Vegetable Shortening (Best Option)
1:1 (1 cup shortening per 1 cup coconut oil)Vegetable shortening is a hydrogenated fat that remains solid at room temperature, similar to coconut oil, which helps replicate the fat’s role in tenderizing the dough and supporting gluten structure. This solid fat contributes to the characteristic dense and chewy texture of bagels by coating flour proteins and controlling moisture.
For best results, ensure the shortening is fully incorporated and chilled if needed to mimic coconut oil’s consistency. Avoid overmixing to prevent excessive gluten development which can toughen the bagel.
Compared to coconut oil, vegetable shortening is neutral in flavor and slightly more processed, but it preserves the essential textural qualities, making it the closest functional substitute in bagel recipes.
