Season the chicken on all sides with the salt, black pepper, and fajita seasoning. Place the seasoned chicken in the bottom of the slow cooker.

Top the chicken with the sliced red and green bell peppers, sliced onion, chopped garlic, and the drained tomatoes with green chiles. Pour the chicken broth over everything.

Cover and cook on low for 4 to 5 hours, or until the chicken is tender enough to shred easily with two forks.
Shred the chicken directly in the slow cooker, then stir in the heavy cream until well combined.
Add the cooked penne pasta and shredded Mexican-blend cheese.

Stir until the cheese is completely melted and the pasta is evenly coated in the creamy sauce.

Let the pasta rest for 5 to 10 minutes to thicken slightly, then serve warm with your favorite toppings if desired.

Crockpot Chicken Fajita Pasta FAQs

Can I use chicken thighs instead of chicken breasts?
Yes. Boneless, skinless chicken thighs stay juicy and work just as well in this recipe.
Why is the pasta added at the end?
Adding cooked pasta at the end keeps it from becoming soft and overcooked during the long cooking time.
Can I make this recipe spicier?
Absolutely. Add sliced jalapeños, extra fajita seasoning, or your favorite hot sauce for more heat.

Can I add extra ingredients?
Yes. Black beans, corn, or even extra bell peppers make great additions to this hearty meal.
How do I store leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days.
Can I use a different type of pasta?
Yes. Rotini, rigatoni, or other short pasta types work well in place of penne.
