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.


Summary:
This Crockpot Fajita Pasta Casserole is the ultimate low-effort, high-reward dinner. It’s smoky, creamy, cheesy, and loaded with fajita flavor—without the fuss of standing at the stove. Whether it’s a busy weeknight or you’re feeding a hungry crowd, this set-it-and-forget-it pasta is pure comfort in a bowl.
