Salt-encrusted baked potatoes are a simple, dramatic way to get the perfect baked potato: a tender, fluffy interior and a seasoned, slightly crisp skin. The salt crust draws out moisture and seasons the skin deeply, while the potato steams inside its own skin for an incredibly creamy texture. This method is foolproof and works with any variety of potato, making it a great side dish for weeknight dinners or special roasts.
Ingredients
- 4 medium russet or Idaho potatoes (about 8 oz / 225 g each), scrubbed and dried
- 1 ½ cups (300 g) coarse kosher salt or sea salt (do not use fine table salt)
- ½ cup (120 ml) water
- 2 tablespoons (30 ml) olive oil or melted butter, for brushing (optional)
- Flaky sea salt, for finishing (optional)
Instructions
- Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or aluminum foil for easy cleanup.
- In a medium bowl, mix the coarse salt and water together until the salt is evenly moistened—it should look like wet sand. If it seems too dry, add another tablespoon of water; if too wet, add a little more salt.
- Prick each potato 3–4 times with a fork. This allows steam to escape and prevents the potatoes from bursting during baking.
- Spread about half of the wet salt mixture onto the prepared baking sheet in a rough rectangle large enough to hold the potatoes.
- Place the potatoes on top of the salt bed, leaving a little space between each one. Pack the remaining salt mixture over and around the potatoes, covering them completely. Press gently so the salt adheres.
- Bake for 1 hour to 1 hour 15 minutes, until the potatoes are tender when pierced with a skewer through the salt crust. The salt will form a hard, crackled shell.
- Remove the baking sheet from the oven and let the potatoes rest for 5 minutes. Then, gently crack the salt crust with the back of a spoon or a knife. Brush off any excess salt with a pastry brush or your hands.
- If you like, brush the potato skins with olive oil or melted butter and sprinkle with flaky sea salt. Serve hot, cut open, and fluff the insides with a fork.
Tips
- Choose the right potato: Russets or other starchy potatoes are best for baking because they yield a light, fluffy interior. Waxy potatoes like red or Yukon Gold will be denser and creamier, but still delicious.
- Don’t use fine salt: Table salt is too fine and will make the crust overly salty and hard to brush off. Coarse kosher salt or sea salt is essential—it creates a crust that cracks off easily and doesn’t over-salt the potato.
- Adjust the salt amount: The salt is not meant to be eaten in large chunks; it’s a seasoning and baking medium. If you’re watching sodium, you can reduce the salt to 1 cup (200 g) and still get a good crust, though the potatoes may be slightly less seasoned.
- Check for doneness: Baking times vary with potato size and oven accuracy. If you’re unsure, insert an instant-read thermometer into the center of a potato through the crust—it should read 205°F (96°C) for a perfectly fluffy texture.
Serving Suggestions
Serve these salt-encrusted potatoes as a side to grilled steak, roast chicken, or pan-seared fish. They’re also fantastic with a simple pat of butter, a dollop of sour cream, and fresh chives. For a heartier meal, top with chili, shredded cheese, or broccoli and cheddar sauce.
Variations
- Herb-Infused Salt Crust: Mix 2 teaspoons of dried rosemary, thyme, or oregano into the wet salt mixture before packing. This will subtly perfume the potato skins.
- Spicy Salt Crust: Add 1 teaspoon of smoked paprika or chipotle powder to the salt mixture for a smoky, spicy kick.
- Garlic Butter Finish: Instead of olive oil, brush the finished potatoes with melted butter mixed with minced garlic and parsley.
- Sweet Potatoes: This method works beautifully with sweet potatoes, though they may bake a little faster—check at the 50-minute mark.
Storage and Reheating
Store any leftover baked potatoes (without the salt crust) in an airtight container in the refrigerator for up to 4 days. To reheat, place them in a 350°F (175°C) oven for 10–15 minutes, or until heated through. You can also microwave them for 2–3 minutes, but the skin will be less crisp. The salt crust is best used fresh; it will become soggy if stored.
Frequently Asked Questions
Can I use fine table salt instead of coarse salt? No, fine salt will make the crust too salty and difficult to remove. Coarse kosher salt or sea salt is essential for a crust that cracks off cleanly.
Do I need to poke holes in the potatoes? Yes, always prick the potatoes with a fork before baking. This allows steam to escape and prevents them from bursting in the oven.
Can I use this method for sweet potatoes? Absolutely. Sweet potatoes work great, but they may cook a little faster, so start checking at 50 minutes.
What if my salt crust doesn’t harden? If the salt mixture is too wet, it won’t form a hard crust. Make sure you use just enough water to moisten the salt—it should look like wet sand, not a slurry. Also, make sure the potatoes are completely covered.
Can I reuse the salt? No, the salt absorbs moisture and flavor from the potatoes, so it’s best to discard it after baking.
How do I know the potatoes are done? The most reliable way is to insert a skewer or knife through the crust into the center of a potato. It should slide in easily. An instant-read thermometer should read 205°F (96°C) for a fluffy texture.
