Ingredients You’ll Need
- 1½ pounds boneless & skinless chicken breasts: Provides lean protein. You can substitute with thighs for a richer flavor.
- 1 teaspoon salt: Enhances overall flavor. Feel free to adjust to taste.
- ½ teaspoon black pepper: Adds subtle heat. Freshly ground pepper gives the best flavor.
- 1 (1 ounce) fajita seasoning packet: Packs in the authentic fajita taste. You can also make your own blend using chili powder, cumin, and paprika.
- 1 red bell pepper, sliced: Offers sweetness and crisp texture. Substitute with any color pepper you prefer!
- 1 green bell pepper, sliced: Adds a nice contrast to the sweetness of the red pepper.
- 1 small onion, sliced: Contributes savory depth. A red onion works well for a touch of sweetness.
- ½ cup chicken broth: Keeps the chicken moist while also enriching the sauce. Use vegetable broth for a vegetarian option.
- 1 (10 ounce) can tomatoes with green chiles, drained: Provides a zesty kick. Fresh diced tomatoes can work too, but you’ll lose some of the heat.
- 3 cloves garlic, chopped: Adds savory flavor and aroma. You can use garlic powder in a pinch but the fresh garlic is best.
- 1 cup heavy cream: Creates the creamy, luscious sauce that brings everything together. Use half-and-half or a dairy-free cream for lighter alternatives.
- 12 ounces penne pasta, cooked: Pasta gives a satisfying texture to the dish. Feel free to use gluten-free pasta or any type you enjoy.
- 1½ cups shredded Mexican-blend cheese: Melts beautifully, enhancing the creaminess. Try a sharp cheddar or pepper jack for an extra kick.
How to Make Slow Cooker Fajita Pasta

- Season the Chicken: Generously sprinkle 1 teaspoon of salt, ½ teaspoon of black pepper, and the fajita seasoning packet over the chicken breasts, ensuring they are well-coated.
- Prepare the Base: Add the sliced red and green bell peppers along with the sliced onion to the bottom of the slow cooker. Their colors will make a lovely base!
- Layer the Chicken: Place the seasoned chicken right on top of the veggies in the slow cooker.
- Add the Liquid: Pour in ½ cup of chicken broth and 1 (10 ounce) can of drained tomatoes with green chiles over the chicken. Cover the slow cooker and set it to cook on low for 4–5 hours, until the chicken is fork-tender.
- Shred the Chicken: After cooking, shred the chicken directly in the slow cooker using two forks. It’s so tender it should fall apart easily.
- Stir in the Cream: Add 1 cup of heavy cream to the shredded chicken, stirring until well mixed.
- Combine the Pasta and Cheese: Finally, fold in 12 ounces of cooked penne pasta and 1½ cups of shredded Mexican-blend cheese, stirring until everything is melted and the pasta is beautifully coated with that creamy, fajita-style sauce.
Storing & Reheating
Leftovers can be stored in an airtight container in the refrigerator for up to 3–4 days. For longer storage, scoop portions into freezer-safe bags, ensuring excess air is removed, and freeze for up to 3 months. To reheat, simply thaw in the fridge overnight and warm on the stovetop over low heat, stirring frequently. If the pasta appears dry, adding a splash of chicken broth or cream can help bring back the creaminess.
Chef’s Helpful Tips
- To avoid dry chicken, make sure you don’t overcook. Check around the 4-hour mark for tenderness.
- For a richer flavor, try adding a squeeze of lime juice just before serving.
- You can adjust the amount of fajita seasoning depending on your spice preference.
- If you want a little crunch, consider garnishing with fresh cilantro or green onions before serving.
- Remember to save leftovers for an easy lunch the next day!
