Grilled Zucchini and Squash in a Foil Packet

It doesn’t get any easier than zucchini on the grill in foil! It’s my favorite simple summer side dish recipe because I can put it together in less than ten minutes! All that’s left is throwing it on the grill with my meat! Clean-up is incredibly simple too!

Ingredients

  • 4 small zucchini
  • 1/4 cup onion optional
  • 1/4 teaspoon season salt
  • 1/4 teaspoon pepper
  • 3 Tablespoons butter
  • 1 Tablespoon parmesan cheese optional

Instructions

  • Cut zucchini and yellow summer squash into slices about 1/4 inch thick. Try and keep them even in size so they'll cook evenly. You don't need to peel them first.
  • Place zucchini and onions on a piece of heavy-duty aluminum foil, or a double layer of regular aluminum foil. Make sure the foil is big enough for the zucchini to be spread out no thicker than a triple layer. You don't need to arrange them, you just don't want the packet to be too thick. Make sure the foil is big enough to create a packet.
  • Add sliced onion, tomatoes, eggplant, or herbs if you'd like.
  • Sprinkle with season salt and pepper. Cut butter into slices and set on top of veggies.
  • Bring edges of the packet up and fold over three times to seal. Fold edges to seal.
  • Place packet on the heated grill (I put them on the grill when I put my meat on the grill). Continue cooking zucchini for about 12 minutes. See the chart below for cooking time and temperature suggestions.
  • Remove from the grill and leave the packet closed for a couple minutes to let it steam. Be careful when opening the packet because steam will escape.
  • Top with chopped herbs and grated parmesan cheese if desired

Notes

Cooking time will vary depending on the thickness of the veggies, the packet, and the grill temperature. I always grill my zucchini packs right alongside my meat, at whatever temperature the meat is cooking. You can adjust cook time according to this chart.
  • 350 degrees 15-17 minutes
  • 375 degrees 12-15 minutes
  • 400 degrees 10-12 minutes
  • 425 degrees 8-10 minutes
Zucchini will continue to cook after you take it off the grill, so if you aren't serving it right away you'll want to shorten cook time by a couple of minutes.
