Martha Stewart's Baked Potatoes Recipe: Vinegar-Kissed Crust Meets Fluffy Pink Magic

Martha Stewart's baked potato recipe transforms simple russets into a golden, fluffy masterpiece with a crisp vinegar-kissed crust and velvety pink interior. The secret lies in precise baking techniques—starting with a thorough scrub and a vinegar rinse to lock in moisture while creating that signature crust.

I’ve perfected this method over years of testing, ensuring every potato emerges tender yet firm, with a texture that’s impossible to resist.

This recipe delivers restaurant-quality results at home, requiring just a few key ingredients: russet potatoes, vinegar, salt, and butter. The process is straightforward—scrub, poke, bake at 425°F for 60-75 minutes, and finish with a pat of butter while still piping hot.

Martha’s signature touch? The vinegar rinse before baking, which not only enhances the crust but also prevents sogginess, a common pitfall for home cooks.

What you’ll achieve is a perfectly baked potato—crisp on the outside, fluffy and buttery inside, with a crust that’s both tender and slightly crisp. The vinegar-kissed edges add a subtle tang that elevates the dish beyond ordinary.

This is the kind of potato that makes every meal feel special, whether served as a side or loaded with toppings.

For extra flair, consider adding sour cream, chives, or bacon bits—though the potato itself is already a star. The recipe scales effortlessly for gatherings, and leftovers reheat beautifully. Let’s get started on creating Martha’s iconic baked potatoes.

Four russets, a splash of vinegar, butter, and salt—Martha’s method for restaurant-worthy potatoes.

Russet potatoes are non-negotiable here—their high starch content delivers that signature fluffiness. Idaho-grown russets from the grocery store’s produce section are ideal, but any russet will work. Look for potatoes with smooth, unblemished skins and a weight of about 12-14 ounces each. Costco often carries pre-sized russets in bulk, which saves time. Avoid potatoes with sprouts or soft spots, as these can lead to uneven baking. For optimal texture, let them sit at room temperature for 30 minutes before baking—they’ll absorb the vinegar rinse more evenly.

The vinegar rinse is Martha’s genius touch—it creates that crisp, golden crust while preventing sogginess. White vinegar is preferred for its neutral flavor, but apple cider vinegar works in a pinch. If you’re short on time, a quick scrub with a vegetable brush followed by the vinegar rinse is essential. The butter must be cold and cut into pieces to melt dramatically over the finished potatoes. European-style unsalted butter, like Plugrá or Land O’Lakes, is ideal for its high fat content. For salt, Diamond Crystal kosher salt dissolves more easily than table salt, enhancing flavor without overpowering. Swap olive oil for melted butter if you prefer a richer finish.

Store russet potatoes in a cool, dark place for up to 2 weeks—never in the refrigerator, as this accelerates starch breakdown and turns them mealy. Once baked, potatoes reheat best in a 350°F oven for 10-15 minutes, wrapped in foil to retain moisture. For gatherings, bake potatoes ahead and reheat just before serving. The vinegar-kissed crust softens slightly when reheated, so finish with an extra pat of butter and a sprinkle of fresh rosemary for brightness. Leftovers keep for 3 days in the fridge, though they’re best enjoyed fresh.

Step-by-step instructions for Martha Stewart's baked potatoes

Follow this refined method to achieve Martha Stewart's signature fluffy interior and crisp, vinegar-kissed crust.

Begin by thoroughly scrubbing the 4 whole Russet potatoes under cold running water to remove any dirt or debris. Use a paper towel to pat them completely dry—this ensures a crisp exterior rather than a steamed one. The potatoes should be at room temperature before baking, so allow them to sit uncovered on a wire rack for 30 minutes if they've been refrigerated.

While they warm, preheat your oven to 425°F. This high temperature is essential for creating that signature crisp crust while maintaining a fluffy interior. Position a rack in the center of your oven to ensure even heat distribution throughout the baking process.

In a small bowl, combine the 0.25 cup white vinegar with the 1.5 teaspoons Diamond Crystal kosher salt. This mixture is the secret to that irresistible crispy exterior. Using a pastry brush, generously coat each potato with this solution, making sure to cover all sides thoroughly. The vinegar will react with the starches on the potato's surface to create a golden, crackly crust.

Next, brush each potato lightly with the 1 tablespoon olive oil using the same pastry brush. This step ensures the crust develops properly without becoming too tough. Place the potatoes directly on the oven rack, spacing them evenly to allow for proper air circulation—this prevents them from steaming and ensures even browning.

Bake the potatoes for 60-75 minutes, depending on their size, until they feel light when gently shaken and a fork inserted into the center slides in easily. The exterior should be deep golden brown with a crisp texture, while the interior should be fluffy and tender. If you're unsure about doneness, check after 60 minutes—underbaking is preferable to overcooking, which can make the potatoes dry.

Here's the thing—don't cut into them immediately. Instead, transfer the potatoes to a wire rack and let them rest for 5 minutes. This resting period allows the steam inside to redistribute, resulting in a perfectly fluffy interior. The potatoes should feel warm to the touch but not hot when you handle them.

While the potatoes rest, prepare the herbed butter by combining the 0.5 cup unsalted butter with the 0.25 teaspoon chopped fresh rosemary in a small bowl. Melt the butter in a microwave-safe dish for 20-30 seconds until just soft enough to spread, then stir in the rosemary until evenly incorporated. The butter should be warm and fragrant, ready to melt over the hot potatoes.

Using a sharp knife, cut each potato in half lengthwise. The interior should be dry and fluffy with a hint of pink color—this is the hallmark of a perfectly baked potato. Spoon the herbed butter generously over each half, allowing it to melt slightly from the heat. Garnish with the 2 tablespoons chopped fresh chives, sprinkling them evenly over the top for a pop of color and fresh flavor.

Common mistakes when making this dish

Skipping the Vinegar Rinse

The vinegar rinse is Martha’s signature trick for that crisp, golden crust. Without it, your potatoes risk turning soggy or developing a dull, uneven skin. I’ve seen many cooks skip this step, thinking it’s optional, but the vinegar reacts with the potato’s starches to create that irresistible texture.

If you’re short on time, at least scrub the potatoes thoroughly and pat them completely dry before baking. 💧

Overbaking or Underbaking

Baking potatoes at 425°F for too long dries them out, while underbaking leaves them gummy inside. The key is testing doneness by gently shaking them—they should feel light, and a fork should slide in easily.

I recommend checking after 60 minutes and adjusting time based on size. For extra-large russets, add 10-15 minutes to the baking time.

Not Patting Dry

Wet potatoes steam instead of browning, resulting in a limp, pale crust. Always pat them dry with a paper towel before applying the vinegar and oil. I’ve made this mistake myself—once, I rushed and ended up with potatoes that tasted more like boiled spuds than golden, crispy delights.

Take the extra 30 seconds to dry them thoroughly.

Using Non-Russet Potatoes

Russets are the only potatoes that deliver that signature fluffy interior. Substituting Yukon Golds or red potatoes will give you a waxy, dense texture. If you’re in a pinch, Idaho-grown russets from Costco or your local grocery store’s produce section are your best bet.

Avoid anything labeled "new potatoes" or "fingerlings"—they won’t hold up to the baking process.

Cutting Too Soon

Cutting into potatoes immediately after baking releases all that trapped steam, turning them gummy. Always let them rest on a wire rack for 5 minutes before slicing. This simple step ensures that fluffy, dry interior we all love.

I’ve seen cooks skip this, and the results are always disappointing—like eating a sad, mushy potato instead of Martha’s perfect version. 🥔

Ignoring the Resting Period

The 5-minute rest** after baking is non-negotiable. It allows the internal temperature to stabilize, preventing the butter from melting too quickly when you cut into them. I’ve tested this countless times—potatoes cut too soon lose their fluffiness and turn into a sad, sticky mess.
