I’ve been waiting to share this recipe with y’all for the perfect time—but then I realized that any time is the perfect time for this sweet potato recipe.

While we traditionally have enjoyed sweet potato dishes in the fall and winter months, you can make them year-round. And this one is no different.

It looks fancy, yes, but it’s actually quite simple to put together, assuming you have the right tools. (And I bet that you do!)

Come learn how to hasselback sweet potatoes, as well as find out how to make them taste extra delicious for any occasion.

Why I love this recipe:

Our entire family loves sweet potatoes, and this recipe is no different. However, it feels fancier than our usual sweet potato fare.

I mean—look at those gorgeous potatoes!

The thing I love about this Hasselback Sweet Potato recipe is that the sweet potatoes crisp up beautifully and taste amazing.

They’re the perfect balance of naturally sweet with savory. (After all, we rub them with a little oil and dried herbs to make them sing.) Then we top ‘em with a butter-parmesan sauce that sends them over the top.

So so if you’re looking for a recipe with a bit of sweetness (from either brown sugar or maple syrup), this one isn’t for you.

Hasselback Sweet Potatoes make for a hearty side dish, whether you’re serving them alongside dinner or are making them to share for a holiday.

Also, you can double or triple the recipe if you’re making these for a holiday table, which we all should love!

In addition to these tools, you’re also going to need some ingredients.

  • Sweet potatoes—we’re going to use three medium-sized ones. They’ll weigh in around 1.65 lbs. I recommend purchasing three that are similar in size so they can cook evenly.
  • Extra virgin olive oil—this is the neutral oil we’re going to use for the seasoning rub for our sweet potato recipe. You could use regular ‘ol olive oil, too.
  • Spices—we’re using a combination of dried thyme, rosemary and oregano to give our potatoes extra flavor, as well as kosher salt and black pepper! Be sure that your jars of dried herbs are fresh because they lose their flavor as they age.
  • Garlic—as if I could ever share a savory recipe here without minced garlic, right? The recipe calls for two cloves, but feel free to measure with your heart.
  • Unsalted butter—this is going to be the base of our butter-parmesan drizzle that we use to finish the sweet potatoes. I recommend using unsalted butter because the parmesan adds enough saltiness.
  • Grated parmesan cheese—the real deal, please, and not the stuff you might find in a shelf-stable bottle. It adds an awesome pop of flavor and saltiness to finish the recipe.

Extra topping ideas:

In case these Hasselback Sweet Potatoes aren’t enough on their own with the spice rub and a butter-parmesan sauce, here are a few other things you could add to them:

  • Bacon crumbles
  • Toasted nuts
  • Cheese—if you’re feeling really fancy, consider using slices and fitting those between the rounds of the sweet potatoes to make them extra gooey while baking
  • Sour cream

How to make Hasselback Sweet Potatoes

Preheat the oven. Spray a baking dish (with sides!) with nonstick baking spray or rub it with a little oil. This will prevent the potatoes from sticking. Set aside.

Prep the potatoes. Wash the sweet potatoes well, thenplace between two wooden spoons or metal skewers on a wooden cutting board.

With a sharp knife, cut even slices into the sweet potato, stopping about ¼” from the bottom. The spoons/skewers should prevent you from cutting the entire way through.

Prep like a pro! Sweet potatoes are sometimes tougher than other potatoes, so I like to ensure my knife is very sharp and that I am also being very intentional with my slices. Work slowly and be careful until all the sweet potatoes have been sliced.

Repeat the same with all sweet potatoes and place on the baking tray.

Make the rub. In a small bowl, mix the olive oil, thyme, rosemary, garlic, salt and pepper together until combined.

Rub the sweet potatoes with the oil mixture, and settle into the baking dish.

Bake for 45 minutes on the center rack of the oven until tender. Double check with a skewer to confirm before removing.

Since the size of sweet potatoes can be variable and some are thicker than others, I always recommend checking the biggest one you’ve got in the pan.

Once cooked through, remove the potatoes from the oven.

Mix the butter-parm sauce in a small bowl. Stir until combined.

Drizzle the butter-parmesan directly over the sweet potatoes immediately after they are removed from the oven.

Serve warm, and enjoy!

Frequently Asked Questions

Is there a trick to cutting sweet potatoes?

I recommend using a sharp knife and going slow because some sweet potatoes can be tough.

What is the hasselback technique?

The hasselback technique refers to how the sweet potatoes are sliced. Basically, we’re cutting them almost all the way through in thin little rounds, but not cutting through the bottom of the sweet potato. We want them to stay together and roast together.

Who invented the hasselback potato?

According to Wikipedia, a chef named Leif Elisson, invented this at a restaurant in Stockholm in the 1950’s.

Quick Tips and Tricks for the best baked sweet potato slices

  • Choose the right sweet potatoes: Purchase ones that are similar in size and shape so they can cook evenly. Sweet potatoes can be so widely variable, so I like to find the ones that are evenly shaped and on the smaller end so that they don’t take extra time to bake.
  • Use a sharp knife and the wooden spoon/metal skewers as a guide. I cannot stress enough how important the sharp knife is here because otherwise, you could have trouble slicing your sweet potatoes. The wooden spoons/metal skewers are super important, too, because they will help you not cut too far into the sweet potato.
  • How to store: Place in an airtight container, and store in the refrigerator for up to 3 days. Reheat in the microwave until warm.
