Roasted Sweet Potato Slices with Brown Sugar

by Easy Recipes

These delicious roasted sweet potato slices cook with the brown sugar on top so they get that caramelized yum factor.

I love sweet potatoes. They double as a starch and vegetable since they pack so much nutrition, which means I can serve it with almost any protein for an easy and healthy complete meal. I roast them whole a lot of the time, but sometimes I don’t have an hour for them to cook. Enter these roasted sweet potato slices!

These bad boys take just 5-10 minutes to prep, and then bake for 20-25 minutes. For the same reason that they cook faster than whole, they also cool faster than whole potatoes, so they’re at kid-friendly serving temperatures sooner. I love that the prep time is just a few minutes, since with toddlers running amok that’s often all the time I can be actively cooking in the kitchen. I also love that they’re so flavorful, and something all of us will eat; my three year old is very picky nowadays, but gobbles these up.

Let’s get started! Here’s what you’ll need:

Ingredients for roasted sweet potato slices on kitchen counter

  • 1.5 lb sweet potatoes (3 small, 2 medium or 1 giant one- my store always seems to have gargantuan potatoes)
  • 1 tbsp oil (olive, canola, etc)
  • 1/4 tsp salt (a sprinkle)
  • 1/4 tsp cinnamon (a sprinkle)
  • 1-2 tbsp brown sugar

You’ll also need a baking sheet, I love these ones (and yes, mine look a little beat up- they’ve seen a lot of use since I bought them in 2017), cutting board, and knife.


Step 1: First things first, go ahead and preheat your oven to 400 degrees F. Then rinse the potatoes and slice them into 1/2″ thick rounds.

Step 2: Spray your baking sheet with cooking spray or grease it with a bit of oil, then arrange the potatoes on the sheet in a single layer, ideally without them touching.  Drizzle the oil lightly over them.

Step 3: Then sprinkle the sweet potato slices with salt and cinnamon, and finish them with some brown sugar. I just sprinkle the salt and cinnamon directly from their containers, the brown sugar I apply by putting about a tablespoon in one hand and sprinkling it on with my fingers.

Step 4: Place the baking sheet in the oven, and set a timer for 20 minutes.

Finishing Touch: At this point they’re about done, but I like to turn up the oven to broil and give them 1-3 minutes (depending how close they are to the broiler- the closer they are the faster the sugar will bubble) to crystallize some of that brown sugar.

Variations of Roasted Sweet Potato Slices

Baby food: If you’re roasting these for a baby, go ahead and leave off the brown sugar from their slices. Roasted sweet potato slices are a great early food, and they have plenty of natural sweetness for our littlest ones. You can keep the cinnamon, babies are able to have it once they’re 6 months old.

Savory: Instead of cinnamon and brown sugar, garlic powder and rosemary go beautifully with these roasted sweet potato slices. I sometimes prefer them this way and do the batch half and half, since my husband always wants them with brown sugar.

Cheesy: Just like savory, but top with some parmesan cheese.

Questions about Roasted Sweet Potato Slices

Can I cook them faster at a higher temperature?

I don’t recommend it. You *could* cook them at 450 and get them done a bit faster, but it may dry them out some. I find 400 to be the best middle ground between time and temperature.

Do I need to peel the sweet potatoes first?

Nope! That’s extra work and I am all about passing on extra work here at Easier Motherhood. If your child doesn’t like the skins you (or they!) can peel the skin off after cooking- it’ll come off easily then.

Why is it so hard to cut the sweet potato?

Sweet potatoes are denser than regular potatoes, so they can be more difficult to cut. If you’re struggling to get your knife through, microwave it for a minute or two before slicing to make it easier.
