Tips and Variations:
Slice the Potatoes Evenly
Cutting the potatoes into equal thickness helps them cook evenly and prevents some pieces from becoming undercooked.
Use Different Cheeses
Try mozzarella, cheddar, Monterey Jack, or smoked Gouda for a different flavor while still keeping the potatoes creamy and delicious.
Add More Vegetables
Bell peppers, mushrooms, zucchini, or sliced carrots can be added to create a colorful and heartier foil packet meal.
Boost the Flavor
Fresh herbs like parsley, thyme, rosemary, or chives add freshness and make the finished dish even more aromatic.
Make It a Complete Meal
Add sliced smoked sausage, chicken, bacon, or shrimp to the foil packets for an easy all-in-one grilled dinner.
Use Yukon Gold Potatoes
Yukon Gold potatoes become extra creamy after grilling, while Russet potatoes create a fluffier texture with crisp edges.
Storage
Store leftover grilled onions and potatoes in an airtight container in the refrigerator for up to 3 days.
Freeze for Later
Freezing is not recommended because the potatoes may become soft and grainy after thawing.
