Health Benefits

What the Research Says

Blood Glucose ControlModerate Evidence

Studies suggest that fennel seed extracts may help lower blood sugar levels and improve markers of metabolic health, though more human clinical trials on the vegetable bulb specifically are needed.

Anti-Inflammatory PropertiesEmerging Evidence

Preliminary research indicates that the concentrated compounds in fennel demonstrate anti-inflammatory effects which may support systemic nervous system health, though data is currently limited to animal and in-vitro models.

How to Cook It

Preparation Tips

  • •Shave the bulb paper-thin using a mandoline for a crisp, refreshing raw salad base.
  • •Do not discard the green fronds; use them as a delicate, aromatic herb garnish for soups or fish.
  • •Roast fennel wedges with olive oil and a squeeze of lemon to mellow the licorice flavor into a sweet, caramelized finish.

Flavor Pairings

  • •Citrus fruits like blood orange or grapefruit
  • •Fresh fish and white-fleshed seafood
  • •Apples and crisp pears
  • •Toasted walnuts and hazelnuts

Storage Tips

  • •Cut the stalks off the bulb if they are very long to save fridge space, but keep them attached to the bulb if you plan to use them within a day or two.
  • •Keep the bulb in a perforated plastic bag or wrapped loosely in a damp paper towel to maintain humidity.
  • •Use the feathery fronds quickly, as they wilt faster than the sturdy base.

How to Pick the Best One at the Store

Selection Tips

  • •Choose bulbs that are firm, white, and feel heavy for their size.
  • •Ensure the surface is free of cracks, bruises, or dark brown spots.
  • •Look for bright green, vibrant fronds that show no signs of wilting or yellowing.
  • •Avoid bulbs that appear split at the base, as this can indicate the plant is past its prime.
