Can I prepare stuffed onions ahead of time?
Yes. Assemble the stuffed onions up to 8 hours ahead, cover, and refrigerate. Add 10–15 minutes to baking time when cooking from cold.
How do I know when the onions are tender enough?
Pierce an onion layer with a fork after 35 minutes—it should yield easily. The broth should be mostly absorbed and reduced.
Can I use a different grain instead of rice?
Yes. Bulgur (1 cup, uncooked) or farro work well. Adjust liquid slightly if using a grain with different absorption rates.
What if I can't find small yellow onions?
Use medium onions and peel more layers per onion, or halve the quantity and use fewer, larger stuffed portions.
Is this dish freezer-friendly?
Yes. Cool completely, freeze in an airtight container for up to 3 months. Thaw overnight and reheat covered at 350°F for 25–30 minutes.
