Candied yams are a cornerstone of Southern holiday tables, known for their tender texture and a thick, buttery syrup that tastes like liquid gold. The key to the perfect candied yam is a slow simmer, allowing the natural starches of the sweet potato to break down and absorb the warm spices of cinnamon and nutmeg.
Unlike many modern versions that rely on marshmallows, this traditional recipe focuses on creating a rich glaze that caramelizes as it bakes.
Ingredients
- 3 lbs (1.4kg) Sweet Potatoes: Peeled and sliced into 1/2-inch thick rounds.
- 1/2 cup Unsalted Butter: Sliced into pats.
- 1 cup Granulated Sugar: For the base sweetness.
- 1/2 cup Light Brown Sugar: Packed, for a deeper molasses flavor.
- 1 tbsp Ground Cinnamon: The essential holiday spice.
- 1/2 tsp Ground Nutmeg: Adds an earthy warmth.
- 1 tsp Vanilla Extract: To round out the flavors.
- A pinch of Salt: To balance the heavy sugar content.
Step-by-Step Instructions
- Prep the Potatoes: Peel your sweet potatoes and cut them into uniform rounds. Slicing them evenly is crucial for ensuring they all become tender at the same time.
- Layer: Arrange the sliced potatoes in a greased 9×13 inch baking dish. They can overlap slightly, but try to keep them in a relatively even layer.
- The Topping: Evenly distribute the pats of butter over the potatoes. In a small bowl, whisk together the granulated sugar, brown sugar, cinnamon, nutmeg, and salt. Sprinkle this mixture generously over the butter and potatoes.
- The Secret Splash: Drizzle the vanilla extract over the top. You do not need to add water; the potatoes will release their own juices to create the syrup.
- Bake: Cover the dish tightly with aluminum foil. Bake at 175°C (350°F) for 45 minutes.
- Caramelize: Remove the foil. Carefully spoon some of the accumulated syrup over the top of the potatoes (basting). Bake uncovered for another 15–20 minutes until the syrup has thickened and the potatoes are fork-tender.
- Rest: Let the dish sit for 10 minutes before serving. The syrup will thicken significantly as it cools slightly.
Quick Explain: Starch and Sugar
Sweet potatoes are complex carbohydrates that take about 1 hour to process in the digestive system. During the baking process, the heat breaks down the long-chain starches into simpler sugars, which then combine with the added butter and cane sugar to form a heavy syrup. This high-density glaze helps retain the internal moisture of the potato, resulting in a “melt-in-your-mouth” texture.

Note
For the best flavor, choose “Jewel” or “Garnet” sweet potatoes, which are often labeled as yams in U.S. grocery stores. They have a higher moisture content and a vibrant orange color that holds up beautifully in the syrup. If you prefer a “brighter” flavor, you can add a teaspoon of orange zest or a squeeze of fresh orange juice to the syrup before baking.
