Sweet Potato Pie – Your new holiday favourite

Long before the sweet potato ever saw a marshmallow or a holiday table, it grew wild under the tropical sun of Central and South America. Ancient farmers in Peru and Ecuador were among the first to coax this humble root from the earth nearly 5,000 years ago. They understood its power long before scientists ever did: this vibrant, hearty tuber could feed families, travel well, and thrive where other crops struggled.

As civilizations expanded, so did the sweet potato’s reputation. Polynesian voyagers—some of the world’s most skilled navigators—are believed to have carried it across the Pacific long before Europeans set foot in the Americas. It took root on far-flung islands, becoming part of traditional Polynesian diets and even their myths. Later, when Spanish explorers arrived in the 1500s, they brought the sweet potato back across the Atlantic. It quickly spread through Europe, Africa, and Asia, where each region adopted it in its own delicious way.

In North America, the sweet potato became especially beloved in the southern United States, where warm weather and long growing seasons let the vines sprawl happily. Indigenous communities and later African communities cultivated it not just for its sweetness, but for its resilience.

While often confused with yams, the sweet potato is an entirely different plant. True yams belong to a different botanical family and are cultivated mainly in Africa and the Caribbean. The “yam” we see in North American grocery stores is simply a sweet potato wearing a borrowed name.

Beyond its comforting flavour and versatility, the sweet potato is a nutritional powerhouse. Rich in beta-carotene, which the body converts to vitamin A for healthy eyes, skin, and immunity.  High in fibre, supporting digestion and stable energy.  Packed with vitamins C, B6, and potassium.   Naturally gluten-free, low-fat, and gently sweet without added sugar.   Its deep orange flesh signals antioxidant strength, while purple varieties carry anthocyanins—compounds celebrated for their anti-inflammatory properties.

This week’s inspiration for the article was my beloved sister celebrating American Thanksgiving and all the fanfare, feasting and football that goes with it.  They will have eaten Sweet Potato Bake with gooey Marshmallows to top it off.   Being Canadian, the idea of topping sweet potatoes with marshmallows may feel more like dessert than dinner—and you’re not wrong.  The marshmallow-topped sweet potato casserole is a distinctly American Thanksgiving tradition, born in the early 1900s when a marshmallow company promoted recipes using their new product. It stuck, especially in the southern U.S., and became a nostalgic holiday staple.

In Canada, sweet potatoes tend to lean more savoury—roasted with herbs, whipped with butter and maple syrup, or baked into pies served beside turkey rather than as a sugary side dish. We appreciate their natural sweetness without pushing them fully into dessert territory.

Which brings us to a perfect middle-ground recipe: a gently sweet, warmly spiced sweet potato pie that behaves as a side dish, not a dessert—ideal for a Canadian Thanksgiving or Sunday roast, and timely for American Thanksgiving influence this week.

This pie has the creaminess of a casserole, the structure of a gratin, and just enough spice to feel special—without a marshmallow in sight.

For the filling:

• 2 large sweet potatoes (about 2 lbs), peeled and cubed
• 3 tbsp butter

    Place cubed sweet potatoes in a pot of salted water. Boil until very tender, 12–15 minutes. Drain well.

   Stir in the eggs, evaporated milk, maple syrup, spices, salt, and thyme (if using).
   
3. Prepare the crust
    Press your cracker crust into the dish, or place an unbaked pastry shell into the pie plate.
