Salt potatoes are a beloved side dish from the Syracuse region of upstate New York, where small, waxy new potatoes are boiled in a heavily salted water bath until tender, then tossed with melted butter. The high salt concentration raises the boiling point of the water, which cooks the potatoes evenly and seasons them from the inside out, resulting in a creamy, buttery texture and a delicate salty crust. This recipe recreates the authentic dish with a simple method that works every time.
Ingredients
- 2 lb (900 g) small new potatoes (about 1–1.5 inches in diameter), scrubbed
- 1 cup (300 g) fine sea salt (or kosher salt, see Tips)
- 8 cups (1.9 L) water
- 1/2 cup (1 stick / 113 g) unsalted butter, melted
- Flaky sea salt, for finishing (optional)
- Fresh parsley, chopped (optional, for garnish)
Instructions
- Place the scrubbed potatoes in a large pot. Add the 1 cup (300 g) salt and the 8 cups (1.9 L) water. The water should cover the potatoes by at least 1 inch; add more water if needed.
- Bring the water to a rolling boil over high heat. Reduce the heat to medium-high and maintain a vigorous simmer (not a full boil) for about 20–25 minutes, or until the potatoes are fork-tender. Start checking at 15 minutes; the exact time depends on potato size.
- Drain the potatoes in a colander. Let them steam dry for 2–3 minutes, which helps the skins tighten and the salt crust form.
- Transfer the hot potatoes to a serving bowl. Pour the melted butter over them and toss gently to coat. Sprinkle with flaky sea salt and parsley if using. Serve hot.
Tips
- Salt type: Use fine salt for the boiling water—it dissolves quickly and evenly. If using kosher salt, use 1.5 cups (450 g) because its crystals are larger and less dense. Do not use iodized table salt with anti-caking agents, as they can leave a slight off-flavor.
- Potato size: Keep the potatoes whole and uniform in size so they cook evenly. If you only have larger potatoes, cut them into 1.5-inch chunks—they will still absorb salt well.
- Don’t skip the steam-dry: Letting the potatoes sit in the colander for a few minutes after draining allows the salt water to evaporate, leaving a thin, salty crust that is the signature of this dish.
- Butter quality: Use real unsalted butter—the salt from the potatoes will season the butter as it melts. If using salted butter, reduce the finishing salt.
Serving Suggestions
Serve salt potatoes as a side for grilled steaks, roasted chicken, or fried fish. They are also excellent with a simple green salad and a glass of white wine. For a classic Central New York meal, pair them with a hot dog or sausage and a cold beer.
Variations
- Herb butter: Stir 2 tablespoons of chopped fresh dill, chives, or parsley into the melted butter before tossing.
- Garlic salt potatoes: Add 2 smashed garlic cloves to the boiling water and finish with a sprinkle of garlic powder.
- Spicy version: Add 1 teaspoon of red pepper flakes to the butter, or toss the finished potatoes with a pinch of cayenne.
- Cheesy: After tossing in butter, sprinkle with 1/2 cup (50 g) grated Parmesan cheese and serve immediately.
Storage and Reheating
Store leftover salt potatoes in an airtight container in the refrigerator for up to 4 days. To reheat, place them in a microwave-safe dish with a splash of water and heat in 30-second bursts until hot, or spread them on a baking sheet and warm in a 350°F (175°C) oven for 10 minutes. The skins may soften, but the flavor remains. Do not freeze—the texture will become mushy.
Frequently Asked Questions
Why do salt potatoes need so much salt? The high salt concentration (about 1 cup per 8 cups water) raises the boiling point of the water, which helps the potatoes cook more evenly and prevents them from becoming waterlogged. It also seasons the potatoes from the inside out, giving them a unique flavor that can’t be achieved by salting after cooking.
Can I use regular potatoes instead of new potatoes? Yes, but the texture will be different. New potatoes are waxy and hold their shape well. If using russets or other starchy potatoes, cut them into 1.5-inch chunks and watch them carefully—they may fall apart if overcooked.
Is the salt water reusable? No, the salt water is discarded. It contains starch and potato residue, so it is not suitable for reuse. Do not try to save it for soups or stocks.
Can I make this in advance? Salt potatoes are best served immediately after cooking. If you need to make them ahead, cook, drain, and keep them warm in a slow cooker on low for up to 2 hours, but the skins will soften.
Why are my potatoes not salty enough? If you used kosher salt without adjusting the quantity, or if your potatoes are larger than 1.5 inches, they may not absorb enough salt. Make sure to use the correct salt amount and keep the potatoes whole and small.
What if I don’t have fine sea salt? You can use pickling salt (which is pure sodium chloride) or a fine-grained kosher salt like Diamond Crystal. For table salt, reduce the amount to 3/4 cup (225 g) because it is denser and more concentrated.
