With mashed potatoes you want to work against the potato’s starch to keep the mash from getting gluey. With a gratin you’re utilizing the starch to make the whole dish gel. This is one of those classic dishes that are more than the sum of its parts. While it uses a good deal of fat (falling into classic potato reputation) I usually combine it with a very acidic green salad, a raw carrot or cabbage slaw and a low fat protein to make a meal that is balanced, filling but not a gut bomb.
- 3 lbs waxy potatoes, Yukon Gold or German Butterball
- 1 C heavy cream

- Heat the oven to 350F

- Layer the potatoes along the bottom of an ovenproof baking dish
- Season liberally with salt and pepper
- Continue layer after layer until all potatoes are used up, seasoning each layer liberally
- Pour the cream over the potatoes
- Top with the grated cheese if using
- Cover the whole lot with tinfoil and bake until potatoes are tender when pierced (about 40 min)
- Uncover and bake additional 10 minutes to brown the top
