In a medium sized saucepan, heat 1 tablespoon olive oil over medium-high heat. Add garlic and sauté for 1 minute. Add onion and carrots to saucepan. Let cook, stirring occasionally, for 5 minutes until onions are translucent and the carrots begin to soften.
Add meat to saucepan and let cook until no pink remains.
Add tomato sauce, diced tomatoes, spices, and 1 tablespoon fresh basil to the pan and mix well.
Bring to a boil over high heat. Reduce heat to low and let simmer for 15 minutes. Taste and adjust seasoning and remove from heat.
In a large skillet, heat remaining tablespoon of olive oil over medium-high heat. Add in zucchini noodles and big pinch of salt and pepper and let cook for 2-3 minutes. The zucchini noodles will continue to cook once you take them off the heat.
Transfer zucchini noodles to a plate, and top with meat sauce, fresh basil, and parmesan if using and serve immediately.
