- Step 3: Add the thinly sliced potatoes to the cream mixture and toss until they are fully coated.
- Step 4: Grease a baking dish, then layer the coated potatoes evenly inside. Pour any remaining cream mixture over the top.
- Step 5: Sprinkle the grated cheese evenly over the potato layers.
- Step 6: Cover the dish with foil and bake for 45 minutes.

Tips & Variations
- For extra flavor, add chopped fresh herbs like thyme or rosemary to the cream mixture before baking.
- Use a sharp cheese such as aged cheddar or Gruyère for a richer taste.
- Try mixing in caramelized onions for a deeper onion flavor and added texture.
- If you prefer a lighter version, swap half the cream with milk, but keep the cream to maintain richness.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven at 160°C (320°F) until warmed through to preserve the creamy texture and prevent sogginess.

FAQs
Can I prepare this potato bake in advance?
Yes, you can assemble the dish a few hours ahead of time and keep it covered in the refrigerator. Bake it just before serving, adding a few extra minutes to the baking time if chilled.
What type of potatoes work best for this recipe?
Waxy or all-purpose potatoes are ideal since they hold their shape well during baking. Avoid starchy varieties like Russets, as they can become too soft.
