This oven baked 3-ingredients nutmeg butter sweet potatoes recipe is one my mother-in-law first made for a small holiday dinner years ago, and it’s been on our table ever since. It’s the kind of side dish that feels special but couldn’t be simpler: just sweet potatoes, butter, and nutmeg. The rounds bake up warm, tender, and glossy in a glass casserole dish, and they practically melt in your mouth. It’s perfect for busy holidays or Sunday dinners when you want something cozy and homemade without a lot of fuss.
These nutmeg butter sweet potatoes pair beautifully with roasted turkey, baked ham, chicken, or a simple pork roast. I like to tuck the casserole dish right alongside green beans, a crisp salad, or steamed broccoli to balance the sweetness. They’re also lovely with a basket of warm dinner rolls to soak up the buttery juices. For a more casual night, serve them next to grilled sausages or rotisserie chicken and a simple side of applesauce for a comforting, family-friendly plate.
Oven Baked Nutmeg Butter Sweet PotatoesServings: 6
Ingredients
3 pounds sweet potatoes, peeled and sliced into 1/3-inch rounds
6 tablespoons unsalted butter, melted (plus a little extra for greasing the dish)
3/4 teaspoon ground nutmeg (plus a pinch more for sprinkling on top)
Directions
Preheat your oven to 375°F (190°C). Lightly grease a rectangular glass casserole dish (about 9x13 inches) with a small amount of butter so the potatoes don’t stick and the edges get a little caramelized.
Peel the sweet potatoes and slice them into even 1/3-inch rounds. Try to keep the slices the same thickness so they bake evenly and turn out tender all the way through.
Arrange the sweet potato rounds in the casserole dish in slightly overlapping rows, like shingles on a roof. This helps them bake up soft and lets the butter and nutmeg run between the layers.
In a small bowl or measuring cup, melt the butter in the microwave or on the stovetop. Stir in the ground nutmeg until it’s well combined and the butter looks speckled with warm brown spice.
Slowly pour the nutmeg butter evenly over the sweet potato rounds, lifting a few slices here and there with a fork or spoon so the butter can slip underneath. Use a brush or the back of the spoon to gently spread the butter so every slice gets a glossy coat.
Sprinkle an extra pinch of nutmeg over the top for a pretty, speckled finish. Cover the casserole dish tightly with foil to help the sweet potatoes steam and turn very tender.
Bake covered for 30 minutes. Then carefully remove the foil (watch for steam) and continue baking uncovered for another 20–25 minutes, or until the sweet potatoes are very tender when pierced with a fork and the tops are glistening in melted butter.
Let the dish rest for about 5–10 minutes before serving. The sweet potatoes will settle into the buttery juices and become even more melt-in-your-mouth. Serve warm straight from the glass casserole dish so everyone can see the bright orange rounds and breathe in that cozy nutmeg aroma.
Variations & Tips
For kids or picky eaters, you can cut the sweet potatoes into half-moons or small chunks instead of rounds; they’ll look more like familiar roasted potatoes and are easier for little hands to spear with a fork. If your family likes a touch of extra sweetness, drizzle 1–2 tablespoons of maple syrup or honey over the top along with the nutmeg butter (this technically adds another ingredient, but it keeps the same cozy spirit). For a slightly lighter version, reduce the butter to 4 tablespoons and cover the dish tightly during the full bake time to keep the potatoes moist. If you enjoy warm spices, you can swap half the nutmeg for cinnamon or add a tiny pinch of cloves for a deeper holiday flavor. To make this ahead, assemble the sliced sweet potatoes and nutmeg butter in the glass dish, cover, and refrigerate up to one day; bring to room temperature while the oven preheats, then bake as directed. Leftovers reheat nicely in the same casserole dish, covered with foil in a low oven, and they’re wonderful alongside eggs the next morning for a cozy breakfast.
