Steps

Before you start

Remove smoked mackerel from the refrigerator 5 minutes before cooking so it's not ice-cold when flaked
Bring a large pot of salted water to a rolling boil for pasta (if serving with pasta)
Have lemon zested and juiced, and garlic minced—all prep done before you start cooking

1
Sauté garlic and aromatics
- Heat 3 tablespoons (45 ml) extra-virgin olive oil in a large 12-inch (30 cm) saucepan over medium heat.
- Once shimmering, add 3 minced garlic cloves and ¼ teaspoon (0.5 g) red pepper flakes if using.
- Stir constantly for 1 to 2 minutes until the garlic is fragrant and just beginning to turn golden—do not let it brown.

Ready when: Garlic is fragrant and pale golden, not brown
Tip: Watch the garlic carefully—it burns quickly and will taste bitter. Keep the heat at medium, not higher.
2
Build the base
- Pour in ¼ cup (60 ml) low-sodium broth and ½ cup (120 ml) heavy cream.
- Stir to combine, then let the mixture warm through for 1 minute.
- The sauce should be smooth and creamy.

Ready when: Sauce is steaming and uniform in color; no cold spots visible
3
Add lemon and flake mackerel
- Squeeze in 3 tablespoons (45 ml) fresh lemon juice and stir.
- Flake the 10 oz (280 g) smoked mackerel directly into the sauce with your fingers or two forks, breaking it into bite-sized pieces and removing any stray bones.
- Gently fold the fish into the sauce with a wooden spoon.

Ready when: Fish is distributed throughout the cream sauce and beginning to soften from the heat
Tip: Smoked mackerel is already fully cooked; you're just warming and gently combining it. Avoid aggressive stirring, which breaks the fish into too-small pieces.
4
Fold in capers and zest
- Stir in 2 tablespoons (20 g) drained capers (if using) and 1 teaspoon (2 g) finely grated lemon zest.
- Heat gently for 1 minute, stirring occasionally, until the sauce is hot throughout but not simmering.

Ready when: Sauce steams gently; a few small bubbles appear around the edges but it is not boiling
Tip: Keep heat moderate to preserve the delicate texture of the mackerel. If it simmers hard, the fish becomes mealy.
5
Season and finish
- Taste and season with kosher salt and freshly ground black pepper to your preference.
- Keep in mind that the smoked mackerel and capers (if used) are already salty, so adjust carefully.
- Stir in ¼ cup (15 g) finely chopped fresh flat-leaf parsley.

Ready when: Parsley is evenly distributed and sauce is well-seasoned and bright-tasting
Tip: Taste before adding salt. Smoked mackerel is already quite briny, so you may need less salt than you'd expect.
6
Serve
- Divide the sauce among pasta bowls or plates.
- If serving with pasta (linguine or spaghetti work best), toss the hot drained pasta with the sauce immediately and serve.
- Alternatively, serve as a light broth over crusty bread or with roasted vegetables.
- Finish with an extra drizzle of olive oil and a crack of black pepper.

Tip: The sauce will thicken slightly as it cools, so serve immediately while it still has a silky, pourable consistency.

Tips

Smoked mackerel is already fully cooked and quite assertive in flavor, so this sauce is quick and bold. If you prefer something gentler, try smoked trout instead.
For the cleanest sauce, remove the skin from the mackerel fillets before flaking—it helps the fish break apart more naturally and gives a better texture.
This sauce is lean on dairy compared to classic cream sauces, which lets the fish and lemon shine. If you prefer it richer, increase the cream to ¾ cup (180 ml) and reduce the broth to 2 tablespoons (30 ml).
Serve with linguine, spaghetti, or even orzo pasta. A squeeze of fresh lemon at the table adds extra brightness for anyone who wants it.

Make ahead

The sauce can be prepared up to 4 hours ahead and stored in the refrigerator in an airtight container. Reheat gently over low heat, stirring frequently, until it just begins to steam—do not boil. Add a splash of water or broth if it has thickened too much.

Storage & reheating

Refrigerator: up to 3 days in an airtight container. Freezer: up to 2 months (freeze without parsley; add fresh parsley after reheating). Reheat over low heat on the stovetop, stirring gently, or in a microwave at 50% power in 30-second intervals.

Substitutions

smoked mackerel fillets, skin removed → Smoked trout fillets. Use the same weight (10 oz / 280 g). Trout is slightly milder and will give a more delicate flavor, but the sauce will remain silky and bright.
heavy cream → Full-fat Greek yogurt or crème fraîche. Use ½ cup (120 ml) and stir it in off heat at the very end to prevent curdling. The sauce will be tangy and slightly thinner, which is delicious with the lemon.
drained capers → Pitted green or Castelvetrano olives, roughly chopped. Use 2 tablespoons (20 g) for the same briny punch. The sauce will be slightly nuttier in flavor.
fresh flat-leaf parsley → Fresh dill or a mixture of dill and parsley. Use the same amount (¼ cup / 15 g). Dill pairs beautifully with smoked fish and adds a subtle anise note.
