Ingredients
-
12 oz (340 g) bucatini or spaghetti
-
1 lb (450 g) shallots, thinly sliced
-
4 cloves garlic, finely minced
-
1 tsp red pepper flakes (reduce for mild)
-
4–6 anchovy fillets, chopped (optional but recommended)
-
6 oz (170 g) tomato paste
-
¼ cup (60 ml) extra-virgin olive oil
-
1 tsp kosher salt, plus more for pasta water
-
½ tsp freshly ground black pepper
-
1 cup (240 ml) reserved pasta water, as needed
-
1–2 tsp red wine vinegar or lemon juice, to finish
-
½ cup (25 g) chopped fresh parsley
-
½ cup (45 g) finely grated Parmesan (more for serving)
Instructions
-
Boil the pasta. Bring a large pot of salted water to a rolling boil. Cook pasta until al dente. Reserve 1–1½ cups pasta water and drain.
-
Caramelize the shallots. While pasta cooks, heat olive oil in a wide skillet over medium heat. Add shallots and ½ tsp salt. Cook, stirring often, until soft, jammy, and lightly caramelized, 10–12 minutes.
-
Build the flavor base. Stir in garlic, red pepper flakes, and anchovies. Cook 1 minute until fragrant and the anchovies melt into the oil.
-
Tomato paste time. Add tomato paste and cook 2–3 minutes, stirring, until it deepens to brick red and sizzles.
-
Make the sauce. Splash in ¾ cup reserved pasta water, scraping the pan to create a glossy, emulsified sauce. Season with remaining salt and pepper.
-
Toss the pasta. Add drained pasta to the skillet. Toss vigorously, adding more pasta water as needed until every strand is well coated and saucy.
-
Finish & serve. Off the heat, stir in vinegar/lemon juice, parsley, and Parmesan. Taste and adjust seasoning. Twirl into bowls and top with extra Parmesan and parsley.
Notes
-
Anchovy umami: They melt completely—no fishy taste, just depth. For vegetarian, skip anchovies and add 1 tbsp white miso for savory richness.
-
Shallot care: Slice evenly so they soften at the same rate; if they start to brown too quickly, reduce heat and add a splash of water.
-
Sauce sheen: Cook the tomato paste until it darkens—this step builds sweetness and complexity.
-
Make-ahead: Caramelized shallot sauce keeps 4 days refrigerated or 2 months frozen. Thin with pasta water when reheating.
-
Heat level: Adjust chili flakes to taste or add a knob of butter at the end to mellow the spice and add silkiness.
