Why You’ll Love This Recipe

I can have this sandwich on the table in just 30 minutes, making it my go-to for busy weeknights.
I adore how the creamy avocado softens the savory chicken, and how the cheese stretches with every bite.
I appreciate the flexibility—I swap breads, cheeses, or veggies based on what’s in my pantry.
I find it equally delightful for lunch, brunch, or a light dinner, and it pairs beautifully with salads or soups.

ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

2 boneless skinless chicken breasts
Salt and pepper, to taste
1 tablespoon olive oil
1 avocado, sliced
4 slices cheese (Swiss, cheddar, or provolone)
4 slices bread (sourdough, ciabatta, or your choice)
2 tablespoons mayonnaise
1 tablespoon Dijon mustard
1 small red onion, thinly sliced
1 tomato, sliced
Butter or olive oil for grilling

directions

Season and cook the chicken. Pat the chicken breasts dry, season both sides with salt and pepper, and heat the olive oil in a skillet over medium-high heat. Cook for 6–7 minutes per side, until no longer pink. Remove from heat and let rest for a few minutes, then slice thinly.
Prep the bread. Spread mayonnaise on two slices of bread and Dijon mustard on the other two slices.
Assemble the sandwiches. On the mayo-coated slices, layer sliced chicken, avocado, cheese, red onion, and tomato. Top each with the mustard-coated slice, mustard side down.
Grill to perfection. Heat a clean skillet or grill pan over medium heat, add a little butter or olive oil, and place the sandwiches in the pan. Cook 3–4 minutes per side, pressing gently with a spatula, until the bread is golden and the cheese is melted.
Rest and serve. Remove sandwiches from the pan, let them rest for a minute, then slice in half and serve warm.

Variations

I love to mix things up with these twists:

Rotisserie chicken: I shred leftover rotisserie chicken for an even quicker prep.
Spicy kick: I swap Dijon for chipotle mayo or add a few dashes of hot sauce.
Veggie boost: I tuck in baby spinach, arugula, or roasted peppers for extra color and nutrients.
Cheese swap: I try pepper jack for heat, mozzarella for mildness, or feta for tang.
Bread choices: I sometimes use whole-grain, gluten-free, or ciabatta rolls for a different texture.

storage/reheating

I store any leftover halves in an airtight container in the fridge for up to 2 days. To reheat, I preheat my toaster oven or regular oven to 350°F (175°C) and warm the sandwich for about 8–10 minutes—this brings back the crispiness without making the bread soggy. I avoid the microwave to preserve texture.

FAQs

What chicken works best for this sandwich?

I often use either fresh chicken breasts that I season and cook myself or shredded rotisserie chicken for a shortcut. Both deliver great flavor and texture.

Can I assemble these sandwiches ahead of time?

I recommend prepping the ingredients—cooking chicken, slicing avocado, and toasting bread—then assembling and grilling right before serving to keep everything warm and melty.

How do I prevent the avocado from browning?

I slice the avocado just before sandwich assembly and sometimes brush the slices lightly with lemon or lime juice to slow oxidation.

What’s the best cheese for melting?

I find Swiss, provolone, and cheddar all melt beautifully. For a touch of spice, pepper jack is my go-to.

Can I make this sandwich vegetarian?

I swap the chicken for grilled portobello mushrooms or marinated tofu slices and keep all the other ingredients the same for a tasty vegetarian version.
