🔪 Step-by-Step Instructions
Step 1 – Roast the Potatoes

💡 Chef’s Tips
- Check sauce thickness – it should coat the back of a spoon.
- Don’t overbake cod – check at 10 minutes; it cooks quickly.
- Use red or russet potatoes if Yukon golds aren’t available.
- For a lighter version – swap cream for half-and-half.
🧊 Storage & Reheating
