Made this tonight using parsnips, turnip, carrots. Used a mirepoix rather than just plain onions at beginning. Turned out a bit dry, but may have had it on too long. But the vegetables turned out so sweet and delicious. The dumplings required non-standard pantry items (flours) that I didn't have on hand, so I cheated and dredged prepared, bite-sized biscuit dough in flour and they cooked in about 20 minutes.
Highest praise was my kid saying it was 'the best dinner she's had in a while' (we'd eaten out/been away for 4 days prior) and my husband agreeing to eat it again. Total winner dinner.
