Step‑by‑Step Instructions for Grilled Zucchini
Step 1: Preheat the Grill
Begin by preheating your grill or indoor grill pan to medium-high heat, around 375°F to 400°F. This ensures that the grill is hot enough to create those beautiful char marks while cooking the zucchini evenly. Let it heat for about 5–10 minutes. A properly heated grill will prevent the zucchini from sticking and promote that delightful smoky flavor.
Step 2: Prepare the Zucchini
While the grill is heating, wash and dry the zucchinis, then slice them into ½-inch thick rounds. In a large mixing bowl, toss the sliced zucchini with olive oil, Italian seasoning, garlic powder, kosher salt, and onion powder. Aim for an even coating, ensuring each slice glistens with oil and spices. This step is essential for achieving the perfect flavor in your grilled zucchini.
Step 3: Grill the Zucchini
With the grill ready, arrange the zucchini slices in a single layer on the grill grates. Cook them for about 2–3 minutes on one side until they look golden brown and slightly charred. Flip them gently using tongs, and cook the other side for another 2–3 minutes. Look for a fork-tender texture, ensuring they remain firm and not mushy for that perfect grilled zucchini experience.
Step 4: Add Lemon and Parmesan
Once your zucchini slices are done grilling, remove them from the grill and transfer them to a serving platter. Immediately squeeze fresh lemon juice over the top, allowing the bright acidity to enhance the flavors. Then, generously sprinkle grated Parmesan cheese across the warm zucchini, letting it melt slightly for irresistible richness and savory notes.
Step 5: Garnish and Serve
For an optional finishing touch, add freshly chopped basil over the grilled zucchini. This adds an aromatic layer to your dish, making it even more inviting. Serve your grilled zucchini immediately while hot, and watch it steal the show as a vibrant, healthy side to complement any summer meal!

Make Ahead Options
Grilled Zucchini is a fantastic choice for meal prep, allowing you to savor the fresh flavors of summer even on the busiest days. You can slice the zucchini and toss it with olive oil and seasonings up to 24 hours in advance, just be sure to refrigerate it in an airtight container to maintain its crunch and flavor. Grilling it fresh before serving ensures that it remains tender yet firm, avoiding any mushiness. When you’re ready to enjoy your dish, simply grill the zucchini for 2-3 minutes per side, and finish with lemon juice and Parmesan for that irresistible taste. Prep ahead and unlock more free time for yourself while still serving a delightful side!
