Pasta with Sardines, Bread Crumbs, and Capers

1. Prepare Pasta Water

Begin by setting a large pot of water over high heat. Add a generous pinch of salt and bring to a rolling boil; this will be for cooking the pasta later.

2. Toast Bread Crumbs

While the water is heating, place a medium skillet over medium heat and pour in 2 tablespoons of the olive oil. When the oil shimmers, scatter in the bread crumbs. Stir them frequently, keeping a watchful eye as they toast to a golden brown, exuding a nutty aroma. This should take you less than five minutes. Once done, transfer them to a bowl to prevent further cooking.

3. Sauté Onions

Using the same skillet, now softened with the flavors of the bread crumbs, add the remaining 2 tablespoons of olive oil. Tumble in the chopped onion, season with salt and pepper, and sauté until the onions are tender and translucent, which should take about 5 minutes. The sweetness of the onion will infuse the oil, creating a fragrant base for the dish.

4. Cook Pasta

At this point, your pasta water should be boiling. Introduce the pasta to the pot and cook according to the package instructions until just tender. It's crucial to keep the pasta al dente as it will continue to absorb flavors once combined with the sardine mixture.

5. Prepare Sardine Mixture

As the pasta cooks, add the lemon zest, capers, and sardines to the skillet with the onions. Warm the mixture over medium-high heat, breaking up the sardines slightly with your spoon. Let this meld for about 2 minutes, allowing the lemon zest to release its bright oils and the capers to impart their briny pop.

6. Combine and Serve

When the pasta is ready, reserve a cup of pasta water, then drain the pasta. In a large mixing bowl or in the skillet if it's big enough, toss the cooked pasta with the sardine mixture, adding most of the toasted bread crumbs and the fresh parsley. If the pasta seems dry, moisten it with a splash of the reserved pasta water to achieve a glossy sheen that clings to the strands. To serve, divide the pasta among plates, sprinkling each serving with the reserved toasted bread crumbs and a smattering of fresh parsley. Give a final taste and adjust the seasoning as you see fit, allowing the simple, robust flavors to shine through in every forkful.
