Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Halve the baby potatoes and place them on the sheet pan, tossing with half of the olive oil, sea salt, and black pepper.
Roast the potatoes for 15 minutes until they begin to turn golden and soften.
Remove the pan from the oven and push the potatoes to one side; place the salmon fillet and trimmed asparagus on the empty space.
Drizzle the salmon and asparagus with the remaining olive oil, lemon juice, lemon zest, and dried oregano.
Return the pan to the oven and roast for another 10-12 minutes until the salmon is opaque and flakes easily with a fork.
While the sheet pan is roasting, bring a small pot of water to a boil, carefully lower in the eggs, and cook for 6.5 minutes.
Immediately transfer the eggs to an ice bath to stop the cooking, then peel and halve them to reveal jammy yolks.
Plate the salmon, potatoes, and asparagus, topping with the halved eggs and a sprinkle of fresh parsley before serving.
