Herb Seasoned Grilled Potatoes

Summer grilling always makes me think of foil packets, and these herb seasoned grilled potatoes are the reason why. The smell of rosemary and garlic hitting a hot grill is enough to make everyone wander over to see what is cooking. I started making these on camping trips years ago and now they show up at nearly every backyard cookout I host. They are simple, forgiving, and somehow always disappear first.

One Fourth of July, I brought these to a potluck and a friend who swore she hated thyme went back for thirds. She still does not believe me when I tell her what was in them.

Ingredients

• 1.5 lbs small Yukon Gold or red potatoes: Cut into one inch pieces so they cook evenly and soak up the herb oil.
• 2 tablespoons olive oil: Coats every piece and helps the seasonings stick while creating a slight crust inside the packet.
• 2 teaspoons fresh rosemary, chopped: Brings a piney warmth that pairs beautifully with grilled flavors.
• 2 teaspoons fresh thyme, chopped: Adds an earthy depth that dried thyme simply cannot match.
• 2 teaspoons fresh parsley, chopped: A bright finish that keeps the potatoes tasting fresh rather than heavy.
• 3 cloves garlic, minced: Melts into the oil and creates a subtle garlicky steam inside each packet.
• 1 teaspoon kosher salt: Draws out moisture and seasons the potatoes from the inside out.
• 0.5 teaspoon freshly ground black pepper: Just enough warmth without overpowering the herbs.
• 2 tablespoons grated Parmesan cheese (optional): Melts into the potatoes during the last few minutes for a savory finish.

Instructions

Get the grill hot:

Preheat your grill to medium high, around 400 degrees Fahrenheit, so the potatoes get a good sear through the foil.

Toss everything together:

In a large bowl, combine the potato pieces with olive oil, rosemary, thyme, parsley, garlic, salt, and pepper, tossing with your hands until every piece glistens.

Build your packets:

Tear two large sheets of heavy duty foil, divide the potatoes between them in a single layer, then fold and crimp the edges tightly to seal in all that steam and flavor.

Grill until tender:

Place the packets on the grill grates and cook for twenty to twenty five minutes, flipping once halfway through, until a fork slides through the potatoes easily.

Open carefully and serve:

Watch for the burst of hot steam when you open the packets, then sprinkle with Parmesan and extra herbs if you like before serving right away.

There is something about opening a foil packet at a picnic table that feels like unwrapping a small gift. People lean in every time.

Making It Your Own

I have tossed in sliced onions, bell peppers, and even chunks of smoked sausage when I wanted this to stretch further as a main dish. The foil packet technique is endlessly adaptable so treat the seasonings as a starting point and follow your cravings.

No Grill, No Problem

A four hundred twenty five degree oven works just as well if the weather turns or you do not feel like firing up the grill. Bake the packets on a sheet pan for twenty five to thirty minutes and you will get nearly identical results with even less effort.

Fresh Herbs Versus Dried

Fresh herbs make a noticeable difference here, but dried will work in a pinch if you use one third of the amount called for.

• One teaspoon each of dried rosemary, thyme, and parsley is the right substitute.
• Rub dried herbs between your palms before adding to wake up the oils.
• Taste a potato before serving and adjust salt because dried herbs can sometimes dull the seasoning.

Save Pin

Keep a few extra sheets of foil handy because someone always asks to take a packet home.

Recipe Questions & Answers

→ What size and type of potatoes work best?

Small Yukon Gold or red potatoes are ideal because they hold shape and cook evenly. Cut into 1-inch pieces so they cook through in 20–25 minutes on the grill.

→ How hot should the grill be and how long to cook?

Preheat to medium-high, about 400°F (200°C). Grill foil packets for 20–25 minutes, turning once halfway, until potatoes are tender and edges show light browning.

→ Can I substitute dried herbs for fresh?

Yes. Use about one-third the amount of dried herbs: roughly 1 tsp each of dried rosemary, thyme and parsley. Add them to the oil so they rehydrate during cooking.

→ How do I prevent soggy potatoes or get more browning?

For more browning, open packets for the last 3–5 minutes of grilling and place directly on grates or move to a hotter spot. Avoid overcrowding pieces so steam can escape and surfaces can brown.

→ Can these be prepared ahead and reheated?

Yes. Assemble and chill sealed packets up to a day ahead. Reheat on the grill over medium heat for 10–15 minutes or bake at 350°F until warmed through, then finish open for a few minutes to refresh browning.

→ What serving ideas pair well with these potatoes?

They pair with grilled meats, roasted vegetables, or a fresh green salad. Finish with grated Parmesan, extra herbs, or a squeeze of lemon for brightness.
