Fiddlehead Fern with Morel Mushrooms Recipe
2026-05-18
IMPORTANT: This recipe uses ostrich fern (Matteuccia struthiopteris) fiddleheads, NOT bracken fern (Pteridium aquilinum). Bracken fern contains ptaquiloside, a carcinogenic compound, and should never be consumed. Ostrich fern is safe when properly cooked.
Ingredients
For 4 servings:
- 300g ostrich fern fiddleheads — young, tightly coiled
- 200g fresh morel mushrooms — cleaned
- 3 cloves garlic — minced
- 50ml extra virgin olive oil
- 30g butter
- 1 lemon — juice
- Fresh thyme — 2-3 sprigs
- Sea salt and pepper to taste
Preparation
Step 1 — Prepare the Fiddleheads (10 min)
- Wash fiddleheads thoroughly in cold water
- Remove any brown papery husks
- Blanch in boiling water for 5 minutes (essential — removes bitterness and any residual toxins)
- Drain and pat dry
Step 2 — Prepare the Morels (10 min)
- Clean morels by halving lengthwise and rinsing briefly
- Pat dry carefully (they absorb water)
- Cut large ones in half
Step 3 — Cook (10 min)
- Heat EVOO and butter in a large pan
- Add garlic, sauté 1 minute
- Add morels, sauté 5 minutes until golden
- Add fiddleheads, sauté 3-4 minutes
