The Baking Soda Trick for Crispy Roasted Potatoes
Discover the baking soda trick to achieve the crispiest oven-roasted potatoes. Perfect for elevating your side dishes with minimal effort!

Achieving crispy oven-roasted potatoes can be tricky, but a simple baking soda trick can transform your spuds into golden, crunchy delights. The right technique can elevate your side dish game, ensuring that every bite is satisfying and delicious.
Why Baking Soda?
When you add baking soda to the water, it increases the pH level, which helps to break down the potato's starches. This process forms a rougher surface on the potato, allowing for better crisping when roasted.
Steps to Crispy Oven-Roasted Potatoes
- Choose Your Potatoes: Use starchy potatoes like Russets or Yukon Golds for the best results.
- Prepare the Potatoes:
- Peel (if desired) and cut the potatoes into even-sized chunks, about 1-2 inches.
- Boil the Potatoes:
- In a large pot, bring water to a boil. Add 1/2 teaspoon of baking soda per quart of water.
- Carefully add the potatoes and boil for 8-10 minutes until slightly tender.
- Drain and Rough Up:
- Drain the potatoes and let them sit for a few minutes. Gently shake the pot or use a spoon to roughen the surfaces for maximum crispiness.
- Preheat Your Oven: Set your oven to 425°F (220°C) for optimal roasting.
- Season and Roast:
- Toss the roughened potatoes with olive oil, salt, and your favorite seasonings. Spread them evenly on a baking sheet.
- Roast for 30-40 minutes, flipping halfway through, until golden and crispy.
Pro Tips
- Use a Hot Baking Sheet: For extra crispiness, preheat your baking sheet in the oven before adding the potatoes.
- Dry Thoroughly: Ensure your potatoes are completely dry after boiling; moisture can lead to steaming instead of roasting.
- Space Them Out: Avoid overcrowding the pan to promote even browning and crispiness.
Safety Note
When working with hot oil, be cautious to avoid splattering. Always use oven mitts when handling hot pans to prevent burns.
Conclusion
Try the baking soda trick the next time you roast potatoes for a crunchy, irresistible side dish. With just a few simple steps, you can achieve restaurant-quality results right at home.
