Make the garlic confit: Preheat oven to 250. Peel garlic and add to a ramekin along with lemon rind and enough oil to cover the garlic. Bake for about 2 1/2 hours.
Make the sauce: When it’s done, remove from oil and add to a food processor with butter, lemon juice, lemon zest, sea salt and pepper. Blend until smooth and creamy.
Cook the pasta: Meanwhile, heat a salted pot of water and bring to a boil. Cook the gnocchi for only 2 min or so (less than the full amount since it will go back on the stovetop). Reserve pasta water. Transfer pasta to a large skillet and add 3-4 tbsp dollops of the confit butter.
Finish pasta sauce: Add in cream, followed by pasta water in increments. Cook on low heat until everything starts to get creamy. Add in parmesan cheese and more pasta water as needed. Top with fresh basil, another nice squeeze of lemon, salt and pepper. Enjoy!
