How many calories are in a slice of pecan pie?

A 133g slice runs 541 calories, which makes pecan pie the heaviest thing on most holiday tables. Per 100g it is 407 calories, well clear of pumpkin pie at 243 calories per 100g and apple pie at 237 calories per 100g.

Why is pecan pie so much heavier than other pies?

Two things stack up. The filling is corn syrup and sugar, giving 59.6g of carbs per 100g with 25.2g of sugar per 100g inside that, and the nuts add 16.7g of fat per 100g on top. Pumpkin pie builds its filling from squash and evaporated milk instead, which is how it lands at 243 calories per 100g.

Can pecan pie fit into a diet?

A full slice at 541 calories is close to a third of many people's day, so the honest answer is a sliver. One ounce is 115 calories, and splitting a slice two ways is the move most people can live with. There is no light version: 407 calories per 100g is simply what this pie is.

Is pecan pie keto-friendly?

No, and not by a small margin. Net carbs are 57.5g per 100g, so one slice carries roughly 76g. Keto recipes swap the corn syrup for allulose or a sugar alcohol and get close on taste, but the standard pie is not in the conversation.

Does pecan pie have any nutritional value?

A little, and all of it from the nuts: 4.5g of protein per 100g, 2.1g of fiber per 100g and 99mg of potassium per 100g. Set against 25.2g of sugar per 100g and 275mg of sodium per 100g, it is a dessert rather than a source of anything.

Is pecan pie vegetarian or vegan?

Vegetarian yes, vegan no. The filling is set with eggs and most crusts use butter, which is why the row behind this entry carries 42mg of cholesterol per 100g. It is not gluten free either, since the crust is wheat flour.

How should you store pecan pie?

Because of the eggs, a cut pie belongs in the fridge and keeps 3 to 4 days there; a freshly baked uncut pie is fine on the counter for two. It freezes for a couple of months. A whole 833g pie is 3,390 calories, so freezing half is a genuinely useful habit.

Is pecan pie mostly nuts?

Less than the name implies. Raw pecans are 691 calories per 100g and almost entirely fat, while the pie is 407 calories per 100g because syrup, sugar and pastry dilute them. A typical slice holds around an ounce of pecans.
