Ingredients

  • mayonnaise
  • basil pesto
  • boneless skinless chicken breasts
  • extra virgin olive oil
  • salt
  • cracked black pepper
  • slices of swiss cheese
  • green bell pepper
  • baby spinach
  • brioche buns

Substitutions

  • Both store-bought or homemade basil pesto are great options for making the pesto mayonnaise. 
  • You want to use small chicken breasts roughly the same size as the brioche buns. If you only have large chicken breasts, you can slice one in half to make two cutlets and pound them into the desired size. 
  • While the original chicken burger comes with Swiss cheese, feel free to use your favorite sliced cheese like provolone cheese or mozzarella cheese on the sandwich. 
  • The original burger is served on a brioche bun. However, any large burger bun will work. Other options could be focaccia bread, ciabatta rolls, or your favorite bread to make paninis.

Handy tips

This recipe can easily doubled or tripled if you are feeding more than two people.

Be sure to toast your buns! Toasting the buns will help protect the bread from getting soggy once you add the pesto mayonnaise. 

Make sure to pound the chicken into an even thickness. This will ensure the chicken cooks evenly and the edges do not dry. 

Serving Suggestions

Serve with a side of truffle crinkle fries with the leftover pesto mayonnaise to complete the experience. Truffle salt can be found in the spice aisle at the grocery store.

If you have leftovers, store the chicken, mayonnaise, and bell pepper in an airtight container in the refrigerator for up to three days. Only toast the exact number of buns you plan to eat that day. Toasted bread does not store well.
