Key Ingredient Notes
The success of your ultimate crispy roasted potatoes depends heavily on the type of potato you choose and the fat you use for roasting. Not all potatoes are created equal in the eyes of the oven.
The Potato Variety
For the ultimate crispy roasted potatoes, you want a high-starch potato. Russets or Yukon Golds are the gold standard here. Russets provide the absolute crunchiest exterior because of their high starch content, while Yukon Golds offer a beautiful buttery flavor and a slightly creamier interior. Avoid waxy potatoes like red or new potatoes if you want that thick, craggy crust, as they tend to hold their shape too well and won’t produce the necessary starch slurry.
The Role of Baking Soda
Adding half a teaspoon of baking soda to your boiling water is a game-changer for ultimate crispy roasted potatoes. The alkaline environment breaks down the potato’s pectin and draws starch to the surface. This creates a fuzzy, mashed-potato-like layer on the outside of each chunk after you shake them in the pot. Once that layer hits the hot fat in the oven, it dehydrates and browns, creating the ultimate crispy roasted potatoes texture.
The Fat Choice
While extra virgin olive oil works well, using duck fat, beef tallow, or even clarified butter (ghee) takes these ultimate crispy roasted potatoes to a whole new level. These fats have higher smoke points and incredible flavor profiles that infuse into the crust. If you are keeping it vegan, a high-quality neutral oil like avocado oil or a robust olive oil is your best bet for achieving those ultimate crispy roasted potatoes.

Step-by-Step Guide with Pro Tips
Making ultimate crispy roasted potatoes requires a bit more effort than just throwing chopped veg on a tray, but the results are worth every second. Follow these steps for guaranteed success.
Preparation and Boiling
Start by peeling your potatoes and cutting them into large, even chunks. Aim for about two-inch pieces. Small pieces will vanish into nothing, while large chunks provide that satisfying contrast between the shell and the fluff. Place them in a large pot of cold water—always start with cold water to ensure even cooking. Add a generous amount of salt and that crucial half-teaspoon of baking soda. Bring it to a boil and cook until the exteriors are softening but the centers still have a bit of bite. This is the first step toward the ultimate crispy roasted potatoes.
The Rough-Up Method
Once drained, let the potatoes sit in the pot for a minute to allow excess steam to evaporate. Now comes the fun part: put the lid on and shake the pot vigorously. You want the edges of the potatoes to look battered and fuzzy. This roughened surface area is what transforms into the crunch in your ultimate crispy roasted potatoes. At this point, you can add your fat and seasonings. Ensure every single piece is coated in a thick layer of starchy paste and oil.
The Roasting Process
Preheat your roasting pan in a 450°F (230°C) oven before adding the potatoes. When the potatoes hit the hot pan, you should hear a sizzle. Spread them out so they aren’t touching; crowding the pan will cause them to steam rather than roast, ruining your chances of achieving ultimate crispy roasted potatoes. Roast for at least 40 to 50 minutes, turning them every 15 minutes. This ensures that every side gets equal exposure to the heat and the oil, resulting in a uniform golden brown color for your ultimate crispy roasted potatoes.
Variations & Serving Suggestions
These ultimate crispy roasted potatoes are incredibly adaptable. For a Mediterranean twist, toss them with dried oregano, lemon zest, and crumbled feta right before serving. If you want something smoky, add a teaspoon of smoked paprika to the oil before coating. These potatoes also pair beautifully with bold proteins. For example, they are the perfect side for The Ultimate Savory Chicken Wing Dry Rub for Smoking if you are hosting a backyard barbecue. The smokiness of the wings complements the earthy, salty crunch of the ultimate crispy roasted potatoes perfectly.
For leftovers, which are rare, ensure you store them in high-quality containers like the Basics Glass Food Storage to keep them fresh, though you will want to reheat them in the oven or an air fryer to regain that signature ultimate crispy roasted potatoes texture. Microwaving will unfortunately make them soft.

FAQs
Why are my roasted potatoes not crispy?
The most common reasons for soggy potatoes are crowding the pan, which causes steaming, or not parboiling them first to create a starchy surface layer. Ensure you use a high-starch potato like Russets and give them plenty of space on the baking sheet.
Can I make these ultimate crispy roasted potatoes ahead of time?
While they are best fresh, you can parboil and roughen them up a few hours in advance. Store them at room temperature and do the final roast right before serving. To reheat leftovers, use an air fryer or oven to restore the crunch.
Does the type of fat matter for the crunch?
Yes! Animal fats like duck fat or beef tallow provide a superior crunch and flavor, but high-quality olive oil or avocado oil also work well. Avoid butter with high water content as it can lead to softer potatoes unless clarified.

Ultimate Crispy Roasted Potatoes
A foolproof method to achieve the crunchiest roasted potatoes with a fluffy, light interior using the baking soda technique.
- Total Time: 1 hour 5 minutes
- Yield: 6 servings 1x
Ingredients
4 lbs Russet or Yukon Gold potatoes, peeled and quartered
1/2 teaspoon baking soda
1 tablespoon kosher salt (plus more for boiling)
1/2 cup extra virgin olive oil or duck fat
2 tablespoons fresh rosemary, finely chopped
4 cloves garlic, minced
1/2 teaspoon freshly cracked black pepper
Instructions
Step 1: Preheat your oven to 450°F (230°C) and place a large rimmed baking sheet inside to heat up.
Step 2: Place the potato chunks in a large pot and cover with cold water by at least an inch. Add a handful of salt and the baking soda.
Step 3: Bring to a boil over high heat, then reduce to a simmer. Cook for about 10 minutes, or until a knife meets little resistance on the exterior but the potato is still firm in the middle.
Step 4: Drain the potatoes and let them sit in the pot for 1 minute to dry. Shake the pot vigorously until a thick layer of mashed potato-like paste builds up on the edges of the chunks.
Step 5: In a small saucepan, heat the oil or fat with the rosemary, garlic, and pepper over medium heat until the garlic starts to turn golden. Strain the oil over the potatoes (reserve the garlic/herbs for later).
Step 6: Toss the potatoes in the oil until thoroughly coated. Carefully spread them onto the preheated baking sheet in a single layer.
Step 7: Roast for 45-50 minutes, turning with a spatula every 15 minutes, until deep golden brown and incredibly crispy. Toss with the reserved garlic and rosemary in the last 5 minutes of roasting.
Step 8: Season with extra salt if needed and serve immediately.
Notes
Using baking soda is essential for the starch slurry. Do not skip the pot-shaking step!
