Salt and Vinegar Fingerling Potatoes

This Salt and Vinegar Fingerling Potatoes recipe gives me crispy, tangy, and savory potatoes that remind me of the classic potato chip flavor but in a warm, hearty side dish. I love how simple it is to prepare and how the vinegar adds a bold punch that pairs perfectly with the crispy texture.

Why You’ll Love This Recipe

I like this recipe because it transforms basic fingerling potatoes into something really special. The vinegar soak infuses the potatoes with a tangy brightness, while roasting makes them crispy on the outside and tender on the inside. It’s an easy dish to serve with grilled meats, roasted chicken, or even as a snack on its own. I also appreciate that the ingredients are pantry staples and that the whole recipe doesn’t take much time at all.

Ingredients

(Note: All ingredient amounts are listed in the recipe card below.)

1 pound (454 grams) fingerling potatoes, sliced lengthwise to 1/4-inch thickness
2 cups distilled white vinegar, see note 2
1 tablespoon plus 1 teaspoon kosher salt
2 tablespoons olive oil
¼ teaspoon freshly ground black pepper

Directions

1. I start by placing the sliced fingerling potatoes in a saucepan and covering them with the vinegar. I bring it to a boil and let it simmer for about 5 minutes to infuse the flavor.
2. I drain the potatoes and let them dry slightly so they crisp better in the oven.
3. I preheat the oven to 425°F (220°C) and line a baking sheet with parchment paper.
4. I toss the potatoes with olive oil, salt, and pepper, making sure each piece is well coated.
5. I spread the potatoes in a single layer on the baking sheet.
6. I roast for 25–30 minutes, flipping once halfway through, until the edges are golden brown and crisp.
7. I let them cool slightly before serving, so the flavor really shines through.

Servings and Timing

This recipe serves 4 people as a side dish. The total time is about 45 minutes, with 10 minutes of prep, 5 minutes of simmering, and around 30 minutes of roasting.

Variations

I sometimes swap the white vinegar with apple cider vinegar for a slightly sweeter tang. For a spicy kick, I add a pinch of cayenne or smoked paprika to the seasoning mix.

Storage/Reheating

I store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, I spread them out on a baking sheet and warm them in a 375°F (190°C) oven for about 10 minutes to bring back their crispiness. I avoid microwaving since it makes them soggy.

FAQs

Can I use another type of potato?

Yes, I can use baby potatoes or Yukon golds, but fingerlings hold their shape and crispiness best.

Do I have to boil the potatoes in vinegar?

I like doing this step because it helps the vinegar flavor soak in, but I can also just toss them in vinegar after roasting if I want a milder taste.

Can I use balsamic vinegar?

I don’t recommend it because it’s too sweet and dark; white vinegar or apple cider vinegar works better.

How do I make them extra crispy?

I make sure the potatoes are well dried after boiling and avoid crowding the baking sheet.

Can I air fry instead of roasting?

Yes, I air fry them at 400°F (200°C) for about 15–18 minutes, shaking halfway through.

Do I need to peel the fingerling potatoes?

No, I leave the skins on since they get crispy and add texture.

Can I make these ahead of time?

I can parboil the potatoes in vinegar ahead of time and roast them later when I’m ready to serve.

What can I serve with salt and vinegar potatoes?

I like serving them with grilled fish, roasted chicken, burgers, or even just a simple salad.

Can I use flavored vinegars?

Yes, but I keep in mind that some may add sweetness or extra flavors that change the dish.

How do I keep them from sticking to the pan?

I line the baking sheet with parchment paper or lightly grease it with oil before roasting.

Conclusion

These Salt and Vinegar Fingerling Potatoes give me the perfect mix of tangy and crispy in every bite. I enjoy how simple they are to prepare and how versatile they can be for meals. Whether I serve them with dinner or enjoy them as a snack, they always deliver bold flavor and satisfying crunch.
