Mussels With Chorizo Recipe

Clean mussels

Rinse mussels under cold water. Discard any that are open and do not close when tapped. Use a small knife to remove beards. Keep mussels chilled until ready to cook.

Prepare vegetables and chorizo

Dice onion, carrot, and celery to make the mirepoix. Thinly slice the fennel bulb and reserve fronds for garnish. Remove chorizo from casing and dice into 1/4-inch pieces. Mince garlic.

Heat a large heavy-bottomed pot or Dutch oven over medium heat. Add olive oil and butter. When butter is melted and foamy, add diced chorizo and sauté 3–4 minutes until it renders fat and starts to brown. Using a slotted spoon, transfer about half of the browned chorizo to a small bowl and set aside for finishing (this keeps some texture in the finished dish). Leave remaining chorizo and its fat in the pot.

Add the diced onion, carrot, celery (mirepoix), and sliced fennel to the pot. Season lightly with half of the salt and half of the pepper. Sauté, stirring occasionally, about 6–8 minutes until vegetables soften and start to color.

Add minced garlic and crushed red pepper flakes and cook 30–45 seconds until fragrant, taking care not to burn the garlic.

Stir in the tomato paste and cook 1 minute to caramelize slightly. Add the diced tomatoes with their juices and stir to combine.

Pour in the white wine and bring to a simmer, scraping any browned bits from the bottom of the pot. Simmer until wine reduces by about half, approximately 3–4 minutes.

Add the stock, return to a gentle simmer, and taste for seasoning. Adjust with remaining salt and pepper as needed.

Add the reserved browned chorizo back into the pot and stir to distribute.

Increase heat to medium-high. Add the cleaned mussels to the pot, cover with a tight-fitting lid, and steam for 4–6 minutes, shaking the pot once or twice, until mussels open. Check after 4 minutes; continue up to 6 minutes as needed. Discard any mussels that remain closed after cooking.

Once mussels are open, stir gently to coat in the tomato–wine broth. Squeeze in the lemon juice and stir in chopped parsley and fennel fronds. Taste and adjust seasoning if necessary.

Ladle mussels and broth into shallow bowls. Scatter remaining reserved crisp chorizo pieces on top for texture. Add croutons to the bowls (or serve on the side) so they soak slightly in the broth but retain some crunch.

Serve immediately with extra lemon wedges on the side and crusty bread if desired to mop up the broth.
