How Many Calories Are In A Baked Yam? | Quick Facts

A baked yam (sweet potato) has about 90 calories per 100 g; a medium baked yam (~130 g) lands near 117 calories.

Calories In A Baked Yam (Per Size And Weight)

In many U.S. stores, “yam” on the sign points to the orange sweet potato. True yams are different tubers sold mostly in international markets. For calorie math, the baked “yam” most shoppers eat matches the sweet potato entry used by nutrition databases.

Use weight when you can. Baked flesh in the skin averages about 90 kcal per 100 g. That lets you scale any portion quickly: small (~60 g) ≈ 54 kcal, medium (~130 g) ≈ 117 kcal, large (~180 g) ≈ 162 kcal.

Quick Reference Table: Sizes, Weights, Calories

Portion Approx. Weight Calories (Plain)
Small yam ~60 g ~54 kcal
Medium yam ~130 g ~117 kcal
Large yam ~180 g ~162 kcal
1 cup baked cubes ~200 g ~180 kcal
1 ounce 28 g ~25 kcal

Roasting concentrates flavor with gentle browning but doesn’t add energy on its own. The swing usually comes from toppings. A drizzle of oil packs 119 calories per tablespoon, while a pat of butter adds about 102.

Why “Yam” Labels Usually Mean Sweet Potato

Grocery stickers keep the word “yam” for tradition. In the produce aisle, that name points to moist, orange-fleshed sweet potatoes rather than true tropical yams. Using the sweet potato profile keeps your log accurate for baked “yams” sold in most supermarkets.

For a verified baseline, nutrition tools that pull from the USDA-linked database list a 200 g cup of baked sweet potato flesh at about 180 kcal with 6.6 g fiber and standout vitamin A. See the MyFoodData baked entry and the USDA SNAP-Ed sheet for specifics.

Baked Yam Calories With Popular Add-Ins

Here’s how common extras change the count. Start with your plain base and add the row that matches your toppings.

Add-In Impact Table

Add-In Typical Amount Extra Calories
Butter 1 tbsp ~102 kcal
Olive oil 1 tsp ~40 kcal
Brown sugar 1 tsp ~16 kcal
Mini marshmallows 1/4 cup ~100 kcal
Greek yogurt 2 tbsp ~25–35 kcal
Pecans, chopped 2 tbsp ~100 kcal

Prefer savory? Swap butter for a spoon of plain yogurt, chives, and black pepper. You keep the creamy feel and trim a big chunk of energy compared with a buttered, sugar-topped potato.

Serving Ideas That Fit Different Goals

Light Side Dish

Split a medium yam, pinch of salt, squeeze of lime, and a light spray of oil. That keeps the add-on count tiny while boosting aroma and brightness.

Meal Builder

Top a large baked yam with black beans, corn, and salsa. The tuber brings slow carbs and potassium; the beans add protein and fiber. It lands like a burrito bowl, no tortilla needed.

Post-Workout Plate

Pair a medium potato with grilled chicken or tofu. You get handy carbs for glycogen plus lean protein for repair, all with a short ingredient list.

Macronutrients And Fiber Snapshot

Per 100 g baked flesh you’ll see about 21 g carbs, 3.3 g fiber, 2 g protein, and 0.2 g fat. Most energy comes from starches and natural sugars formed during roasting. That tiny fat number makes toppings the main swing factor.

True Yams Versus Sweet Potatoes

Shop West African, Caribbean, or Asian markets and you may see true yams with bark-like skin and white flesh. Those roots are starchier and drier, and they’re a different plant family. If you’re cooking those, expect a milder taste and a different texture.

In mainstream U.S. stores, the “yam” bin almost always holds sweet potatoes. That’s why the baked yam calories most shoppers need match the sweet potato profile shown here.

How To Weigh, Track, And Plate

Weigh Before Or After Baking?

Either works if you’re consistent. Weigh raw for recipes. Weigh cooked for meal prep. Just match the entry in your app to the state you measured: raw entries for raw weight; baked entries for baked weight.

Skin On Or Off?

Most database entries count flesh only. Eating the skin is fine and adds a bit of fiber and minerals. If you prefer skin included, add a small cushion to your tally.

Smart Swaps

Want the buttery feel for fewer calories? Try 1–2 teaspoons of olive oil plus a yogurt dollop. That spreads flavor well and keeps the finish silky.

Micronutrient Highlights Per 100 Grams

Nutrient Amount Notes
Vitamin A (RAE) ~960 µg Beta-carotene rich
Vitamin C ~20 mg Heat-sensitive
Potassium ~475 mg Fluid balance
Manganese ~0.5 mg Enzyme cofactor
Calcium ~38 mg Small addition
Fiber ~3.3 g Helps fullness

Values shift with size and moisture loss. Bake longer and hotter and the same potato weighs less, nudging the per-potato total down even though the per-100-g ratio stays near 90 kcal.

Glycemic Clues Without The Jargon

Baking can push sweetness up through light caramelization, but fiber keeps the ride steady for most people when portions are reasonable and the plate includes protein. Cooling, then reheating, can also lift resistant starch slightly, which some folks prefer for steadier meals.

Common Questions Answered Fast

Does Foil Change The Count?

No. Foil only affects steam and browning. Energy stays tied to the potato and whatever you put on it.

What About Marshmallow Bakes?

Holiday casseroles stack sugar and butter on top of a base that’s already sweet. It’s tasty, but portions can jump by hundreds of calories. Use spices and toasted pecans for texture and a lighter finish.

Can I Meal Prep Five At Once?

Yes. Bake a tray, cool, and refrigerate in skins for four days. Reheat in the microwave or air fryer. The count you logged on day one still applies if the weight hasn’t changed.

Bottom Line On Baked Yam Calories
