Ingredients

2 Zucchini
2 Yellow squash
⅛ cup Onion chopped (Optional)
1 tbsp Creole seasoning Slap Ya Mama is our favorite. Tony Chachere is another good one.
3 tbsp Butter Sliced into 6 pats of butter
1 tbsp Parsley chopped
⅙ cup Parmesan shredded or grated (Optional)

Instructions

Preparing Zucchini and Squash in Foil

Chop zucchini and squash into 1/4 inch disks. Chop onion (if using) and add all vegetables to medium mixing bowl.
Sprinkle seasoning over vegetables in bowl and toss to coat veggies evenly.
Spread vegetables on one large sheet of foil. (Foil must be large enough to fold back over the top of the vegetables and seal well around the three open edges. If this is not possible, you can always place a second sheet on top of the vegetables and very carefully seal up all the sides.)
Spread around 6 pats of butter over the top of the vegetables.
Seal the foil packet.

Grilling Zucchini and Squash in Foil

Place packets on the top rack over medium heat on a gas or charcoal grill for 15 -20 minutes, flipping once. Vegetables should receive indirect heat. Keep sides of grill rack pulled up to retain heat. (You can grill meat on the lower rack at the same time, if desired. If you need to crank the heat up, the vegetables will not need as much cook time. Reduce by 2-3 minutes. If you are reducing the heat, you may need to add a few minutes cook time.)

Making Oven Baked Zucchini and Squash in Foil (Alternate Method)

Place large foil packet in a single line on an ungreased cookie sheet with rims. Bake for 25 minutes in a pre-heated 375 oven. Zucchini and squash should be mostly soft and tender.
When serving the vegetables from the grill or the oven, be careful while opening as steam will be intense and corn will be hot.

Notes

*Note - There are two different cook times listed in the recipe card - the grill time and the alternate oven time. The oven time will take longer than the grill time.

*Undercooking will result in firm squash and zucchini. Overcooking will result in crispy vegetables that may lack flavor. Keep an eye out for your preferred doneness!
