Directions
Preheat your oven to 375°F / 190°C. Lightly brush a 15x10x1-inch baking pan with olive oil.
Arrange the trimmed asparagus and cod fillets in a single layer on the prepared pan. Scatter the halved cherry tomatoes around them, cut-side down.
Brush the cod fillets with fresh lemon juice, then sprinkle evenly with lemon zest, salt, and pepper.
Generously sprinkle the Romano cheese over both the fish and the vegetables.
Bake for 12-15 minutes, or until the cod is opaque and flakes easily with a fork.
For a beautiful golden-brown finish, switch the oven to the broiler setting.
Place the pan 4-6 inches from the heat and broil for 2-3 minutes, watching carefully to prevent burning.
Serve immediately.
Pat the cod fillets completely dry with a paper towel before seasoning. This helps them get a better texture and prevents them from steaming in the oven.
Don't overcrowd the pan. Give the vegetables and fish enough space to roast rather than steam. Use two sheet pans if necessary for the best results.
