LogmaThe classic version runs about 200 kcal per 100 g once you count the butter, brown sugar, marshmallows and candied pecans. A plain mashed sweet potato with none of that is closer to 90 per 100 g.
Approximate values for a typical holiday serving, about 2/3 cup (150 g), of the classic marshmallow and pecan version.
Sweet potato casserole calories by serving
There's no standard scoop, and the recipe decides as much as the size. The same casserole can be a light side or a dessert depending on how much butter, sugar and topping goes in.
| Portion | Approx. amount | Calories |
|---|---|---|
| Classic casserole | 100 g | ~200 kcal |
| Light side serving | about half cup, 120 g | ~230 kcal |
| Typical holiday scoop | about 2/3 cup, 150 g | ~300 kcal |
| Big rich scoop | about 1 cup, 220 g | ~440 kcal |
| Marshmallow topping | about 2 tbsp | ~40 kcal |
| Candied pecan topping | about 2 tbsp | ~110 kcal |
Built from recipe figures that run from about 160 kcal for a small light serving to over 400 for a rich one. The butter, brown sugar, marshmallows and pecans are where most of the calories live, not the potato.
Why the casserole, not the sweet potato, runs up the number
- The butter and sugar: mashed in with brown sugar and butter, a plain sweet potato doubles in calories before anything goes on top.
- The marshmallows: they melt down small but are pure sugar, about 40 kcal for a couple of spoonfuls.
- The pecans: candied pecans are sugar plus nut fat, roughly 110 kcal for a 2 tablespoon scatter.
- The scoop: a party spoonful and a measured half cup are rarely the same size.
This is where a photo of your plate falls short. The casserole looks the same whether it was made with a little butter or a lot, and the brown sugar mashed through it is invisible. Saying "a scoop of sweet potato casserole with marshmallows and pecans" gives the estimate something to work with.
“A scoop of sweet potato casserole, some turkey and a spoon of stuffing.”
Example: Logma logs the casserole, the turkey and the stuffing as three items, about 620 kcal with macros, no weighing.
Sweet potato casserole on a Thanksgiving plate
| On the plate | Approx. calories |
|---|---|
| Scoop of sweet potato casserole on its own | ~300 kcal |
| Casserole, turkey and a spoon of stuffing | ~620 kcal |
| Casserole, turkey, stuffing and gravy | ~720 kcal |
| Big rich scoop with extra marshmallows | ~440 kcal |
On a full plate the casserole is one of the sweeter items, closer to a dessert than a vegetable. A smaller scoop leaves room for the rest of dinner.
Can you eat sweet potato casserole on a diet
Yes, with a sensible scoop. A typical serving is about 300 kcal, and sweet potato itself brings fibre and vitamin A. The issue is the toppings and the second helping, not the dish.
- Take a half cup scoop rather than a heaped one
- Go lighter on the marshmallow and pecan topping, or ask for an edge piece with less
- Fill the rest of the plate with turkey and plain vegetables
- Log it as part of the meal. One holiday plate won't undo your week if your calorie deficit holds
4 ways to lighten sweet potato casserole
- Less butter and sugar in the mash: sweet potato is already sweet, so you can cut both by half and still taste it.
- Thin the topping: a single layer of marshmallows or a light pecan scatter instead of a thick crust.
- Swap some topping for spice: cinnamon and nutmeg add warmth for no calories.
- Keep the scoop small: a half cup serving is about 230 kcal, a heaped cup is nearly double.
