Crispy Oven Roast Potatoes

Crispy Oven Roast Potatoes are the sort of dependable side that transforms a weeknight plate into something memorable without drama. They marry a pillowy interior—thanks to russet or Yukon Gold—with edges that shatter and sing under your teeth, a contrast achieved by a short parboil followed by a hot oven and a light cornstarch dusting. The garlic powder and rosemary here are understated partners: rosemary’s piney lift and garlic’s savory warmth let the potato flavor stay front and center while giving each bite a familiar, comforting seasoning.

This method is for cooks who want consistent results every time. Parboiling seasons and softens the center, roughing the surfaces creates extra nooks for crisping, and cornstarch gives the crust a professional crunch without frying. It’s flexible enough to play well alongside roast chicken, steak, or a simple weeknight fish, and simple adjustments—fat swaps, herb changes, or finishing touches—let you dial the dish toward holiday, rustic, or modern plates while keeping the same fail-safe technique.

Instructions

Preheat oven and cut potatoes

Preheat the oven to 425°F (220°C) and position a rack in the upper-middle. Peel (optional) and cut the potatoes into even 1 to 1 1/2-inch chunks so they cook uniformly.

For this step

2.5 lbRusset or Yukon Gold potatoes

Parboil the potatoes

Place the cut potatoes in a large pot and add cold water to cover by about an inch; add the kosher salt and bring to a boil. Simmer for 8–10 minutes until the edges are just tender but the centers are still firm, then drain well.

For this step

1 tbspKosher salt

Rough the edges and toss with seasonings

Return the drained potatoes to the hot pot and shake vigorously for 30–60 seconds to rough up the surfaces — this creates more crispy edges. On a large rimmed baking sheet, combine the potatoes with olive oil, cornstarch, garlic powder, rosemary, and black pepper, tossing to coat in a single layer with space between pieces.

For this step

2 tbspExtra-virgin olive oil
1.5 tbspCornstarch
1 tspGarlic powder
1 tbspFresh rosemary, finely chopped
0.5 tspFreshly ground black pepper

Rough the edges and toss with seasonings

Roast until golden and crispy

Spread the potatoes cut-side down (if applicable) and roast in the preheated oven for 25–35 minutes, flipping once halfway through, until deeply golden and crisp on the outside. If needed, switch to broil for 1–2 minutes at the end to intensify browning, watching closely to avoid burning.

Finish and serve

Remove the potatoes from the oven and immediately taste for seasoning, adding a pinch of kosher salt if needed, then sprinkle with chopped parsley. Serve hot alongside your main dish for best texture and flavor.

For this step

2 tbspFresh parsley, chopped (for garnish)

Tips from the kitchen

Cut Even Pieces

Trim the potatoes into uniform 1–1½-inch chunks so they parboil and roast evenly; inconsistent sizes are the most common reason for mixed textures.

Parboil to Tenderness

Simmer until the edges are just tender but the centers still hold shape—usually 8–10 minutes—so the interior finishes fluffy during roasting without falling apart.

Rough Up the Edges

After draining, give the pot a vigorous shake or toss with a fork to create fractured surfaces; those rough bits are where the crispiest crust forms.

Cornstarch for Crunch

Tossing the potatoes with a light dusting of cornstarch before oil seals a dry coating that crisps in the oven—use just enough to coat, not clump.

Use a Hot Sheet

If you have time, preheat the rimmed baking sheet in the oven while parboiling; placing the potatoes on a hot surface jump-starts browning and prevents sticking.

Variations & substitutions

Herby Lemon Finish

Swap some rosemary for chopped thyme and finish with a squeeze of lemon and a teaspoon of lemon zest for a brighter, fresher flavor.

Parmesan-Crusted

Sprinkle 1/3 cup finely grated Parmesan over the potatoes in the last 5 minutes of roasting for a nutty, crisp crust that complements the cornstarch crunch.

Swap the Fat

Use rendered duck fat, bacon fat, or ghee instead of olive oil for a richer, more savory finish—these fats brown beautifully and add depth for hearty mains.

Gluten-Free/Starch Swap

If you don’t have cornstarch, use an equal amount of potato starch or a tablespoon less of all-purpose flour for a similar crisping effect.

Storage & make-ahead

Store leftover potatoes in an airtight container in the refrigerator for up to 3–4 days. To re-crisp, spread on a baking sheet and warm in a 400°F (200°C) oven for 8–12 minutes; avoid microwaving unless you don’t mind softened edges. For make-ahead, parboil and dry the potatoes, then refrigerate on a tray uncovered for a few hours before roasting to dry the surface further for extra crunch.

What to serve with it

These potatoes are a classic partner for roast chicken, pork chops, or a simply grilled steak, and they stand up well to rich sauces like mushroom pan sauce or chimichurri. For vegetables, pair with blistered green beans or a dressed arugula salad to add brightness; serve with a glass of medium-bodied red like Pinot Noir or a crisp pilsner to balance the richness.

Frequently asked questions

Can I skip the parboil step?

Skipping parboil sacrifices the fluffy interior; you can roast from raw but expect longer cooking time and less reliable texture. If short on time, microwave the cut potatoes 4–6 minutes to soften centers before roasting.

Why add salt to the parboil water?

Salting the cooking water seasons the potato from the inside, improving overall flavor without relying solely on surface seasoning after roasting.

How do I avoid soggy potatoes?

Don’t overcrowd the pan, ensure pieces are well dried before oiling, use the hot-sheet trick, and keep space between pieces so steam can escape and edges can brown.

Which potato is best: Russet or Yukon Gold?

Russets yield the fluffiest interior and a slightly crisper exterior, while Yukon Golds are creamier and hold their shape a bit better; both work—choose based on whether you prefer a fluffier or creamier bite.

Can I make these in an air fryer?

Yes—air fry at 400°F (200°C) for about 20–25 minutes, shaking every 6–8 minutes; reduce cornstarch slightly if you notice excess browning.
