Gnocchi with Tomato Sauce and Mozzarella Recipe

Directions

Heat olive oil in a saucepan over medium heat; cook onion until soft and translucent, about 5 minutes. Add passata and salt; simmer over low heat while you prepare the gnocchi.
Bring a large pot of lightly salted water to a boil. Cook gnocchi in the boiling water until they float to the top, 2 to 4 minutes. Drain.
Set an oven rack about 6 inches from the heat source and preheat the oven's broiler.
Pour 1 ladle of tomato sauce into the bottom of a baking dish. Add gnocchi, remaining tomato sauce, and Parmesan cheese; toss to combine. Arrange cubes of mozzarella cheese evenly on top.
Place baking dish in the oven and broil until mozzarella cheese is melted and sauce has slightly reduced, 5 to 10 minutes. Remove from oven and garnish with basil leaves before serving.
