Soups & Stews
This tuna soup recipe delivers a velvety blend of white beans and tender tuna, elevated by bright lemon zest that cuts through the richness. The secret lies in simmering the broth just long enough to develop depth without overpowering the delicate flavors of the fish.
I perfected this version after years of testing—it’s the kind of soup that transforms a simple lunch into something memorable.
The foundation starts with a robust broth, where canned tuna dissolves into silky perfection while white beans add hearty texture. A splash of lemon zest and a touch of olive oil at the end brighten every spoonful, balancing the soup’s natural richness.
This recipe is designed to be foolproof, with techniques that ensure the tuna stays tender and the broth remains smooth, even when reheated.
What you’ll end up with is a creamy yet light soup that’s packed with protein and flavor—ideal for chilly days or quick weeknight meals. The lemon zest adds a refreshing twist that keeps the dish from feeling heavy, while the white beans provide substance without overpowering the tuna’s natural taste.
Serve with crusty bread or a simple green salad for a complete meal.
For those looking to adapt, you can easily swap the tuna for chickpeas or white beans alone, though the fish remains the star. The recipe scales effortlessly, making it perfect for small gatherings or meal prep. Let’s get cooking—this soup is simpler than it tastes.
Ingredients for tuna soup
Pantry staples meet fresh bright flavors in this velvety tuna soup.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned White Beans 🍲 | 1 ½ cups | Drained and rinsed, cannellini preferred |
| Canned Tuna in Water 🐟 | 2 cans | 5 oz each, drained well |
| Vegetable Broth 💧 | 4 cups | Low-sodium preferred, homemade or quality store-bought |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For richness and finishing |
| Lemon Zest 🍋 | 1 tbsp | Freshly grated, bright and aromatic |
| Fresh Lemon Juice 🍋 | 1 tbsp | From 1 medium lemon |
| Garlic Cloves 🧄 | 2 cloves | Minced for aromatic depth |
| Shallot 🧅 | ½ whole | Finely diced, or substitute 1 small onion |
| Fresh Dill 🌿 | ¼ cup | Chopped, stems removed |
| Heavy Cream 🥛 | ¼ cup | Full-fat for creaminess |
| Salt 🧂 | ½ tsp | Adjust to taste, kosher preferred |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground for best flavor |
| Crusty Bread 🍞 | 4 slices | For serving, optional |
The white beans are the backbone of this soup—cannellini holds its shape best, but great northern works too. Trader Joe's and Whole Foods carry high-quality canned options, but any low-sodium brand in the canned goods aisle will do. For the tuna, wild-caught brands like Wild Planet or Starkist in water (not oil) ensure tender flakes. The vegetable broth should be rich but not salty—homemade is ideal, but even the basic Pacific Foods or Swanson low-sodium versions work. The shallot adds subtle sweetness, so don't skip it—it's the secret to depth.
No fresh dill? Dried dill at one-third the amount works in a pinch, though fresh has that bright, herbal punch. Substituting the tuna? Chickpeas or extra white beans keep it hearty, but the dish loses its signature protein boost. For a dairy-free version, swap the heavy cream for coconut milk or cashew cream, though the texture will be slightly lighter. The lemon zest needs to be fresh—pre-grated zest loses its vibrancy. If you can't zest, 1 tsp lemon extract (plus extra juice) mimics the brightness, though it's not identical. The olive oil should be extra-virgin—cheap oil tastes harsh in the final soup.
This soup tastes even better the next day as flavors meld—reheat gently on low heat, stirring occasionally to prevent skin from forming. Store in an airtight container for 4-5 days in the fridge, or freeze portions for up to 3 months. I like to portion it into single servings before freezing so I can grab and go. The bread? Toast it fresh when serving—it soaks up the soup beautifully, but soggy bread is a crime. Leftovers reheat best with a splash of water or broth to restore creaminess.

Step-by-step instructions for tuna soup with white beans
Here's how to create a velvety, lemon-infused soup that balances protein and freshness perfectly.
Sauté Aromatics in Olive Oil
Heat the 0.25 cup extra-virgin olive oil in a large pot over medium heat until shimmering. Add the 0.5 whole shallot, finely diced, and 2 cloves garlic cloves, minced. Cook for 3-4 minutes until the shallot becomes translucent and the garlic releases its fragrance—this builds the flavor foundation.
Watch closely as the shallot cooks. It should soften without browning, which would add bitterness. If you notice any browning, reduce the heat slightly. The garlic should sizzle gently and become aromatic rather than darken. This step ensures your soup develops depth before adding the beans and tuna.
Build the Bean and Broth Base
Add the 1.5 cups drained canned white beans to the pot and stir to coat them in the oil. Pour in the 4 cups vegetable broth and bring the mixture to a gentle boil over medium-high heat. Once boiling, reduce the heat to medium-low and let it simmer uncovered for 10 minutes to allow the flavors to meld.
During this time, you'll notice the soup develop a subtle richness from the beans. The broth should reduce slightly, intensifying its flavor. If you see any foam forming, skim it off with a spoon—this keeps the soup clean and focused. The beans should soften slightly but remain intact, releasing their creamy texture into the broth.
Incorporate Tuna and Acidic Elements
Gently fold in the 2 cans drained canned tuna in water using a wooden spoon, breaking up any large chunks. Add the 1 tbsp lemon zest and 1 tbsp fresh lemon juice, stirring well to distribute the bright citrus notes. Simmer for an additional 5 minutes to let the lemon flavors infuse without curdling the tuna.
The lemon zest will float on top initially, but stirring helps it disperse evenly. You'll notice the soup brighten in color and aroma—this is the moment the dish transforms from simple to vibrant. The tuna should heat through completely, absorbing the citrus and bean flavors without overcooking. If the soup starts to thicken too much, add 1-2 tablespoons of water to maintain a silky consistency.
Finish with Cream and Fresh Herbs
Remove the pot from heat and stir in the 0.25 cup heavy cream and 0.25 cup chopped fresh dill. Season with the 0.5 tsp salt and 0.25 tsp black pepper, tasting as you go. Let the soup sit off the heat for 2-3 minutes to allow the cream to gently warm and meld with the other ingredients.
The cream will create a luxurious finish, while the dill adds a fresh herbal note that balances the richness. You should taste a harmonious blend of lemon, beans, and tuna with a velvety texture. If the soup needs more brightness, add another ½ teaspoon of lemon juice. For extra depth, a drizzle of extra-virgin olive oil on each serving adds another layer of richness.
Serve with Crusty Bread
Ladle the soup into bowls and serve immediately with the 4 slices crusty bread on the side. The bread should be toasted lightly—just until it's warm and crispy—to complement the soup's creamy texture. Each spoonful should deliver a perfect balance of protein from the tuna and beans, brightness from the lemon, and a velvety finish from the cream.
For an elevated presentation, garnish each bowl with an additional sprinkle of lemon zest and a few chopped dill leaves. The contrast of the warm soup against the cool bread creates an ideal dining experience. This soup holds well for 2-3 days refrigerated, though the lemon zest may lose some brightness over time—best enjoyed fresh.
Pro Tips For Making Tuna Soup
- Drain and Rinse the Tuna: The water from canned tuna is salty and dulls the broth’s flavor—skip the lazy pour-and-go. Drain it, then rinse the fish under cold water to wash away any lingering brine. Trust me, your soup won’t taste like a swimming pool afterward.
- Simmer, Don’t Boil: After adding the beans and broth, keep the heat at a gentle simmer—not a rolling boil. I learned this the hard way when my first batch turned into a mushy bean slurry. Low and slow keeps the texture intact and lets the flavors meld.
- Crush Half the Beans: Leave about half the white beans whole for texture, but crush the other half with a fork or your hands. This creates a creamy base without needing heavy cream, and it actually makes the soup richer. (Yes, even if it looks uneven.)
- Finish with Lemon Zest: Add the lemon zest at the very end, right when you’re serving. The heat breaks down the oils in the zest, so tossing it in early makes the soup taste bitter. A quick sprinkle on top brightens every spoonful—no one will guess it’s just a pinch.
Storing and reheating your tuna soup
Refrigerator Storage
Transfer your tuna soup to an airtight glass container (I use Pyrex with snap-on lids) once it’s cooled to room temperature—never store it hot. The soup keeps its velvety texture for up to 4-5 days in the fridge at 40°F or below.
The lemon zest and dill will retain their brightness for the first 2 days, but the soup’s flavor actually deepens as the ingredients meld. Always leave ½-inch headspace to prevent condensation from diluting the broth. 💫
Freezer-Friendly Tips
Portion the soup into single-serving glass jars or quart-sized freezer bags before freezing. Squeeze out excess air to prevent freezer burn, and label with the date. It stays fresh for up to 3 months—though I’ve found the texture softens slightly after 2 months.
For best results, thaw overnight in the fridge rather than using the microwave. The tuna and beans hold up well, but the cream may separate slightly upon reheating. 🧊
Reheating Like a Pro
For stovetop reheating, transfer the soup to a pot and warm over low-medium heat, stirring occasionally to prevent scorching. Add 1-2 tablespoons of water or broth if it thickens too much.
The ideal temperature is 165°F—use a thermometer to avoid overcooking. If using the microwave, heat in 1-minute intervals on 50% power, stirring between each interval to distribute heat evenly. 🔥
Reviving Texture
If your reheated soup seems too thick, thin it with warm broth (start with 2 tablespoons) until it reaches your desired consistency. For extra richness, stir in 1 teaspoon of olive oil or a splash of heavy cream while reheating.
The lemon zest may lose some vibrancy after reheating, so garnish with fresh zest just before serving to restore brightness. 💛
Bread Pairing Preservation
Toast your crusty bread fresh when serving—it’s best enjoyed within 1 hour of toasting to maintain crispiness. Store any leftover bread in a paper bag at room temperature for up to 3 days.
For extra flavor, rub the bread with a garlic clove before toasting—it pairs perfectly with the soup’s lemony notes. 🍞
Make-Ahead Meal Prep
Double the recipe and freeze half for quick lunches—just reheat and serve. I like to prep 4 individual portions in advance, storing them in glass meal prep containers with tight seals.
The soup reheats beautifully for 3-4 days without losing its creamy texture, making it perfect for busy weeknights. Add a dash of lemon juice before serving to revive the flavors. ✨

Frequently asked questions
Can I use fresh tuna instead of canned in this recipe?
Fresh tuna works but requires careful handling. Use 1 pound of fresh tuna (like yellowfin or albacore), poached or seared first to 145°F (or until opaque), then flaked into the soup. Fresh tuna has a firmer texture, so you may want to add 1 extra tablespoon of cream to maintain richness. Always cook fresh fish thoroughly to avoid foodborne illness.
How do I make this soup vegetarian?
Swap the tuna for 1.5 cups extra white beans (or 1 can chickpeas) and add 1 teaspoon of nori flakes or ½ teaspoon smoked paprika for a seafood-like depth. Boost umami with 1 tablespoon soy sauce or ½ teaspoon miso paste. The lemon and dill keep the dish bright, while the beans provide protein.
Why does my soup turn out too thick or watery?
Thick soup? Simmer uncovered for 5-10 extra minutes to reduce, or stir in 1-2 tablespoons of warm water or broth. Too watery? Let it simmer 5 minutes longer uncovered, or stir in 1 tablespoon of cornstarch mixed with 2 tablespoons cold water and cook for 2 minutes. For best results, follow the recipe's simmer times precisely.
Can I make this soup in an Instant Pot or pressure cooker?
Yes! Sauté shallots and garlic as directed, then add beans and broth. Pressure cook on high for 5 minutes, quick-release, and stir in tuna, lemon, cream, and dill. The high heat preserves the tuna's texture, but reduce simmer time to 3 minutes after adding tuna to avoid overcooking.
What’s the best way to reheat leftovers without breaking the texture?
Reheat gently on the stovetop over low heat, stirring frequently. Add 1 tablespoon of water or broth if it thickens too much. For microwave reheating, use 50% power in 1-minute intervals, stirring between each. Avoid boiling—this can make the cream separate. A splash of lemon juice after reheating restores brightness.
