Homemade Roast Potatoes

Last Sunday, my kitchen smelled like rosemary and hot fat, the kind of aroma that makes people linger near the oven door. I'd been making these roast potatoes for years, but somehow my cousin's toddler, who usually eats nothing, asked for seconds. That's when I realized the secret isn't some fancy technique but giving the potatoes exactly what they need: time, heat, and a little rough treatment.

I learned the roughening trick from a chef who told me that ragged edges are what catch the fat and turn golden. Before that, I'd carefully slide my potatoes into the pan, wondering why they never quite achieved that restaurant quality. Now I give them a proper shake in the pot, almost like I'm angry at them, and the difference is remarkable.

Ingredients

• Floury potatoes: Maris Piper, Yukon Gold, or Russet work best because they break down slightly on the surface, creating natural crispiness
• Salt for boiling: This seasons the potatoes from the inside out, so every bite is flavorful
• Hot fat: Duck or goose fat gives the best flavor, but vegetable oil works perfectly well
• Sea salt flakes: These provide a final crunch and burst of salinity that table salt can't match
• Fresh herbs: Rosemary or thyme add aromatic notes that complement the earthy potatoes

Instructions

Preheat your pan:

Put your roasting tray in the oven at 220°C while you prep, so the fat sizzles immediately when the potatoes hit it

Parboil the potatoes:

Simmer them for 8 to 10 minutes until the edges start to soften but the centers stay firm

Steam dry:

Drain well and let them sit for 2 minutes, then shake vigorously in the pan until the surfaces look rough and cloudy

Coat with fat:

Pour the hot oil over the potatoes and toss gently until every piece has a glossy sheen

Roast and turn:

Spread in a single layer on the hot tray and roast for 20 minutes, then flip and continue until golden and crispy

My grandmother used to say that good roast potatoes are worth more than the main course. I didn't understand until I hosted Christmas dinner and watched everyone fight over the last one, completely ignoring the roast beef. Now I always make extra, because someone will inevitably sneak a potato from the serving dish while I'm still plating everything else.

Choosing The Right Fat

Vegetable oil produces a clean, neutral crispness that lets the potato flavor shine through. Duck or goose fat adds a rich, savory depth that feels indulgent and restaurant quality. Lard sits somewhere in between, offering porkiness without being overwhelming.

Temperature Timing

I've found that starting at 220°C gives the best initial crunch, then lowering to 200°C prevents burning while the interiors finish cooking. If your oven runs hot, check them at 35 minutes. If it runs cool, they might need the full 50 minutes to achieve that perfect golden color.

Make Ahead Strategy

You can parboil and roughen the potatoes up to 24 hours in advance, then store them covered in the refrigerator. Bring them to room temperature before roasting, or add 5 to 10 minutes to the cooking time. I've even frozen them after the boiling step and roasted straight from frozen with excellent results.

• Don't overcrowd the pan or the potatoes will steam instead of crisp
• A glass baking dish works but metal produces better browning
• Season immediately after roasting while the fat is still hot

Perfect roast potatoes are simple, but they're never boring. These might just become the most requested side dish in your kitchen.

Recipe FAQs

→ What potatoes are best for roasting?

Floury potatoes like Maris Piper, King Edward, or Yukon Gold work best. Their high starch content creates fluffy interiors while developing crispy exteriors when roasted.

→ Why do you parboil potatoes before roasting?

Parboiling softens the interior while roughening the edges. This creates maximum surface area for crisping and ensures fluffy centers that aren't undercooked.

→ Can I make these ahead of time?

Yes. Parboil and roughen the potatoes, then freeze on a tray. Once solid, store in bags. Roast from frozen, adding 5-10 minutes to cooking time.

→ What fat gives the crispiest results?

Duck or goose fat produces the crispiest, most flavorful potatoes. Vegetable oil is a excellent vegetarian alternative that still yields great results.

→ Why shake the potatoes after draining?

Shifting the potatoes in the pan roughens their surfaces. This creates extra crispy edges and helps the fat coat more evenly for superior crunch.

→ What temperature should I roast potatoes at?

220°C (430°F) creates the crispiest results. Starting with a preheated tray and hot fat ensures immediate sizzling and golden browning.
