Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

2 pounds Yukon Gold potatoes, peeled and cut into chunks
1 tablespoon baking soda
1 tablespoon salt, plus extra for seasoning
4 tablespoons olive oil
3 cloves garlic, minced
1 teaspoon black pepper
1 teaspoon paprika
1 teaspoon dried rosemary
1 teaspoon dried thyme
2 tablespoons chopped fresh parsley

Directions

Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper or lightly grease it with oil.
Bring a large pot of water to a boil. Add the salt and baking soda to the water, then carefully add the potato chunks.
Boil the potatoes for about 10 minutes or until the edges begin to soften slightly. The baking soda helps create a rough outer layer that becomes crispy during roasting.
Drain the potatoes well and return them to the pot. Gently shake the pot for a few seconds to rough up the potato surfaces. This step is important for achieving maximum crispiness.
Add olive oil, garlic, black pepper, paprika, rosemary, and thyme. Toss carefully until all the potatoes are evenly coated.
Spread the potatoes in a single layer on the prepared baking sheet. Leave a little space between the pieces so they roast instead of steam.
Roast for 40 to 45 minutes, flipping halfway through cooking. Continue roasting until the potatoes are deeply golden and crispy on all sides.
Remove from the oven and sprinkle with fresh parsley and extra salt if desired. Serve immediately while hot and crispy.

Servings and timing

This recipe makes about 6 servings.

Prep Time: 15 minutes
Cook Time: 45 minutes
Total Time: 1 hour

Variations

Add grated Parmesan cheese during the last 10 minutes of roasting for a cheesy finish.
Use sweet potatoes instead of Yukon Gold for a slightly sweeter flavor.
Sprinkle chili flakes or cayenne pepper for extra heat.
Replace rosemary and thyme with Italian seasoning for a different herb blend.
Add onion powder and garlic powder for stronger savory flavor.
Toss the finished potatoes with lemon zest for a fresh and bright taste.
Use duck fat or melted butter instead of olive oil for a richer texture.

Storage/Reheating

Store leftover potatoes in an airtight container in the refrigerator for up to 4 days.

To reheat, place the potatoes on a baking sheet and warm them in a 400°F oven for about 10 minutes. This helps restore their crispy texture. You can also reheat them in an air fryer for 5 to 7 minutes.

Avoid microwaving if possible, as it can make the potatoes soft instead of crispy.

You can freeze the roasted potatoes for up to 2 months. Reheat directly from frozen in the oven until heated through and crispy again.

FAQs

Why does baking soda make potatoes crispier?

Baking soda raises the pH level of the water, which helps break down the potato surface and creates a rough texture that crisps beautifully in the oven.

What type of potatoes work best for this recipe?

Yukon Gold potatoes are ideal because they have a creamy center and crisp nicely. Russet potatoes also work very well.

Do I have to peel the potatoes?

No, you can leave the skin on for extra texture and flavor if you prefer.

Can I make these potatoes in an air fryer?

Yes, cook them in batches at 400°F for about 18 to 20 minutes, shaking halfway through.

Why are my potatoes not crispy?

Overcrowding the pan can trap steam and prevent crispiness. Spread the potatoes out evenly with space between them.

Can I prepare the potatoes ahead of time?

Yes, you can boil and season the potatoes a few hours ahead, then roast them when ready to serve.

Is baking soda safe to cook with?

Yes, baking soda is completely safe in small cooking amounts and is commonly used in many recipes.

Can I use other seasonings?

Absolutely. Garlic powder, smoked paprika, cumin, oregano, or curry powder all work well.

How do I keep roasted potatoes crispy longer?

Serve them immediately after roasting and avoid covering them tightly, which can trap steam.

Can I make this recipe vegan?

Yes, the recipe is naturally vegan when made with olive oil.
