Baked zucchini and potatoes gratin, a quick and tasty side dish, perfect to accompany meat and fish main courses. This recipe of baked potatoes and zucchini with a hint of thyme is a great accompaniment and can be prepared in advance to be baked just before sitting at the table.
The recipe is made with thinly sliced zucchini and potatoes, topped with fresh thyme and a delicious breadcrumb coating with grated cheese, garlic powder, and chopped parsley. I occasionally used frozen parsley because I had it stocked in the freezer, but you could also use fresh parsley.
Lately, I use garlic powder because I find the taste is less strong compared to fresh garlic, and with a daughter at home who doesn’t like it at all, I prefer this solution. However, if you’re luckier than me, you can use fresh garlic, chopping it, of course, before adding it to the breadcrumb mix. You can also replace thyme with other herbs of your choice.
Nowadays, potatoes and zucchini are among the most loved vegetables and can also be used to prepare many other recipes. If you haven’t tried them yet, I recommend trying the oven-baked veal skewers: a quick and tasty main dish that always pleases everyone at home.
