Fortunately, there are simple and effective ways to reduce that unwanted fishy flavor while keeping the rich taste and nutrients intact.

From understanding why salmon can taste this way to practical cooking techniques and flavor-enhancing ingredients, you’ll learn how to transform your salmon soup into a crowd-pleasing dish. Whether you’re a beginner or an experienced cook, these tips will help you create a balanced and flavorful meal every time.
Why Does Salmon Soup Sometimes Taste Fishy?
The fishy taste in salmon soup often stems from oxidation and improper handling of the fish. When salmon is exposed to air for too long or not stored correctly, it can develop a strong odor and taste. Additionally, overcooking salmon or failing to use fresh herbs and acids can intensify this flavor instead of masking it.
But don’t worry—this issue is fixable with the right techniques, which we’ll discuss in detail. First, let’s take a closer look at the causes of fishiness in salmon and how to address them.
Understanding the Fishy Taste in Salmon
1. What Causes the Fishy Smell and Taste?
The fishy smell in salmon is caused by a compound called trimethylamine (TMA). This compound forms as fish begins to break down after being caught. The longer salmon sits, the more TMA accumulates, resulting in that distinctive odor.
- Fresh salmon has little to no fishy smell.
- Older or improperly stored salmon develops stronger odors due to TMA buildup.
2. Types of Salmon and Their Impact on Flavor
Not all salmon tastes the same. The flavor and aroma depend on the type of salmon you choose:
- Atlantic Salmon – Mild flavor, often farm-raised, making it a good choice for soups.
- Sockeye Salmon – Richer and oilier, with a stronger taste. Best for those who enjoy bold flavors.
- Coho Salmon – Balanced flavor and firm texture, great for soups.
- Pink Salmon – Light flavor, but can turn fishy if not super fresh.
3. How Freshness Affects the Taste
Freshness plays a huge role in the taste of salmon soup. Always look for:
- Bright pink or orange flesh without discoloration.
- Firm texture that springs back when touched.
- Mild, ocean-like scent rather than a strong fishy smell.
Pro Tip: If you’re unsure about the freshness of your salmon, give it a quick sniff. If it smells overly fishy, it’s best to avoid using it in soups.
Prepping Salmon to Reduce Fishiness
1. Selecting the Freshest Salmon
The first step to reducing the fishy taste in salmon soup is choosing the freshest fish possible. Fresh salmon should have clear, bright eyes if you’re buying a whole fish, and the flesh should appear vibrant and moist. Avoid salmon with dull, dry patches or an overpowering odor. Frozen salmon can also work well, but it’s essential to thaw it properly by leaving it in the refrigerator overnight rather than using a microwave or warm water. This slow thawing process prevents the breakdown of proteins, which can contribute to stronger odors.
2. Proper Cleaning and Deboning Techniques
Cleaning salmon thoroughly is another important step in minimizing its fishy flavor. Rinse the fillets under cold water to remove surface bacteria and residual blood. Be sure to remove the skin if you find it too oily, as it can sometimes intensify the fishy aroma when cooked. Use kitchen tweezers to remove any pin bones that might remain in the flesh. Removing bones ensures that the soup’s texture is smooth and prevents bitterness caused by marrow seepage.
3. Marinating Techniques to Neutralize Fishy Odors
Marinating salmon in acidic ingredients can significantly reduce its fishiness. A mixture of lemon juice, vinegar, or buttermilk works wonders in breaking down TMA compounds that cause the odor. Simply soak the salmon in the marinade for 15–30 minutes before cooking, but don’t overdo it, as prolonged exposure to acid can start to “cook” the fish, similar to ceviche. For added flavor, include garlic, ginger, or fresh herbs in the marinade.
Cooking Techniques to Minimize Fishiness
1. Blanching Salmon Before Cooking
Blanching salmon briefly in boiling water can remove surface oils and impurities that contribute to the fishy smell. To blanch, boil water with a splash of vinegar or lemon juice, submerge the salmon for 1–2 minutes, and then transfer it immediately to an ice bath to stop the cooking process. This technique firms up the flesh while eliminating surface odors, making it ideal for soups.
2. Balancing Ingredients with Aromatic Herbs and Spices
Aromatics like garlic, onions, ginger, and celery can mask strong smells while enhancing the overall flavor. Herbs like dill, parsley, and cilantro also provide freshness, balancing the richness of the fish. Spices such as paprika, turmeric, and cumin can add depth and complexity, making the soup taste more inviting without overpowering the salmon’s natural flavor. Adding a bay leaf while simmering also helps absorb unwanted odors.
3. Simmering Versus Boiling: The Right Approach for Soup
One of the most common mistakes when making salmon soup is boiling the fish too aggressively, which releases oils and intensifies the fishy smell. Instead, simmer the soup gently over low heat. This slower cooking process preserves the flavor and texture of the salmon while preventing the release of excess oils that can lead to unpleasant odors. If using cream or milk in the soup, add it toward the end to avoid curdling, which can also impact taste and appearance.
Key Ingredients That Counteract Fishy Flavors
1. Adding Citrus for Freshness
Citrus fruits like lemon, lime, and orange are excellent at neutralizing fishy odors in salmon soup. The acidity helps break down the compounds responsible for the smell, leaving behind a clean and refreshing taste. Adding a squeeze of lemon juice to the broth just before serving enhances the flavor without overpowering the soup. Lemon zest can also be sprinkled on top as a garnish for an extra burst of brightness.
2. Incorporating Dairy or Cream-Based Ingredients
Creamy ingredients such as heavy cream, milk, or even coconut milk can soften strong fishy flavors. Dairy products add richness and create a smooth texture, making the soup more appealing. For a Scandinavian-style salmon soup, try adding a splash of cream or a dollop of sour cream to balance the flavors. Coconut milk works well in Asian-inspired versions, providing a subtle sweetness that complements the fish.
3. Enhancing Flavor with Fresh Herbs Like Dill and Parsley
Fresh herbs are essential for reducing fishy tastes and adding layers of flavor. Dill, parsley, cilantro, and thyme are particularly effective in masking unwanted odors. Dill, in particular, pairs exceptionally well with salmon and provides a hint of sweetness. Adding herbs toward the end of cooking preserves their aroma and prevents them from becoming too bitter. For an extra touch, use fresh herb sprigs as a garnish when serving.
Alternative Soup Recipes for Less Fishy Taste
1. Creamy Salmon Chowder
A rich and hearty salmon chowder combines potatoes, cream, and vegetables to create a comforting dish with minimal fishiness. The cream base helps neutralize odors, while ingredients like celery, garlic, and thyme add depth. For best results, use pre-blanched salmon to avoid releasing excess oils into the broth.
2. Scandinavian-Inspired Salmon Soup
This classic recipe features a light and creamy broth with carrots, leeks, and potatoes. It often includes dill and a splash of lemon juice, making it perfect for those who want a milder fish flavor. Adding a small amount of butter at the end enhances the richness without overpowering the soup.
3. Thai Coconut Salmon Soup
For a unique twist, try a Thai-inspired salmon soup made with coconut milk, lemongrass, and ginger. The combination of citrus and spice effectively masks fishy aromas, creating a vibrant and flavorful dish. This recipe pairs well with rice or noodles for a complete meal.
Common Mistakes That Make Salmon Soup Fishier
1. Overcooking the Salmon
Overcooking salmon releases oils and proteins that intensify the fishy smell. To avoid this, add the salmon toward the end of cooking and simmer it gently until just cooked through. This preserves the delicate texture and prevents the soup from becoming overly greasy.
2. Using Low-Quality Fish
Low-quality or previously frozen salmon often has higher levels of TMA, leading to stronger odors. Always opt for fresh, high-quality fish from a trusted source. If frozen salmon is your only option, make sure to thaw it properly in the refrigerator and rinse it thoroughly before cooking.
3. Skipping Aromatics and Flavor Enhancers
Neglecting to include aromatic vegetables, herbs, and acids can leave the fishy smell unchecked. Garlic, onions, and ginger should always be used as a base, while ingredients like lemon juice and vinegar help balance the flavor. Don’t underestimate the power of spices to add complexity and mask unwanted odors.
Pro Tips for Serving Salmon Soup
1. Pairing with Fresh Bread or Crackers
Serving salmon soup with fresh, crusty bread or crisp crackers can elevate the dining experience. Bread, especially sourdough or rye, helps balance the richness of the soup and provides a satisfying texture contrast. Crackers, on the other hand, can add a crunchy element, making each bite more enjoyable. Toasted garlic bread or herbed baguettes are also excellent choices for pairing.
2. Garnishing for Better Presentation
A visually appealing dish can enhance the overall enjoyment of the meal. Garnish your salmon soup with freshly chopped dill, parsley, or chives for added color and flavor. Thin slices of lemon or lime placed on the side of the bowl can give it a gourmet touch. You can also add a swirl of cream on top for a creamy texture and a sprinkle of black pepper or paprika to make the dish pop. For an extra boost of flavor, try adding crumbled feta or grated Parmesan cheese as a finishing touch.
3. Storing and Reheating Tips
Proper storage is crucial for maintaining the freshness and flavor of salmon soup. Always let the soup cool to room temperature before transferring it to an airtight container. Store it in the refrigerator for up to 3 days or freeze it for up to 2 months. When reheating, use low heat and stir gently to prevent the salmon from breaking apart or becoming overcooked. If the soup thickens in the fridge, add a splash of broth or cream to bring it back to the desired consistency.
