This timing works every single year.

🔥 Last-Minute Rescue Timing Tips

✔ Potatoes not browning?

Turn oven to 220–230°C for the final 10 minutes.

✔ Potatoes cooking too slowly because oven is full?

Split onto two trays for better airflow.

❌ Timing Mistakes That Ruin Roasties

❌ Putting potatoes in with the turkey

Temps too low — they won’t crisp.

❌ Opening the oven constantly

Loses heat and adds 10+ minutes.

❌ Starting potatoes too early

They’ll soften before serving.

❌ Forgetting to preheat fat

Cold fat = soggy, pale roasties.
