Bring a large pot of salted water to a boil. Add spaghetti and cook according to package instructions until al dente.

Drain the pasta in a colander and set aside, reserving a cup of pasta water.

In a large skillet, heat olive oil over medium heat. Add minced garlic and sauté for 1-2 minutes until fragrant.

Add halved cherry tomatoes and cook for about 5-7 minutes until they start to soften.

Stir in chopped basil, salt, and pepper. Cook for another 2 minutes.

Add the cooked pasta to the skillet, tossing to combine. If the mixture is too dry, add reserved pasta water a little at a time.

Serve hot, topped with grated parmesan cheese if desired.
