Mediterranean Potato Casserole

Boil a large quantity of water in a substantial pot and immerse the potatoes within it. Add salt to the water for flavor enhancement. Bring the mixture to a rolling boil; subsequently, decrease the heat to a moderate level and cover the pot. Allow the potatoes to cook until they become tender, which typically takes around 20 minutes. Remove from heat and discard the water. Submerge the potatoes in an icy bath, replenishing the cold water as necessary to maintain their freshness. Once cooled, remove the skin and slice the potatoes into thin strips.

Preheat your oven to a temperature of 350 degrees Fahrenheit (or 175 degrees Celsius, if you prefer metric).

Anoint a casserole dish with a generous amount of olive oil to prevent sticking. Arrange an even layer of sliced potatoes within the dish; follow this by placing a layer of sardine fillets on top. Scatter diced tomatoes over the sardines, creating a visually appealing composition. Sprinkle minced garlic, chopped basil, and bread crumbs over the tomatoes to add depth of flavor.

Place the casserole dish in the preheated oven and allow it to heat through, which should take approximately 20 minutes.
