Preparation

1. Preheat your grill to medium-high heat.
2. Thread zucchini pieces onto skewers, leaving a tiny bit of space between pieces for even cooking.
3. In a small bowl, stir together melted butter, olive oil, minced garlic, salt, pepper, and chopped herbs. Add lemon juice if desired.
4. Brush the zucchini generously with the garlic butter sauce.

Grilling

1. Place skewers on a clean, oiled grill grate. Grill for about 8 to 12 minutes, turning every 2 to 3 minutes until you see light char marks and the zucchini is tender-crisp.
2. Brush additional garlic butter sauce halfway through grilling and again at the end for a glossy finish.
3. Remove from the grill, sprinkle with fresh herbs and a squeeze of lemon before serving.

Oven Baking (Alternate Method)

1. Preheat the oven to 425°F (220°C) and line a sheet pan with foil.
2. Lay the skewers on the pan or spread zucchini pieces if not using skewers. Bake for 10 to 14 minutes, flipping once.
3. If desired, broil for an additional 1 to 2 minutes for color, monitoring closely.
4. Brush with more garlic butter sauce after baking.

Air Frying (Quick Alternative)

1. Preheat the air fryer to 400°F (200°C).
2. Arrange skewers in the air fryer basket and cook for 7 to 10 minutes, turning once.
3. Brush with sauce after cooking and add extra salt if needed.
