FAQs
Can I use cooked rice instead of uncooked rice in this recipe?
This recipe requires uncooked rice to bake correctly with the broth and absorb flavors. Using cooked rice will result in a mushy texture and is not recommended.
Is it possible to make this casserole dairy-free?
Yes, you can substitute the tzatziki sauce and feta cheese with dairy-free alternatives or omit the cheese entirely. Using a coconut or cashew-based tzatziki substitute works well.
