Frequently Asked Questions
- → How do I ensure the chicken stays juicy?
Sear the chicken over medium-high heat and avoid overcooking. Slicing it into thin strips helps it cook quickly and evenly, keeping the meat tender.
- → Can I use a different type of pasta?
Absolutely. While spaghetti works well, other types like fettuccine or linguine also pair delightfully with the creamy Cajun sauce.
- → Is there a way to make it less spicy?
To reduce the heat, use less Cajun seasoning and skip the red pepper flakes. You can also add extra cream to mellow the flavors.
- → What can I substitute for heavy cream?
Half-and-half or full-fat milk can be used, but the sauce will be slightly less rich and thick. Cream cheese also helps with creamy texture.
- → How can I store leftovers?
Place cooled leftovers in an airtight container in the fridge for up to three days. Reheat gently to preserve the sauce’s creamy texture.
