These aren’t just good roast potatoes—they’re the crispiest, most flavorful roasted potatoes you’ll ever make. With a perfectly fluffy interior and a golden, crunchy exterior, these potatoes elevate any meal from ordinary to extraordinary. The secret lies in a special boiling technique and infused oil that takes these humble spuds to restaurant-quality status in just over an hour, making them perfect for Sunday dinners or special occasions.

Why You’ll Love This Recipe

  • Game-Changing Texture: The contrast between the shatteringly crisp exterior and cloud-like fluffy interior is simply unbeatable.
  • Foolproof Method: While it might look fancy, this recipe breaks down into simple steps that guarantee perfect results every time.
  • Flavor-Packed: The infused oil with rosemary and garlic adds incredible depth of flavor without overwhelming the natural potato taste.
  • Versatile Side Dish: These potatoes pair beautifully with nearly everything—from a simple roast chicken to an elaborate holiday feast.

Ingredients You’ll Need

  • Russet or Yukon Gold potatoes: The higher starch content in these varieties creates that perfect fluffy interior. Russets give you a slightly fluffier texture, while Yukon Golds offer a naturally buttery flavor.
  • Baking soda: The not-so-secret weapon that helps break down the potato surface, creating more texture for ultimate crispiness.
  • Extra-virgin olive oil, duck fat, goose fat, or beef fat: Your choice of fat makes a big difference—duck or goose fat will give you the most luxurious flavor, but olive oil works beautifully too.
  • Fresh rosemary: Provides aromatic, woodsy notes that perfectly complement the potatoes. Always use fresh for this recipe, not dried.
  • Garlic: Infuses the oil with rich flavor without burning or becoming bitter.
  • Kosher salt: More than just seasoning—the salt in the boiling water helps flavor the potatoes from the inside out.
  • Fresh parsley: Adds a bright, fresh finish to balance the rich, savory potatoes.
  • Black pepper: Provides subtle heat and depth of flavor.

Note: You’ll find the complete list of ingredients, along with their exact measurements, in the printable recipe card at the bottom of this post.

Variations

  • Herb Swap: Replace rosemary with thyme or sage for a different aromatic profile.
  • Spice It Up: Add a teaspoon of smoked paprika or cayenne pepper to the oil for heat.
  • Cheesy Finish: Toss the hot potatoes with a handful of grated Parmesan cheese before serving.
  • Truffle Upgrade: Drizzle with a small amount of truffle oil just before serving for an elegant twist.
  • Lemon Zest: Add the zest of one lemon with the parsley at the end for a bright citrus note.

How to Make The Best Crispy Roast Potatoes

Step 1: Prepare and Boil the Potatoes

Preheat your oven to 450°F (or 400°F if using convection). Bring 2 quarts of water to a boil in a large pot. Add 2 tablespoons of kosher salt, the baking soda, and the potato chunks. Return to a boil, then reduce to a simmer. Cook for about 10 minutes until the potatoes are just tender when poked with a knife.

Step 2: Create the Infused Oil

While the potatoes are cooking, combine your chosen fat with the rosemary, garlic, and black pepper in a small saucepan over medium heat. Cook for about 3 minutes, stirring constantly, until the garlic just starts to turn golden. Immediately strain through a fine-mesh strainer, saving both the infused oil and the garlic-rosemary mixture separately.

Step 3: Rough Up the Potatoes

Drain the potatoes carefully and let them sit in the pot for about 30 seconds to evaporate excess moisture. Transfer them to the bowl with your infused oil, season with salt and pepper, and toss roughly. You’re actually trying to create a starchy coating on the outside of each potato piece—this is the magic step that creates the incredible crispy exterior!

Step 4: Roast to Perfection

Spread the potatoes out evenly on a large rimmed baking sheet, making sure they’re not touching. Roast without disturbing for 20 minutes, then use a thin metal spatula to release any stuck potatoes and turn them. Continue roasting for 30-40 minutes more, turning occasionally, until deeply golden brown and crisp all over.

Step 5: Final Flavor Boost

Transfer the hot, crispy potatoes to a large bowl and toss with the reserved garlic-rosemary mixture and the fresh parsley. Season with additional salt and pepper to taste, and serve immediately while hot and crunchy.

Pro Tips for Making the Recipe

  • Don’t Skip the Baking Soda: It creates an alkaline environment that helps break down the exterior of the potatoes for maximum crispiness.
  • Proper Boiling Time: Cook the potatoes just until tender but not falling apart—overboiling will make them too soft to get crispy.
  • Adequate Spacing: Make sure the potatoes aren’t crowded on the baking sheet; they need room to release steam and crisp up.
  • The Rough Toss: Really shake those potatoes with the oil to create that starchy exterior coating—it’s what transforms good potatoes into great ones.
  • High Heat Is Key: Don’t be tempted to lower the oven temperature—that high heat creates the contrast between crispy exterior and fluffy interior.

How to Serve

These potatoes are surprisingly versatile and complement almost any main dish:

Perfect Pairings:

  • Serve alongside a beautiful roast chicken or beef tenderloin for Sunday dinner
  • Accompany with grilled steak and a simple green salad
  • Partner with baked fish and steamed vegetables for a lighter meal
  • Offer as an elevated side for holiday feasts with turkey or ham

Sauce Options:

A good crispy potato can stand on its own, but for dipping enthusiasts, consider:

  • Classic aioli
  • Herb-infused sour cream
  • Tangy yogurt sauce with lemon and herbs

Make Ahead and Storage

Storing Leftovers

Store leftovers in an airtight container in the refrigerator for up to 3 days. The potatoes will lose their crispiness but will still taste delicious.

Freezing

These potatoes don’t freeze well after cooking—the texture becomes compromised. However, you can par-boil the potatoes, cool them completely, then freeze before the roasting stage for up to 1 month.

Reheating

For the best results when reheating, place potatoes on a baking sheet in a single layer in a 400°F oven for 10-15 minutes. Avoid microwaving as this will make them soggy.

FAQs

  1. Can I make these potatoes without parboiling them first?

    The parboiling step is crucial for developing the starchy exterior that creates the ultimate crispy finish. Skipping this step will result in potatoes that are crisp on the outside but not nearly as special. The baking soda in the water is the real game-changer here, creating tiny cracks and roughness on the surface of each potato piece.

  2. Why did my potatoes stick to the baking sheet?

    This usually happens if the baking sheet wasn’t hot enough when you added the potatoes or if you tried to turn them too early. Make sure your oven is fully preheated, and don’t disturb the potatoes for the first 20 minutes of roasting. Using a thin metal spatula also helps release them without damaging that precious crispy coating.

  3. Can I use dried herbs instead of fresh?

    Fresh herbs really do provide the best flavor here, especially since they’re being infused into the oil. If you absolutely must use dried, use only 1/3 the amount called for fresh herbs, but know that the aromatic quality will be diminished. For the finishing parsley, if using dried, skip it altogether rather than substituting.

  4. Is duck fat really worth it for this recipe?

    While olive oil produces excellent results, animal fats like duck fat take these potatoes to an entirely different level with a richer flavor and even crispier exterior. If you’re making these for a special occasion, splurging on duck fat is absolutely worth it—especially if you want to experience the fullest potential of this recipe.

Final Thoughts

These truly are the best crispy roast potatoes you’ll ever make—a bold claim that they absolutely live up to. The method might seem fussy at first glance, but each step serves a purpose in creating potatoes with an unrivaled texture and depth of flavor. Make these once, and I guarantee they’ll become your signature side dish, the one friends and family request time and again. There’s something magical about the humble potato transformed this way—proving that sometimes the simplest ingredients, prepared with care and a few clever techniques, create the most memorable dishes.

Ingredients

Scale

Potatoes

    • 4 pounds (about 2 kg) russet or Yukon Gold potatoes, peeled and cut into quarters, sixths, or eighths
    • 2 quarts (2 L) water
    • 2 tablespoons kosher salt (about 1 ounce; 25g), plus more to taste
    • 1/2 teaspoon (4 g) baking soda
    • Freshly ground black pepper, to taste

Infused Oil

    • 5 tablespoons (75 ml) extra-virgin olive oil, duck fat, goose fat, or beef fat
    • 3 medium cloves garlic, minced
    • Small handful fresh rosemary leaves, picked and finely chopped

Finishing

  • Small handful fresh parsley leaves, minced
  • More kosher salt and black pepper to taste

Instructions

  1. Preheat and Boil Potatoes: Adjust your oven rack to the center and preheat to 450°F (230°C) or 400°F (200°C) if using convection. Bring 2 quarts of water to a boil in a large pot. Add 2 tablespoons kosher salt, the baking soda, and the peeled, cut potatoes. Stir and return to a boil. Lower heat to a simmer and cook the potatoes until a knife meets little resistance (about 10 minutes after boiling).
  2. Infuse the Oil: While the potatoes cook, combine the oil (or chosen fat) with rosemary, minced garlic, and a few grinds of black pepper in a small saucepan. Cook over medium heat, stirring and shaking the pan constantly, until the garlic just begins to turn golden (about 3 minutes). Immediately strain the oil through a fine-mesh strainer into a large bowl, reserving the solids separately.
  3. Drain and Rough Up Potatoes: Once the potatoes are cooked, drain carefully, and let them rest in the pot for 30 seconds to allow excess moisture to evaporate. Transfer potatoes to the bowl with the infused oil. Season with additional salt and pepper. Toss vigorously until a thick layer of mashed potato–like paste coats the potato chunks, roughing up their surfaces.
  4. Roast the Potatoes: Spread potatoes out evenly on a large, rimmed baking sheet. Roast without moving for 20 minutes. Then, using a thin spatula, release any stuck potatoes and shake the pan to turn them. Continue roasting, turning and shaking the potatoes a few times, for another 30 to 40 minutes, until deeply browned and crisp all over.
  5. Finish and Serve: Transfer the hot potatoes to a large bowl. Add the reserved garlic/rosemary mixture and minced parsley. Toss to coat and season with more salt and pepper to taste. Serve immediately.

Notes

  • Cut potatoes into similar sizes to ensure even cooking.
  • Use Yukon Gold for creamier texture or Russets for maximum crispness.
  • For best flavor, use animal fat (duck, goose, or beef) if available.
  • Don’t skip the boiling with baking soda; it helps create an extra-crisp exterior.
  • Serve immediately for peak crispiness as potatoes will soften slightly as they sit.
