Fennel Gratin

I never used to know what to do with fennel, but these days, I can’t get enough of it. Fennel is the most wonderfully versatile vegetable. You can slice raw fennel thin and serve it with a little shaved Parmesan for a crisp salad. Or you can plop it in the oven with a little balsamic and roast it until it gets sweetly caramelized. Fennel has a special affinity for Parmesan, and in this simple gratin fennel wedges are tossed with breadcrumbs, Mozzarella and Parm, and baked until golden brown. A lovely side for lighter fare, such chicken or fish, and would also work well as a dressy side for a holiday meal.

  • Salt
  • 3-4 Tbsp olive oil
  • 1/2 cup grated parmesan cheese (about 2 ounces)

Method

1 Cut off the fronds and stems of the fennel and save them for another dish; they are a great addition to stocks and broths. Cut the bulbs in quarters, then 1-2 inch pieces; discard the woody cores.

2 Grease a casserole pan or gratin pan with 1 tablespoon olive oil and preheat the oven to 375°.

3 Boil the fennel in a medium pot of salty water for 5-6 minutes, or until the fennel is just about tender. Drain well and toss with a tablespoon of olive oil.

4 Mix the parmesan, thyme and bread crumbs, then mix half of that mixture with the fennel. Add the fennel to the casserole in an even layer. Top with the mozzarella cheese, then the rest of the parmesan-bread crumb mixture. Drizzle 1-2 tablespoons of olive oil over the top.

5 Cover the casserole and bake for 20 minutes. Take the cover off and bake until the cheese is well browned, about 15 more minutes. Let the gratin rest for 5 minutes before serving. Garnish with chopped fresh fennel fronds.

    I’d like to use this recipe to bring to a Christmas dinner in a friend’s home. Should I bake it there or at home and reheat it there?

    Love fennel!

    I think you could go either way, though if you bake it there the top will be crispier. ~Elise

    As I recall, fennel has a “licor-ishy” flavor – when this is cooked as recommended, does that flavor diminish somewhat?? i’d like to try this recipe – sounds really good but only if the above is true. Thanks very much.

    The licorice flavor is much reduced once the fennel is cooked. -Elise

    Special place in my heart for fennel. Another great option is to add it French bread with a little oil, bit of cheese, splash of lemon, and broil for a few minutes. One of my favorites.

    Oh my God, this Fennel gratin is so delicious!!! I’ve just cooked it and it came first, so I have to stop myself from eating it before rice and fish will be finished! I haven’t ever tried fennel before and first thought that its smell is too strong and unusuall for me, but the majority of it disappeated after it been cooked! Elise, thank you for this amaizing recipe!
