Martha Stewart's Smashed Potatoes Recipe: Crispy Vinegar-Kissed Crowns Over Creamy Hearts

Martha Stewart's smashed potatoes recipe delivers the perfect balance of crispy vinegar-kissed crowns and creamy, buttery centers—this timeless side transforms humble potatoes into a showstopper.

The secret lies in the technique: boiling potatoes until tender, gently smashing them to create those signature crowns, then finishing with a tangy vinegar-butter wash that creates irresistible texture. I've perfected this method over years of testing, ensuring every bite delivers that satisfying contrast between crispy edges and velvety insides.

What makes these potatoes truly special is how the simple act of smashing transforms ordinary potatoes into something restaurant-worthy. Using a potato ricer or fork to create those characteristic crowns is crucial—it's what gives them their signature look and texture.

The vinegar-butter finishing touch adds a bright, tangy element that cuts through richer dishes while enhancing the natural potato flavor. This recipe delivers professional-quality results in just 30 minutes of active time, with minimal effort but maximum impact.

By the time these potatoes emerge from the oven, you'll have golden, crispy crowns with tender, creamy centers that practically melt in your mouth. The vinegar-kissed edges add a delightful tang that balances the richness of the butter and cream inside.

This is the kind of side dish that elevates any meal from ordinary to extraordinary—whether you're serving it alongside roasted chicken, steak, or even a simple grilled fish. The aroma alone will have everyone at the table asking for seconds.

The best part? This recipe is incredibly versatile. You can customize it with additions like roasted garlic, truffle oil, or fresh herbs for extra depth of flavor. For extra crispiness, broil the potatoes for the final 2-3 minutes.

Serve immediately while the edges are still crispy and the centers remain creamy. Here's how to achieve Martha Stewart's signature smashed potatoes in your own kitchen.

Ingredients for martha stewart smashed potatoes

Four ingredients transform humble potatoes into Martha's signature crispy, creamy showstopper side.

The potatoes are everything here. Russets are your best bet—they’re starchy enough to hold their shape when smashed but creamy inside. Buy them fresh (the grocery store’s pre-bagged ones work fine), but avoid any with sprouts or soft spots. I usually grab mine from Whole Foods or the produce section at Trader Joe’s—their bins have the best quality. Medium-sized potatoes are ideal because they’re easy to handle and smash evenly. If you’re feeling fancy, you can roast the garlic cloves with olive oil and sea salt first for extra depth (worth the 10 minutes).

No white wine vinegar? Apple cider vinegar or lemon juice works just as well—it’s the tang that makes these shine. Short on butter? Use ghee or olive oil, but the butter’s richness is key for that creamy center. Fresh rosemary isn’t mandatory, but if you’ve got it, the aroma is next-level. Dried rosemary works at half the amount, but fresh is always better. The heavy cream can be swapped for half-and-half or whole milk if you’re watching fat, though the texture won’t be quite as luscious. And if you’re out of salt, soy sauce or Worcestershire can add umami depth in a pinch (use sparingly!).

These potatoes are best served immediately—crispy crowns turn soggy fast. But if you’re prepping ahead, boil the potatoes, cool them completely, then store in the fridge for up to 2 days. Reheat in a 350°F oven for 15-20 minutes until the edges are crispy again. For leftovers, the vinegar-butter wash can be reheated separately and drizzled back on top. The flavor actually improves the next day as the vinegar mellows and the butter melts into the potatoes. Pro tip: Broil for 2-3 minutes at the end if you want extra crispiness—just watch them like a hawk!

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

Here's how to achieve that perfect balance of crispy golden edges and creamy interiors—just like Martha makes.

Start by preheating your oven to 425°F. While it heats, scrub the 2 lb russet potatoes clean under cold water—no need to peel. Cut them into 1-inch thick slices (about 12-15 pieces total). This thickness ensures they'll smash evenly and cook through without falling apart.

Place the potato slices on a rimmed baking sheet lined with parchment paper. Arrange them in a single layer, slightly overlapping if needed. This setup prevents them from drying out and makes smashing easier later. Pat them dry with paper towels—moisture is the enemy of crispy edges.

Here's where the magic happens: using your hands, gently press down on each potato slice until they're about ½-inch thick. You want to flatten them without tearing—think of it like making little potato crowns. I press down firmly but evenly, working in the center first and then pressing outward toward the edges.

Season immediately with 1 tsp salt (save the remaining 0.5 tsp for later) and 0.25 tsp freshly ground black pepper. Drizzle lightly with 1 tbsp olive oil and toss gently to coat. The oil helps create that beautiful crispy crust while the vinegar we'll add later brings the tangy brightness. Transfer the baking sheet to the preheated oven.

Roast the potatoes for 25-30 minutes, flipping them halfway through, until they're golden brown on both sides and a fork slides in easily. You'll notice the edges start to crisp up while the centers remain tender—this is exactly what we want. If they brown too quickly, tent with foil to prevent burning.

While they roast, make the creamy topping: in a small saucepan, melt the 0.5 cup unsalted butter over low heat. Stir in the 2 tbsp white wine vinegar and 0.25 cup heavy cream, then remove from heat. Add the remaining 0.5 tsp salt and 0.25 tsp black pepper. The vinegar brightens the richness, creating that signature Martha Stewart tang.

Once the potatoes are golden and tender, remove them from the oven and immediately pour the warm butter-cream mixture evenly over the top. The residual heat from the potatoes will make the butter melt beautifully, creating that luscious sauce that pools underneath. Sprinkle with the 2 minced garlic cloves and 2 rosemary sprigs for aroma.

Return the potatoes to the oven for just 2-3 minutes to let the sauce melt and soak in. Watch closely—they'll finish cooking quickly. Serve immediately while the sauce is still warm and creamy. The contrast of crispy edges and tender, saucy centers makes these potatoes irresistible.

Flavor customization for this martha stewart smashed potatoes

Herb-Infused Variations

Swap the rosemary for fresh thyme or sage—both add earthy depth that pairs beautifully with the vinegar-butter finish. I like using 2 sprigs of thyme with 1 tsp minced shallots for a French bistro twist.

For a Mediterranean touch, add 1 tbsp chopped oregano and a pinch of red pepper flakes to the butter sauce before drizzling. 🌿

Garlic and Truffle Elevations

Roast 4 garlic cloves with 1 tbsp olive oil and ½ tsp salt at 400°F for 10 minutes until caramelized, then mash into the butter-cream mixture.

For luxury, stir in ½ tsp truffle oil (about ¼ tsp if using a stronger brand like La Tourangelle) and top with microgreens for a restaurant-worthy presentation. The truffle adds an umami richness that balances the vinegar's brightness.

Spicy Kick Options

Add ½ tsp smoked paprika or ¼ tsp cayenne pepper to the butter sauce for warmth. For a smoky-sweet contrast, mix 1 tsp honey with the vinegar before adding it to the butter.

I also love sprinkling crumbled chorizo (about 2 tbsp) over the top before the final broil—it adds a salty, spicy crunch that's irresistible. 🌶️

Cheesy Twists

Stir ¼ cup grated Gruyère or Parmesan into the butter-cream mixture while it's still warm. For a gooey surprise, place 1 oz goat cheese dollops on each potato before the final broil—they'll melt into creamy pools.

Sharp cheddar lovers can mix 2 tbsp shredded cheddar with the salt before seasoning the smashed potatoes. The cheese adds a salty, savory layer that complements the vinegar perfectly.

Citrus Zest Brightness

Finish with a burst of citrus by adding 1 tsp lemon zest to the butter sauce or sprinkling fresh lemon pepper (a mix of ½ tsp lemon zest and ½ tsp cracked black pepper) over the top.

For a tropical twist, swap the vinegar for 1 tbsp orange juice and add ½ tsp ground ginger to the butter mixture. The citrus cuts through the richness while adding a refreshing contrast.

Umami Boosters

Add depth with 1 tsp soy sauce or ½ tsp Worcestershire sauce to the butter-cream mixture for an extra umami punch. For a meaty flavor without actual meat, stir 1 tbsp mushroom powder (or 2 tbsp finely chopped dried mushrooms) into the butter.

I also love adding 1 tsp fish sauce to the vinegar mixture—just a hint adds complexity that pairs wonderfully with the potatoes' natural sweetness.
