Step 1: Preheat your oven to 375°F (190°C) and line two large baking sheets with parchment paper for easy cleanup.
Step 2: Using a sharp knife or kitchen shears, cut each pita round into 8 equal triangles (like a pizza). If you prefer thinner chips, split the pita pockets in half before cutting into triangles.
Step 3: In a large mixing bowl, whisk together the extra virgin olive oil, sea salt, garlic powder, dried oregano, and black pepper.
Step 4: Add the pita triangles to the bowl and toss thoroughly with your hands or a spatula until every piece of homemade baked pita chips is evenly coated with the oil and spices.
Step 5: Spread the pita pieces in a single layer on the prepared baking sheets, ensuring they do not overlap.
Step 6: Bake for 10-12 minutes, flipping the chips halfway through, until they are golden brown and crispy. Keep a close eye on them as they can go from golden to burnt very quickly.
Step 7: Remove from the oven and let the homemade baked pita chips cool completely on the baking sheet to reach maximum crispness.
