Ingredients Overview

Let’s break down the simple, bold ingredients that bring this vibrant soup to life.

White Fish Fillets

Use firm, flaky fish like:

• Cod

• Halibut

• Tilapia

• Haddock

Tips:

• Cut into bite-sized pieces for even cooking.

• Avoid overcooking — fish should be tender, not falling apart.

Fresh Lemon Juice and Zest

Lemon is the star flavor here. It adds brightness and cuts through the richness of the broth.

Use both juice and zest for a layered lemony flavor.

Aromatics

Build the base with:

• Garlic (3–4 cloves) – for depth

• Fresh ginger (1 tbsp grated) – for warmth and complexity

• Onion or shallots – adds sweetness

Chili Heat

Add a spicy kick with:

• Red pepper flakes

• Fresh red chili (sliced)

• Chili garlic paste or Sambal oelek

Adjust to your heat preference.

Broth

Use fish stock, chicken broth, or vegetable broth as your base.

Low-sodium broth is best — you’ll season as you go.

Vegetables (Optional but Recommended)

Boost texture and nutrition with:

• Cherry tomatoes – add sweetness and acidity

• Carrots – thinly sliced or julienned

• Spinach, kale, or bok choy – stirred in at the end

• Celery – for classic soup depth

Herbs & Seasoning

• Fresh parsley, cilantro, or dill

• Bay leaf

• Salt and black pepper

• Olive oil – to sauté aromatics

Step-by-Step Instructions

1. Sauté the Aromatics

In a large pot, heat 1 tbsp olive oil over medium heat.

Add:

• 1 chopped onion or 2 shallots

• 3 cloves minced garlic

• 1 tbsp grated ginger

• 1 tsp red pepper flakes (or more to taste)

Cook for 3–4 minutes until fragrant and translucent.

2. Add Broth and Simmer

Pour in:

• 6 cups fish, chicken, or vegetable broth

• Zest of 1 lemon

• 1 bay leaf

• Salt and pepper to taste

Bring to a simmer for 10 minutes to allow flavors to meld.

3. Add Vegetables

If using:

• Add 1 cup cherry tomatoes, halved

• Add 1 sliced carrot or celery stick

Simmer another 5–7 minutes until vegetables are tender.

4. Add Fish and Lemon Juice

Gently stir in:

• 1 lb white fish, cut into 2-inch chunks

• Juice of 1 large lemon (about 2 tbsp)

Simmer on low for 5–7 minutes, just until the fish flakes easily.

Optional: Stir in a handful of spinach or kale in the last 2 minutes.

5. Taste and Finish

Remove from heat and discard bay leaf. Taste and adjust:

• More lemon juice for tang

• Salt or chili for balance

• Olive oil drizzle for richness

Sprinkle with fresh herbs and serve hot.

Tips, Variations & Substitutions

Pro Tips

• Don’t boil once fish is added — gentle simmering keeps it tender.

Flavor Variations

• Thai-Inspired: Add lemongrass, lime leaves, and a splash of coconut milk.

• Mediterranean: Add diced potatoes, olives, and oregano.

• North African: Use harissa paste, cumin, and coriander.

Substitutions
