This Turkey Sandwich on Sourdough is stacked with deli turkey, crisp lettuce, juicy tomato, and cheddar, all layered on tangy sourdough with mayo and mustard. It's quick, customizable, and perfect for an easy lunch.

I'm not usually a big sandwich lover, but when I do crave one, it's usually on a sunny beach day in the summer. And it’s always a turkey and cheese sandwich.
And of course, now that I’ve been baking my own sourdough bread for three years, it has to be made on tangy sourdough.
You can use any type of sourdough bread you like - whether it’s my classic crusty loaf, a soft sandwich bread, multigrain, honey wheat, or even dill pickle sourdough (yum!).
This sourdough turkey sandwich recipe is exactly how I love mine - mayo, honey mustard, sharp cheddar cheese, shredded iceberg lettuce, and juicy, ripe tomatoes, all piled high with turkey breast.
Sometimes, I’ll add sliced red onion and avocado if I'm feeling a little fancy.
No matter how you make it, I hope you’ll give it a try and love it as much as I do. Maybe even take it on your next trip to the beach!

Ingredients & Substitutions
Here are some notes on the key ingredients. For the full list of ingredients, check out the recipe card below.
- Sourdough Bread- I used my classic crusty sourdough loaf, but store-bought works too. For a softer bite, try sourdough sandwich bread or honey wheat sourdough.
- Turkey Breast- Use your favorite sliced deli turkey or leftover roasted turkey.
- Cheddar Cheese- Adds a sharp, savory flavor. Swap with Swiss, provolone, pepper jack, or your favorite cheese.
- Mayonnaise- For classic deli flavor and creaminess. Swap for a flavored mayo like spicy garlic or chipotle for a twist.
- Mustard- Honey mustard for sweetness, or Dijon for a bit of kick.
- Iceberg Lettuce- For that classic crunch and freshness.
- Tomato- Use ripe beefsteak or heirloom tomatoes for the best flavor.
- Optional Add-Ins- Customize with sliced avocado, red onion, bacon, pickles, spinach, or arugula.
