Ingredients
Protein and Seasoning
- 1½ pounds boneless & skinless chicken breasts
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 (1 ounce) fajita seasoning packet
Vegetables
- 1 red bell pepper, sliced
- 1 green bell pepper, sliced
- 1 small onion, sliced
- 3 cloves garlic, chopped
Liquids and Dairy
- ½ cup chicken broth
- 1 (10 ounce) can tomatoes with green chiles, drained
- 1 cup heavy cream
- 1½ cups shredded Mexican-blend cheese
Pasta
- 12 ounces penne pasta, cooked
Instructions
- Season the Chicken: Generously season the boneless and skinless chicken breasts with salt, black pepper, and the fajita seasoning packet to ensure the flavors are well distributed.
- Prepare Slow Cooker Base: Add the sliced red and green bell peppers along with the sliced onion to the bottom of the slow cooker, creating a flavorful bed for the chicken to cook on.
- Add Chicken: Place the seasoned chicken breasts right on top of the layered peppers and onions in the slow cooker.
- Add Liquids and Cook: Pour the chicken broth over the ingredients, cover the slow cooker, and cook on LOW for 4 to 5 hours. This will allow the chicken to become tender and soak up all the fajita flavors.
- Shred Chicken and Mix Cream: Once cooked, shred the chicken right in the slow cooker using two forks. Stir in the heavy cream to add richness and create a creamy fajita sauce.
- Add Pasta and Cheese: Stir in the cooked penne pasta and shredded Mexican-blend cheese. Mix thoroughly until the cheese melts and everything is well coated in the creamy, fajita-inspired sauce.
Notes
- For a lighter option, substitute heavy cream with half-and-half or whole milk, but the sauce will be less rich.
- If you prefer fewer vegetables, you can reduce the amount of peppers or onion according to your taste.
- Use freshly cooked pasta for best results as it absorbs the sauce better.
- Feel free to add extra fajita seasoning or hot sauce if you enjoy a spicier dish.
- This recipe can be doubled to serve a larger crowd but adjust slow cooker size accordingly.
