About the ingredients
Method
- Preheat oven around 420°F. Set rack mid-height to avoid burning edges.
- Pat potatoes very dry, the drier the crisper skin. Cut thin parallel slits about 1/8 to 1/5 inch apart, stopping just before bottom slice stays connected. It helps to rest on a damp towel for grip.
- Optional: slice a small flat on bottom to prevent rolling, steady slicing.
- Arrange potatoes on rimmed baking sheet. Brush 3 tablespoons olive oil inside slits and whole surface, really get at those cracks.
- Generously sprinkle sea salt and fresh cracked pepper over entire potato, salt seals crust formation.
- Bake 40 to 50 mins until slices visibly open and edges start crisping with golden tips.
- While baking, soften 3 tablespoons butter in small bowl; whisk in garlic powder and whole grain mustard instead of Dijon for a rustic tang.
- Remove potatoes, brush butter mixture thoroughly over and in between slices for flavor and moisture.
- Return to oven for 15-20 mins till layers crisp distinctly and deeper golden tone appears.
- Turn oven off but leave potatoes inside to rest, consolidates texture without drying out. Size dictates final crisp times, bigger need longer after glazing.
- Stuff cheese evenly into slits, use back of spoon to push deeper. Return to warm oven 1-2 minutes, watch so cheese melts but does not burn or dry.
- Top with dollops of sour cream, sprinkle chives, scattered crisp pancetta (or bacon). Optional pinch smoked paprika for extra aroma.
- Serve while still hot so cheese gooey, skins brittle-crisp. Adds texture contrast and smoky richness.
- Leftovers reheat but lose crisp. Best fresh.
- If potatoes resist slicing, chill for 20 minutes before—firmer for precision cuts, helps avoid breaking bottom.
- Alternate toppings like sautéed mushrooms or caramelized onions work too. Finish with drizzle of truffle oil for luxury take.
Cooking tips
Chef's notes
- 💡 Slice thin but stop before bottom slice—keeps layers connected. Use damp towel or chopsticks on sides for steadiness. Yukon golds chosen for creamy inside—russets get crispier but risk dryness. Brush oil deep into the slits, not just surface. Early seasoning with salt after oil seals the crust. Thickness matters—a thick cut means undercooked layers, too thin means breaking. Sharp paring knives give best control.
- 💡 Butter mix with garlic powder and whole grain mustard not Dijon—less sharp, more rustic flavor. Mix softened butter thoroughly, whisk in powders just before glazing so powder doesn’t clump. Brush between layers generously, sealing moisture. Timing is loose here; aim for glossy surface—signals absorption. Let potatoes rest in oven off phase to settle moisture before cheese stuffing; avoids rubbery burn risk.
- 💡 If potatoes resist slicing, chill for 20 minutes first—firmer slices, cleaner cuts. A small flat cut on bottom prevents rolling and slipping during slicing. Bake times vary with potato size and thickness. Use visual cues—edges golden, slices visibly open, hearing crackling sound—better than timer alone. Cheese only last step; melts gooey inside cracks, not stringy. Return to warm oven briefly—1-2 minutes max.
- 💡 Sour cream and pancetta sprinkling adds texture contrast—crunch meets creamy tang. Bacon can substitute pancetta; smoked paprika sprinkle optional but builds aroma layer. Olive oil quantity important—too little skin dries, too much makes soggy. Preferred unsalted butter balances salt added via oil and seasoning. Microwave shortcut speeds baking but loses crisp texture—only if pressed for time.
- 💡 Patience with slicing and brushing oil pays off—rushing kills crisp edges. Crispy skin and creamy center balance needs thin parallel cuts and deep oil brushing. Visual separation between slices and crackling sound are your go signals. Use silicone brush for coverage. Leftovers lose crisp; best fresh. Alternate toppings like sautéed mushrooms or drizzle truffle oil can update flavor profile.
Common questions
How thin should the potato slices be?
Aim for 1/8 to 1/5 inch apart. Close enough to open but not cut all the way through. Stop just before bottom slice holds them together. Use chopsticks or wooden spoons on sides prevent cutting through. Thinner slices crisp better but risk breaking. Thickness impacts cooking time too.
Can I substitute russets for Yukon gold?
Russets crisp more, create crunchier skin, but they dry faster. Yukon gold stay creamier inside; better for softer centers. Butter and oil absorption differ slightly. Either works but watch bake times, russets may need shorter or more careful timing to avoid dryness. Adjust seasoning accordingly.
What if slices don’t fan open during baking?
Could be cut too thick or not stopping at bottom slice. Try chilling potatoes before slicing for firmer cuts. A flat bottom helps steady. Baking at too low temp slows opening. Watch visual cues; if too dense, cook longer after glazing to crisp layers. Avoid cutting fully through—slices fall apart.
How best to store and reheat leftovers?
Refrigerate in airtight container. Crispy texture lost after reheating. Warm gently in oven or toaster oven to revive edges but expect softer skin. Microwave heats faster but makes skin soggy. Leftovers good for next day mash or skillet frying for crisp patches again. Not ideal reheated straight as baked.
