How to make it:
Preheat oven to 375° F.

Whisk together melted butter, garlic, basil, lemon juice, salt, and pepper. Set aside. (If you're dairy-free, you can use ghee, avocado oil, or a vegan butter substitute in place of the butter.)

Place a large sheet of aluminum foil on a baking sheet. Layer a piece of parchment paper that is slightly smaller than the foil on top. This double-wrapping technique gives you the benefits of a good, metallic heat conductor while also creating a healthier barrier between the foil and your fish.

Pour half of the lemon-basil sauce over the fillets. Reserve the remaining sauce for later. Top each fillet with the lemon slices.

Close the paper and aluminum foil around fish to make a packet. Make sure there is some room for air ventilation. Bake for 10-15 minutes, depending on the thickness of the filet.

Open the foil packet, pour remaining lemon-basil sauce over fillets. Return to oven under a low broil for 4-5 minutes. Make sure there is no parchment paper showing. Watch closely while broiling. Remove from oven and let rest for 5 mins.

Serve hot with your favorite sides.

Enjoy!
