Ingredients Needed

Fresh Flounder (or other white fish) – 1 to 1.5 pounds: The main ingredient, with mild and sweet flavor. Flounder’s delicate flesh will break down into tender pieces that make the soup’s texture fantastic.
Olive oil – 1 tablespoon: For sautéing the veggies and adding richness to the broth without overpowering the fish.
Yellow onion – 1 medium, finely chopped: The sweet base flavor for your soup.
Carrots – 2 medium, peeled and sliced: Adds a subtle sweetness and color contrast to the broth.
Celery – 2 stalks, chopped: Essential for that classic, aromatic depth.
Garlic – 2 cloves, minced: A little garlic goes a long way in flavoring the broth.
Potatoes – 2 medium, peeled and diced: They’ll thicken the soup slightly and give it a creamy texture when they break down.
Tomatoes – 2 medium, diced (or 1 can of diced tomatoes): For a touch of acidity and added depth of flavor.
Vegetable or fish stock – 4 cups: A light base that will carry all the flavors without overwhelming them.
Lemon juice – 2 tablespoons: Brightens the flavor and enhances the freshness of the fish.
Herbs – 1 teaspoon dried thyme, 1 bay leaf: These two elements add a fragrant, earthy note to the soup.
Salt and pepper – To taste: For seasoning and balancing the flavors.

Cooking Instructions

Now that we’ve gathered all our ingredients, it’s time to get cooking! Here’s the step-by-step guide for creating your flounder soup:

Prep the fish: Start by cleaning the flounder (if necessary). Remove the bones and skin, and cut the fish into bite-sized pieces. Set them aside for later.
Sauté the vegetables: In a large pot, heat the olive oil over medium heat. Add the chopped onion, carrots, and celery. Cook, stirring occasionally, for about 5-7 minutes, until the vegetables have softened and the onions become translucent.
Add garlic and tomatoes: Stir in the minced garlic and diced tomatoes. Cook for another 2-3 minutes to release the garlic’s fragrance and allow the tomatoes to break down slightly.
Add stock and seasonings: Pour in the vegetable or fish stock, and stir in the thyme, bay leaf, salt, and pepper. Bring the mixture to a gentle boil, then reduce the heat and let it simmer for about 15 minutes. This allows the flavors to meld together.
Add potatoes and fish: Toss in the diced potatoes and gently stir in the flounder pieces. Let the soup simmer for another 10-15 minutes, or until the potatoes are tender and the fish is cooked through.
Finishing touches: Add the lemon juice and adjust the seasoning with more salt and pepper if needed. Remove the bay leaf before serving.
Serve and enjoy: Ladle the soup into bowls, garnish with fresh parsley (optional), and enjoy a comforting, nutritious meal.

Ingredient Insights

Understanding the ingredients and how they contribute to the soup’s flavor is key to making the best version. Here are a few insights:

Flounder: This mild fish is often used in light soups because of its tender, flaky texture and subtle flavor. Unlike stronger-tasting fish like salmon or tuna, flounder won’t overpower the broth, allowing the other ingredients to shine.
Stock: Using a good-quality vegetable or fish stock makes a huge difference in the depth of the broth. Homemade stock is ideal if you have the time; otherwise, store-bought is perfectly fine. Fish stock, if available, will provide an even deeper flavor profile.
Herbs: Thyme and bay leaves are classic additions to any fish soup, giving it a savory, earthy aroma. Fresh herbs can also be used for a more vibrant flavor if you prefer.
Lemon: The acidity from lemon juice cuts through the richness of the fish, balancing the overall flavor and bringing out the freshness of the soup.

Expert Tips

Don’t overcook the fish: Since flounder is delicate, it’s important to avoid overcooking it. Once the fish is added to the soup, keep an eye on it-just a few minutes of simmering is all it needs to become tender.
Make it ahead: Fish soups often taste even better the next day. If you can, make it in advance and let it sit overnight in the fridge to let the flavors develop.
Adjust the texture: If you want a creamier soup, you can blend a portion of the soup base (the potatoes, vegetables, and stock) and return it to the pot before adding the fish.
Use fresh herbs: While dried herbs work fine, fresh thyme or parsley can add a brighter, fresher flavor to the soup.

Recipe Variations

This recipe is easily customizable based on your preferences or what you have on hand. Here are some ways to mix it up:

Spicy version: Add some red pepper flakes, chopped jalapeños, or a dash of hot sauce to give your soup a spicy kick.
Creamy flounder soup: Stir in a splash of heavy cream or coconut milk near the end of cooking for a richer, creamier broth.
Add greens: For an added nutritional boost, toss in a handful of spinach, kale, or Swiss chard just before serving.
Different fish: If you can’t find flounder, other mild white fish like sole, cod, or tilapia work well in this recipe.
Asian-inspired: Add a splash of soy sauce, a sprinkle of ginger, and a few mushrooms for an Asian twist on the flavor profile.
