The lemon pulls this flavorful and healthy dish together. You can use grated Parmesan cheese instead of Romano if you'd like. —Thomas Faglon, Somerset, New Jersey


Test Kitchen tips
  • If asparagus isn't in season, fresh green beans make a fine substitute and will cook in about the same amount of time.
  • We tested cod fillets that were about 3/4 in. thick. You'll need to adjust the bake time up or down if your fillets are thicker or thinner.
