| Ingredient | Amount | Notes |
|---|---|---|
| Fingerling Potatoes 🥔 | 1 ½ lb | New potatoes preferred, halved lengthwise |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | High-quality, fruity variety |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Fine grain preferred |
| Garlic Powder 🧄 | ½ tsp | Freshly ground preferred |

The potatoes are non-negotiable—fingerlings or new potatoes with their waxy texture are crucial for that perfect tender-crisp contrast. Trader Joe's and Whole Foods carry excellent organic varieties, but any small, firm potatoes work in a pinch. Halve them lengthwise before tossing so they cook evenly. For an extra flavor boost, look for red or yellow fingerlings—their skins add natural sweetness. The secret to crispy edges? High-heat roasting and that cornstarch toss—trust me on this one, it's a game-changer!
No fresh rosemary? Dried works at half the amount, but fresh gives that unmistakable aroma. Short on olive oil? Avocado oil works beautifully too—it's got a higher smoke point. The smoked paprika is what gives these potatoes that subtle gourmet touch—don't skip it! For extra crispiness, pat them dry before tossing in the oil. And if you're feeling fancy, toasted sesame oil in the final drizzle adds an Asian-inspired twist that's absolutely irresistible. The cornstarch is non-negotiable for that perfect crunch, but if you're out, a sprinkle of semolina works in a bind.
These potatoes reheat like a dream—just 5 minutes at 400°F restores that crispy perfection. Store leftovers in an airtight container for up to 3 days, but honestly, they disappear faster than that. For meal prep, freeze them for up to 3 months—thaw and reheat for a quick side dish. The best part? The flavors deepen overnight, so leftovers often taste even better than the first batch. Keep a batch in the fridge for those spontaneous dinner guests—you'll be the hero of the hour!

Step-by-step instructions for crispy-edged, buttery-soft fingerling potatoes
Here's how to transform humble fingerlings into restaurant-quality bites with perfect texture every time.
Prep and Parboil for Maximum Flavor
Start by preheating your oven to 425°F—this high temperature is key to achieving that coveted crispy exterior. While it heats, place the 1.5 lb fingerling potatoes in a large pot and cover with cold water. Add 1 tsp of the diamond crystal kosher salt and bring to a boil over high heat.
Once boiling vigorously, reduce heat to medium-high and cook for 5-6 minutes until the potatoes are just tender when pierced with a fork. Drain immediately in a colander and return them to the pot. This parboiling step ensures they cook through evenly while developing flavor—don't skip it, or you'll end up with uneven doneness.
Toss with Herb-Oil Mixture
In a large bowl, combine the 0.25 cup extra-virgin olive oil, remaining 0.5 tsp diamond crystal kosher salt, 0.5 tsp garlic powder, 0.5 tsp smoked paprika, 0.25 tsp fresh rosemary, 0.25 tsp fresh thyme leaves, and 0.5 tsp freshly ground black pepper. Whisk vigorously until the mixture is emulsified and fragrant—this is where the magic happens.
Add the warm potatoes to the bowl and toss gently but thoroughly to coat every surface. I like to use my hands here for even distribution, making sure the oil penetrates the crevices. The potatoes should glisten with the oil mixture—this ensures maximum crispiness when roasted. Let them sit for 5 minutes while you prepare your baking sheet.
Apply Cornstarch for Extra Crispiness
Transfer the coated potatoes to a rimmed baking sheet lined with parchment paper, spacing them ½ inch apart—crowding will steam them instead of crisping. In a small bowl, mix the 1 tbsp cornstarch with 1 tsp of the remaining herb oil mixture until it forms a fine powder. Sprinkle this evenly over the potatoes, shaking off any excess.
The cornstarch creates a crispy lattice on the surface that amplifies that satisfying crunch. Here's the thing—don't press down on the potatoes when arranging them. You want them to maintain their shape while developing maximum surface area for browning. The cornstarch will caramelize beautifully during roasting, creating that perfect textural contrast we're after.
Roast to Golden Perfection
Slide the baking sheet into the preheated oven and roast for 20-25 minutes, stirring once halfway through the cooking time. You're looking for potatoes that are deep golden brown on the edges with a crisp texture when pressed gently. The internal temperature should reach 205°F—this ensures they're tender all the way through.
Watch carefully during the last 5 minutes—this is when they develop that perfect balance of crispy exterior and buttery interior. If they're browning too quickly, move the sheet to the middle rack. If they need more color, return to the top position. The aroma filling your kitchen at this point is worth every minute of waiting.
Rest and Serve Immediately
Remove the potatoes from the oven and let them rest on the baking sheet for 3-5 minutes. This resting period allows the residual heat to finish cooking them through while preventing a temperature shock when served. The potatoes should be piping hot with edges that shatter at the slightest touch.
Serve immediately while they're at their peak texture—these potatoes won't wait. The combination of crispy edges, tender centers, and aromatic herb oil will have your guests asking for seconds. For extra presentation, sprinkle with additional fresh rosemary and fresh thyme leaves just before serving. Pair with grilled meats, fresh salads, or simply enjoy as a stand-alone appetizer.
Pro Tips For Making Best Fingerling Potato Recipe Ever
- Boil Until Fork-Tender: I learned this the hard way—fingerlings need a solid 12-15 minutes in boiling water (not just until they float). They’re dense little things, and undercooking leaves you with a meal that’s more sad than satisfying. Test one early: it should pierce like butter.
- Salt the Water Generously: Diamond Crystal kosher salt is lighter than table salt, so don’t skimp—aim for 1½ tablespoons per quart of water. I used to eyeball it, and the potatoes always tasted bland. This isn’t the time to be shy; the salt penetrates better when the water’s already seasoned.
- Dry Them Thoroughly First: Pat those potatoes completely dry with a towel before roasting. Wet skin = steam instead of crisp. I know, it’s tedious, but trust me: the difference between a sad, damp potato and one with actual texture is just a few extra minutes with a kitchen towel.
- Roast in Two Batches: Crowding the pan turns your crispy dream into a soggy nightmare. Use two sheets at 425°F for 25-30 minutes, flipping once. Yes, it takes longer, but you’ll get that perfect golden crust without a single sad, undercooked potato in the mix. (Your future self will thank you.)
Make-ahead tips for best fingerling potato recipe ever
Prep Ahead Strategy
Start your prep the night before by washing and halving the 1.5 lb fingerling potatoes, then storing them in a sealed container in the fridge. This saves 15 minutes of work on cooking day.
I like to keep them in a bowl of cold water to prevent drying out—just drain and pat dry before roasting. 🥔
Overnight Flavor Boost
Combine the seasoning blend—0.25 cup olive oil, 1.5 tsp salt, 0.5 tsp garlic powder, 0.5 tsp smoked paprika, and herbs—in a jar and refrigerate overnight. The flavors meld beautifully, creating a more complex taste profile. Shake vigorously before using to re-emulsify the oil.
Cornstarch Pre-Mix
Mix the 1 tbsp cornstarch with 1 tsp olive oil in a small container up to 3 days ahead. Store in an airtight container—this pre-mix is perfect for achieving that signature crispy texture without last-minute fuss. Just sprinkle directly onto the potatoes before roasting.
Storage Containers
Use glass Pyrex containers with snap-on lids for storing leftovers—they maintain crispiness better than plastic. Portion the potatoes into individual containers right after cooking to preserve texture. I keep one container in the fridge for quick weeknight meals and another in the freezer for emergencies.
Reheating Secrets
For perfect reheating, spread cooled potatoes on a baking sheet and bake at 400°F for 5-7 minutes until crispy again. Microwaving works in a pinch, but add 1 tsp water and cover with a damp paper towel to restore moisture. The cornstarch coating helps maintain crispiness even after reheating. ✨
Freezer Prep Tips
For long-term storage, arrange potatoes on a tray and freeze until solid (about 1 hour). Then transfer to a freezer bag with all seasonings—this prevents sogginess. Thaw overnight in the fridge before roasting as directed. The texture remains excellent even after freezing, making these perfect for meal prep. ❄️

Frequently asked questions
Can I use regular potatoes instead of fingerlings?
While you can use regular potatoes, fingerlings are ideal because their small size and waxy texture create that perfect crispy exterior with tender centers. Russet potatoes will work in a pinch, but they'll need 10-15 extra minutes to cook through and may turn mushy. For best results, stick with fingerlings or new potatoes—their natural sweetness and firm flesh are what make this recipe shine.
Why does the recipe call for parboiling?
The parboil step is crucial for even cooking—it jumpstarts the potatoes so they finish perfectly crispy without turning rubbery. Without it, the outsides might burn before the centers cook through. Think of it like preheating your oven: it ensures consistent results every time. The 5-6 minute boil also helps the seasoning penetrate deeper for maximum flavor.
What if I don't have cornstarch?
No problem! Use 1 tbsp all-purpose flour or semolina as a substitute—they'll still give you that satisfying crunch, though cornstarch creates the crispiest texture. For extra crispiness, try panko breadcrumbs (use 2 tbsp**)—just toss them with a little olive oil before sprinkling. The key is to use something that creates a dry, starchy coating.
Can I make these potatoes ahead of time?
These reheat beautifully. Store leftovers in an airtight container for up to 3 days, then refresh by baking at 400°F for 5-7 minutes until crispy again. For freezing, arrange potatoes on a tray, freeze until solid, then transfer to a bag with seasonings. Thaw overnight in the fridge before reheating. The cornstarch helps maintain crispiness even after freezing.
How do I prevent soggy potatoes?
Sogginess happens when moisture steams the potatoes instead of crisping them. Always pat them dry after parboiling, use high heat (425°F), and space them ½ inch apart on the baking sheet. The cornstarch coating is your secret weapon—it creates a barrier that locks in crispiness. For extra insurance, roast on the middle rack where heat circulates evenly.
