Yes, store any leftovers in an airtight container in the refrigerator for up to 3-4 days. Reheat in the oven or microwave before serving.
You can substitute prosciutto with cooked bacon, pancetta, or a vegetarian option like sautéed mushrooms for a similar flavor and texture.
Starchy or waxy potatoes, like Russet or Yukon Gold, are ideal for gratin as they hold their shape and create a creamy texture when baked.
- Precook the leeks and potatoes: For an evenly cooked gratin, consider precooking the leeks and potatoes slightly by sautéing the leeks until tender and parboiling the potatoes before layering them in the baking dish.
- Use a mandolin for even slices: To ensure uniform cooking, use a mandolin to slice the potatoes evenly. This will also help achieve the desired texture for your gratin.
- Layer for best flavor distribution: Layer the ingredients thoughtfully by placing a mix of leeks and prosciutto between the potato slices. This ensures every bite is packed with flavor.
- Check for seasoning: Taste your mixture before adding it to the baking dish. Cheese and prosciutto can be quite salty, so you may not need to add much additional salt.
- Let it rest: Allow the gratin to rest for a few minutes after baking. This helps the dish to set and makes it easier to cut clean portions.
- Customize with other cheeses: Feel free to experiment with different cheeses like Gruyère or Parmesan for an added depth of flavor.
