Baked Sweet Potatos
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 roasted 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.
Why We Love This Recipe
- Sweet and savory flavor: Savory herbs and parmesan add so much savory flavor that’s a nice contrast to the natural sweetness in the potatoes. It’s the perfect combination!
- Easy recipe: This recipe uses simple ingredients with very little prep time. They’re great for those times when you’re busy cooking a gazillion things for a holiday meal.
- 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!
What’s Need to Make This Sweet Potatoes Recipe
- Sweet potatoes
- Olive Oil

How to Make Baked Sweet Potato Slices
Step 1. Preheat oven to 400 degrees.
Step 2. Peel then slice the sweet potatoes in about 1/8-inch slices and set aside.
Step 3. Pour the melted butter into a gallon sized plastic bag or a large bowl. Add in the olive oil, Parmesan cheese, Italian seasoning, minced garlic, brown sugar and thyme.
Step 4. Add the sweet potato rounds to the bag. Move around until they’re covered with the seasoning mixture.
Step 5. Arrange potatoes into rows in a 9×13 baking dish lined with parchment paper.
Step 6. Top with remaining mixture from bag and bake in a hot oven for 40-45 minutes (you may need to adjust cooking time for thicker slices). The brown sugar should be slightly caramelized.
Step 7. Remove from oven and serve hot.
To store leftover slices, allow them to cool to room temperature first. Then place them in an airtight container and refrigerate for up to 4-5 days.
Are Sweet Potatoes Healthy?
Not only is this a tasty and simple side dish, but it’s also healthy! Sweet potatoes are a good source of potassium, vitamin A, vitamin C, vitamin B6, fiber and many other vitamins and nutrients.

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 sliced sweet potatoes but you can also cube them. Use a long and very sharp knife, since cutting through a whole sweet potato can take a little work. If you have a mandolin slicer, it can make this job super easy.
If you make them this way, I would recommend placing the sweet potato cubes in a single layer on a baking sheet, then roasting at 425F for 25-30 minutes, until slightly crispy on the outside.
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.
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 on the sweeter side, you can drizzle the tops of your roasted sweet 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.
