Mashed Sardines on Whole-Grain Sourdough Bread with a Lemon Wedge (Calcium from soft bones and omega-3s)
By the QuiteRecipes team (Jamy & Kaïna) | Food Service Professional, Early Childhood Expert & Parents
Mashed sardines on crisp whole-grain sourdough with lemon — soft-bone calcium and omega-3s on toast, ready in 15 minutes.
Tinned sardines quietly carry the day: low-mercury, high in DHA omega-3s, and, because the soft little bones mash right in, a sneaky source of calcium. On crisp whole-grain sourdough with a lemon wedge, it is a fifteen-minute lunch that tastes far more polished than it is.
🥄 Ingredients
- 🫗 2 tins small sardines in olive oil (about 120g drained each)
- 🫗 4 slices whole-grain sourdough
- 🫗 1/4 small red onion, finely diced
- 🫗 2 tablespoons chopped fresh parsley
- 🫗 1/2 lemon, to serve
- 🫗 Freshly ground black pepper

👨🍳 Instructions
Drain the sardines and tip them into a bowl.
Mash them lightly with a fork — no need to pick out the soft bones; they mash in and are a superb calcium source.
Stir through the onion, parsley, and a good grind of pepper.
Toast the sourdough until crisp and pile the sardine mixture on top.
Serve each plate with a lemon wedge to squeeze over just before eating.
⚠️ Common Mistakes
- ✕
Over-mashing the sardines into a paste; a loose, chunky mash is far more pleasant.
- ✕
Buttering and salting the toast — the sardines are salty enough already.
- ✕
Serving straight from the fridge; room-temperature fish tastes notably better.
🔄 Variations
Add a scrape of Dijon mustard under the pile.
Top with a few thin cucumber rounds or a grate of carrot for crunch.
Serve open-face on dark rye bread instead of sourdough.
🧊 Storage
- 📦
The mash keeps a day in the fridge; toast fresh to order.
- 📦
Best eaten immediately while the toast is crisp.
💡 Chef Tips
Tip 1: Buy skinless-and-boneless tins if bones put you off, but the soft little bones are pure calcium.
Tip 2: Sardines are small, low-mercury fish — one of the safest high-omega-3 choices during pregnancy and while nursing.
Tip 3: Toast the bread well so it holds up to the mashed fish without going soggy.
Tip 4: A little lemon zest stirred into the mash also cuts fishiness nicely.
❓ FAQ
Q
Are sardines safe during pregnancy? Yes — they're small, low-mercury fish packed with DHA, and canned sardines are already fully cooked.
Q
Do I really eat the bones? The tiny bones in the tin are soft and edible — mashed in, they become a stealth calcium boost.
Q
It's a little salty — is that okay? Sardines are naturally salty; if you're watching sodium, choose tins in water and skip the added salt.
