This satisfying sandwich combines tender cooked chicken with a zesty avocado mayo spread, fresh tomato slices, and melted provolone or Swiss cheese. The sourdough bread gets buttered and grilled to golden perfection, creating crispy edges that complement the creamy interior. Ready in just 25 minutes, these melts are perfect for lunch or dinner when you want something warm and filling without spending hours in the kitchen.
Rainy Tuesday afternoons were made for sandwiches like this. I'd come home from work starving, throw whatever was in the fridge between two slices of bread, and somehow end up with something that felt like a hug. The chicken avocado melt started as one of those desperate experiments but turned into a regular request from my roommate who would drift into the kitchen whenever she smelled butter hitting the pan.
Last winter my sister came over complaining about a terrible breakup. I made four of these sandwiches and we ate them standing up at the counter, butter dripping down our wrists, neither of us saying much. She left with a full stomach and leftovers, and texted me at midnight that it was the best thing she'd eaten in months.
Ingredients
- 2 cups cooked chicken breast: Use rotisserie chicken for the fastest route or poach your own breasts ahead of time
- 2 ripe avocados: One gets mashed into the spread, the other sliced for fresh texture inside
- 4 slices provolone or Swiss cheese: Provolone melts beautifully but Swiss adds that nutty sharpness
- 8 slices sourdough or whole grain bread: Sourdough holds up better to grilling without getting soggy
- 1 small tomato thinly sliced: Adds a bright acidity that cuts through all the creaminess
- 2 tablespoons mayonnaise: Essential for the spread but Greek yogurt works if you want to lighten it up
- 1 tablespoon Dijon mustard: Just enough subtle heat to keep things interesting
- 1 tablespoon fresh lemon juice: Keeps the avocado from browning and adds brightness
- Fresh cilantro or parsley chopped: Optional but brings a fresh pop of color and flavor
- Salt and freshly ground black pepper: Dont skip seasoning each layer
- 2 tablespoons unsalted butter softened: Butter the bread generously for that golden crunch
Instructions
- Make the creamy avocado spread:
- Mash one ripe avocado with lemon juice, mayonnaise, Dijon mustard, salt, and pepper until smooth. It should be spreadable but still have some texture.
- Spread and layer your sandwiches:
- Evenly coat 4 bread slices with the avocado mixture then pile on chicken, tomato, remaining avocado slices, and cheese. Sprinkle with fresh herbs if you have them handy.
- Assemble and butter:
- Top with remaining bread slices and butter the outside of each sandwich generously on both sides. This is what creates that irresistible golden crust.
- Grill to perfection:
- Cook in a hot skillet or griddle over medium heat for 3 to 4 minutes per side. Press gently with your spatula and watch for the cheese to start oozing out the sides.
- Serve immediately:
- Slice each sandwich diagonally and eat while the cheese is still molten and the bread is at its crispest.
These became my go-to dinner during those months when cooking felt like too much effort but I still wanted something that felt cared for. Something about the combination of warm chicken and cool avocado just works in ways that make sense the moment you take that first bite.
Make It Your Own
Bacon changes everything. Cook it until crispy and layer it between the chicken and cheese. Baby spinach adds freshness and a little crunch without overpowering anything else. Sometimes I'll add pickled red onions for a tangy kick that wakes up the whole sandwich.
Perfect Pairings
A simple tomato soup turns this into a full meal. For something lighter, try a side salad with vinaigrette. In summer, potato salad hits the spot alongside the warm sandwich.
Storage & Reheating
These sandwiches are best eaten fresh off the griddle. The avocado spread can be made ahead and stored in the refrigerator with plastic wrap pressed directly onto the surface to prevent browning. Assembled sandwiches don't reheat well so I recommend cooking only what you'll eat immediately.
- If you're meal prepping keep the components separate and assemble just before eating
- The avocado spread keeps for about 2 days in the refrigerator
- Already grilled sandwiches can be loosely wrapped and frozen then reheated in a 350°F oven for 10 to 12 minutes though the texture won't be quite the same
Some meals are just meant to be eaten with your hands, leaning over the counter, letting everything fall apart a little bit. This is one of those recipes that reminds you simple food done well is sometimes all you really need.
Recipe Questions & Answers
- → What bread works best for these melts?
-
Sourdough or whole grain bread works excellent because they hold up well to grilling and provide sturdy structure. The slight tang of sourdough complements the creamy avocado and mild cheese beautifully.
- → Can I use rotisserie chicken?
-
Absolutely! Rotisserie chicken works perfectly and actually saves prep time. Just shred the meat and layer it on. The seasonings from rotisserie chicken add extra flavor to the sandwich.
- → How do I prevent the bread from burning?
-
Keep the heat at medium and grill for 3-4 minutes per side. Don't press too hard with the spatula—just gentle pressure helps the cheese melt without tearing the bread. Watch closely as sourdough can brown quickly.
- → Can I make these ahead of time?
-
You can assemble the sandwiches and butter the bread in advance, then grill them just before serving. For best results, grill within an hour of assembly to prevent the bread from getting soggy from the avocado spread.
- → What cheese substitutes work well?
-
Sharp cheddar adds great flavor contrast, mozzarella creates amazing cheese pulls, or pepper jack brings a nice kick. Gouda also melts beautifully and adds a smoky depth to the chicken and avocado.
- → How do I know when the sandwich is done?
-
The sandwich is ready when both sides are golden brown and crispy, and you can see the cheese melting out the sides slightly. The bread should feel firm and toasted, not soft or doughy.
