Step-by-step instructions
- Preheat the oven to 180°C (350°F).
- Peel and slice the potatoes into thin rounds.
- In a large mixing bowl, combine the sliced potatoes, diced ham, grated cheese, whole milk, and heavy cream. Season generously with salt and pepper according to your taste.
- Grease a baking dish, then layer the potato mixture evenly, ensuring everything fits snugly.
- Bake in the preheated oven for about 1 hour, or until the potatoes are easily pierced with a fork and the top achieves a lovely golden brown hue.
- Allow the gratin to cool slightly before serving, enhancing the flavors and making it easier to slice.
How to serve Ham and Cheese Potato Gratin
This gratin shines on its own but can be paired brilliantly with a fresh green salad, steamed vegetables, or roasted meats. For a rustic touch, serve it directly from the baking dish with a sprinkle of fresh herbs atop each serving. You can also elevate this dish by offering different mustards or a dollop of sour cream on the side for added creaminess.
Storage and reheating tips
To keep your Ham and Cheese Potato Gratin fresh, store any leftovers in an airtight container in the refrigerator for up to 3 days. For longer storage, it can be frozen for about two months. When reheating, place in the oven at 180°C (350°F) until warmed through. Always ensure food is heated to a safe internal temperature of 75°C (165°F) before consuming.
Pro chef tips
Here are some tips to make your gratin even better:
- Use a mandoline slicer for perfectly uniform potato slices to ensure even cooking.
- If you prefer a crispier top, leave it uncovered during the last 10-15 minutes of baking.
- Experiment with different cheeses for a unique flavor profile; a blend of cheeses can provide depth and richness.

Feeling adventurous? Here are a few variations to consider:
- Add sautéed onions or garlic for extra aroma and flavor.

- Swap the ham for cooked bacon or sautéed mushrooms for a meatless version.
