Serving Size: 6-8 servings
Prep Time: 15 minutes
Cook Time: 45 minutes
Total Time: 1 hour
Ingredients
- 3 pounds russet or Yukon Gold potatoes
- 1/4 cup vegetable oil or duck fat
- 1 teaspoon coarse sea salt
- 1/2 teaspoon black pepper
- 4 garlic cloves, unpeeled and lightly crushed
- 3 fresh rosemary sprigs
- 3 fresh thyme sprigs
- 2 tablespoons butter
- 1 tablespoon all-purpose flour (optional, for extra crispiness)
- Water for boiling
Selecting and Preparing the Potatoes
Choose potatoes that are similar in size for even cooking. Russet potatoes create the fluffiest interiors with excellent crispy exteriors, while Yukon Gold potatoes offer a creamier texture with equally good crisping potential. Avoid waxy varieties like red potatoes, as they don’t achieve the same fluffy interior texture.
Peel the potatoes and cut them into evenly sized chunks, roughly 2 to 3 inches in diameter. Try to make the pieces uniform so they cook at the same rate. Don’t make them too small, as they need enough mass to stay fluffy inside while developing that crispy crust outside.
Rinse the cut potatoes in cold water to remove excess starch, then pat them completely dry with paper towels or a clean kitchen towel.
The Parboiling Process
Place the cut potatoes in a large pot and cover with cold salted water by about 2 inches. Add 1 tablespoon of salt to the water, which helps season the potatoes and raises the boiling point for more even cooking.
Bring the water to a boil over high heat, then reduce to maintain a steady boil. Cook the potatoes for 8 to 10 minutes, until they’re just becoming tender around the edges but still hold their shape. You want them partially cooked but not falling apart.
The potatoes are ready when a knife slides in with slight resistance but doesn’t go through completely. This partial cooking is crucial for creating the fluffy interior while allowing the surfaces to roughen up for maximum crispiness.
Creating Rough Surfaces for Extra Crispiness
Drain the potatoes thoroughly in a large colander and let them sit for 2 to 3 minutes to allow excess moisture to evaporate. This step is important because wet potatoes won’t crisp properly.
While the potatoes are still in the colander, give them a good shake to rough up the surfaces. You can also gently toss them with a wooden spoon. This roughening creates more surface area that will become beautifully crispy during roasting.
For even more texture, you can lightly dust the roughened potatoes with flour, tossing to coat evenly. The flour creates additional crispy bits, though this step is optional.
Preparing for High-Heat Roasting
Preheat your oven to 425 degrees Fahrenheit. Place a large roasting pan or rimmed baking sheet in the oven while it preheats. This ensures the pan is hot when you add the potatoes, which helps with immediate crisping.
Pour the vegetable oil or duck fat into the hot roasting pan and let it heat for 2 to 3 minutes until it’s shimmering and very hot. Duck fat creates exceptional flavor and crispiness, but vegetable oil works perfectly well too.
The Roasting Process
Carefully add the prepared potatoes to the hot oil in a single layer. You should hear them sizzle immediately, which means the oil is at the right temperature. Turn each potato to coat with the hot oil, using tongs or a spatula to avoid splattering.
Season the potatoes generously with salt and pepper, then add the lightly crushed garlic cloves and fresh herb sprigs around the potatoes. The herbs will infuse the oil and potatoes with wonderful aromatic flavor.
Achieving Golden Perfection
Roast the potatoes for 20 minutes without moving them, allowing the bottom surfaces to develop a golden crust. After 20 minutes, carefully turn each potato using tongs or a spatula, exposing a new surface to the hot pan.
Continue roasting for another 15 to 20 minutes, turning once more if needed to ensure even browning on all sides. The potatoes are done when they’re deep golden brown and crispy on the outside, and a knife slides easily through the center.
In the final 5 minutes of roasting, add small pieces of butter around the potatoes for extra richness and flavor. The butter will brown slightly and add a nutty taste to the finished potatoes.
Testing for Doneness
Perfect roast potatoes should have a deep golden-brown color with visible crispy edges and rough, textured surfaces. When you tap them with a spoon, they should sound hollow and feel crispy on the outside.
The interior should be completely tender and fluffy when pierced with a knife. If they need more time, continue roasting in 5-minute intervals until they reach the perfect texture.
Serving Your Roast Potatoes
Remove the roast potatoes from the oven and let them rest in the pan for 2 to 3 minutes to finish crisping. Transfer them to a warm serving dish, leaving behind the herb sprigs and garlic cloves, though some people enjoy eating the roasted garlic.
Sprinkle with a final pinch of coarse sea salt while they’re still hot to enhance the flavor and add a pleasant textural contrast to the crispy surfaces.
Keeping Them Crispy
Roast potatoes are best served immediately while they’re at their crispiest. If you need to keep them warm for a short time, place them on a wire cooling rack set over a baking sheet in a low oven (200 degrees Fahrenheit) to prevent them from steaming and losing their crispiness.
Avoid covering roast potatoes with foil or placing them in a covered dish, as the trapped steam will make them soggy.
Make-Ahead Tips
You can parboil the potatoes up to 2 hours ahead of time and leave them in the colander to dry out even more, which actually improves the final crispiness. Just make sure to rough them up right before roasting.
For larger gatherings, you can double this recipe, but use two separate roasting pans to avoid overcrowding, which would cause the potatoes to steam rather than crisp.
Flavor Variations
While the classic herb combination of rosemary and thyme is traditional and delicious, you can experiment with different seasonings. Try adding smoked paprika for a smoky flavor, or toss the hot potatoes with grated Parmesan cheese and fresh parsley for an Italian twist.
Some cooks like to add a splash of white wine vinegar or lemon juice to the hot potatoes just before serving for a bright acidic contrast to the rich, crispy exterior.
Troubleshooting Common Issues
If your potatoes aren’t getting crispy enough, make sure your oven temperature is accurate and the oil was properly heated before adding the potatoes. Overcrowding the pan is another common cause of soggy potatoes.
If the potatoes are browning too quickly on the outside but aren’t tender inside, reduce the oven temperature to 400 degrees and continue cooking until the interiors are fluffy.
Perfect Pairings
These crispy roast potatoes pair beautifully with virtually any roasted meat, from beef and lamb to chicken and pork. They’re essential for traditional Sunday roast dinners and make an excellent side dish for holiday meals.
The combination of crispy exterior and fluffy interior also makes them perfect for breakfast or brunch, served alongside eggs and bacon for a hearty, satisfying meal.
These perfect crispy roast potatoes deliver everything you want in this classic side dish: golden, crunchy exteriors that give way to fluffy, tender centers bursting with flavor. Master this technique, and you’ll have a recipe that transforms every meal into something special and memorable.
