Chicken Fajita Pasta is the kind of one skillet dinner that packs all the best Tex Mex flavors into a cozy bowl of creamy noodles. You get juicy chicken, sweet peppers, and golden onions tucked in a rich cheesy sauce that hugs each piece of pasta. My family always requests this when they want something both comforting and a little exciting on a weeknight.
When I first made this, my kids devoured it and asked for seconds which never happens with anything green in it so now it is on our regular dinner rotation.
Ingredients
- Rotini pasta: gives the sauce something to hold on to with all those spirals. Pick a whole wheat if you want more fiber
- Bell peppers: bring gorgeous color plus natural sweetness. Go for crisp vibrant ones without blemishes
- Yellow onion: gives a mild, slightly sweet background and helps build a savory base
- Boneless chicken breasts: soak up the spices and cook fast. Choose firm fresh chicken with no odor
- Heavy whipping cream: creates the creamy rich sauce. Look for one with no stabilizers for the smoothest finish
- Cheddar cheese: melts into the sauce for classic sharp flavor. Monterey Jack or a pre-shredded Mexican blend work too
- Fajita seasoning packet: saves time and brings consistent zesty flavor. Opt for low sodium if you can find it
Step-by-Step Instructions
- Cook the Pasta:
- Boil a large pot of salted water. Add rotini and cook according to package directions until just al dente about 8 to 10 minutes. Drain and set aside but keep a cup of the pasta water to help bring the sauce together if needed
- Sauté the Vegetables:
- In a wide skillet heat olive oil over medium high. Add sliced bell peppers and onions. Cook stirring for about three minutes until the edges are just softened and lightly golden. This gives the dish those sweet fajita notes
- Cook the Chicken:
- Add diced chicken breasts right to the same skillet. Sprinkle over the fajita seasoning. Stir well so every piece is coated and let it cook for seven to eight minutes. The chicken should be firm and browned and the inside should have no pink left
- Make the Sauce:
- Lower the heat to low. Pour in heavy cream. Use a wooden spoon to scrape up all the browned bits stuck to the bottom of the pan this is what gives fajitas their signature flavor. Let the cream simmer for about two minutes until gently thickened
- Add Cheese and Finish:
- Sprinkle in the cheddar cheese. Stir until completely melted and the sauce is smooth and thick. If it seems too thick add a splash of pasta water
- Combine and Serve:
- Add the drained pasta to the pan and toss everything together thoroughly so each piece is coated in the creamy cheesy sauce. Taste and add more salt or a squeeze of lime juice if you like. Serve right away for best texture

Cheddar cheese is my favorite part because it brings just the right sharpness and melt to the sauce. The first time I made this I watched my husband go back for thirds after swearing he was full and it still makes me smile
Storage Tips
Store any leftovers in an airtight container in the fridge for up to three days. Reheat gently on the stove over low heat with a splash of milk or broth so the sauce gets creamy again. Avoid microwaving at high heat which can separate the cheese sauce
Ingredient Substitutions
You can swap the chicken for shrimp or sliced steak if you want a different protein. Use your favorite color peppers or even add mushrooms to boost the veg. Blend in a handful of spinach during the last minute on the stove for a green pop
Serving Suggestions
Serve with a sprinkle of extra cheddar or fresh cilantro on top. Warm up some tortillas and scoop the pasta inside for a Tex Mex inspired pasta taco. A simple salad with lime vinaigrette makes a fresh crunchy side
