How To Roast Fingerling Potatoes In Oven
This is the core method for roasting fingerling potatoes. Follow these steps for a reliable, tasty outcome. The process is straightforward and requires just a few basic ingredients. You’ll be surprised at how such simple steps create such a flavorful dish.
What You’ll Need
- Fingerling Potatoes: About 1.5 to 2 pounds. This serves 4-6 people as a side.
- Oil: 2-3 tablespoons of a high-heat oil like olive oil, avocado oil, or grapeseed oil.
- Seasonings: Kosher salt and freshly ground black pepper are essential. You can add other herbs and spices too.
- Baking Sheet: A large, rimmed sheet pan is ideal.
- Parchment Paper or Aluminum Foil (optional): For easier cleanup.
Step-by-Step Instructions
1. Preheat Your Oven
Start by preheating your oven to 425°F (220°C). A hot oven is crucial. It ensures the potatoes start cooking immediately, leading to a better sear and crispier skin. Let the oven fully preheat for at least 15-20 minutes.
2. Prepare the Potatoes
Wash the potatoes thoroughly under cool running water. Use a scrub brush to remove any dirt, as you’ll be eating the skins. Pat them completely dry with a clean kitchen towel. Moisture is the enemy of crispiness.
Next, cut the potatoes. For most fingerlings, simply slicing them in half lengthwise is perfect. This creates a flat surface that will brown nicely against the pan. If some are very large, you can quarter them. Try to keep the pieces roughly the same size for even cooking.
3. Season the Potatoes
Place the dried, cut potatoes in a large mixing bowl. Drizzle with the oil. Use your hands or a spoon to toss them until every piece is evenly coated. The oil helps the seasonings stick and promotes browning.
Now, add your seasonings. Start with 1 teaspoon of kosher salt and ½ teaspoon of black pepper. Toss again. This is where you can get creative. Add minced garlic, fresh rosemary, thyme, smoked paprika, or grated Parmesan cheese after roasting for extra flavor.
4. Arrange on the Baking Sheet
Spread the potatoes out on your baking sheet. Make sure they are in a single layer with some space between each piece. If they are too crowded, they will steam instead of roast. This is a common mistake that leads to soggy potatoes.
For the best results, place each potato cut-side down. This maximizes contact with the hot pan, giving you those beautifully golden, crispy edges everyone loves.
5. Roast to Perfection
Place the baking sheet in the preheated oven. Roast for 20-25 minutes. Avoid the urge to open the oven door too often, as this lets heat escape.
After 20 minutes, check the potatoes. The bottoms should be golden brown. Use a spatula to flip them over. This allows the other side to get crispy too. Return them to the oven for another 10-15 minutes, or until they are tender all the way through when pierced with a fork.
6. Serve and Enjoy
Once roasted, remove the pan from the oven. Let the potatoes cool for a minute or two on the sheet. This helps them crisp up a bit more. Transfer them to a serving dish. Taste and add an extra pinch of salt if needed.
Serve them immediately while they are hot and crispy. They are a fantastic side for roasted chicken, grilled steak, or even with a fried egg on top for breakfast.
Tips for the Best Roasted Fingerling Potatoes
- Dry Potatoes Thoroughly: Never skip drying the potatoes after washing. Wet potatoes will not get as crispy.
- Use Enough Oil: Don’t be shy with the oil. It conducts heat and creates that desirable crunchy texture.
- High Oven Temperature: 425°F is the sweet spot. It cooks the potatoes quickly and creates a nice Maillard reaction (browning) on the outside.
- Don’t Crowd the Pan: Use two baking sheets if necessary. Overcrowding is the main reason potatoes turn out soft.
- Finish with Fresh Herbs: Tossing the hot potatoes with fresh chopped parsley, dill, or chives adds a burst of fresh flavor and color.
Flavor Variations to Try
The basic recipe is wonderful, but you can easily change the flavor profile. Here are a few ideas.
Garlic & Herb
During the last 5 minutes of roasting, add 3-4 cloves of minced garlic and 1 tablespoon of chopped fresh rosemary or thyme to the hot pan. Toss everything together and return to the oven. The garlic will become fragrant without burning.
Lemon & Parmesan
As soon as the potatoes come out of the oven, zest a lemon over them. Then, sprinkle with ¼ cup of finely grated Parmesan cheese and toss. The heat from the potatoes will melt the cheese beautifully.
Spicy Paprika
Add 1 teaspoon of smoked paprika and ½ teaspoon of garlic powder to the oil and salt mixture before tossing. This gives the potatoes a warm, smoky flavor with a lovely red color.
Common Mistakes to Avoid
Even simple recipes can have pitfalls. Here’s what to watch out for.
- Not Preheating the Oven: A cold start leads to uneven cooking and limp potatoes.
- Skipping the Drying Step: Water creates steam, which prevents crisping.
- Underseasoning: Potatoes need a good amount of salt. Season confidently.
- Stirring Too Often: Let them sit undisturbed to develop a crust. Flipping once is enough.
- Using a Cold Pan: Always put your potatoes on a room temperature or preheated pan, not one just out of the cupboard if it’s cold.
How to Store and Reheat Leftovers
Roasted fingerling potatoes are best eaten fresh. But if you have leftovers, store them in an airtight container in the refrigerator for up to 3 days.
To reheat, avoid the microwave, as it will make them soft. Instead, spread them on a baking sheet and warm them in a 375°F oven for about 10 minutes, or until heated through. You can also reheat them in an air fryer for 3-4 minutes to restore some crispiness.
What to Serve With Roasted Fingerlings
These potatoes are incredibly versatile. Their creamy texture and savory flavor pair well with many mains.
- Proteins: Roast chicken, grilled or baked fish, pan-seared steak, pork chops, or meatloaf.
- Vegetarian Options: Serve alongside a hearty lentil stew, a large salad with beans, or with roasted vegetables.
- Brunch: They are excellent with eggs any style, quiche, or breakfast sausages.
- Sauces: Try them with a dollop of sour cream, aioli, or a simple herb yogurt sauce for dipping.
Frequently Asked Questions
Do I need to peel fingerling potatoes before roasting?
No, you do not need to peel them. The skins on fingerlings are very thin and tender. They become deliciously crispy when roasted and add great texture and nutrients. Just give them a good scrub.
Why are my roasted fingerling potatoes not crispy?
The most likely causes are overcrowding the pan, not drying the potatoes enough before adding oil, or an oven temperature that’s too low. Ensure the potatoes are completely dry, spaced apart, and cooked in a properly preheated hot oven.
Can I roast fingerling potatoes with other vegetables?
Yes, you can. Choose vegetables with similar cooking times, like carrots or Brussels sprouts cut in half. Be aware that different veggies may release moisture, which could affect the crispiness of the potatoes. Tossing everything in oil and seasoning well is key for a good result.
How long does it take to roast fingerling potatoes at 400?
At 400°F, it will take slightly longer—about 30-40 minutes total. They may not get quite as crispy as at 425°F, but they will still be very tasty. Always check for tenderness with a fork.
What’s the difference between fingerling and baby potatoes?
Fingerlings are a specific varietal known for their shape and waxy texture. Baby potatoes are simply any type of potato that is harvested early while still small. Fingerlings have a denser, creamier texture, while some baby potatoes can be more starchy.
Can I use frozen fingerling potatoes?
It’s not recommended. Frozen potatoes will release too much water during roasting, making it nearly impossible to achieve a crispy exterior. For the best results, always use fresh potatoes for this recipe.
Troubleshooting Your Roast
If something didn’t go as planned, here are some quick fixes and reasons why.
- Potatoes are burnt on the bottom: Your oven rack might be too low, or the temperature is too high. Try placing the rack in the center position and use an oven thermometer to check your oven’s accuracy.
- Potatoes are hard in the middle: They needed more time in the oven. Next time, cut them into slightly smaller pieces or roast for an additional 5-10 minutes.
- Seasoning tastes bland: Potatoes absorb a lot of salt. Don’t be afraid to season generously before roasting and add a little more flaky sea salt after they come out of the oven for a flavor boost.
- They turned out oily: You may have used to much oil. Two to three tablespoons for 2 pounds of potatoes is usually sufficient. Toss them well to ensure an even, light coating.
Roasting fingerling potatoes in the oven is a fundamental kitchen skill that delivers fantastic results. The method highlights the potato’s natural qualities with minimal effort.
