Grilled Mushrooms and Onions in Foil Onions and mushrooms are sliced, seasoned, and wrapped inside a durable packet of foil, crimped to seal, and placed on the grill. Super easy with big, bold flavor. A fantastic topper for steaks, potatoes, etc.
Preheat an outdoor grill for medium heat.Advertisement
Fold an 18-inch wide piece of aluminum foil so it is square.
Place onions, mushrooms, and garlic in the middle of the foil. Arrange butter pieces on top of vegetables and drizzle with steak seasoning. Bring 4 corners of the foil together in the center, and crimp any open spaces to seal packet.
Place the foil packet on the preheated grill and cook until vegetables are tender, about 45 minutes. Remove from grill, open packet carefully, and serve.
