How to Make the Best Grilled Chicken Sandwich – Step-by-Step

Step 1: Prep the Chicken

1. Slice each chicken breast horizontally to create 4 thinner cutlets.
2. Rub both sides with olive oil, paprika, salt, black pepper, and chili flakes (optional).
3. Let the seasoned chicken sit for 10 minutes at room temperature while you prep the other ingredients.

Pro Tip: This resting time helps the seasoning penetrate and leads to juicier chicken.

Step 2: Grill the Chicken

1. Preheat a grill pan or outdoor grill to medium-high heat.
2. Grill chicken cutlets for 3–4 minutes per side, or until the internal temperature reaches 165°F.
3. Set aside and let rest for 5 minutes.

Cooking Tip: Press gently with tongs to get grill marks without drying it out.

Step 3: Make the Garlic Butter Bread

1. In a small saucepan over low heat, melt the butter with garlic and parsley.
2. Brush both sides of the sourdough slices with the garlic butter.
3. Toast in a skillet or griddle over medium heat until golden and crispy, about 2–3 minutes per side.

Bonus Flavor: Add a sprinkle of grated Parmesan to the butter mix before toasting.

Step 4: Mix the Creamy Spread

1. In a bowl, combine:
   • 2 tbsp mayonnaise
   • 1 tsp Dijon mustard
   • ½ tsp lemon juice
2. Stir until smooth. Adjust with a pinch of salt or extra lemon juice as desired.

Step 5: Assemble the Sandwich

1. Spread the mayo-mustard mixture on all toasted bread slices.
2. Layer in this order:
   • Lettuce leaf
   • Grilled chicken breast
   • Tomato slices
3. Repeat for a double-stack if using all four chicken pieces.
4. Top with the remaining bread slice and gently press.

Pro Tip: Slice diagonally and serve with a pickle or kettle chips for the full sandwich-shop experience.
