Ingredients for smashed fingerling potatoes

Quality potatoes and simple seasonings create restaurant-style smashed fingerlings with perfect texture contrast.

Ingredient Amount Notes
Fingerling Potatoes 🥔 1 ½ lb New potatoes preferred, uniform size
Unsalted Butter 🧈 ½ cup Cold, cubed for even coating
Extra-Virgin Olive Oil 🫒 2 tbsp High quality, fruity variety
Diamond Crystal Kosher Salt 🧂 1 ½ tsp Fine grain preferred
Fresh Rosemary 🌿 ¼ cup Finely chopped, stems removed
Fresh Thyme Leaves 🍃 ¼ cup Or 1 tsp dried thyme
Garlic Cloves 🧄 3 cloves Minced, for seasoning
Garlic Powder 🧄 ½ tsp For added depth
Ground Black Pepper 🌶️ ½ tsp Freshly ground preferred
Flaky Sea Salt 🧂 1 tbsp For finishing
Water 💧 4 cups For boiling

The fingerling potatoes are the foundation—uniform size ensures even cooking. New potatoes from the produce section (not the pre-washed bags) have thinner skins that crisp beautifully. For best results, source from a specialty market like Whole Foods or Trader Joe's, where they're typically fresher. Avoid potatoes with sprouts or soft spots. The cold butter cubes are crucial for achieving those crispy edges while maintaining creamy interiors—never use melted butter for this technique. If you can't find fingerlings, Yukon Gold potatoes cut in half lengthwise work as a substitute, though they'll be slightly larger.

No fresh rosemary? Dried rosemary at one-third the amount works, though fresh provides superior aroma. The garlic powder enhances flavor without altering texture—Penzeys brand offers the most consistent quality. For extra richness, swap half the olive oil for avocado oil, which has a higher smoke point. If you're serving this as a vegetarian main, add 1/2 cup crumbled feta cheese after roasting for a Mediterranean twist. The flaky sea salt should be added just before serving to maintain its delicate texture—Maldon or Jacobsen brands are ideal for this purpose.

Boiled potatoes should be used immediately for best results, but you can refrigerate them for up to 2 hours before smashing. Once smashed and roasted, they reheat beautifully—simply cover with foil and warm in a 350°F oven for 10-15 minutes. For meal prep, store in an airtight container for 3-4 days, though texture will be slightly softer. To freeze, arrange on a tray first to prevent sticking, then transfer to a bag for up to 3 months. Reheat from frozen by baking at 375°F for 20-25 minutes, adding a splash of water to maintain moisture.

Step-by-step instructions for smashed fingerling potatoes

Master these techniques and you'll achieve that perfect balance of crispy edges and creamy interiors every time.

1

👨‍🍳 Step 1: Boil and Prepare the Potatoes

Place the 1.5 lb fingerling potatoes in a medium pot and cover with the 4 cups water. Add 1.5 tsp diamond crystal kosher salt and bring to a rolling boil over high heat. Once boiling, reduce to medium-high heat and cook for 10-12 minutes until the potatoes are fork-tender but still hold their shape when pierced.

I like to test them by cutting one open—they should be soft inside but still slightly firm to the touch. Drain immediately in a colander and let them steam-dry for 1 minute to remove excess moisture. This step prevents the potatoes from turning soggy when smashed. While they're draining, preheat your oven to 425°F—this high temperature is crucial for achieving crispy edges.

2

🔪 Step 2: Slice and Smash the Potatoes

Using a sharp chef's knife, carefully slice each potato in half lengthwise. The goal is to create two equal halves—this ensures even cooking. Place the halved potatoes on a cutting board and use the flat side of your knife handle or a potato masher to gently press down on each half, creating shallow dimples without completely flattening them.

Here's the thing—you want to create surface area for browning without turning them into pancakes. Aim for about ¼-inch deep indentations. If you press too hard, they'll spread too much in the oven and lose their shape. Arrange the smashed potatoes on a parchment-lined baking sheet, leaving about ½-inch between each piece for even browning.

🍳 Step 3: Create the Herb Garlic Oil Mixture

In a small bowl, combine the 2 tbsp extra-virgin olive oil, 3 cloves minced garlic cloves, 0.25 cup finely chopped fresh rosemary, 0.25 cup fresh thyme leaves, 0.5 tsp garlic powder, and 0.5 tsp ground black pepper. Mix well to create a fragrant herb oil. This aromatic base will infuse the potatoes with deep flavor while helping create that crispy crust.

I always use fresh herbs here—their bright, vibrant flavors stand up to the richness of the butter. If you must use dried, double the amount but know it won't have the same impact. Pour this mixture evenly over the smashed potatoes, making sure each piece gets coated. Let them sit for 5 minutes while you prepare the butter mixture.

4

🔥 Step 4: Add Butter and Bake to Perfection

In a separate bowl, melt the 0.5 cup unsalted butter until it's completely liquid but not browned. Pour this melted butter evenly over the potatoes, coating them thoroughly. The butter should pool slightly in the smashed sections—this creates those luscious, creamy interiors while the exposed surfaces crisp up.

Bake the potatoes in the preheated 425°F oven for 25-30 minutes until the edges are deep golden brown and crispy, while the centers remain tender. You'll know they're done when you see golden-brown spots developing on the smashed surfaces and the potatoes release easily from the baking sheet. Real talk: don't walk away during the last 5 minutes—this is when the magic happens.

5

🥘 Step 5: Finish with Flaky Sea Salt

Remove the potatoes from the oven and immediately sprinkle with the 1 tbsp flaky sea salt. The salt should melt slightly from the residual heat, creating those beautiful salt crystals on the surface. Let them rest for 2-3 minutes before serving—this allows the juices to redistribute and the salt to adhere properly.

Serve immediately while still warm. The contrast between the crispy, golden-brown edges and the creamy, buttery interiors is what makes these potatoes truly exceptional. Each bite should deliver that perfect balance of textures and flavors—herby, garlicky, rich, and satisfying. Pair them with grilled meats or roasted vegetables for a complete meal.

Pro Tips For Making Smashed Fingerling Potatoes

  • Preheat That Pan: Cast iron or stainless steel—get it screaming hot for 5 minutes before adding the potatoes. I learned this the hard way: lukewarm pans mean mushy centers and uneven browning. High heat. Seriously, crank it up until a drop of water sizzles violently.
  • Smash, Don’t Mash: Use the flat side of a glass or wine bottle to gently press down on the potatoes—just enough to flatten them slightly. Overdoing it turns them into purée. Think "squished," not "crushed." (And resist the urge to press too hard when they’re hot; they’ll soften more as they cook.)
  • Salt the Potatoes First: Toss the raw fingerlings with olive oil, salt (about 1 teaspoon per pound), and rosemary before they hit the pan. The salt penetrates while they roast, not just season the outside. (Yes, even if you’re impatient like me—this makes a real difference.)
  • Butter at the End: Add cold butter and fresh rosemary in the last 2 minutes of cooking. Melted butter on hot potatoes can burn, and fresh herbs wilt if tossed in too early. Toss gently off the heat—just enough to coat, not drown. (Your future self will thank you.)

Wine and beer pairings for smashed fingerling potatoes

Crisp White Wine

For these buttery smashed potatoes, a dry Riesling or Sauvignon Blanc from New Zealand is my go-to choice. The bright acidity cuts through the richness while enhancing the herbaceous notes from rosemary and thyme.

I particularly love Cloudy Bay Sauvignon Blanc—its citrus and herbal notes complement the roasted garlic beautifully. Serve slightly chilled (45-50°F) to maintain crispness alongside the warm potatoes. 🍷

Herbal Red Pairings

If you're serving with grilled meats, a Pinot Noir or Grenache from the Rhône Valley brings harmony without overpowering. The red fruit notes in Pinot Noir mirror the roasted garlic, while Grenache’s earthiness pairs wonderfully with the flaky sea salt finish.

I recommend La Crema Pinot Noir or Guigal Côtes du Rhône Rouge—both offer enough body to stand up to the buttery potatoes. 🍇

Craft Beer Options

A hoppy pale ale or witbier balances the richness perfectly. The citrusy bitterness of a pale ale like Allagash White cleanses the palate between bites, while a Belgian witbier’s peppery notes enhance the rosemary flavor.

For a malty option, try a German Hefeweizen—its banana and clove undertones add unexpected depth. Serve at 48-52°F to preserve the beer’s crispness. 🍺

Seasonal Variations

For summer meals, swap the butter for olive oil and pair with a crisp Albariño from Spain. In winter, a full-bodied Chardonnay with oak notes complements the extra richness.

I’ve also enjoyed pairing these potatoes with a sparkling rosé—the bubbles refresh the palate while the fruitiness enhances the herb flavors. 💫

Non-Alcoholic Choices

For non-drinkers, a sparkling apple cider like Martinelli’s adds effervescence and subtle sweetness. Alternatively, a cucumber-mint infused water with a squeeze of lime keeps it refreshing. The mint echoes the thyme in the potatoes, while the lime brightens the buttery richness. Serve over ice for a crisp, cooling contrast. 💧

Frequently asked questions

1

Can I use regular potatoes instead of fingerlings?

While you can substitute Yukon Gold potatoes cut lengthwise, fingerlings are ideal because their small size and thin skins create perfect crispy edges when smashed. Regular potatoes tend to be larger and may not develop the same texture contrast. If using Yukons, halve them lengthwise for similar results.

2

Why do my smashed potatoes turn out mushy?

Over-boiling is the most common cause. Potatoes should be fork-tender but still hold their shape (10-12 minutes max). Drain immediately and steam-dry for 1 minute to remove excess moisture. Also, avoid pressing too hard when smashing—aim for shallow dimples, not pancakes.

3

How do I make these ahead of time?

Boil and smash the potatoes up to 2 hours ahead, then refrigerate uncovered. Before roasting, pat dry and coat with oil/butter as directed. Bake as usual, adding 5 extra minutes to crisp the edges. For freezing, arrange on a tray first to prevent sticking, then store in a bag for up to 3 months. Reheat at 375°F for 20-25 minutes with a splash of water.

4

What's the best way to reheat leftovers?

Cover with foil and warm in a 350°F oven for 10-15 minutes to restore crispiness. For microwave reheating, place on a plate with a damp paper towel for 30 seconds to refresh texture. Always finish with a sprinkle of flaky salt to revive flavor. Leftovers keep well for 3-4 days in an airtight container.

5

Can I make this dish vegetarian?

Boost flavor by adding ½ cup crumbled feta cheese after roasting or top with toasted pine nuts and lemon zest. For extra protein, serve with a white bean salad or grilled halloumi. The herby butter sauce works perfectly with plant-based mains too.
