Ingredients:
- 1 lb boneless, skinless chicken breasts or thighs (cut into strips or leave whole to shred later)
- 1 red bell pepper, sliced
- 1 green bell pepper, sliced
- 1 yellow onion, sliced
- 2 teaspoons chili powder
- 1 teaspoon cumin
- ½ teaspoon smoked paprika
- ½ teaspoon garlic powder
- Salt and pepper, to taste
- 1 (10 oz) can diced tomatoes with green chiles (like Rotel)
- ¾ cup chicken broth
- 4 oz cream cheese
- 10 oz dry penne or rotini pasta (added at the end)
- 1 ½ cups shredded cheddar or Mexican blend cheese (divided)
- Optional: chopped cilantro, green onions, jalapeños, or sour cream for topping
Instructions:
Add to Crockpot:
Place chicken, bell peppers, onions, seasonings, diced tomatoes, and broth in the crockpot. Stir to coat everything evenly.
Cook:
Cover and cook on low for 4–5 hours or high for 2½–3 hours, until the chicken is fully cooked and veggies are tender.
Shred Chicken (if needed):
If you left the chicken whole, shred it in the pot using two forks.
Stir in Cream Cheese & Pasta:
Add the cream cheese and stir until melted and smooth. Then stir in the uncooked pasta and 1 cup of the shredded cheese.
Cook Again:
Cover and cook on high for an additional 20–30 minutes, or until pasta is tender. Stir once or twice during cooking if you can.
Top with Cheese:
Sprinkle the remaining ½ cup cheese over the top, cover, and let it melt for a few more minutes before serving.
Crockpot Fajita Pasta Tips:
- Pasta Watch: Pasta cooks quickly in the slow cooker. Check it around the 20-minute mark to avoid overcooking.
- Customize the protein: Swap chicken for sliced steak, ground turkey, or beans for a vegetarian version.
- Make it spicy: Add jalapeños, chipotle powder, or hot sauce for more heat.
- Make ahead: You can prep everything except the pasta the night before and store it in the fridge until morning.
Notes:
- Serves 6
- Store leftovers in the fridge for up to 4 days
- Reheat with a splash of broth or milk to keep it creamy
- Freezes best before adding the pasta
Make It a Meal (and Then Another One):
Serve with tortilla chips, salsa, or a fresh green salad. Leftovers are great in burritos or even stuffed in bell peppers for a second-day spin.
