If you’ve ever pulled a tray of roasted potatoes out of the oven only to find them pale, soft, and a little sad… you’re not alone. For years, I thought soggy roasted potatoes were just part of life. Delicious, yes—but never great.
Everything changed the day I learned a small but game-changing trick. One of those kitchen secrets that sounds almost too simple, yet completely transforms the final result. The kind of tip you remember forever and pass on like a family treasure.
These oven-roasted potatoes are exactly that: crispy and golden on the outside, soft and fluffy on the inside. They’re the kind of potatoes people keep “taste-testing” straight from the pan. And once you try them this way, there’s really no going back.
Which Potatoes Are Best for Roasting?
If you’re aiming for roasted potatoes that are crispy on the outside and tender on the inside, choosing the right variety makes a big difference.
Yellow-fleshed potatoes and red potatoes are the best choices for oven roasting. Compared to white potatoes, they contain less starch, which means their flesh is naturally firmer and more compact. This texture holds up beautifully in the oven and makes it easier to achieve that perfect contrast between a golden crust and a soft center.
White potatoes, on the other hand, tend to be softer and more floury. They’re excellent for mashed potatoes, gnocchi, croquettes, and fillings of savory cakes — but they’re less reliable for roasting.
Yellow and red potatoes are also great for frying and pan-cooking, and they’re generally more forgiving if you’re looking for evenly cooked, crispy roasted potatoes.
Some popular yellow potato varieties to look for include Blondine Yellow, Spunta, Primura, Bintje, Jelly, Capuchine, German, and Penelope. Among red potatoes, good options are Cherie, Desiree, Yona, Stemster, Mozart, Sunred, Red Potatoes of Colfiorito IGP, and Zoe (which also has red flesh, not just red skin).
Once you’ve chosen the right potatoes, you’re already halfway to a perfect tray of oven-roasted potatoes.
Ingredients for These Perfect Roasted Potatoes
- Potatoes – choose starchy or all-purpose potatoes; peel them and cut into evenly sized chunks.
- Water – for boiling the potatoes.
- Baking soda – This is the secret ingredient that helps create an ultra-crispy exterior. Don’t omit it!
- Sea salt
- Garlic clove – peeled and finely minced; fresh garlic gives the best aroma.
- Extra virgin olive oil – use a good-quality olive oil for maximum flavor and crispiness.
- Fresh rosemary sprig – rinsed, dried, and finely chopped.
- Freshly ground black pepper.
How to Make Perfectly Crispy Oven-Roasted Potatoes
Prep the Potatoes Properly
Start by peeling the potatoes and cutting them into evenly sized chunks (1). Rinse them in a bowl of cold water, changing the water a few times, until it runs clear. This removes excess starch and helps prevent sogginess later on.
Boil with Baking Soda (The Secret Step)
Bring the water to a rolling boil in a large pot. Add the baking soda and salt, then carefully add the potatoes. Once the water returns to a boil, cook the potatoes for 5 minutes (2). Drain and immediately rinse the potatoes under cold running water. This stops the cooking and removes any excess baking soda taste.
Don’t skip boiling the potatoes, becouse you won’t get the same crispy exterior and fluffy interior.
Why add baking soda to the water? It breaks down the potato surface, creating a rough texture that turns extra crispy in the oven.
Season Generously
Transfer the potatoes to a large bowl. Add the olive oil, minced garlic, chopped rosemary, salt, and black pepper. Toss gently until every piece is well coated (3) and slightly rough around the edges—this texture is exactly what you want.
Roast Until Golden and Crispy
Preheat your oven to 240°C / 465°F. Arrange the potatoes in a single layer on a baking sheet (4), making sure they’re not crowded. Place the tray on the lower oven rack.
Bake for 20 minutes, then carefully turn each potato piece individually. Return to the oven and bake for another 10–15 minutes, until deeply golden and irresistibly crispy (5).
Remove from oven and let rest for 5 minutes, then serve hot, as a delicious side dish.

Storage Instructions
Roasted potatoes are best enjoyed fresh, but leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat in the oven or in a hot pan to restore crispiness. Avoid the microwave if possible.
Tips and Variations
- Extra crispy: Don’t overcrowd the baking tray—space is key.
- Herb swap: Try thyme or sage instead of rosemary.
- Garlic lovers: Add a second clove for a stronger flavor.
- No rosemary? Dried herbs work too, just use a smaller amount.
