For Serving (Optional)

tomatosliced; season lightly with salt and pepper
Instructions
Place chicken breasts in a medium saucepan, cover with cold water or broth by at least 1 inch, and add a pinch of salt. Bring to a gentle boil over medium-high heat, then reduce to a simmer and cook for 15–20 minutes until an instant-read thermometer reads 165°F (74°C).
Remove chicken from the water and let it rest on a cutting board for 5–10 minutes, then shred with two forks into bite-sized pieces (or use a hand mixer on low for quick shredding). Pat dry if needed to remove excess moisture.
Finely dice the celery stalks into ¼-inch pieces and mince the red onion very finely. Set both aside in a small bowl.
In a large mixing bowl, whisk together the mayonnaise, fresh lemon juice, Dijon mustard, garlic powder, salt, and black pepper until smooth. Taste and adjust seasoning as needed.
Add the shredded chicken, diced celery, and minced red onion to the dressing and gently fold everything together until evenly coated. Do not over-mix — the chicken should remain textured.
Cover the chicken salad and refrigerate for at least 30 minutes to allow the flavors to meld. This step is optional but highly recommended for the best flavor.
Toast the bread slices lightly if desired, then spread with a thin layer of butter or mayonnaise on each slice for added richness.
Layer lettuce leaves on 4 bottom bread slices, then spoon about ½ cup of chicken salad onto each, top with sliced tomato if using, close with the top bread slice, and cut diagonally. Serve immediately.
Notes
Rotisserie chicken is a great shortcut — it's already juicy and seasoned. Just be aware it's saltier than poached chicken, so taste before adding extra salt.
Chill the chicken salad for at least 30 minutes before serving — the flavors come together much more cohesively after resting in the fridge.
Always add mayonnaise gradually and stop when you reach your preferred creaminess. Some prefer a drier salad; others like it extra creamy.
Pat the cooked chicken dry with paper towels before shredding to prevent a watery chicken salad.
For a lighter version, substitute half or all of the mayonnaise with plain Greek yogurt — it keeps the creaminess while reducing fat and calories.
To shred chicken quickly, place warm cooked chicken breasts in a bowl and use a hand mixer on low speed — it shreds perfectly in under 30 seconds.
Store leftover chicken salad in an airtight container in the fridge for up to 4 days. Do not freeze — the mayo will separate upon thawing.
Always store chicken salad and bread separately when meal prepping; assemble sandwiches fresh each day for best texture.
For a Cranberry Pecan variation, stir in ¼ cup dried cranberries and ¼ cup chopped toasted pecans before chilling.
Discard any chicken salad left at room temperature for more than 2 hours to ensure food safety.
