Ingredients Equipment Method Notes

Ingredients
  

  • 4 boneless chicken breasts Pounded thin for even cooking.
  • 2 avocados Ripe, sliced.
  • 8 bacon Cooked crispy.
  • 8 Swiss cheese Slices.
  • 8 sourdough or ciabatta bread Sliced.
  • 2 tbsp butter For buttering the bread and toasting.
  • 1 tbsp olive oil For cooking the chicken.
  • 1 tsp garlic powder Seasoning for the chicken.
  • 1 salt and black pepper To taste for the chicken seasoning.
  • 1 Dijon mustard and mayonnaise Spread to balance tangy and creamy flavors.

Equipment

  • 1 cast iron skillet

Method
 

Cook the chicken
  1. Pound the boneless chicken breasts thin, then season them with garlic powder, salt, and black pepper.
  2. Heat olive oil in a cast iron skillet over medium-high heat, then cook the chicken for 5–6 minutes per side until cooked through with no pink in the center.
Assemble and toast the sandwiches
  1. Butter the outside of all bread slices so the crust toasts evenly.
  2. Spread Dijon mustard on the unbuttered side of half the bread slices and mayonnaise on the unbuttered side of the remaining bread slices.
  3. On the Dijon side, layer Swiss cheese, the cooked chicken, avocado slices, and crispy bacon, then close each sandwich with the buttered-side out.
  4. Toast in the cast iron skillet over medium heat for 3–4 minutes per side, until the bread is golden and the Swiss cheese is fully melted.
Serve
  1. Slice each sandwich diagonally and serve immediately while the cheese is still pulling.

Notes

Pro tip: use fully crispy bacon and pounded-thin chicken so the melt happens by the time the bread turns golden. Refrigerate leftovers in an airtight container up to 3 days; reheat in a skillet to keep bread crisp. Freezing isn’t recommended because avocado texture changes after thawing. Dietary swap: for a lighter option, replace mayonnaise with Greek yogurt and use turkey bacon if desired (still layer and toast the same way).
