Expert Tips for Perfect Creamy Garlic Butter Salmon
1. Get That Perfect Sear
Always start with a hot pan and dry salmon. Moisture prevents browning, and a crisp exterior is key to texture and flavor.
2. Don’t Overcook the Fish
Salmon cooks fast — keep it tender by removing it from the heat when the center is just slightly pink. It will continue to cook in the sauce.
3. Build Flavor in Layers
Use one pan for every step to capture all those caramelized bits — they’re what make the sauce taste incredible.
4. Customize the Sauce
-
Want a lighter meal? Use coconut milk instead of cream.
-
Love spice? Add more chili flakes or paprika.
Serving Suggestions
The creamy sauce pairs beautifully with a variety of sides. Here are a few favorites:
