Potato, Tomato and Mozzarella Gratin: A Mediterranean Feast in 1 Hour

INSTRUCTIONS
Step 1: Preheat the oven
Start by preheating your oven to 180°C. This temperature is ideal for even cooking of the gratin, allowing the potatoes to become tender while browning the surface.
Step 2: Prepare the dish
Generously butter your gratin dish. This step is crucial to prevent the ingredients from sticking and to make serving easier. Choose a dish large enough to hold all the layers of ingredients.
Step 3: Assembling the layers
Arrange a first layer of sliced ​​potatoes at the bottom of the dish. Make sure to distribute them evenly for even cooking. On this base, add some of the cherry tomatoes cut in half and minced garlic. This alternation of flavors is the key to a balanced gratin.
Step 4: Seasoning
Generously salt and pepper this first layer, then sprinkle with herbes de Provence. Seasoning each layer ensures a well-seasoned dish overall.
Step 5: Repeat Layering
Repeat layering potatoes, tomatoes, garlic, and seasoning until all the ingredients are used up. This method ensures that the flavors are evenly distributed throughout the gratin.
Step 6: Finish with Mozzarella
Finish by topping with shredded mozzarella. This final layer will melt and brown, forming a golden, flavorful crust.
Step 7: Add the Cream

Pour the crème fraîche over the entire gratin. It will infiltrate between the layers during cooking, providing creaminess and binding all the ingredients.
Step 8: Cooking
Bake your gratin for 40 to 45 minutes. Cooking time may vary slightly depending on your oven. The gratin is ready when its surface is golden brown and the potatoes are tender when pierced with the tip of a knife.
