Caramelized fennel is a three-ingredient revelation: thinly sliced fennel bulbs cooked in butter until soft, sweet, and golden, finished with a splash of balsamic vinegar. As fennel caramelizes, its strong licorice note melts into gentle sweetness. It's the perfect accompaniment to grilled fish or chicken, and it takes barely fifteen minutes.
SERVES 4
When fennel cooks, the strong licorice or anise flavor tends to subside and, as it caramelizes, the fennel takes on a sweeter flavor. This is the perfect accompaniment to grilled fish or chicken.
INGREDIENTS
2 tbsp/30 g butter
2 medium fennel bulbs, halved and thinly sliced
½ tsp sea salt
1 tbsp/15 ml balsamic vinegar
COOKING INSTRUCTIONS
Heat butter in a large skillet over medium heat. Add fennel and cook, stirring occasionally, until soft and beginning to brown, about 10 to 12 minutes. Sprinkle with salt, stir in vinegar and remove from heat.
CHEF’S TIP
Save the feathery fronds (tops of the fennel) and chop them up to add flavor to soups and salads.
Pro Tips
- Slice the fennel thin and even so it softens and browns uniformly in the 10 to 12 minutes of cooking time.
- Stir only occasionally — leaving the fennel undisturbed for stretches is what builds genuine caramelization rather than pale sautéed vegetables.
- Salt at the end, right before the vinegar; salting early draws out moisture and prevents browning.
- The balsamic goes in off the heat to glaze rather than burn — one tablespoon is all it takes to make the sweetness sing.
- Save the feathery fronds and chop them into soups and salads — they're a free garnish with a lovely mild anise flavor.
Frequently Asked Questions
Will my kids eat fennel if they don't like licorice?
Quite possibly — cooking destroys most of fennel's anise sharpness. Caramelized fennel tastes sweet and mild, closer to a roasted onion than to licorice candy.
Can I grill the fennel instead?
Yes — thick wedges brushed with butter grill beautifully over medium heat. Finish with the same balsamic splash for that sweet-tart glaze.
What can I do with the fennel fronds?
Chop them into soups, salads, and fish dishes as a fresh herb garnish. They have a gentler anise flavor than the bulb and freeze well for later use.
What should I serve with caramelized fennel?
Grilled fish or chicken are the natural matches — the sweet, buttery fennel flatters simple proteins without competing with them.
