Cowboy Butter Chicken Sandwich (Airfryer)

Serving Size: 2 sandwiches

Protein: ~38–40g per sandwich

Cowboy butter started as a bold, buttery dipping sauce served with grilled steak, loaded with garlic, lemon, mustard, herbs, and spice. It’s rich, punchy, and built for big flavor.

This version keeps that same flavor profile but adapts it for a next-level chicken sandwich.

Instead of melted butter, we use light mayo to create a creamy cowboy butter marinade that sticks to the chicken and builds a flavorful coating as it cooks in the air fryer. With fresh chopped parsley, onions, and layered dry seasonings, the marinade develops a deep, savory crust without any breading.

Finished with a crisp cucumber and cabbage salad and a hit of fresh chives on toasted ciabatta bread, this cowboy butter chicken sandwich is creamy, herby, tangy, and balanced in every bite.
