30 Minute Buttery Grilled Potatoes in Foil

Grilled in foil packets is my favorite way to cook potatoes! The thinly sliced potatoes — Yukon gold or russet potatoes work well — emerge from the foil packet extra buttery and perfectly seasoned after just 30 minutes on the grill.These sliced potatoes are the perfect summer side dish!

Equipment

  • Grill
  • Grilling Spatulas
  • Aluminum Foil

Ingredients

  • 3 pounds Yukon gold potatoes
  • ½ cup butter
  • 1 tablespoon kosher salt
  • Freshly cracked black pepper
  • 2 tablespoon minced garlic
  • ½ cup diced white onion
  • ¼ cup olive oil

Instructions

  • Scrub the potatoes well to be sure the skin is clean. (If using Russets, peel the potatoes.)
  • Slice potatoes into rounds about ¼ of an inch thick and set aside.
  • Using a cold stick of butter, create a thin layer of butter in the center of two 18x12 inch pieces of foil. The tracings of butter should measure approximately 12x9 inches.
  • Place half of the sliced potatoes in a thin, even layer on top of one of the butter rectangles. Season with half of the salt and a generous sprinkling of freshly cracked black pepper. Top with 1 tablespoon of garlic and ¼ cup of the onion. Place 4 – 6 pats of butter on top of this first layer of butter.
  • Repeat the process of layering and seasoning with the remaining potatoes directly on top of the first layer. Drizzle the entire dish with olive oil.
  • Top with the second piece of foil and fold all the edges in toward the center twice to create a sealed packet.
  • Grill over medium-high heat for 15 – 20 minutes on the first side before flipping and grilling for another 10 – 15 minutes. (Longer for crispier potatoes.) The packet will puff up during the cooking process – this is ok!
  • Remove potatoes from grill and allow foil to cool a few minutes before opening packet. Sprinkle with fresh parsley or chives before serving, if desired.

Notes

  • Leftover potatoes can be stored in the fridge for up to five days. (And make a really great breakfast!)
