This recipe uses a handful of easy-to-find, simple ingredients that work harmoniously to deliver incredible flavor, texture, and color. Each one plays an essential role, from the baking soda that helps perfect the crisp to the olive oil that infuses rich taste and golden hues.

  • Potatoes (1 kg / 2 lbs): Use starchy varieties like Russet or Maris Piper for the best crispy results.
  • Olive oil (⅓ cup): Adds flavor and helps the potatoes crisp up beautifully in the oven.
  • Fresh rosemary (4 sprigs, optional): Brings wonderful aromatic notes that elevate the dish without overwhelming it.
  • Unpeeled garlic cloves (4, slightly flattened, optional): Infuse a subtle, mellow garlic essence during roasting.
  • Salt (to taste): Enhances all the natural flavors and balances the richness.
  • Baking soda (¼ tsp): The secret weapon that breaks down the potato skin to create that sought-after crispy texture.

How to Make Extra Crispy Oven-Roasted Potatoes Recipe

Step 1: Preheat and Prepare

Begin by heating your oven to a high temperature of 210°C (410°F). This high heat is essential for developing that golden crust. Also, make sure to pour your olive oil into a metal roasting tray and place it in the oven while it’s heating; this warm oil is the magic touch that crisps the potatoes perfectly when they hit the tray.

Step 2: Boil with Baking Soda

Bring a large pot of water to a rolling boil and add the baking soda. You’ll notice it fizzing just a bit – this is a good sign! The baking soda helps soften the skins and creates the texture contrast we’re after. Peel your potatoes while waiting for the water to boil, then gently add them in and boil for about 20 minutes until they are very soft but not falling apart.

Step 3: Rough Up the Potatoes

Drain the potatoes thoroughly and return them to the empty pot. Give them a gentle toss or bash using the pot’s side. This step roughens up the surface, allowing more edges to crisp up beautifully in the oven. Don’t worry if some potatoes break – this actually adds to the overall crispiness!

Step 4: Roast to Perfection

Carefully transfer the roughened potatoes into the hot olive oil in the roasting tray. Toss them through the oil so every surface is coated. Now, pop the tray in the oven. Roast for 1 to 1¼ hours, turning the potatoes every 15 minutes to brown them evenly. If using rosemary and garlic, add them about 15 to 30 minutes before finishing to let their fragrant flavors infuse without burning.

Step 5: Season and Serve

Once the potatoes reach that enviable golden crisp, discard the rosemary and garlic, sprinkle with salt to taste, and serve immediately. Timing is key here; serve hot to appreciate the full crunch and tender contrast of this Extra Crispy Oven-Roasted Potatoes Recipe.

How to Serve Extra Crispy Oven-Roasted Potatoes Recipe

A white rectangular baking dish with a dark blue rim holds nine golden brown roasted potato pieces evenly spaced inside. The potatoes have a crispy, slightly rough texture on their surfaces with some areas appearing more browned than others. Scattered among the potatoes are a few garlic cloves and fresh sprigs of rosemary, all resting in a small amount of light brown cooking oil with some browned bits. The baking dish sits on a white marbled surface, showing some golden stains around the edges from the cooking process. photo taken with an iphone --ar 4:5 --v 7

Garnishes

The beauty of this recipe is in its simplicity, but if you want to ramp up the flavor, sprinkle fresh chopped parsley or chives over the top just before serving. A light zest of lemon could add a refreshing brightness that complements the rich potatoes wonderfully.

Side Dishes

These potatoes are versatile enough to pair with a wide range of mains. Think juicy roasted chicken, grilled vegetables, or a crisp green salad. They also hold up well alongside heartier dishes like mushroom ragout or even a plant-based roast.

Creative Ways to Present

If you want to wow your guests, present these potatoes in a rustic cast-iron skillet straight from the oven or mound them artfully on a wooden board topped with a drizzle of herb-infused olive oil. Adding a sprinkle of sea salt flakes and freshly cracked black pepper right before serving adds a gourmet touch.

Make Ahead and Storage

Storing Leftovers

If you have any leftovers (which is rare!), place them in an airtight container in the fridge. They will keep well for up to 3 days but note that the crispiness will start to diminish as time passes.

Freezing

While you can freeze cooked potatoes, these crispy beauties don’t always reheat with the same texture after freezing. It’s best to freeze only if necessary, and when you do, spread them out on a tray before freezing to avoid clumping together.

Reheating

To bring back some crunch, reheat your leftover Extra Crispy Oven-Roasted Potatoes Recipe in a hot oven at 200°C (390°F) for 10–15 minutes or until heated through and crisp again. Avoid microwaving if you want to keep that delightful exterior texture.

FAQs

Can I use sweet potatoes for this recipe?

Sweet potatoes can be roasted with this method, but they behave differently due to their higher sugar content and moisture. They might brown too fast or become a bit softer, so reduce the roasting time slightly and keep an eye on them for the best results.

Why do we add baking soda to the boiling water?

The baking soda raises the pH level of the water, which helps break down the potato skins, creating a rougher surface that crisps up beautifully in the oven. It’s the key step for that extra crispy texture.

Can I skip the rosemary and garlic?

Absolutely! The rosemary and garlic add wonderful fragrance and subtle flavor but are completely optional. The potatoes themselves are delicious on their own with just olive oil and salt.

What type of potatoes works best?

Starchy potatoes like Russets or Maris Piper are perfect because they become fluffy inside and crisp outside. Waxy potatoes tend to stay firmer but won’t get quite as crispy.

How do I get the potatoes to cook evenly?

Make sure your potatoes are cut to relatively equal sizes and toss them regularly during roasting. Also, spreading them out so they’re not overcrowded helps each piece crisp evenly rather than steaming.

Final Thoughts

This Extra Crispy Oven-Roasted Potatoes Recipe is a foolproof way to elevate simple potatoes into an unforgettable side dish that everyone will rave about. With just a few smart techniques and everyday ingredients, you can create something effortlessly special that feels like a warm hug on a plate. Give it a try and watch your kitchen fill with irresistible aromas and your dinner plate disappear fast!

  • Total Time: 1 hour 30 minutes
  • Yield: 4 servings
  • Category: Side Dish
  • Method: Roasting
  • Cuisine: International

Ingredients

Potatoes

  • 1 kg potatoes (approximately 8 medium potatoes)
  • ¼ tsp baking soda (bicarbonate of soda)

Roasting

  • ⅓ cup olive oil
  • 4 sprigs fresh rosemary (optional)
  • 4 unpeeled garlic cloves, flattened slightly (optional)
  • Salt to taste

Instructions

  1. Preheat the oven: Set your oven to 210°C (410°F) and allow it to fully preheat while preparing the potatoes.
  2. Boil water with baking soda: Bring a large pot of water to a boil, then add ¼ teaspoon of baking soda, which will cause a slight fizzing, aiding in crispy potato texture.
  3. Prepare the potatoes: Peel the potatoes carefully while the water heats up, then carefully place them into the boiling water.
  4. Cook the potatoes: Boil the potatoes for about 20 minutes or until they become very soft when poked with a fork, ensuring they're cooked through.
  5. Heat the oil: With about 10 minutes remaining on the potato cooking time, pour ⅓ cup olive oil into a metal roasting tin and place it into the oven to heat thoroughly.
  6. Rough up the potatoes: Drain the cooked potatoes well and return them to the pot. Gently toss or shake them to roughen the surfaces; some breakage is fine as it helps achieve crispiness.
  7. Coat potatoes with hot oil: Carefully transfer the potatoes to the preheated roasting tin with the hot oil, turning to coat them evenly.
  8. Roast the potatoes: Bake in the oven for 1 to 1¼ hours, tossing the potatoes every 15 minutes to ensure even browning. If using, add rosemary sprigs and garlic cloves about 15 to 30 minutes before the end of roasting to infuse flavor.
  9. Finish and serve: Discard rosemary and garlic, season the roasted potatoes with salt to taste, and serve immediately while crispy and hot.

Notes

  • Using baking soda in the boiling water increases alkalinity, which helps break down the potato surfaces for better crisping.
  • The optional rosemary and garlic add aromatic flavor but can be omitted if preferred.
  • Use a metal roasting tin to ensure even heat distribution and better crisping.
  • Turning the potatoes regularly during roasting avoids them sticking and promotes uniform crispiness.
