The creamy avocado balances the savory chicken and tangy mustard spread
Melty cheese makes every bite irresistible
Great for picky eaters (and yes, husbands and teenagers count here)

Ingredients You’ll Need

2 boneless skinless chicken breasts (about 1 lb)
Salt and pepper to taste
1 tbsp olive oil
1 ripe avocado, sliced
4 slices cheese (Swiss, cheddar, or provolone)
4 slices bread (sourdough, ciabatta, or your favorite)
2 tbsp mayonnaise
1 tbsp Dijon mustard
1 small red onion, thinly sliced
1 tomato, sliced
1 tbsp butter or olive oil for grilling

Step-by-Step Directions

Cook the Chicken
Season chicken breasts with salt and pepper. Heat olive oil in a skillet over medium-high. Cook chicken 6–7 minutes per side until golden and fully cooked. Rest 5 minutes, then slice thin.
Prep the Good Stuff
Slice avocado, get your cheese ready, and thinly slice the red onion and tomato.
Spread the Love
Mix mayo and Dijon, then spread evenly on each bread slice.
Assemble Like a Pro
On two slices of bread, layer chicken, avocado, cheese, onion, and tomato. Top with remaining bread slices, mayo side down.
Grill to Golden Perfection
Heat a skillet with butter or oil. Cook sandwiches 3–4 minutes per side, pressing gently until the bread is golden and cheese melts.
Serve & Savor
Let cool for a minute (yes, patience is hard here), slice in half, and enjoy warm.

Cooking Tips for the Perfect Melt

Think of this as your “don’t sweat the small stuff” section.

If your chicken isn’t perfectly uniform, pound it a little before cooking. It helps it cook evenly.
No grill pan? A regular skillet works just fine—just press down gently with a spatula for that café-style toastiness.
Don’t skip the resting step for the chicken. If you slice too soon, all the juices will run out, and nobody likes dry meat in a grilled chicken sandwich.
Cheese choice is flexible. Swiss gives tang, cheddar adds sharpness, and provolone makes it super melty.
Want to add some zing? Toss in a few pickled jalapeños or a drizzle of hot sauce.

A Little Backstory

This sandwich actually came about on a lazy Saturday when I had leftover grilled chicken and one lonely avocado staring back at me from the counter. I didn’t want to fuss with making a full dinner, but I also didn’t want another boring salad. The result? A happy accident that quickly became a family favorite.

Now, my kids ask for this avocado melt at least once a week. It’s the kind of meal where I can sneak in some veggies (hello, tomato and onion) while still giving them something gooey and comforting. And honestly, the first time I served it to friends, they swore I had picked it up from a trendy café downtown. I’ll take that compliment any day.

What to Serve with a Chicken Avocado Melt Sandwich

This sandwich is a star on its own, but the right side makes it shine even brighter:

A crisp green salad with lemon vinaigrette for balance
Classic potato chips for that satisfying crunch
Roasted sweet potato fries if you want something heartier
Or, if you’re like me, just a big iced tea and maybe a pickle spear on the side (because a sandwich without a pickle feels incomplete!)

It’s also a great meal to pair with soup—think creamy tomato or chicken noodle for that classic soup-and-sandwich comfort combo.

How to Store Leftovers

Let’s be honest: this sandwich is best eaten fresh, with that cheese still melty and the bread perfectly toasted. But if you do find yourself with extras:

Refrigerate: Wrap the cooled sandwich in foil or plastic wrap. Store in the fridge for up to 2 days.
Reheat: Warm in a skillet over medium heat to crisp the bread back up and re-melt the cheese. Microwaving will work in a pinch, but you’ll lose that crispy texture.
Avocado note: The avocado may brown a little, but it’s still safe to eat. A quick squeeze of lemon juice on the avocado before assembling helps slow that down.

FAQs

Can I use rotisserie chicken instead of cooking chicken breasts?

Absolutely! That makes this already quick sandwich recipe even faster.

Can I make this vegetarian?

Yes—swap the chicken for grilled portobello mushrooms or even thick slices of roasted zucchini.

What’s the best bread for this recipe?

Sourdough is my favorite (it holds up to all the fillings), but ciabatta or even whole wheat works beautifully.

Can I prep this ahead for lunch?

You can prep the chicken and toppings ahead, but assemble and grill just before eating for the best flavor and texture.
