Ingredients for Keto Creamy Salmon Soup

• 400–500 g salmon (skinless fillet, cut into cubes)
• 1 tbsp butter
• 1 tbsp olive oil
• 1 small onion (or ½ tsp onion powder for fewer carbs)
• 2 garlic cloves
• 500 ml fish or vegetable broth (unsweetened)
• 200 ml heavy cream (33%+)
• 150 g broccoli or cauliflower (finely chopped)
• Salt and pepper to taste

Optional:

• Dill or parsley
• Lemon zest (a small pinch)
• Smoked paprika (a tiny pinch)

Instructions

1. Sauté the aromatics: In a medium pot, melt the butter together with the olive oil over medium heat. Add the finely diced onion (or onion powder later) and minced garlic. Sauté for about 2 minutes until fragrant and slightly softened. This creates a flavorful base without browning, keeping the soup delicate.
2. Add the vegetables: Add the finely chopped broccoli or cauliflower into the pot. Sauté for 2 minutes to coat the vegetables in the aromatic butter mixture and begin softening them.
3. Pour in the broth: Add the fish or vegetable broth and bring it to a gentle boil. Reduce heat and simmer for 7–8 minutes until the vegetables are tender and easily pierced with a fork.
4. Add the salmon: Gently place the salmon cubes into the simmering soup. Cook for exactly 5 minutes — salmon cooks quickly, and keeping the cook time short ensures a tender, flaky texture without drying out.
5. Finish with cream and seasoning: Pour in the heavy cream and stir gently to combine. Add salt, pepper, fresh herbs, a hint of lemon zest, or smoked paprika if desired. Warm the soup for 1–2 minutes, but do not boil after adding cream — this preserves smoothness and prevents separation.
6. Serve hot and garnish with fresh dill or parsley.

⚠️ Mistakes to Avoid

• Overcooking the salmon — it becomes dry and tough, losing its delicate flake.
• Boiling after adding cream — high heat can cause separation and graininess.
• Cutting vegetables too large — small pieces cook evenly and blend with the creamy base.
• Using sweetened broth — adds unwanted carbs and disrupts the flavor balance.
• Adding lemon juice too early — acidity can cause cream to curdle; zest is safer.

Storage & Meal Prep 🧊

• Store in the fridge for up to 3 days.
• Do not freeze if using cream — texture may split after thawing.
• Reheat on low heat to protect the salmon’s tenderness and avoid curdling.
• Prepare vegetables ahead for faster weekday cooking.
