Ingredients
  

Chicken Caesar Croissant Sandwich Ingredients
  • 2 large (4 oz / 115g) butter croissants Sliced horizontally
  • 1 lb (450g) boneless, skinless chicken breasts
  • 1 tbsp (15ml) olive oil
  • 1 tsp (5g) kosher salt
  • 1/2 tsp (2.5g) cracked black pepper
  • 1 cup (47g) romaine lettuce Freshly chopped
  • 1/2 cup (120ml) mayonnaise
  • 2 tbsp (30g) grated Parmesan cheese
  • 1 tbsp (15ml) fresh lemon juice
  • 1 tsp (5g) Dijon mustard
  • 1 clove garlic Minced
  • 1 tsp (5g) freshly cracked black pepper
  • 1 tbsp (3g) fresh parsley Finely chopped

Equipment

  • 1 Cast iron grill pan Used for searing the chicken breast.
  • 1 Sharp serrated bread knife Crucial for slicing the croissant without crushing it.

Method
 

Making the Sandwich
  1. In a small mixing bowl, combine the mayonnaise, grated Parmesan, lemon juice, Dijon mustard, and minced garlic. Whisk until smooth, then fold in the freshly chopped parsley and cracked black pepper.
  2. Preheat a grill pan with olive oil over medium-high heat. Season the chicken with salt and pepper, and cook for 6-7 minutes per side until golden-brown and the internal temperature reaches 165°F (74°C).
  3. Transfer the chicken to a cutting board and let it rest for 5 minutes. Slice thinly against the grain.
  4. Using a sharp serrated knife, carefully slice the croissants in half horizontally without crushing the delicate layers.
  5. Spread the creamy herb Caesar dressing onto the bottom halves of the croissants. Layer with crisp romaine lettuce and the sliced grilled chicken. Top with the remaining croissant half and serve.

Notes

Do not skip the resting phase for the chicken to ensure a perfectly juicy filling.
Always use a serrated knife to cut the croissants to maintain their flaky texture.
