Sardine Pasta with Fennel and Raisins
Pasta con le sarde is Sicily's sardine pasta, and on paper it reads like an argument. Oily fish meets sweet raisins and anise meets saffron, with pine nuts in the middle keeping the peace. On the plate the argument settles: the raisins make the sardines taste cleaner, and a crust of toasted breadcrumbs gives every forkful something to bite. Italy lists the dish among its traditional agri-food products, with Bagheria, in the province of Palermo, named as its area of production. The recipe in that listing is built on bucatini, sardines, wild mountain fennel, raisins and pine nuts.
Wild mountain fennel is not a Denver produce-bin item. This version is built from the shelf and one trip to that bin, and each substitution changes the method. Tinned sardines in olive oil are already cooked, so they go in at the end to warm through. A fennel bulb, its stalks, its fronds and a spoon of fennel seed rebuild the wild plant between them. The saffron is steeped at the temperature that pulled the most color in a 2024 study.
Ingredients, for four
- 400 g (14 oz) dried bucatini or spaghetti; bucatini is the shape in the traditional-products listing
- 2 tins (about 110 to 125 g each) sardines in olive oil, such as Conservas de Cambados small sardines (shop Conservas de Cambados small sardines) or Ati Manel sardines in olive oil and lemon (shop Ati Manel sardines in olive oil and lemon); keep the oil
- 2 anchovy fillets in oil
- 1 medium fennel bulb with stalks and fronds, about 300 g
- 1 teaspoon fennel seed, lightly crushed
- 1 small yellow onion, finely chopped
- 40 g (1/4 cup) raisins or golden sultanas
- 30 g (1/4 cup) pine nuts
- A good pinch of saffron threads (shop saffron threads), about 25
- 5 tablespoons extra virgin olive oil, divided
- 50 g (3/4 cup) coarse dry breadcrumbs
- 1/4 teaspoon chile flakes, optional
- Fine sea salt for the water, at one percent
- To finish, optional: the zest of half a lemon and a pinch of fennel pollen (shop fennel pollen)
Method
- Steep the saffron first. Crumble the threads between two fingers into 3 tablespoons of hot water, about 140°F (60°C), too hot to hold a finger in but nowhere near a simmer. Just-boiled water poured into a cup and left to cool gets there, and a thermometer settles it. Leave it for 20 minutes while everything else happens; the water turns a deep amber. Cover the raisins with warm water in a second cup.
- Toast the crumbs and the nuts. Warm 1 tablespoon of the oil in a wide skillet over medium heat, add the breadcrumbs and stir constantly for 3 to 4 minutes until they are evenly golden and smell of toast. Salt them lightly and tip them into a bowl. Toast the pine nuts in the same dry pan for 2 to 3 minutes, shaking, until pale gold, and set them aside. Pull them early rather than late.
- Make the fennel water. Bring 4 to 5 quarts of water to a boil and salt it at one percent. Cut the stalks off the fennel bulb and drop them into the pot with a handful of the coarser fronds. Boil them for 5 minutes, then fish them out; the pasta will cook in water that already tastes faintly of anise. Dice the bulb small and chop the finest fronds for the end.
- Cook the fennel slowly. In the skillet, warm the remaining 4 tablespoons of oil and a spoon of oil from the sardine tins over medium-low heat. Add the onion, diced fennel and crushed fennel seed with a pinch of salt. Cook for 10 to 12 minutes, stirring now and then, until the fennel is soft and translucent and has barely colored. Add the anchovies and press them into the oil with a wooden spoon until they dissolve.
- Start the pasta. Drop the bucatini into the fennel water, stir for the first minute so the strands do not stick, and set a timer for 2 minutes under the package time.
- Build the sauce. With about 4 minutes left on the pasta, add the drained raisins, the pine nuts, the chile flakes, the saffron with all its water and a ladle of the pasta water to the skillet. Lay the sardines on top, broken into large pieces, and let them warm through gently for 2 to 3 minutes. Stir as little as possible; a few pieces will break, but the sardines should stay recognizable.
- Drain wet and toss. Take out 2 cups of the cooking water, then drain the pasta while a thin white line remains at the center. Add it to the skillet over medium heat and toss with tongs for 1 to 2 minutes, adding water a splash at a time, until the sauce turns glossy and golden and clings to the strands.
- Finish. Off the heat, toss in the chopped fronds and the lemon zest if using, and taste for salt; between the anchovies and the sardines it may need none. Serve in warm bowls with a thick layer of toasted breadcrumbs on top and a pinch of fennel pollen, and put the rest of the crumbs on the table.
The tin changes the method
Fresh sardines are cooked in the sauce. Tinned ones already have been. Tinned sardines sold in the United States fall under the federal rules for thermally processed low-acid foods in hermetically sealed containers, which require the sealed can to be heated to commercial sterility. The cannery walkthrough follows the fish from the boat to the sealed tin. So a tinned sardine needs warming, not cooking. Put it in at the start with the onions and it collapses into a gray paste that coats the pasta with a flat, heavy fishiness. Put it in for the last few minutes and it stays in soft, rich flakes that taste of the sea rather than of the pan.
The oil in the tin belongs in the recipe too. A spoon of it in the soffritto carries the sardine flavor into the fennel from the start, which is what makes the finished sauce taste of one dish rather than of fish added to vegetables. The rest can toast the next batch of breadcrumbs; the guide to the oil left in a tin of fish has more uses for it.
Why the saffron is steeped at 140°F
Three compounds in saffron matter in a pan. Crocins give the color, picrocrocin the taste and safranal the scent. A 2024 study in the journal Molecules infused saffron in water, olive oil and two water-oil mixes at temperatures from 10 to 100°C for 10 to 30 minutes, and found the crocins at their highest concentration in water at 60°C after 20 minutes. It also found that cooking heat reduces both the crocins and the safranal, while picrocrocin held steady from 10 to 60°C. Safranal came out most readily at 80°C in a mix of one part water to two parts oil.
Each part of that finding lands in the method. The threads steep at 60°C for twenty minutes before anything else is cooked, the condition that pulled the most color. The saffron water goes into the skillet in the last few minutes, so the heat has little time to work on it. It joins a pan of olive oil and pasta water, closer than plain water to the oil-and-water mix that gave up the most scent in the study. Stirring dry threads straight into a hot soffritto skips the steep that drew out the most color.
Rebuilding the wild fennel
Illinois Extension describes two kinds of fennel. Herb fennel is harvested for its stems, leaves and seeds. Florence fennel is shorter and is grown for the flat, thick rosette of leaf stalks at its base, often called a bulb. In the Sicilian recipe the wild mountain fennel is blanched before it goes into the sauce, so this version blanches the stalks and coarse fronds in the pasta water and gives the rest of the cultivated plant separate jobs. The diced bulb cooks down slowly with the onion into the sweet base of the sauce, and crushed seed concentrates the anise. The fine fronds go in raw at the end, and a pinch of fennel pollen on top repeats the anise at the plate.
Why it went wrong
| Symptom | Cause | Fix |
|---|---|---|
| Heavy and fishy | The sardines went in early and cooked to paste | Add them in the last 2 to 3 minutes, in large pieces, and stir as little as possible |
| Pale, with little saffron flavor | The threads went in dry, or the saffron water boiled for a long time | Steep in hot, not boiling, water for 20 minutes and add it near the end |
| Too sweet | Too many raisins, or an onion cooked too dark | Keep to 40 g for four and cook the onion and fennel low until soft, not brown. A squeeze of lemon at the table helps. |
| Soggy crumbs | They were tossed into the sauce | Crumbs go on top at the plate and on the table, never into the pan |
| Dry and tight | Too little water in the toss, or the pasta sat | Toss with water a splash at a time until glossy, and serve at once |
| Bitter | The pine nuts or fennel seed scorched | Toast the nuts in a dry pan over medium heat and pull them at pale gold; keep the soffritto at medium-low |
Notes and variations
The pasta. Bucatini is the listing's shape and the best one here, since the hollow center holds a little of the saffron sauce. Spaghetti works well. Cook either by the method in how to cook dried pasta properly, with the same one percent salt and the same finish in the pan. The sardines. Sardines in olive oil are the right tin, plain or with lemon. Small sardines give tender flakes, larger ones meatier pieces. Sardines in tomato sauce belong to a different dish. Almonds, toasted and chopped, can replace the pine nuts. The anchovies are optional with sardines already in the pan, but two fillets dissolved into the oil deepen the base the same way they do in the aglio e olio with anchovy. Baked, the leftovers become a second meal: press them into an oiled dish, cover with more crumbs and bake at 400°F until the top crisps.
In Denver. Colorado State University Extension puts the boiling point of water at about 203°F at 5,000 feet, against 212°F at sea level, and notes that foods cooked by boiling therefore require a longer cooking time, while liquids evaporate faster. For this recipe that means tasting the pasta from the package time rather than two minutes under, and saving the full 2 cups of water, since the sauce loses water faster at altitude and tightens sooner. The altitude guide covers the rest of the stove.
