Professional secrets

• Use the convection setting for an even caramelized crust.
• Rotate the sheet halfway through to avoid hot spots.
• Finish with a splash of acid (lemon) to balance the sweet.

Common mistakes to avoid

• Overcrowding the pan, which steams the potatoes instead of crisping them.
• Skipping the oil; the skin won’t develop that golden sheen.
• Leaving wedges too thick; they stay hard in the center.

Substitutions

• Olive oil: Melted butter or coconut oil. Butter adds a richer flavor; coconut oil adds a subtle tropical note.
• Sea salt: Kosher salt. Use the same amount; texture will be slightly coarser.

Variations

• Spicy Version: Add a pinch of cayenne and drizzle a tiny spoonful of sriracha after baking for a gentle heat.
• Mediterranean Style: Sprinkle crumbled feta and chopped olives over the hot wedges before serving.

Storage

Store cooled wedges in an airtight container in the fridge for up to three days.

Make ahead

You can slice and coat the potatoes up to 12 hours ahead; keep them covered in the fridge and bake when ready.

Leftovers

Reheat gently in a skillet over medium heat, adding a splash of water to revive the steam inside.

Serving ideas

• Serve hot directly from the tray with a side of miso soup.
• Pair with a bright cucumber salad dressed in rice vinegar.
• Garnish with a light sprinkle of toasted sesame seeds.
