It’s that time of year…time to start thinking about Thanksgiving dinner. It’s the one meal that you have to start planning way ahead of time but that’s all part of the fun!

Some people may love the turkey but I’m all about the Thanksgiving side dishes! Sweet potatoes are a Thanksgiving staple on our holiday table, but I’m not a fan of the traditional sweet potato casserole recipe with brown sugar and mini marshmallows. Marshmallows are meant for desserts and campfires, right?

The savory flavors of these baked sweet potato slices aren’t just perfect for Thanksgiving. They’re great all throughout the year with main courses like roast chicken, pork tenderloin, baked ham or even these Grilled Chicken Kabobs.

Kid approved: You’ll have no trouble getting your picky eaters to try this dish. The sweetness from the potatoes makes eating their veggies almost seem like they are eating dessert!

Do You Need to Peel Sweet Potatoes First?

Yes, you will get the best results with this recipe if you peel them first. If you have a vegetable peeler, that will help make it a lot easier.

How Do You Cut Sweet Potatoes?

This is a personal preference. This recipe calls for the sweet potatoes to be sliced but you can also cube them. Use a long and very sharp knife, since cutting through a large, sweet potato can take a little work. If you have a mandolin slicer, it can make this job super easy.

Can I Make These Potatoes in Advance?

When you are preparing several dishes, especially for holiday dinners, any short cut is helpful. That’s a great thing about this recipe! You can assemble this dish the night before then bake it the next day.

Or you can bake it the night before and just reheat it in the oven. They’re just as delicious the next day.

How Do You Roast Sweet Potatoes?

Once these sweet potatoes are seasoned, just cook them at 400 for 40-45 minutes depending on the thickness of the slices. The cooking time and oven temperature may change if you plan to cut them into cubes instead.

Variations and Add-ins

Spices: For a bit of smoky spiciness, add a touch of chili powder. Ground cinnamon works well with the herbs in this recipe also.

Maple Syrup: If you like your potatoes more sweet than savory, you can drizzle the tops of the potato rounds with a touch of maple syrup. It will work with the brown sugar to really sweeten them up. Honey will work well also.

Orange zest: Add a couple tablespoons of orange zest in with the herbs to really brighten up the flavors.

Nuts: Chopped pecans or walnuts add a little crunch that work so well with the creaminess of the potatoes.
