Ingredients for canned sardine soup
Transform pantry staples into restaurant-quality umami depth with these 14 ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Sardines in Olive Oil 🐟 | 2 cans | Drained, high-quality brand preferred |
| Yellow Onion 🧅 | 1 whole | Medium size, finely diced |
| Garlic Cloves 🧄 | 4 cloves | Freshly minced, aromatic |
| Carrots 🥕 | 2 medium | OR 1 cup diced, organic preferred |
| Celery Stalks 🌿 | 2 whole | Medium size, finely chopped |
| Canned Diced Tomatoes 🍅 | 1 can | 28 oz, San Marzano preferred |
| Vegetable Broth 💧 | 4 cups | Low-sodium, homemade or quality brand |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | High-quality, fruity variety |
| Fresh Lemon Juice 🍋 | 1 tbsp | Freshly squeezed, bright acidity |
| Fresh Parsley 🌿 | ¼ cup | Chopped, flat-leaf preferred |
| Fresh Dill 🌿 | ¼ cup | Chopped, or substitute parsley |
| Heavy Cream 🥛 | ½ cup | Full-fat for richness, optional |
| Salt 🧂 | 1 tsp | Diamond Crystal kosher |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked, coarse grind |
The sardines are non-negotiable for that signature briny richness—Wild Planet or Crown Prince brands deliver the best quality and texture. Look for cans packed in olive oil rather than water, as the oil adds natural fat-soluble vitamins and enhances flavor complexity. San Marzano tomatoes from Italy elevate the acidity profile, though any high-quality canned tomato works in a pinch. Fresh herbs are critical here: flat-leaf parsley and dill provide the bright, aromatic finish that separates this from basic canned soup. For the broth, homemade or low-sodium store-bought prevents overwhelming saltiness, though you can always adjust later.
No fresh dill? Substitute an extra 0.25 cup parsley—it won’t be identical, but the dish remains balanced. Running low on heavy cream? Greek yogurt thinned with broth creates a tangy alternative without sacrificing thickness. The carrots and celery can be swapped for fennel or leeks if you prefer a different aromatic profile. For a tomato-free version, replace the diced tomatoes with an extra 1 cup vegetable broth and 1 tbsp tomato paste. The key ratio to maintain is 1:1:1 between broth, vegetables, and sardines—this ensures proper texture and umami development.
This soup maintains peak flavor for 4-5 days refrigerated when stored in an airtight container with a thin layer of olive oil on top to preserve freshness. For longer storage, freeze in single-serving portions for up to 3 months—the texture remains velvety upon reheating. To maximize efficiency, prep all vegetables and herbs ahead of time, storing them in separate containers in the fridge. The sardines can be opened and drained up to 2 days in advance, though their flavor intensifies when used immediately. Always reheat gently over low heat to prevent curdling if using the cream variation.

Step-by-step instructions for canned sardine soup
This umami-rich soup comes together in a single pot with minimal effort.
Sauté the Aromatic Vegetables
Heat the 2 tablespoons extra-virgin olive oil in a large pot over medium heat. Add the finely diced yellow onion, minced garlic cloves, diced carrots, and finely chopped celery stalks. Cook for 5-6 minutes, stirring occasionally, until the vegetables soften and the onion becomes translucent.
This foundational step builds flavor through caramelization. You'll know it's ready when the vegetables release their natural juices and develop a slightly golden hue. If you notice the garlic starting to brown too quickly, reduce the heat slightly to prevent burning—bitter garlic ruins the delicate balance of this soup.
Incorporate Tomatoes and Broth
Pour in the 1 can canned diced tomatoes (with juices) and the 4 cups vegetable broth. Stir well to combine, scraping up any browned bits from the bottom of the pot. Bring the mixture to a gentle boil, then reduce heat to medium-low and let it simmer uncovered for 8-10 minutes until the vegetables are tender and the flavors meld.
This simmering phase allows the tomatoes to break down slightly, deepening their sweetness and enriching the broth. You'll notice the soup developing a rich, reddish hue—this is your visual cue that the acidity from the tomatoes is integrating with the umami from the broth. Taste occasionally; if the soup needs more salt, add the 1 teaspoon salt now.
Add the Sardines and Herbs
Drain the 2 cans canned sardines in olive oil (reserve the oil for another use if desired) and add them to the pot. Stir gently to distribute the sardines evenly throughout the soup. Add the 0.25 cup chopped fresh parsley and 0.25 cup chopped fresh dill, along with the 0.5 teaspoon ground black pepper. Simmer for an additional 5 minutes to allow the herbs to infuse their bright flavors.
The sardines will begin to flake apart, releasing their rich, briny essence into the soup. This is where the umami intensity peaks—you'll smell that distinctive oceanic aroma that defines this dish. If you prefer a smoother texture, use a spoon to gently break up the larger sardine pieces. The herbs should brighten the soup's profile, balancing the richness.
Finish with Cream and Lemon
Reduce the heat to low and stir in the 0.5 cup heavy cream and 1 tablespoon fresh lemon juice. Simmer gently for 2-3 minutes—just enough time to warm through without curdling the cream. Taste and adjust seasoning if needed, adding a pinch more salt or pepper as necessary.
The cream adds luxurious body while the lemon juice cuts through the richness, creating a perfect balance. You'll notice the soup transform into a velvety texture with a shimmering sheen. This is the moment to assess the seasoning—it should be rich but not overpowering, with a bright finish from the lemon. If the soup feels too thick, stir in 2-3 tablespoons of water to reach your desired consistency.
Serve Immediately
Ladle the soup into bowls and garnish with additional chopped fresh parsley and chopped fresh dill. Serve immediately while hot, as the flavors continue to develop even after cooking.
Each spoonful should deliver a harmonious blend of textures—creamy from the broth and cream, with flaky sardine bits adding substance. The aroma should be intoxicating, with layers of garlic, herbs, and that unmistakable sardine umami. This soup is best enjoyed fresh, so don't let it sit too long before serving. Pair with crusty bread to soak up every last drop of that flavorful broth.
Pro Tips For Making Canned Sardine Soup
- Sauté Until Golden: Don’t just toss in the onions and garlic—cook them until they’re deep golden, not just soft. That’s where the flavor lives, especially when you’re working with canned sardines, which need that caramelized base to shine. (Yes, it takes 5-7 minutes, even if you’re impatient like me.)
- Drain, Rinse, Repeat: Open those sardines, drain the oil, and give the fish a quick rinse under cold water. The canning liquid is salty and can overpower the soup if you skip this—trust me, your taste buds will notice the difference. (Save the olive oil for drizzling later if you’re feeling fancy.)
- Chop Celery Small: Tiny dice, not thick chunks. Celery turns to mush if it’s too big, and you’ll end up with a soup that’s more watery than flavorful. Aim for ¼-inch pieces—this isn’t a salad, it’s a soup that needs texture to hold up.
- Simmer, Don’t Boil: Once everything’s in the pot, keep the heat low enough that you barely see bubbles. Boiling breaks down the sardines too fast, turning them from rich to rubbery. A gentle simmer keeps them tender and lets their flavor meld into the broth. (Your future self will thank you.)

Frequently asked questions
Can I use water-packed sardines instead of olive oil?
While you can substitute water-packed sardines, you'll lose some of the natural richness and fat-soluble vitamins. To compensate, add an extra 1 tablespoon of olive oil when sautéing the aromatics and consider using 1/4 cup coconut milk instead of heavy cream for added body. The flavor will still be delicious but slightly less luxurious.
How do I make this soup without tomatoes?
Simply replace the canned tomatoes with 1 cup tomato paste (mixed with 1/2 cup broth) or 1/2 cup white wine for acidity. For a completely tomato-free version, use 1 extra cup of broth and add 1 teaspoon lemon juice during the final simmer to brighten the flavors. The sardines will still provide plenty of umami depth.
Why does my soup taste too fishy?
Overpowering fishiness usually means the sardines weren't cooked long enough to integrate with the broth. Simmer for the full 5 minutes after adding sardines, then finish with 1 extra tablespoon lemon juice to balance the flavors. For future batches, try using slightly lower-quality sardines—they tend to have milder flavor profiles.
Can I make this soup in an Instant Pot?
Sauté the onions, garlic, carrots, and celery in the Instant Pot for 3 minutes on sauté mode. Add tomatoes and broth, then cook on high pressure for 5 minutes. Quick-release the pressure, add sardines and herbs, then finish with cream and lemon on low heat for 2 minutes. The Instant Pot version cooks in about 15 minutes total.
What's the best way to store leftovers?
Store in an airtight container with a thin layer of olive oil on top to preserve freshness. Refrigerated, it keeps for 4-5 days, while frozen portions last up to 3 months. For reheating, warm gently on the stove over low heat—never microwave directly from frozen to prevent texture separation.
