For 2 servings
- prep · ~1 min
Mash the avocado.
Cut the avocado in half, remove the pit, and scoop the flesh into a small mixing bowl. Add lemon juice, salt, and black pepper. Mash with a fork until mostly smooth with a few chunky bits for texture.
- roast · ~2 min
Toast the bread.
Toast sourdough slices in a toaster or on a hot grill pan until golden brown and crisp on both sides.
TIPThick-cut sourdough holds up better under the toppings—avoid thin sandwich bread that can get soggy. - other · ~1 min
Warm the sardines gently.
Place a small skillet over low heat. Add the drained sardines with a teaspoon of their reserved olive oil. Warm for 30 seconds just until they lose the refrigerator chill—do not cook them.
TIPWarming sardines in their own oil takes the metallic edge off tinned fish and makes them taste fresher. - assemble · ~1 min
Assemble the toast.
Spread the mashed avocado generously over each toasted sourdough slice. Arrange the warmed sardines on top, breaking larger fillets in half if needed to fit.

Finish and serve immediately.
Sprinkle with chili flakes and fresh cilantro. Drizzle a little of the reserved sardine oil over the top for extra richness. Serve right away while the toast is still crisp.
What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Use a ripe avocado that yields slightly to gentle pressure for the creamiest mash.
- 2Warm the sardines in their own oil to mellow the tinny flavor and enhance richness.
- 3Drizzle a little reserved sardine oil over the finished toast for an extra layer of savory depth.
- 4Sprinkle chili flakes just before serving to keep their bright heat from becoming bitter.
- 5Make ahead: mash the avocado up to 30 minutes early and press plastic wrap directly on the surface to prevent browning.
- 6For a non-soggy base, toast thick-cut sourdough until deeply golden and crunchy all the way through.
Adapt it for your goals.
Spicy-mayo
Swap the chili flakes for a smear of sriracha-mayo on the toast before adding avocado. Adds creamy heat and a tangy kick that complements the sardines.
extra crunchExtra-crunch
Top with thinly sliced radish and a sprinkle of toasted sesame seeds. Adds a peppery crunch and nutty flavor that plays against the creamy avocado and oily fish.
herb swapHerb-swap
Replace cilantro with fresh dill or flat-leaf parsley. Changes the herbaceous note to something milder or more peppery, ideal for those who dislike cilantro.
dairy luxeDairy-luxe
Add a thin spread of labneh or goat cheese under the avocado. Adds a tangy creaminess that elevates the toast to a more indulgent open-faced sandwich.
