Perfect Roasties: The Cornerstone of a Proper Sunday Lunch

My grandmother, bless her heart, wasn’t the most adventurous cook. But her Sunday roasts? Unbeatable. The centerpiece, of course, was always the meat – usually lamb or beef – but the real star, in my humble opinion, were the roast potatoes. I can still picture the steaming bowlful, glistening with fat, their crisp, golden surfaces giving way to fluffy, almost creamy insides. No matter how full I was, I always managed to sneak a few extra. Those memories, that taste – it’s pure comfort on a plate.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 1 hour 30 minutes
• Total Time: 1 hour 45 minutes
• Servings: 4-6
• Yield: Generous portion for 4-6
• Dietary Type: Vegetarian (can be Vegan if using vegetable oil)

Ingredients

• 20 medium sized potatoes, peeled and cut into even sized pieces
• Goose fat or duck fat, melted to coat roasting pan
• 1 tablespoon plain flour
• Sea salt

Equipment Needed

• Large saucepan
• Colander
• Large roasting pan (enamel, metal, or Pyrex)
• Oven

Instructions

1. Begin by par-boiling the potatoes. Peel them and cut them into roughly equal sizes – halve smaller potatoes, quarter larger ones to ensure even cooking.
2. Place the prepared potatoes in a large saucepan filled with cold, salted water. The water should completely cover the potatoes.
3. Bring the water to a boil over high heat. Once boiling, reduce the heat slightly and continue to boil for approximately 5 to 6 minutes. This crucial step softens the potatoes for roasting while keeping them intact.
4. Drain the potatoes thoroughly in a colander, reserving some of the cooking water for gravy, if desired.
5. Return the drained potatoes to the empty saucepan. Allow some of the steam to evaporate, then securely place the lid back on the pan.
6. Holding the lid tightly, shake the pan vigorously for about 30 seconds. This roughs up the edges of the potatoes, creating a larger surface area for ultimate crispiness. You’re aiming for a slightly mashed, fluffy exterior.
7. Sprinkle 1 tablespoon of plain flour over the potatoes in the pan. Replace the lid and shake again, ensuring that the flour evenly coats all the potatoes. The flour acts as a bonding agent, helping the fat to adhere and crisp up during roasting.
8. Remove the lid from the pan and allow the potatoes to air-dry slightly while you prepare the fat. This step is important for achieving extra-crisp roasties.
9. Preheat your oven to 200°C/400°F.
10. In a large roasting pan, add enough goose fat or duck fat to generously coat the bottom. The potatoes should not be swimming in fat; aim for a depth of less than 1/2 cm or 1/4 inch. For a vegan option, use a high-quality vegetable oil with a high smoke point.
11. Place the roasting pan with the fat into the preheated oven for 10 minutes, allowing the fat to get smoking hot. This is essential for that initial sizzle and perfect browning.
12. Carefully remove the roasting pan from the oven. Using tongs or a slotted spoon, gently add the par-boiled potatoes to the smoking hot fat in a single layer, ensuring they don’t overcrowd the pan. They should sizzle immediately upon contact.
13. Turn the potatoes over to coat them evenly in the hot fat.
14. Return the roasting pan to the oven and roast for 1 hour 15 minutes to 1 hour 30 minutes, or until the potatoes are golden brown and crispy. Turn them two or three times during cooking to ensure even browning on all sides.
15. The potatoes are ready when they are deeply golden, crisp, and easily pierced with a fork.
16. Remove the roast potatoes from the oven and immediately sprinkle with freshly milled sea salt. Serve piping hot.

Expert Tips & Tricks

• The type of fat matters. Goose or duck fat will give you the most flavorful and crispy results. Vegetable oil is a perfectly acceptable substitute, especially for vegan diets, but be sure to use one with a high smoke point.
• Don’t overcrowd the pan. Overcrowding will steam the potatoes rather than roast them, resulting in soggy bottoms. Use two pans if necessary.
• High heat is key. A hot oven ensures the potatoes crisp up quickly without absorbing too much fat. If your oven struggles to maintain a consistent temperature, consider turning up the heat for the last 15 minutes of cooking.
• Don’t be afraid to experiment with seasonings. While sea salt is essential, feel free to add other herbs and spices like rosemary, thyme, garlic powder, or smoked paprika for extra flavor. Add these during the last 15 minutes of cooking to avoid burning.
• If the potatoes are not crispy enough by the end of the cooking time, turn on the broiler/grill for the last 5 minutes, watching them carefully to prevent burning.
• To get ahead, the potatoes can be par-boiled and shaken earlier in the day and stored in the fridge, ready to roast when needed.

Serving & Storage Suggestions

Serve your perfect roast potatoes immediately, while they are still sizzling hot and crispy. They are the ideal accompaniment to a traditional Sunday roast, alongside roasted meat, vegetables, and gravy. Leftover roast potatoes can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, spread them in a single layer on a baking sheet and bake in a preheated oven at 180°C/350°F until heated through and crispy again. Reheating in a frying pan with a little extra oil can also work well. Freezing roast potatoes is not recommended, as they tend to lose their crispness and texture upon thawing.

Variations & Substitutions

• Vegan Roast Potatoes: Substitute goose or duck fat with a high-quality vegetable oil like sunflower, rapeseed, or avocado oil.
• Garlic Roast Potatoes: Add 2-3 crushed garlic cloves to the roasting pan along with the fat.
• Herb-Infused Roast Potatoes: Toss the par-boiled potatoes with chopped fresh rosemary, thyme, or sage before adding them to the roasting pan.
• Spicy Roast Potatoes: Add a pinch of chili flakes or a dash of hot sauce to the fat for a spicy kick.
• Sweet Potato Roast Potatoes: Use sweet potatoes instead of regular potatoes for a sweeter, slightly caramelized flavor. Adjust the cooking time as needed.
• Crushed Roast Potatoes: After par-boiling, lightly crush each potato with a fork before roasting. This creates even more crispy edges.

FAQs (Frequently Asked Questions)

Q: Why is it important to par-boil the potatoes?
A: Par-boiling softens the potatoes and creates a fluffy interior, while also roughening the edges for maximum crispiness during roasting.

Q: Can I use olive oil instead of goose or duck fat?
A: While you can use olive oil, it has a lower smoke point than goose or duck fat, which can affect the crispiness of the potatoes. Vegetable oil is a better alternative for a vegan option.

Q: How do I prevent the potatoes from sticking to the pan?
A: Ensure the fat is smoking hot before adding the potatoes and don’t overcrowd the pan. Turning the potatoes occasionally during cooking will also help prevent sticking.

Q: What type of potatoes are best for roasting?
A: Floury potatoes like Maris Piper, King Edward, or Russet are ideal for roasting, as they have a high starch content that creates a fluffy interior and crispy exterior.

Q: Can I roast the potatoes at a lower temperature for longer?
A: Roasting at a lower temperature for longer will result in softer potatoes, rather than crispy ones. High heat is essential for achieving the desired texture.
