Preheat oven to 375°F. Stack 5-6 corn tortillas and cut each into 6-8 equal triangles for even baking.
10 count corn tortillas
Place tortilla triangles in a large bowl. Drizzle with 2-3 tablespoons oil and toss to coat lightly. Add kosher salt, chili powder, or garlic powder if using and mix well.
3 tablespoons vegetable oil, to taste kosher salt, optional chili powder, optional garlic powder
Arrange chips on a baking sheet in a single layer with space between pieces to avoid steaming.
Bake for 7 minutes until edges start to brown and curl slightly. Flip each chip using tongs or spatula for even browning.
Bake for an additional 5-8 minutes until chips are golden and crisp with no soft spots. Remove from oven immediately.
Transfer chips to a wire rack to cool completely and stay crunchy. Drizzle with lime juice if desired after baking.
