Sweet Potato Casserole (with Orange Juice)
Add Preferred SourceHonestly, the hardest part of making this Sweet Potato Casserole is waiting for it to come out of the oven. The thinly sliced sweet potatoes arranged in spiraling rings come out deeply caramelized, tender, and coated in a buttery glaze of fresh orange, maple syrup, brown sugar, and warm pumpkin spice. A pinch of flaky salt on top ties the whole thing together. It’s pure comfort on a plate.

I make this for Thanksgiving, Christmas, Easter, and potlucks because it’s one of those sides that looks gorgeous on the table without any kitchen stress. It feeds a crowd beautifully and can be prepped ahead so you’re not scrambling when guests arrive. Leftovers keep in the fridge for up to 4 days or freeze for up to 2 months, and they reheat beautifully in the oven.

Prep Your Dish
Preheat your oven to 375°F (190°C). Lightly spray a casserole dish, baking dish, or cast-iron skillet with cooking spray so the sweet potatoes don’t stick, and the glaze caramelizes without burning onto the pan.
You can also use a pie dish if that’s what you have. If you prefer to bake uncovered the entire time, just keep an eye on the glaze from the 40-minute mark so it doesn’t over-reduce.
Stack the Sweet Potatoes
Slice your sweet potatoes to ⅛ inch thick, then stack the slices into two large rings around the dish, filling the center with the remaining slices. A mandoline slicer makes getting consistently thin slices much faster and easier.
This layered arrangement helps the glaze coat every slice evenly as it bakes and gives the casserole that gorgeous, fanned presentation.
Make the Glaze
In a saucepan, combine the vegan butter, brown sugar, fresh orange juice, maple syrup, orange zest, pumpkin spice, salt, and fresh thyme leaves over medium heat. Cook for 4 to 5 minutes until the mixture is bubbling and the sugar has fully dissolved.
Pour the sauce evenly over the stacked sweet potatoes so every layer gets coated. For measuring your maple syrup cleanly, a large glass measuring cup makes pouring precise and mess-free.
Bake Until Tender and Golden
Bake for 45 to 60 minutes, until the sweet potatoes are fork-tender and the glaze has caramelized to a deep golden color. Check around the 45-minute mark since oven temperatures can vary. Using my silicone basting brush, I spoon some of the glaze from the edges back over the top halfway through baking to keep everything coated and glossy.
Garnish
Scatter fresh thyme leaves over the top and finish with a pinch of flaky sea salt if you like that sweet-savory contrast. Maldon Sea Salt Flakes are a great finishing touch here because they add crunch and a clean saltiness that cuts through the sweetness of the glaze.
Serve Warm
Serve the casserole straight from the dish while it’s still warm so the glaze stays silky and pourable around every slice.
Sweet Potato Casserole travels well to holiday dinners and potlucks when baked in a cast-iron skillet or oven-safe dish that doubles as a serving vessel. Cover tightly with foil to lock in heat and keep the glaze from drying out, then wrap the whole dish in a thick kitchen towel or slide it into an insulated casserole carrier for trips longer than 30 minutes.

Notes
- Slice consistently thin: Aim for ⅛ inch slices throughout so the sweet potatoes cook evenly. Thicker slices will stay firm in the center while thinner ones get too soft before the glaze sets.
- Stack tightly: Pack the slices snugly into the rings so they stay upright while baking. If they’re too loose, they’ll fall flat, and you’ll lose that beautiful layered look.
- Cook the glaze until bubbling: Don’t skip the 4 to 5 minutes of cooking time on the sauce. The sugar needs to dissolve, and the mixture needs to come to a boil before it goes over the potatoes, so it soaks in properly.
- Spoon the glaze back over halfway through: Around the 30-minute mark, use a spoon to scoop the pooled glaze from around the edges and drizzle it back over the tops of the slices to keep them coated and caramelized.
- Check for tenderness before pulling it out: Ovens vary, so start checking at 45 minutes. A fork or skewer should slide through the thickest slice without resistance when it’s done.
- Freeze in portions for easy reheating: Let the casserole cool completely, then cut into sections and freeze flat in a freezer-safe container. This way, you can pull out just what you need without thawing the whole dish.

How to Store Leftovers
Let the casserole cool completely before transferring leftovers to an airtight container and storing them in the fridge for up to 4 days. A good set of glass meal prep containers keeps everything fresh and makes reheating easy without transferring to another dish.
Reheat portions in the microwave or cover the dish with foil and warm it in the oven at 350°F until heated through. To freeze, portion the cooled casserole into a freezer-safe container and store for up to 2 months.
Thaw overnight in the fridge before reheating, and if the glaze looks a little dry after thawing, a quick drizzle of maple syrup warmed in the oven helps bring it back to life.
What to Serve With Sweet Potato Casserole
Since it’s rich, sweet, and deeply flavored, it pairs really well with savory sides that help balance it. A simple green salad with a tangy vinaigrette, roasted Brussels sprouts with garlic, or a creamy vegan mushroom gravy alongside a hearty lentil loaf are all great options for a full plant-based holiday spread.
For something lighter, steamed or roasted green beans, a wild rice pilaf, or warm dinner rolls work beautifully alongside the sweet, citrusy glaze. It’s rich enough to hold its own as a centerpiece side, so pairing it with simpler dishes lets it really shine.
