Ultimate Chicken Avocado Melt Sandwich

Some afternoons, the kitchen feels like the perfect place to pause the rush of the day. I remember opening the fridge, spotting ripe avocados on the counter, and a loaf of sourdough nearby.

The thought of making a sandwich turned into a small experiment, a way to turn simple ingredients into something satisfying and cozy. I cooked the chicken until it was golden, still juicy inside, and layered it with creamy avocado, crisp red onion, and ripe tomato.

The heat of the pan transformed the cheese into a gooey blanket that held everything together. As the bread sizzled in the skillet, the aroma of butter and toasted sourdough filled the air, signaling something hearty was on its way.

Tools Needed

Cooking Instructions

Step 1: Cook the Chicken

Season the chicken breasts generously with salt and pepper. Heat olive oil in a skillet over medium high heat. Cook the chicken for 6–7 minutes per side until golden brown and fully cooked to 165°F (74°C). Let rest for 5 minutes, then slice thinly.

Step 2: Prepare the Vegetables and Cheese

Slice avocado, tomato, and red onion. Keep the cheese ready to layer.

Step 3: Spread the Condiments

Mix mayonnaise and Dijon mustard together. Spread evenly on all four slices of bread.

Step 4: Build the Sandwich

On two slices of bread, layer chicken slices, avocado, cheese, onion, and tomato. Top with the remaining bread slices, mayo side down.

Step 5: Grill the Sandwich

Heat a skillet or grill pan over medium heat. Add butter or olive oil, then place the sandwiches in the pan. Cook for 3–4 minutes per side, pressing gently with a spatula, until bread is golden and cheese is melted.

Step 6: Serve

Remove from heat, let rest for one minute, slice in half, and serve warm.

Mistakes to Avoid & Solutions

Mistake 1: Chicken too dry

Solution: Cover the skillet with a lid for the last minute of cooking to help cheese melt evenly.

Mistake 4: Overcrowding the sandwich
Solution: Layer ingredients evenly too much filling makes it hard to grill properly.
