Salt potatoes are a simple, rustic side dish made by boiling small, waxy potatoes in a heavily salted water bath until tender, then finishing with melted butter and fresh herbs. Originating from the salt-producing region of Syracuse, New York, they are traditionally served as a summer staple at cookouts and clambakes. This guide walks you through making them from scratch, ensuring creamy, perfectly seasoned potatoes every time.
What You’ll Need
- 2 lb (900 g) small waxy potatoes (such as baby Yukon Gold, red bliss, or fingerlings), scrubbed
- 1 cup (300 g) coarse salt (kosher or sea salt; do not use iodized table salt)
- 8 cups (1.9 L) water
- 4 tbsp (56 g) unsalted butter, melted
- 2 tbsp chopped fresh parsley or chives (optional)
- Flaky sea salt for finishing (optional)
Step-by-Step
- Prep the potatoes: Scrub the potatoes thoroughly under cold running water to remove any dirt. Do not peel them; the skins help hold the potatoes together and add texture.
- Make the brine: In a large pot (at least 5 quarts / 4.7 L), combine the water and coarse salt. Stir until most of the salt dissolves. The water should taste very salty, like seawater.
- Add the potatoes: Place the potatoes in the pot. The water should cover them by at least 1 inch (2.5 cm). If not, add more water.
- Bring to a boil: Set the pot over high heat and bring to a rolling boil. Do not cover the pot—this allows steam to escape and prevents the water from boiling over.
- Boil until tender: Reduce the heat to medium-high to maintain a steady boil. Cook for 15–25 minutes, depending on the size of your potatoes. Test doneness by piercing a potato with a thin knife or skewer—it should slide in with no resistance. Be careful not to overcook; you want them tender but not falling apart.
- Drain and steam dry: Drain the potatoes in a colander. Let them sit for 2–3 minutes to allow excess moisture to evaporate. This helps the butter adhere better.
- Finish with butter: Transfer the hot potatoes to a serving bowl. Pour the melted butter over them and toss gently to coat. Sprinkle with fresh herbs and flaky sea salt if desired.
- Serve immediately: Salt potatoes are best enjoyed warm, right after cooking. They can be held briefly in a low oven (200°F / 95°C) for up to 30 minutes, but they are at their peak when fresh.
Common Mistakes
- Using the wrong potatoes: Russets or other floury potatoes will break apart and become mushy. Stick to waxy or all-purpose varieties.
- Skimping on salt: The salt in the water is what seasons the potatoes from the inside out. Using less than 1 cup (300 g) per 8 cups (1.9 L) of water will result in bland potatoes.
- Overcooking: Boiling too long makes the potatoes waterlogged and they can split. Check frequently after 15 minutes.
- Not draining well: Leaving too much water on the potatoes dilutes the butter and makes the dish watery.
Tips
- Keep the skins on: The skin helps the potato hold its shape and provides a nice contrast in texture.
- Use a large pot: Crowding the potatoes can cause uneven cooking. Give them room to bob freely.
- Add aromatics (optional): For extra flavor, add a few sprigs of fresh thyme, a bay leaf, or a clove of garlic to the boiling water. This is not traditional, but it’s a tasty variation.
- Double the batch: Salt potatoes are great for parties. Just scale up the recipe, keeping the same salt-to-water ratio.
- Make ahead: You can boil the potatoes a few hours ahead, then reheat them in a skillet with a little butter or in the microwave before serving.
Troubleshooting
- Potatoes are too salty: If you accidentally used too much salt, the potatoes may be overly salty. To fix, rinse the drained potatoes with hot water quickly, then toss with unsalted butter. The butter will help balance the saltiness.
- Potatoes are bland: This usually happens when you didn’t use enough salt in the water. To rescue, sprinkle flaky sea salt over the finished potatoes and toss with extra butter.
- Potatoes are falling apart: They were overcooked. For next time, start checking at 12 minutes and use a fork to test. If they are already broken, you can mash them into a rustic potato salad or use them as a base for a soup.
- Water boiled over: This happens when the heat is too high or the pot is too small. Use a larger pot and keep the heat at a medium boil, not a violent one.
- Potatoes are undercooked: Return them to the pot with a little hot water and continue boiling for another 5 minutes, then check again.
Frequently Asked Questions
Can I use table salt instead of coarse salt?
Yes, but use half the amount—table salt is much denser. However, coarse salt dissolves more slowly and is less likely to make the potatoes taste harshly salty.
Do I need to peel the potatoes?
No, the skin is essential to the dish. It keeps the potato intact and adds texture.
How long do salt potatoes last in the fridge?
Cooked salt potatoes can be stored in an airtight container in the refrigerator for up to 4 days. Reheat gently in the microwave or in a skillet with a little butter.
Can I use sweet potatoes?
You can, but they will have a different texture and flavor. Use waxy sweet potatoes and reduce the cooking time slightly.
What can I serve with salt potatoes?
They pair well with grilled meats, fish, or as part of a seafood boil. They’re also great with a simple green salad.
Is it safe to reuse the salted water?
Yes, you can reuse the brine for another batch of potatoes, but it will be slightly less salty. Add a little more salt if needed.
