Combine the wine, olive oil and crushed garlic and stir well. Add chicken broth cube, dissolved in 1/5 cup (60 ml) warm water. Pour it over the potatoes. Cover the form with aluminum foil or a lid.
Bake in a preheated oven at 374°F (190 °C) for approximately 45 minutes, then remove the lid or foil and bake for another 45 minutes, until the potatoes turn golden brown.
