Ingredients
  

Sandwich Base
  • 8 slices sourdough or whole-grain bread slices
  • 2 tablespoons unsalted butter
  • 4 slices slices sharp cheddar or Monterey Jack
Chicken-Avocado Filling
  • 2 cups cooked shredded chicken (rotisserie or roasted)
  • 1 medium ripe avocado
  • 3 tablespoons mayonnaise
  • 1 teaspoon Dijon mustard
  • 1 tablespoon fresh lemon juice
  • 2 tablespoons red onion, finely minced
  • 2 tablespoons celery, finely chopped
  • 1 tablespoon fresh cilantro or parsley, chopped
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon freshly ground black pepper
To Serve (optional)
  • 1 medium ripe tomato slices
  • 4 leaves crisp lettuce leaves
  • 4 slices pickles

Equipment

  • Large mixing bowl
  • fork or potato masher
  • Knife
  • Cutting board
  • large skillet or griddle
  • Spatula

Method
 

Prepare the Chicken-Avocado Filling
  1. In a medium bowl, mash the avocado with lemon juice until mostly smooth with a few small chunks remaining.
  2. Add the shredded cooked chicken, mayonnaise, Dijon mustard, red onion, celery, and chopped cilantro or parsley to the bowl.
  3. Season with kosher salt and freshly ground black pepper. Stir until well combined and taste; adjust seasoning or lemon as needed.
Assemble the Sandwiches
  1. Spread a thin layer of butter on one side of each bread slice. Place four slices, butter-side-down, on a clean work surface for assembly.
  2. Divide the chicken-avocado mixture evenly among the four bread slices, spreading it across the center of each slice.
  3. Top each portion of filling with a slice of cheese, and add tomato slices and lettuce if using. Cover with the remaining bread slices, butter-side-up.
Cook and Finish
  1. Heat a large skillet or griddle over medium heat. Place two assembled sandwiches in the skillet, pressing down gently with a spatula or a second pan to encourage even contact.
  2. Cook for 3–4 minutes per side, or until bread is golden and cheese is melted. If needed, lower heat slightly to allow cheese to melt without burning bread; cover the skillet briefly to hasten melting.
  3. Transfer sandwiches to a cutting board and let rest 1 minute. Slice in half and serve warm with pickles or a side salad.

Notes

Overview

This creamy chicken avocado melt is a quick, crowd-pleasing sandwich that transforms leftover chicken into a comforting meal. Bright lemon and crunchy celery keep the filling lively while melted cheese adds the indulgent finish. 🍽️

Storage & Reheating

Store leftover filling in an airtight container in the refrigerator for up to 2 days. Keep assembled, uncooked sandwiches wrapped and refrigerated for up to 24 hours. Reheat cooked sandwiches in a skillet over low heat, covered, for 3–5 minutes per side, or in a 350°F (175°C) oven for 8–10 minutes until warmed through.

Variations

Swap cheddar for Pepper Jack for a spicier melt, or use Swiss for a milder flavor. For a lighter version, substitute Greek yogurt for half the mayonnaise. Add sliced apple or thinly sliced radish for extra crunch.

FAQs

When is this sandwich best served?
This sandwich is ideal for lunch, a quick weeknight dinner, or casual weekend brunch. It’s also good for packed lunches if eaten within a few hours.
Can I substitute the chicken?
Yes—use shredded turkey, cooked white beans for a vegetarian twist, or canned chicken in a pinch. Adjust seasonings and texture as needed.
Is this recipe suitable for common dietary preferences?
The recipe can be adapted for dairy-free diets by using dairy-free cheese and a plant-based spread, and for lower-fat preferences by reducing mayo or using yogurt.
How long is the filling safe to store?
Store filling in the refrigerator and use within 48 hours for best quality and safety.
How many sandwiches does the recipe make and what is a portion?
This recipe yields four sandwiches. One sandwich counts as one serving; halve for smaller portions.
Any tips for preparing the filling quickly?
Use pre-shredded rotisserie chicken and a fork to quickly mash the avocado. Mix mayo and mustard ahead of time to streamline assembly.
Can I make the filling ahead of time?
Yes—mix the chicken elements up to 24 hours ahead and refrigerate. Add mashed avocado and lemon shortly before assembling to preserve color and freshness.
Can these sandwiches be frozen?
Assembled cooked sandwiches don’t freeze well because the avocado texture changes. You can freeze the chicken portion (without avocado) for up to 2 months; thaw and stir in fresh avocado when ready to serve.
What common mistakes should I avoid?
Avoid over-mashing the avocado so the filling keeps texture, and don’t toast the bread on too high heat or the outside will burn before the cheese melts.
When should I adjust seasonings?
If using pre-seasoned store-bought chicken or canned chicken, reduce added salt. Taste and adjust lemon, salt, and pepper before assembling.
