- 1 lb chicken tenderloins: Tender and quick-cooking, ideal for a juicy protein base.
- 1 bell pepper, sliced: Adds crispness and a sweet pop of color.
- ½ onion, sliced: Brings a mild sharpness that complements the spices.
- 1 (1.12-oz) package fajita seasoning: The secret blend that infuses the chicken and veggies with Tex-Mex flair.
- 1 Tbsp vegetable or olive oil: For sautéing everything to perfection and adding a touch of richness.

How to Make Chicken Fajita Alfredo Recipe
Step 1: Cook the Pasta
The foundation of any great Alfredo dish is perfectly cooked pasta. Start by preparing the penne pasta according to the package instructions until it is al dente. Drain it well and rinse quickly with warm water to stop the cooking process and keep it from sticking. Set it aside while you prepare the flavorful topping—it’s quick and easy.
Step 2: Season the Chicken and Veggies
Next, it’s time to bring on the bold fajita flavors! Cut the chicken tenderloins into bite-sized pieces so they cook evenly and soak up more seasoning. Sprinkle the chicken, bell pepper slices, and onion slices evenly with the fajita seasoning. This step infuses every bite with that signature Tex-Mex zest that makes this dish stand out.
Step 3: Sauté Everything Together
Heat your oil in a large skillet over medium-high heat until shimmering. Add the seasoned chicken, peppers, and onions in one layer. Cook them for about 7 to 10 minutes, turning occasionally so the chicken gets a nice sear and the veggies become tender yet still vibrant. This is where the ingredients truly meld and develop their irresistible aroma.
Step 4: Create the Creamy Alfredo Sauce
Pour the heavy cream directly into the skillet with the chicken and vegetables. Bring it to a gentle boil, then reduce the heat and let it simmer for 3 to 4 minutes. As the cream thickens, sprinkle in the Parmesan cheese and stir well until the sauce becomes beautifully silky and coats everything with a rich flavor. Finally, toss in the cooked penne pasta and mix it to evenly combine all the elements into one harmonious dish.
How to Serve Chicken Fajita Alfredo Recipe

Garnishes
A sprinkle of fresh chopped cilantro or parsley adds a refreshing green contrast and a pop of freshness against the creamy sauce. For an extra kick, some sliced jalapeños or a dash of smoked paprika can brighten the flavors nicely. Don’t forget a wedge of lime on the side—its bright acidity complements the richness perfectly.
Side Dishes
This recipe shines best paired with simple sides that won’t overpower the main event. A crisp green salad tossed in a light vinaigrette offers a refreshing balance, while some warm garlic bread or tortilla chips bring a satisfying crunch and make for wonderful scooping. You could also serve it alongside Mexican-style street corn for an exciting flavor pairing.
Creative Ways to Present
For a fun twist, serve the Chicken Fajita Alfredo Recipe in individual mini cast-iron skillets or casserole dishes to keep it warm longer and give it a rustic, homestyle feel. Another idea is to layer the cooked fajita chicken and vegetables with pasta in a deep bowl and garnish with cheese and herbs for an inviting presentation that highlights all the vibrant colors and textures.
Make Ahead and Storage
Storing Leftovers
Place any leftovers in an airtight container and store in the refrigerator for up to 3 days. The creamy sauce may thicken in the fridge, but a little gentle reheating with a splash of milk or cream will bring it back to its luscious consistency.
Freezing
While this dish is best enjoyed fresh, you can freeze leftovers for up to 2 months. To freeze, cool the Chicken Fajita Alfredo Recipe completely, then pack it into a freezer-safe container. Keep in mind that the texture of the cream sauce might change slightly, so thaw it overnight in the fridge before reheating.
Reheating
Reheat leftovers gently on the stove over low heat, stirring frequently. Adding a tablespoon or two of milk or cream will help loosen the sauce and restore its creamy texture. Avoid microwaving at high power as it can cause the sauce to separate.
FAQs
Can I use a different pasta shape for Chicken Fajita Alfredo Recipe?
Absolutely! While penne is ideal for holding onto the rich sauce, you can swap in fettuccine, rigatoni, or even farfalle depending on your preference or what you have available.
Is there a way to make this recipe lighter?
Yes, you can substitute half-and-half or whole milk for the heavy cream and use less cheese to reduce calories. Keep in mind the sauce will be less rich but still flavorful thanks to the fajita seasoning and fresh vegetables.
Can I make this recipe vegetarian?
Definitely! Replace the chicken with sautéed mushrooms, tofu, or even extra bell peppers and onions. Season them with the fajita mix just the same for that smoky, spicy flavor.
What’s the best way to ensure the chicken stays tender?
Cutting the chicken into bite-sized pieces and cooking it over medium-high heat without overcrowding the pan helps it cook quickly and remain juicy. Avoid overcooking to prevent dryness.
Can I prepare the sauce ahead of time?
You can make the Alfredo sauce in advance and store it in the fridge for up to a day. Reheat gently before mixing with the pasta and cooked chicken to keep the sauce creamy and smooth.
