Carla, this is just amazing. And totally up our alley as far as our love of all things pasta goes. AMAZING!
I have a recipe binder, too. Matter of fact, it could use some organization. I love the idea of fajita pasta. I can’t wait to make it. Pinned!
This sounds and looks so delicious! I must admit, that thinking of adding in pasta with Mexican food makes my mouth water even more… yum!!! ;-)
What a fun combination of flavors!
Amazing! All the flavours in here are delicious, I would totally make this with shimp too
I can’t wait to try this dish! I love fajitas, what a great idea to make them in to pasta.
What a clever idea! It’s so fun to discover old recipes and bring them back. I sometimes get so excited about all the new recipes, I forget to go back and make the oldies but goodies. This has inspired me to search through the archives.
I love that you still have your binders of recipes. I have a ginormous one that keeps getting fatter and fatter. Quite frankly, it doesn’t even close anymore. It drives my husband nuts when he sees it. I like knowing that recipes are online or on my computer, but there’s just something special about having paper pages to flip through, y’know?
This looks amazing! My mouth is watering! Great combo’s! Thanks for sharing.
What a festive, fun, flavorful dish! Love this!
Yum! That looks awesome!!! :-) I love chicken fajitas and then add noodles?! Sign me up!
This looks so tasty! I’m with you on the recipe-binder love! I know that I COULD digitize them now, but there’s something I love so much about being able to flip through them :)
Love this as a pasta dish, Carla!
Save me a plate! :)
Great recipe. love the twist with the pasta!!
I also used to keep a recipe binder with plastic sleeves. . I was quite obsessive about it.
I love this! what a great idea! I love a good pasta and this looks deliciously flavorful!
Made this without the heavy cream mushrooms & chicken since I didnt have and we still enjoyed it. Just wondering calories for 1 serving
I’m not a nutritionist so I don’t provide calorie info (esp since it sounds like you made adjustments, so it wouldn’t be accurate anyway). I know you can search for calorie calculators and enter what you used. I believe My Fitness Pal is one people use a lot.
Carla, II use minced garlic more than mincing. How much minced garlic constitutes a garlic clove?
You can use as much garlic as you’d like! The back of your jar should tell you how much is in a clove. I believe it’s about 1/2 teaspoon, but you can certainly bump it up to 1 teaspoon if you love garlic like I do.
Oh my gosh! This was so quick. easy and delicious!! Thank you!!
Glad you enjoyed it!
