Your whole family will love the combination of savory boneless chicken, thinly sliced summer squash, green olives, and sweet cherry tomatoes—the zippy lemon and garlic marinade tastes great on EVERYTHING!

Parchment Packets are customizable!

I’ve been on a parchment packet kick lately, throwing together different proteins, vegetables, and sauces in a tidy paper package, which I then toss into the oven. I don’t normally have a game plan when I assemble these pouches. Instead, I just figure out what’s in my fridge and pantry, and use whatever’s available.

By dinnertime, everyone gets an individual bundle filled with saucy meat and veggies that can be served over cauliflower rice, roasted veggies, or white rice (yes, we eat white rice occasionally without too many issues). These parchment packets are easy to make, and the kids enjoy opening up a new “gift” every night.

Can you make chicken foil packets?

Yes! I like using parchment for these packets because I always have a roll in my kitchen. However, aluminum foil also works and it’s even easier to tightly seal packets made with foil. Warning: Do not use wax paper for these packets because it isn’t heat-safe and no one wants melted wax all over their dinner.

How do you know when the parchment packet is ready?

If this is your first time making parchment packets, it can be hard to know when everything is cooked without opening them up. How do you know if the chicken is safe to eat? Stab the packet with a meat thermometer!

Chicken thighs are harder to overcook (and one of the reasons I prefer using them in this recipe) and they are ready to take out when the temperature in the meatiest part reaches 165°F. If you’re cooking chicken breasts, the finished cooking temperature is about 150°F—and you should start checking the temperature at the 15 minute mark.

No meat thermometer? Designate one packet as the sacrificial lamb and open it up at the 18 minute mark. Cut the piece of chicken to check that it’s cooked through and no longer pink. (Order my favorite meat thermometer for next time!)

Time to make Lemon Garlic Chicken Parchment Packets!

Serves 4

Ingredients:

  • ⅓ cup extra virgin olive oil
  • ¼ cup freshly squeezed lemon juice
  • 2 garlic cloves, minced
  • 1½ teaspoons dried oregano
  • Diamond Crystal brand kosher salt
  • Freshly ground black pepper
  • 4 (6-ounce) boneless, skinless chicken thighs or breasts

  • 1 large shallot, thinly sliced
  • 8 pitted green olives, cut in half
  • 8 cherry tomatoes, cut in half

Equipment:

Method:

Preheat the oven to 450°F with the rack in the middle.

In a large bowl, whisk together the olive oil, lemon juice, minced garlic, oregano, 1 teaspoon Diamond Crystal kosher salt, and ¼ teaspoon freshly ground black pepper.

Grab 4 large sheets of parchment paper, and fold each piece in half. Draw half a heart on each piece of paper so that when you cut them out, you get full hearts.

Fold the other half of each parchment heart on top of the chicken and tightly crimp the edges together, starting at the top-center of the heart. Make sure each packet is tightly sealed by turning and crimping the edges. At the pointed bottom end of the hearts, twist the paper to seal well.

Cook in the oven for 15-20 minutes or until the chicken thighs register an internal cooking temperature of 165°F. (How do you know the temperature without opening the package? Stab the packet with a meat thermometer! By the way, if you’re cooking chicken breasts, the finished cooking temperature is 150°F—and you should start stabbing at the 15 minute mark.)

  2. So excited to say I had both your books delivered yesterday 🥳 stayed up half the night looking at them. I can’t wait to try the recipes. Shame we can’t get some of the ingredients in Scotland like plantain but I’ll make do with what we have.
    Love your blog and recipes 💗

  3. Can the packets be refrigerated after cooking for leftovers? Or should I scale back.for one serving.

    1. You can refrigerate the leftovers! I would just transfer them to a glass container to reheat them.
