The combination of salmon, broccoli, and red potatoes makes for a wonderful meal. But how to cook them all on one pan without any one component coming out overcooked or undercooked was a puzzle we needed to solve. Our first step was to look at the roasting time for each. Since the potatoes required the most time in the oven and the salmon required the least, we started by roasting the potatoes and broccoli together for the first half of the cooking time and then swapped in the salmon for the broccoli halfway through roasting. Cooking in stages prevents overcrowding the pan, ensuring even cooking. A vibrant sauce of chopped chives, whole-grain mustard, lemon juice, olive oil, and honey completes this one-pan meal. To ensure that all three components emerge from the oven well browned and cooked just right, we roast the potatoes the entire time on the baking sheet (they take the longest) but remove the broccoli before placing the salmon fillets on the sheet.
