Among the diner staples that have largely disappeared from menus, one sandwich is worth reconsidering. Canned sardines are rich in protein and important nutrients, and they can refresh simple dishes, including everyday lunch options. Sardine sandwiches were once common on dinner tables and in diners, especially because the ingredient was inexpensive, but they have since been overshadowed by choices such as tuna and meat. That does not mean they should be forgotten.
Sardines bring a savory, umami-rich flavor to familiar recipes, even adding a lift to sourdough avocado toast topped with poached eggs. One of the biggest advantages of sardine sandwiches is how easy and flavorful they are with only a few basic ingredients. No cooking is required to assemble a satisfying sandwich, and paired with sides like salad, soup, or chips, they make a reliable meal. Toasted buttered bread layered with mayo, chopped scallions, and sardines, then finished with a squeeze of citrus, chopped herbs such as parsley or cilantro, and a sprinkle of salt and pepper, is enough to quiet hunger.
Sardines are a versatile ingredient with plenty of nutrition and flavor
With so many sardine options available at the store, including varieties packed in oil, seasoned, deboned, or flavored, it is easy to find one that suits your taste and cooking style. Sardines can also upgrade a tuna melt, either by adding them to the sandwich or replacing part of the filling with melted cheese, mayo, and tapenade. Toast with cottage cheese and sardines makes a protein-rich breakfast, while a tartine topped with sardines and fresh garden herbs can create a bright lunch that carries you through the day.
If you want to turn on the oven, baking sardines in a white wine tomato sauce and spooning them over buttery toasted garlic bread is another simple way to make a hearty meal. With so many ways to use them, sardines are a practical ingredient to keep on hand in the pantry, even if they are only there for a quick sandwich.
