Boil spaghetti in lightly salted water until al dente, about 8 to 10 minutes or according to packaging instruction.
While pasta is boiling, heat extra virgin olive oil in a large pan. Fry sausages for 3 to 4 minutes until lightly browned. Add garlic. Stir fry 30 seconds.
Then add cherry tomatoes and thyme. Stir for another minute.
Drain spaghetti, reserving ½ cup (120ml) liquid. Add spaghetti, basil, reserved liquid, salt, and pepper to the pan. Toss to coat pasta with sauce. Turn off stove.
