Tips

  • One patty per sandwich here, not two, or you have rebuilt the full size version.
  • Go light on the onions so they season rather than dominate.
  • Griddle both outer sides, never just the top.

Variations

  • Add bacon for smoke against the sweet onions.
  • Swap Monterey Jack for pepper jack to add heat.
  • Use a bun instead of toast for a lighter sandwich.

Serving Ideas

Serve with fries and pickles. A pickle spear cuts the richness of the sauce.
