Foil Packet Lemon Rosemary Halibut (GF, Grain-free)

Servings: 2
Prep Time: 10 minutes
Cook Time: 20 minutes
Total Time: 40 minutes


  • 1 lb halibut, (2 fillets)
  • 6-8 Tbs lemon juice, (3-4 Tbs per fillet, depends on how much sauce you want)
  • sea salt to taste
  • pepper to taste
  • 3 Tbs  greek yogurt, (1.5 Tbs per fillet) ( use 0-2% fat greek yogurt)
  • 2 branches of rosemary, (1 per fillet)
  • 2 slices of lemon, (1 per fillet)


  • Preheat oven to 375 degrees F.
  • Take two large pieces of aluminum foil and place one halibut fillet in the middle of each piece of foil. Curve the ends of the foil, creating a bowl, so you can put liquid in without it falling out.
  • Put 3-4 Tbs of lemon juice on top of each fillet. Top each fillet with heavy pinches of sea salt and black pepper.
  • Then top each fillet with 1.5 Tbs of greek yogurt. Add a branch of fresh rosemary to each fillet, and a slice of lemon as well.
  • Push foil around the top of the fillets until aluminum packets are closed.
  • Cook the fish for 20 minutes. ( Cook time will be more or less depending on how thick your piece of halibut is )
  • Note: Don’t throw away the sauce! Use the lemon greek yogurt rosemary sauce on top of rice, potatoes or veggies.
