Tips for recipe success

Keep these simple tips in mind for the best texture and flavor.

  • Freshly grated cheese: Grating your own cheese helps it melt more smoothly than pre-shredded blends coated with anti-caking agents.
  • Pre-cut onion: Use pre-cut or frozen diced onion to save prep time.
  • Crush chips correctly: Place tortilla chips in a resealable bag and coarsely crush with a rolling pin or mallet—aim for quarter-inch pieces rather than fine crumbs.
