Ingredients

• Fish & Protein
• 1.5 lbs firm white fish fillets: Cod, haddock, pollock, snapper, or tilapia are excellent choices. Look for fresh, flaky fish that will hold its shape when gently simmered.
• Why we avoid certain fish: We skip overly oily fish (like mackerel) or very delicate flatfish (like sole) because they can break down too much or make the broth taste too "fishy" in this style of soup.
• Vegetables & Aromatics
• 2 tbsp olive oil: For sautéing and building the flavor base.
• 1 medium yellow onion: Chopped, for a sweet aromatic foundation.
• 2 stalks celery: Chopped, adding depth and crunch.
• 2 medium carrots: Chopped, for sweetness and color.
• 3-4 cloves garlic: Minced, for that essential Mediterranean aroma.
• 2 medium potatoes: Such as Yukon Gold or red potatoes, cut into 1/2-inch cubes. They add body and heartiness.
• Optional extra veg (small notes): Feel free to toss in a handful of chopped zucchini or bell pepper with the carrots, or a couple of handfuls of fresh spinach at the very end.
• Broth, Tomato & Seasoning Base
• 4 cups (32 oz) low-sodium vegetable or seafood stock: Seafood stock enhances the flavor, but vegetable stock works beautifully too. If you absolutely must, chicken stock can be used, but it will alter the flavor profile.
• 1 (14.5 oz) can crushed tomatoes or diced tomatoes: Crushed tomatoes blend in more smoothly, diced add more texture.
• 1 tsp dried thyme: A classic Mediterranean herb.
• 1 bay leaf: For subtle, savory notes.
• 1/2 tsp sweet paprika or a mild warm spice blend (e.g., a pinch of oregano and a tiny pinch of cumin): Adds warmth without heat.
• Salt and freshly ground black pepper: To taste, essential for balancing flavors.
• Finishing Touches
• 2 tbsp fresh lemon juice: Brightens all the flavors and balances the richness.
• 1/4 cup fresh parsley (and/or cilantro): Chopped, for freshness and color.
• Optional red pepper flakes: A pinch for a subtle kick if you like a little heat.
• Optional tiny splash of cream or extra-virgin olive oil: A small swirl at the end for a touch of richness and silky texture – this is purely optional and not a second recipe.

Directions

1. Prep the Fish and Veggies
   1. Start by patting your fish fillets dry with paper towels. Cut them into roughly 1-inch chunks. Season them lightly with salt and pepper, then set aside. This helps the fish absorb flavor.
   2. Next, chop your onion, celery, carrots, and potatoes into even, bite-sized pieces. If using any optional extra veggies like zucchini or bell pepper, chop them now too. Your kitchen should already be smelling fresh and vibrant!
2. Build the Flavor Base
   1. Heat the olive oil in a large, heavy-bottomed pot or Dutch oven over medium heat. Add the chopped onion, celery, and carrots. Sauté them gently for 5-7 minutes, stirring occasionally, until they soften and the onion becomes translucent and lightly golden.
   2. Stir in the minced garlic and paprika (or mild spice blend). Cook for just 1 minute more, until fragrant. Be careful not to burn the garlic – it should smell sweet, not acrid.
   3. Pour in the crushed tomatoes, dried thyme, and bay leaf. Add a splash (about 1/4 cup) of your stock to deglaze the pot, scraping up any browned bits from the bottom. This adds incredible depth of flavor. Let it simmer for 2-3 minutes, allowing the tomatoes to begin breaking down.
3. Simmer the Broth & Veggies
   1. Add the remaining stock and the cubed potatoes to the pot. Bring the soup to a gentle simmer, then reduce the heat to low, cover, and let it cook for 10-15 minutes, or until the potatoes are just tender when pierced with a fork.
   2. At this stage, taste the broth and adjust the salt and pepper as needed. It's important to season early so the broth itself is flavorful before the fish goes in.
4. Poach the Fish Gently
   1. Once the potatoes are tender, gently add the seasoned fish pieces to the simmering broth. Do not stir vigorously, as this can break up the fish. Just nestle them into the liquid.
   2. Continue to simmer gently, uncovered, for 5-8 minutes, depending on the thickness of your fish chunks. The fish is cooked when it turns opaque and flakes easily with a fork. Overcooking will make the fish tough and dry, so keep an eye on it!
   3. If you're adding quick-cooking vegetables like spinach, stir them in during the last 2 minutes of cooking until just wilted.
5. Finish with Lemon & Herbs
   1. Remove the pot from the heat. Take out and discard the bay leaf.
   2. Stir in the fresh lemon juice and chopped parsley (and/or cilantro). Give the soup one final taste and adjust the seasoning again if necessary, adding more salt, pepper, or lemon juice to brighten the flavors.
   3. The soup should have a vibrant, fresh taste with tender fish and vegetables in a light, aromatic broth. You did it right if it smells amazing and tastes perfectly balanced!
