Cook the spaghetti in boiling salted water until just tender, then drain and set aside.
Heat olive oil in a skillet over medium heat until shimmering and fragrant.
Add the minced garlic to the skillet and sauté for about 30 seconds until it becomes fragrant and slightly golden, being careful not to burn.
Stir in the halved cherry tomatoes, and cook for 3–5 minutes until they soften and start to burst, releasing bright red juices.
Add the chopped basil and season with salt and pepper, stirring to combine and letting the flavors meld for a minute.
Toss the cooked spaghetti into the skillet, stirring gently to coat the noodles evenly with the tomato sauce.
Cook for another one to two minutes, allowing the pasta to absorb some of the sauce and flavors to deepen.
Remove from heat, check the seasoning, and adjust with more salt or pepper if needed.
Serve the cherry tomato pasta hot, garnished with additional basil if desired for a fresh touch.
