This sardine salad is a quick, nutritious option for lunch or a light dinner that transforms humble canned sardines into a delicious spread. The combination of creamy mayo, crunchy red onion, and fresh herbs elevates this simple dish into something special you'll want to make again and again.
I first made this sardine salad when looking for a nutritious lunch option that wouldn't require a trip to the store. Now it's become my go-to protein-packed meal when I need something satisfying but don't have much time to cook.
Ingredients
- Canned sardines: Provide exceptional nutrition and a rich flavor base that makes this salad special. Look for wild-caught varieties packed in olive oil for best flavor.
- Mayo: Creates the creamy texture. Choose a high quality mayonnaise or even make your own for best results.
- Red onion: Adds a sharp bite and crunch. Select firm onions with dry outer skins for the freshest flavor.
- Fresh parsley: Brightens the salad with its clean flavor. Italian flat-leaf parsley works particularly well here.
- Fresh dill: Brings a distinctive herbaceous note that pairs perfectly with the fish. Always choose vibrant green sprigs.
- Lemon pepper seasoning: Adds both citrus and spice in one ingredient. The acidity balances the richness of the sardines.
- Hot sauce: Introduces a pleasant heat that can be adjusted to your preference. Louisiana-style hot sauces work particularly well.
- Seasoning salt: Helps tie all the flavors together. Look for a quality blend with herbs and spices.
Step-by-Step Instructions
- Prepare the sardines:
- Drain the canned sardines thoroughly by pressing the lid against the fish while tilting the can over the sink. This removes excess oil or water and prevents your salad from becoming soggy. Transfer the drained sardines to a medium-sized mixing bowl.
- Add the aromatics and herbs:
- Measure and add the mayo, finely chopped red onion, chopped parsley, and dill to the bowl with the sardines. Start with 1 tablespoon of mayo for a firmer texture or use 2 tablespoons if you prefer a creamier consistency.
- Season the mixture:
- Sprinkle the lemon pepper seasoning and seasoning salt over the ingredients. If you enjoy a bit of heat, add a few dashes of hot sauce at this stage. Remember that you can always add more seasoning later, but you cannot remove it.
- Combine and mash:
- Using the back of a fork, gently mash the ingredients together until they reach your desired consistency. Some people prefer a smoother spread while others enjoy more texture with visible pieces of sardine. Continue mashing and mixing until everything is well incorporated.
- Taste and adjust:
- Take a small sample and adjust any seasonings as needed. This is the time to add more mayo if it seems dry, additional hot sauce for heat, or extra seasoning salt if the flavor needs brightening.
- Serve appropriately:
- Spread your finished sardine salad on bread for a sandwich, serve it with crackers, or wrap it in lettuce leaves for a low-carb option. Add fresh sliced tomatoes, cucumber, or avocado as accompaniments for a complete meal.

The fresh herbs truly transform this simple dish. I was amazed at how adding just a teaspoon each of parsley and dill elevated the humble sardine into something I genuinely look forward to eating. My favorite memory with this dish was introducing it to my skeptical friend who claimed to hate fish. She ended up asking for the recipe before leaving!
Storage Tips
This sardine salad will keep beautifully in an airtight container in the refrigerator for up to 2 days. The flavors actually improve after a few hours as the ingredients meld together. If the mixture seems to dry out in storage, simply add a touch more mayonnaise before serving. I recommend not freezing this salad as the texture of the mayonnaise can become unpleasant when thawed.
Versatile Serving Ideas
While a classic sardine salad sandwich is delicious, there are numerous ways to enjoy this protein-packed spread. Try it piled onto cucumber slices or endive leaves for a low-carb appetizer. Stuff it into hollowed out tomatoes for an impressive lunch presentation. My personal favorite is serving it atop toasted sourdough bread with sliced avocado and a sprinkle of microgreens. For a Mediterranean twist, serve alongside olives, roasted red peppers, and a drizzle of good olive oil.

Ingredient Swaps
This recipe welcomes substitutions based on what you have available. No fresh herbs? Use half the amount of dried herbs instead. Mayo can be swapped for Greek yogurt for a tangier, lighter version. Red onion can be replaced with shallots or green onions for a milder flavor. If lemon pepper seasoning isn't in your pantry, simply add fresh lemon zest and a few cracks of black pepper. For a different flavor profile altogether, try adding curry powder or smoked paprika to create international variations.
