Instructions

Preheat grill or oven to 400°F (200°C).
Cut 4 large sheets of heavy-duty foil (about 12×18 inches each) and brush or spray with melted butter.
Layer thinly sliced potatoes and leeks on each foil sheet. Sprinkle with Gruyère cheese, thyme, rosemary, and minced garlic. Season with salt and pepper.
Drizzle ¼ cup of heavy cream over each packet and add a touch of melted butter on top.
Seal each foil packet tightly by folding and crimping the edges to trap steam.
Cook packets on the grill over medium-high heat with the lid closed for 30–35 minutes, or bake on a sheet tray in the oven for 35–40 minutes.
Carefully open packets—watch out for steam—and garnish with chopped parsley or chives before serving.

Notes

Open the packets and broil for 2–3 minutes after cooking for a crisp, golden top.
Swap Gruyère with sharp white cheddar, Emmental, or mozzarella.
Toss sliced figs or zucchini into the layers for added depth or nutrition.
