- Sprinkle with 1/4 teaspoon dill weed and one-third of the Gruyere cheese.
- Repeat the layering with remaining potatoes, seasoning, dill, and cheese.

- Pour the mixture over the layered potatoes.
- Bake until the potatoes are tender and the top is crusty and brown, about 30 minutes.
Tips & Substitutions
For a richer flavor, consider adding minced garlic or onion between the layers of potatoes. If Gruyere cheese is unavailable, Emmental or a sharp cheddar can be great substitutes. To enhance the dish's herbiness, fresh dill can be used instead of dried. Remember to slice the potatoes evenly to ensure they cook uniformly.
Serving Suggestions
Serve the potato gratin as a hearty side dish alongside roasted meats or a green salad for a balanced meal. It pairs beautifully with Chicken Salad, Cuban Style for a refreshing contrast. For an elegant touch, garnish with fresh chives or parsley before serving.
Storage & Reheating
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the gratin in a preheated oven at 350°F (175°C) for about 15-20 minutes until heated through. Cover with foil if the top browns too quickly during reheating.

Frequently Asked Questions
Can I prepare this dish ahead of time?
Yes, you can assemble the gratin a day in advance. Cover it tightly with plastic wrap and refrigerate. When ready to bake, remove the wrap and allow it to come to room temperature before placing it in the oven.
What can I use instead of chicken broth?
If you need a substitute for chicken broth, vegetable broth or even a homemade Rich Chicken Stock can work well. For a lighter flavor, you could use water mixed with a bit of salt and a splash of vinegar to enhance the taste.
How do I know when the gratin is done?
The gratin is done when the top is golden brown and crusty, and a knife or fork can easily pierce the potatoes, indicating they are tender. If the top browns too quickly, cover it loosely with foil to prevent burning while the potatoes cook through.
