How to Make Steak and Onion Foil Packets
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Tear four large sheets of heavy-duty aluminum foil.
Step 2: Build the Packets
Place a layer of sliced potatoes in the center of each foil sheet. Season lightly with salt and pepper.
Set one steak on top of the potatoes, then pile sliced onions over the steak. Season again with salt and pepper.
Step 3: Seal
Fold the foil up and over the ingredients, sealing tightly to create a packet. Make sure there’s a little space inside for steam.
Step 4: Bake
Place foil packets on a baking sheet and bake for 45–55 minutes, depending on steak thickness and desired doneness.
Step 5: Serve
Carefully open packets (steam will be hot). Serve straight from the foil or transfer to plates.
