Make Ahead Options
These gourmet chicken sandwiches are a fantastic meal prep solution for busy home cooks! You can prepare the creamy filling up to 24 hours in advance by shredding the cooked chicken and mixing it with the mayonnaise, sour cream, and other ingredients.

Gourmet Deli-Style Chicken Sandwiches Recipe FAQs
What is the best way to select ripe ingredients for this chicken sandwich?
Absolutely! When selecting ingredients, ensure your chicken is cooked to perfection—using rotisserie chicken can save time! For veggies, choose crisp celery and fresh green onions, avoiding any that are wilted or browning. When it comes to herbs, opt for vibrant dill, as wilted herbs can offer a muted flavor.
How should I store leftover chicken sandwiches, and how long do they last?
Very good question! Store your assembled chicken sandwiches in an airtight container or wrap them tightly with plastic wrap. They will stay fresh for up to 2 days in the refrigerator. For best flavor and texture, consume them within this time frame to enjoy the delightful creaminess!
Can I freeze the filling for later use?
Absolutely, you can freeze the filling! To do this, spoon the chicken filling into an airtight container or freezer-safe bag. It will keep well in the freezer for up to 3 months. When you’re ready to enjoy it, simply thaw it in the refrigerator overnight and give it a quick stir before using.
What should I do if my chicken sandwiches are too dry?
If you find your sandwiches have turned out dry, there are a couple of things you can do! First, check that the chicken is shredded finely to help it absorb the creamy filling. If you’ve already made them and they’re dry, consider adding a little more mayonnaise or sour cream to each sandwich when serving, or incorporate a flavorful dipping sauce on the side.
Are there any dietary considerations I should keep in mind?
Very much so! If you or your guests have nut allergies, you can simply omit the walnuts from the filling. Alternatively, for a crunchy texture, consider replacing them with sunflower or pumpkin seeds. Additionally, ensure to use allergen-free mayonnaise if needed, or substitute with a mixture of full-fat yogurt or a vegan alternative.
