Ingredients
- 3 lbs sweet potatoes, peeled and cut into 1-inch cubes
- 1/4 cup unsalted butter, melted
- 1/4 cup milk or unsweetened plant-based milk
- 1 tsp ground cinnamon
- 1/2 tsp ground nutmeg
- 1/4 tsp salt
- 2 tbsp pecans, chopped (optional topping)
- 1 tbsp maple syrup (optional topping)
Instructions
- 1
Preheat your oven to 400°F (200°C) and lightly grease a 9x13 inch baking dish. Place the cubed sweet potatoes in a large pot, cover with cold water, and bring to a boil over high heat. Cook for about 15-20 minutes, or until the sweet potatoes are fork-tender but not mushy.
- 2
Drain the cooked sweet potatoes thoroughly in a colander, allowing any excess steam to escape for a minute or two. Return the drained sweet potatoes to the empty pot. Mash the sweet potatoes with a potato masher or a sturdy fork until mostly smooth, leaving a few small chunks for texture.
- 3
Add the melted butter, milk (or plant-based milk), ground cinnamon, ground nutmeg, and salt to the mashed sweet potatoes. Stir vigorously until all the ingredients are well combined and the mixture is creamy and fragrant. Taste and adjust seasoning if needed.
- 4
Spread the sweet potato mixture evenly into the prepared baking dish. If using, sprinkle the chopped pecans over the top and drizzle with maple syrup for an extra touch of sweetness and crunch. This step takes about 2-3 minutes.
- 5
Bake in the preheated oven for 20-25 minutes, or until the casserole is heated through and the topping is lightly golden and fragrant. The casserole should be bubbling slightly around the edges when it's ready to serve.

Tips & Notes
- Softened butter should hold a fingerprint but not be greasy — if it melts on touch, it's too warm for creaming.
- Warm milk (not hot) is key for yeast-based recipes — aim for 105–115°F to activate yeast without killing it.
- Grade B (now labeled 'Grade A Dark') maple syrup has the most intense flavor for cooking.
