Why You Should Grill Your Potatoes Instead of Bake Them

  • Easy: Combining potatoes, onions, and some spice together in foil is so simple. No need to dirty up a bunch of pots and pans.
  • Tasty: Grilling food adds another level of flavor and these can be seasoned any way you like.
  • Get out of the kitchen: If it’s steaming hot who wants to turn on the oven? Grilling season doesn’t last all year so get the most out of it and get outside.

Key Ingredients and Easy Swaps

Here is a list of what you need to make grilled potatoes and some suggestions for alternatives.

  • Red potatoes: We used small red potatoes but you can use any kind of potato to make grilled potatoes. There is no need to peel them. Baby potatoes make for less chopping and are a great time saver. Swap in sweet potatoes or try out these grilled sweet potatoes
  • Onion: Onions always complement the flavors of potatoes. You can use any kind of onion including sweet onions, red onions, or traditional yellow onions. It's also great with gree onions or shallots.
  • Butter: Mix the potatoes and onions with butter or ghee. For a non-dairy alternative drizzle the potatoes with olive oil.
  • Seasoning: Dried rosemary, salt, and pepper add loads of flavor but feel free to use whatever dried or fresh herbs you have; basil, oregano, parsley, thyme, Italian seasoning, or curry powder. You name it and I am sure it will taste great on these potatoes.

How To Grill Red Potatoes

Just a few simple steps are required to make these potatoes.

  • Prepare a large piece of aluminum foil: Cut the potatoes and onions into quarters. (Kristen - there is nothing in the instructions about cut size and the photo only shows the potatoes.) Place both on the foil along with the butter and seasoning. Double wrap to ensure nothing leaks onto the grill.
  • To grill: Place the aluminum foil packet on the grill and cook for 15 minutes on each side. Check for doneness and continue cooking in 5-minute increments if needed.
  • To bake in the oven: Place the folded aluminum packet into an oven that has been preheated to 400 degrees. Check for doneness at the 25-minute mark and continue cooking accordingly.
  • Optional: After the potatoes are cooked I like to place them directly on the grill for a few minutes so they get brown and crispy.

Ways To Season Grilled Potatoes

There are endless ways to season these grilled potatoes but here are a few options.

  • Rosemary and Garlic: This classic combination of rosemary and garlic always tastes great. Along with the garlic add fresh thyme or sage. You could also use parsley, oregano, tarragon, or chives.
  • Buffalo or hot sauce: If you or your dinner guests happen to love hot and spicy dishes go ahead and coat the cooked potatoes with hot sauce or buffalo sauce. But wait until after they’re cooked and off the grill to drizzle on the hot sauce. No one would blame you for adding some crumbled blue cheese. 
  • Lemon and garlic: Coat the potatoes in olive oil, fresh lemon juice, and garlic along with some chopped parsley. Top everything with Parmesan cheese. 

What To Serve With Grilled Potatoes

The options are endless as to what to pair your grilled potatoes with but here are a few of our favorites.

How To Store Grilled Potatoes

  • Refrigerate: Leftover grilled potatoes will keep for 3-4 days in an airtight container in the fridge.
  • Freeze: You can place leftover potatoes in the freezer for up to 3 months.
  • Thaw: Thaw potatoes in the fridge overnight.
  • Reheat: To warm up leftovers place them in the oven at 350 for 15 minutes. You can microwave them though you may lose some of their crispiness.

How To Become The Resident Grilled Potato Expert

Here are a few things you can do to master the art of grilled red potatoes

  • Cut the potatoes the same size: Make sure all the potatoes are uniform in size so they cook up at the same pace.
  • Coat everything evenly: Each chunk of potato and onion needs to be well coated in butter or olive oil so it will cook properly. You also want the spices to be evenly distributed. To master this, place everything in a Ziploc bag and shake.
  • Invest in a vegetable basket: Instead of wrapping the potatoes in foil, you can use a vegetable basket that goes directly on the grill.

Frequently Asked Questions

Here are the mos

You don’t need to boil the potatoes before grilling them; they will cook with the steam in the foil pack. However, if you want to speed up the grilling process you can parboil them for a few minutes.

How long it takes to cook depends on how big the pieces of potato are. If you cut the potatoes into one-inch chunks it should take about 20-30 minutes to cook thoroughly.

If your eyes tear when you cut onions here are a few things to try:

  • Soak the onion in cold water before cutting it. The cold will chill the gases and lessen their impact.
  • Contact lenses may block the gases and make them sting less.
  • If you don’t wear contact lenses or glasses there is one more trick that may work. It sounds crazy but many people swear by it. Try sticking a piece of bread in your mouth while you slice. The bread will absorb some of the gases before they rise up to your nose and eyes. Strange but true!

Prepare one large piece of aluminum foil large enough to fit the potatoes and onions.


Place the potatoes and onions on the foil. Cut butter into small cubes. Place butter on top and season with salt, pepper, and rosemary. Fold the packet together and seal well. Wrap in one additional piece of foil to make sure it won’t leak on the grill.


Place on the grill and cook for 15 minutes. Flip over and cook for an additional 15 minutes. Try to make sure it isn’t on an open flame to prevent burning.


To cook in the oven: Preheat the oven to 400 degrees. Place folded packet on a baking sheet. Bake for 25 minutes and carefully check to see if potatoes are tender and fully cooked. Continue cooking in 5 minute increments if needed. Cooking time will vary based on size of potatoes.


Optional: Once the potatoes have cooked in the foil, I like to take them out and cook them right on the grill for a few minutes so they brown on the outside and get crispy.
