This is a straightforward weeknight recipe that marries Tex‑Mex flavors with a one‑skillet pasta finish. It’s built around a quick fajita marinade, a fast sear of chicken, a soft sauté of onions and peppers, and then a no‑fuss pasta finish right in the same pan. No separate sauce to babysit; everything comes together in one pot for a satisfying, colorful dinner.
I rely on short ingredient lists and clear steps when I’m cooking after a long day. The technique here is practical: marinate briefly, sear the chicken for texture, soften the veggies, then use broth, tomatoes, and milk to finish the pasta so it absorbs flavor as it cooks. Topped with salsa and sour cream, it’s familiar and bold.
You’ll get simple swaps and timing tips throughout the post so you can adapt it to what’s in your fridge. Read through the notes, then follow the steps under “Ready, Set, Cook” — I keep that ordered list exactly like the tested recipe so you can cook with confidence.
What Goes Into Chicken Fajita Pasta
At its core, Chicken Fajita Pasta uses a classic fajita marinade to flavor both chicken and vegetables. The acid (lemon juice) and oil carry the spices (cumin, garlic powder, onion powder) while fresh minced garlic layers on top. After searing, you cook the pasta in a mixture of low‑sodium chicken broth, milk, and undrained diced tomatoes so the noodles pick up the savory, slightly tangy sauce.
Key components: boneless skinless chicken for quick cooking; onion and a mix of bell peppers for texture and color; penne for a reliable bite that captures sauce; and pantry staples — broth, milk, canned tomatoes — to pull everything together without extra steps. Salsa and sour cream are optional finishers that add brightness and creaminess at the table.
Ingredients
- 2Tablespoonsoil(vegetable or canola oil) — for the fajita marinade; helps carry spices and tenderize the chicken.
- 3Tablespoonslemon juice — acid in the marinade to brighten flavor and help tenderize.
- 1-2clovesgarlic, minced — fresh garlic for the marinade; gives aromatic depth.
- 1teaspoonground cumin — warm, earthy fajita note.
- 1teaspoongarlic powder — reinforces garlic flavor without burning when searing.
- 1teaspoononion powder — rounds out the spice mix for savory balance.
- pinch of salt — a basic seasoning; adjust to taste.
- freshly ground black pepper — for a little heat and aromatics.
- 1poundboneless skinless chicken breast halves or tenders — the main protein; cooks quickly and slices easily.
- 1Tablespoonolive oil — for searing the chicken and sautéing vegetables.
- 1wholeonionchopped — sweetness and structure; softens during sauté.
- 1green bell pepper, chopped — classic fajita vegetable; adds color and crispness.
- 1red bell pepperchopped — sweeter pepper, balances the green.
- 1-2clovesgarlic, minced — for the vegetables; adds fresh garlic punch.
- 2cupslow-sodium chicken broth — cooking liquid for the pasta; keeps sodium in check while adding flavor.
- ½cupmilk — adds creaminess to the cooking liquid and softens the tomato’s acidity.
- 14.5ounce candiced tomatoes, undrained — the tomato element for body and brightness; undrained juice contributes to the sauce.
- 8ouncesPenne Pastas, regular or whole wheat — the pasta component; penne holds sauce well.
- ½teaspoonsalt — added to the cooking liquid to season the pasta as it cooks.
- salsa and sour cream, for topping, if desired — optional finishers that add freshness and cooling creaminess.
Chicken Fajita Pasta, Made Easy
Make this recipe easier by prepping before you start: chop the peppers and onion, mince the garlic, and measure the broth and milk. Use zip‑top bags to marinate — they save on cleanup and help the flavors coat evenly. While the chicken marinates, you can set the table or prepare any toppings like salsa and sour cream so the final assembly is simple and fast.
This recipe intentionally uses a single large skillet for most steps. That means fewer dishes and one pan to heat, sear, simmer, and finish. The process is largely hands‑off during the pasta phase — once everything is combined and covered you can check on it rather than stirring constantly.
Why Chicken Fajita Pasta is Worth Your Time
It’s fast and flavorful. You get the char and texture of fajita‑style chicken and peppers with the comfort of a saucy pasta, but without juggling a separate sauce. The pasta absorbs the seasoned cooking liquid so the flavor is integrated rather than just coating the noodles.
It also scales well. The technique is the same whether you stretch it for two or four people, and the ingredients are flexible enough to adapt to what you have on hand. For busy nights, that combination of speed, flavor, and minimal cleanup is huge.
International Equivalents
While this dish is Tex‑Mex inspired, the idea of marrying spiced, sautéed proteins and vegetables with pasta appears in many cuisines. Think of it as a Southwestern riff on creamy chicken pasta. If you prefer, swap the cumin for smoked paprika and the lemon for lime for a slightly different regional profile, or replace penne with short tubular pasta common in Mediterranean kitchens for a similar result.
Essential Tools for Success
- Large heavy skillet with lid — roomy enough for searing and one‑pot pasta cooking.
- Sharp chef’s knife and cutting board — for even, quick chopping of onion and peppers.
- Measuring spoons and cups — to keep the marinade and liquids consistent.
- Zip‑top bags — easy, quick marinating and minimal cleanup.
- Instant‑read thermometer (optional) — to check chicken reaches 165°F for food safety.
- Spatula or tongs — for turning chicken and stirring the pasta.
Things That Go Wrong
Underseasoned pasta: if you skimp on the salt in the cooking liquid, the final dish will taste flat. Salt the liquid as directed and adjust at the end if needed.
Soggy chicken or overcooked vegetables: cook chicken just until 165°F and remove promptly. If you leave it in the pan while cooking the vegetables and pasta, it can dry out. Transfer chicken and loosely cover as the recipe instructs.
Pasta too firm or too mushy: follow the 13–15 minute guideline but check at 12 minutes if your stove runs hot or your skillet is thinner. If the liquid is fully absorbed and the pasta is still underdone, add a splash of hot water or broth and continue cooking briefly.
How to Make It Lighter
Use low‑fat milk instead of whole milk for a lighter finish, or skip the sour cream topping. Choose whole wheat penne (the ingredient list notes that option) for extra fiber. Trim any visible fat from the chicken and use the lower amount of oil in the marinade if you want to reduce calories. Finally, serve a generous salad on the side to balance the plate with non‑starchy vegetables.
Chef’s Rationale
Short marination flavors the chicken and the vegetables without needing hours. A quick sear on hot oil adds Maillard browning and texture; finishing the chicken off the heat prevents overcooking while the pasta simmers. Cooking pasta directly in a flavored broth with canned tomatoes concentrates flavor into the noodles themselves rather than relying on a separate sauce — it’s efficient and tasty.
The dual use of fresh minced garlic and garlic powder ensures garlic flavor is present at different stages: the fresh garlic gives immediate aromatic punches, and garlic powder lends a background savory note that stands up during cooking. Lemon juice brightens the marinade so the dish doesn’t taste heavy.
Shelf Life & Storage
Refrigerate leftovers in an airtight container and consume within 3–4 days. Reheat gently in a skillet with a splash of broth or milk to loosen the pasta and restore creaminess. Avoid reheating repeatedly.
Freezing is possible but note texture changes: the sauce can separate and the pasta may soften. If you plan to freeze, consider freezing the cooked chicken and vegetables separately from the pasta and liquid for better texture when thawed and reheated.
Questions People Ask
- Can I use frozen peppers? — Yes, but thaw and drain well; frozen peppers release more water so sauté a little longer to evaporate excess moisture.
- Can I swap chicken for beef or shrimp? — The technique works for other proteins, but cooking times will change; adjust accordingly.
- Is it okay to use low‑sodium broth? — The recipe calls for low‑sodium chicken broth so you control the salt; taste and adjust at the end.
- Can I make this dairy‑free? — Substitute a non‑dairy milk (unsweetened) if desired; texture and flavor will differ slightly.
- Do I have to marinate? — The brief marinade adds flavor but you can season directly if time is tight; the difference is noticeable but not essential.
Ready, Set, Cook
- In a small bowl combine the fajita marinade: 2 Tablespoons oil (vegetable or canola), 3 Tablespoons lemon juice, 1–2 cloves garlic (minced), 1 teaspoon ground cumin, 1 teaspoon garlic powder, 1 teaspoon onion powder, a pinch of salt, and freshly ground black pepper to taste.
- Place the chopped chicken in one large zip-top bag and the chopped onion and bell peppers in a second large zip-top bag. Pour half of the marinade into the chicken bag and half into the vegetable bag. Seal each bag and toss to coat. Refrigerate for 15 minutes or up to a few hours.
- When ready to cook, heat 1 Tablespoon olive oil in a large skillet over medium-high heat until hot.
- Remove the chicken from its bag and discard any remaining marinade from the chicken bag. Add the chicken to the hot skillet and cook about 3–4 minutes on the first side. Flip and continue cooking until the chicken is cooked through (internal temperature 165°F). Transfer the chicken to a plate and loosely cover with foil.
- Add the marinated vegetables (including their minced garlic) to the same skillet and sauté for a few minutes, until tender. Transfer the vegetables to the plate with the chicken.
- In the same skillet add 2 cups low-sodium chicken broth, ½ cup milk, the 14.5-ounce can diced tomatoes (undrained), 8 ounces uncooked penne pasta, and ½ teaspoon salt. Stir to combine and bring to a boil over medium-high heat.
- Once boiling, cover the skillet, reduce the heat to medium-low, and cook 13–15 minutes, until the pasta is tender and the liquid is mostly absorbed.
- Return the cooked chicken and vegetables to the skillet and stir to combine. Heat until everything is warmed through.
- Serve immediately, topped with salsa and sour cream if desired.
