Swordfish Involtini with Steamed Spinach

Swordfish involtini is a classic Sicilian move: take a firm, meaty fish like swordfish, pound it thin, roll it around a punchy filling, and braise in tomato until tender. This version keeps the filling tight and simple (toasted pine nuts, garlic, Italian parsley, black pepper) so the fish stays the star instead of drowning in stuffing.

The filling gets built in one pan. Garlic browns lightly in olive oil, then pine nuts toast in the same oil until golden and nutty. Watch the pine nuts: they go from perfect to burnt in under a minute and will ruin the whole dish.

The braise is fast and finishes in the oven. Tomato sauce, white wine, and chili flakes come to a boil in an oven-safe pan, the rolls go in seam-side down, and 6 to 8 minutes at 450°F (230°C) is all the fish needs. Torn fresh mint on top at the end cuts through the richness with a cooling herbal note.

Chef Tips

• Ask your fishmonger to slice swordfish thin (about ¼-inch) for you, or freeze the steak for 20 minutes before slicing for cleaner cuts.
• Use toothpicks to secure each roll and remove them before serving. Unrolled involtini look sad on the plate.
• Don’t skip the fresh mint finish. It’s the signature brightness that lifts the dish from heavy to balanced.
• Serve with crusty bread to mop up the tomato-wine sauce or over soft polenta.

Variations

• Swap swordfish for tuna steaks or thick flounder fillets depending on what’s at the counter.
• Add a handful of currants or raisins to the pine nut filling for a more traditional Sicilian sweet-salty balance.
• Stir capers and chopped olives into the tomato sauce for a puttanesca-style braise.
