Parboiling, roughing the surfaces, and roasting in very hot fat produce reliably crisp results that stand up to long feasts. Canonical URL: https://www.topshelf.recipes/recipes/crispy-roast-potatoes ## Author Jake Woods https://www.topshelf.recipes/chef/jake-woods Published: June 26, 2026 Last Updated: September 28, 2026 ## About This Recipe Crispy roast potatoes are one of those deceptively simple dishes that reward attention to technique rather than fancy ingredients. This version leans into three predictable moves — a brief parboil, a deliberate roughing of the edges, and roasting in very hot fat — to produce a deeply golden, crackly exterior and a cottony interior that can stand up to gravy, jus, or thick sauces. I favor Yukon Gold for its buttery flesh and Maris Piper when you want a drier, more distinct crumb; both respond beautifully to the baking soda trick and vigorous shaking that create more surface area to brown. The addition of butter with oil gives flavor without burning, and rosemary plus smashed garlic lend classic aromatics that flavor the fat as the potatoes roast. What sets this recipe apart is the choreographed downtime and heat: steaming off excess surface moisture in the warm pot concentrates starch on the surface so it crisps, and preheating the fat ensures immediate sizzle and blistering on contact. The method is forgiving — you can parboil several hours ahead and finish just before serving — and scalable for holiday tables. If you want reliably crisp, roast-potato perfection that holds up through service, these are the steps to commit to. ## Recipe Information - Prep Time: 25 minutes - Cook Time: 50 minutes - Total Time: 75 minutes - Servings: 12 - Difficulty: Medium - Category: Baking ## Ingredients ### Cut and parboil the potatoes - 3 lb Yukon Gold or Maris Piper potatoes, peeled and cut into 1½–2 inch pieces - 8 cups Water (enough to cover potatoes) - 2 tsp Kosher salt (for parboil and seasoning) - 1/4 tsp Baking soda (optional; helps roughen edges) ### Preheat oven and heat the fat - 6 tbsp High-heat oil (vegetable, canola, or duck/goose fat) - 2 tbsp Unsalted butter ### Roast the potatoes in the hot fat - 2 sprigs Fresh rosemary sprigs - 4 cloves Garlic cloves, smashed (skin left on if roasting in skin) - 1/2 tsp Freshly ground black pepper ## Ingredient Guide ### Maris Piper potatoes A British potato cultivar prized in the U.K. for roasting and making chips; it’s a fairly floury, dry potato that crisps on the outside and flakes nicely inside. Many home cooks in the U.S. may not encounter it in supermarkets outside specialty or import shops. Flavor is mild and starchy rather than buttery, and good substitutes are Yukon Gold (for a slightly waxier texture) or Russet/Idaho (for a drier, fluffier result). ### Duck/goose fat Rendered fat from duck or goose commonly used in French and British cooking to roast vegetables and confit meats; it has a rich, savory, slightly meaty aroma and helps produce an exceptionally crisp, golden exterior. It’s sold at specialty butchers, gourmet grocers, or online, and some upscale supermarkets carry tubs of it. Substitute with high-heat neutral oils (canola, peanut) for technique, or with lard, chicken schmaltz, or clarified butter for a richer flavor, noting each will impart different aromas and mouthfeel. ## Instructions ### 1. Cut and parboil the potatoes Place peeled, evenly sized potato pieces in a large pot and cover with cold water. Add 2 tsp kosher salt and 1/4 tsp baking soda, bring to a boil, then simmer 8–10 minutes until edges are starting to soften but centers are still firm when pierced. ### 2. Drain and roughen the edges Drain the potatoes in a colander and give them a vigorous shake or toss for 30–60 seconds to roughen the surfaces — this creates textured edges that crisp beautifully. Return potatoes to the (still-warm) empty pot for 1–2 minutes to let excess surface moisture steam off. ### 3. Preheat oven and heat the fat Heat the oven to 450°F (230°C). Put the oil and butter in a large heavy roasting pan and place it in the oven to heat until the fat is very hot and shimmering, 8–10 minutes (be careful — the pan will be extremely hot). ### 4. Roast the potatoes in the hot fat Carefully transfer the parboiled potatoes into the hot roasting pan and turn them once in the fat to coat. Scatter rosemary and smashed garlic among the potatoes, season with freshly ground pepper and a little extra salt if needed, then spread potatoes in a single layer. ### 5. Cook until deep golden and turn once Roast for 40–50 minutes, turning the potatoes with a spatula once or twice so all sides get brown and crisp. If needed, increase the oven to 475°F (245°C) for the last 5–8 minutes to deepen the crust. ### 6. Finish and serve immediately Remove the pan from the oven, discard rosemary stems and garlic skins if desired, and transfer potatoes to a warm serving dish. Sprinkle with flaky salt and serve immediately for best crunch. ## Nutrition Estimated nutrition per serving (1 serving): - Calories: 165 kcal - Protein: 2.3 g - Carbohydrates: 19.5 g - Fat: 8.8 g - Saturated Fat: 2.2 g - Fiber: 2.5 g - Sugar: 0.9 g - Added Sugars: 0 g - Cholesterol: 5 mg - Sodium: 337.2 mg - Potassium: 480.9 mg - Calcium: 15.5 mg - Iron: 0.9 mg - Vitamin D: 0 mcg ## Tips ### Parboil, don’t overcook Aim for tender edges with a firm center; 8–10 minutes is a guideline because pot size and potato variety change cooking speed. ### Use baking soda sparingly A quarter teaspoon roughens the surface by breaking down some starch — enough to promote craggy edges without making the potatoes gummy. ### Roughen for texture Shake the drained potatoes in a colander or toss them in the pot to knock off bits of starch and create nooks that capture fat and crisp up. ### Heat the fat thoroughly Put the oil and butter in the pan while the oven preheats so the fat is shimmering; cold fat means soggy, not crackly, potatoes. ### Single layer and space Crowding cools the fat and steams the potatoes; spread them in a single layer with a little breathing room for the best browning. ### Finish with high heat If the crust needs deepening, bump the oven to 475°F (245°C) for the last 5–8 minutes to intensify browning without drying the interior. ## Variations and Substitutions ### Duck or goose fat Swap all or part of the oil for rendered duck/goose fat for a richer, traditional roast-potato flavor—use the same high-heat method to crisp them. ### Herb and citrus finish Toss the hot potatoes with chopped parsley, lemon zest, and a splash of lemon juice after roasting for a brighter, fresher profile. ### Garlic-free or vegan Omit the smashed garlic and use all oil (no butter) to keep the dish vegan while still getting maximum crunch from the hot fat. ### Parmesan crust During the last 10 minutes, sprinkle grated Parmesan over the potatoes so it melts and forms a nutty, extra-crispy crust. ### Sweet potato adaptation Use firm sweet potatoes but reduce parboil time and roast at slightly lower temp (425°F) to avoid burning sugars; they won’t get as crackly but will caramelize beautifully. ## Notes These roast potatoes shine on a holiday table but are easy enough for a weeknight when you want a perfect crispy side. Expect a golden, crunchy exterior and a tender, fluffy center every time. ### Storage and Make-Ahead Store leftovers in an airtight container in the refrigerator for up to 3 days. Re-crisp in a 425°F oven or a hot skillet with a teaspoon of oil, turning occasionally; avoid microwaving, which makes them limp. You can parboil the potatoes a day ahead, drain and dry them, then keep covered in the fridge and roast from cold when ready. ### Serving Suggestions These potatoes pair beautifully with roast beef, roast chicken, or a herbaceous leg of lamb and stand up well to gravy and rich sauces. For a holiday plate, add a bright vegetable such as roasted Brussels sprouts with balsamic or a green pea purée to cut the richness; finish the potatoes with flaky salt and a scattering of chopped parsley. Serve with a medium-bodied red like Côtes du Rhône or a malty brown ale to balance the roasted flavors. ## Frequently Asked Questions ### Why add baking soda to the parboil? The small amount of baking soda raises the pH at the potato surface, breaking down some starches and promoting a rough, floury exterior that browns and crisps more readily. ### Can I skip the parboil and roast from raw? You can, but raw-roasted potatoes take much longer and rarely get the same fluffy interior; parboiling ensures the centers are cooked before the exterior is deeply browned. ### What potato variety is best? Yukon Gold gives a creamier, buttery interior and crisp exterior, while Maris Piper or other floury varieties yield a drier crumb and more pronounced flakiness; either works with this method. ### My potatoes browned unevenly — what happened? Uneven browning usually comes from crowding, uneven pan heat, or insufficiently hot fat; spread potatoes in a single layer and ensure the oil is shimmering before adding them. ### How do I get them crisp again after storing? Reheat on a baking sheet in a 425°F oven or in a hot skillet with a little oil, turning occasionally; this reactivates the fats and restores the crust far better than a microwave. ## Related Recipes and Guides - [Cloud Bread Sandwiches](https://www.topshelf.recipes/recipes/cloud-bread-sandwiches) - [Honey Mustard Chicken Nuggets](https://www.topshelf.recipes/recipes/honey-mustard-chicken-nuggets-baked) - [Cheddar Jalapeño Corn Muffins](https://www.topshelf.recipes/recipes/cheddar-jalapeno-corn-muffins) - [Basque Burnt Cheesecake](https://www.topshelf.recipes/recipes/basque-burnt-cheesecake-salted-caramel) - [30-Minute Sticky Baked Honey Garlic Chicken Thighs with Crisp Edges](https://www.topshelf.recipes/recipes/30-minute-sticky-baked-honey-garlic-chicken-thighs-crisp-edges) - [Lemon Butter Salmon](https://www.topshelf.recipes/recipes/lemon-butter-salmon) - [Baking Soda and Tenderized Beef](https://www.topshelf.recipes/articles/baking-soda-and-meat) - [Gluten-Free Weeknight Grilling Plan](https://www.topshelf.recipes/articles/gluten-free-weeknight-grilling-plan) - [Low-Fat Grill Swaps for Big Flavor](https://www.topshelf.recipes/articles/low-fat-grill-swaps-big-flavor)
