What is a gratin?
A gratin is a French word for a casserole dish with a golden-brown crust. It usually contains eggs, cream, or cheese. This cooking method works well with potatoes, cauliflower, and broccoli. This fennel and potato gratin is one of my go-to recipes in the spring. I like to serve it with Mediterranean grilled salmon.

A great spring dish
If you grow your food, like me, you would know fennel is a spring vegetable that does not last long in the garden. So whenever it is in season, I try to prepare it in the most memorable ways to enjoy with the family. We used to eat raw or steamed as a child, which was not bad.
This recipe is easy and simple for a weeknight family dinner, yet rich and elegant for a special celebration. The flavors balance each other in harmony with a subtle highlight of the licorice taste of the fennel.

Meet fennel
Fennel is a Mediterranean plant that has made it to every corner of the world. It has a pale bulb and a tall, dark green stalk with feathery foliage. All plant parts are edible and used differently in each cuisine. Chop the leaves and use them as an aromatic herb in your bread dough and pickling brines. You can also use the seeds as a spice or enjoy them as a snack. The tender bulb and young stalks make delicious stews, tajines, and gratins.
Nutritional value of fennel
This spring vegetable is low in calories and rich in vitamins. All parts of the fennel plant and seeds are packed with nutritional minerals such as manganese, potassium, and calcium. The bulb and stalks are a great source of fiber that enhances gut health. It is also high in oils, hence the licorice flavor which is good for bad breath. Fennel seed tea is well known to improve lactation in breastfeeding women.
