Jump to RecipeGrilled Chicken Sandwich Ingredients
The Juicy Chicken:
- 4 boneless skinless chicken breasts: Pounded to uniform thickness.
- Brine: 2 quarts cold water, Kosher salt, and 1/4 cup sugar (optional). This ensures the meat stays moist even on a hot grill.
- Cooking Oil: For the grill grates.
The Green Sauce (The Secret):
- 1/4 avocado: Provides creaminess without dairy.
- 1/2 large jalapeño: Seeded for flavor, or leave seeds for heat.
- 1/4 cup cilantro: Fresh leaves and stems.
- Liquids: 5 tbsp vegetable oil, 2 tbsp water, and 1 tbsp lime juice to emulsify.
- Seasoning: Salt and black pepper.
The Assembly:
- 4 sesame burger buns: Classic soft buns work best.
- 6 strips thick-cut bacon: Grilled or pan-fried until crisp.
- 1 cup crushed ruffled potato chips: The hidden crunch factor.
- Toppings: 3/4 cup mayo, 1 cup shredded iceberg lettuce, and 4 tomato slices.

How To Make Grilled Chicken Sandwich
- Prep the Meat: Place chicken breasts between sheets of plastic wrap. Pound them with a meat mallet or rolling pin until they are an even 3/4-inch thickness. This guarantees they cook quickly without drying out.
- Brine (Optional but Recommended): In a large bowl, dissolve 1/4 cup salt and the sugar in the cold water. Submerge the chicken breasts and let them soak for 30 minutes in the fridge. Remove and pat thoroughly dry.
- Blitz the Sauce: In a blender or food processor, combine the avocado, jalapeño, cilantro, vegetable oil, water, lime juice, salt, and pepper. Blend until smooth, bright green, and creamy. Set aside.
- Cook the Bacon: Cook the bacon in a skillet or on a cooler part of the grill until the fat renders and it becomes crispy. Drain on paper towels.
- Grill the Chicken: Preheat your grill (or grill pan) to medium-high heat. Oil the grates. Grill the chicken for about 5–6 minutes per side. Flavor Step: In the last minute of cooking, brush the tops of the chicken generously with some of the green sauce. Cook until internal temp reaches 165°F.
- Toast Buns: Place the split buns cut-side down on the grill for 1 minute until golden and toasted markings appear.
- Assemble: Spread mayo on the bottom bun. Top with a handful of crushed potato chips (press them into the mayo so they stick). Layer on the shredded lettuce, the grilled chicken breast, bacon strips, and a tomato slice. Drizzle with more green sauce. Cap with the top bun.

Recipe Tips
- Chip Choice: Ruffled potato chips (like Ruffles) are sturdier than flat chips and maintain their crunch longer against the juicy chicken and mayo.
- Green Sauce consistency: If the sauce is too thick to drizzle, add another teaspoon of water. It should be like a thick salad dressing.
- Grill Marks: To get professional cross-hatch marks, rotate the chicken 90 degrees halfway through cooking on the first side.
- Don’t Skip the Pound: Chicken breasts are naturally uneven. Pounding them ensures you don’t have a dry thin end and a raw thick end.
What To Serve With Grilled Chicken Sandwich
- Grilled Corn: Since the grill is on, throw some corn cobs on the fire.
- Pasta Salad: A chilled pasta salad contrasts nicely with the hot sandwich.
- Watermelon: Slices of cold melon are the perfect summer side.
- Lemonade: Echoes the lime juice in the sauce.

How To Store Grilled Chicken Sandwich
- Components: Store the grilled chicken, bacon, and sauce separately. The chips must be added fresh.
- Reheat: Warm the chicken in a skillet or microwave. The sauce can be kept in the fridge for 2 days, though it may brown slightly due to the avocado (press plastic wrap onto the surface to prevent this).
- Freeze: Freeze the grilled chicken breasts for up to 2 months. Thaw and reheat for a quick meal.

FAQs
Yes, boneless skinless thighs are excellent for grilling and naturally juicy. You likely won’t need to brine them.
With half a jalapeño, it has a mild kick. To make it completely mild, remove all seeds and white ribs from the pepper, or use a green bell pepper instead.
