Witch in the Kitchen has some great recipes that are easily adaptable and simple to make. The potato gratin takes very little ingedients, prep and equipment making it perfect for a night when you don't want to spend a lot of work on a delicious dinner.
The recipe calls for a medium size gratin dish. I didn't have one, so I improvised with my tart pan. If you do this, make sure you add more water!
So for two people you will need:
1 large piece of garlic
2 large and 1 small potato
salt & pepper
2 teaspoons butter
water or stock
Preheat to 350 F.
Rub the inside of your dish with the garlic. Thinly slice your potatoes using a mandoline so that all the slices are neat and even. Layer, overlapping and then sprinkle with salt & pepper. Continue layering until you have used all the potatoes. Slice the garlic clove and lay across the top.
If you want more flavor, you can add some spices, such as dill, thyme or bay leaf, depending on your tastes, sprinkling across the top.
Add 2-3 dots of buuter and add enough water to make sure the bottom of the dish is completely covered with water or stock. Cook on a low rack for about 45 minutes. Check halfway through, if your oven runs hot you need to a bit more liquid.
In the photo above, I served it with haricots verts and some juicy chops with a glaze of Blood Orange Meyer Lemon Marmalade.
