Cook the Pasta: Bring a large pot of salted water to a boil. Add the pasta and cook it according to the package instructions until al dente. Drain and rinse under cold water to stop the cooking process.
Preheat Oven: Preheat your oven to 400°F (200°C).
Prepare Pasta: In a large mixing bowl, combine the cooked pasta, olive oil, minced garlic, grated Parmesan cheese, Italian seasoning, red pepper flakes (if using), salt, and black pepper. Toss well to ensure all the pasta is evenly coated.
Arrange on Baking Sheet: Line a baking sheet with parchment paper. Spread the pasta in a single layer on the baking sheet, ensuring they do not overlap for even crisping.
Bake: Bake in the preheated oven for 15-20 minutes, or until the pasta chips are golden brown and crispy. Keep an eye on them towards the end to avoid burning.
Cool and Serve: Remove from the oven and allow the chips to cool for a few minutes. They will continue to crisp up as they cool.
Garnish: Transfer the chips to a serving bowl and sprinkle with additional Parmesan cheese and fresh parsley for garnish. Serve immediately.
