This oven baked 3-ingredients molasses sweet potatoes recipe is straight from my great aunt’s handwritten card box, the one she kept tucked behind old church cookbooks. She’d make these for Sunday dinners and every Thanksgiving, and the smell of molasses and butter in the oven still takes me right back to her tiny, warm kitchen. It’s the kind of old-fashioned, no-fuss recipe that feels almost too simple, but somehow tastes like you spent all afternoon on it. With just sweet potatoes, molasses, and butter, you get tender wedges coated in a dark, sticky glaze with caramelized edges—perfect for busy weeknights or holiday tables when you want something comforting and nostalgic without a ton of work.
These sweet potatoes are rich and cozy, so they pair really well with simple main dishes like roasted chicken, baked pork chops, or a pan-seared salmon fillet. I like to balance their sweetness with something bright and fresh on the side, like a green salad with a tangy vinaigrette or steamed green beans with a squeeze of lemon. For a holiday spread, tuck the foil tray right next to the stuffing and cranberry sauce and let everyone scoop out those sticky wedges. Leftovers are surprisingly great tucked into grain bowls with quinoa and roasted veggies, or reheated alongside scrambled eggs for a sweet-savory breakfast.
Oven Baked Molasses Sweet PotatoesServings: 4
Ingredients
2 pounds sweet potatoes, scrubbed and cut into thick wedges
3 tablespoons unsalted butter, melted (plus extra for greasing foil)
3 tablespoons molasses (unsulphured, regular or robust)
Directions
Preheat your oven to 400°F (200°C). Line a 9x13-inch baking pan or small sheet pan with heavy-duty aluminum foil, making sure the foil comes up the sides a bit. Lightly grease the foil with a little butter so the sweet potatoes don’t stick.
Scrub the sweet potatoes well and pat them dry. Leave the skins on for extra texture and nutrients. Cut each sweet potato lengthwise into thick wedges—aim for about 3/4-inch to 1-inch thick so they get tender inside but still hold their shape.
In a large bowl, whisk together the melted butter and molasses until smooth and glossy. It will look dark and a little syrupy.
Add the sweet potato wedges to the bowl and toss well, using a spatula or your hands to really coat every piece in the molasses-butter mixture. Make sure you scrape the bottom of the bowl so none of that glaze gets left behind.
Spread the coated sweet potato wedges in a single layer on the prepared foil-lined pan. Pour any remaining molasses-butter mixture over the top and gently nudge the wedges so they’re not stacked on top of each other. A little overlap is okay, but more space means better caramelized edges.
Cover the pan tightly with another piece of foil, crimping the edges to seal in the steam. Bake covered for 25 minutes, until the sweet potatoes are starting to soften.
After 25 minutes, carefully remove the top layer of foil (watch out for steam). Use tongs or a spatula to gently flip the wedges so both sides get a chance to caramelize. Spoon some of the melted molasses-butter from the bottom of the pan over the top of the potatoes.
Return the pan to the oven, uncovered, and bake for another 20 to 25 minutes, or until the sweet potatoes are very tender when pierced with a fork and the edges look dark, sticky, and caramelized. If you like them extra caramelized, you can turn the oven up to 425°F (220°C) for the last 5 minutes, keeping a close eye so the sugars don’t burn.
Once done, remove the pan from the oven and let the sweet potatoes sit in the foil tray for about 5 minutes. The glaze will thicken slightly as it cools and cling even more to the wedges. Serve straight from the foil-lined pan for that cozy, old-fashioned feel, spooning any extra dark syrupy glaze over the top.
Variations & Tips
If you want to stay true to the old-fashioned feel but tweak it a bit, you can add a small pinch of salt and a light sprinkle of ground cinnamon or nutmeg to the molasses-butter mixture before tossing the sweet potatoes—my great aunt did this on holidays when she wanted them to feel extra special. For a slightly less sweet version, swap one tablespoon of molasses for one tablespoon of melted butter, keeping the ratio close so you still get that sticky glaze. If you prefer cubes instead of wedges, cut the sweet potatoes into 1-inch chunks and reduce the uncovered bake time by about 5 minutes, checking early. To make cleanup even easier on a busy weeknight, toss the potatoes directly on the foil-lined tray instead of using a bowl. For meal prep, bake a batch on Sunday, then reheat portions in a hot oven or air fryer for a few minutes to re-crisp the edges. If you need a dairy-free option, use a neutral oil or coconut oil in place of butter, knowing the flavor will shift slightly but the molasses will still give you that deep, nostalgic sweetness.
