01 - Pat salmon fillets dry with paper towels. Season both sides generously with kosher salt and freshly ground black pepper.
02 - Heat olive oil in a large, deep skillet over medium-high heat. Add salmon fillets skin-side down and sear for 3–4 minutes until skin is golden and crispy. Flip carefully and cook 1–2 minutes more. Transfer salmon to a plate (it will finish cooking later).
03 - In the same skillet, add chopped onion and cook for 2–3 minutes, scraping up any browned bits from the bottom. Add minced garlic, dried oregano, and chili flakes; sauté for 1 minute until fragrant.
04 - Stir in orzo pasta and toast for 1–2 minutes, stirring constantly, until lightly golden and aromatic.
05 - Pour in white wine and let simmer for 1 minute until slightly reduced. Add broth, lemon zest, and lemon juice. Stir well to combine and bring to a gentle boil.
06 - Reduce heat to medium-low. Cover skillet and cook orzo for 8–10 minutes, stirring occasionally to prevent sticking, until just tender and most of the liquid is absorbed.
07 - Nestle the salmon fillets skin-side down on top of the creamy orzo. Cover and cook for 3–5 minutes, until salmon is cooked through to desired doneness and orzo is perfectly creamy.
08 - Remove skillet from heat. Stir in butter and grated Parmesan until melted and incorporated. Sprinkle generously with chopped fresh parsley. Serve immediately with extra lemon wedges on the side.
