⭐ Unsalted Butter (Best Nut-Free Option)
1:1 by volume (e.g., 1/4 cup butter per 1/4 cup coconut oil)Unsalted butter is an excellent substitute because it shares a similar fat content and melting behavior with coconut oil, which is essential for the texture of both the crust and filling in chicken pot pie. The water content in butter (about 15-20%) can slightly affect flakiness but generally enhances flavor.
For best results, use cold butter and cut it into the flour quickly to maintain flakiness. Avoid overworking the dough to prevent toughness. In the filling, butter adds richness and helps meld flavors.
Compared to coconut oil, butter imparts a more traditional savory flavor and slightly less crispness in the crust, but overall it yields a highly desirable texture and taste balance.
