The ideal oven temperature for cooking nachos is 350°F to 400°F (175°C to 200°C).

This range melts the cheese evenly while keeping tortilla chips crispy without burning, as confirmed across multiple recipes and cooking guides.

Why Temperature Matters

Lower temps like 350°F give gentle, even melting over 10-15 minutes, perfect for loaded nachos with meats or veggies. Higher ones near 400°F speed things up to 5-10 minutes but demand watching to dodge charred edges. One outlier video mentions 225°F for 5 minutes with simple toppings, but that's unusually low and risks soggy results.

Quick Baking Steps

  1. Preheat oven to 350-375°F.
  1. Layer chips on a sheet pan, add cheese first to "seal" them, then toppings.
  1. Bake 5-7 minutes until cheese bubbles; add fresh garnishes post-bake.
  1. Broil 1-2 minutes optional for golden crisp.

TL;DR: Bake at 375°F for 10 minutes —melty, crunchy perfection every time.
