Roasted fennel is one of my favorite side dishes for fall and winter; it goes well with just about any roast—especially chicken and lamb, or with a simple soup like Stracciatella. If you lean pescatarian, don't worry! This roasted fennel recipe pairs beautifully with fish—especially as an accompaniment to broiled salmon.

If you’ve never roasted fennel before, you’re in for a savory treat. Slicing fat fennel bulbs into wedges then roasting them at a moderately high temperature brings out the best in this oddly beautiful vegetable. The heat caramelizes its edges, turning it from crunchy to meltingly tender in less than 30 minutes. Plus, the licorice flavor dominant in raw fennel is tamed in the oven, turning this often underused vegetable sweet and mellow.

For this easy roasted fennel recipe, I like to dress it in a little extra virgin olive oil, fresh herbs, lemon and a sprinkle of good Parmesan cheese. That’s it! Simple really is best when it comes to creating side dishes for weeknight meals.

Serve roasted fennel as is or give it an elegant touch by garnishing it with a few drops of good balsamic vinegar to bring out its sweet notes.

Ingredients for Roasted Fennel with Parmigiano Cheese

Lemon zest and a couple of other key ingredients are all you need to make this rustic yet elegant side dish:

  • Fennel bulbs: Fennel can have either slim or fat bulbs; look for the fat ones, which are better for roasting. The bulbs are topped with long stalks with feathery fronds. You may be tempted to use the stocks, but they are tough, so slice those off right where they meet the bulb. I like to save the stalks to flavor soup stock or to enhance the flavor of commercial broth. Mince the fronds and use as you would dill or other fresh herbs. To cut the fennel bulbs, slice them into quarters lengthwise, pulling off any tough out layers. Then slice each quarter in half lengthwise, and each bulb will give you 8 wedges, for a total of 24.
  • Extra-virgin olive oil: Use the best you can; I like Italian olive oil made by small producers. The oil tastes fresher and brings out the best in roasted vegetables.
  • Herbs: Finely chopped fresh herbs brighten the flavor of roasted fennel. Use your favorites. For this recipe I like a mix of oregano, thyme and the fennel fronds.
  • Lemon zest: This is my secret ingredient when roasting vegetables. Adding zest, even just a little, wakes up all the flavors.
  • Spices: A grinding of black pepper is all you need, but when I want to magnify the fennel flavor, I add a pinch of freshly ground toasted fennel seed. Its warm perfume gives roasted fennel a touch of luxury. To make it, toast 2 tablespoons fennel seeds in a small skillet just until they turn a shade darker, and you can smell their fragrance. Let the seeds cool, then grind in a spice grinder. You’ll only need a pinch for this recipe, so store the rest in a small container with a tight-fitting lid, like a spice jar. Sprinkle ground fennel in soups and stews like Cioppino, on baked fish, or even roast potatoes.
  • Parmigiano cheese: There are no good substitutes for rich, savory, imported Parmigiano-Reggiano, so be sure to seek out the good stuff and only grate as much as you plan to use—about ⅓ cup here.
  • Balsamic vinegar: This is an optional add, but every now and then I garnish roasted fennel with just a few drops of really good, syrupy aceto balsamico from Modena or Reggio Emilia, the two places in Italy that produce genuine, top-quality products.

How to make Roasted Fennel with Parmigiano Cheese

A hot oven is key to properly roasted fennel wedges, with caramelized edges and a sweet, tender core. Position an oven rack in the upper third of the oven and preheat it to 400°F.

  • Cut the fennel: Trim the end of the fennel bulb and cut the stems off, then slice each bulb in half from the stem side to the root, then cut into quarters. You should end up with 24 wedges. Put the wedges into a large, shallow bowl. Add 4 tablespoons extra-virgin olive oil, 2 tablespoons finely chopped fresh herbs (a mix of oregano, thyme, parsley, and fennel fronds), the zest of one lemon, a generous pinch of fine salt, and about ¼ teaspoon freshly ground pepper. If you plan to add ground fennel seed, now is the time to do it.a sliced bulb of fennel.
  • Toss it all together: Using a large spoon or spatula, gently toss everything together. You'll want to make sure to coat all the fennel bulbs evenly.pieces of seasoned uncooked fennel in bowl next to a measuring spoon and a lemon on a cutting board.
  • Spread into a single layer: Spread the fennel bulbs out onto a rimmed baking sheet lined with parchment paper. The parchment will allow the fennel to roast and brown properly without sticking to the baking sheet.pieces of seasoned uncooked fennel on a baking sheet lined with parchment paper.
  • Roast: Roast the fennel for 15 minutes, the fennel should turn golden. Sprinkle ⅓ cup freshly grated Parmigiano cheese over the roasting fennel, coating each wedge evenly. If you want to be generous, use ½ cup. Roast the fennel for an additional 10 to 15 minutes, or until the cheese is nicely browned, and the edges of the fennel bulbs are caramelized.roasted fennel with parmigiano cheese on a baking sheet lined with parchment paper.

What to Serve with Roasted Fennel

I like roasted fennel with just about anything. It would complement this Balsamic Chicken recipe nicely, or serve it with hearty vegetarian main dish like Vegetarian Baked Ziti.

Roasted fennel isn't just for sides. You can use it to top your favorite flatbreads too. It makes an excellent topping for pizza! Make this Easy Grilled Pizza and try it for yourself.

Roasting this crunchy licorice-scented bulb tames it and brings out its sweet, mellow side. The caramelized wedges go perfectly with roast chicken, lamb, or even salmon fillet.

  1. This looks like it makes a lot. Could you freeze the leftovers and use later for pizza? I can't wait to try this!

    1. Hi, Karen. It's not something we've tried before, so I'm not sure how well the roasted fennel would survive the thaw. If you give it a go, though, we'd love to hear your thoughts!

  2. Fennel is my favorite vegetable - cooked. I dont care for raw fennel. Add cheese to roasted fennel and it is over the top!
