Tips & Variations
- Use chicken thighs for a juicier, more flavorful result.
- Substitute poblano peppers with bell peppers if you prefer less heat.
- For a vegetarian version, replace chicken with mushrooms or tofu and use vegetable broth instead of water.
- Add a squeeze of lemon juice at the end for a fresh, tangy touch.
- If you like it spicier, increase the Cajun seasoning or add extra chili flakes to taste.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a microwave or on the stove over low heat, adding a splash of milk if the sauce has thickened too much.

FAQs
Can I use a different type of pasta?
Yes, short cut pasta like penne or rigatoni works best to hold the sauce, but you can use any pasta shape you have on hand. Just adjust the cooking time accordingly.
Is this recipe freezer-friendly?
It can be frozen, but creamy sauces sometimes change texture after freezing. For best results, freeze the cooked chicken separately and prepare the pasta fresh when ready to eat.
