Transforming humble pantry staples into a rich, umami-packed soup is exactly what this canned sardine soup recipe delivers—proof that bold flavors don’t require hours or fresh ingredients.

Ingredients for canned sardine soup
Pantry staples meet bold flavors in this 15-minute sardine soup—no fresh fish needed.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Sardines in Olive Oil 🐟 | 2 cans | Drained, oil reserved for soup |
| Canned Crushed Tomatoes 🍅 | 1 can | 28 oz, San Marzano preferred |
| Yellow Onion 🧅 | 1 whole | Medium, diced small |
| Garlic Cloves 🧄 | 4 cloves | Minced, fresh preferred |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | Reserved from sardines plus extra |
| Vegetable Broth 💧 | 2 cups | Low-sodium preferred |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Fresh Parsley 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Dill 🌿 | ¼ cup | Chopped, or 1 tsp dried |
| Red Chili Flakes 🌶️ | ½ tsp | Adjust for heat preference |
| Sea Salt 🧂 | 1 tsp | Adjust to taste |

| Potatoes 🥔 | 1 lb | Yukon gold, diced small |
| Coconut Milk 🥥 | ½ cup | Full-fat, optional for creaminess |
The sardines are the star, so grab the best quality you can find—look for brands like Wild Planet or Ocean's Pride, packed in olive oil (not water). The oil from the cans adds richness, so reserve it all—don’t drain it completely. For the tomatoes, San Marzano is ideal, but any good-quality crushed tomatoes work. Potatoes add heartiness, but skip them if you prefer a lighter broth. The fresh herbs? Buy them in small bunches—they’ll wilt fast, but the flavor is worth it. If you can’t find fresh dill, dried works at one-third the amount, but fresh is better.
No canned tomatoes? Fresh tomatoes blended with broth works in a pinch, though it’ll be less sweet. Short on potatoes? Substitute white beans or chickpeas for extra protein. Want to skip the coconut milk? A splash of cream or extra olive oil gives the same velvety finish. The chili flakes are key for depth—adjust to taste, but don’t skip them entirely. For extra umami, add a teaspoon of soy sauce or fish sauce (trust me, it’s amazing). The broth? Low-sodium is best, but if you only have regular, dilute it with water.
This soup tastes even better the next day—make a double batch and store it in the fridge for up to 5 days. For leftovers, reheat gently on the stove with a splash of water or broth to restore creaminess. Freezes beautifully for 3 months, though the texture changes slightly. Keep the fresh herbs separate until serving—toss them in just before eating so they stay vibrant. If you’re using potatoes, parboil them first to speed up cooking time.

Step-by-step instructions for canned sardine soup
This umami-packed soup comes together faster than you can say "pantry magic."
Sauté Onions and Garlic in Sardine Oil
Drain the 2 cans of canned sardines in olive oil, but don't throw away that golden liquid—it's packed with flavor. Heat the reserved oil in a large pot over medium heat. Add the diced small yellow onion and cook for 5 minutes until softened and translucent. You'll smell the onions release their sweetness as they cook down.
Add the 4 minced garlic cloves and cook for another 1 minute until fragrant. The garlic should just start to turn golden—don't let it brown or it'll turn bitter. Here's the thing—this step builds the aromatic foundation that makes the whole soup sing. If you rush it, you'll miss that deep, savory base.
Add Potatoes and Tomatoes
Toss in the diced small Yukon gold potatoes and stir to coat them in the onion-garlic oil. Cook for 2 minutes to let them absorb some of that flavorful oil. Then pour in the 1 can of canned crushed tomatoes and stir everything together.
Bring the mixture to a gentle simmer over medium-high heat. The tomatoes will help create a rich, slightly thickened base. Let it cook for 5 minutes until the potatoes start to soften slightly at the edges. This is where the magic begins—the tomatoes release their acidity, balancing the richness of the sardines.
Build the Broth Base
Pour in the 2 cups of vegetable broth and the 0.5 teaspoon red chili flakes. Stir well to combine, then add 1 teaspoon sea salt and 0.5 teaspoon freshly cracked black peppercorns. Bring the soup to a full boil, then reduce heat to medium-low and let it simmer uncovered for 10 minutes. You'll see the potatoes soften and the flavors meld together beautifully.
I know it seems like a long wait, but this simmering time lets all the ingredients marry properly. The broth will absorb the flavors from the onions, garlic, tomatoes, and sardines, creating that deep, satisfying taste. If you're worried about the soup getting too thick, just add a splash of water—it's easy to adjust at this stage.
Finish with Sardines and Herbs
Add the drained sardines to the pot and gently stir to distribute them evenly. Cook for another 3 minutes to let the sardines warm through and infuse the soup with their rich, briny flavor. Then stir in the 0.25 cup chopped fresh parsley and 0.25 cup chopped fresh dill. These herbs will brighten up the soup and add a fresh finish.
Finally, stir in the 1 tablespoon freshly squeezed lemon juice and the 0.5 cup full-fat coconut milk (if using). The lemon juice cuts through the richness of the sardines and coconut milk adds a velvety texture. Taste and adjust the seasoning—you might need a little more salt or a splash of lemon juice to balance the flavors just right.
Serve Warm and Enjoy
Ladle the soup into bowls and serve immediately while it's hot. The aroma alone will make your kitchen feel like a cozy Mediterranean bistro. Each spoonful delivers layers of flavor—the briny sardines, the sweet onions, the tangy tomatoes, and the fresh herbs all working together in perfect harmony.
Don't forget to taste as you go—this soup is all about balance. If it needs more acidity, squeeze in a little more lemon juice. If it's too thick, stir in a little more broth. The beauty of this recipe is how adaptable it is to your taste. Serve with crusty bread to soak up every last drop of that umami-packed goodness.
Pro Tips For Making Canned Sardine Soup
- Sauté Onions Low and Slow: I used to rush this step and end up with bitter, caramelized bits instead of sweet, soft onions. For sardine soup, keep the heat at medium-low until the onions are translucent but not browned—you want them to melt into the tomatoes without adding harshness. (Yes, even if you're impatient like me.)
- Drain Sardines, Keep Oil: The olive oil from the can is gold here—don’t toss it. Drain the sardines but reserve that oil; it’s the base for your soup’s richness. If you skip it, you’ll miss the depth that makes this dish sing. (Your future self will notice.)
- Crush Garlic, Don’t Mince: I learned this the hard way—minced garlic burns fast and turns bitter. For this soup, smash the cloves with the flat side of your knife before adding them to the pot. They’ll infuse flavor without overpowering the tomatoes or sardines. (Sounds weird, but it works.)
- Simmer, Don’t Boil: After adding tomatoes and sardines, resist the urge to crank the heat. A gentle simmer (tiny bubbles, occasional skims) lets the flavors meld without breaking the sardines into mush. Boiling turns this into a sad, watery mess. (Steer clear of the urge.)
Regional styles of this recipe
Mediterranean Coastal
This is where sardine soup truly shines—think of the coastal towns of Greece or Spain, where fishermen would return with fresh catches and transform them into simple, flavorful meals.
In this version, I add 1 diced fennel bulb (about 1 cup) along with the onions to create an anise-like sweetness that pairs perfectly with sardines.
Finish with ¼ cup chopped fresh oregano instead of dill, and a splash of white wine (about ¼ cup) when adding the broth. The wine deglazes the pot, adding depth without overpowering the delicate flavors. 🌊
Portuguese-Style Azores
The Azores islands have a deep tradition of sardine dishes, and their version of this soup often includes potatoes cooked in the skin (about 4 small potatoes, halved) for extra heartiness.
I also stir in ½ cup chopped escarole or endive at the very end for a bitter contrast that cleanses the palate. For an authentic touch, add 1 bay leaf when simmering the broth and remove it before serving.
The Azores version is all about rustic simplicity with bold flavors. 🌋
North African Tagine-Inspired
For a warm, spiced twist, transform this soup into a tagine-style dish by adding 1 teaspoon ground cumin, ½ teaspoon ground coriander, and ¼ teaspoon cinnamon with the onions.
Use chicken broth instead of vegetable, and stir in ½ cup chopped preserved lemon peel (the kind from Moroccan markets) for a bright, citrusy kick. Top with toasted almonds before serving—this version tastes like a cozy North African stew. 🌶️
Modern Nordic Twist
Scandinavian cooks often embrace bold, simple flavors, and this version is no exception. Swap the tomatoes for 1 cup roasted red bell peppers (jarred or fresh) and add ½ cup chopped fresh chives at the end. For a creamy finish, stir in ¼ cup crème fraîche instead of coconut milk.
The Nordic style keeps the dish light yet satisfying, with a focus on natural, bright ingredients. The chives add a delicate onion-like aroma that elevates the soup to restaurant quality. ❄️
Italian Liguria
Liguria, the Italian region famous for its pesto, brings a fresh, herb-forward approach to sardine soup. After simmering the base, stir in ½ cup basil pesto (homemade or store-bought) and fold it gently into the soup.
Add ½ cup diced Kalamata olives and ¼ cup chopped sun-dried tomatoes for a briny, Mediterranean punch. The Ligurian version is all about balancing rich sardines with bright, fresh herbs and a touch of olive oil drizzled on top. This is the soup you’d find in a seaside trattoria. 🍅

Frequently asked questions
Can I make this soup without potatoes?
The potatoes add heartiness, but you can easily omit them for a lighter broth. For extra texture, substitute with ½ cup white beans or chickpeas or keep it simple with just the sardines, tomatoes, and herbs. The soup will still be packed with flavor and protein.
What if I don't have fresh herbs?
No problem! Use 1 teaspoon dried dill and 1 teaspoon dried parsley instead of fresh. For best results, add the dried herbs at the end of cooking rather than during simmering. If you only have one herb, parsley works well on its own—just use 2 teaspoons for extra brightness.
How can I make this soup spicier?
Add 1-2 teaspoons of red pepper flakes when cooking the onions or stir in ½ teaspoon cayenne pepper with the broth. For a smoky kick, add ½ teaspoon smoked paprika or a dash of hot sauce at the end. Remember, you can always adjust heat to taste!
Can I use water instead of broth?
While broth adds depth, you can use water in a pinch. To compensate, add 1 teaspoon fish sauce or soy sauce for umami, or a pinch of kelp powder for a seafood-like flavor. The soup will still be delicious, though the broth will be lighter.
Why does my soup taste too fishy?
This usually happens when the sardines overpower the other flavors. Balance it by adding more lemon juice (1-2 tablespoons) or tomatoes to cut the fishiness. A splash of coconut milk or cream also helps smooth out strong flavors. Taste as you go—this soup is all about balance!
