Fennel is all too often looked over in the produce section of the grocery store. In fact, when I purchased the fennel for this recipe, it wasn’t even listed under “fennel” in their system. The code on it was for celery root.

With it’s huge bulb and furry-looking stalks, it can be a bit intimidating if you’ve never made it before. But, this Roasted Fennel recipe is actually really easy to prepare and good for you too.

Fennel gets a bad rap, especially from those who don’t like anise or black licorice flavor. It does have a very similar taste, so if you are really not a fan of those foods, you might not love fennel.

Personally, I don’t love anise or black licorice, although the flavor does remind me of my grandmother’s pizzelle recipe that she used to make during the holidays.

It took trying fennel a few times for it to really grow on me. It’s low in carbs so it’s another vegetable option when following a low carb or keto diet, like I do most of the time. The more options, the better, right?

All this is to say, give it a chance! You might end up loving it.
