Philly Cheese Steak Foil Packet Dinners

Philly Cheese Steak Foil Packet Dinners

Philly cheesesteak foil packet dinners are an all-in-one grilled dinner with steak, peppers, onions, mushrooms, and melted provolone sealed in heavy-duty foil. The packets steam as they grill, so everything turns tender and the cheese melts right over the filling for a steaming-hot bite.

Ingredients

Steak filling

1.5 lb sirloin steak Thinly sliced for quick grilling.
2 bell peppers Slice into strips.
1 onion Slice into rings or half-moons.
2 cup mushrooms Slice so they grill evenly.
8 provolone cheese Cut into slices.
2 tbsp Worcestershire sauce
2 tbsp olive oil
1 tsp garlic powder
0.25 Salt and pepper to taste Season to your preference.

Serving (optional)

Hoagie rolls Serve hot, or skip for a low-carb style.

Equipment

1 sheet pan

Method

Assemble the foil packets

Divide the thinly sliced sirloin steak, sliced bell peppers, sliced onion, and sliced mushrooms among 4 heavy-duty foil sheets.
Drizzle each packet with olive oil and Worcestershire sauce.
Season each packet with garlic powder, salt, and pepper.
Top each packet with 2 slices provolone cheese.
Fold the foil into sealed packets, crimping the edges tightly to keep steam inside.

Grill and finish

Grill the foil packets over medium heat for 18-20 minutes, flipping halfway through cooking.
Carefully open the packets and serve hot in hoagie rolls, or serve as-is.

Notes

Pro tip: Slice the steak thinly so it cooks through during the 18-20 minute grill time—cheese melting is best once the packets are steaming hot. Refrigerate leftovers in a sealed container for up to 3 days; reheat in a skillet until steaming. Freezing isn’t recommended because the provolone can change texture. Dietary swap: use a low-sodium Worcestershire sauce if you’re watching sodium.
