01 - Pat salmon fillets dry with paper towels and season both sides generously with salt and pepper.
02 - Heat olive oil in a large, deep skillet over medium-high heat. Add salmon fillets skin-side down and sear for 3 to 4 minutes until golden and crispy. Flip carefully and cook 1 to 2 minutes more. Transfer salmon to a plate, leaving skin-side down.
03 - In the same skillet, add chopped onion and cook for 2 to 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 to 2 minutes, stirring frequently until lightly golden.
05 - Pour in white wine and let simmer for 1 minute. 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 to 10 minutes, stirring occasionally, until pasta is tender and most liquid has been absorbed.
07 - Nestle salmon fillets skin-side down on top of the orzo. Cover and cook for 3 to 5 minutes until salmon is cooked through and orzo is creamy.
08 - Remove from heat. Stir in butter and Parmesan until melted and incorporated. Sprinkle with chopped parsley and serve immediately with extra lemon wedges.
