Heat the olive oil in a large skillet over medium heat. Add the ground beef, seasoning with 1 teaspoon of salt and 1/2 teaspoon of black pepper. Cook until browned, about 5-7 minutes, breaking the meat apart as it cooks.
Pour the tomato sauce into the skillet with the browned beef. Reduce the heat to low and let it simmer for 10 minutes so the flavors blend.
Add the drained zucchini noodles to the skillet. Toss gently for 2 to 3 minutes just until warmed through, being careful not to overcook them to prevent sogginess.
Remove from heat and garnish with grated parmesan cheese and chopped fresh basil before serving.
