This pan-seared salmon or trout is served with a bright, creamy dill sauce made with sour cream, mustard, lemon, and fresh herbs. It is a quick seafood dinner that feels polished enough for entertaining but is easy enough for a busy weeknight.
In a small bowl, whisk together the sour cream, mustard, garlic powder or grated garlic, chopped dill, lemon zest, 1 tbsp lemon juice, milk, salt, and sugar until smooth. Add a little more milk if you want a looser sauce, or more lemon juice for extra tang. Let the sauce sit for 10 minutes before serving, or 20 minutes if using fresh garlic.
Pat the salmon or trout fillets dry with paper towels so they sear properly. Season both sides with salt and pepper.
Heat the oil in a large skillet over medium-high heat. Place the fillets in the pan skin-side down and cook for about 2 minutes, until the skin is crisp. Flip and cook for 1 1/2 to 2 minutes more, or until the fish is just cooked through and flakes easily.
Transfer the fish to serving plates. Spoon or serve the creamy dill sauce on the side, and garnish with extra dill and lemon wedges if desired.
For a lighter sauce, you can swap the sour cream for plain Greek yogurt. Do not move the fish too early in the pan or it may stick instead of forming a good crust. Leftover sauce can be refrigerated in an airtight container for up to 2 days.
