Prep the Zucchini: Start by washing the zucchini and trimming off the ends. Slice the zucchini lengthwise into strips about 1/4 inch thick. This thickness allows the zucchini to cook quickly and get a nice char without becoming too soft.

Season the Zucchini: Place the sliced zucchini in a bowl. Drizzle with olive oil and toss to coat evenly. Season with salt, black pepper, and garlic powder (if using) to taste. Ensure each slice is well-coated with the oil and seasoning for the best flavor.

Preheat the Griddle: Heat your Blackstone Griddle to medium-high heat. A properly heated griddle is crucial for getting those beautiful grill marks and a nice sear on the zucchini.

Grill the Zucchini: Once the griddle is hot, lay the zucchini slices in a single layer. Don’t overcrowd the griddle to ensure even cooking. Grill for about 3-4 minutes on each side, or until they are tender and have nice grill marks.

Add Finishing Touches: After flipping the zucchini, you can sprinkle grated Parmesan cheese over the slices for added flavor. The cheese will melt slightly, adding a savory, cheesy element to the dish.

Serve: Once the zucchini is cooked, remove it from the griddle. If desired, finish with a squeeze of fresh lemon juice and a sprinkle of fresh herbs like chopped basil or parsley for an extra burst of flavor.

Enjoy: Serve the grilled zucchini as a side dish with your favorite meals. It pairs wonderfully with grilled meats, fish, or as part of a vegetarian spread.
