Chicken Avocado Melt Sandwich

I discovered this sandwich during a frantic weekday lunch when I was staring down a container of leftover grilled chicken and two avocados that needed to be used immediately. The combination was such a happy accident that I started planning leftover chicken specifically just to make these melts. Something magical happens when warm cheese meets cool, creamy avocado.

Last winter my sister came over unexpectedly, tired and hungry after a long shift at work. I threw these together while she sat at my counter, and she took one bite and went completely silent. Now she texts me whenever she has leftover chicken just to confirm shes making them correctly.

Ingredients

• 2 cups cooked chicken breast: Shredded rotisserie chicken works perfectly here, or use leftover grilled breast. The key is having tender meat thats already seasoned.
• 2 ripe avocados: One gets mashed into the spread for creaminess, the other sliced for fresh texture. They should yield slightly to gentle pressure.
• 4 slices provolone or Swiss cheese: Provolone melts beautifully and adds mild sharpness. Swiss works if you prefer something nuttier.
• 8 slices sourdough bread: Sourdough holds up to grilling without getting soggy, and its tang pairs wonderfully with avocado.
• 1 small tomato: Thinly sliced adds brightness and cuts through the rich cheese and avocado.
• 2 tablespoons mayonnaise: Helps create that creamy spread consistency. Greek yogurt is a lighter swap.
• 1 tablespoon Dijon mustard: Adds just enough sharpness to balance all the creaminess.
• 1 tablespoon fresh lemon juice: Essential for keeping the avocado bright and adding a fresh zing.
• 2 tablespoons unsalted butter: For getting that perfectly golden, crispy exterior. Softened butter spreads more evenly.

Instructions

Mash the avocado spread:

Combine one ripe avocado with lemon juice, mayonnaise, Dijon, salt, and pepper until completely smooth.

Assemble the base:

Spread the avocado mixture on four bread slices, then layer chicken, tomato, remaining sliced avocado, and cheese.

Build and butter:

Top with remaining bread slices, then butter the outside of each sandwich generously on both sides.

Grill to golden perfection:

Cook in a heated skillet over medium heat for 34 minutes per side, pressing gently, until golden and cheese is melted.

These melts have become my daughters requested birthday lunch for three years running. Theres something about that first crunch through toasted bread into warm, cheesy chicken and cool avocado that just makes people happy.

Choosing Your Bread

Ive found that slightly stale sourdough actually grills better than fresh because it holds up to the weight of all those toppings. Whole grain adds a nice nuttiness, but avoid very soft sandwich bread or it will turn mushy.

Make Ahead Strategy

You can prepare the avocado spread up to a day ahead if you press plastic wrap directly onto the surface to prevent browning. Assemble everything just before grilling for the best texture.

Customization Ideas

Sometimes I add crispy bacon or a handful of baby spinach for extra color and nutrition. The recipe is incredibly forgiving and adapts well to whatever you have on hand.

• Add pickled red onions for a bright acidic punch
• Sprinkle Everything Bagel seasoning on the buttered outside before grilling
• Swap chicken for sliced turkey or leave it out for a vegetarian version

Theres nothing quite like a warm, crispy sandwich on a busy day, especially one that comes together this easily.

Recipe FAQs

→ What bread works best for melts?

Sourdough or whole grain bread holds up well to grilling and provides sturdy structure for the hearty fillings.

→ Can I use rotisserie chicken?

Yes, rotisserie chicken works perfectly and saves time. Simply shred about 2 cups from a store-bought rotisserie chicken.

→ How do I know when the cheese is melted?

The cheese should be completely melted and slightly oozing out the sides. The bread will be golden brown and crispy.

→ Can I make these ahead of time?

These are best served fresh and warm. However, you can prep the avocado spread and shred the chicken up to a day ahead.

→ What cheese alternatives work well?

Cheddar, mozzarella, or pepper jack all melt beautifully. Choose based on your flavor preference.

→ How do I prevent the bread from burning?

Keep the heat at medium and monitor closely. Press gently but don't flatten too much, which can cause uneven heating.
