how to cook in packets

Steaming food in the oven in folded packets of parchment paper (or foil) is a great way to keep food juicy and tender. As the food heats up in the packet, it creates steam, which gently cooks the food and prevents it from drying out. Follow these easy step-by-step instructions for making packets for the oven. Or, if you're grilling, check out our tips on making foil packets for the grill.

Step 1. Fold Parchment Paper or Foil

Step 1. Fold Parchment Paper or Foil

Start with four 20- to 24-inch-long pieces of parchment paper or foil. Fold in half crosswise.

Step 2. Cut Out a Heart Shape

With the parchment or foil folded, draw half a heart shape on one side as you would if you were making a Valentine. Use scissors to cut out the heart shape.

Step 3. Open Up the Heart

Step 4. Open Up the Heart

Open up the parchment paper or foil heart on your work surface to begin filling the paper packet or foil packet.

How to Make Foil Packets for the Grill

Foil Packets

Cooking in packets is great for the grill, but it's not safe to put parchment paper over an open flame, so use foil.

Step 1: Add Fillings

step 1 for making foil packets

To prepare packets for grilling, start with eight 20- to 24-inch-long pieces of foil. Layer two sheets for each of four packets (the double layers will help protect the contents from burning). Arrange the ingredients on one half of each double layer.

Step 2: Fold the Edges

step 2 for making foil packets

Fold the foil over the ingredients and crimp the edges together.

Step 3: Seal the Ends

step 3 for making foil packets

Fold and crimp both ends to tightly seal the ingredients in the packet.

To cook: Grilling temperatures and times will vary by recipe, but generally you'll want to heat your grill to medium-high or high heat. For seafood packets, grill for about 10 to 12 minutes on one side, or until cooked through. For all other proteins, grill about 20 minutes, flipping halfway through. When cooking packets on the grill, rotate them to another spot on the grill about halfway through to ensure even cooking.
