Ingredients You’ll Need
- 1½ pounds boneless & skinless chicken breasts: This lean meat becomes tender and flavorful after slow cooking. If you need a substitute, you could use bone-in chicken thighs for extra flavor, though cooking time might vary.
- 1 teaspoon salt: Essential for enhancing the overall flavor. Adjust according to taste.
- ½ teaspoon black pepper: Adds a little kick without overwhelming the dish.
- 1 (1 ounce) fajita seasoning packet: This blend of spices gives that signature Tex-Mex flavor. You can make your own mix if preferred.
- 1 red bell pepper, sliced: Not only does it add sweetness, but its vibrant color makes the dish more appealing.
- 1 green bell pepper, sliced: The slight bitterness of the green pepper balances the sweetness of the red.
- 1 small onion, sliced: Onions bring depth and sweetness, caramelizing beautifully during cooking.
- ½ cup chicken broth: Helps keep the chicken moist and packs in flavor. Low-sodium broth is a good option.
- 1 (10 ounce) can tomatoes with green chiles, drained: These lend a nice tang and a hint of spice. If you prefer fresh, use diced tomatoes and a few chopped jalapeños.
- 3 cloves garlic, chopped: Garlic infuses a lovely aroma and richness—always a must!
- 1 cup heavy cream: This creates the creamy texture that binds it all together. For a lighter version, substitute with half-and-half or a dairy-free alternative.
- 12 ounces penne pasta, cooked: The perfect vessel for soaking up all that delicious sauce. Opt for whole wheat or gluten-free pasta for a healthier twist.
- 1½ cups shredded Mexican-blend cheese: Melts beautifully, adding richness; feel free to use cheddar or pepper jack for extra flavor.
How to Make Slow Cooker Fajita Pasta

- Season the Chicken: Generously sprinkle 1 teaspoon salt, ½ teaspoon black pepper, and the seasoning from the fajita seasoning packet over the chicken breasts. Make sure they’re evenly coated; this will bring out the best flavors.
- Arrange the Vegetables: Place the sliced red and green bell peppers and the onion at the bottom of the slow cooker. This creates a bed for the chicken to rest on.
- Add the Chicken: Place the seasoned chicken right on top of the vegetables. It will soak up their flavors as it cooks.
- Pour in the Broth: Carefully add ½ cup chicken broth around the chicken, ensuring it doesn’t wash away the seasoning. Cover and set your slow cooker to LOW for 4–5 hours.
- Shred the Chicken: Once done, use two forks to shred the chicken right in the cooker. It’s tender enough that it should fall apart easily.
- Stir in the Cream: Pour in 1 cup of heavy cream and stir gently to incorporate it with the shredded chicken and veggies. Watch as the sauce transforms into a creamy delight!
- Add Pasta and Cheese: Finally, mix in your cooked 12 ounces of penne pasta, followed by 1½ cups of shredded Mexican-blend cheese, stirring until everything is well combined and the cheese is melted. This creamy, cheesy blend is absolutely irresistible!
Storing & Reheating
Store any leftovers in an airtight container in the refrigerator for up to 4 days. If you want to keep it longer, it’s freezer-friendly for up to 3 months. Just be sure to cool it completely before transferring to freezer-safe bags or containers. When you’re ready to enjoy again, reheat in the microwave or on the stovetop over low heat, stirring occasionally. Note that the pasta may absorb more sauce during storage, so feel free to add a splash of broth or cream while reheating to refresh its creamy consistency.
Chef’s Helpful Tips
- Avoid overcooking the chicken; you want it tender but not mushy. Timing may vary slightly based on your slow cooker.
- If your pasta is made ahead, consider cooking it slightly less than al dente, so it doesn’t get mushy when mixed with the sauce later on.
- For extra flavor, sauté your garlic and onions before adding to the slow cooker; this helps develop a deeper taste.
- Feel free to add other veggies like mushrooms or zucchini for an extra boost. They’ll absorb the flavors of the dish beautifully.
- This recipe is great for meal prep; just allow it to cool before dividing into individual servings for lunches or easy dinners during the week.
Certainly, a dish like this Slow Cooker Fajita Pasta is incredibly satisfying. It combines simplicity and robust flavors that make cooking feel effortless while delivering a hearty meal. Don’t shy away from experimenting with different spices or adding your favorite seasonal veggies—cooking is all about personalizing each dish to your liking.
