Grilled potatoes in foil packets are an easy and delicious side dish to serve at your next BBQ.
Not only do they add a flavorful element to your meal, but they are also simple to make.
This recipe will teach you how to make the perfect foil potatoes that will be sure to be a hit with your guests. Plus, by prepping the potatoes in foil packets, you’ll be able to keep your potatoes tender and juicy while grilling.

One thing I love about these grilled potatoes is that clean-up is a breeze! Simply throw away the foil after they’re cooked.
Grilling potatoes in foil is also a healthier alternative to frying or roasting them in oil.
I simply spray the foil with olive oil spray so the potatoes won’t stick. I also add plenty of seasonings so they’re full of flavor, but I leave out the butter to keep them healthy.
Selecting the Perfect Potatoes for Grilling:
Selecting the right type of potatoes can make all of the difference when grilling them in foil packets.
One of the best options for grilling is the red potato. They have a thin skin and firm flesh, making them ideal for cooking on the grill.
They retain their shape during grilling and offer a slightly sweet and buttery flavor.
Another great option is the Yukon Gold potato. They have a golden flesh and creamy texture, which makes them perfect for grilling.
Or you can just go with whatever type of potato you have on hand!
How to make Grilled Potatoes in Foil Packets:
I like to season my potatoes with garlic powder, onion powder, parsley, salt, and pepper.
The first thing I did was added 1/4 teaspoon of garlic powder, onion powder, parsley, and salt to a small bowl. I also added 1/8 teaspoon of pepper and mixed it together.
Dice the potatoes and onion.
I made two foil packets so I sprayed two pieces of aluminum foil with cooking spray or olive oil spray.
Each piece of foil was about 12 inches long. You want to make sure they are large enough to comfortably wrap the potatoes.
Add the potatoes and onion to the aluminum foil, then add the seasoning mixture.
Bring the edges together and fold them over. Once sealed you can add them to your preheated grill. Cook 20-30 minutes or until they are fork tender.
Serving and Garnishing Grilled Potatoes:
Once your grilled potatoes are cooked to perfection, it’s time to serve and garnish them for a truly mouthwatering dish. Here are some serving and garnishing ideas that will take your grilled potatoes to the next level:
- Fresh Herbs: Sprinkle your grilled potatoes with freshly chopped herbs like parsley, chives, or rosemary for a burst of flavor and a beautiful pop of green.
- Cheese: Add a sprinkle of grated cheese such as cheddar, Parmesan, or feta on top of your grilled potatoes while they’re still hot. The cheese will melt and create a deliciously gooey topping. Just be sure to add any WW points.
- Sour Cream or Greek Yogurt: Serve your grilled potatoes with a dollop of sour cream or Greek yogurt on the side. The creamy and tangy flavors will complement the smoky potatoes perfectly.
- Bacon Bits: For a crispy and savory twist, sprinkle some bacon bits on top of your grilled potatoes. The combination of the smoky potatoes and crispy bacon is simply irresistible. Again, calculate the WW points.
- Scallions or Red Onions: Thinly slice scallions or red onions and scatter them over your grilled potatoes. The mild onion flavor adds a nice crunch and extra layer of taste.
- Dips and Sauces: Serve your grilled potatoes with a variety of dips and sauces such as aioli, ranch dressing, or barbecue sauce. These condiments will enhance the flavors and provide a satisfying dipping experience.
Calculating the WW Points:
The points for this recipe come from the potatoes. The most accurate way to calculate the points is by using a food scale to weigh the potatoes.
My potatoes weighed 14 ounces, which is 9 points. I made four servings so it was 2 points per serving according to the WW app.

Yield: 4 servings (I used 14 ounces of potatoes, which was 9 points, making this recipe 2 points per serving)
- 14 oz. potato of choice, diced (doublecheck the points for your potato)

- 1/4 teaspoon garlic powder
- 1/4 teaspoon onion powder
- 1/4 teaspoon parsley

- 1/8 teaspoon pepper
- Aluminum foil and olive oil spray
-
Preheat the grill.

In a small bowl mix together the garlic powder, onion powder, parsley, salt, and pepper.
-
Use aluminum foil pieces large enough to comfortably wrap the potatoes. Spray the aluminum foil with olive oil spray so the potatoes don't stick.
-
Add the potatoes and onion to the aluminum foil, then sprinkle on the seasoning mixture.
-
Bring the edges of the foil together and fold over. Once sealed you can add the potatoes to your preheated grill. Cook 20-30 minutes or until the potatoes are fork-tender.
