  1. Boil the pasta

    Cook the spaghetti in well-salted water until just shy of al dente (about 1 minute less than the package says). Reserve 250 ml of pasta water before draining.

  2. Sizzle the aromatics

    Meanwhile, warm the olive oil (plus a spoon of the sardine oil) in a large skillet over medium heat. Cook the garlic and chili flakes 1-2 minutes until the garlic is pale gold, not brown.

  3. Add sardines and lemon

    Add the sardines, breaking them into large chunks with a spoon, plus the lemon zest. Toss gently for 1 minute so the fish warms through and picks up the garlic oil.

  4. Emulsify

    Add the drained pasta to the skillet with the lemon juice and a splash of pasta water. Toss vigorously over the heat until the water, oil and starch form a glossy sauce that clings to every strand, adding more pasta water as needed.

  5. Serve

    Off the heat, fold in the parsley and parmesan. Divide among warm bowls with extra chili flakes and black pepper.

Why this helps

Omega-3s and calcium on a budget

Two cans of sardines cost less than a coffee and deliver 1.8 g of omega-3s plus 320 mg of calcium from the soft, edible bones, a combination almost no other cheap protein offers. This is pantry cooking at its smartest: 30 minutes, one pot of pasta, and nutrition that rivals salmon.

Questions, answered

Do sardines make the pasta taste fishy?
Less than you'd think. Good canned sardines in olive oil taste meaty and savory, not fishy, and the lemon, garlic, chili and parmesan are specifically there to keep everything bright and balanced.
How much omega-3 is in sardine pasta?
About 1.8 g of EPA + DHA per serving (113% of the daily adequate intake). Sardines are one of the richest omega-3 sources per dollar of any food.
Do you eat the bones in canned sardines?
Yes. They're soft, completely edible, and they're the reason this pasta has 320 mg of calcium per serving (25% DV). You won't notice them in the finished dish.
Can I use fresh sardines?
You can, but it's a different dish: grill or pan-fry fresh sardines and lay them over the finished pasta rather than breaking them into the sauce. This recipe is engineered around canned.
Are sardines sustainable?
Among the most sustainable fish you can buy: they're low on the food chain, reproduce quickly, and MSC-certified options are widely available and cheap.
What about mercury in sardines?
Sardines are small and short-lived, so they accumulate very little mercury. They're considered one of the safest fish to eat regularly, including a couple of times a week.
Can I make this gluten-free?
Yes. Use your favorite gluten-free spaghetti and keep everything else the same. Reserve the pasta water as usual; GF pasta water is starchier, so you may need a touch less.
I really can't do sardines. What else works?
Canned mackerel is the closest swap (similar omega-3s). Canned tuna works too, but you'll lose the calcium since tuna has no edible bones.
