Ingredients
4 thick slices crusty sourdough bread
1 garlic clove, halved
Softened butter, as needed
1 large ripe tomato, thinly sliced
1 can sardines (6 to 7 ounces), deboned if you like
¼ small sweet or red onion, thinly sliced
Extra-virgin olive oil, for drizzling
Fresh lemon juice, to taste
Flaky sea salt
Coarsely ground black pepper
Fresh basil leaves, torn (optional)
Preparation
- Step 1
Toast the bread under a broiler (on both sides) or in the toaster.
- Step 2
While the toast is still warm, immediately rub it (aggressively!) with the cut side of the garlic clove, then spread toast generously with butter. Top butter with tomato slices and lightly salt them.
- Step 3
Top tomatoes with sardines and then onion slices. Drizzle with olive oil and lemon juice, then season with more salt and pepper. Garnish with basil if you like and serve immediately.

Sardine enthusiasts: take the time to seek out REALLY good sardines and your mind will truly be blown. I've spent the last year sampling different cans (a wonderful obsession!) and there's a huge difference in quality between your supermarket King Oscar and a great can of Portuguese Nuri spicy. Amazon has a decent selection, as does Portugalia Market, and once you find a favorite you'll be able to hunt down good pricing. Because you'll want to buy in bulk. Trust me. It will happen.
We followed this recipe precisely and it was insanely delicious. We were groaning with happiness. Do not skip one thing.
Sardines on crisply toasted fresh rye or some crusty bread is a favorite of mine. I can remember getting it at any diner in New York City, or of course I could make it any time I wanted. My mom always had sardines around, and I still do. I'm happy to see this colorful more sophisticated rendition. It's layered with texture and flavors that go oh so well together. Thanks, Melissa!
This recipe took me right back to my childhood when my Friday lunches often featured sardines with chopped red onions and capers and mayo on rye bread. Unlike my altar boy brothers, I looked forward to those Friday lunches,and often profited from their distaste. Guess I'll have a sardine sandwich today!
Super simple, really delicious. Our first attempt with sardines and we agreed this will be a keeper recipe!
I never use butter, but I love sardine toast and just decided to make it for dinner tonight. I will spray toast with olive oil in my Misto, sprinkle with garlic powder rather than using a raw clove and add a little onion lightly cooked, since I don't care for raw onion. No fresh basil here in winter, but I might add a bit of dried basil or oregano. Even better if you can find fresh grilled sardines, a world above any canned ones.
