Today I am sharing a delicious and simple recipe for creamy penne with zucchini and walnuts, a vegetarian recipe that will make your mouth water. This dish is great if you want to cook quickly and easily and enjoy good food.
This recipe uses fresh ingredients. The zucchini gives a soft bite and a healthy portion of vegetables, the walnuts have a nutty taste, and the Parmesan flavor makes it salty. That added to a creamy sour cream sauce, a delicious recipe.

A creamy and savory dish: Penne with Zucchini
I like pasta, always have. And on a weekday, a quick pasta meal is a godsend. Sports, appointments, and meetings. Everyone comes home at a different time. But in addition to good food, it also contains enough vegetables. And that's why this penne with zucchini dish.
Zucchini and walnuts may not be a combination that immediately comes to mind, but in the delicious pasta recipe, it is super tasty. You stew the zucchini together with onion and some thyme so that it absorbs all those delightful flavors. And in the meantime, you cook the penne. You stir it with sour cream and some parsley (deliciously fresh) and serve it with Parmesan cheese
and chopped walnuts.
Of course, you can also mix the last two in advance, but when you serve them separately, the walnuts will remain crunchy, and the Parmesan cheese will give it a great flavor.
I hope you enjoy this dish as much as we do!
