Ingredients You’ll Need
- 1½ pounds boneless & skinless chicken breasts: Chicken breasts are the base of this dish, providing lean protein that stays juicy when slow-cooked. You can substitute with thighs for a richer flavor.
- 1 teaspoon salt: Essential to bring out the flavors of the chicken and veggies.
- ½ teaspoon black pepper: A dash of pepper adds a nice kick without overpowering the other spices.
- 1 1 ounce fajita seasoning packet: This seasoning blend gives your pasta that recognizable fiesta flair. Feel free to use homemade seasoning if you have a preferred blend!
- 1 red bell pepper, sliced: Adds sweetness and color. Green bell peppers can be used as a substitute, though red is sweeter.
- 1 green bell pepper, sliced: A touch of freshness that balances the richness of the cream.
- 1 small onion, sliced: Sautéed onions lend a touch of sweetness and depth to the dish.
- ½ cup chicken broth: Keeps the chicken moist while infusing flavor into the pasta. Low-sodium options work well for better control of saltiness.
- 1 (10 ounce) can tomatoes with green chiles, drained: These provide a zesty and slightly spicy note; diced tomatoes can be substituted if needed.
- 3 cloves garlic, chopped: Fresh garlic elevates the dish with a fragrant aroma.
- 1 cup heavy cream: This makes the sauce luxuriously creamy and coats the pasta beautifully. Half-and-half can be a lighter alternative.
- 12 ounces penne pasta, cooked: Penne’s shape holds onto the cream sauce nicely; feel free to use your favorite pasta instead.
- 1½ cups shredded Mexican-blend cheese: Melts beautifully to create a cheesy finish. Opt for cheddar or Monterey Jack for a different flavor.
How to Make Crockpot Chicken Fajita Pasta

- Season the Chicken: Generously season 1½ pounds of boneless, skinless chicken breasts with 1 teaspoon salt, ½ teaspoon black pepper, and the fajita seasoning packet. Make sure the spices are evenly distributed for maximum flavor.
- Layer the Veggies: In your slow cooker, place the sliced red and green bell peppers along with the sliced small onion at the bottom. This acts as a flavorful bed for the chicken.
- Add the Chicken: Place the seasoned chicken breasts right on top of the peppers and onions, ensuring they cover the surface.
- Pour in the Broth: Add ½ cup of chicken broth over the chicken to infuse moisture as it cooks. Cover with the lid and set your slow cooker to LOW for 4–5 hours. You’ll know it’s done when the chicken is tender and shreddable.
- Shred the Chicken: Once the cooking time is up, shred the chicken directly in the slow cooker using two forks. This saves you from dirtied dishes.
- Mix in the Cream: Stir in 1 cup of heavy cream until everything is combined and creamy. The rich texture makes every bite incredibly satisfying.
- Incorporate the Pasta and Cheese: Lastly, mix in the cooked 12 ounces of penne pasta and 1½ cups of shredded Mexican-blend cheese. Stir until everything is thoroughly mixed and the cheese has melted into that beautiful, creamy sauce.
Storing & Reheating
To keep your Crockpot Chicken Fajita Pasta fresh, store any leftovers in an airtight container in the fridge for up to 3 days. You can also freeze it for up to 3 months; just ensure it’s cooled before transferring it to a freezer-safe container. When ready to enjoy again, reheat in a microwave, stirring occasionally, until hot throughout (about 2-3 minutes). The texture may soften slightly, so adding a splash of cream or broth can help refresh it.
Chef’s Helpful Tips
- Avoid overcooking the chicken; it should be tender but not dry. Keeping an eye on the slow cooker makes a difference.
- Ensure the cream is at room temperature before adding it; this prevents curdling when mixed with hot ingredients.
- If you prefer a spicier dish, add a diced jalapeño or extra fajita seasoning to the chicken.
- For a thicker sauce, consider adding a cornstarch slurry just before mixing in the cream for the last step.
- This dish can be made a day ahead. Just reheat gently to avoid drying it out.
Crockpot Chicken Fajita Pasta brings together the smoky spices of fajitas with the comforting texture of pasta, creating a delightful meal that your family will adore. I’m sure you’ll appreciate the simplicity, and it’s versatile enough for anyone to enjoy! Feel free to switch up ingredients based on your pantry or preferences. Whether you’re cooking for a crowd or just yourself, this recipe lets you savor bold flavors without the fuss.
