Hasselback Potatoes

Making a classic sweet potato casserole into something fun and creative such as a Hasselback Sweet Potato Casserole will definitely grab your loved one’s attention at the dinner table.

To make Hasselback potatoes, the first thing that needs to be done is to scrub them clean.

For this particular recipe, the potatoes are skinned so that there is no crispiness to the potatoes and in place, there’s a smooth buttery flavor. The skin can be left on if desired but I prefer to make it without.

To slice the potatoes, start by cutting into the end of the potato and cutting just until there is 1/4″ left. Repeat the process with new slices until you reach the other end of the potato.

Sweet Cinnamon Glaze

To make the sweet glaze that goes on these potatoes, butter is melted on the stovetop and brown sugar is added to the mixture. It’s important to allow the brown sugar to meltdown and dissolve into the butter. This prevents the mixture from being grainy.

Once the brown sugar is melted, add the other spices and stir to mix well. One-quarter cup of the mixture is set aside so that it can be used later on during the baking process.

Baking Hasselback Sweet Potatoes

The glaze is then drizzled on the potatoes and the potatoes are placed in the oven covered with aluminum foil for 50 minutes.

Once the 50 minutes are up, the remaining glaze is basted onto the potatoes and the aluminum foil is removed.

After the 20 minutes is over, the oven is set to the Broil setting and mini marshmallows are added to the sweet potatoes. The casserole is added back to the oven for about 3 minutes or until the marshmallows start to brown.
