Why This is the Only Roast Potato Recipe You’ll Ever Need
What makes this recipe for crispy roast potatoes so special? It’s all about the technique. We focus on three critical stages: selecting the right potato, parboiling correctly, and roasting at high heat with the right fat. Many recipes might get one or two of these right, but mastering all three is the secret to potato nirvana.
We’re not just giving you steps; we’re explaining the ‘why’ behind them. Understanding why you need a floury potato or why fluffing them up post-boil is non-negotiable will make you a better cook. This is the recipe that will make you famous among your family and friends.
Choosing the Right Potato for Maximum Crispiness
The first step to achieving crispy roast potatoes is selecting the proper variety. You need a “floury” or starchy potato. These potatoes have a lower water content and a fluffy texture that breaks down perfectly during cooking.
- Top Tier Choices: Maris Piper is the undisputed king of roasting potatoes in the UK. In the US, look for Russet or Idaho potatoes. King Edward is another excellent option.
- Potatoes to Avoid: Waxy potatoes like Red Bliss or new potatoes hold their shape too well. They are fantastic for potato salads but won’t give you that desirable fluffy interior and crispy exterior.
The Science of the Perfect Roast Potato
The magic of this recipe lies in a few key scientific principles. First, we parboil the potatoes in slightly alkaline water by adding a pinch of baking soda. This helps break down the potato’s exterior pectin, creating a wonderfully rough and starchy surface area.
After boiling, we shake the potatoes vigorously. This “fluffing” action creates a multitude of micro-cracks and a starchy slurry on the surface. When this starchy layer hits the hot fat in the oven, it fries into an irresistibly crunchy crust that is impossible to achieve otherwise.
Ingredients You’ll Need
- Potatoes: 2 lbs (about 900g) of floury potatoes, like Maris Piper or Russet.
- Fat: 1/2 cup of high-quality fat. Duck fat or goose fat provides the best flavor, but beef dripping or a high smoke point vegetable oil also work wonderfully.
- Salt: Coarse sea salt, for seasoning.
- Optional Flavorings: A few cloves of garlic (smashed) and some fresh rosemary or thyme sprigs to infuse the fat with flavor.
- Baking Soda: A small pinch for the boiling water.
How to Make Crispy Roast Potatoes (Step-by-Step)
Follow these steps meticulously for guaranteed results. The process is simple, but each stage is crucial for building that perfect texture.
Step 1: Preheat and Prepare
Place a sturdy roasting tin in the oven and preheat it to 400°F (200°C). Add your chosen fat to the tin and let it get screaming hot in the oven. This is a critical step; the potatoes must sizzle the moment they hit the pan.
Step 2: Peel and Parboil
Peel the potatoes and chop them into evenly sized pieces, about 2 inches in size. Place them in a large pot, cover with cold water, add a generous amount of salt and a small pinch of baking soda. Bring to a boil and cook for about 10-12 minutes, until the edges are soft but the potato is not falling apart.
Step 3: Drain and Fluff
Drain the potatoes thoroughly in a colander. Let them sit and steam dry for a few minutes. This removes excess moisture, which is the enemy of crispiness. Then, give the colander a good shake to rough up the edges of the potatoes. This is where you create the texture that will become the crispy crust.
Step 4: Roast to Golden Perfection
Carefully remove the hot roasting tin from the oven. Gently place the fluffed potatoes into the hot fat, one by one. They should sizzle immediately. Baste them with the fat, ensuring each potato is well-coated. Roast for 45-60 minutes, turning them every 20 minutes, until they are deeply golden, audibly crispy, and utterly irresistible. If you’re using garlic and herbs, add them in the last 10 minutes of cooking to prevent them from burning. Finish with a final sprinkle of coarse sea salt before serving.
What to Serve With Your Roast Potatoes
These crispy roast potatoes are the ultimate side dish for a variety of mains. They are a classic pairing for a Sunday roast, but their versatility doesn’t stop there. Try them alongside a comforting French Chicken Casserole or as a hearty side to this amazing Pioneer Woman Potato Soup. They also pair beautifully with steak, pork chops, or even a rich Hamburger Supreme Casserole.
Storing and Reheating
While crispy roast potatoes are best enjoyed fresh from the oven, you can store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat and bring back some of the crispiness, place them on a baking sheet in an oven preheated to 400°F (200°C) for 10-15 minutes, or until hot and re-crisped.
Frequently Asked Questions About Crispy Roast Potatoes
You can! You can parboil and fluff the potatoes a day in advance. Let them cool completely, then store them in the fridge. When ready, just roast them in hot fat as directed in the recipe. This can be a great time-saver for big meals.
For the absolute best results, yes. Parboiling cooks the potato partially and, more importantly, allows you to rough up the exterior. This creates a starchy paste that fries in the hot fat, creating an ultra-crispy crust that you can’t get otherwise.
The best potatoes for roasting are starchy, floury varieties. In the UK, Maris Piper is the top choice. In the US, Russet or Idaho potatoes work perfectly. They have a low moisture content which results in a fluffier interior and crispier crust.
For the best flavor, animal fats like duck fat, goose fat, or beef dripping are superior. They have a high smoke point and impart a rich, savory flavor. For a vegetarian option, use a high smoke point vegetable oil, rapeseed oil, or sunflower oil.
The most common reasons are using the wrong type of potato (too waxy), not drying them enough after boiling, not getting the fat hot enough before adding the potatoes, or overcrowding the roasting tin, which causes them to steam instead of roast.
