Pat the salmon dry with a paper towel. Sprinkle the skinless side of the salmon with salt and pepper.
Heat a cast iron or other heavy skillet to medium high heat. Add the oil and place the salmon skin side up. Cook for about 4-5 minutes.
Carefully flip the salmon and turn the heat to medium low. Continue to cook till the salmon flakes easily, usually 3-4 minutes. Remove salmon from skillet.
Turn the pan to low and add the cream, lemon juice, garlic, salt, and lemon zest. Stir till heated through. Serve over salmon.
