Salmon Roasted with Tomatoes & Olives

The smart move here is roasting the tomatoes alone for 45 minutes BEFORE the salmon ever hits the pan. Plum tomatoes, onion wedges, orange zest, and garlic hang out in a hot oven with olive oil until the tomatoes collapse and caramelize at the edges, concentrating into something between a confit and a rough sauce.

Once that base is built, the oven temperature cranks to 450°F (230°C), chopped kalamata olives and fresh rosemary get stirred through, and four thick salmon portions tuck into cleared pockets. Spoon some of the blistered tomato mixture over each piece. Back in the oven for 10 to 15 minutes until the fish turns opaque in the center.

What you end up with is salmon bathed in a briny, sweet, herbal sauce with real depth. The orange zest is quiet but critical. It bridges the richness of the fish and the savory tomato-olive base.

Chef Tips

• Use ripe plum tomatoes, not beefsteak or slicing tomatoes. Plums have less water and concentrate properly without flooding the pan.
• Stir the tomato mixture every 15 minutes or so during the first roast. This helps even browning and keeps anything from scorching.
• Slivered orange zest, not grated. Strips infuse the oil slowly and stay pretty in the finished dish. Grated zest disappears.
• Check salmon at 10 minutes. Thinner pieces can go from tender to dry fast. A knife tip in the thickest part should meet gentle resistance.

Variations

• Swap salmon for cod, halibut, or thick swordfish steaks.
• Stir in a handful of capers with the olives for more briny punch.
• Add a pinch of red pepper flakes when you add the rosemary for a little heat.
