1Bring a large pot of salted water to a boil. Add the penne pasta and cook according to package instructions until al dente. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant.
Add the diced zucchinis to the skillet and cook for about 5-7 minutes, stirring occasionally, until they are tender and slightly golden.
Reduce the heat to low and stir in the light cream. Let it simmer for 2-3 minutes until slightly thickened.
Add the cooked pasta to the skillet and toss to coat it evenly with the creamy zucchini mixture.
Stir in the arugula and let it wilt slightly, about 1-2 minutes.
Season with salt, pepper, and crushed red pepper to taste.
Serve the creamy zucchini and arugula pasta warm, garnished with additional arugula or grated cheese if desired.
