Ingredients You’ll Need
- 1½ pounds boneless & skinless chicken breasts: The star of this dish. You can also use chicken thighs for extra moisture.
- 1 teaspoon salt: For seasoning the chicken, enhancing all the other flavors.
- ½ teaspoon black pepper: A simple yet essential spice that balances out the flavors.
- 1 1-ounce fajita seasoning packet: Brings that authentic fajita taste; adjust the amount based on your spice preference.
- 1 red bell pepper, sliced: Adds sweetness and vibrant color.
- 1 green bell pepper, sliced: Contributes a slightly tangy flavor and more color.
- 1 small onion, sliced: Introduces a savory depth; vidalia or yellow onions work well too.
- ½ cup chicken broth: Keeps the chicken moist and flavorful during cooking; vegetable broth is a tasty alternative.
- 1 10-ounce can tomatoes with green chiles, drained: Adds a zesty kick; you can use fresh diced tomatoes if preferred.
- 3 cloves garlic, chopped: For aromatic flavor—fresh is best, but jarred can work in a pinch.
- 1 cup heavy cream: For that luscious, creamy consistency; half-and-half is a lower-fat substitute.
- 12 ounces penne pasta, cooked: The perfect pasta shape to hold all that sauce; you can swap it with your favorite short pasta like rigatoni or rotini.
- 1½ cups shredded Mexican-blend cheese: Ensures the dish is creamy and cheesy. Feel free to use cheddar or a more “traditional” cheese for a different flavor profile.
How to Make Crockpot Chicken Fajita Pasta

- Season the Chicken: Start by seasoning the chicken breasts generously with 1 teaspoon salt, ½ teaspoon black pepper, and the entire packet of fajita seasoning, ensuring it gets that flavorful kick.
- Layer the Vegetables: Add the freshly sliced red and green bell peppers along with the onion to the bottom of your slow cooker, creating a colorful base that enhances the dish.
- Top with Chicken: Place the seasoned chicken breasts directly on top of the veggies in the slow cooker.
- Add Broth: Pour in ½ cup chicken broth around the sides of the chicken, then cover and cook on LOW for 4–5 hours, until the chicken is tender and easily shreddable.
- Shred the Chicken: Once cooked, shred the chicken directly in the slow cooker using two forks. It should fall apart effortlessly.
- Stir in Cream: Mix in 1 cup of heavy cream, letting it blend beautifully with the chicken and vegetables.
- Add Pasta and Cheese: Finally, stir in the cooked 12 ounces of penne pasta and 1½ cups of shredded Mexican-blend cheese, mixing until everything is thoroughly coated and the cheese is melted.
Storing & Reheating
Once the Crockpot Chicken Fajita Pasta cools down, transfer it into an airtight container and store it in the refrigerator. It lasts up to 4 days and warms up nicely. For longer storage, you can freeze it; just be sure to do it in a freezer-safe container for up to 3 months. When reheating, pop it in the microwave for about 2-3 minutes or until heated through, adding a splash of chicken broth or cream to refresh the texture if needed.
Chef’s Helpful Tips
- Make sure you don’t overcrowd the slow cooker; it can prevent the chicken from becoming tender.
- If you prefer a thicker sauce, reduce the chicken broth slightly or add less cream—this will create a more concentrated flavor.
- For added spice, consider incorporating sliced jalapeños or a dash of cayenne.
- Pre-cooked chicken can be used for a faster option, but reduce cooking time accordingly to just heat through.
- If your pasta soaks up too much sauce upon reheating, you can always add a little more cream or broth to revive it.
The lovely fusion of flavors in Crockpot Chicken Fajita Pasta brings satisfying warmth to your table. With each heaping plate, you’ll experience a wonderful blend of comfort and spice. Feel free to experiment with additional toppings such as fresh cilantro, sliced avocados, or a squeeze of lime juice for an extra pop!
