Method
Preheat the oven to 220°C (425°F) with the rack positioned in the center.
Place scrubbed Yukon Gold potatoes on a cutting board and cut them into uniform 3 to 4 cm chunks using a chef's knife.
Transfer the potato chunks to a large saucepan, cover with cold water by 2 to 3 cm, and stir in the fine sea salt.
Place the saucepan over high heat and bring the water to a rolling boil.
Reduce the heat to medium and simmer the potatoes gently for 15 minutes until tender.
Pour the potatoes into a colander to drain away all cooking water thoroughly.
Return the drained potatoes to the warm, empty saucepan and shake the pot vigorously for 10 seconds to rough up the starchy outer layer.
Place a 30 cm cast-iron skillet over medium-high heat, add the olive oil and the first 30 grams of unsalted butter, and heat until the butter melts and foams.
Arrange the potatoes in the hot cast-iron skillet cut-side down in a single layer and sear undisturbed for 5 minutes.
Using an oven mitt, transfer the cast-iron skillet into the oven preheated to 220°C (425°F) and bake for 20 minutes.
Carefully remove the skillet using an oven mitt, scatter the minced garlic and the remaining 30 grams of butter over the potatoes, and toss gently with a metal spatula.
Return the skillet to the oven and roast at 220°C (425°F) for an additional 5 minutes until the garlic is fragrant and light golden.
Sprinkle flaky sea salt, freshly cracked black pepper, and finely chopped flat-leaf parsley over the sizzling potatoes and serve immediately.
Chef's Notes
- Scuffing the parboiled potatoes inside the dry warm pot creates a micro-slurry of gelatinized starch that dehydrates into a distinct, crackling crust during roasting.
- Yukon Gold potatoes strike an optimal balance between high starch and waxy moisture, yielding a creamy interior that stays intact while developing high-heat surface color.
- Pairing unsalted butter with olive oil provides the rich flavor and Maillard caramelization of milk solids while elevating the smoke point to prevent premature burning.
- Minced garlic burns rapidly at 220°C (425°F); withholding it until the final 5 minutes captures sweet toasted allium aromas without any acrid bitterness.
Storage
Refrigerator: 4 days — Cool completely within two hours of cooking and store sealed in an airtight container.
Freezer: 1 month — Freeze in a single layer on a lined baking tray before transferring to an airtight freezer bag.
Reheating: Reheat in a preheated oven at 200°C (400°F) for 10 to 12 minutes until sizzling and the internal temperature reaches at least 74°C (165°F) throughout.
Troubleshooting
Potatoes turn soft and soggy instead of crisp
Cause: Excessive moisture remained on the potato surface after boiling, or the skillet was overcrowded
Fix: Raise oven temperature to 235°C (455°F) and roast for an extra 6 to 8 minutes to evaporate moisture and crisp the crust
Prevention: Ensure potatoes steam-dry in the warm pan after draining and arrange them in a single, uncrowded layer
Garlic tastes bitter and appears blackened
Cause: Garlic was added too early during the high-heat searing or long roasting phase
Fix: Cannot be fixed if burnt into the crust; carefully brush away charred garlic flakes and toss with an extra tablespoon of melted butter
Prevention: Introduce the minced garlic strictly during the final 5 minutes of roasting as directed
Potatoes break into mush during skillet browning
Cause: Potatoes were overcooked during the initial simmering stage
Fix: Do not stir repeatedly; let them roast undisturbed in the oven so the broken pieces form crispy potato bites
Prevention: Simmer only until knife-tender rather than completely soft, checking doneness at the 12-minute mark
Cultural Context
Skillet-crisped potatoes are a cornerstone of American comfort cuisine, rooted in early hearth-cooking and cast-iron pioneer traditions. Across Southern home kitchens and Midwest diners, par-boiling starchy root vegetables before finishing them in animal fat or butter became the hallmark method for creating a breakfast hash or dinner side with a glass-like exterior crust and pillowy center.
