How Many Calories Are In Fingerling Potatoes? | Handy Nutrition Facts

What Counts As A Serving Of Fingerlings

Fingerling potatoes are slender, two to four inches long, and naturally waxy. That texture stays firm when cooked, which makes a small portion feel satisfying. At home, most people eat about 1 cup cooked as a side, which is roughly 140–160 grams depending on moisture and cut size. If you prefer to count raw weight for meal prep, 150–200 grams raw usually cooks down to that same cup.

Because fingerlings vary, the most reliable way to track calories is by weight. Below is a quick table you can use with a scale. It shows calories from plain potatoes only—no salt or fat added.

Weight (Cook/Prep)	Raw, Flesh & Skin	Boiled, No Salt
50 g	38 kcal	43 kcal
100 g	77 kcal	86 kcal
150 g	116 kcal	129 kcal
200 g	154 kcal	172 kcal
300 g	231 kcal	258 kcal

Calories In Fingerling Potatoes Per 100 Grams (Raw Vs Cooked)

Per standardized nutrient data, raw potatoes provide ~77 kcal per 100 g, while boiled potatoes land around ~86 kcal per 100 g. These values come from lab analyses of potatoes with skin, prepared without salt or fat, and map well to fingerling texture and moisture. For reference, see potatoes, raw (per 100 g) and potatoes, boiled (per 100 g).

Why does boiled come out higher than raw per 100 g? During cooking, some water leaves the potato and the starches gel. The same grams now hold a bit less water and a slightly higher concentration of energy. When you roast with oil, another shift happens: fat clings to the waxy surface and pushes calories up quickly.

What Changes The Count Most

Added fat is the big swing factor. One level tablespoon of oil adds ~119 kcal. That spoon disappears fast when you toss fingerlings on a sheet pan, so measure first. Butter adds about 102 kcal per tablespoon.

Portion size comes next. A “just a few more” pile can turn a 130-calorie side into 250+ in a flash. Use a bowl that matches your target serving and fill it once.

Moisture and cut size also nudge the math. Smaller pieces lose a bit more water and take on oil more readily. Split-length fingerlings tend to absorb less than thin coins.

Serving Examples You Can Copy

Boiled, no fat: 1/2 cup (about 75–80 g) is ~65–70 kcal; 1 cup (140–160 g) is ~120–140 kcal.

Oven-roasted, light oil: 1 cup cooked (about 150 g) with 1 tsp oil in the pan adds ~40 kcal to the potato’s ~130 kcal, landing near ~170 kcal. If the pan uses 1 tbsp oil for the same amount of potatoes, plan on ~250 kcal per cup.

Skillet sauté: Oil coats more evenly, so even 2 tsp across a cup can add ~80 kcal. Use a spray bottle or measure by the teaspoon to keep control.

How To Cook Fingerlings For Fewer Calories

Boil Or Steam, Then Season

Cook until tender, drain, then season with salt, pepper, herbs, lemon, or vinegar. The texture stays creamy without needing butter. Toss warm potatoes with chopped parsley, dill, or chives and a squeeze of lemon for lift.

Oven-Roast With A Measured Spoon

Preheat a sheet pan, toss split fingerlings with 1–2 teaspoons of oil per cup of potatoes, and roast at 425°F (220°C) until browned. A measured spoon, not a “glug,” is the difference between a light 170-calorie side and one that sneaks toward 300.

Air Fry With A Light Mist

Air fryers crisp the skin with much less oil. A light spray or 1 teaspoon per cup keeps calories in check and still delivers crunch.

Carbs, Fiber, And Blood Sugar Basics

Potatoes are mostly carbohydrate with helpful potassium and vitamin C. Fingerlings are waxy, so they hold shape and feel dense. If you track carbs, pair your serving with protein and veg to keep the meal balanced and soften any blood sugar spikes.

Add-Ins And Toppers: What They Add

Here’s what common toppings contribute. Use these as quick plug-ins for your own recipes.

Add-In Or Topping	Portion	Extra Calories
Olive oil	1 tbsp (14 g)	119 kcal
Butter	1 tbsp (14 g)	102 kcal
Parmesan	2 tbsp (10 g)	42 kcal
Sour cream	2 tbsp (30 g)	59 kcal
Bacon bits	1 tbsp (7 g)	35 kcal

Season Big, Add Fat Small

Use bold, low-calorie seasonings first—garlic, smoked paprika, pepper, citrus zest, mustard, fresh herbs—and add measured fat last. A yogurt-based sauce stretches creaminess for fewer calories than straight sour cream.

How Fingerlings Compare To Other Potatoes

Calorie counts are similar across types when you match weight and cooking style. The waxy texture of fingerlings means they hold shape, so they do well with light oil. Floury potatoes, like russets, soak up more fat and can push totals higher when roasted or mashed with butter and cream.

Simple 3-Step Template For Any Recipe

1) Set Your Target

Pick a lane: 120-calorie cup (boiled or air-fried with a spritz), 170-calorie cup (light-oil roast), or 250-calorie cup (richer roast with more fat). Decide before you cook.

2) Measure What Matters

Weigh potatoes raw or cooked, not by eye. Measure oil with teaspoons or a squeeze bottle. One tablespoon is a big jump—~119 kcal—so smaller measures give you room for sauces.

3) Build The Plate

Pair fingerlings with lean protein and a high-volume vegetable. That combo keeps hunger in check without pushing calories up.

Storage, Leftovers, And A Handy Tip

Cooked fingerlings keep for three to four days chilled in a sealed container. Reheat in a hot pan with a teaspoon of oil or in an air fryer so the skin crisps again. Cool leftovers fully before chilling for best texture the next day.
