Steps

Before you start

Preheat your panini press or skillet to medium-high heat
Drain the sardine can well, discarding liquid and any loose bones
Have all fillings prepped and within arm's reach before assembly

1
Zest and juice the lemon
- Zest the lemon into a small bowl, then juice it.
- You need about 1 tsp zest and 2 tbsp juice.
- Set both aside.

Ready when: Lemon zest is bright yellow and finely grated; juice is extracted
Tip: Use a microplane zester for finest texture, or a vegetable peeler followed by mincing
2
Combine sardines with herbs and lemon
- In a small bowl, gently toss the drained sardines with the chopped parsley, lemon zest, 1 tbsp lemon juice, a pinch of salt, and red pepper flakes if using.
- Mix lightly to avoid breaking up the fish.
- Taste and adjust seasoning with salt and pepper.

Ready when: Sardines are coated evenly with herbs and lemon; no lumps of parsley
Tip: Don't over-mix—keep sardine pieces intact for better texture in the finished panini
3
Assemble the panini
- Place both ciabatta halves on a cutting board, cut-side up.
- Brush the bottom half of each piece lightly with olive oil.
- Layer on the bottom half: half of the white cheddar slices, then half of the sardine-lemon mixture, then the remaining cheddar.
- Drizzle the remaining 1 tsp lemon juice over the top layer.
- Top with the other ciabatta half, cut-side down, and press gently.

Ready when: Both panini are stacked, bread halves are together, and cheese is sandwiched between layers
Tip: Build on the bottom half first so the top doesn't slide; cheese on both sides of the sardines keeps everything in place
4
Butter and grill
- If using a panini press: brush the top and bottom of each assembled sandwich very lightly with softened butter.
- Place both on the press, close the lid, and grill for 3–4 minutes until the bread is golden and crispy and the cheese is melted (you'll see a little ooze at the edges).
- If using a skillet: butter the outside of the bread lightly, place one panini in the skillet over medium-high heat, press gently with a flat spatula for 2 minutes until the bottom is golden, flip, and press again for another 2 minutes.
- Repeat with the second panini.

Ready when: Bread is golden brown and crispy on both sides; cheese is melted (visible at the edges); interior is warm to the touch
Tip: Don't press too hard or too long or the bread will compress and become dense—light pressure for crust, then let heat do the work
5
Rest and serve
- Transfer the panini to a cutting board and let rest for 1 minute to allow the cheese to set slightly.
- Cut each panini in half on the diagonal if desired, and serve immediately.

Ready when: Panini is warm throughout and cheese is just set but still soft
Tip: Serve right away—panini are best enjoyed hot from the press

Tips

Choose canned sardines packed in olive oil, not water or tomato sauce, for the best flavor and texture
Drain the sardine can thoroughly over a small sieve and discard the liquid to prevent a soggy sandwich
If your bread is very thick, carefully slice off a thin layer from the cut side to make assembly easier without creating a lopsided sandwich
For extra creaminess, add a thin spread of good-quality mayonnaise or a touch of Dijon mustard to the bread before layering

Storage & reheating

These panini are best eaten fresh. If you have leftovers, wrap in foil and store in the refrigerator for up to 1 day. Reheat gently in a 300°F (150°C) oven for 5–7 minutes, wrapped in foil, to warm through and restore some crispness to the crust. Do not freeze.

Substitutions

ciabatta bread → focaccia or sturdy sourdough. Choose bread with an open crumb structure that can handle the moisture from the sardines and lemon without becoming soggy
white sharp cheddar cheese → aged gouda or smoked provolone. Both have enough character to stand up to the briny sardines; avoid mild cheeses that will disappear
fresh flat-leaf parsley → fresh dill or a mix of parsley and mint. Dill is classic with fish; mint adds brightness. Use the same amount
canned sardines in olive oil → canned or jarred anchovies, or smoked mackerel. Adjust lemon juice slightly if using a milder fish; anchovies may need less salt overall
