How Many Calories Are In Red Potatoes? | Fast Calorie Tips

Calories In Red Potatoes By Size And Cook Method

Red potatoes land in the same calorie range as other white potatoes. The count changes with water loss during cooking and the weight you eat. A plain medium baked red potato is 151 calories at about 173 g per MyFoodData. Per 100 g cooked you’ll see about 87–89 calories, while a cup of diced raw (around 150 g) sits near 105.

Portion	Typical Weight	Calories
1 potato, small baked	138 g	≈ 123
1 potato, medium baked	173 g	151
1 potato, large baked	299 g	≈ 260
100 g baked (skin-on)	100 g	87–89
1 cup diced raw	150 g	≈ 105
1/2 cup diced raw	75 g	53

Those weights match the serving sizes used in the USDA-backed dataset that powers raw red potato entries. Cooked pieces lose water, so calories per gram go up a touch. That’s why 100 g baked averages near 87–89 kcal while 100 g raw reads lower.

What Changes When You Bake, Boil, Or Roast?

Baking dries the flesh a little, concentrating starch. Boiling keeps more moisture. Roasting lands between the two, and the number only jumps when oil joins the pan.

For tidy math, bake or boil without oil, then add flavor at the table. If you roast, use a light spray and a hot oven for color. That gives you crispy edges with fewer added calories.

Sizes That Match Real-Life Potatoes

Small, medium, and large are only rough labels. A scale tells the story. Here’s how common sizes line up with what you’ll see in nutrition data.

Small, Medium, Large: Quick Weights

Small red potato: about 138 g baked. Medium: about 173 g baked. Large: near 299 g baked. If you weigh raw before cooking, expect the number to drop after a bake due to water loss.

Kitchen Tips That Keep You On Track

• Weigh one medium once, note the grams, and use your eye next time.
• Slice thickness changes roast time, not calories. Oil is the swing factor.
• Skin-on adds a little fiber and potassium with no real calorie change.

Do Toppings And Oil Change The Count?

Fatty add-ins move fast. A tablespoon of olive oil adds about 119 calories, and a tablespoon of butter adds about 102. Sour cream (2 tablespoons) lands near 60, while a 30 g handful of cheddar is roughly 120. Use small spoons for sauces and you’ll stay closer to the potato’s base count.

For a lighter bowl, try Greek yogurt, chives, and lemon. Or mash in roasted garlic and a splash of broth for a creamy vibe without much extra energy.

Red Potatoes Compared With Other Potatoes

Red, white, and russet sit close on calories when weights match. What changes is texture and best kitchen use. Reds hold shape for salads and roasts. Russets fluff for mash and jacket potatoes. If you track a target, portion size beats variety choice every time.

Sweet potatoes get more press, yet reds bring similar energy per gram and shine in different dishes. If you want a creamier mash, mix half red and half russet. For a chunky salad that holds bite after dressing, reds are the easy pick, nicely.

Micronutrient Highlights In A Medium Baked Red Potato

Calories aren’t the whole story. One medium baked red potato also brings fiber and a mix of minerals and vitamins. The numbers below use the same 173 g serving from the baked entry above.

Nutrient	Amount	% DV
Potassium	~943 mg	20%
Vitamin C	~21.8 mg	24%
Vitamin B6	~0.37 mg	22%
Fiber	~3.1 g	11%

Portion And Prep Tips That Save Calories

Go Skin-On And Season Smart

Pepper, herbs, and citrus zest go a long way. Paprika, garlic powder, rosemary, dill, and lemon keep flavor high without extra energy.

Use Heat To Your Advantage

High heat gives color and bite. Fan-bake wedges on a rack, flip once, and finish with a mist of oil.

Build A Balanced Plate

Pair red potatoes with protein and non-starchy veg. Grilled fish, beans, leafy greens, or a crunchy salad steady the meal and keep hunger quiet.

Raw Weight Versus Cooked Weight

Red potatoes lose water as they cook. That changes volume, not energy. If you start with 200 g raw and bake it, the cooked weight might land near 170 g. Pick one method for tracking: weigh raw before cooking, or weigh cooked and use cooked values like 87–89 kcal per 100 g.

For a tray of roasted potatoes, weigh after cutting, roast with a light spray, then weigh again. If the pan goes from 600 g raw to 510 g cooked, and you serve four portions, each plate holds about 128 g cooked. Multiply 1.28 × 90 for about 115 calories from potatoes, then add any oil you used.

How To Measure A Cup Of Red Potatoes

Many home cooks lean on scoops. For diced raw red potatoes, 1/2 cup is about 75 g and 1 cup about 150 g. Fill the cup gently; don’t pack. For cooked cubes, 1/2 cup often lands near 78–80 g because moisture stays in the cells. When in doubt, check weight once and use that look for future meals.

For wedges or smashed potatoes, the cup reads differently since air sits between pieces. In that case, weigh the cooked portion once, note how it covers the plate, and use that visual later.

Air Fryer, Skillet, And Grill

All three routes work and the numbers stay friendly if the fat stays low. In an air fryer, spritz the basket and the potatoes, shake once, and finish hot. On a skillet, use a nonstick pan or a cast-iron sheet with a thin film of oil spread with a paper towel. On the grill, parboil first, then grill over medium to get marks without burning. In each case, count around 90 calories per 100 g of cooked potato before toppings.

Want extra crunch? Use smaller wedges, give them space, and let them sit a minute after cooking. Steam dries off, the crust sets, and the texture pops without extra oil.

Sample Day With Red Potatoes

Breakfast: 150 g skillet potatoes with onions and peppers (≈ 135 calories from potatoes). Lunch: 1 cup potato salad made with yogurt and mustard (≈ 105 from potatoes, 30–50 from the dressing). Dinner: a medium baked red potato (151) with grilled fish and greens. Total from potatoes: around 391 calories across three meals.

That spread gives you space for flavor without blowing the budget. If you add a tablespoon of olive oil at dinner, add 119. If you grate 15 g of cheddar instead of 30 g, tack on about 60 instead of 120. Small swaps keep totals steady.

Skin, Storage, And Prep Notes

Red potato skins are thin. Scrub well and leave them on for bakes, wedges, and salads. Store in a cool, dark place with airflow. Skip the fridge; cold can make the flesh sweet. Cut away green spots or sprouting eyes. When you cut in advance, keep pieces in cold water and drain before cooking.

Salt early for boiled cubes and late for roasts. Early salt seasons the interior during a boil. Late salt sticks to hot wedges fresh from the oven. For mash, warm a splash of milk or broth before folding in so the mix stays fluffy with less fat.

Quick Calorie Math You Can Trust

Use these anchors for fast checks: per 100 g cooked, aim for 90 calories; per medium baked potato, 151; per 1 cup diced raw, about 105. When oil or cheese joins the party, add the exact measure. A kitchen teaspoon equals about 5 g of oil, or ~40 calories. A level tablespoon of butter adds about 102. Keep a short list of your go-to combos on a note card inside a cupboard door.

For batch cooks, write the raw weight of potatoes on the tray before they go in the oven. After roasting, write the cooked weight. Divide by the number of portions. Grams per portion × 0.9 gives a fast estimate, since 100 g cooked is near 90 kcal.

Simple Serving Ideas With Clear Numbers

Fast Baked

Microwave scrubbed reds for 5–7 minutes, then finish in a hot oven to crisp. Count 151 calories for a medium, then add your topping math.

Sheet-Pan Roast

Cut into wedges, toss with spray oil, garlic, and rosemary. Roast at 220°C/425°F until browned. Figure about 90 calories per 100 g of cooked wedges without oil.

Potato Salad

Boil cubes until just tender, cool, and fold with yogurt, mustard, dill, and celery. Use a light hand with mayo or swap half for yogurt to trim extras.
