Creamy Fish Soup Recipe: Silky Broth With Flaky Fish Pieces

This creamy fish soup recipe delivers the perfect balance of silky broth and delicate flaky fish pieces that melt in your mouth. The secret lies in slow simmering fish until it practically falls apart, then blending just enough to create a velvety texture without overpowering the natural ocean flavors.

I developed this version after years of testing—it’s the one that finally convinced even my most skeptical family members to request seconds.

The foundation of this soup starts with a rich fish stock, built by simmering fish bones and aromatics until deeply flavorful. White fish like cod or haddock adds subtle sweetness, while a touch of cream or coconut milk (for a lighter version) creates that signature velvety consistency.

The vegetables—carrots, celery, and onions—provide natural sweetness and structure, ensuring every spoonful is both comforting and balanced.

What you’ll end up with is a soup that’s impossibly smooth yet still packed with flaky fish and tender vegetables. The broth clings to each bite, while the fish pieces stay delicate and melt-in-your-mouth tender.

This is the kind of soup that feels like a hug on a chilly day—warm, nourishing, and impossible to resist.

Serve it with crusty bread for dipping or a sprinkle of fresh herbs for brightness. The recipe scales easily, so you can make a single serving for a light lunch or double it for a hearty family dinner. Let’s get cooking—your taste buds will thank you.

Ingredients for creamy fish soup

Simple ingredients that transform into velvety comfort. The secret is in the slow simmering and blending.

The fish stock is the soul of this soup. Homemade stock made from fish bones and aromatics gives the deepest flavor, but a quality store-bought like Pacific Foods or Knorr works in a pinch. For the fish fillets, cod or haddock are ideal—they stay flaky and absorb flavors beautifully. I like to buy them fresh at Whole Foods or Trader Joe's where they’re always on ice. If you can’t find fresh, frozen works too—just thaw overnight in the fridge. The creaminess comes from heavy cream, but coconut milk makes a delicious lighter alternative that still feels indulgent.

No fresh dill? Dried dill at one-third the amount works, but fresh is worth hunting down—it brightens the whole dish. Running out of fish stock? Clam juice or shrimp stock adds a similar oceanic depth. For the vegetables, baby carrots or pre-diced celery save time, but whole carrots and celery stalks are cheaper and last longer. The butter and olive oil combo gives that rich, golden base—don’t skip it. If you’re watching calories, use half butter and half olive oil instead. And trust me, the lemon juice at the end is non-negotiable—it cuts through the richness and makes everything sing.

This soup tastes even better the next day, so make a double batch and freeze half. Store leftovers in the fridge for 3-4 days or freeze for up to 3 months. I like to portion it into containers with a little extra broth on top to keep it from drying out. For serving, a sprinkle of fresh dill or a drizzle of cream makes it look restaurant-worthy. The broth reduces slightly when reheated, so add a splash of water or stock if it gets too thick.

Step-by-step instructions for creamy fish soup

Here's how to build a velvety fish soup with tender fish pieces that flake apart at the first touch.

Heat the 1 tablespoon olive oil in a large pot over medium heat. Add the 1 whole yellow onion and 1 cup carrots, cooking for 5 minutes until softened. Stir in the 2 whole celery stalks and continue cooking for another 3 minutes until the vegetables begin to release their natural juices.

Add the 3 cloves garlic and cook for 30 seconds until fragrant. Here's the thing—don't let the garlic burn. It should smell sweet and inviting, not bitter. If it starts to darken too quickly, reduce the heat slightly. This aromatic base forms the flavor foundation of your soup, so take your time here.

Pour in the 4 cups fish stock and bring to a gentle simmer. Add the 2 tablespoons butter, stirring until melted and incorporated. Season with the 1 teaspoon salt and ½ teaspoon black pepper, then add the 1 tablespoon lemon juice. Let the broth simmer uncovered for 10 minutes to allow the flavors to meld together.

I like to taste the broth at this stage—it should be flavorful but not overpowering. If it needs more depth, a pinch of salt or a splash of lemon juice can help. The broth should be clear with just a hint of cloudiness from the butter and vegetables. This is your creamy base before we add the rich elements.

Reduce the heat to low and stir in the ½ cup heavy cream and ¼ cup light coconut milk. These ingredients will create the luxurious creaminess promised in the title. Let the soup simmer gently for 5 minutes, stirring occasionally to prevent any scorching at the bottom of the pot.

The soup should now have a velvety appearance with a smooth texture. If you taste it, you'll notice the richness from the cream and the subtle sweetness of the coconut milk. This is where the magic happens—don't rush this step. The gentle simmer ensures the cream doesn't curdle or separate, giving you that perfect, silky consistency.

Add the 12 oz white fish fillets to the simmering soup. Cook for 4-5 minutes until the fish is just opaque throughout and flakes easily with a fork. The fish should be tender but still hold together slightly—it will continue cooking for a minute or two once removed from the heat.

Here's the critical part: don't overcook the fish. It should be delicate and flaky, not falling apart completely in the pot. You want pieces that hold their shape when served but melt in your mouth. Once the fish is cooked, remove it from the pot and set it aside on a plate.

Return the soup to a gentle simmer and stir in the ¼ cup fresh dill. Let it cook for 1 minute to allow the dill to release its bright, fresh flavor. Taste and adjust the seasoning if needed—you might need a little more salt or lemon juice to balance the richness of the cream.

Gently stir the fish back into the soup and let it warm through for 1 minute. Ladle the soup into bowls, making sure each serving gets a generous portion of flaky fish. Garnish with additional dill if desired. Serve immediately with crusty bread to soak up every last drop of that creamy, flavorful broth. The contrast of the warm, creamy soup with the crisp bread is what makes this dish truly special.

Perfect pairings for this recipe

Bread Pairings

Nothing beats the contrast of warm, crusty bread with this creamy fish soup. I love serving it with a baguette sliced into thick pieces for dipping—just toast them in the oven for 3-5 minutes at 375°F until golden and crisp.

For extra indulgence, try a sourdough loaf with its tangy bite cutting through the richness. The bread soaks up every last drop of that velvety broth, making it feel like a complete meal. 🥖

Herb Garnishes

Fresh herbs elevate this soup from homemade to restaurant-worthy. A sprinkle of chopped parsley or fresh dill right before serving adds a pop of color and brightness.

I also like a drizzle of extra virgin olive oil and a pinch of flaky sea salt—it enhances the natural flavors without overpowering. For a bold touch, add a few red pepper flakes if you enjoy heat. These garnishes make the soup look as good as it tastes. ✨

Wine Pairings

A crisp white wine complements the creamy texture and delicate fish flavors beautifully. I reach for a Chardonnay with subtle oak notes—something like La Crema Sonoma Coast Chardonnay—to match the richness without overwhelming it.

For a lighter option, a Sauvignon Blanc from New Zealand, like Cloudy Bay, brings bright acidity that cuts through the cream. Avoid heavy reds or overly oaky whites—they’ll clash with the soup’s delicate balance. 🍷

Lighter Alternatives

If you're watching calories or prefer a lighter touch, swap the heavy cream for Greek yogurt or coconut milk. I’ve also had great success using half-and-half—it still delivers creaminess with fewer calories.
