Step 1: Preheat your oven to 375°F (190°C) and line two large baking sheets with parchment paper for easy cleanup.
Step 2: Cut each pita round into 8 even triangles using a pizza cutter or sharp knife. If using pocket pita, you can gently pull the two layers apart to create thinner, crispier chips.
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 until every piece is lightly and evenly coated with the oil mixture.
Step 5: Spread the pita triangles 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.
Step 7: Remove from the oven and let the homemade baked pita chips cool on the pan for at least 5 minutes to fully crisp up before serving.
