Chicken Fajita Pasta (One Skillet, 30 Minutes)

The first time I made this, I was standing over the stove trying to decide between fajitas and a pasta bake, and I just… didn’t decide. Chicken went in the skillet with fajita seasoning like it was going on a tortilla. Then the cream and cheese showed up like they’d been invited the whole time. Nobody complained.

This is a one-skillet dinner. Chicken, peppers, onion, and pasta all end up in the same pan, and the sauce comes together from what’s already in there — no separate roux, no second pot for the noodles if you time it right.

Why This Works

Fajita seasoning is built for a dry sear — chili powder, cumin, and paprika bloom in fat and stick to the chicken. If you dump it into a wet sauce from the start, it turns muddy instead of toasted. Searing the chicken and vegetables first, dry, is what keeps that smoky edge instead of just tasting like seasoned water.

The other thing that matters is the cheese timing. Dump fiesta blend into a hard boil and it breaks — you get grease pooling instead of a sauce. Bring the broth and cream to a low boil, then drop the heat before the cheese goes in. Melt it on a simmer, not a boil, and it stays smooth.

Ingredients

• 1.5 lbs chicken breast, diced
• 1 tsp garlic powder
• 1 tsp onion powder
• Black pepper, to taste
• 1 packet fajita seasoning
• 1/2 bell pepper, diced (any color)
• 1/2 sweet onion, diced
• 1 cup heavy whipping cream
• 1 cup chicken broth
• 1½ cups fiesta blend cheese (or cheddar)
• 8 oz penne, cooked and drained
• Oil, for the pan

Instructions

1. Heat a little oil in a large skillet over medium-high and add the chicken.
2. Sprinkle the garlic powder, onion powder, black pepper, and fajita seasoning over the chicken and stir to coat.
3. Add the bell pepper and onion. Cook everything together, stirring occasionally, until the chicken is cooked through.
4. Pour in the chicken broth and heavy cream. Stir to combine.
5. Bring the mixture up to a low boil.
6. Stir in the cheese and let it melt.
7. Drop the heat to a simmer and let the sauce thicken for a few minutes.
8. Add the cooked, drained penne and toss to coat.
9. Serve right away.

Tips

• Dice the chicken evenly, or the smaller pieces overcook while the bigger ones are still pink in the middle.
• Cook the pasta while the chicken and vegetables are working — one less thing waiting around to get cold.
• If the sauce looks thin after the cheese melts, give it another minute or two on the simmer instead of adding more cheese. More cheese just makes it grainy.

Variations

Swap the penne for rotini if that’s what’s in the pantry — the ridges hold the sauce fine. I tried this with rice instead of pasta once and would skip that again; the sauce needed the starch from the noodles to cling right, and it just pooled at the bottom of the bowl with rice.

Pepper jack instead of fiesta blend adds real heat, not just color — worth it if the fajita seasoning you’re using runs mild.

Make-Ahead

The chicken and sauce hold up fine in the fridge for a day or two, reheated gently on the stove. Don’t cook the pasta ahead and store it in the sauce — it keeps absorbing liquid and turns mushy by the second day. Cook the noodles fresh and stir them into reheated sauce instead.

Closing Thoughts

This one reheats better for lunch the next day than most cream sauces do, since the fajita seasoning holds its flavor even after a trip through the microwave. Good with a side of charred corn if you’ve got the stove space for it.
