Using Baked Potatoes to Make Grilled Potato Slices

These grilled potato slices are just what you need coming off of your grill this Summer. They’re so easy and tasty, super buttery and delicious and go with almost anything else from the grill.

Potatoes really are great any time of the year. They are a perfect side dish to compliment so many main dishes. From fancy au gratin or whipped potatoes to a simple baker loaded with sour cream and your favorite toppings (which some people love as their main dish!).

And the variety of potatoes! Sweet potatoes, red potatoes, Yukon gold potatoes – all with different tastes and textures. We like using russet potatoes for this potatoes recipe because you can get bigger sizes and we like the consistency of the potato itself.

Highlighting the main ingredients needed for grilled potato slices

We have been grilling potatoes for a long time. However, we typically use foil packets on the grill (basically small diced potatoes with some seasoning, wrapped in aluminum foil covered in non-stick spray). This tends to steam the potatoes more than grill them.

We were looking to have a more crispy potato, without over or under-cooking and frankly, finding an easy way to do it! After a little experimentation, we found the perfect way to get the crispy grilled potatoes we were looking for.

They’re easy because you par-cook the potatoes in the microwave before you grill them, so they only take a few minutes on the grill. The taste secret is that you baste them in garlic butter, before you grill them AND after! 

They are also easy to handle because you cut them into rounds or slices. Fire up a hot grill (either charcoal or gas grill depending on your preference), place potatoes down in a single layer and less than 10 minutes later you have yet another perfect side dish using potatoes.

If I have the time, I do like using a charcoal grill. The smokiness of the grill just adds a great taste to the russet potatoes we like using. But a gas grill is a fine alternative if you are pressed for time or just don’t like the hassle of charcoal.

Pro Tip: You can easily par-cook the whole potatoes earlier in the day so they’re ready when you’re ready to grill. I made three large potatoes in this recipe and that’s enough for four servings. You can easily adapt this to however many servings you need, just melt more butter as needed.

I just love these crispy potato rounds and they also look fantastic with their golden brown color. You can serve “as is” with a little black pepper and salt or even dip in sour cream for that little something extra! This is such an easy way to make a delicious potato side dish.

Tips and Tricks for Using Baked Potatoes to Make Grilled Potato Slices:

  • You want to make sure that that you’re using large russet potatoes (i.e., bakers) so that your potato slices are a good size.
  • It’s important to pierce these large potatoes all over with a fork so that the steam can escape. If you don’t they could potentially explode in the microwave.
  • After the the potatoes have been baked in the microwave, you want to cool them completely so that they don’t break apart when you slice them into rounds. You can either refrigerate them or even put them in the freezer to speed up the cooling time.
  • I highly recommend grating the garlic with a microplane grater versus chopping it as you are making your garlic butter. The grated garlic will incorporate into the melted butter much better and won’t burn on the hot grill. Plus, grating garlic is so quick and easy.
