Crispy Oven Roast Potatoes
Crispy Oven Roast Potatoes are a simple, high-impact side with golden, crunchy edges and fluffy centers. This easy oven method uses a short parboil and a high-temperature roast so the potatoes come out reliably crisp and ready to complement any main dish.
About This Recipe
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.
Ingredients for Crispy Oven Roast Potatoes
- 2 1/2 lb Russet or Yukon Gold potatoes
- 1 tbsp Kosher salt
- 2 tbsp Extra-virgin olive oil
- 1 1/2 tbsp Cornstarch
- 1 tsp Garlic powder
- 1 tbsp Fresh rosemary, finely chopped
- 1/2 tsp Freshly ground black pepper
- 2 tbsp Fresh parsley, chopped (for garnish)
How to Make Crispy Oven Roast Potatoes
Step 1: 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 1/2 lbRusset or Yukon Gold potatoes
Step 2: 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
Step 3: 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 1/2 tbspCornstarch
- 1 tspGarlic powder
- 1 tbspFresh rosemary, finely chopped
- 1/2 tspFreshly ground black pepper
Step 4: 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.Step 5: 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

Crispy Oven Roast Potatoes Tips
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.
Crispy Oven Roast Potatoes Variations and 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.
How to Store and Make Crispy Oven Roast Potatoes 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 Crispy Oven Roast Potatoes
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.
Crispy Oven Roast Potatoes FAQs
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.
