Can You Vary The Recipe With Other Ingredients?

  2. Gluten-Free Ensure your broth and any added seasonings are gluten-free. Use cornstarch or a gluten-free flour blend if the recipe calls for a roux or thickener.
  3. Whole30 Stick to Whole30-compliant ingredients. Use homemade broth, and avoid legumes, grains, dairy, and sweeteners. Increase the veggies, and add a protein source like chicken or fish.
  4. Vegetarian Replace fish with hearty vegetables such as mushrooms, eggplant, or tofu for a protein boost. Use a rich vegetable broth to impart depth of flavor.
  5. Vegan Follow the vegetarian tips and also ensure to omit any animal-derived ingredients like butter. Use plant-based oils for sautéing, and consider seaweed for a ‘fishy’ flavor.

Can I Make Soup In A Slow Cooker Or Instant Pot?

Slow Cooker

  • Add the prepared fish to the slow cooker with enough salted water to cover. Cook on low for 2-3 hours or until the fish flakes easily.
  • Remove the fish, debone, and de-skin, then sieve. Return the sieved fish to the slow cooker.
  • Simmer the sliced onion in milk in a separate pan for ten minutes. Remove the onion, add white roux to the milk, stir until well mixed, then add to the slow cooker.
  • Cook on low for another hour. Season to taste before serving.

Instant Pot

  • Set the Instant Pot to sauté mode. Cook the fish in the pot with enough salted water to cover it until it flakes easily. This should take around 10-15 minutes.
  • Turn off the sauté mode. Remove the fish, debone, and de-skin, then sieve. Return the sieved fish to the pot.
  • Simmer the sliced onion in milk in a separate pan for ten minutes. Remove the onion, add white roux to the milk, stir until well mixed, then add to the pot.
  • Close the lid, seal the vent, and set it to manual high pressure for 10 minutes.

Can I Use Store Broth, Or Should I Make My Own?

You can certainly use store-bought broth for convenience, which can still yield a delicious soup. Look for a high-quality fish or seafood broth for the best flavor. The vegetable broth could also be used as a substitute.

However, making your own broth at home provides several advantages:

  • Flavor: Homemade broth tends to have a fresher, deeper flavor that can significantly enhance the overall taste of your soup.
  • Control over Ingredients: When you make your own broth, you have complete control over what goes into it. This means you can avoid preservatives, excess sodium, or any ingredients you may be allergic to. 
  • Economical and Sustainable: You can use fish bones, heads, and other scraps that might otherwise go to waste, making it an economical and environmentally-friendly option.

How To Serve ?

  • Warm Bowls: Serve your soup in warm bowls to keep it hot for longer. Warm them in the oven at a low temperature or rinse them with hot water before serving.
  • Portion Sizes: Make sure to ladle an appropriate amount into each bowl, allowing for both the liquid and the solid ingredients. You want to fill the bowls and avoid spills.
  • Garnish: A well-chosen garnish can elevate the presentation of your soup. This could be a sprig of fresh herbs, a slice of lemon, a swirl of cream, or a sprinkle of fresh, chopped herbs.
  • Accompaniments: Depending on the type of soup, it may be served with a side of crusty bread, a salad, or a sandwich. A lighter soup pairs well with a heartier main, while a rich, creamy soup might be best with a simple green salad or bread.
  • Table Setting: Soup is usually served as the first course in a formal meal, but if it’s the main event, make sure your table setting is comfortable for a leisurely meal. Warm colors and soft lighting create a cozy, inviting atmosphere.

Perfect Side Dishes

  • Crusty Bread: A slice of fresh, crusty bread is always a welcome addition to soup. It’s perfect for dipping and helps you scoop up every last drop.
  • Grilled Cheese Sandwich: This classic side dish for tomato soup can also work great with fish soup. The crispy, gooey sandwich can offer a nice textural contrast.
  • Green Salad: A light, crisp salad with a tangy vinaigrette can complement the creaminess of a fish soup well. Include plenty of fresh, crunchy vegetables for a satisfying contrast.
  • Roasted Vegetables: If your soup is light, a side of roasted vegetables can help make the meal more filling. Consider vegetables like carrots, potatoes, or Brussels sprouts.
  • Coleslaw: A fresh and crunchy coleslaw can offer a refreshing contrast to a hot, creamy fish soup. You could go for a classic coleslaw or mix it up with ingredients like apple, fennel, or beetroot.
  • Quinoa Salad: A quinoa salad can be a hearty, nutritious side that pairs well with fish soup. Add your favorite veggies, some fresh herbs, and a simple dressing for a flavorful side dish.
  • Garlic Bread: Garlic bread would be an excellent choice for a heartier option. The flavor of garlic and butter works well with the delicateness of fish soup.
  • Seafood Bruschetta: For an elegant meal, serve your fish soup with bruschetta topped with a light seafood mix, like shrimp or crab.

Storage And Make Ahead

  • Refrigeration: Store leftover fish soup in an airtight container in the refrigerator for up to 3 days. Ensure it cools completely before refrigerating.
  • Freezing: Fish soup can be frozen for up to 3 months. Cool it completely, then transfer to freezer-safe containers, leaving some space for expansion.
  • Thawing: Thaw frozen fish soup overnight in the refrigerator or gently reheat from frozen on the stovetop over low heat.
  • Make Ahead: Fish soup is perfect for making ahead. Prepare the soup, excluding delicate ingredients like fish or seafood, and refrigerate. Add these ingredients and simmer just before serving for the freshest taste.

What Can We Do With Leftovers?

  • Fish Stew: Add some diced potatoes, carrots, or other hearty vegetables, and let simmer until tender to turn your soup into a chunky stew.
  • Fish Pie Filling: Use your leftover soup as the base for a comforting fish pie. Top with mashed potatoes and bake until golden.
  • Pasta Sauce: Thicken the soup with a bit of cream and toss with pasta for a quick seafood spaghetti or linguini.
  • Fish Tacos: Strain the solid ingredients from the soup and use them as a filling for fish tacos.
  • Fish Cakes: Again, strain the solids, mix them with mashed potatoes, form them into patties, and pan-fry for delicious fish cakes.
  • Risotto: Use the leftover soup as the liquid base when making risotto, adding it slowly until the rice is creamy and cooked.
  • Seafood Paella: Similar to the risotto idea, the soup can also provide a flavor base for seafood paella.
  • Baked Fish: Use the leftover soup as a marinade or cooking liquid for baking fresh fish.


  • Freshness First: Start with the freshest fish you can find. It makes a huge difference in the flavor of your soup.
  • Layered Flavor: Build flavor by sautéing onions, garlic, and other aromatics before adding liquid. This adds depth to the soup.
  • Use Fish Stock: If possible, use homemade fish stock for a richer taste. If not, a good quality store-bought version will do.
  • Add Fish Last: Add delicate fish towards the end of cooking to prevent it from overcooking and becoming tough.
  • Finish with Fresh Herbs: Add a handful of chopped fresh herbs like parsley or dill just before serving for a burst of fresh flavor.

Indulge in a delightful bowl of Fish Soup – a harmonious blend of succulent cod or halibut, sliced onions, and creamy milk simmered to perfection. This comforting soup offers a savory, nutritious escape for your taste buds.

Ingredients List

  • 1 lb. 1 Cod Or Halibut

  • 1 quart 1 Milk

  • 1 sliced 1 Onion

  • 1 tablespoon 1 White Roux

Step-By-Step Directions

  • Preparation Steps: Start by cleaning your fish, ensuring all scales and innards are removed. Keep a pot of salted water ready.
  • Cooking: Place the cleaned fish into the boiling salted water. Cook until the fish becomes tender and flakes easily with a fork. This process ensures all the delicious flavors are seeped into the water, creating a rich, flavorful base.
  • Draining and Sieving: Once the fish is fully cooked, drain it from the broth. Proceed to remove the bones and skin carefully. Use a sieve to rub the cooked fish through, ensuring you have a smooth, boneless mixture.
  • Creating the Milk Base: Place the sliced onion into the milk in a separate pan. Allow this to boil for ten minutes. This process infuses the milk with a subtle onion flavor, adding complexity to your soup. After boiling, remove and discard the onion.
  • Adding the Roux: Prepare the white roux according to the instructions (see p. 12). Gradually add it to the milk, stirring continuously to ensure it mixes evenly. This thickens the soup and gives it a rich, velvety texture.
  • Blending: Add the sieved fish to the mixture once the milk and roux are well combined. Stir thoroughly to ensure the fish is evenly distributed throughout the soup.
  • Final Touches: Now it’s time to season your soup. Taste the soup first, then add salt and pepper or other preferred seasonings gradually, stirring and tasting as you go.
  • Serving: Serve your fish soup hot. You can garnish with fresh herbs, a swirl of cream, or a squeeze of lemon. Accompany it with crusty bread or a light salad for a complete meal.
  • Additional Options: This basic fish soup can be varied with different ingredients. Consider adding sautéed vegetables, different kinds of fish, or a splash of white wine for extra flavor.
  • Soup pot or large saucepan
  • Cutting board
  • Sharp knife
  • Stirring spoon
  • Measuring spoons (for the roux)
  • Ladle (for serving)
  • Soup bowls (for serving)


  • Fish Selection: Opt for fresh cod or halibut to ensure the best flavor and texture. Frozen fish can also be used, but thaw it thoroughly before cooking.
  • Milk Variations: Experiment with different milk types like whole, low-fat, or even coconut milk for unique flavor profiles.
  • Roux Tip: To prepare the white roux, melt butter in a saucepan and whisk in an equal amount of all-purpose flour until smooth. Cook over low heat until it forms a pale, creamy mixture.
  • Seasoning: Enhance the soup’s taste with herbs like thyme, parsley, or bay leaves. Remember to add salt and pepper to your preferred taste.
  • Garnish Ideas: Sprinkle some freshly chopped herbs or a dash of paprika on top for an appealing presentation.
  • Accompaniments: Serve the Fish Soup with crusty bread or oyster crackers to complement its rich flavors.
  • Storage: Refrigerate any leftovers promptly and consume them within a day or two for the best taste and quality.
