Recipe off-roading: I halved most of the ingredients, swapped in spaghetti for the pasta, and added butter and cream. It turned out great! No need to add more salt, and it came together quickly and perfectly. —Natalie Wittmann
Cherry tomatoes, halved
Onion, thinly sliced
Cloves of garlic, thinly sliced
Red pepper flakes
Basil, plus two julienned leaves for garnish
Combine pasta, tomatoes, onion, garlic, red pepper flakes, basil, oil, and butter in a large skillet over high heat. Break the pasta if necessary. Heat everything until butter melts, stirring, about 1 minute.
Add water, salt, and black pepper, and bring to a boil over high heat. Boil, stirring frequently, until pasta is al denté and water has nearly evaporated, about 9 minutes.
Add heavy cream, and stir to thoroughly combine. Divide in two bowls, and garnish with basil and parmesan.
