Add 1/4 cup olive oil to a high sided sauté pan or a saucepan over medium heat. Add the parsley, oregano, rosemary and 2 stems of basil and cook for about 5 minutes or until the herbs become crisp.

Remove the herbs and discard and then add the onion and garlic to the oil, lowering the heat if needed so the onions cook gently and don't brown. Cook until the onions are transparent, about 5-7 minutes, then crush the tomatoes with your hand and add to the pan with juice.

Season with salt, freshly ground black pepper and red pepper flakes and simmer for 30-40 minutes or until the sauce reduces and thickens, stirring occasionally. Stir in the heavy cream and remove from the heat.

For crispier gnocchi: Meanwhile, pan fry the gnocchi in olive oil. Keep it to a single layer in a large pan over high heat, stirring / flipping frequently. Do multiple batches if necessary.

Alternatively for softer gnocchi: While the sauce simmers, bring a saucepan of water to a boil and add the gnocchi. Season generously with kosher salt and cook until the gnocchi float to the top of the boiling water. Drain but do not rinse.

Place the cooked gnocchi into the cooked sauce. Top with the mozzarella and sprinkle with Parmesan cheese then drizzle the tops of the gnocchi with the remaining olive oil.

Broil for 5-8 minutes or until the cheese melts and the tops become crispy. Garnish with additional basil leaves and serve immediately.
