How to Cook Hasselback Potatoes on a Traeger Grill (Step-by-Step Guide)

Step 1

Preheat your Traeger grill to 375°F.

Step 2

Wash and dry the potatoes thoroughly. Using a sharp knife, make thin, parallel slices in the potatoes, not cutting all the way through.

Mix the minced garlic, melted butter, and finely chopped rosemary in a small bowl. Brush the mixture over the potatoes, making sure to get in between the slices.

Step 4

Rub the potatoes with olive oil and season with salt and pepper to taste.

Step 5

Place the potatoes on a sheet of aluminum foil and wrap them up tightly.

Step 6

Place the packet of potatoes directly on the grill grates and close the lid.

Step 7

Cook the potatoes for about 45 minutes to an hour, or until they are fork-tender.

Step 8

Remove the potatoes from the grill and carefully unwrap them from the foil. Place them back on the grill and cook for another 10 to 15 minutes or until the edges are crispy and browned.

Step 9

Serve the Hasselback potatoes hot, garnished with additional rosemary if desired.

Why Make Hasselback Potatoes on a Traeger Grill?

The Traeger grill adds a unique, smoky flavor to the potatoes that you can’t achieve in a traditional oven. The grill’s high heat also creates a crispy exterior and a soft, tender interior.

Tips for Perfectly Cooked Hasselback Potatoes

  • Use large, evenly shaped potatoes for the best results.
  • To make the cutting easier, place the potatoes between two wooden spoons, which will stop the knife from going all the way through.
  • Wrap the potatoes tightly in foil to prevent the butter from leaking out and to help them cook evenly.
  • Make sure to brush the butter mixture into the slices to ensure that every bite is flavorful.

Topping Ideas for Hasselback Potatoes

Hasselback potatoes are delicious on their own, but if you want to take them to the next level, here are some topping ideas:

  • Shredded cheese: Sprinkle your favorite cheese over the top of the potatoes and let it melt.
  • Sour cream and chives: Add a dollop of sour cream and sprinkle some fresh chives over the top.
  • Bacon bits: Crumble some bacon over the potatoes for a smoky, savory flavor.
  • Garlic aioli: Mix together minced garlic, mayonnaise, and lemon juice for a tangy, garlicky sauce.

I knew little about setting up, operating, cooking with, or maintaining a Traeger grill. I started this website to document my findings as I learn to "master the flames".
