It transforms what could be a labor-intensive baked dish into a no-fuss, weeknight comfort meal with minimal prep and maximum flavor. Just layer, cook low and slow, and enjoy the delicious payoff hours later.

This comforting dish is especially popular in cold-weather regions like the USA 🇺🇸, Canada 🇨🇦, UK 🇬🇧, Ireland 🇮🇪, and Australia 🇦🇺, where warm casseroles are mainstays at family dinners and holiday spreads. It’s also great for meal prep, potlucks, or feeding a crowd on a budget.

🥛 Step 3: Add Cream & Cook

1. Pour 1 cup heavy cream (or evaporated milk) evenly over the top.
2. Cover and cook on:
   • LOW for 6–7 hours
   • or HIGH for 3–4 hours, until potatoes are fork-tender
