State fair salt potatoes are a beloved Midwestern classic, especially famous in Minnesota, where baby potatoes are boiled in heavily salted water until tender, then roasted or fried until the skins turn shatteringly crisp and the insides stay creamy. The high salt concentration in the cooking water seasons the potatoes all the way through, so every bite is briny, buttery, and utterly addictive. This recipe delivers that same fairground magic at home with simple ingredients and a few key techniques.
Ingredients
- 2 lb (900 g) baby potatoes (such as Yukon Gold or red bliss), scrubbed
- 1/2 cup (120 g) kosher salt, plus more for finishing
- 4 cups (960 ml) water
- 3 tbsp (45 ml) olive oil or melted butter
- 2 tbsp (30 g) unsalted butter, melted
- 1 tsp (5 g) garlic powder
- 1/2 tsp (1 g) smoked paprika (optional)
- Freshly ground black pepper, to taste
- Flaky sea salt, for sprinkling
- 2 tbsp (8 g) chopped fresh parsley or chives, for garnish
Instructions
- Preheat your oven to 425°F (220°C). If you have a wire rack, place it over a baking sheet; otherwise, line the sheet with parchment paper.
- In a large pot, combine the water and kosher salt. Bring to a rolling boil over high heat. The salt should dissolve completely, creating a super-saline brine.
- Add the baby potatoes to the boiling brine. Boil for 12–15 minutes, or until a knife pierces a potato with just slight resistance—they should be tender but not falling apart. Drain well and let them steam dry in the colander for 2–3 minutes.
- Transfer the hot potatoes to the prepared baking sheet (or rack). Use the bottom of a heavy glass or a potato masher to gently press down on each potato until it splits and flattens to about 1/2-inch thick. Don’t press too hard—you want them to stay in one piece.
- In a small bowl, mix the olive oil (or melted butter), garlic powder, smoked paprika (if using), and a few grinds of black pepper. Brush this mixture generously over the tops of the flattened potatoes.
- Roast for 20–25 minutes, until the edges are deeply golden and crispy. If you like them extra crunchy, flip them halfway through and brush with more oil.
- Remove from the oven and immediately drizzle with the melted butter. Sprinkle with flaky sea salt and fresh parsley or chives. Serve hot.
Tips
- Don’t skip the brine: The high salt concentration (about 1/2 cup per 4 cups water) is what seasons the potatoes internally. Regular salted water won’t give the same flavor punch.
- Dry the potatoes well: After draining, let them sit in the colander to release steam. Excess moisture will make them steam instead of crisp in the oven.
- Use a wire rack: If you have one, roasting on a rack allows hot air to circulate underneath, making the bottoms crispy too. If not, parchment paper works, but flip them halfway.
- Substitutions: No baby potatoes? Use small Yukon Gold or red potatoes cut into 1-inch chunks. For a milder brine, use 1/4 cup salt, but the flavor will be less intense.
Serving Suggestions
Serve these salt potatoes as a side dish for grilled burgers, hot dogs, or BBQ chicken. They also shine as a snack with a side of sour cream and chive dip, or a simple aioli. For a fair-inspired meal, pair them with corn dogs and a cold lemonade.
Variations
- Cheesy: After roasting, sprinkle with 1/2 cup (50 g) shredded cheddar or Parmesan and return to the oven for 2 minutes until melted.
- Spicy: Add 1/2 tsp cayenne pepper or a drizzle of hot sauce to the oil mixture before roasting.
- Herb butter: Swap the melted butter for a compound butter made with minced garlic, rosemary, and thyme.
- Air fryer: Boil the potatoes as directed, then air-fry at 400°F (200°C) for 10–12 minutes, shaking halfway.
Storage and Reheating
Store leftover potatoes in an airtight container in the refrigerator for up to 4 days. To reheat, place them on a baking sheet and warm in a 400°F (200°C) oven for 5–7 minutes until crisp. You can also reheat in an air fryer at 375°F (190°C) for 3–4 minutes. Avoid microwaving, as it makes the skins soggy.
Frequently Asked Questions
Can I use less salt? Yes, but the potatoes won’t be as flavorful. The salt is what gives them their signature taste. If you’re watching sodium, reduce to 1/4 cup (60 g) and add a little extra salt after roasting.
Why are my potatoes not crispy? The most common reasons are not drying them well after boiling, overcrowding the baking sheet, or not roasting long enough. Make sure they’re in a single layer with space between them.
Can I make these ahead of time? You can boil and flatten the potatoes up to 2 hours ahead, then cover and refrigerate. When ready to serve, brush with oil and roast as directed, adding 5 minutes to the cooking time.
What type of potatoes work best? Waxy potatoes like Yukon Gold or red bliss hold their shape during boiling and flattening. Russets will fall apart more easily.
Can I skip the boiling and just roast? No, the boiling is essential for infusing the salt and pre-cooking the potatoes. Roasting raw potatoes won’t give the same creamy interior.
How do I store leftover brine? The salted water can be cooled and refrigerated for up to 1 week. Reuse it for another batch of potatoes or for boiling corn on the cob.
