Can I use raw chicken instead of cooked?
Yes. Dice raw chicken into bite-sized pieces and cook in the butter and oil for 5–7 minutes until no longer pink before adding vegetables.
How do I prevent the sauce from being too thick or thin?
The flour creates the roux base; simmer gently to thicken. If too thin, mix 1 tbsp cornstarch with 2 tbsp water and stir in. If too thick, add chicken broth or cream by the tablespoon.
Can I make this ahead or freeze it?
Yes. Store in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop with a splash of broth to restore creaminess. Freezing may separate the sauce; not recommended.
What can I substitute for heavy cream?
Use whole milk mixed with 1 tbsp cornstarch, half-and-half, or Greek yogurt stirred in off heat. Heavy cream delivers the richest result.
Can I double this recipe?
Yes. Double all ingredients and cook in a larger skillet or Dutch oven. Adjust simmering time slightly to ensure even heating.
