Grilled zucchini slices are a simple yet delicious way to enjoy this versatile vegetable. Perfect as a side dish or a light main course, these slices are seasoned with a blend of olive oil, garlic powder, and Italian seasoning before being grilled to perfection. The result is a smoky, tender, and flavorful dish that pairs well with a variety of meals.
Most of the ingredients for this recipe are common pantry staples, but if you don't usually keep Italian seasoning on hand, you might need to pick some up at the supermarket. This blend typically includes herbs like basil, oregano, and thyme, which add a wonderful depth of flavor to the zucchini slices.

Ingredients For Grilled Zucchini Slices Recipe
Zucchinis: Fresh and firm, these are the star of the dish, providing a mild flavor and tender texture when grilled.
Olive oil: Adds a rich, fruity flavor and helps the zucchini slices to cook evenly without sticking to the grill.
Salt: Enhances the natural flavors of the zucchini and the seasonings.
Pepper: Adds a touch of heat and complexity to the dish.
Garlic powder: Provides a subtle, savory garlic flavor that complements the zucchini.
Italian seasoning: A blend of dried herbs that adds a burst of Mediterranean flavor to the zucchini slices.
Technique Tip for This Recipe
When preparing zucchini for grilling, ensure the slices are evenly cut to about ¼ inch thick. This uniformity helps them cook evenly and prevents some pieces from becoming too mushy while others remain undercooked. Additionally, after tossing the zucchini slices with olive oil and seasonings, let them sit for a few minutes to allow the flavors to meld. This brief marination enhances the overall taste once grilled.

- For longer storage, consider freezing. Lay the zucchini slices in a single layer on a baking sheet lined with parchment paper.
- Freeze the slices for about 1-2 hours, or until they are solid. This prevents them from sticking together.
