A truly one-pot pasta dinner in just 15 minutes with this no-drain pasta hack. Cook the noodles with the garlic, cheese, and tomatoes so they absorb all the yummy flavors.
To a large wide skillet or pot, add all ingredients except basil.
Pour enough water over spaghetti to barely cover, about 2 3/4 cups. Turn heat to medium and cook about 15 minutes until pasta is nearly al dente, stirring frequently to keep pasta from sticking together. About 1/2-inch of liquid should remain.
Turn off heat and let pasta sit for 3 more minutes to absorb a bit more liquid while you tear basil into shreds and sprinkle over pasta. Stir.
Other ingredients may be added to this basic recipe: quick cooking veggies (like zucchini, tomatoes or shreds of carrots), quick-cooking proteins (shrimp, fish, 3/4-inch chunks of chicken, beans or tofu,) and seasonings (lemon zest, herbs, spices, ricotta or cream cheese).
If adding extra ingredients, add another 1/4-1/2 cup water to pan.
