What You’ll Need (Ingredient Highlights)

Broth creates a more flavorful base than plain water and helps season the fish gently.
Pro Tips Before You Start
Cut the salmon into evenly sized pieces so they cook at the same rate.
Do not overcook the fish or it may become dry and tough.
Keep the liquid at a gentle boil rather than an aggressive rolling boil.
Use a spoon or spatula to lower the fish carefully into the broth to prevent splashing.
How to Make Boiled Fish
Step 1 – Heat the broth
Pour the broth into a pot and add the sliced onions. Bring the liquid to a boil over medium-high heat.
Step 2 – Prepare the salmon
Slice the salmon fillet into 2–3 equal-sized pieces so they fit easily into the pot and cook evenly.
Step 3 – Cook the fish
Carefully lower the salmon into the boiling broth using a spoon. Bring back to a gentle boil and cook for 4–5 minutes until the fish flakes easily with a fork.
What to Serve Them With
Serve the boiled salmon with steamed rice or roasted potatoes for a simple meal.
Pair it with green vegetables like asparagus, broccoli, or green beans.
A fresh salad and lemon wedges also work beautifully alongside the fish.
Variations / Substitutions
Swap salmon for cod, tilapia, or halibut if preferred.
Add garlic, celery, or fresh herbs to the broth for extra flavor.
Use water instead of broth and season lightly with salt and pepper.
Storage & Leftovers
Store leftover fish in an airtight container in the refrigerator for up to 2 days.
Reheat gently to avoid drying out the salmon.
Leftover fish can also be flaked into salads, sandwiches, or rice bowls.
