Lillet & Saffron Steamed Mussels with Spring Peas

Lillet & Saffron Steamed Mussels with Spring Peas

Lillet Blanc isn't just for golden-hour apéritifs—it makes the most intoxicating, floral broth for mussels. We're building a vibrant base with saffron and sweet fennel, steaming the shellfish until just plump, and finishing with a quick shower of bright California spring peas. It’s a breezy French bistro dinner that tastes exactly like a sunny evening on the coast.

Ingredients

  • 2 lbs fresh mussels(scrubbed and debearded. Discard any that are cracked or remain open when tapped.)
  • 1 tbsp olive oil(extra virgin)
  • 2 large shallots(finely diced)
  • 1 small fennel bulb(finely diced, fronds reserved for garnish)
  • 3 cloves garlic(thinly sliced)
  • 1/2 tsp coriander seeds(lightly crushed)
  • 1 pinch saffron threads(a generous pinch)
  • 3/4 cup Lillet Blanc(chilled)
  • 1/2 cup clam juice(or a very light fish stock)
  • 1/2 cup snap peas(thinly sliced on the bias)
  • 1/2 cup English peas(freshly shelled (thawed frozen works in a pinch))
  • 3 tbsp cultured unsalted butter(cold, cut into cubes)
  • 1/4 cup fresh tarragon and chervil(roughly chopped (substitute parsley if you can't find chervil))
  • 1 whole lemon(cut into wedges for serving)
  • 1 loaf crusty sourdough bread(thickly sliced, for soaking up the broth)

Instructions

  1. 1

    Heat 1 tbsp olive oil in a large heavy-bottomed pot or Dutch oven over medium heat. Add 2 large shallots and 1 small fennel bulb. Sweat the vegetables, stirring occasionally, until soft and translucent but not browned, about 5 minutes. We want to coax out their sweetness gently.

    5 min

    Tip: Don't rush this! Sweating aromatics slowly is the secret to a broth with real depth.

  2. 2

    Stir in 3 cloves garlic, 1/2 tsp coriander seeds, and 1 pinch saffron threads. Cook until the garlic softens and the spices become deeply fragrant, about 1 to 2 minutes. The saffron will start to tint the oil a beautiful golden hue.

    2 min

    Tip: Crushing the coriander seeds right before using releases their citrusy oils.

  3. 3

    Pour in 3/4 cup Lillet Blanc—take a sip first if you're so inclined—to deglaze the pot, scraping up any delicious bits from the bottom. Let it simmer until the liquid reduces by half, about 2 minutes. Add 1/2 cup clam juice and bring the mixture to a rapid simmer for 2 more minutes. This is our foundation.

    4 min

    Tip: Lillet Blanc has a mild bitterness and floral note that balances the rich butter later.

  4. 4

    Tumble 2 lbs fresh mussels into the bubbling golden broth. Cover the pot tightly with a lid and let them steam. Shake the pot once or twice during cooking. They are ready the exact second they pop open, which should take about 3 to 4 minutes. Discard any stubborn mussels that refuse to open.

    4 min

    Tip: I am fiercely opinionated about this: do not overcook your mussels! Pull them off the heat the moment they open so they stay plump and tender.

  5. 5

    Remove the pot from the heat immediately. Gently fold in 1/2 cup snap peas, 1/2 cup English peas, and 3 tbsp cultured unsalted butter. Swirl the pot. The residual heat will warm the peas while maintaining their bright California crunch, and the butter will emulsify into the broth, creating a quick, glossy beurre blanc.

    2 min

    Tip: Using cold butter is key here—it melts slowly, thickening the broth rather than separating.

  6. 6

    Toss in 1/4 cup fresh tarragon and chervil along with a handful of reserved fennel fronds. Transfer the mussels and all that glorious, fragrant broth to a large serving bowl. Serve immediately with wedges from 1 lemon and thick slices of 1 loaf crusty sourdough bread for mandatory dipping.

    1 min

    Tip: A little squeeze of lemon right at the end makes the saffron and Lillet flavors sing.

Chef's Notes

Lillet Blanc is a fortified wine from Bordeaux that I keep stocked for both cocktails and cooking. It adds a botanical sweetness that loves the anise notes of fennel and tarragon. If you can't find it, a dry white vermouth with a tiny splash of fresh orange juice works beautifully in a pinch. Serve this alongside a chilled, slightly funky natural Chenin Blanc.
