Peel and boil 1 kg of potatoes until tender. You can also bake them for even better flavor.
Mash the potatoes until smooth and let them cool slightly.
Add eggs and flour to the mashed potatoes. Knead into a dough that is soft and slightly sticky.
Lightly flour your work surface, roll the dough into a thick sheet, and cut it into strips. Divide the strips into small pieces.
Shape the dough into oval dumplings. Use a fork or toothpick to create patterns on the surface of the gnocchi.
To make the sauce, heat butter and olive oil in a pan.
Add the sliced garlic and cherry tomatoes, cooking until soft and fragrant.
Pour in cream and Greek yogurt. Stir in the gnocchi, mozzarella, and Parmesan. Garnish with parsley and basil.
