Additional Tips

Choose Even-Sized Fillets: Opt for salmon fillets of similar size to ensure they cook evenly.
Preheat the Pan: Place the sheet pan in the oven during preheating. Adding the ingredients to a hot pan helps crisp up the potatoes.
Season Generously: Don’t skimp on salt, pepper, and any other seasonings for both the salmon and vegetables. It enhances the overall flavor.
Cut Potatoes Uniformly: Dice the potatoes into evenly sized pieces so they cook at the same rate. Smaller pieces cook faster and get crispier.
Dry the Salmon Skin: Pat the salmon skin dry with a paper towel before cooking. This step helps achieve crispy skin.
Use Fresh Herbs: Sprinkle fresh dill, parsley, or chives over the finished dish for a burst of fresh flavor.
Add Lemon Slices: Place thin slices of lemon on top of the salmon for a subtle citrus infusion while it bakes.
Monitor Cooking Time: Salmon cooks quickly, so check for doneness a few minutes before the recipe’s suggested time. Overcooking can make it dry.
Toss Romaine Last Minute: Roast romaine for just 2–3 minutes to keep it slightly crisp and charred without becoming soggy.
Make It a Meal: Pair the dish with a simple yogurt-dill sauce or a drizzle of tahini for added richness and flavor.
