Sprinkle salt and pepper all over the halibut to your liking.
On a saucepan on medium high heat, add oil and butter and wait for the butter to melt. Add the halibut and sear for 3-4 minutes on each side. Remove the halibut from the pan.
Lower heat to medium low. Using the same pan and the same juice, add 2 tablespoons of butter. Once the butter melts, add the garlic and white wine and bring to a simmer. After three minutes, add the juice of two lemons, capers and parsley.
Add the halibut back on the pan and scoop the juice over and over again onto the halibut. Serve and enjoy!
