Ingredients Breakdown
For the Fish:
-
4 Fish Fillets (Cod, Halibut, Tilapia) – Mild, flaky white fish that absorbs the lemony sauce beautifully.
-
Salt and Pepper – Essential seasoning for enhancing natural fish flavor.
-
1 tbsp Olive Oil – Helps sear the fish to a golden crust.
-
Lemon Slices (for garnish) – Adds visual appeal and a hint of extra citrus.
For the Lemon Sauce:
-
2 tbsp Unsalted Butter – Adds richness and balances acidity.
-
2 Garlic Cloves, Minced – Provides aromatic flavor as the sauce base.
-
1/4 cup Fresh Lemon Juice – Gives the sauce its bright, tangy backbone.
-
1 tsp Lemon Zest – Intensifies the citrus aroma and taste.
-
1/4 cup Chicken or Vegetable Broth – Adds savory depth without overpowering the lemon.
-
1 tsp Dijon Mustard – Offers a mild tang and helps emulsify the sauce.
-
Salt and Pepper, to Taste – Balances all flavors.
-
1 tbsp Fresh Parsley, Chopped – Lends color and a fresh, herbaceous finish.
Tips and Tricks
-
Don’t overcook the fish. White fish cooks quickly — remove it as soon as it’s opaque and flakes easily.
-
Use fresh lemon. Bottled lemon juice won’t deliver the same bright flavor.
-
For extra richness, add a splash of cream to the sauce at the end.
