Ingredients
- 2 tablespoons butter
- 1 medium yellow onion, diced into 1/4-inch cubes
- 2 stalks celery stalks, sliced into 1/4-inch half-moons
- 1.5 pounds floury potatoes (Russets), cut into 1/2-inch cubes
- 4 cups fish stock or chicken stock
- 1 cup heavy cream
- 1 pound cod or haddock fillets, cut into 1-inch chunks
- ½ pound mussels, debearded and rinsed
- ½ pound large shrimp, peeled and deveined
- 1 teaspoon fresh thyme leaves
Instructions
- 1
Peel the onion, cut it in half lengthwise from root to tip, place each half flat-side down, and slice crosswise into 1/4-inch pieces that look like small half-moon shapes.
- 2
Hold each celery stalk upright and slice it straight down at an angle into 1/4-inch-thick half-moons that resemble crescent moons.
- 3
Hold each potato and cut it in half, then cut each half into pieces roughly the size of a dice — about 1/2 inch on all sides.
- 4
Place the cod fillet skin-side down and cut it straight down across the grain into chunks about the size of a grape, roughly 1 inch wide.
- 5
Pull the dark stringy beard off each mussel by grasping it between your thumb and forefinger and yanking it toward the hinge, then rinse each mussel under cold running water.
- 6
Place a large heavy-bottomed pot over medium heat and add 2 tablespoons of butter, swirling the pan until the butter is completely melted and foaming, about 45 seconds.
- 7
Add the diced onion and celery to the hot butter and stir once every 30 seconds for 4 minutes, until the onion turns translucent and the vegetables soften slightly.
- 8
Add the potato cubes and 4 cups of stock to the pot, stir once to combine, and bring to a rolling boil over medium-high heat — you'll see large bubbles rapidly breaking the surface.
- 9
Lower the heat to medium and simmer uncovered for 12–15 minutes, until a fork easily pierces the potato pieces and they are mostly tender but not falling apart.
- 10
Pour the 1 cup of heavy cream into the pot and stir gently with a wooden spoon for 20 seconds until completely blended, then sprinkle in 1 teaspoon of fresh thyme leaves.
- 11
Place the cod chunks and shrimp into the pot and stir gently once to distribute them evenly, then simmer over medium heat for 3 minutes until the fish turns opaque white.
- 12
Scatter the rinsed mussels across the top of the chowder without stirring them in, then cover the pot with a lid and simmer for 4–5 minutes until the mussel shells pop open.
- 13
Lift the lid carefully away from you (to avoid the hot steam), discard any mussels whose shells did not open, and taste a spoonful of broth to check if you need salt or pepper.
- 14
Add a pinch of salt and a few grinds of black pepper to the pot and stir gently once to combine, then ladle the chowder into four bowls, dividing the seafood and potatoes equally.
