Ingredients You’ll Need
- 1½ pounds boneless & skinless chicken breasts: Tender and easy to shred, chicken breasts are the star of this dish. For flavor, consider using thighs if you like a richer taste.
- 1 teaspoon salt: Essential for enhancing all the flavors in your dish. Feel free to adjust based on your dietary needs.
- ½ teaspoon black pepper: A simple spice that adds a touch of warmth without overwhelming the dish.
- 1 1-ounce fajita seasoning packet: This blend gives your dish that classic Tex-Mex flavor. You can create your own mix to suit your taste if you prefer homemade seasoning.
- 1 red bell pepper sliced: Adds sweetness and color. Green bell peppers work just as well if you prefer.
- 1 green bell pepper sliced: Brings a lovely crunch and bright color to your pasta.
- 1 small onion sliced: Adds depth and sweetness. Yellow or white onions are fantastic substitutes.
- ½ cup chicken broth: Keeps everything moist and infuses a rich flavor. Vegetable broth can be used for a vegetarian twist.
- 1 10-ounce can tomatoes with green chiles, drained: Introduces a zesty kick that enhances the fajita theme. Fire-roasted tomatoes offer an extra layer of flavor.
- 3 cloves garlic chopped: Fresh garlic lends an aromatic punch. Use garlic powder in a pinch, but fresh is best!
- 1 cup heavy cream: For that creamy finish that makes every bite indulgent. Light cream works well if you want to reduce richness.
- 12 ounces penne pasta cooked: Penne holds onto the sauce beautifully. Any short pasta works, but avoid long pasta types as they won’t capture the sauce as effectively.
- 1½ cups shredded Mexican-blend cheese: This flavorful cheese mix melts seamlessly into the dish. Feel free to use cheddar or Monterey Jack as alternatives.
How to Make Crockpot Chicken Fajita Pasta

- Season the Chicken: Generously sprinkle 1 teaspoon of salt, ½ teaspoon of black pepper, and the entire 1-ounce fajita seasoning packet over the chicken breasts, ensuring they’re evenly coated.
- Prepare the Vegetables: Place 1 sliced red bell pepper, 1 sliced green bell pepper, and 1 small sliced onion at the bottom of the slow cooker.
- Layer the Chicken: Finally, set the seasoned chicken breasts right on top of the pepper and onion mixture.
- Add the Broth and Cook: Pour in ½ cup of chicken broth, cover the slow cooker, and set to LOW for 4–5 hours. The chicken should be perfectly tender when done.
- Shred the Chicken: Once cooked, shred the chicken directly in the slow cooker using two forks, mixing it into the vegetables.
- Stir in the Cream: Add 1 cup of heavy cream and gently stir until it’s well incorporated into the mixture.
- Combine the Pasta and Cheese: Add in 12 ounces of cooked penne pasta and 1½ cups of shredded Mexican-blend cheese, stirring steadily until everything is melted together and coated in that creamy fajita-style sauce.
Storing & Reheating
Store any leftovers in an airtight container in the fridge for up to 3-4 days. For longer storage, this dish freezes beautifully; just transfer it to a freezer-safe container and store for up to 3 months. To reheat, simply warm it on the stovetop over low heat until it’s heated through, adding a splash of chicken broth to maintain that creamy consistency.
Chef’s Helpful Tips
- Keep an eye on the chicken: Cooking it for too long may dry it out, so check it around the 4-hour mark if you’re unsure.
- Customize your pasta: Feel free to use whole wheat or gluten-free pasta for a healthier twist.
- Make it extra creamy: If you love creaminess, add an additional half cup of heavy cream.
- Adjust the spice level: If you prefer milder flavors, reduce the amount of fajita seasoning or use a mild cheese.
- Enhance with toppings: Top your dish with fresh cilantro, avocado slices, or a squeeze of lime for a refreshing lift.
Crockpot Chicken Fajita Pasta is a fantastic way to bring bold flavors and comfort to your table with minimal effort. The combination of tender chicken, colorful peppers, and delightful creaminess beckons you to enjoy each bite. Don’t be afraid to play with the ingredients to suit your family’s taste.

Recipe FAQs
Can I use frozen chicken in this recipe?
Absolutely! You can use frozen boneless, skinless chicken breasts, but the cooking time may extend by an hour or so. Just make sure to check for doneness before shredding to ensure it’s cooked through.
What can I use instead of heavy cream?
If you’re looking for a lighter option, you can substitute with half-and-half or even Greek yogurt for a tangy twist. However, keep in mind that the texture will differ slightly.

Yes! You can prep everything in advance—season the chicken and slice the veggies—then store them in the fridge. When you’re ready to cook, just pop everything into the slow cooker and let it do its magic.
How do I spice it up further?
To up the heat, consider adding sliced jalapeños or a dash of cayenne pepper to the chicken before cooking. You can also swap the tomatoes with green chiles for a spicier version.
