Why These Roast Potatoes Are the Best You’ll Ever Make

These aren’t your average oven-baked potatoes. What sets this recipe apart is its combination of science-backed technique and flavor-forward ingredients. By parboiling the potatoes in alkaline water, you create a starchy surface that turns irresistibly crunchy. Using infused fats—like olive oil, duck fat, or beef drippings—adds layers of flavor. The result? Potatoes that are crisp, creamy, and unforgettable.

Ingredients That Make It Work

• Russet or Yukon Gold Potatoes: Russets yield crispier edges and fluffier centers, while Yukon Golds bring a richer, creamier bite.
• Baking Soda: Elevates the pH of boiling water, helping break down the potato surface to enhance crispiness.
• Kosher Salt: Essential for seasoning during boiling and finishing for flavor boost.
• Olive Oil, Duck Fat, or Beef Fat: Adds depth, richness, and helps crisp the exterior.
• Fresh Rosemary: Earthy and aromatic, rosemary pairs perfectly with golden potatoes.
• Garlic: Lightly browned in fat to add savory aroma and flavor.
• Black Pepper: Adds just the right amount of kick to balance the richness.
• Fresh Parsley: A pop of freshness and color for the finished dish.

Smart Swaps for Common Dietary Needs

• Red Potatoes Instead of Russets: Use only if you prefer softer interiors—note that they may lose crispness quickly.
• Vegetarian or Vegan: Stick with extra-virgin olive oil instead of animal fats.
• No Fresh Herbs?: Dried rosemary and garlic powder can substitute in a pinch, though fresh will always offer better results.
• Infused Oils: Garlic-infused avocado oil is a great alternative for a nutty twist and extra crispiness.

Step-by-Step Guide to Perfect Crispy Roast Potatoes

Preheat the Oven
Set your oven to 450°F (or 400°F if using convection) with the rack in the center. A hot oven is key to achieving that signature crispy exterior.
Prepare the Potatoes
Peel and cut 4 pounds of russet or Yukon Gold potatoes into large chunks—quarters, sixths, or eighths depending on their size. Bigger chunks allow for better contrast between the crust and the soft center.
Boil with Alkaline Water
In a large pot, bring 2 quarts of water to a boil. Add 2 tablespoons kosher salt and ½ teaspoon baking soda. Toss in the potatoes and simmer until a knife slides in with minimal resistance—about 10 minutes.
Infuse the Fat
While the potatoes cook, gently heat your fat of choice (olive oil, duck fat, or beef fat) with minced garlic, chopped rosemary, and a few grinds of pepper. Once the garlic turns golden, strain the mixture—saving both the flavored oil and the solids separately.
Rough Up the Potatoes
Drain the potatoes and let them sit in the pot for 30 seconds. Transfer to a bowl and toss with the strained infused oil, using rough movements to coat and slightly mash the exteriors. This paste-like coating is the secret to ultra-crispy roast potatoes.
Roast Until Deeply Golden
Spread the coated chunks on a rimmed baking sheet without overcrowding. Roast undisturbed for 20 minutes. Then flip with a spatula and roast for another 30–40 minutes, flipping and shaking a couple of times for even browning.
Finish with Herbs and Garlic
Once perfectly golden and crisp, toss the roasted potatoes with the reserved garlic and rosemary solids and a handful of minced parsley. Season with more salt and pepper to taste and serve immediately.

Kitchen Hacks for Roasting Success

• Avoid Moving Too Early: Let potatoes roast untouched for at least 20 minutes to avoid sticking.
• Don’t Overcrowd the Pan: A single layer ensures crisp edges all around.
• Make-Ahead Tip: Parboil and toss with oil earlier in the day. Roast just before serving for best results.
• Storage: Store leftovers in an airtight container. Reheat in a 425°F oven for 10–15 minutes to restore crispiness.

Perfect Pairings and Tasty Twists

• Pair With: Roast chicken, steak, or a hearty lentil stew for a balanced meal.
• Serve Alongside: Garlic aioli, truffle mayo, or sour cream and chive dip.
• Spicy Kick: Toss with chili flakes or smoked paprika during the final 10 minutes of roasting.
• Cheesy Upgrade: Sprinkle with grated Parmesan just before the last flip for extra savoriness.
• Gluten-Free Delight: Naturally gluten-free, these crispy roast potatoes are perfect for celiac-friendly menus.

FAQs About Crispy Roast Potatoes

How do I keep my roast potatoes crispy after cooking?

To maintain that irresistible crunch, avoid covering the potatoes after roasting, as trapped steam can soften them. If making ahead, reheat uncovered in a 425°F oven for 10–15 minutes to restore crispiness. Store leftovers in an airtight container without stacking to preserve texture.

Can I make crispy roast potatoes in advance?

Yes! You can parboil and coat the potatoes in the infused fat up to 6 hours ahead of time. Store them in the fridge spread out on a tray. When ready to roast, bring them to room temperature for 20 minutes and roast as usual for maximum crispiness.

What’s the best oil or fat for extra crispy roast potatoes?

While extra-virgin olive oil works beautifully, duck fat and beef drippings provide unmatched richness and deeper browning. For a bold, savory flavor, go with animal fats. For a lighter, plant-based alternative, garlic-infused olive oil delivers excellent results.

Why are my roast potatoes sticking to the pan?

Potatoes can stick if flipped too early. Let them roast undisturbed for the first 20 minutes to allow the crust to set. Use a thin metal spatula to gently lift them from the pan when flipping, and make sure your baking sheet is well-oiled or preheated.
