Potato slices roasted with onion, thyme, and sea salt give a familiar side dish a new look. The potatoes are sliced as thinly as potato chips and packed upright in a greased baking dish, with pieces of onion tucked between them. Everything is drizzled with a mixture of melted butter and olive oil and baked at 200 °C (400 °F).

Sprinkle salt and crushed chili peppers over the bottom of the dish, and add fresh thyme on top. These potatoes pair well with meat, and vegetables make a good accompaniment.

Instructions

Tip: tap a step to mark it as done.

Preheat the oven to 200 °C (400 °F) and mix the butter and olive oil in a small bowl. Peel the potatoes, or leave the skins on if you prefer, and slice them as thinly as potato chips.
Grease a baking dish with butter and sprinkle a little salt and crushed chili peppers over the bottom. Arrange the potato slices upright in the dish, packed tightly together.
Cut the onions into smaller slices and tuck them between the potatoes. Drizzle the butter and oil mixture over the potatoes, then season with salt and pepper to taste.
Bake at 200 °C (400 °F) for about 60 minutes. If the potatoes brown too quickly, cover them with aluminum foil and lower the oven temperature.
After 40 minutes of baking, add the thyme to the potatoes and finish baking. Sprinkle the finished potatoes with the cheese and bacon.

Tip: Pick up handfuls of potato slices and stand them in the dish like index cards in a file box to make arranging them quicker. Pack them tightly, as they will soften and settle during baking.
