03 - Pat tilapia fillets dry and place them on one side of the sheet pan. Brush fillets generously with the lemon-herb marinade.

06 - Sprinkle chopped fresh parsley over the cooked ingredients and serve with lemon wedges.

# Expert Advice:

01 -
  • Everything cooks on one sheet pan, so cleanup is almost nonexistent.
  • The lemon-herb marinade is bright and tangy without overpowering the delicate fish.
  • It's naturally gluten-free and low-carb, making it easy to fit into almost any meal plan.
  • The whole meal is ready in 30 minutes, perfect for busy evenings when you're running short on time.
02 -
  • Don't skip patting the tilapia dry, excess moisture prevents the marinade from sticking and can make the fish steam instead of roast.
  • Arrange the green beans in a single layer without crowding, or they'll steam and turn limp instead of getting those crispy, caramelized edges.
  • Check the fish at 18 minutes, tilapia can go from perfectly flaky to overcooked quickly, especially if your fillets are on the thinner side.
03 -
  • Use parchment paper instead of foil if you want the green beans to get a little more caramelized and crispy on the edges.
  • Let the tilapia sit at room temperature for about 10 minutes before roasting so it cooks more evenly and stays tender.
  • Zest the lemon before juicing it, it's much easier and you'll get cleaner, more fragrant zest that way.
