FAQ: Vietnamese Green Bean Casserole

Is this casserole fully vegetarian? Yes. It uses vegetable broth, soy sauce, mushrooms, and coconut cream for savory depth without meat.

Can canned green beans be used? Yes. If using canned, reduce bake time to 10–12 minutes so they don’t soften too much.

Can this be made ahead? Assemble up to one day in advance. Add crispy shallots right before baking so they stay crunchy.

Does coconut cream make it sweet? No. Coconut cream adds richness and balance without noticeable sweetness.
