30-Minute Buttery Grilled Potatoes — Garlic-Butter Foil Packets
Baby potatoes tossed in garlic butter and paprika, sealed in a foil packet, and grilled until tender — a 30-minute side that steams in its own butter.

Filed · Daily Upkeep kitchen
Buttery grilled potatoes — halved baby potatoes tossed in melted garlic butter and paprika, sealed in a foil packet, and left on the grill to steam tender in their own butter. No pot to boil, no pan to scrub, one packet to open at the table.
The recipe is right here. Why the sealed packet does all the work, how to know they're done, and the swaps that still taste right live at the bottom.

Ingredients
-
Potatoes
- 2 lb Baby potatoes Halved — keep the pieces roughly the same size so they cook evenly.
-
Garlic butter
- ½ cup Unsalted butter Melted.
- 3 cloves Garlic Minced.
- 1 tsp Salt
- ½ tsp Black pepper
- 1 tsp Paprika Sweet or smoked both work — see notes.
-
Finish
- 1 tbsp Fresh parsley Chopped. Optional, but it wakes the whole packet up.
Method
-
Preheat the grill
T+0:00Get the grill going to medium heat and let it come up to temperature while you prep. Gas or charcoal both work — you want steady, even heat, not a roaring sear zone.
-
Toss the potatoes
T+0:02In a large mixing bowl, combine the halved baby potatoes, melted butter, minced garlic, salt, black pepper, and paprika. Toss until every potato is evenly coated and glossy — the butter is the cooking medium here, so don't leave dry spots.
-
Build the packet
T+0:05Tear off a large piece of heavy-duty aluminum foil, about 18 inches long. Pile the potato mixture in the center — scrape every drop of garlic butter from the bowl in after it — and fold the edges up and over to create a sealed packet. Crimp the seams tight; the seal is what makes this work.
-
Grill the packet
T+0:07Set the foil packet on the preheated grill and close the lid. Cook for 20–25 minutes, turning the packet occasionally with tongs so both sides see the heat and the butter redistributes.
-
Check for tenderness
T+0:27At the 20-minute mark, carefully open a corner of the packet — mind the steam — and test a potato with a knife or fork. It should slide in with no resistance. Not there yet? Reseal the packet and grill another 5–10 minutes.
-
Open, garnish & serve
T+0:30Pull the packet off the grill and open it carefully, letting the steam vent away from you. Sprinkle with fresh parsley if using, and serve immediately — straight from the foil works, and the garlic butter pooled at the bottom is the sauce.
Notes & swaps
Cut everything the same size
The packet cooks as one unit, so the potatoes need to finish as one unit. Halve the small ones, quarter anything golf-ball-sized or bigger, and aim for pieces of roughly equal thickness. A packet of mixed sizes means the small pieces turn to mush while you wait on the big ones.
Baby Yukon golds and baby reds are both great here — thin skins, creamy centers, no peeling. If all you have are full-size potatoes, cut them into 1-inch chunks and expect the timing to land at the long end of the range.
Heavy-duty foil, or double up
Standard foil tears when you turn a packet full of potatoes and hot butter — and a torn packet on a lit grill is a flare-up waiting to happen. Use heavy-duty foil if you have it; if not, double-layer two standard sheets before you build the packet. Either way, seam side up for the first stretch so nothing leaks before the foil has a chance to seal with steam pressure.
Which paprika?
Regular sweet paprika gives color and a mild backbone. Smoked paprika leans into the grill flavor and is the better pick if your grill is gas (charcoal already brings the smoke). For a little heat, swap in half hot paprika, or add a pinch of red pepper flakes to the butter toss.
Variations that hold up
- Herb butter: add a sprig of rosemary or a few thyme sprigs to the packet before sealing; fish them out at the end.
- Parmesan: shower grated Parmesan over the opened packet while the potatoes are still steaming hot so it melts in.
- Lemon: a squeeze over the finished potatoes cuts the butter and brightens everything.
- Onions: a handful of thinly sliced onion tossed in with the potatoes turns silky-sweet inside the packet.
No grill? Oven works
Build the same packet and bake it on a sheet pan at 425°F for 25–30 minutes. You lose a touch of the grill character (smoked paprika helps claw it back), but the steam-in-butter mechanics are identical. The packet also does great over campfire coals — set it on a grate or directly on a bed of embers and turn it more often.
What to serve with it
This is the side that rides along with whatever else is on the grill — steaks, burgers, brats, grilled chicken — and it finishes unattended while you tend the main. The seasoned chicken cutlets from the spicy vodka pasta work just as well grilled alongside the packet, and on a cooler night these potatoes are a natural match for the classic beef stew.
