Potatoes with garlic and mustard are baked in an oven bag, known in Slovak as a rukáv, or sleeve. The peeled, quartered potatoes are tossed in a bowl with olive oil, pressed garlic, mustard, salt, and fresh parsley. They are then transferred to the bag and baked at 180–200 °C (350–400 °F) for 30–60 minutes, depending on their size.

Inside the closed bag, the potatoes cook in their own steam and absorb the seasonings. Serve them as a side dish with meat.

Instructions

Tip: tap a step to mark it as done.

Have an oven bag ready in addition to the ingredients. In Slovak, this bag is called a rukáv, meaning sleeve, which gives the recipe its name.
Peel the potatoes thoroughly, rinse them, and cut them into quarters.
Place the potatoes in a bowl. Press the garlic into a smaller bowl, add the mustard, parsley, oil, salt, and any additional seasonings to taste, and mix well. Toss the potatoes with the mixture until thoroughly coated.
Transfer the potatoes to an oven bag, close it securely, and make several small holes in it to let steam escape.
Bake at 180–200 °C (350–400 °F) for 30–60 minutes, depending on the oven temperature and the size of the potatoes. Once the potatoes are nicely baked, remove them from the oven and serve immediately.

Tip: For the last 10 minutes, carefully cut open the top of the bag and finish baking the potatoes uncovered so they turn golden. Keep the bag on the baking sheet from touching the oven walls or the upper heating element.
