The 3 Non-Negotiable Secrets to Emily's Crispy Roast Potatoes

The success of Emily Blunt's English Roast Potatoes is not due to a secret ingredient, but rather a trio of essential techniques that maximize starch activation, surface area, and heat transfer. Ignore these steps at your peril.

1. The Potato and Prep Choice: Yukon Gold & The Peel

The foundation of a great roast potato is the right spud. Blunt’s recipe specifically calls for large Yukon Gold potatoes.

  • Why Yukon Gold? They are a medium-starch potato, which means they hold their shape better than a high-starch Russet, but still have enough starch to create a fluffy interior.
  • The Peel Rule: The potatoes must be peeled and cut into 1.5-inch to 2-inch chunks. While many recipes keep the skin on, peeling is crucial here. Removing the skin allows the starch to be fully exposed and roughened up, which is key to the next step.
  • The Salty Cold Start: The chunks are placed in a pot of cold water with a generous amount of Kosher salt (about 2 tablespoons). Starting in cold water ensures the potatoes cook evenly from the outside in. The heavy salting seasons the potato all the way to its core during the boiling process.

2. The "Roughening Up" Shake Technique

This is arguably the most critical step and the one that separates a good roast potato from a truly great one. Once the potatoes are parboiled until they are just tender—about 10 to 15 minutes—they are drained and immediately "roughed up."

How to Execute the Shake:

  1. Drain the boiled potatoes completely in a colander.
  2. Return the drained potatoes to the empty pot.
  3. Cover the pot with the lid and, holding the lid on tightly, shake the pot vigorously for about 30 seconds.

The Science: The shaking action creates a starchy, almost mashed-potato-like slurry on the surface of each chunk. This slurry is what will crisp up and harden into the shatteringly crunchy crust during the high-heat roasting phase. The roughened edges increase the surface area exponentially, resulting in more crispy bits.

3. The Pre-Heated Fat Bath

The final secret is ensuring the potatoes hit a scorching hot environment right from the start. This technique ensures the roughened, starchy surface immediately begins to dehydrate and crisp, rather than slowly steaming.

  • The Fat Choice: Blunt’s recipe is flexible, allowing for ½ cup of vegetable oil, or for a richer, more traditional English flavor, bacon fat, duck fat, or goose fat. Using animal fat adds a depth of flavor that vegetable oil cannot match.
  • The Pre-Heat: Preheat your oven to 425°F (220°C). Place the fat of your choice directly onto a sheet pan and put the pan into the oven for at least five minutes, or until the fat is shimmering and nearly smoking.
  • The Roast: Carefully transfer the shaken potatoes to the smoking hot pan, ensuring they are coated in the fat and arranged in a single layer. Roast for 45 minutes to 1 hour, turning the potatoes with tongs every 15 minutes until they are deeply golden brown and crisp.

Full Step-by-Step Recipe: Emily's English Roast Potatoes

This recipe, as shared with Ina Garten, requires minimal ingredients but maximum attention to the three techniques above for true potato perfection.

Ingredients:

  • 3 pounds large Yukon Gold potatoes, peeled and cut into 1½- to 2-inch chunks
  • Kosher salt (for boiling)
  • ½ cup vegetable oil, bacon fat, duck fat, or goose fat
  • 1½ to 2 teaspoons coarse sea salt or fleur de sel (for finishing)
  • Optional: Minced fresh parsley, thyme, or rosemary for garnish

Instructions:

  1. Preheat Oven and Fat: Preheat your oven to 425°F (220°C). Place the ½ cup of fat/oil on a sturdy sheet pan and place the pan in the oven for 5–10 minutes until the fat is shimmering hot or just beginning to smoke.
  2. Boil the Potatoes: Place the peeled, diced potatoes in a large pot. Cover them with cold water and add 2 tablespoons of Kosher salt. Bring the water to a boil, then reduce the heat and simmer for 10–15 minutes, or until the potatoes are tender on the outside and a fork can easily pierce them, but they are not falling apart.
  3. Drain and Shake (The Crispy Secret): Drain the potatoes thoroughly in a colander. Return the drained potatoes to the empty pot. Cover the pot with a lid and shake the pot vigorously for 30 seconds. The edges of the potatoes should look fuzzy and roughed up. This creates the starchy crust.
  4. Roast: Carefully remove the hot sheet pan from the oven and transfer the roughened potatoes to the pan, ensuring they are well-coated in the hot fat and spread in a single layer.
  5. Finish: Roast for 45 minutes to 1 hour, using tongs to turn the potatoes every 15 minutes. Continue roasting until the potatoes are a deep, uniform golden brown and exceptionally crisp on all sides.
  6. Serve: Immediately transfer the roasted potatoes to a serving dish. Sprinkle generously with coarse sea salt (or fleur de sel) and minced fresh herbs, if using. Serve hot.

Topical Authority: Why This Method Works

The genius of Emily Blunt’s recipe lies in its perfect execution of two key scientific principles: Gelatinization and Dehydration.

When the potatoes are parboiled and then vigorously shaken, the starch molecules on the surface absorb the water and rupture, a process called gelatinization. This creates the starchy slurry.

When this starchy, roughened surface is immediately exposed to the high heat of the 425°F oven and the smoking hot fat, the water in the slurry rapidly evaporates—dehydration. This fast dehydration causes the starchy crust to harden and turn into an incredibly crisp, golden shell, while the interior remains soft and creamy from the initial boiling. Using a high-smoke-point fat like vegetable oil, duck fat, or goose fat is essential to prevent burning at the high temperature.

This traditional English technique is a masterclass in texture contrast, guaranteeing that every single potato chunk delivers a satisfying crunch followed by a fluffy, melt-in-your-mouth center. It’s a recipe that has earned its viral fame and is now a celebrated part of modern comfort cooking, thanks to a British actress and a beloved American culinary icon.
