Garlic potato gratin FAQ:

What is the best way to store leftover garlic potato gratin?

Leftover garlic potato gratin can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, place it in the oven at 350°F (175°C) until warmed through.

How do I know when the potatoes are done in the gratin?

The potatoes are done when they are tender enough to pierce easily with a fork and the top is golden brown, typically after about 60-65 minutes of baking.

Can I substitute the heavy whipping cream?

Yes, you can substitute heavy whipping cream with half-and-half or a plant-based cream for a lighter option, but the texture and richness may vary.

What size baking dish is recommended for this recipe?

A 9x13 inch baking dish is recommended for this recipe to ensure even cooking and layering of the potatoes.

How can I prevent the potatoes from browning before baking?

To prevent the sliced potatoes from browning, you can soak them in cold water for about 30 minutes before assembling the gratin.

Tips:

- Use a mandoline slicer to ensure evenly thin potato slices for an even cook and a professional look.

- Infuse the cream with garlic by gently heating the cream and garlic together before layering it with the potatoes. This helps the garlic flavor to distribute more evenly.

- Cover the dish with foil for the first part of baking to allow the potatoes to cook through without browning too quickly. Remove the foil towards the end to achieve a golden, crispy top.

- Season each layer of potatoes with a pinch of salt and pepper to ensure the dish is fully flavored.

- Allow the gratin to rest for a few minutes after baking before serving. This helps it set slightly and makes it easier to cut into neat portions.
