Tear 4 large sheets of aluminum foil. Lightly drizzle each sheet with olive oil and place 1 tablespoon of butter in the center of each.
02 -
Distribute diced potatoes evenly over the butter on each foil sheet, leaving skins on. Sprinkle minced garlic and diced onion evenly over the potatoes. Season with salt and black pepper, then drizzle with a little more olive oil.
03 -
Place steak chunks on top of the potatoes. Season with additional salt, pepper, and steak seasoning. Drizzle a small amount of olive oil over the meat and place a pat of butter on top. For moisture retention, add a large ice cube on top of the meat in each packet.

Fold the edges of each foil sheet to create a sealed packet, ensuring no juices escape. Preheat the grill to medium-high heat (approximately 350°F). Grill packets for 35 to 45 minutes until potatoes are tender and steak reaches desired doneness, using a meat thermometer if preferred.

Carefully open the foil packets to avoid steam burns. Serve immediately.
