Looking for a new way to enjoy sweet potatoes at your holiday dinner? This Hasselback sweet potatoes recipe is topped with a delicious brown sugar pecan crumble that’s amazing as a side dish or dessert.

Made by simply peeling and slicing sweet potatoes and topping with the pecan crumble, this baked sweet potato recipe can be served right in the baking dish, going from oven to table.

What do I need to make Hasselback sweet potatoes?

Here’s a quick reference shopping list of the ingredients you’ll need for this recipe. Note that I’ve linked my favorite ingredients for this recipe from Target (affiliate links.) Target is great when you need ingredients last-minute, as you can do Target pick-up, Target drive-up or even delivery. All of these options can be done the same day.

  • Sweet potatoes – fresh, whole sweet potatoes from the produce section is what you’ll need. I don’t recommend canned yams or sweet potatoes, as these will be too mushy for this recipe. You’ll need about 3 lbs or 6 medium potatoes
  • Brown sugar – you can use either light or dark brown sugar for the crumble topping. To reduce the calories, you can also use Swerve Brown Sugar alternative which is a great healthier option.
  • Chopped pecans – you can purchase either whole pecan halves or pre-chopped pecans.
  • All-purpose flour – simple all-purpose flour is needed for making the crumble topping.
  • Butter – feel free to use either salted or unsalted butter for this recipe. I prefer using salted butter for most cooking, as I feel it has the best flavor.
  • Cinnamon – ground cinnamon adds an amazing flavor to the crumble topping and perfectly compliments the sweet potatoes.
  • Nutmeg – along with the cinnamon, adding nutmeg to the crumble topping mixture will add an amazing depth of flavor to the crumble topping.
  • Salt – salt is helpful in bringing out the sweetness and flavor in the crumble topping. Don’t leave this out.
  • Non-stick baking spray – I like and prefer avocado oil cooking spray, as it is better for you AND doesn’t leave a stick residue on your baking dishes.

How do I make Hasselback sweet potatoes?

The first step to making Hasselback sweet potatoes is to wash, peel and slice sweet potatoes. You can use a regular vegetable peeler to remove the outer skin.

To slice the sweet potatoes, I recommend using a large Chef’s knife or a Santoku knife, which I use and prefer. Slicing the potatoes approximately 1/8″ thick is ideal.

Do I leave the skin on sweet potatoes when making a Hasselback sweet potato recipe?

Leaving the skin on Hasselback potatoes is optional. For many Hasselback sweet potato recipes, the skin is left on and the potatoes are sliced three-quarters of the way through, leaving the potato in tact at the bottom.

However, many find the skin of sweet potatoes tough, chewy and dry, especially after baking. I find it best to peel the potatoes fully before slicing, having a more appetizing potato.

Ingredients needed to make a brown sugar pecan crumble topping for hasselback sweet potatoes.

Place the sliced sweet potatoes into a baking dish. A 12″ baking dish is what I use, however, you can also use an oval baking dish or a 9×9″ pan. Placing the potatoes on their side will help the potatoes retain their shape while baking and give you that “Hasselback” appearance.

Next, mix together the brown sugar pecan crumble. In a bowl, add the flour, brown sugar, pecans, cinnamon and nutmeg. Add in the melted butter, and stir together with a fork. Texture will be crumbly.

Adding the brown sugar pecan crumble to the Hasselback sweet potatoes:

Once you’ve made the brown sugar pecan crumble, simply crumble over the top of the sliced sweet potatoes. This does not have to be perfect. Simply place the crumble over the top and sides of the sweet potatoes.

Important Step: Cover the baking dish with foil before baking. Because the pecans will toast and brown well before the sweet potatoes are done baking, covering the dish with foil is important. The foil will keep the pecans from over-browning/burning.

The last 10 minutes of baking you can remove the foil and allow the pecans to toast before removing from the oven.

Frequently asked questions about Hasselback potatoes:

Why is it called a Hasselback potato?

Hasselback potatoes were first introduced in the 1940’s at a restaurant in Stockholm, Sweden. The restaurant’s name was the Hasselback which gained notoriety for using this simple slicing technique to potatoes, vegetables and meats.

What’s the difference between sweet potatoes and yams?

Sweet potatoes will have a reddish skin and bright orange flesh. Yams have a dark brown skin and have a lighter beige colored flesh. Yams will also grow much larger in size than a sweet potato.

What is the easiest way to cut Hasselback potatoes?

The best and easiest way to cut Hasselback potatoes is to place chopsticks on either side (long side) of the potato. Slice with a Chef’s knife or Santoku knife, using the chopsticks to stop the cut near the bottom of the potato.

Can you make Hasselback sweet potatoes in advance.

Yes, Hasselback sweet potatoes can be made in advance. This is a good options for a holiday meal, when you have limited oven space and time on the day of the dinner. Prep and cook the potatoes fully, cover the baking dish tightly with foil and refrigerate. Reheat the potatoes at 350 degrees for 20-30 minutes (covered with foil) or until fully warmed through.

Is sweet potato casserole a side dish or dessert?

Oh, this is a very controversial question, and one that many people have very different opinions on! Many consider sweet potatoes as a side dish, like mashed potatoes. However, when topped and baked with marshmallows or a brown sugar pecan crumble, it becomes very sweet, like a pumpkin pie, crumble or crisp. Many enjoy sweet potato casserole served with whipped cream or ice cream, thus making it a dessert. Either way it is served, it’s absolutely delicious!

Notes

Making in advance for a holiday meal? If you're serving this sweet potato recipe for a holiday meal, I am often asked it if can be made in advance. Yes, this sweet potato dish can be made in advance. You can either assemble it completely and wrap tightly in foil, and refrigerate overnight. Then bake before serving.
You can also assemble and bake the day before, let cool, wrap and refrigerate overnight. Reheat the day of the dinner by heating the oven at 350 and reheating for 20-30 minutes until fully heated through. Make sure the baking dish is covered with foil when reheating.
Storage & refrigeration: leftovers need to be refrigerated. Store in an airtight container or wrap the baking dish tightly with plastic wrap. Leftovers will keep 3-4 days, refrigerated.
