• Cut the zucchini into ½-inch cubes for even and quick cooking.
  
• Transfer the diced zucchini to a medium-sized bowl. Add olive oil and season with garlic powder, Italian seasoning, salt, and pepper. Toss them well, so they are all coated with the seasoning.
  
• Preheat the air fryer to 400°F (200°C). Add the seasoned zucchini to the air fryer basket and spread them in a single layer (cook in batches if required).
  
• Air fryer them at 400°F (200°C) for 10-12 minutes or until slightly browned and roasted. Shake the basket halfway through.
  
• Serve the Roasted Zucchini immediately.

Oven Method

• Preheat the oven to 450°F. Transfer the seasoned zucchini to a baking sheet.

  Spread them evenly in a single layer and cook for about 10-15 minutes, or until they are slightly browned and roasted (time may vary based on the size of your cubes). You may have to turn them once halfway through.
