- 2 tablespoons olive oil
- Salt, to taste

Tips for Best Ingredients
Choose firm zucchini and squash with smooth skin and uniform size. Avoid any with soft spots or blemishes. Organic options reduce pesticide exposure but conventional work fine if washed thoroughly.
Step-by-Step Instructions
Step 1 Prep Vegetables
Start by washing zucchini and squash under cold water. Trim both ends carefully. Then, slice each lengthwise into -inch thick strips for even cooking.
No peeling is necessary; the skin crisps nicely on the grill. This zucchini squash grilling technique helps retain shape and speeds cooking without sogginess.
Step 2 Preheat and Season
Preheat your gas grill to medium-high heat, about 400F. While it warms, brush each veggie slice gently but evenly with olive oil on both sides.
Season with salt and pepper to taste. The oil prevents sticking and promotes golden grill marks. This direct grilling method for squash creates edges that sizzle and crisp nicely.
Step 3 Grill the Veggies
Place zucchini and squash directly on grill grates or inside a grill basket if preferred. Grill for 45 minutes per side. Turn once with tongs when edges start to brown and a slight char forms.
Keep the grill lid closed to maintain heat and encourage fast cooking. The veggies should be tender but still hold firmness and vibrant color.
Step 4 Finish and Serve
Remove the grilled vegetables from heat carefully. For extra brightness, drizzle with fresh lemon juice or a bit more olive oil. Avoid adding pepper immediately after grilling to preserve its flavor.
Serve warm as a side dish or incorporate into salads, pastas, or grain bowls.
Step 5 Storage
Allow grilled zucchini and squash to cool completely before storing. Place in an airtight container in the fridge for up to 4 days.
For longer storage, freeze in a single layer on a parchment-lined tray for 23 hours, then transfer to sealed freezer bags for up to 2 months. Thaw overnight in the refrigerator, then reheat gently.

Variations & Substitutions
Flavor Twists
Try sprinkling garlic powder, smoked paprika, or fresh chopped herbs like thyme or basil on the veggies before grilling. These additions intensify flavor without complicating prep.
For a tangy touch, coat the slices in a light balsamic glaze once off the grill.
Vegetable Alternatives
Swap zucchini or squash with eggplant or bell peppers for variety. These vegetables have similar grilling times and pair wonderfully with the basic technique.
Adjusting Seasonings
If you prefer a lighter taste, grill without oil and brush slices afterward just before serving. Adjust salt amounts or try lemon zest for gentle seasoning.
Storage & Shelf Life
Refrigeration
Store grilled zucchini and squash in a sealed container for 34 days. Avoid stacking slices tightly to prevent moisture buildup and soggy grilled zucchini.
Freezing
Freeze the grilled slices flat on a parchment-lined tray for 23 hours. Then transfer to airtight freezer bags. They keep well up to 2 months.
Thaw in the refrigerator overnight before reheating gently on the grill or stovetop.
Make-Ahead Tips
Double or triple the recipe to batch cook for the week. Label containers with the preparation date for easy rotation. Reheat slowly on low heat to maintain texture.

Pro Tips & Troubleshooting
Use Tongs, Not Forks
Flipping with tongs avoids piercing veggies, keeping juices inside. This preserves juiciness and caramelization during grilling.
Apply Oil Evenly
Brush olive oil thoroughly but lightly. Uneven oil can cause flare-ups that burn parts of the veggie and leave others pale or bland.
Check Grill Temperature
If your zucchini and squash lack golden grill marks and flavor, the grill is likely not hot enough. Preheat to at least 400F for perfect caramelization.
Brighten Flavors with Lemon
A quick squeeze of fresh lemon juice just before serving elevates flavors and balances any bitter notes, giving a fresh, tangy finish.
Avoid Soggy Grilled Zucchini
Slice veggies evenly and moderately thin to prevent excess moisture release. Use direct heat and avoid overcrowding the grill.
