Crispy roasted potatoes

We’re not big potato fans at our house. In fact, it’s not often we get potatoes for dinner, but that may change now that we’ve finally found the recipe for the perfect crispy oven-roasted potatoes. These crispy potatoes in the oven with rosemary and oregano, are really the ultimate crispy oven potato. Yum! I love them. So did the rest of the family, by the way!

This recipe is a method of making delicious crispy potatoes in the oven, which you must promise me to try. First, the potatoes must be pre-cooked with baking soda in the water – it breaks down the starch and gives a surface of the potatoes that makes them super crispy in the oven.

Then the pre-cooked potatoes have to go in the oven with delicious oil until they become super crispy. Eventually, they are seasoned with rosemary, oregano, and garlic. These little rosemary potatoes are just SO good, and we’re never going to make crispy oven-roasted potatoes in any other way again.

Easy oven potatoes for the whole family

There may be an extra step in this recipe compared to the roasted potatoes you normally make, but once you’ve tried to cook them this way, you won’t do without this step.

It’s not a very difficult recipe, and once you have the technique and the secret ingredient in place, you can always make delicious potatoes for dinner.

All you need is:

  • Potatoes
  • Water,for pre-cooking
  • Baking soda (it’s the secret ingredient in this recipe)
  • Salt and pepper
  • Parsley
  • Spiced oil (which you can also easily make yourself!)

The secret behind these extremely crispy potatoes, as I said, is to cook them with baking soda. It breaks down the starch on the surface and makes them a bit dull.

It may not sound so nice, but it is actually this surface that gets quite crisp and delicious in the oven and gives a great result.

Dressing for roasted potatoes

You can use many different dressings for oven potatoes. We really like them with regular mayonnaise, a chili mayo, or a bearnaise mayo. They are also good with ketchup or a thick parsley sauce with a piece of fish.

Tips and tricks

  • Be sure to shake the cooked potatoes well in the bowl, to break down the surface. Don’t be afraid to destroy the surface – of course, they should not become totally smashed. But it’s the broken surface that makes them crispy in the oven.
  • If you want to make them for Christmas, you can only season them with salt and pepper, and use duck or turkey fat instead of oil.
  • Try with other spices, for example herbs de provence or thyme.


  • The potatoes are most crunchy and crispy if eaten immediately. You can easily store them for the next day in the fridge, but then they will be soft. Our recommendation is therefore to eat them immediately, and once you get started, it is not a difficult task.
